On Wednesday evening, Education Minister Jason Clare announced key details for the universities accord.

Clare wants to make a “long-term plan” for universities with the terms of reference covering funding, affordability, employment conditions for staff and how universities and TAFEs can work together.

This will be the first broad review of the system since the 2008 Bradley Review.

If the government’s aspirations are met, it will likely mean the most significant changes to Australian higher education in a generation.

It could reshape universities in ways as dramatic as those by former Labor education minister John Dawkins in the 1980s. This saw HECS introduced, and many higher education institutions merged and remade.

What will it look at?

Like the Hawke Government’s Prices and Incomes Accord in 1983, the universities accord is billed as a way to seek consensus around the purpose of Australian higher education, and the policy settings needed to enable this.

Under the terms of reference, the “key areas” for review by the accord include:

  • meeting Australia’s knowledge and skills needs

  • boosting enrolments for First Nations people, people with disability and rural and regional student

  • student fees and government contributions, including a review of the Job-ready Graduates program

  • workplace relations settings with universities

  • the connection between the vocational education and training (which includes TAFEs) and universities

  • the impact of COVID-19 and the role of international students in Australia

  • the research system, which will “synchrnoise” with a current review of the Australian Research Council.

The process will be led by the former University of Adelaide Vice-Chancellor Professor Mary O’Kane, who was the first woman to lead an engineering faculty in Australia. An interim report is due in June 2023, with the final report due in December 2023.

Much at stake

There is lot at stake for students, their communities and the academics and professional staff who educate them with this accord.

Australia’s universities are successful by many measures. Students have been happy overall with the quality of education and Australia remains a popular destination for international students. There are seven Australian universities in the world’s top 100, thanks to the quality and quantity of the research they produce.

However, there is no doubt real challenges lie ahead and are growing more urgent. These include a confused and messy system for domestic student charges, an over reliance by the universities on international fee revenue and a politicised research grants scheme.

The big challenges

Each year, tens of thousands of Australians apply to university, just at the undergraduate level.

The previous government’s Job-ready Graduates program has made this harder for many students, such as for those studying humanities, who are now saddled with a much larger debt. The Coalition claimed the large increase in charges would steer students into courses it said had better job prospects, such as nursing.

University fees are poised to change – a new system needs to consider how much courses cost and what graduates can earn


There is little evidence this has or will work.

The accord presents a chance to fix some of these issues. The Innovative Research Universities lobby group is among those and suggesting we need to rebalance what domestic students contribute to their studies.

This is particularly important, as many groups are still underrepresented in higher education, including First Nations people and those from regional Australia.

Many academics have tenuous careers

But reevaluating what students pay, and the Job-ready Graduates policies, is only one challenge for the accord. To ensure that students receive the best education, we need to ensure universities have the best workforce possible.

There is discontent and more than a little trauma within academic and professional staff ranks after two years of the pandemic and huge challenges, such as shifting university education online.

On top of this, much of the university workforce is employed on short-term and casual contracts. Australian higher education risks losing some of its best and brightest who decide they can no longer put up with such precarious employment.

The anger over pay and conditions is shown in recent strike actions around the country.

International education

One of the biggest issues the Accord will need to grapple with is the future of international higher education in Australia. Before COVID, there were more than 580,000 international students in the country.

International students are returning to Australia, but they are mostly going to more prestigious universities


It says a lot that so many have been willing to come here as most had options to study in other countries. The fees these students paid have contributed to the high quality of the Australian sector and funded much of the research. Thinking through how quality research can be supported without these fees is a major challenge for the accord, because we need to be able to future proof the research system.

The key test for the accord will be whether it can facilitate a system that creates the kind of education that is attractive and suitable for all students, whether they are from Australia or overseas.

Trump announces he’ll run for president again as Murdoch turns on him – and it could be politically expensive for both

Source: The Conversation (Au and NZ) – By Rodney Tiffen, Emeritus Professor, Department of Government and International Relations, University of Sydney

No politician, journalist or media critic has ever been heard to utter the phrase “as subtle as a Murdoch tabloid”.

So, when Murdoch’s New York Post responded to the Republicans’ unexpectedly meagre gains in the US mid-term elections, you did not need to read between the lines to see whom they blamed.

The headline was “Trumpty Dumpty” with a picture of an egg-shaped Trump sitting on a wall and the sub-head “Don (who couldn’t build a wall) had a great fall – can all the GOP’s men put the party together again?” This is a reference to the great wall that Trump promised in 2016 to build along the Mexican border to keep illegal immigrants out.

More soberly, Murdoch’s Wall Street Journal editorialised that Trump is the Republican Party’s “biggest loser”, whose campaigning had failed in 2018, 2020 and now 2022.

Trump has now announced he will be a candidate for the presidency in 2024. This suggests the Murdoch-Trump divorce is going to be long and messy, and may be politically expensive for them both.

The Murdoch media relish their reputation as king-makers. In Britain in 1992, after the Conservatives unexpectedly were re-elected, the front page of Murdoch’s Sun proclaimed “It was the Sun wot won it”.

Indeed, Murdoch has been on the winning side of every British election since 1979.

This perfect record is not paralleled in the US or Australia. Murdoch’s support was not sufficient to give Trump victory in the 2020 presidential election or the Morrison government success in 2022, let alone various state elections around Australia.

In Australia, the Murdoch press has been on a downward spiral in its capacity to directly influence election results. There seem to be three main reasons for this.

The first is their declining circulation, which not only has reduced their outreach, but increasingly means their readership comprises disproportionately an elderly constituency already set in their attitudes.

The second is that once Murdoch had a keen populist touch, able to sense coming currents in the public, side with them and make them stronger. But in more recent years his own strong right-wing views have made his media more rigid and less in tune with shifts in public opinion.




Read more:
The January 6 hearings have been spectacular TV, but will they have any consequences for Trump?


The third is that his media have become more crudely propagandistic over the decades. When Murdoch switched sides to Tony Blair’s Labour in the 1997 election, according to the acting editor of the Sun, Neil Wallis, Murdoch told him they were to be 200% behind Blair and everything he did. When he swung back to the Conservatives under David Cameron the news coverage swung at least as strongly in that direction.

In 2013, the Daily Telegraph kicked off its Australian campaign coverage with the injunction to “Kick this mob out”. It was a psychologically ripe moment after the Rudd-Gillard struggles. It is less clear that the anti-Labor campaigns since have been as in touch with the public mood.

Extreme coverage probably energises the base, but may not be terribly effective in swaying swinging voters.

In many ways, it would make commercial and professional sense for the Murdoch media to distance themselves from Trump. The next couple of years are likely to bring a series of controversies focused on Trump and his close allies such as Steve Bannon and Rudy Giuliani.

His business affairs may lead to prosecutions; the fall-out from the January 6 riots will continue in various ways, while there may be other specific charges relating to attempts at vote-tampering.

Moreover, all current support for Trump begins with the palpable lie that he really won the 2020 election. At the very least, support for Trump now is focused more on reclaiming the past than on the present or future.

It is easy to see that the culture war rhetoric of Florida Governor Ron DeSantis may overlap somewhat with Trump’s appeals, but without all of Trump’s baggage, and that this would be a tempting route for Murdoch. Indeed some reports have claimed Lachlan Murdoch has already offered to throw support behind DeSantis.

While such a shift would probably work well with the Wall Street Journal, and the New York Post would still have its range of tabloid appeals, it would be trickier to execute it successfully on Murdoch’s Fox News.

Over the past six years, Fox News and Trump have had one of the closest ever relationships between a political leader and a media organisation in any English-speaking democracy. Many of Fox’s most prominent stars have actively campaigned for Trump and advertised their closeness to him.

Moreover, the Fox audience would be one of the strongest Trump constituencies in the country. It would be very easy to alienate some of them, who may then turn to other right-wing media for more comforting views.

Rain makes coal heavy, slippery and harder to dig up. So what does La Niña mean for this already disrupted industry?

Source: The Conversation (Au and NZ) – By Lurion De Mello, Senior Lecturer in Finance, Macquarie University

As the La Niña weather event wreaks havoc across New South Wales, coal operators are suffering. The Australian coal company Whitehaven is among them – last week slashing its production forecasts after disruption by floods and heavy rain.

The irony of a coal company being hit by extreme weather events was not lost on some. While it’s hard to know how climate change is influencing this La Niña, evidence suggests flood events will become more frequent and intense as the planet warms.

Climate variations cause problems for many industries, and coal is not immune. Wet coal is heavier to transport. And rain can disrupt both mine operations and the transport networks crucial to moving coal and mine workers.

All this comes as coal demand surges, and as pressure mounts for the industry to wind back production to help tackle climate change. So let’s look at what the industry faces in these turbulent times.

Rain on the coal parade

Australia is the world’s second-biggest thermal coal exporter, behind Indonesia. Our shipments mostly end up in Japan, India, Vietnam and South Korea.

Thermal coal is burnt to make electricity. Australia also produces metallurgical or “coking” coal used to make steel.

In recent years, extreme weather in Australia has exposed the coal industry’s vulnerability to climate risk.

Research shows the 2010/2011 Queensland floods affected about 40 of the state’s 50 coal mines, costing more than A$2 billion in lost production.

Climate change will clearly disrupt El Niño and La Niña this decade – 40 years earlier than we thought


Australia is now experiencing more heavy rain thanks to a third consecutive La Niña. It led to floods in Queensland last year that forced the Baralaba North Coal Mine to suspend operations after water affected the mine and access roads. Workers were stood down without pay, prompting anger from the union.

In the NSW Hunter Valley, heavy rain in July this year forced closures to a rail network that connects about 40 coal mines to the Port of Newcastle. Coal export services were suspended and the disruption pushed up coal prices.

Heavy rain is likely to interrupt supply for the remainder of spring and into summer. Last week, Whitehaven said rain and local flooding were affecting production at two open-cut mines near Gunnedah in NSW. Roads were cut off as dams and rivers near the mine spilled over, forcing the company to transport staff to the mine by helicopter.

Rain can bring other problems. Wet coal can slip and spill from conveyor belts while being loaded onto ships. And wet coal is heavy, making it more expensive to transport.

Volatile times for coal

Australian coal exports remain strong. But the rain disruptions add to already unsettled times for coal, both here and abroad.

Demand for coal has increased in the past two years, for a number of reasons. First is the global economic rebound from the COVID pandemic. Second is soaring gas prices following Russia’s war on Ukraine.

Diesel supply issues and upcoming cuts to crude oil production are also driving coal demand.

As the Northern Hemisphere heads into winter, demand is likely to increase further. The United Kingdom, for example, plans to keep coal plants operating this winter, despite a longer-term plan to permanently close them by October 2024. And Asia may have to lean more towards coal for the next six months as liquified natural gas flows into Europe.

All this has pushed coal prices up. So rain-related disruptions to Australian coal exports may result in missed opportunities for our coal operators.

Global carbon emissions at record levels with no signs of shrinking, new data shows. Humanity has a monumental task ahead


At the same time, the coal industry faces headwinds.

Shipping costs have reached new highs. For Australian exporters, China’s ban on Australian coal is an added complication – however this week’s meeting between the two nation’s leaders may have thawed diplomatic relations.

Then, of course, there’s climate change. Coal is the world’s largest source of energy-related carbon dioxide emissions. There’s widespread acknowledgement we must move away from burning coal and transition to renewable energy to avoid the worst climate harms.

Many countries still rely on coal for energy security and for use in industrial processes. Coal also supports jobs and provides export income.

In India, for example, the minister in charge of coal production says the fossil fuel will play an important role in the country until at least 2040. And a study released last month found hundreds of coal companies around the world were developing new mines and power stations.

So moving away from coal – particularly thermal coal – is likely to take time.

Russell Freeman/AAP

What does all this mean?

In the short term, as La Niña hangs around, Australia may struggle to fulfil its coal supply commitments over the Southern Hemisphere spring and summer.

This is likely to add further headaches to the already crunched energy market.

Wet conditions are not the only climate threat to the mining industry. Drought and heat, for example, reduce the availability of water needed to operate mines. And extreme heat can affect equipment, electricity supply and worker productivity.

In the longer term, the prospects for Australia’s coal exports are very uncertain. The Reserve Bank, for example, says coal and gas exports from Australia would at least halve if big buyers including China, Japan and South Korea meet their climate commitments.

There are many types of coal – and challenges abound in replacing them with cleaner alternatives. Until the transition is complete, coal is among many industries that must adapt to future weather extremes.

A new cyber taskforce will supposedly ‘hack the hackers’ behind the Medibank breach. It could put a target on Australia’s back

Source: The Conversation (Au and NZ) – By Mamoun Alazab, Associate Professor, College of Engineering, IT and Environment, Charles Darwin University

The Australian government is launching an offensive against cybercriminals, following a data breach that has exposed millions of people’s personal information.

On November 12, Minister for Cyber Security Clare O’Neil announced a taskforce to “hack the hackers” behind the recent Medibank data breach.

The taskforce will be a first-of-its-kind permanent, joint collaboration between Australian Federal Police and the Australian Signals Directorate. Its 100 or so operatives will use the same cyber weapons and tactics as cybercriminals use, to hunt them down and eliminate them as a threat.

Details on how the taskforce will operate remain murky, partly because it needs to keep this information away from criminals. But the fact remains that taking an offensive stance, while it could deter further attacks, could also put a big red cross on Australia’s back.

Australia punches back

It was only in 2016 that the Australian government first publicly acknowledged it has offensive cyber capabilities housed in the Australian Signals Directorate – and that these are used against offshore cybercriminals. The admission came from then prime minister, Malcolm Turnbull, following attacks on the Bureau of Meteorology and Department of Parliamentary Services.

Australia has used cyber offensive strategies a number of times in the past. This has included operations against ISIS and, more recently, efforts to disable scammers’ infrastructure and access to stolen data at the start of the pandemic. Details of intelligence operations are generally kept under wraps, especially where the Australian Signals Directorate is involved.

How might the taskforce operate?

Minister O’Neil has said the new taskforce will:

scour the world, hunt down the criminal syndicates and gangs who are targeting Australia in cyber attacks and disrupt their efforts.

As to whether the it could launch a counterattack on the Medibank hackers, the resources are there, but working out the kinks will be crucial. Australia’s intelligence agencies have more resources than the average organised cyber gang, not to mention connections to other advanced intelligence agencies around the world.

However, one key issue with holding cybercriminals to account is attribution. A legitimate counterattack requires identifying the source of an attack beyond reasonable doubt. The Medibank data leak has been attributed to criminals based in Russia – most likely from, or at least associated with, the REvil cyber gang.

This assumption is based on similarities between existing REvil sites on the dark web and the extortion site hosting the stolen Medibank data, as well as other similarities between the Medibank attack and REvil’s previous attacks.

What do we know about REvil, the Russian ransomware gang likely behind the Medibank cyber attack?


That said, hackers can hide their identity by routing through (often unaware) third parties. So even if this attack is attributable to REvil, or its close associates, the attackers could easily deny involvement if taken to court.

The group could say its systems were used as unwitting hosts by another external perpetrator. Plausible deniability can almost always be maintained in such cases. Russia (and China) have had a track record of denying involvement in cyber espionage.

As such, it’s very difficult to prosecute cybercriminals – especially in cases where these criminals may be backed (officially or unofficially) by their government. And if perpetrators can’t be put behind bars, they can simply lie low for a while before popping up somewhere else in cyberspace.

Beyond the Medibank hackers, the taskforce will also target other potential threats to Australia. In the case of inaccurate attribution in any of these operations, we might see tit-for-tat escalation. In a worst-case scenario, attacks based on incorrect attribution could start a cyberwar with another country.

Medibank hackers are now releasing stolen data on the dark web. If you’re affected, here’s what you need to know


Defence before offence

By actively seeking and trying to neutralise offshore gangs, Australia will put a target on its back. Russian-linked criminal gangs and others might be encouraged to retaliate and target our sectors, including critical infrastructure.

Boosting Australia’s cyber defences should be the top priority – arguably more so than retaliating. Especially since, even if the taskforce successfully mounts a counterattack on the Medibank hackers, it’s unlikely to recover any data stolen (since criminals make copies of stolen data).

Going after cybercriminals addresses the symptoms of the problem, not the root: the fact that our systems were vulnerable enough to be hacked in the first place. The Medibank breach, and the major Optus breach preceding it, have both demonstrated that even businesses with seemingly strong cybersecurity protocols are vulnerable to attacks.

The best option from a rational and technical standpoint is to prevent, as much as possible, data being stolen in the first place. It might not be as flashy a solution, but it’s the best one in the longer term.

Word from The Hill: Albanese-Xi meeting is the first step on long march

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

As well as her interviews with politicians and experts, Politics with Michelle Grattan includes “Word from The Hill”, where she discusses the news with members of The Conversation politics team.

In this podcast Michelle and politics editor Amanda Dunn discuss the significant thaw in Australia-China relations that’s come with the Albanese-Xi meeting, held on the sidelines of the G20 in Bali. The last such top-level meeting was between President Xi Jinping and then PM Malcolm Turnbull in 2016.

It’s now a question of whether this breakthrough will lead to serious follow-through, with a relaxation of China’s damaging restrictions on a range of Australia’s exports.

Meanwhile next week, the prime minister will be back into the hurly-burly of domestic politics, with the government battling to secure its controversial industrial relations bill through the Senate before Christmas. All eyes are on Senate independent crossbencher David Pocock, from the ACT.

The final sitting fortnight of the year will put the parliamentary stamp on the anti-corruption commission and also see a free vote in the upper house on a bill (already through the House of Representatives) to allow the ACT and Northern Territory to legislate for voluntary assisted dying.

Pumping loud music is putting more than 1 billion young people at risk of hearing loss

Source: The Conversation (Au and NZ) – By Robert Cowan, Professorial Research Fellow, Audiology and Speech Pathology, The University of Melbourne

Music is an integral part of human life. It’s all around us, just like sunshine, lifting our mood. We enjoy it so much that many of us take it with us everywhere on our phones or we spend weekends hitting the club scene, live-music venues or concerts.

Meanwhile, many of us may have felt annoyed by loud sound from music venues or remarked on sound emanating from someone else’s headphones. We’re probably aware we should prevent hearing loss from loud industrial noise at work or from using power tools at home.

A systematic review released today in BMJ Global Health reports unsafe listening practices in adolescents and young adults from using personal listening devices (such as phones or digital music players) and going to loud clubs and gigs are common, and could be a major factor contributing to hearing loss.

In fact, the authors estimate the pumping tunes could be placing up to 1.35 billion young people at risk of hearing loss worldwide.

What the study looked at

Systematic analysis involves looking across multiple studies to identify consistent findings. In this study, the authors included 33 peer-reviewed studies published between 2000 and 2021, involving over 19,000 people, aged 12–34.

In the study, unsafe listening was identified as listening at levels above 80 decibels for over 40 hours per week. For context, this is the level above which most Australian states require industry to implement noise protection processes such as use of hearing protectors.

The study confirms the rate of unsafe listening practices is high in adolescents and young adults: 23.81% of them were listening to music on personal devices at unsafe levels and 48.2% at loud entertainment venues (though this rate is less certain). Based on global estimates of population, this translates to up to 1.35 billion young people at risk of hearing loss globally. The World Health Organization estimates over 430 million people worldwide already have a disabling hearing loss and prevalence could double if hearing loss prevention is not prioritised.

The results tally with our previous studies conducted by Australia’s National Acoustic Laboratories and HEARing Cooperative Research Centre.

More than a decade ago we reported a high potential for hearing loss from attendance at nightclubs, pubs and live concerts in young Australians aged between 18–35 years.

Back then, we found 13% of young Australians (aged 18–35) were getting a yearly noise dose from nightclubs, concerts and sporting activities that exceeded the maximum acceptable dose in industry. In 2015, the WHO launched the Make listening Safe initiative to encourage young people to protect their hearing.

Why it’s bad for your hearing

So what’s the problem with loud music? Like sunshine, overexposure can lead to harm.

Loud noise, including music, can kill off hair cells and membranes in the inner ear (the cochlea). Once hearing is lost, a person mightn’t be able to hear or understand speech or sounds around them.

Research shows hearing loss results from a combination of sound being too loud (and it doesn’t need to be painful to cause hearing damage), listening to loud sound too long (and the louder the sound, the less time you can listen before your hearing is at risk) and how often you are exposed (and hearing damage is cumulative over time).

A good “rule of ear” is that if you hear ringing in your ears at or after listening, you are at risk of damaging your hearing. This type of hearing loss is permanent and may require use of hearing aids or cochlear implants.

Don’t wear earphones all day – your ears need to breathe


Wait, so no loud music at all?

So what can we do, short of throwing away our headphones and avoiding clubbing and live music?

First, just like with the sun and skin, we need to be aware of the risks to our hearing and take the necessary steps to protect ourselves. We need to be aware of how loud sound is around us and how to keep our exposure within safe levels. We can do this by using personal hearing protection in clubs (such as ear muffs or ear plugs that are fit for purpose), or limiting how often we visit noisy music venues or how long we stay at really loud ones.

In Australia, people can access a free noise risk calculator to calculate their personal risk using an online sound level meter, and to explore how changes in lifestyle could protect their hearing while still allowing them to enjoy music.

Most phones now comes with software can monitor safe listening levels and limit exposure.

Hearing protection at the venue level is more challenging and may require regulatory and industry-based approaches. Our 2020 research identified hazard controls for entertainment venues, such alternating volume between louder and softer levels, rotating staff, providing quiet rooms, and raising speaker locations above head height. We also showed DJs and venues were open to initiatives aimed at reducing the risk of hearing loss for their patrons and staff.

Compromises are possible and they could enable enjoyment of music at live-music venues, while still protecting hearing. That way everyone will be able keep enjoying music for longer.

Missile hits Poland, killing two: is this the trigger for a wider European war?

Source: The Conversation (Au and NZ) – By Matthew Sussex, Fellow, Strategic and Defence Studies Centre, Australian National University

Twitter/@Visegrad24

One of the most persistent fears about Russia’s invasion of Ukraine in February 2022 has been the potential for the war to ramp up dramatically in scope.

Those fears are legitimate, especially given the bellicose rhetoric and brinkmanship emanating from the Kremlin. And although concerns about nuclear escalation have dominated the headlines, the surest path to a bigger war would be an attack – inadvertent or otherwise – on a NATO state. If NATO members were drawn in, that would bring about what Kremlin propagandists have been spruiking for months: an existential contest between Russia and the European West.

Now a large explosion has killed two people in the Polish village of Przewodów, close to the Ukrainian border. It occurred during a massive Russian bombardment, with around 100 missiles fired at civilian and infrastructure targets across Ukraine.

Is this the tipping point that dramatically changes the contours of the war?

For the moment, that seems unlikely. But it is a significant crisis with the potential to spiral further, and it will require careful management to avert that.

Does this mean the war is widening?

That an attack on a NATO country might not automatically trigger a collective response by the alliance seems to run contrary to popular wisdom. After all, doesn’t Article 5 of the NATO Treaty clearly state that an attack against one member is an attack against all of them?

It was certainly the case that Article 5 was invoked after the September 11 attacks on the US in 2001. So what’s different here?

For one thing, details about the explosion are still sketchy. It could have been a Russian missile (or missiles) that wandered off-target. It also could have been a Russian strike, perhaps intended for power generation stations near the west Ukrainian city of Lviv, that was knocked off course by Ukrainian air defences.

Indeed, there is some preliminary evidence that missile fragments bear close resemblance to the Russian-made S-300 surface-to-air systems used by Ukraine to knock down incoming cruise missiles and enemy aircraft.

Why Putin’s retreat from Kherson could be his most humiliating defeat yet


Even if that is the case, it’s worth remembering that nothing would have happened if Russian forces hadn’t been enthusiastically shooting missiles at Ukraine in the first place.

It’s also important to note that Article 5 isn’t black and white. Indeed, having flexibility and room for interpretation is probably a good thing in this case. Poland is highly likely to invoke Article 4 of the treaty, requesting an urgent meeting of the alliance to report an attack on its territory.

Warsaw may well push for an Article 5 response at that meeting, seeking collective action from the alliance. But that response can be graduated up to and including military force. It is not an automatic trigger for it.

Poland, led by President Andrzej Duda, has invoked Article 4 of the NATO treaty to ask other member states to discuss further action.

For its part, the Kremlin and its obedient media have predictably trotted out a number of bizarre claims. The main line seems to be that the missile was a deliberate attack by Ukraine to draw NATO into the conflict, although Russia Today’s chief propagandist Margarita Simonyan has wildly speculated that it was a British missile, or that Poland attacked itself to bring about a larger war.

These can all safely be discounted as false flags intended mainly for a domestic audience. Nobody but the most ardent Putinverstecher (German for “Putin sympathiser”) in the West will believe them. There is certainly no incentive for Ukraine to jeopardise its vital armaments lifeline with the West with a preposterously risky gambit to make NATO a combatant.

On the contrary, Ukraine’s armed forces are doing just fine without NATO involvement. The string of humiliating Russian defeats, up to its most recent retreat from Kherson, has demonstrated that very clearly.

Could Russia collapse?


So what is NATO likely to do?

A range of options will be on the table. NATO’s response will need to be carefully calibrated to ensure it is seen as acting decisively but not provocatively. That may seem overly cautious given it was a NATO member that has suffered an attack, but Western military planners will be keen to avoid feeding Kremlin conspiracy theories about NATO being a de facto combatant.

At the same time, the West will want to demonstrate to Russian President Vladimir Putin that it will not tolerate death and destruction on the territory of NATO members as a result of a war that Putin bears the sole responsibility for starting.

And, finally, the NATO response will need to satisfy Warsaw to maintain alliance confidence: particularly since its leaders, including US President Joe Biden, have gone on record with statements committing them to the vigorous defence of NATO members. Indeed, the credibility of the West – that it stands by its friends and honours its commitments – is just as important for how it is perceived beyond Europe as within it.

To achieve that, NATO will clearly need to do more than just issue a strongly worded protest note, along with additional sanctions on Russia. These may ultimately be part of the response package, but there will also be pressure for more concerted action, such as increasing NATO’s military presence in Poland and performing more combat patrols.

That would be a measured response, and it would be consistent with NATO’s geopolitical trajectory since the war began, with Warsaw now assuming a prominent place among the alliance’s members.

There are also other steps that are likely to be considered. For some time, Ukraine’s President Volodymyr Zelensky has been requesting advanced air defence systems from the West. He is now likely to get them. At the very least, this episode will strongly bolster his arguments that Ukraine deserves the means to protect its citizens.

What about other measures? Is it now the time, for instance, for NATO to enforce a “no-fly zone” in Western Ukraine? Perhaps. Earlier in the war, the idea was rejected as too escalatory and difficult to manage, especially since safeguarding humanitarian corridors for refugees were also part of the discussion.

But with the tide of the war turning in Ukraine’s favour, NATO’s more risk-averse members might endorse a limited use of air defences against Russian missile strikes that are targeted close to Ukraine’s borders with NATO states. Conversely, of course, NATO’s leaders might deem that a step too far at a time when Ukraine is winning the war in any case.

For Putin, though, some degree of NATO response is now inevitable. Being able to bluster once again about Russia’s struggle against a satanic and morally bankrupt West is unlikely to bring him any comfort. His indiscriminate missile strikes have been laid bare as a tactic of the weak. They will harden Western resolve and make its leaders far less inclined to put pressure on Kyiv for a negotiated settlement.

And they will hasten the moment when Putin finally learns a core lesson about wars: those who start them only rarely emerge as victors.

How superblocks can free up and improve CBD space for the people of Melbourne – a step-by-step guide

Source: The Conversation (Au and NZ) – By Marco Amati, Associate Professor of International Planning, Centre for Urban Research, RMIT University

frontispiece

For 185 years, Melbourne’s Hoddle Grid – the ordered layout of CBD streets and blocks designed in 1837 – has dictated the flow of people and vehicles in the city centre. But how well does the grid serve 21st-century needs?

Melbourne faces three interconnected challenges that conflict with a business-as-usual, car-based grid. These are: how to end the dominance of cars; how to respond to the reality of the city centre as a residential area; and how to “reignite” post-pandemic activity in the CBD.

Superblocks are an approach, pioneered in Barcelona, to making urban areas more liveable and people-friendly.

A superblock covers an area of multiple city blocks – typically nine in a 3×3 format – that excludes through traffic. In this space, cyclists, walkers and residents have priority, though cars still have low-speed access to all buildings within the area. Superblocks transform formerly car-dominated streets into public spaces that can be used for a range of activities.

We have developed a step-by-step approach to introducing superblocks to Melbourne.

Colonialism lives on rent-free in our cities

The Hoddle Grid was used an instrument of power for expropriating land from peoples of the Eastern Kulin nation. It asserted formal control over lands that John Batman had acquired illegally.

The array of regular blocks would have helped with selling land to distant speculators by signalling equality among bidders, military control and efficient circulation of people and air.

For much of the 20th century, the grid has been open to vehicle through traffic. More recent developments have given nods to pedestrians, laneways and liveability.

Over 60% of street space in the grid is still given over to cars, although these account for less than 10% of all trips within the grid. As a result, it is still a significant site of injury, involving both road crashes and colonial dispossession.

While the grid has remained conceptually stuck in the late 19th and early 20th centuries, the central business district, despite its name, has become a residential area. Promoted by the Postcode 3000 project in the 1990s, there was a shift from a “doughnut city” – populated suburbs around a hollow centre – to a cafe society.

The city centre went from 750 registered residential units in the early 1980s to more than 96,000 today. This spurred a rise in the number of bars, cafes and restaurants.

To reshape the city centre in ways that better meet the needs of Melburnians now and in the future, the grid must be redesigned. It is time, in the words of Canadian scholar Vanessa de Oliveira Andreotti, to “wake up, smarten up, step up, own up, clean up, grow up, and show up”.

How can superblocks improve the grid for people?

But how can superblocks be applied in car-dominated Melbourne? A staged and bespoke approach to gathering information and planning routes is needed. We suggest the following steps.

1. Audit the grid

Hoddle’s innovation was to have a mixture of little and main streets running parallel to one another. As a result, the sizes of junctions vary.

As well as assessing the locations of junctions and what they are like, in Melbourne we must also consider tram routes.

2. Work out what configurations are needed and where

The rectangular form, mix of large and little streets, tram lines and existing pedestrian areas all suggest departures from the “classic” 3×3 superblock that looks like a hashtag. We’re looking at including some 2×3 superblocks. All these forms should be considered to increase and improve space for pedestrians.

We propose four different options. In the following maps the green dots are junctions that have been made highly accessible for pedestrians. The more green dots, the better.

Map showing the largest number of superblocks for Melbourne
Option 1: Yields the largest number of superblocks by rerouting traffic along the roads with tramways. This involves sending traffic down Bourke Street Mall and rerouting Swanston Street trams along Russell Street.
Map: Alexia Yacoubian and Mónicá Suarez
Option 2 with less green dots and superblocks
Option 2: Yields fewer green dots and maintains the Bourke Street pedestrian mall, but moves the Swanston Street tram line to Russell Street.
Map: Alexia Yacoubian and Mónicá Suarez
Option 3: a more conservative proposal that works around the current pedestrianisation of Bourke and Swanston streets and maintains the tram where it is.
Option 3: A more conservative proposal that maintains current tram locations. However, in a superblock plan the centre junctions should not be a location for movement.
Map: Alexia Yacoubian and Mónicá Suarez
Map of the most conservative approach, leaving everything as is and include trams in the superblocks
Option 4: Acknowledges that some junctions may have to include trams in the centre of the superblock.
Map: Alexia Yacoubian and Mónicá Suarez

3. Assess the success of different options

Option 1 above increases the area of footpaths from around 169,000 square metres to 385,480 square metres – an increase of around 11 MCGs.

Map showing existing footpaths with an area of 169,076 square metres.

Map: Alexia Yacoubian and Mónica Suárez using data from City of Melbourne
Map showing the footpaths in green
Option 1 produces a 2.3 times increase in footpath space and greater pedestrian connectivity.
Map: Alexia Yacoubian and Mónicá Suarez

Placing open spaces in junctions radically changes the pedestrian experience. Using a method from ecology, we can calculate a pedestrian connectivity index – the probability that a pedestrian can get from one point on a footpath to another in the grid without crossing a road. For the current grid, the probability is 0.2%. For the superblock model, it’s 4% – a 20-fold increase.

Even though pedestrians have more access, unlike a pedestrianisation plan, vehicle access to the buildings remains largely the same.

4. Decide how to use all this new open space

Once the questions shift from a matter of “if” to “how”, other questions come into play. What to do about car parking? We know off-street garages within 200 metres of on-street car parks could accommodate half of this parking.

How can these new spaces in junctions be used? The renderings below (by Mónica Suárez and Alexia Yacoubian using Google Street View images) provide some ideas. The first shows a “green dot” space where a car-only junction has been converted to pedestrian space. The second shows a “yellow dot” junction shared by trams and pedestrians.


Before and after: corner of Exhibition and Little Lonsdale streets


Before and after: corner of Swanston and Lonsdale streets


These are pilot ideas – e.g. the discussion should continue to how the grid interacts with surrounding streets and with Birrarung. But it could also act as a template for other cities in Australia that are similarly modern, colonial and grid-based.

5. It’s a marathon not a sprint

For more than 30 years, cities around the world from Curitiba to Barcelona have in effect been saying: thank you, dear car, for all you have given us in the 20th century, but now it is time to move on.

In practice, this needs to be a gentle and caring process with many steps, learning as we go. It is as de Oliveira Andreotti might argue, low-intensity activism and a marathon rather than a sprint.

Urban planning is now on the front line of the climate crisis. This is what it means for our cities and towns

Source: The Conversation (Au and NZ) – By Barbara Norman, Emeritus Professor of Urban & Regional Planning, University of Canberra

International climate talks in Egypt known as COP27 are into their second week. Thursday is Solutions Day at the summit. Recognising that urban planning is now a front-line response to climate change, discussions will focus on sustainable cities and transport, green buildings and resilient infrastructure.

The COP26 Glasgow Pact expects countries to update planning at all levels of government to take climate change and adaptations into account. Urban planning is also included in the most recent report by the Intergovernmental Panel on Climate Change (IPCC).

The Australian Royal Commission into National Natural Disaster Arrangements similarly reinforced the urgency of planning for climate change. Its report recommended making it mandatory for land-use planning decisions to consider natural disaster risks.

Australian communities have been through a series of recent disasters. We have had extremes of drought, bushfires and now storms and floods. Some towns have been evacuated repeatedly.

Beyond a state of sandbagging: what can we learn from all the floods, here and overseas?


Land-use planning needs to be updated to respond to a changing climate. This means working with nature, involving communities and, importantly, including the tools needed to plan for risk and uncertainty. Examples include scenario planning, carbon assessments of developments, water-sensitive urban design and factoring in the latest climate science into everyday decisions on land use.

We can’t avoid the issue of resettlement

Climate-driven resettlement, in my view, will be one of the most significant social challenges of this century. The IPCC estimates that “3.3 to 3.6 billion people live in contexts that are highly vulnerable to climate change […] unsustainable development patterns are increasing exposure of ecosystems and people to climate hazards”.

The costs are staggering. The OECD estimates, for example, that in the past two decades alone, the cost of storms reached US$1.4 trillion globally.

In my review of recent climate-induced resettlement around the world, two important lessons are:

  1. it must actively involve the community

  2. it takes time.

The relocation of houses in Grantham, Queensland, is a positive example of resettlement. The repeated floods across eastern Australia – and the Black Summer bushfires of 2019-20 – show why a national conversation with urban and regional communities on this very challenging issue needs to start very soon.

What are the essential actions for planning?

Based in part on interviews with urban leaders around the world for my new book, Urban Planning for Climate Change, I have put forward ten essential actions. Particularly relevant to Australia are the following actions:

  • map the climate risks and overlay these on existing and future urban zones to identify the “hot spots” – then publicly share the data

  • make it mandatory to consider natural disaster and climate risks in all land-use planning decisions for new development and redevelopment

  • plan for the cumulative impacts of climate change on communities and their consequences – this includes planning resettlement with those at risk

  • provide an inclusive platform for community conversations about carbon-neutral development and adaptation options – such as climate-resilient housing and smart local renewable energy hubs – together with up-to-date, accessible information on predicted climate risks so communities and industry can make informed decisions

  • invest in strategic planning that integrates action on carbon-neutral development and climate adaptation. Do not build housing any more on flood-prone land or areas of extreme fire risk.

The outcome must be that policymakers and the public have a clear understanding of where the risks are, where to build, where not to build, and the range of options in between.

For example, not building on the coastal edge does not mean quarantining that land. It means allowing activities, such as recreation, that can withstand increasing coastal flooding, as well as coastal-dependent uses such as fisheries and coastal landscapes designed to absorb storm surges.

Floods are natural, but human decisions make disasters. We need to reflect on the endless cycles of blame


What are the next steps for Australia?

Architects, engineers, planners and builders around the world are working with communities to make development more sustainable. They need support from all levels of government.

To better plan for climate change, we in Australia can take a few key steps:

1. Update the 2011 National Urban Policy

An updated national policy should incorporate the latest climate science, national emission targets, energy policies and adaptation plans. This will help ensure new development, redevelopment and critical infrastructure are designed and built to be carbon-neutral and adapt to a changing climate.

2. Audit planning at all levels to ensure it considers climate change

The federal government should host a meeting of state and territory planning and infrastructure ministers as soon as possible after COP27. Climate change needs to be a mandatory consideration in all future land-use planning. The ministers should commission an audit of all planning legislation and major city and regional centre plans to ensure this happens.

Engagement with wider industry will be important to ensure effective implementation. Partnering in demonstration projects that showcase affordable, climate-resilient urban development can help promote the uptake of leading practice. Examples range from affordable retrofitting of housing with renewable energy solutions to recycled building materials and heat-reducing landscaping.

Extending this approach to whole neighbourhoods and suburbs is the next step.

3. Engage with the region

The federal government should continue its positive first steps on climate change with our regional neighbours, including Indonesia, New Zealand and Pacific Island nations. This long-term work needs to include support for developing climate-resilient towns and cities, as well as for resettlement.

We can learn from each other on this challenging pathway, which will connect us more than ever as a region.

NZ’s first climate adaptation plan is a good start, but crucial questions about cost and timing must be answered


4. Ensure all levels of government work together on strategic funding

Funding is needed to develop climate-resilient plans for communities across Australia. This will help minimise future impacts and ensure we are building back better now and for future generations.

Most of the developments being approved today will still be here in 2050. This means these developments must factor in climate change now.

We now have a national government that is committed to action on climate change, thank goodness. Much is being done on renewable energy and electrification of the transport system. It is time to turn our attention to making our built environment more climate-resilient.

Humans are going back to the Moon, and beyond – but how will we feed them?

Source: The Conversation (Au and NZ) – By Kim Johnson, Senior lecturer, La Trobe University

NASA JSC/Meghan McArthur

NASA’s Artemis I launch is a major step forward in humans going deeper and spending longer in space than ever before.

Future Artemis missions plan to take crew to the Moon and eventually Mars, which is likely to be a three-year round-trip.

But what will the astronauts eat? There are only so many protein bars and vitamins one can tolerate and survive on for years on end.

Plants are the basis of life on Earth with their amazing ability to convert light, water and carbon dioxide (CO₂) into food, and are the logical solution to support humans in space.

The challenges of a space garden

Astronauts have already eaten space radish, chilli peppers and lettuce grown on the International Space Station, and having freshly grown veggies in microgravity can support health and wellbeing. But there are a number of challenges in growing a flourishing space garden.

Space environments are CO₂-rich, lack soil microbes, have altered gravity, are exposed to potentially harmful solar radiation, and need to use recycled, high-salt water. For plants to thrive in space and offer the full range of nutrients for human health, they need a redesign.

After months of freeze-dried or prepackaged space food, imagine going to your space garden, picking a ripe juicy tomato and spicy chilli to add to your tacos. Adding fresh produce has been a good way to improve astronaut wellbeing, supply essential vitamins and minerals, and add variety and flavour, especially as low-gravity environments affect our taste and smell.

A renewable source of fresh food is essential to future long-term space missions, to avoid astronauts experiencing “food fatigue”, malnutrition and weight loss.

Space plants are currently grown in closed boxes with low energy LED lights, porous clay “soil” with water, nutrients and oxygen supplied to roots; high-tech sensors and cameras monitor plant health. Plants did not evolve to grow in a box and use energy and resources in readiness for changes in light, temperature and disease, limiting full growth potential.

So there is great opportunity to adapt plant genetics to produce faster-growing “pick and eat” food crops such as tomato, carrot, spinach and strawberry designed to reach their maximum potential in closed, controlled environments.

A sustainable space plant future

Future plant growth systems for space will need to be entirely sustainable. That means working alongside all the other systems on a space station or a lunar/Martian base, recycling water and nutrients.

All plant parts will need to be food, compost or converted into useful products such as fuels and plastics. Human waste, including urine, offers a nutrient source for plants, yet they also need to be able to cope with this salty water supply. However, there’s one plant that could be particularly suited to the task.

Duckweed may not be available at your local supermarket, but this very fast-growing plant could be in all space gardens thanks to its ability to thrive in recycled water and be zero waste, with the whole plant being eaten.

Duckweed doubles its weight in just two days, is harvested continually, and is high in protein, nutrients, antioxidants and vitamins. Only a few essential elements (such as vitamin B12/D) are missing that could make it a reliable base source for complete human nutrition.

Duckweed is an incredible, radiation-fighting astronaut food – and by changing how it is grown, we made it better


Recent technical advances in genome editing, gene regulation, and methods to analyse nutrients can be harnessed to adapt duckweed and other plants for optimal growth, minimal waste and complete nutrition.

New plants developed in this way can contain proteins perfectly balanced for human digestion and use, healthy plant oils for an energy boost, and soluble fibre for better gut and cardiovascular health.

Striving to explore space has brought us thousands of innovations we use in everyday life. We can expect that inventions we come up with to support humans thriving in space will deliver multiple and essential sustainability benefits to Earth, especially to on-demand supply of nutrition and biomaterials. Experts across the globe are working together toward these dual goals, including plant biologists, engineers, food chemists, psychologists, sensory experts, nutritionists, ethicists, and legal experts.

A new frontier of human achievement is on the horizon – humans will soon not only be looking up to the night skies in wonder, but also travelling to those destinations beyond our own atmosphere, and in so doing planting seeds of a new way of life on Earth and beyond.

What can we expect from this latest COVID wave? And how long is it likely to last?

Source: The Conversation (Au and NZ) – By James Wood, Associate Professor, epidemiological modelling of infectious diseases, UNSW Sydney

Australia is now mid-way into its fourth wave of COVID in the Omicron era, driven by a rich soup of Omicron descendants. Unlike previous waves, where a single new variant of SARS-CoV-2 variant such as BA.2 or BA.5 was responsible, we have had an explosion of new variants such as XBB.1, BQ.1.1 and BR.2.1.




Read more:
From Centaurus to XBB: your handy guide to the latest COVID subvariants (and why some are more worrying than others)


However, despite this apparent diversity, these new variants all follow a similar script, where the same set of changes have evolved independently across multiple variants. This is called convergent evolution.

These changes make the virus better at infecting people with immunity to existing variants. Since mid-October, the subvariants’ ability to escape immunity from vaccination and/or previous infection has been potent enough to cause a new wave in Australia.

The graph below shows the series of 2022 waves, with the original Omicron the first wave, followed by the double-bump BA.2 (where Western Australia had different timing), the winter BA.5 wave, and now a new upswing in November.


Johns Hopkins University CSSE COVID-19 Data, CC BY

In some good news, this wave is likely to be a shorter and smaller version of the BA.5 wave. Here’s why.

Cases are rising rapidly

In Australia, the wave is already growing rapidly, with indicators such as recorded cases and hospital occupancy showing significant increases in multiple states over the last two weeks.

New South Wales reports on the trend in the underlying variants, with a clear shift since early October.

Removal of mandatory reporting and isolation has led to fewer rapid antigen tests (RATs) being reported. So we may only be recording a smaller fraction of all community infections now than in previous waves.

Previous COVID infection may not protect you from the new subvariant wave. Are you due for a booster?


In the graph below, I’ve used the EpiNow2 R package (an open-source estimation and forecasting tool) to calculate the trend in the effective reproduction number (Rt) using NSW case data since early September.

Rt represents the average number of people that a single COVID case infects at a given point in time. Epidemics decline when Rt is less than 1, while epidemic growth becomes likely once Rt is above 1 and is increasingly steep as Rt rises. This is now substantially above 1 in New South Wales:

Will the wave peak by Christmas? Lessons from Singapore

I think the most likely outcome is the wave will peak by Christmas. In my own work for NSW Health, I am currently projecting a peak in NSW for the first week of December.

But these predictions are uncertain because it is still difficult to estimate the level of protection against infection in our population, despite impressive near real-time laboratory science that is helping to characterise this.

Fortunately, despite the challenges with modelling, the recent Singapore wave can guide our expectations. Caused by XBB.1, this wave was short and sharp, peaking around October 18 and then dropping back almost to pre-wave levels by November 12.

XBB and BQ.1: what we know about these two omicron ‘cousins’


Singapore has also seen a significant increase in hospitalisations, primarily in people aged above 70.

However cumulative cases, admissions and deaths are tracking to be about half those of their BA.5 wave, with no signs of increased severity.

Despite the ability of XBB.1 to evade vaccination and/or previous infection, in Singapore people with prior Omicron infections were about 75% less likely to test positive in this wave than in people without recorded prior infections.

Singapore has also had quite a similar COVID pandemic experience to Australia in terms of restrictions, vaccination and infection waves. One exception is that mask-wearing remains more prevalent in Singapore.

We should, however, expect some differences. Australia has about six times the resident population of Singapore with widely separated population centres. This might mean the wave duration across Australia is one to two weeks longer.

Australia also has a higher proportion of the population above 75, a large fraction of whom haven’t had COVID this year and therefore won’t have hybrid immunity (from both vaccination and prior infection). This could result in more hospital admissions and deaths per capita than in Singapore.

But in general, the Singapore wave supports the prediction this fourth Australian wave of 2022 will peak in early December and fall back below current levels by Christmas.

Is this the new normal? What can we expect in the years to come?

Beyond this year, I’m encouraged by the shift in pattern from single variants causing waves to the evolving variant soup. This evolution has been very rapid recently but there are signs this may slow considerably in 2023.

Firstly, the rate at which mutations occur is proportional to how much virus is circulating. The enormous number of COVID infections across this year mean that in 2022 this change has happened quickly but with each wave getting smaller, this rate of change should slow.

The recent variant soup evolution may also be a positive sign. The different variants in the soup have all gained a transmission advantage following the same immune-escape strategy. The set of relevant mutations were in fact predicted in advance by researchers at the University of Washington.

If you are infected with one of these new variants, you should also have strong protection to the rest of the soup. The absence of big mutational jumps in dominant variants suggests SARS-CoV2, the virus that causes COVID, may now be entering a period of slower, more continuous evolution. This is what we see for seasonal influenza.

COVID has been full of surprises but the evidence suggests we could see SARS-CoV-2 infections fall below our recent trough levels in 2023 and the beginning of a more seasonal pattern to COVID waves.

Countless reports show water is undrinkable in many Indigenous communities. Why has nothing changed?

Source: The Conversation (Au and NZ) – By Bradley J. Moggridge, Associate Professor in Indigenous Water Science, University of Canberra

Tap water in more than 500 remote Indigenous communities isn’t regularly tested and often isn’t safe to drink, according to a water industry report released last week. In some communities, drinking water contained unacceptable levels of uranium, arsenic, fluoride and nitrate.

While these findings are dire, they aren’t news to us. There have been myriad reports over the years on the poor status of safe drinking water in Australia’s remote communities all pointing to inequity of essential services with implications for health. But little has been done to rectify this.

Safe drinking water is a basic human right, no matter where people live. First Nations communities have campaigned for decades for clean water on their Country. As Alyawarre Elders, Jackie Mahoney and Pam Corbett, from Alpurrurulam community in the Northern Territory explained during the report’s launch:

That’s why we’re fighting for this water. It’s not only for us, it’s for them too […] For our old people who fought before us and our kids’ future.

A bureaucratic inquiry cycle

The new report, by Water Services Association of Australia, is the latest to detail this ongoing health crisis. Water can be both unsafe to drink (unpotable) and unacceptable to drink due to taste, colour and feel (unpalatable).

Its findings are consistent with a report by the Western Australian Auditor General last year. It found 37 communities had an unfit drinking water supply due to contamination by microbes (bacteria and viruses), nitrates or uranium – and there had been no improvement since the issue was reported in 2015.

Similarly, a research paper published earlier this year found drinking water supplied to 25,000 people in 99 small communities in 2018-19 didn’t pass Australian guidelines.

Numerous other reports have delivered similar findings. For example, a report in 1994 by the Australian Human Rights Commission examined ten communities and the condition of water and sanitation services, highlighting specific areas of concern.

In 2018, a review of Australia’s progress on the United Nation’s Sustainable Development Goals confirmed that many remote communities don’t have the same level of access to water and sanitation services as urban centres, with flow-on effects to human health.

And in 2020, a Productivity Commission report proposed new objectives to deliver safe and reliable drinking water in remote communities, noting the additional stressor of climate change.

These earlier reports show the drinking water crisis was identified decades ago. Last week’s report reveals not much has changed.

Not every tap delivers safe water

The reasons for undrinkable water in remote communities are multiple and interlinked. We can group them into four broad areas.

The first is physical. This is when the original water source (from the surface or groundwater) may be contaminated with excess levels of chemicals, such as agricultural or industrial chemicals.

The water may also have biological contaminants due to hot weather or faeces from birds and other animals, increasing microbial growth.

And freshwater may become contaminated with salt as the sea level rises and affects natural freshwater wells. This is a major issue for some Torres Strait islands.

The second issue is technical. Local water operators are located remotely, and don’t always get appropriate resources, training and support.

Third, there are financial issues. It’s very expensive to deliver essential services, including water, to remote community councils within large states. For example, in Queensland’s remote Indigenous councils, these services are typically funded sporadically via short-term grants.

Some remote Australian communities have drinking water for only nine hours a day


The final issue is social and governance. Water needs and practices on a cultural level are often poorly understood by service providers.

For example, during the recent drought, severe water restrictions left remote communities without treated and accessible water for hours on end, every day. This not only limited water available for drinking, but also for cultural events such as sorry camps (when the community mourns a loss).

A system that’s fit for purpose, place and people

A feature of successful sustainable water in remote communities is to tailor initiatives for each location. Such initiatives would be shaped by available local staff, water sources, cultural and governance structures and types of pollutants.

All external partners should aim to build long-term working relationships with the communities to avoid the “new face syndrome”. This is a common experience where different representatives visit communities without consistency, inhibiting long-term and trusted working relationships.

Sufficient funding will also be crucial for ongoing, sustainable delivery, with the ambition that water quality is the same as urban supplies.

And additional stressors, especially water insecurity due to climate change, need to be incorporated into water supply and related energy and sanitation planning.

Importantly, all remote essential service delivery and management actions, including water, need to be undertaken collaboratively. They should be led and authored by First Nations researchers, and draw from community strengths and knowledge wherever possible.

This shifts water service efforts being for communities, to being with communities. Indeed, cultural sensitivity and guidance is essential to ensure mutual respect and learning forms the basis of all supply delivery.

IPCC reports still exclude Indigenous voices. Come join us at our sacred fires to find answers to climate change


In keeping with this cultural awareness is an action-based commitment by water suppliers to develop and thoroughly implement “Reconciliation Action Plans”. These are plans in organisations aimed at embedding meaningful actions to advance relationships, respect and opportunities with Aboriginal and Torres Strait Islander peoples.

These plans should include Indigenous-led, co-designed solutions throughout the process. They should be achievable and place-based, however challenging that may be for water utilities and organisations.

Walking the talk

The Water Services Association of Australia’s report was launched by Minister for Indigenous Australians Linda Burney in Parliament this month. This was a powerful call to action on safe drinking water for all Australians to protect health, uphold human rights and implement sustainable development.

It is the responsibility of water service providers and their industry advocates to step up beyond their Reconciliation Action Plan obligations and “walk the talk” to collaborate with communities.

Let’s hope the next report on remote drinking water provision will describe successful and sustainable outcomes.

Climate change will clearly disrupt El Niño and La Niña this decade – 40 years earlier than we thought

You’ve probably heard a lot about La Niña lately. This cool weather pattern is the main driver of heavy rain and flooding that has devastated much of Australia’s southeast in recent months.

You may also have heard of El Niño, which alternates with La Niña every few years. El Niño typically brings drier conditions to much of Australia.

Together, the two phases are known as the El Niño-Southern Oscillation – the strongest and most consequential factor driving Earth’s weather. And in recent years there has been much scientific interest in how climate change will influence this global weather-maker.

Our new research, released today, sheds light on the question. It found climate change will clearly influence the El Niño-Southern Oscillation by 2030 – in just eight years’ time. This has big implications for how Australians prepare for extreme weather events.

A complex weather puzzle

The El Niño-Southern Oscillation occurs across the tropical Pacific, and involves complex interplays between the atmosphere and the ocean. It can be in one of three phases: El Niño, La Niña or neutral.

During an El Niño phase, the central and eastern tropical Pacific Ocean warms significantly. This causes a major shift in cloud formation and weather patterns across the Pacific, typically leading to dry conditions in eastern Australia.

During a La Niña phase, which is occurring now, waters in the central and eastern tropical Pacific Ocean are cooler than average. The associated changes in weather patterns include higher than average rainfall over much of Australia.

When the oscillation is in the neutral phase, weather conditions hover around the long-term average.

Previous research has suggested El Niño and La Niña events may vary depending on where in the tropical Pacific the warm or cold ocean temperatures are located.

But climate change is also affecting ocean temperatures. So how might this play into El Niño and La Niña events? And where might the resulting change in weather patterns be detected? These are the questions our research sought to answer.

3 things a climate scientist wants world leaders to know ahead of COP27


What we found

We examined 70 years of data on the El Niño–Southern Oscillation since 1950, and combined it with 58 of the most advanced climate models available.

We found the influence of climate change on El Niño and La Niña events, in the form of ocean surface temperature changes in the eastern Pacific, will be detectable by 2030. This is four decades earlier than previously thought.

Scientists already knew climate change was affecting the El Niño–Southern Oscillation. But because the oscillation is itself so complex and variable, it’s been hard to identify where the change is occurring most strongly.

However, our study shows the effect of climate change, manifesting as changes in ocean surface temperature in the tropical eastern Pacific, will be obvious and unambiguous within about eight years.

So what does all this mean for Australia? Warming of the eastern Pacific Ocean, fuelled by climate change, will cause stronger El Niño events. When this happens, rain bands are drawn away from the western Pacific where Australia is located. That’s likely to mean more droughts and dry conditions in Australia.

It’s also likely to bring more rain to the eastern Pacific, which spans the Pacific coast of Central America from southern Mexico to northern Peru.

Strong El Niño events are often followed by strong and prolonged La Niñas. So that will mean cooling of the eastern Pacific Ocean, bringing the rain band back towards Australia – potentially leading to more heavy rain and flooding of the kind we’ve seen in recent months.

What now?

Weather associated with El Niño and La Niña has huge implications. It can affect human health, food production, energy and water supply, and economies around the world.

Our research suggests Australians, in particular, must prepare for more floods and droughts as climate change disrupts the natural weather patterns of the El Niño-Southern Oscillation.

Our findings should be incorporated into policies and strategies to adapt to climate change. And crucially, they add to the weight of evidence pointing to the urgent need to reduce greenhouse gas emissions to stabilise Earth’s climate.

New study finds Australia’s preschool expansion ‘has not better prepared’ kids for school

Source: The Conversation (Au and NZ) – By Ragan Petrie, Professor, Texas A&M University; Professorial Fellow, The University of Melbourne

Dave Hunt/AAP

Since 2008, Australia has spent more than A$11 billion dollars over ten years to expand government-funded preschool (or kinder in Victoria) for four-year-olds to better prepare children for school.

But as our new study finds, to date, there is no rigorous evidence to suggest this investment was warranted in the first place or that it has paid off.

The case for preschool funding

Almost every policy report arguing for expansion of early childhood education cites the Perry Preschool Project.

This study was a randomised controlled trial in the 1960s that provided high-quality preschool education to 123 (a small sample) low-income, three- and four-year olds at risk for school failure in Michigan in the United States.

A randomised controlled trial randomly assigns participants into an experimental group that receives a treatment or intervention or a control group that does not. Randomisation balances participant characteristics between the groups, so any differences in outcomes can be attributed to the study intervention.

Randomised controlled trials are considered the gold standard for policy evaluation because they provide direct, causal evidence of the effectiveness of a policy.

The Perry Preschool Project found that by age five, 67% of those who attended the program had an IQ above 90, compared to 28% in the non-program group. Almost 80% of the program group graduated from high school, compared to 60% in the non-program group. The program group also performed better on income at age 40.

While the returns to Perry are impressive, it remains unclear how generalisable these returns are to other contexts and populations.

Preschool in Australia

The federal government expanded preschool funding for four-year-olds in 2008 to improve the supply of early childhood services to all children. Since then, it has also billed the program as better preparing children for school.

Victoria is currently rolling out funded preschool to three-year-olds under the argument that “two years are better than one”.

Recently, New South Wales and Victoria announced government-funded preschool would extend to 30 hours a week (from the current 15) for four-year-olds. More than $9 billion is committed over the next decade in Victoria for early childhood education, and NSW has committed $5.8 billion to expand four-year-old education.

‘Greatest transformation of early education in a generation’? Well, that depends on qualified, supported and thriving staff


But this has not been accompanied by randomised evaluations of these universal programs.

A common approach to evaluate programs is to conduct a “before and after” evaluation that relies on statistical methods. These methods compare those who chose to be in a program to those who did not and make statistical adjustments.

This approach is second best because the methods are not designed to provide causal evidence of a program’s effectiveness.

Our study

Despite the large investment, and significant increase in preschool enrolment, school readiness scores have remained flat for more than a decade.

Just over half (55%) of Australian children are developmentally on track to start school, based on the most recent Australian Early Development Census of five-year-olds entering school. In 2009, 51% of children were on track.

Being on track means a child has met development milestones across five important areas of early childhood development. These are:

  • physical health and wellbeing (such as motor skills and energy levels)
  • social competence (getting along with other children and adults)
  • emotional maturity (being kind to others, not having tantrums)
  • language and cognitive skills (interested in books, recognising numbers)
  • communication skills and general knowledge (can tell a story and have knowledge for that age, such as knowing dogs bark or apple is fruit).
Made with Flourish

To understand this issue further, we conducted a population-level analysis of preschool expansion for four-year-olds on measures of child development. That is, we looked at changes in school readiness as four-year-old preschool/kinder enrolment increased.

We used Australian census data on preschool enrolment and Australian Early Development Census data on the five development outcomes, and mapped them to local government areas.

The goal was to see if there is any evidence areas in which preschool has expanded also has improved school readiness. The analysis is not causal, but it illustrates associations at the population level for children who did and did not attend preschool. Plus, it accounts for differences across regions.

Our findings

We found there are no, or negative, effects of preschool on child outcomes.

Areas which had increased preschool enrolment by ten percentage points saw a decrease in school readiness by half-a-percentage point. This implies billions spent with no evidence children are better prepared for school.

Made with Flourish

If we only look at areas outside of Victoria and NSW, the results are worse. The decline in school readiness doubled to a decrease of one percentage point.

Of course, this analysis cannot speak to how school readiness would have evolved without preschool expansion. We do not observe this. The analysis cannot say if children would have been less, similarly or better prepared without investment in preschool.

What we can say is that areas that saw an increase in preschool enrolment did not see a corresponding increase in school readiness, which you would assume from the level of investment. Preschool expansion, as it happened in Australia, has not better prepared kids for school.

More research is needed to determine whether and how to expand preschool offerings.

More evidence needed

We are not arguing governments should not invest in children or their early education.

On the contrary. Evidence exists that high-quality preschools delivered at small scale to targeted groups can have positive returns to child development.

Preschool might have other benefits – such as more affordable childcare or workforce participation for families. But we have found universal preschool, rolled out to everyone, does not necessarily pay off for development.

Investment should be made based on scientific evidence and take into account how programs will be affected as they are scaled up.

Without rigorous evidence from randomised controlled trials, money may be spent unwittingly on programs for Australian children that have no effect on development when the money could have been spent on alternative programs that yield positive results.

She Said is a formidable retelling of the journalism which sparked #MeToo – but also shows us how far we have to go

Source: The Conversation (Au and NZ) – By Andrea Jean Baker, Senior Lecturer in Journalism, Monash University

Universal Pictures

There is no spoiler alert in the Hollywood adaptation of the award-winning book She Said.

We know the story and the perpetrator, which is unusual. 80% of sexual violence cases go unreported. Perpetrators are rarely charged and continue to participate in society.

The perpetrator in She Said is the Hollywood producer Harvey Weinstein.
In 2020, Weinstein was found guilty of sexually assaulting two women in New York, and was sentenced to 23 years in prison.

She Said is based on the 2019 book of the same name by New York Times journalists Jodi Kantor and Megan Twohey.

Their Pulitzer prize winning investigative reporting in 2017, along with Ronan Farrow’s reporting for The New Yorker, uncovered Weinstein’s predatory behaviour and helped to ignite the #MeToo movement.

She Said follows in the footsteps of Spotlight (2015) and The Post (2017), films reflecting rigorous journalism: months of research, fact checking and persuading people to go on the record.

But newsrooms are overwhelmingly headed up by male senior staff. This impacts on whether stories about sexual abuse are covered and how they are covered.

She Said shines an important light on the need for rigorous journalism in holding the powerful to account.

A formidable cast and crew

She Said was created by a formidable female cast and crew. Director Maria Schrader, cinematographer Natasha Braier and writer Rebecca Lenkiewicz adapt the journalists’ fourth estate ethos with emotional intelligence.

Patricia Clarkson is savvy as the paper’s editor, Rebecca Corbett, who guides Kantor (Zoe Kazan) and Twohey (Carey Mulligan) through gruelling months of rejections, trying to bypass the nondisclosure agreements (NDAs) signed by Weinstein’s survivors.

The story is adapted with a keen emotional intelligence.

Mulligan is cool and sophisticated as Twohey forensically grills Weinstein’s lawyer about the NDAs, while suffering from post natal depression after having her first baby.

Kazan is diligently feisty as Kantor, a mother of two young girls who is shocked when she finds out her eldest discusses what rape is at school.

Disheartened by the manipulative misogyny in the Weinstein saga, Kantor is frustrated by the women who are reluctant to go on the record. One of these women, the actor Ashley Judd, eventually shared her story about Weinstein’s sexual misconduct and plays herself in the film.

Throughout the film, we watch as the code of silence continues: victim-survivors are reluctant to come forward about accusations for fear of the ramifications they will face.

In a 2019 documentary about Weinstein, Untouchable, he is reported saying to journalists who have been chasing the allegations for 15 years: “Don’t you know who I am!?”.

Despite the US legal system giving journalists broad leeway when publishing allegations that may be construed as defamatory, Weinstein’s behaviour went unchecked for decades.

#MeToo

She Said ends when the story about Weinstein by Kantor and Twohey is published in the New York Times in October 2017.

African American activist Tarana Burke began the MeToo movement in 2006 to address the sexual violence against Black women and girls. In 2017, in response to the Weinstein reporting, Alyssa Milano used this phrase to tweet about predatory sexual behaviour by men in Hollywood.

There would go on to be 85 million tweets about #MeToo.

This hashtag became a prominent example of digital feminism activism, where citizen activists created hashtags to highlight social issues the media was failing to report on. With “hashtag journalism”, reporters followed Twitter-led hashtag trends to assess what issues to cover in the news cycle.

Two women
With ‘hashtag journalism’, reporters looked towards Twitter to see what stories they should tell.

Despite the diversity of stories which came out of the #MeToo hashtag, initial reportage was primarily focused on white, middle-class women.

As Burke said:

I have no expectation of mainstream media to tell the stories of marginalised people unless it serves them.

The ‘Weinstein effect’

She Said vaguely reflects on the need for diversity in this reporting, but focuses on other difficulties of working in this space.

Kantor and Twohey come up against defamation issues, as well as the NDAs signed by the women. The film suggests certain laws need to be revised so journalists can continue to shine a light on injustices.

The “Weinstein effect” is the name which has been given to the increased reporting on systemic abuse following the journalism of Kantor, Twohey and Farrow.

Dozens of prominent men in the US have been held to account through the media.

Four people at an office desk
There has been an increase in reporting on sexual assault, dubbed the ‘Weinstein effect’.
Universal Pictures

In Australia, there is a lower level of protection from litigation, which has lead to an environment where there was been less reportage on those accused of sexual assault.

In both countries, those reporting on sexual violence are also increasingly aware that journalism must consider factors tied to race, sexuality and socioeconomic backgrounds.

There have been significant legal changes, too. Since #MeToo, 17 states in the US have restricted the use of NDAs, so more victim-survivors can speak out.

In Australia, we have seen the Respect at Work Bill, making employers legally responsible for eliminating workplace sexual harassment.

She Said is a compelling reminder of the catalyst for these changes.

100 years after insulin was first used, why isn’t NZ funding the latest life-changing diabetes technology?

Source: The Conversation (Au and NZ) – By Ben Wheeler, Associate Professor of Paediatric Endocrinology, University of Otago

This year marks a century since an extraordinary medical breakthrough – the use of insulin to treat diabetes mellitus. Some physicians at the time described the effect of administering this hormone as like witnessing “resurrection experiences”. Children near death were given a chance at life.

As we mark the centenary, we also need to focus on the pressing need in Aotearoa New Zealand to make the latest treatments and technologies available to all – and not just those who can afford them.

It is a remarkable story of medical and scientific progress.

The term “diabetes” was used from the first century BC to describe a condition characterised by polydipsia (thirst) and polyuria (passing large quantities of dilute urine); “mellitus” was added in the 1600s to indicate that sweetness in the urine differentiated this condition from other causes of these symptoms.

But it took another 300 years for a link between diabetes and the pancreas to be discovered. The term “insulin” was coined in 1909 by the Belgian scientist Jean de Meyer who speculated that a secretion from the pancreas could regulate the amount of glucose (sugar) in the blood.

Insulin was finally isolated from the pancreas in 1921 and was shown to keep dogs without a pancreas alive for several months. Rapid progress followed. In January 1922, 14-year-old Leonard Thompson, hospitalised and near death in Toronto, became the first person to receive insulin and survive diabetes.

Insulin arrives in New Zealand

By the end of 1922, insulin was being commercially produced and distributed worldwide. It is generally accepted that the first use of this miraculous substance in New Zealand was in 1923 when Dr (later Sir) Charles Burns injected Isobel Styche with insulin in Dunedin Hospital.

There’s some debate about this, however, with another patient possibly receiving treatment as early as 1922.

A young New Zealand doctor named Thomas Johnson, at that time working in London, heard about the discovery of insulin and realised it might save the life of Jake Cato, a young man he had been looking after in Napier.

In collaboration with Cato’s father, who happened to be the head of the New Zealand Shipping Company based in Napier, Johnson arranged for one of the company’s ships to bring the precious substance to New Zealand.

Breakthroughs in glucose monitoring

At the same time as insulin therapy was being developed, glucose-monitoring technology was also progressing. Crude assessment of glucose in the urine, used in New Zealand until the early 1980s, was superseded by the development of finger-prick blood-glucose measurements.

Performed up to ten or more times daily on hand-held meters, finger-prick measurements remain the reality for most of the 25,000 children and adults who live with type 1 diabetes in New Zealand.

This particular form of diabetes results in an absolute deficiency of insulin. It’s caused by the body’s immune system attacking and destroying the insulin-producing cells in the pancreas.

The discovery of insulin: a story of monstrous egos and toxic rivalries


Over the past ten years, the pain and burden of finger-prick glucose monitoring have encouraged the development of continuous glucose monitors (CGMs). These small patches, worn on the skin, measure glucose levels continuously and are replaced every seven to 14 days.

CGM devices can now “talk” to insulin pumps, devices worn on the body that provide continuous subcutaneous insulin instead of the many injections required daily. These technologies act like a partially automated artificial pancreas, reducing the large number of complex decisions people with diabetes have to make daily to remain healthy.

Insulin pumps deliver continuous, measured doses, meaning multiple daily jabs aren’t required.

Treatment and equity

While insulin pumps are funded in New Zealand, the government drug-buying agency Pharmac does not fund CGMs. That’s despite CGMs being funded in the UK, Canada, Australia (since 2017) and much of Europe, and being the recommended method of glucose monitoring in all major diabetes guidelines worldwide.

However, CGMs are widely used in New Zealand by those who can afford them. They help prevent the unpleasant effects of low blood glucose and can give advance warning of less common but serious risks of collapse and seizures, and occasionally death.

New Zealand needs urgent action to tackle the frightening rise and cost of type 2 diabetes


CGMs also help mitigate long-term complications and early death from too much glucose.

The lack of government funding has led to widespread inequity. Māori, Pacific peoples and those on lower incomes are less able to access life-enhancing CGM devices. Recent New Zealand research has highlighted that glucose outcomes for Māori, if they are wearing a CGM, appear equal to those for non-Māori.

Better health for all

Jake Cato’s life-saving insulin therapy was made possible by the wealth and connections of his parents. We would like to think that in 2022, a century on from the first person in the world receiving insulin, this should not still be a factor.

Access to life-saving and disability-preventing therapies for the one-in-500 New Zealand children (and thousands of adults) living with type 1 diabetes must not be restricted to those with money and connections.

That’s why the wider availability of diabetes management technologies – taken for granted in other comparable countries – is the big issue this Diabetes Action Month, and will be highlighted at the forthcoming Transforming lives: 100 years of insulin event in Wellington.

While there is much to celebrate during this centenary year, the good health promised by these medical breakthroughs is still not available to all in Aotearoa New Zealand. We can and should do better.

Albanese-Xi meeting won’t resolve Australia’s grievances overnight. But it is a real step forward

Source: The Conversation (Au and NZ) – By James Laurenceson, Director and Professor, Australia-China Relations Institute (ACRI), University of Technology Sydney

There were smiles all round as the Australian and Chinese leaders met formally for the first time in more than six years.

The meeting was brief, just 32 minutes, but Prime Minister Anthony Albanese led afterwards with the message that it “was a positive and constructive discussion”.

President Xi Jinping said in his opening remarks that the difficulties in the bilateral relationship were not what the Chinese side wanted to see.

Yet beyond conciliatory words and photo opportunities, the Australian public is being hit with contrasting takes on what the meeting means for relations with our most important trading partner and the “big guy” in the regional room.

On one hand, it’s been described as a “landmark” and “historic” event – a “huge reset” of Australia-China ties.

What’s conjured up is images of wine and rock lobster flowing freely through Chinese customs once again, and the detained Australians Yang Hengjun and Cheng Lei stepping off the prime ministerial jet alongside Albanese when it lands in Sydney later this week.

Others, however, are keen to moderate expectations. Treasurer Jim Chalmers warned earlier this week that

I don’t think anybody pretends that some of the issues that China has raised, certainly some of the issues that we have raised, will be solved overnight.

A diplomatic off-ramp

The reality is that Canberra and Beijing’s assessments of their respective interests remain far from aligned.

For starters, let’s be clear on what led to a meeting even taking place. Two factors combined, with neither being sufficient alone.

First, by the end of 2021, Beijing had ample evidence the hardline approach it was taking to shifting Canberra’s positions wasn’t working.

The trade sanctions deployed in 2020 were having no discernible impact on the Australian economy at large. They were, however, generating plenty of negative headlines for China internationally.

Meanwhile, Australian public opinion towards China collapsed. By early 2022, polling revealed that far from backing down, 58% of Australians supported the adoption of a “harder Australian government line on China”, compared with just 17% who disagreed.

This meant Beijing was alive to face-saving off-ramps.

Second, by restoring diplomacy to centre stage in managing China relations, the new Australian government delivered such an off-ramp. Australian political leaders were now once again referring to China as a “comprehensive strategic partner”, while emphasising that “both sides”, not just China, would need to reflect on their handling of differences. Challenges posed by China’s behaviour are acknowledged by the current government but not talked up for domestic political gain.

It’s no coincidence that needlessly provocative rhetoric provided the trigger for Beijing cutting off senior-level political dialogue in early 2020. A tighter diplomatic ship overseen by Foreign Minister Penny Wong has now permitted its restoration.

With a new Australian government and foreign minister comes fresh hope for Australia-China relations


A step forward

The next question is, will the meeting make a practical difference?

Albanese himself said that simply “having the meeting is a successful outcome”.

That’s not as trite as it might sound.

A meeting does not guarantee the Australian grievances will be addressed. But there’s no doubting that in China in 2022, the person these grievances need to be put to, and who has the authority to address them, is the Chinese president.

Even superpowers understand this. In the lead-up to a meeting between US and Chinese leaders on Monday, President Joe Biden’s national security advisor Jake Sullivan emphasised that

There just is no substitute for this kind of leader-to-leader communication in navigating and managing such a consequential relationship.

We can also be confident that a decisive signal has now been sent throughout the Chinese bureaucracy that there’s official blessing to engage with Australia again.

A meeting of trade ministers to dig into ongoing disputes would naturally follow.

Australia’s ambassador in Beijing, Graham Fletcher, can expect to see his access improved.

Even Chinese companies considering investing in Australia, and parents weighing up whether to send their children to study here, will now be revising their assessments of risk downwards, the opposite of the trend in recent years.

Another factor giving cause for optimism is that while the Australian government hasn’t offered up compromises to get trade sanctions removed or detainees released, Albanese will have been able to credibly deliver messages directly to Xi that assuage core Chinese sensitivities.

Behind closed doors, he would have been able to say that Australia’s position on Taiwan and our “One China” policy has not changed since diplomatic relations were struck 50 years ago. The Australian government unequivocally does not support Taiwanese independence.

And in contrast to the US, nor do we support the economic containment of China. On Monday, Trade Minister Don Farrell went as far as describing recent trade sanctions on China imposed by the Biden administration as “draconian”.

The meeting isn’t a “reset” back to the sunny days of 2015. But it is on the dysfunction since 2020. Australia is a step closer to having a relationship with China on par with what other US allies and partners in the region have been able to maintain all along. And that’s unambiguously a positive step forward.

Last month Federal Treasurer Jim Chalmers unveiled the National Housing Accord, intended to build a million new homes in Australia. Part of the plan is to encourage superannuation funds to invest in social and affordable housing.

The proposal was met with criticism from some quarters, with critics arguing Australia’s superannuation savings belongs to its members:

it is their money, not Labor’s play money.

These critics are forgetting it was not so long ago people’s taxes (which can also be seen as “their” money) paid everyone’s pensions. And while in consolidated revenue on their way to keeping us in comfort in our old age, these taxes helped build extensive public and social infrastructure.

The transfer of retirement funding from the national government to non-government super funds is just one example of the shift from public provision of social goods towards individual accumulation that has defined Australian politics for four decades. This shift, along with associated income tax cuts, has contributed directly to the housing affordability crisis via the emphasis on property as an investment.

Australia’s super funds now control $3.3 trillion – the fourth-largest pool of retirement savings in the world.

Most of them invest in fossil fuels and some, directly or indirectly, in armaments, exploited labour and old-growth logging. All of them invest internationally where, if they are not doing actual harm, they are still not doing any good for their members in Australia beyond delivering financial returns.

Super funds are regulated by federal legislation which originally stipulated they must act in the “best interests of their members”. This was changed by the Coalition government in 2020 to read “best financial interests”. It is this requirement that has the critics of Chalmers’ plan baulking: how can it be in members’ best financial interests to invest in social housing?

Why super funds should invest in social housing

If even 1% of the $3 trillion – $30 billion – were invested in social housing, rental pressures in the private housing market would be massively reduced as tens of thousands of households currently in the private rental market vacated those dwellings for new social housing.

The flow-on effects of decent secure housing, including improvements in physical and mental health, and general social welfare are well documented.

The Albanese government could re-amend the regulations to their earlier form, and could require all super funds to invest a proportion of their portfolios in socially and ethically beneficial activities.

Super fund members are workers and members of society too, making up most of the adult population. They would all benefit from a more equal society.

Investing for social good is already happening

Some local funds and other financial institutions are already investing in social goods. Various super funds like CBus and community banks like Bank Australia invest in or give low-interest loans to community housing associations. Australian Super has a 25% stake in Assemble, an affordable housing developer – bought before the 2020 amendment.

Community banks and European funds are already investing in low yield, low risk social investments.

They are taking small steps in a direction that is well-established in many European countries, where the notion of corporate responsibility has much greater resonance. This can be seen in the German constitution, which stipulates property ownership entails obligations, and “its use shall also serve the public good.”

European funds are finding low-yielding, slow-returning investments in social and co-operative housing complement their diverse portfolios well. Germany’s UmweltBank supports various housing initiatives including the famous Spreefeld co-op in Berlin, which provides a steady, low-risk return.

Investments in social housing are regarded as the lowest risk of all, as rents are mostly paid from financial assistance guaranteed by the state. Pension funds and community banks can commit to the long term, unlike corporate investors that purchase social housing for a limited period before selling it on the private market.

Oversight of these initiatives must be careful and regulated, but there is no reason why they should not be implemented. Chalmers’ plan should be applauded, and could go much further.

You are now one of 8 billion humans alive today. Let’s talk overpopulation – and why low income countries aren’t the issue

Source: The Conversation (Au and NZ) – By Matthew Selinske, Postdoctoral research associate conservation science, RMIT University

Today is the Day of Eight Billion, according to the United Nations.

That’s an incredible number of humans, considering our population was around 2.5 billion in 1950. Watching our numbers tick over milestones can provoke anxiety. Do we have enough food? What does this mean for nature? Are more humans a catastrophe for climate change?

The answers are counterintuitive. Because rich countries use vastly more resources and energy, greening and reducing consumption in these countries is more effective and equitable than calling for population control in low income nations. Fertility rates in most of the world have fallen sharply. As countries get richer, they tend to have fewer children.

We can choose to adequately and equitably feed a population of 10 billion by 2050 – even as we reduce or eliminate global greenhouse gas emissions and staunch biodiversity loss.

For most high income countries, population growth has fallen below the replacement rate of 2.1 children.
Unsplash.com

Why is the world’s population still growing?

We hit 7 billion people just 11 years ago, in October 2011, and 6 billion in October 1999. And we’re still growing – the UN predicts 9.7 billion humans by 2050 before potentially topping out at 10.3 billion at the end of the century. But modelling by the Institute for Health Metrics and Evaluation predicts the population peak much earlier, in 2064, and falling below 9 billion by century’s end.

Why is it still growing? Momentum. The number of women entering child-bearing age is growing, even as the average number of children each woman is having falls. Plus, we are generally living longer.

In 1950, the world’s population was growing at almost 2% a year. That growth rate is now less than 1%, and predicted to keep falling. There’s little we can do to change population trends. Researchers have found even if we introduced harsh one-child policies worldwide, our population trajectories would not change markedly.

In many ways, the story of population growth is evidence of improvement. Better farming techniques and better medicine made the population boom possible. And slowing population growth has come from falling rates of poverty, as well as better health and education systems, especially for women.

Increased gender equality and women’s empowerment have also helped. Put simply, if women can choose their own paths, they still have children – just fewer of them. That’s why climate solutions group Project Drawdown ranks female education and family planning as one of the top ways to tackle climate change.

Should we worry about overpopulation at all?

You are now one of 8,000,000,000 humans alive today. How should we feel about this?

The modern fear of overpopulation has old roots. In 1798, Reverend Thomas Malthus warned population grows exponentially while food supply does not. Close to two centuries later, Paul and Anne Erlich’s 1968 book The Population Bomb triggered a new wave of concern. As our numbers skyrocketed, they argued, we would inevitably hit a Malthusian cliff and run out of food. Famine and war would follow. It didn’t happen.

What resulted was inhumane population control policies. The book – replete with racially charged passages about a crowded Delhi “slum” –  directly influenced India’s 1970s forced sterilisation policies. China’s notorious one-child policy emerged from similar concerns.

‘Overpopulation’ and the environment: three ideas on how to discuss it in a sensitive way


Low- or middle-income countries are most often called on to tackle overpopulation. And the people calling for action tend to be from high-income, high-consumption countries. Even David Attenborough is concerned.

Recent calls by Western conservation researchers to tackle environmental degradation by slowing population growth repeat the same issue, focusing on the parts of the world where populations are still growing strongly – sub-Saharan Africa, Latin America and some Asian countries.

People from lower income countries reject these calls. In 1996, Pakistani academic Adil Najam wrote these countries were “weary of international population policy in the name of the environment.”

Overall, the world’s wealthiest 1% account for 15% of the world’s carbon emissions. That’s more than double the emissions of the poorest 50% of the planet – who are the most vulnerable to climate change.

Prince William, for instance, has linked African population growth to wildlife loss – even though he has three children and comes from a family with a carbon footprint almost 1,600 times higher than the average Nigerian family.

What about saving wildlife? Again, a mirror may be useful here. It turns out demand from rich countries is the single largest driver of biodiversity loss globally. How? Your beef burger may have been made possible by burning the Amazon for pasture for cows, as well as many other global supply chain issues. Rich countries like Australia are also notoriously bad at protecting their own wildlife from agriculture and land clearing.

Destroying rainforest is bad – but what if it’s being destroyed to make beef or palm oil for richer countries, as in this photo of clearing for oil palms in South-East Asia.

This is not to say population growth in lower income countries isn’t worth discussing. While many countries have seen their populations taper off naturally as they get wealthier, countries like Nigeria are showing signs of strain from very fast population growth. Many young Nigerians move to cities seeking opportunities, but infrastructure and job creation has not kept pace.

For Western environmentalists and policymakers, however, it would be better to shift away from a blame mentality and tackle drivers of inequality between and within nations. These include support for family planning, removing barriers to girls’ education, better regulation of global financial markets, reduced transaction costs for global remittances, and safe migration for people seeking work or refuge in higher income countries.

This graph shows what fair use of the world’s resources would look like (green line) and what proportion is actually used by high and low income countries.

As we pass the eight billion mark, let’s reconsider our reaction. Blaming low-consumption, high-population growth countries for environmental issues ignores our role. Worse, it takes our attention away from the real work ahead of transforming society and reducing our collective impact on the planet.

Cannon-Brookes shakes up AGL: what now for Australia’s biggest carbon emitter

Source: The Conversation (Au and NZ) – By Mark Humphery-Jenner, Associate Professor of Finance, UNSW Sydney

“What is a grok?” asked a shareholder at AGL’s 2022 annual general meeting at the Melbourne Recital Centre on November 15, as those assembled struggled with the reality being forced on Australia’s biggest carbon emitter by Australia’s third-richest person.

Grok is, in fact, a word invented by science-fiction writer Robert Heinlein for his 1961 novel Stranger in a Strange Land. To “grok” means to understand something intuitively.

Which is not something likely to be said about how AGL’s leadership has appreciated the ambition of software billionaire Mike Cannon-Brookes to have Australia’s biggest energy retailer lead the nation’s transition to renewable energy.

At the meeting, Cannon-Brookes used the 11.3% shareholding he has collected through his investment company Grok Ventures – plus proxies and support from other shareholders sympathetic to his cause – to reshape the company’s board.

Before the meeting AGL had five directors, including chairperson Patricia McKenzie. It now has four new independent directors – all nominated by Cannon-Brookes.

McKenzie and her other directors endorsed just one of those nominees – Mark Twidell, a renewable energy expert who works for Tesla Energy. The other three new directors are: Kerry Schott, past chair of the federal Energy Security Board; John Pollaers, Swinburne University’ chancellor; and CSR director Christine Holman.

The existing board also suffered the indignity of a significant minority vote against its executive compensation plan, as well as against AGL’s energy transition plan, which commits to quitting fossil fuels by 2035. For some, the plan was not ambitious enough. For others, the business case was unclear.

Shareholders divided

Yet as Cannon-Brookes’ forces swept the field, the same shareholder wondering about the meaning of “grok” also wondered whether the new directors would work for Cannon-Brookes or for AGL. So too did others. Division was palpable.

Shareholders now seem almost caught in a civil war.

On one side are those focused on sustainability, and carbon emissions, who support Cannon-Brookes in his mission to see AGL to divest fossil fuels quicker. Though his takeover bid failed, in May he successfully blocked AGL’s demerger plan, which he argued would delay divestment.

Australia’s biggest carbon emitter buckles before Mike Cannon-Brookes – so what now for AGL’s other shareholders?


On those other side are those focused on returns, and concerned about “board capture”.

These interests need not be mutually exclusive. A company can operate sustainably and be profitable at the same time. But its leadership must explain this and make the strategy clear, cohesive and credible.

Board missed its opportunity

McKenzie talked strongly about the need to move towards renewable energy. She said AGL’s transition plan must be “sensible”. But there was a lack of focus on financials.

Directors owe a duty to all shareholders to act in the best interests of the corporation. This requires directors to focus on opportunities to maximise shareholder wealth, but doesn’t negate doing so sustainably.

New director John Pollaers came closest to articulating the challenge facing AGL. This was a time for strategic change, he said. AGL had an opportunity to generate returns and find a path to profitable growth.

McKenzie and her fellow directors could have used the opportunity to show how the renewable energy transition is necessary for AGL’s ongoing financial success, or provide new avenues for wealth creation.

But they awkwardly tried to find a middle ground, promoting the clean energy transition without fully outlining the financial underpinnings until pressed: McKenzie ultimately noted the transition must be “reasonable” to be financially viable.

Finding a shared vision

In lieu of this vision, questions revolved around the board’s competence and record.

Shareholders went into the meeting with AGL’s stock worth A$7.70. That’s better than the $5.30 it was worth a year ago, but about 70% less than the $25.81 it traded at five years ago.

The vote against the board’s executive compensation plan sets the scene for further boardroom upheaval.

Under Australia’s “two-strike” rule on executive pay, at least 75% of shareholders must approve a board’s compensation plan. More than 25% opposition results in a strike. A second strike leads to a “spill resolution” – a vote on whether all directors must stand for re-election.

Whether that occurs will depend on how successfully old and new directors can work together – something incoming director Christine Holman noted in her pitch to shareholders.

The end of coal-fired power is in sight, even with private interests holding out


First they must find a new chief executive, to replace Brett Redman who resigned in April. A new CEO can give clarity over AGL’s future priorities – but to do so he or she will need to be palatable to both sides.

If they can’t find agreement, then AGL’s next meeting of shareholders promises to be even more spectacular.

Raves, repairs, and renewal: how young Ukrainians are bringing joy to the rebuilding effort

Source: The Conversation (Au and NZ) – By Clare M. Cooper, Design Lecturer, University of Sydney

After more than 250 days of assaults from Russian forces, Ukrainian resistance is taking more surprising forms. In an attempt to reconnect to their pre-invasion cutting-edge techno scene a group of young activists have been organising “repair raves” to attract people to help with the massive clean-up effort, dancing together while they do it.

Back in August, it was estimated that over 100,000 Ukrainian houses have been destroyed, but also over 700 key cultural facilities and 20 youth centres are now in ruins. The teens and 20-somethings who would be clubbing in these spaces, are now flocking to volunteer to clear rubble, and repair infrastructure at strategically targeted raves, all while dancing to their favourite DJs.

The group of young activists and music-lovers behind Repair Together are joining a long line of grassroots design activists drawing on joy, humour and friendship – what we refer to as pleasure tactics – to attract and sustain a people-powered movement that is helping to repair a war-torn country.

What is the ‘repair rave’ movement in Ukraine?

For those new to this term – a rave is a dance party (often free, sometimes not entirely legal) where DJs play electronic music (mostly techno) to people who are committed to dancing together – and dancing hard.

After the recovery began in many of the war-ravaged towns, a group of young passionate ravers started hosting targeted repair raves to meet the need for community labour. As winter approaches, the need for clearing rubble and building housing is becoming increasingly urgent. The most recent Instagram post from Repair Together invites followers to join the raves now focused on Kyiv.

In an recent interview with Dazed one of the organisers, Marina Grebinna, shared that the raves grew from 50 volunteers at their first event in Yahidne in July 2022, to hundreds travelling from as far afield as the USA more recently.

Grebinna explains they were cautious about planning parties in places where people had died:

But it was a good way to involve a lot of people, and we really wanted to make volunteering seem like a lifestyle choice… Now, after three months of work on this project, we see a lot of familiar faces. A lot of people do it on a regular basis now.

Responsive, creative, community-driven events like these have two powerful effects. The first is for those directly affected by the violence of war – reconnecting to one another and to a culture and music that they love, resisting the physical and spiritual oppression of war.

The second is for those who have become desensitised to the tragic news of the ongoing conflict, who are drawn in once again due to the seeming incongruity of the pleasure alongside the violence and loss. The idea that people could be enjoying themselves – even raving – during wartime efforts to restore some sense of “home” doesn’t fit with what we consider a picture of conflict, grief, and suffering.

Dancing the talk

The Repair Together events are a perfect example of the kind of grassroots design activism that is not instantly recognised as activism.

Volunteers connect to one another through music, but also spend time listening to stories of the survivors in these towns as they work, bolstering their resolve to create their “new Ukraine”. The visual communication (collages on social media, videos of events) are all invitations to combat the paralysis of oppressive violence and be a proactive part of this future.

It is a beautiful example of the proactive design futuring I research and teach – where people share detailed parts of the futures or society they desire, and then get their hands dirty building it together – not waiting around for it to be done for them/us.

These repair raves sit within a rich history of activism that takes on surprising forms, intersecting with cultural events in new ways, and involving people beyond fundraising, rallies, or petitions by focusing on what design researcher Lenskjold refer to as denoting “collaboration rather than persuasion” in this 2015 journal article.

Parties with purpose, and transitional neighbourhoods

Here in Australia we’re familiar with parties with purpose. Queer and First Nations communities have led the way with Sydney Mardi Gras, and free party crews like Ohms Not Bombs (“dig the sounds not uranium”) have been attracting people to party while protesting for over 30 years.

The city as laboratory: what post-quake Christchurch is teaching us about urban recovery and transformation


The direct community clean-up, design, and rebuilding of the Repair Together movement mirrors the creative collaboration of post-quake Christchurch residents. After 80% of the central city was destroyed, and over 10,000 houses demolished, the “urban recovery and transformation” took surprising forms such as washing-machine powered dance-o-mats, and port-a-loo beautification.

Several years after the quake, chair of the Christchurch Transitional Architecture Trust (Dr Barnaby Bennet said,

Hundreds of temporary and transitional projects continue to pop up in the city. International interest in forms of adaptive urbanism and temporary architecture have led to media outlets such as The New York Times and Lonely Planet hailing the vibrant and innovative nature of this projects as a symbol of recovery.

Earnest activism is over, bring on the pleasure

Fatigue and paralysis are common responses to overlapping crises and horrific information.

This is especially true for long-term and overlapping struggles. If your actions and activism don’t bear fruit then it is hard to keep it up. A common approach is to burn hard, and burn out, with the next batch of volunteers following suit. This has been endemic in environmentalist fights, and certainly exists in all battles against systemic problems like racism and sexism, which at times – even with small wins – seem insurmountable.

But activism can take surprising and joyful forms, intersecting with cultural events and ways of being together that actually energise, connect and inform people.

We need to learn from these creative approaches – especially as anti-protest laws (particularly relating to climate activism) continue to escalate.

To start cutting gas and electricity prices, here’s what the government looks likely to deliver by Christmas

Source: The Conversation (Au and NZ) – By Peter Martin, Visiting Fellow, Crawford School of Public Policy, Australian National University

Treasurer Jim Chalmers says he’ll have a system in place to deal with rising energy prices by
Christmas.

He can’t yet tell us what it will be, because that will depend on the outcome of negotiations with gas and electricity companies, and possibly on legislation he might have to get through parliament.

But thanks one of the treasurer’s most trusted confidants, we can now piece together a pretty good picture of what lies ahead.

Clues from the head of Treasury

The head of the treasurer’s department, Treasury secretary Steven Kennedy, shared his thoughts with a Senate estimates committee last week.

Treasury Secretary Steven Kennedy.

While Kennedy presented them as his own thoughts, Kennedy’s day job is helping Chalmers work out what to do.

The first thing to note is that Kennedy, like Chalmers, doesn’t like the idea of intervening in markets just because prices are high.

As he told the Senate, usually the solution to high prices “is high prices”.

What he means is that usually when prices jump it’s because there isn’t enough of something. The high prices encourage new suppliers to get into business supplying that thing, and that forces prices down.

If that can’t happen quickly enough, the high prices will encourage users of that something to switch to a substitute, as we did when cyclones hit Queensland’s banana crops in 2006 and 2011. We switched to other fruits grown elsewhere.

Interfering with high prices interferes with those adjustments. Usually.

Cheaper gas and electricity are within our grasp – here’s what to do


However, at the moment, there needn’t be an Australian gas shortage. Australia’s east coast produces roughly three times as much gas as it uses each year.

Although most of the rest of the gas is exported in accordance with long-term contracts, an increasing amount is being exported over and above those contracts to take advantage of the temporary spike in international prices following Russia’s invasion of Ukraine.

If that gas was sold here at pre-invasion prices, there wouldn’t be a shortage, and Australian prices wouldn’t be up to four times what they used to be, pushing manufacturers to the brink and pushing electricity prices way beyond normal.

Whatever is done will be temporary

Kennedy’s first point is that the global price hike is likely to be temporary, or as he put it, “hopefully temporary”. Even if the conflict persists, international supply and demand are likely to adjust to bring global prices back down. That means any intervention should be temporary, so it doesn’t distort markets forever.

Kennedy’s second point is that the gas exporters selling for ultra-high prices over and above what they are contracted to sell are making exceptionally high profits – “well beyond the usual bounds of investment and profit cycles”. They would do just fine if their profits were merely ordinarily high rather than super high.

His third point is that the temporarily high prices are hacking into the profits of other Australian businesses and “raising questions about their viability”.

Leading economists back federal government action to curb rising gas and electricity prices


Households, especially lower-income households, will be severely affected.

Summing up more clinically, Kennedy says what’s happening in Ukraine is “leading to a redistribution of income and wealth, and disrupting markets”.

The national interest case for this redistribution is “weak, and it is not likely to lead to a more efficient allocation of resources”.

Beyond a gentleman’s agreement

In August the government signed a sort of gentleman’s agreement with the three east coast gas exporters in which they’ve agreed to offer uncontracted gas to local customers first, before offering it overseas.

But (and it’s a big but) they’ll offer it at international prices, with the only stipulation being that local customers “not pay more” than overseas customers.

Although well-intentioned, it will allow prices many times higher than the A$8 a gigajoule that was common before COVID – high enough to send some customers to the wall.

The two-step solution Kennedy is pointing to goes further, temporarily.

Agreement on lower prices – or a tax might be next

The first step is likely to be to ask the producers to supply enough gas to local customers to get local prices down to A$10 a gigajoule, an idea suggested by the former Australian Competition and Consumer Commission chief Rod Sims.

Sims thinks the producers are likely to agree. The Commonwealth has the power to impose export controls. If they don’t agree, Kennedy has hinted at stage two.

Politics with Michelle Grattan: Rod Sims on the gas price crisis


That fallback position would be a temporary tax on the excess profits of exporters and use it to subsidise domestic prices, along the lines of the temporary tax in the United Kingdom.

Economic purists, including those surveyed by The Conversation this month, would prefer the tax was paid to the victims of ultra-high prices in cash, rather than in subsidised prices, because it would encourage them to get off gas.

But Kennedy (and probably Chalmers) believe the ultra-high prices are temporary. Both want to bring down the current ultra-high rate of recorded inflation. It’s something price subsidies would do, but cash handouts would not.

Grattan on Friday: We must find a way to get gas prices down, but how?


The two-step nature of the process is probably why it is taking so long.

Chalmers and colleagues need both to ascertain what the exporters are prepared to do about prices if merely asked, and to prepare legislation for a temporary tax should they need to take that final step.

How metal-munching microbes help the rare, toxic element tellurium circulate in the environment

Source: The Conversation (Au and NZ) – By Owen Peter Missen, Research Assistant in Geochemistry, Monash University

Tellurium pieces Jan Askeit / Wikimedia, CC BY-SA

New technologies often mean elements start moving through the environment in new ways. Take lead plumbing: it helped provide access to fresh water for the masses, but left a toxic legacy that remains to this day.

As we transition away from fossil fuels, we are turning to technologies reliant on rare elements that had few uses in the past. One of these is tellurium, an element found in an increasing number of solar panels.

How do we anticipate the potential pitfalls of a dramatic increase in the flux of tellurium through the biosphere? And how do we secure safe and reliable supplies of this commodity?

To start answering these questions, we travelled to an abandoned gold mine in Mexico – and discovered how metal-munching microbes are moving this elusive element through the environment.

Elements on the move

Tellurium is as rare as gold in Earth’s crust, with only around 1 milligram in each metric tonne of average crustal rock. The silvery substance was discovered only in 1783, and until recently its main claim to fame was the fact it can make you smell unpleasantly like garlic if you handle it.

Tellurium is often found in gold deposits. Despite gold’s famous reputation for durability, over the past 15 years we have discovered the precious metal is remarkably mobile in the environment – even growing in trees!

Gum trees reveal possible gold ore deposits


It turns out certain microbes can effectively munch on gold, slowly transforming gold nuggets into chemical forms that can move through the environment. These mobile gold compounds (particularly ones that can dissolve in water) are quite toxic: only a few metal-resistant microbes can thrive in the unique micro-environment found on the surface of a grain of gold.

Microbes and organic material on the surface of native gold (left) and tellurium (right) contribute to active cycling of these rare elements. Newly formed tellurium nanoparticles are highlighted in the yellow circles.
Missen et al.

Can tellurium move like gold?

We wanted to test whether microbes can cycle tellurium through the environment in the same way they do for gold. We used natural ore deposits to do this, but this gives us information about what would happen if tellurium-rich materials were dumped by humans.

Finding a suitable site was a challenge. Since high tellurium content is associated with high gold content, most tellurium deposits close to the surface (such as those near Kalgoorlie, Western Australia) have been mined out a long time ago.

Eventually our quest led us to Moctezuma in Mexico, where there is a small former gold mine that is exceptionally rich in tellurium.

Metallic tellurium in the fresh ore (left) oxidises to colourful minerals near the surface (green emmonsite in the middle panel). Further away from the vein, tellurium can still be detected (right), but does not form its own minerals.
Missen et al.

At the mine, we studied ores and soils away from the main vein of gold and tellurium. We found tellurium was moving away from the richest ore, and discovered the first evidence of natural tellurium nanoparticles on the surface of pieces of native tellurium.

This discovery is significant because nanoparticles play a special role in the environment, as they have different properties compared to macro-particles. For example, they tend to be more reactive than larger particles, and they may be toxic in their own right.

The tellurium nanoparticles we found appeared very similar to gold nanoparticles that have previously been found on the surface of gold grains.

In in-vitro experiments, some microbes present in gold- or tellurium-rich environments are able to excrete nanoparticles of the metals dissolved in the growth medium, thereby detoxifying their environment. On the left, a Serratia cell shows many gold particles on the cell surface (lighter blobs); on the right, a cross-section through a Rhodococcus cell shows needle-like particles of tellurium growing in (arrow) and around the cell.
Missen et al. / Presentato et al.

Nanoparticles and microbes

We also showed that gold and tellurium have rather different modes of transport in soils and groundwater.

Gold particles can be carried a long way in rivers, for example. However, tellurium metal oxidises quickly when exposed to air, forming highly soluble – and toxic – compounds. Hence, there is no physical transport of grains of tellurium in metallic form.

The movement of tellurium is also limited by reaction with common minerals in soils. This is a good thing, since tellurium’s limited mobility keeps concentrations in groundwater low, and hence limits toxic effects.

In our latest research, we have detected tellurium nanoparticles in the soil of Moctezuma, away from the metal-rich outcrops.

Because metallic tellurium nanoparticles are highly reactive and not expected to survive for long in soils, this discovery provides the strongest evidence yet that microbes are actively helping to cycle this rare element through the environment. Tellurium in these soils in most likely subject to a dynamic cycle of oxidation and dissolution followed by reduction and precipitation, all controlled by microbial activity.

Cleaner mining

We are only now beginning to understand how microbes cycle “exotic” elements such as tellurium. Understanding these “biogeochemical” processes is important to understand how elements move in our landscapes. We can then assess potential risks, and design efficient mitigation strategies.

This understanding can also aid in developing more sustainable mining (and recycling) technologies. Around Moctezuma, at least, microbes effectively separate gold from tellurium in soils.

Innovative solutions will be required to address our planet’s need to generate more energy more sustainably, and cleaning up mine product processing to better separate all potential commodity elements is just one of these ways.

Calls for a ‘one-child policy’ in India are misguided at best, and dangerous at worst

Source: The Conversation (Au and NZ) – By Aprajita Sarcar, Laureate Postdoctoral Fellow, UNSW Sydney

India will surpass China as the country with the world’s largest population in 2023, according to the United Nations World Population Prospects 2022 report.

The UN also projects the global population has reached eight billion as of Tuesday.

As early as March 2022, reports circulated on Chinese social media that India’s population had already surpassed China’s, though this was later dispelled by experts.

Women in India today are having fewer children than their mothers had. But despite a lower fertility rate, the country’s population is still growing.

The idea the country should adopt something like China’s former “one-child policy” has been moving from the fringe to the political mainstream.

But the notion that India should emulate China’s past population policies is misguided at best, and dangerous at worst.

Both countries are struggling with the legacy of harsh population policies, and stricter population controls in India could have disastrous consequences for women and minority communities.

Given Australia’s growing ties to India, it should be concerned about what population policy could mean for the erosion of democratic norms in India.

Unintended consequences

India implemented the world’s first national family planning program in 1952. The birthrate began to drop, but only gradually, and family sizes remained stubbornly high. The government then implemented widespread forced sterilisation particularly of Muslims and the urban poor, especially during “The Emergency” years of 1975-77.

After the founding of the People’s Republic of China in 1949, infant mortality dropped significantly. Between 1950 and 1980, China’s population almost doubled. The “one-child policy” – limiting births per couple through coercive measures – was implemented in the early 1980s, and fertility dropped dramatically.

In both India and China, these population policies had unintended consequences.

In China, the government found that once fertility rates dropped, they were faced with an ageing population. Even after relaxing birth control policies to allow all couples to have two children in 2015, and three children in 2021, birth rates remain low, particularly among the urban middle class favoured by the government.

In both countries, skewed sex ratios caused by sex selective abortions have led to a range of social problems, including forced marriages and human trafficking.

China has found that despite reversing course, it cannot undo this rapid demographic transition. Urban, middle-class couples face mounting financial pressure, including the cost of raising children and of caring for the elderly. While the government has encouraged “high quality” urban women to give birth, rural and minority women are still discouraged from having more children.

As in China, in some states in India, women’s education and their aspirations for their children have contributed to lower birth rates. Like China, these states now face an ageing population. Birth rates in other states with high Muslim populations have also declined, but at a slower rate.

Unfair impact

Despite declining birth rates, some politicians have advocated for the adoption of something like China’s former one-child policy in northern states with large Muslim populations. These calls have less to do with demographic reality, and more to do with majoritarian Hindu nationalist concerns around Muslim and “lower-caste” fertility.

The worry here is that the coming population milestone will push India to adopt knee-jerk population policies. These could in turn unfairly affect women and minorities.

Four Indian states with large Muslim populations have already passed versions of a “two-child policy”. What’s more, built into many of these policies are incentives for families to have just one child. And in 2021, a senior government minister proposed a national “one-child” policy.

Like past population control policies, they’re targeted at Muslim and lower-caste families, and illustrate a broader Hindu nationalist agenda with anti-democratic tendencies.

As happened at the height of China’s one-child policy, Indians could lose government jobs and more if such laws were passed at the national level. Some Indian states and municipalities have already legislated that people with more than two children are ineligible for government jobs and to stand for political office.

The irony is that India’s birth rate and the size of families are decreasing because of women’s own reproductive choices. Many women are getting surgical contraception after having two children (or after having a son).

However, financial inducements for doctors and the women means poorer women are pressured to undergo these procedures.

In other words, the trend in India is towards smaller families already. As the 2022 UN report itself notes, no drastic intervention from the state is required.

‘Gain of function’ research can create experimental viruses. In light of COVID, it should be more strictly regulated – or banned

Source: The Conversation (Au and NZ) – By Colin D. Butler, Honorary Professor, Australian National University

The United Nations Environment Programme recently published a scientific review that looks at environmental threats and risks in light of the COVID pandemic. It analyses links between human infectious diseases and nature and what we know about how diseases (zoonoses) can transfer from animals to humans.

The report (which I wrote) argues laboratory procedures (including “gain of function” research) should be recognised as one potential driver of zoonotic “spillover”.

The term “gain of function” applies to the functional consequences of changes in the genetic makeup of an organism, including viruses. Such changes can be harmless, or even beneficial. They can occur naturally, when organisms mutate and evolve.

But experiments to deliberately induce mutations are increasingly done in laboratories. In that context, gain of function generally refers to attempts to confer greater transmission and/or virulence to a virus.

Supporters of such research argue it promises to help us be better prepared for pandemics. They acknowledge risks, but argue these can be managed by the use of highly regulated secure laboratories. Others maintain that the potential risks are simply too high and this type of research should be banned.

Why gain-of-function research matters


How DNA discoveries led to ‘gain of function’ research

During the second world war, DNA (and later RNA) was identified as the key genetic molecule. DNA’s (and RNA’s) structure provides unique “instructions” for every living organism.

Within just three decades “recombinant” technology made it possible to splice together genetic material from different species. Today, this can be done with consummate ease.

Numerous benefits followed, such as the insertion of insulin-producing genes into bacteria. This enabled cheaper, large-scale production of this hormone, essential to treat type I diabetes.

A 2019 report valued the market in therapeutics, mostly arising through recombinant genetic technologies, at more than US$315 billion (A$490 billion). The use of crops genetically engineered to resist disease is also increasing.

However, this type of research also sparked debate and concern.

A key figure in this emerging technology was Paul Berg, a biochemist who shared the 1980 Nobel Prize. Berg’s early work focused on modifying the SV-40 virus, known to be involved in tumour growth. Berg abandoned an experiment, inserting SV-40 into a bacterium, for fear, expressed by “many colleagues” that the newly created organism might infect humans, causing cancer.

For the next few decades, scientists navigated the complex ethics and developing technology around gene splicing, under increasingly secure conditions to limit foreseeable biohazard risks.

Bird flu

Then, in 2011, researchers performed experiments with a bird flu virus called H5N1. The virus killed an alarming percentage of humans diagnosed with it. Its saving grace was that it had very poor human-to-human transmission.

Controversy arose when two teams of researchers explored and found ways to make H5N1 transmissible between mammals. After first genetically modifying H5N1 researchers performing “serial passage” experiments in a mammalian model (ferrets) to see if they could further adapt it for mammalian to transmission. They succeeded.

Although it wasn’t clear the virus would be as deadly in humans, critics worried this new strain might escape (even from highly secure labs) and cause millions of deaths.

These concerns led US authorities to delay the studies’ full publication and to later restrict funding guidelines. This was intended to reduce genetic experiments perceived as risky.

Bans imposed, lifted and re-imposed

A brief, voluntary ban on such research was introduced then lifted in 2012. This type of work was generally called “dual use” because it may be intended for good but could be either misused for harm or inflict harm poorly due to bad luck.

However, lapses in US biosecurity in 2014 strengthened the case for a more careful stance. A US ban on funding for such work was imposed later that year. This time it was not voluntary. Also in 2014, the Cambridge Working Group declaration called for a global ban on work that might lead to the creation of “potential pandemic pathogens”.

Supporters of unfettered genetic research continued to insist the benefits outweighed the risks. They also said the risks were manageable if research was conducted in highly secure laboratories. In 2017, the US ban was overturned.

Now COVID

Today, COVID has magnified anxiety around this type of genetic research, irrespective of the pandemic’s true origin.

In September, the World Health Organization published a framework to help scientists mitigate biorisks and govern dual-use research of concern. It recognised that gain of function of concern is a real issue, with potentially catastrophic consequences. Global biosecurity expert Raina MacIntyre has discussed these concerns recently.

The National Health and Medical Research Council recently completed a review of Australian gain of function research. Such research relies on the integrity of researchers and that all such work must be done in an appropriately safe environment. Approval is also needed from a central authority.

My ongoing work argues we may be nearing a return to an earlier, more cautious approach to biorisks. In our globally connected context, the potential risks are just too high.

Is New Zealand foreign policy “independent?” (and related issues).

Is NZ foreign policy “independent?” (and related issues). – 36th Parallel Assessments

For many years New Zealand elites have claimed to have an “independent” foreign policy, so much so that it has become a truism of NZ politics that transcends the partisan divide in parliament and is a shibboleth of the NZ foreign policy establishment that is parroted by media and pundits alike. But is it a correct characterization? More broadly, is any country able to maintain a truly independent foreign policy?

If “independence” in foreign policy is defined as the unfettered freedom and ability to pursue courses of action in the international arena without regard to cost or consequence, then the answer is no. Foreign policy independence is an aspirational goal (for some) rather than a practicable achievement (for very few).

Instead, what NZ has is a flexible foreign policy based on what can be called constrained or bounded autonomy. Just like the notion of bounded rationality in game theory (where rationality is not opened-ended but framed by the interactive context in which decisions are made), NZ’s foreign policy autonomy occurs within identifiable parameters or frameworks governing specific international subjects and relationships that are not fungible or identical in all instances. Some are broad and some are limited in scope. Some are more restrictive and some are looser in application. Some are more issue-specific or detailed than others depending on the frameworks governing them. Within those parameters NZ has a significant range of foreign policy-making choice and hence room to maneuver on the world stage.

One reason that NZ does not have an independent foreign policy is that NZ is inserted in a latticework of formal and informal international networks and relationships that to varying degrees constrain its behavior. Things like membership in TPPA, 5 Eyes, WTO, IMF, WHO, NPT, COP, World Bank, INTERPOL and other multinational agencies as well as regional organizations like the Pacific Island Forum, Five Powers Agreement, NATO partnership and various international conservation and legal regimes, as well as bilateral agreements such as the NZ-PRC FTA, Washington and Wellington Agreements and Australia-NZ close defense relations, clearly demonstrate that NZ has formal and informal commitments that bring with them (even if self-binding) responsibilities as well as opportunities and privileges. What they do not bring and in fact mitigate against is foreign policy independence.

This latticework of relationships is the foundation for NZ’s commitment to a rules and norms-based international order because as a small country operating in a world dominated by great and medium powers, it is the commitment and enforcement of international codes of conduct that balances the relationships between big and small States. That gives NZ a measure of institutional certainty in its foreign relations, something that consequently grants it a degree of autonomy when it comes to foreign policy decision-making.

This is what allows NZ, in the broader sense of the term, to be flexible in its foreign policy. Within its broadly autonomous and flexible position within an international system governed by an overlapping network of rules, regulations and laws, comes the “nested” (as in “nested “ games as per rational choice theory, where the broadest macro-game encompasses a series of “nested” meso- and micro-games) ability to move between approaches to specific issues in a variety of areas in the diplomatic, economic and security spheres.

A second reason that NZ does not have an independent foreign policy is due to what international relations theorists call the “Second Image” effect: the influence of domestic actors, processes and mores on foreign policy-making. NZ’s foreign policy is heavily dominated by trade concerns, which follow mercantilist, Ricardian notions of comparative and now competitive advantage. The logic of trade permeates NZ economic thinking and has a disproportionate influence on NZ foreign policy making, at times leading to contradictions between its trade relations and its support for liberal democratic values such human rights and democracy. As trade came to dominate NZ foreign policy it had a decided impact at home, with the percentage of GDP derived from import-export trade averaging above 50 percent for over three decades (with a third of the total since 2009 involving to PRC-NZ trade).

Meanwhile, the domestic ripple effect of trade-related services expanded rapidly into related industries (e.g., accounting, legal and retail services related to agricultural export production), adding to its centrality for national economic well-being. As things stand, if NZ was to be cut off from its major trading partners (the PRC and Australia in particular), the economic shock wave would wash over every part of the country with devastating consequences.

What this means in practice is that export sector interests have a disproportionate influence on NZ’s foreign policy-making. The country’s material dependence on trade in turn locks in pro-trade mindsets amongst economic and political elites that either subordinate or inhibit consideration of alternative priorities. That reduces the freedom of action available to foreign policy-makers, which reduces their independence when it comes to formulating and implementing foreign policy in general. Almost everything passes through the filter of trade, and questions about trade are dominated by a narrative propagated by actors with a vested interest in maintaining the trade-dependent status quo.

Althugh less influential than the export-import sector, other domestic actors also place limits on foreign policy independence. Disapora communities, the intelligence and military services, tourism interests, religious groups, civil society organizations—all of these work to influence NZ’s foreign policy perspective and approaches. Balancing these often competing interests is an art form of its own, but the key take-away is that the influence of domestic actors makes it impossible for NZ to have a truly “independent” foreign policy for that reason alone, much less when added to the international conditions and frameworks that NZ is subject to.

Given those restrictions, the key to sustaining foreign policy flexibility lies in being principled when possible, pragmatic when necessary and agile in application. Foreign policy should be consistent and not be contradictory in its implementation and requires being foresighted and proactive as much as possible rather than short-sighted and reactive when it comes to institutional perspective. Crisis management will always be part of the mix, but if potential crises can be foreseen and contingency scenarios gamed out, then when the moment of crisis arrives the foreign policy-making apparatus will better prepared to respond agilely and flexibly.

In short, NZ has and should maintain a flexible foreign policy grounded in support for multilateral norms and institutions that allows for autonomous formulation and agile implementation of discrete positions and approaches to its international relations and foreign affairs. Whether it can do so given the dominance of trade logics in the foreign policy establishment remains to be see.

The big picture.

The issue of foreign policy independence matters because the world is well into the transition from unipolarity (with the US as the hegemon) to multipolarity (which is as of yet undefined but will include the PRC, India and the US in what will eventually be a five to seven power constellation if the likes of Japan, Germany and other States emerge to prominence). Multipolar systems are generally believed to be more stable than unipolar systems because great powers balance each other on specific issues and obtain majority consensus on others, which avoids the diplomatic, economic and military bullying (and response) often associated with unipolar “hegemonic” powers. However, the transition from one international system to another is marked by competition between rising and declining great powers, with the latter prone to starting wars in a final ttempt to save their positions in the international stats quo.

In the period of long transition and systemic realignment uncertainty is the new normal and conflict becomes the default systems regulator because norm erosion and rules violations increase as the old status quo is challenged and the new status quo has yet to be consolidated. This leads to a lack of norm enforcement capacity on the part of international organizations rooted in the old status quo, which in turn invites transgressions based on perceived impunity by those who would seek to upend it. This has been seen in places like the South China Sea, Syria, and most recently Ukraine.

The transitional moment is also marked by conflicts over the re-defining of new rules of systemic order. These conflicts may or may not lead to war, but the overall trend is the replacement of the old system (unipolar in the last instance) with something new. Illustrative of this is the Russian invasion of Ukraine, where a former superpower well into terminal decline has resorted to war on a smaller neighbor as a last attempt to hold on to Great Power status. No matter what the outcome of the conflict itself, Russia will be much diminished by its misadventure and therefore will not be a member of the emerging multipolar configuration.

The new multipolar order will include traditional “hard” and “soft” power usage but will also include “smart” and “sharp” power projection (“smart” being hybrids of hard and soft power and “sharp” being a directed focus by State actors on achieving specific objectives in foreign States via directed domestic influence and hybrid warfare campaigns in those States).

They core feature of the emerging multipolar system is balancing. Great Powers will seek to balance each other on specific matters, leading to temporary alliances and tactical shifts depending on the issues involved. They will then seek the support of smaller States, creating alliance constellations around individual or multilateral positions.That is why systemic multipolarity is best served when odd numbers of Great Powers are present in the configuration, as this allows for tie-breaking on specific subjects, to include rules and norms re-establishment or consolidation.

In multipolar systems balancing becomes both a focus and a feature of State behaviour (i.e. States seek to balance each other on specific issues but also desire to achieve an overall balanced system of interests in the multipolar world). In a sense, multipolar balancing is the diplomatic equivalent of the invisible hand of the market: all actors may wish to pursue their own interests and influence the system in their favour, but it is the aggregate of their actions that leads to systemic equilibrium and international market clearing.

In a nutshell: although international norms violations are common and conflict becomes the default systems regulator during periods of international transition and systemic realignment, the multipolar constellation that emerges in its wake is chracterised by balancing as both a focus and a feature. That demands flexibility and agility on the part of great powers but also gives diplomatic space and opportunity to smaller powers with such traits.

In this context a flexible and agile foreign policy approach allows a small State such as NZ considerable room for maneuver, may magnify its voice regarding specific areas of concern (such as climate change, environmental security, migration and the general subject of human rights, including indigenous and gender rights) and therefore give it increased influence disproportionate to its size and geopolitical significance (in other words, allow it to genuinely “punch above its weight”).

Issues for New Zealand.

On the emerging international system.

If a flexible and agile foreign policy is pursued, NZ has the ability to expand its diplomatic influence and range of meaningful choice in the emerging system. For self-interested reasons, NZ must push for the early consolidation of a new multipolar order dominated by liberal democracies, recognizing that there will be authoritarian actors in the arrangement but understanding that a rules-based international order requires the dominance of liberal democratic values (however hypocritically applied at times and always balanced by pragmatism) rather than authoritarian conceptualisations of the proper world order. In practice this means extending the concept of “liberalism” to include non-Western notions of cooperation, consensus-building, transparency and proportional equality of participation and outcomes (this is seen in the current NZ government’s inclusion of “Maori Values” in its policy-making orientation). The need for univerally binding international rules and norms is due to the fact that they help remove or diminish power asymetries and imbalances that favor Great Powers and therefore level the playing field when it comes to matters of economic, cultural, diplomatic and security import. For this reason and because it is a small State, NZ has both a practical reason to support a rules-based international order as well as a principled one.

NZ and the PRC-US rivalry.

The key to navigating US-PRC tensions is to understand that NZ must avoid the “Melian” Dilemma:” i.e., being caught in the middle of a Great Power conflict (the phrase comes from the plight of the island-state Melos during the Peloponnesian Wars, where Melos attempted to remain neutral. Sparta agreed to that but Athens did not and invaded Melos, killed its men, enslaved women and children and salted its earth. The moral of the story is that sometimes trying to remain neutral in a bigger conflict is a losing proposition).

NZ will not have a choice as to who to side with should “push come to shove” between the US and PRC (and their allies) in a Great Power conflict. That choice will ultimately be made for NZ by the contending Powers themselves. In fact, in a significant sense the choice has already been made: NZ has publicly stated that it will stand committed to liberal international values, US-led Western security commitments and in opposition to authoritarianism at home and abroad. While made autonomously, the choice has not been made independently. It has been forced by PRC behaviour (including influence, intimidation and espionage campaigns in NZ as well as broader misbehavior such as its record of intellectual property theft, cyber-hacking and the island-building projects in the South China Sea) rather than NZ’s desire to make a point. Forced to preemptively choose, it is a choice that is principled, pragmatic if not necessarily agile in application.

How much to spend on defense?

Focus on overall Defense spending (however measured, most often as percentage of GDP) is misguided. What matters is not how much is spent but how money is spent. Canada, for example, spends less (1.3 percent) of GDP than NZ does (1.6 percent) even though it a NATO member with a full range of combat capabilities on air, land and sea. The 2 percent of GDP figure often mentioned by security commentators is no more than a US demand of NATO members that is most often honoured in the breach. Although it is true that Australians complain that NZ rides on their coattails when it comes to defense capabilities, NZ does not have to follow Australia’s decision to become the US sheriff in the Southern Hemisphere and spend over 2.5 percent/GDP on defense. Nor does it have the strategic mineral resource export tax revenues to do so. Moreover, even if it overlaps in places, NZ’s threat environment is not identical to that of Autsralia. Defense priorities cannot be the same by virtue of that fact, which in turn is reflected in how the NZDF is organized, equipped and funded.

NZ needs to do is re-think the distribution of its defense appropriations. It is a maritime nation with a land-centric defense force and limited air and sea power projection capabilities. It spends the bulk of its money on supporting this Army-dominant configuration even though the Long-Term Issue Brief recently issued by the government shows that the NZ public are more concerned about non-traditional “hybrid” threats such as disinformation, foreign influence operations (both State and non-state, ideologically-driven or not), climate change and natural disasters as well as organized crime, espionage and terrorism. This is not to say that spending on security should completely shift towards non-traditional, non-kinetic concerns, but does give pause to re-consider Defense spending priorities in light of the threat environment in which NZ is located and the political realities of being a liberal democratic State where public attention is focused more on internal rather than external security even if the latter remains a priority concern of security and political elites (for example, with regard to sea lanes of communication in the SW Pacific and beyond). That leads into the following:

Trade.

Trade is an integral component of a nation’s foreign policy, particularly so for a country that is unable to autonomously meet the needs and wants of a early 21st consumer-capitalist society. The usual issue in play when it comes to foreign trade is whether, when or where trade relations with other countries should directly involve the State, and what character should such involvement adopt. Should it be limited to the imposition of tariffs and taxes on private sector export/imports? Should it be direct in the form of investment regulations, export/import controls, and even State involvement in negotiations with other States and private commercial interests? Should the overall trade orientation be towards comparative or competitive value? Most of these questions have been resolved well in NZ, where the government takes a proactive role in promoting private sector NZ export business but has a limited role beyond that other than in regulatory enforcement and taxation.

One change that might help erode NZ foreign policy subordination to trade-focused priorities is to either separate the Trade portfolio from the Foreign Affairs Ministry or to create a Secretariat of Trade within Foreign Affairs. In the first instance “traditional” diplomacy can be conducted in parallel to trade relations, with consultative working groups reconciling their approaches at policy intersection points or critical junctures. In the second instance Trade would be subordinated to the overarching logic of NZ foreign affairs and act as a distinct foreign policy component much like regional and subject-specific branches do now. The intent is to reduce foreign policy dependence on trade logics and thereby better balance trade with other diplomatic priorities.

The larger issue that is less often considered is that of “issue linkage.” Issue linkage refers to tying different threads of foreign policy together, most often those of trade and security. During the Cold War trade and security were closely related by choice: security partners on both sides of the East-West ideological divided traded preferentially with each other, thereby solidifying the bonds of trust and respect between them while benefitting materially and physically from the two dimensional relationship. NZ was one of the first Western countries to break with that tradition, and with its bilateral FTA with the PRC it completely divorced, at least on paper, its trade from its security. That may or may not have been a wise idea.

In wake of events over the last decade, NZ needs to reconsider its position on issue linkage.

Issue linkage does not have to be bilateral and does not have to involve just trade and security. Here again flexibility and agility come into play across multiple economic, diplomatic and military-security dimensions. For example, NZ prides itself on defending human rights and democracy world-wide. However in practice it has readily embraced trade relations with a number of dictatorial regimes including the PRC, Saudi Arabia, the UAE, Qatar, Iran, and Singapore (which whatever its veneer of electoral civility remains a one party-dominant authoritarian State). It also provides developmental aid and financial assistance to nobility-ruled countries like Samoa and Tonga. The question is how to reconcile these relationships with the professed championing of democracy and human rights?

Closed Five Link Chain Knots.

It is not an easy question to answer, and is where the “pragmatic when necessary” perspective clashes with the “principled when possible” approach. It might be the case that human rights and democracy can (some might say should) not be linked to trade. But that would mean ignoring abuses of worker’s rights and other violations like child labour exploitation in trading partners. It is therefore a complicated dilemma that might best be resolved via NZ support for and use of multinational organizations (like the ILO and WTO ) to push for adherence to international standards in any trade pact that it signs.

Alternatively, in the emerging post-pandemic system of trade a move to replace “off-shoring” of commodity production with “near-shoring” and even “friend-shoring” has acquired momentum. Near-shoring refers to locating production centers closer to home markets, while friend-shoring refers to trading with and investing in countries that share the same values when it comes to upholding trade and after-entry standards, if not human rights and democracy. Combining the post-pandemic need to de-concentrate commodity production and create a broader network of regional production hubs that can overcome the supply chain problems and negative ripple effects associated with the pandemic shutdown of production in the PRC, NZ could engage in what are known as mini-lateral and micro-lateral initiatives involving a small number of like-minded regional partners with reciprocal trading interests.

Australia and the Pacific.

Rather than get into specifics, here a broad appraisal is offered.

Australia is NZ’s most important international partner and in many aspects very similar to it. However, beyond the common British colonial legacy and shared Anglophone war experiences they are very different countries when it comes to culture, economy and military-diplomatic outlook. Likewise, NZ shares many traits with other Pacific island nations, including the seafaring traditions of its indigenus peoples, but is demonstrably distinct in its contemporary manifestation. More broadly, Austalia acts as the big brother on the regional block, NZ acts a middle sister and the smaller island States act as younger siblings with their own preferences, attitudes and dispositions.

To be clear: the family-like characterisation is a recognition of the hierarchical yet interdependent nature of the relationships between these States, nothing more. For NZ, these relationships represent the most proximate and therefore most immediate foreign policy concerns. In particular, the English speaking polynesian world is tied particularly closely to NZ via dispora communities, which in many cases involves NZ-based islanders sending remmitances and goods to family and friends back home. Island nations like Samoa and Tonga are also major recipients of NZ developmental aid and along with the Cook Islands are significant tourist destinations for New Zealanders.

Because of their extensive trade relationship and long-standing diplomatic and military ties, NZ understands that maintaining warm relations with Australia is vital to its national interests.

Where it can differentiate itself is in its domestic politics, offering a more inclusive and gentler form of liberal democratic competition that avoids the harder edged style displayed by its neighbor. It can include a different approach to immigration, refugee policy, indigenous rights, and the role of lobbyists and foreign influence in domestic politics, especially when it comes to political finance issues. Without being maudlin, NZ can be a “kinder, gentler” version of liberal democracy when compared to Australia, something that allows it to continue to work closely with its Antipodean partner on a range of mutal interests.

The key to maintaining the relationship with Austalia is to quibble on the margins of bilateral policy while avoiding touching “the essential” of the relationship.For example, disputes about the expulsion of Kiwi-born “501” criminal deportees from Australia to NZ can be managed without turning into a diplomatic rift. Conversely, combating foreign influence campaigns on local politics can be closely coordinated without extensive diplomatic negotiation in order to improve the use of preventative measures on both sides of the Tasman Sea.

The key to maintaining good relations with Pacific Island states is to avoid indulging in post-colonial condescension when it comes to their domestic and international affairs. If NZ truly believes in self-determination and non-interference in domestic affairs, then it must hoor that belief in practice as well as rhetorically. Yet, there has been a tendency by NZ and Australia to “talk down” at their Pacific neighbors, presuming to know what is best for them. There are genuine concerns about corruption in the Pacific community and the increased PRC presence in it, which is believed to use checkbook and debt diplomacy as well as bribery to influence Pacific Island state leaders in a pro-Chinese direction. But the traditionally paternalistic approach by the Antipodean neighbors to their smaller brethern is a source of resentment and has backfired when it comes to contanining PRC expansion in the Southwestern Pacific. The reaction to the recently announced Solomon Islands-PRC bilateral security agreement is evidence of that heavy-handedness and has been met with hostility in the Solomons as well as other island States at a time when the regional geopolitical balance is in flux.

To be sure, NZ offers much developmental aid and humanitarian assistance to its island neighbors and is largely viewed with friendly eyes in the region. The best of way of assuring that goodwill is maintained is to speak to island States as equals rather than subordinates and to emphasize the notion of a Pacific community with shared traditions, cultures and values. It is for the Pacific Island states to determine what their individual and collective future holds, and NZ must respect that fact even while trying to promote principles of democracy, human rights and transparency in government region-wide.

Summary.

It is mistaken and counter-productive to label New Zealand’s foreign policy as “independent.” A cursory examination of domestic and international factors clearly demonstrates why it is not. Instead, NZ purses a flexible foreign policygrounded in constrained or limited autonomy when it comes to foreign policy-making and which is operationalized based on agility when it comes to reconciling relationships with other (particularly Great) powers and manuevering between specific subjects. It is soft and smart power reliant, multilateral in orientation and predominantly trade-focussed in scope. It champions ideals tied to Western liberal values such as human rights, democracy, transparency and adherence to a rules based international order that are tempered by an (often cynical) pragmatic assessment of how the national interest, or least those of the foreign policy elites, are served.

Balancing idealism and pragmatism in non-contradictory or hypocritical ways lies at the core of NZ’s foreign policy dilemmas, and on that score the record is very much mixed.

New Zealand scored C+ for physical activity in children and teens – what’s driving this and what can be done?

C+ – that’s Aotearoa New Zealand’s overall grade in the most comprehensive global assessment of physical activity in children and adolescents. Even more worryingly, the 57 participating countries scored a D average overall.

The Active Healthy Kids Global Alliance’s Global Matrix 4.0 used ten indicators related to physical activity to score countries’ performance. The findings are consistent with earlier assessments and show children and adolescents around the world are not moving enough to promote healthy growth and development.

The report’s authors say young people worldwide have formed new habits “in response to the new normal, provoked by a socially accepted screen-centric indoor living society, exacerbated by the COVID-19 pandemic, global conflicts and severe weather associated with climate change”.

Aotearoa’s grade was better than the global average because of our high rates of participation in organised sports and physical activity, where we tied for fifth place (B-), compared with a C- overall.

An indicator that scores government initiatives related to physical activity placed Aotearoa at the top of all countries, in part thanks to Ihi Aotearoa/Sport NZ’s development of a national outcomes framework and Waka Kotahi’s programme to make streets safer for people, rolled out in early 2020.

A dismal D for active transport

Despite these investments, Aotearoa had one of the lowest grades for active transport (D), with only five countries performing more poorly. This is in keeping with a trend of low and declining active transport over the last decade.

Denmark and Japan topped the table for active transportation with an A-, compared with a C- average overall. Denmark noted their comprehensive networks of cycle lanes and their government’s persistent efforts to implement safe routes to school as key contributors to their success.

Research in Aotearoa with children, schools and whānau/families consistently shows we need improved traffic safety to facilitate active transport. There is a dearth of connected and safe cycling infrastructure across the country, resulting in extremely low rates of biking.

In earlier research we also identified safe road crossings as a priority and called for more signalised crossings and raised zebra crossings to slow traffic down. Initiatives to improve driver behaviour are also essential – speeding, inattentive driving, red-light running and failing to stop at pedestrian crossings are all common.

Other factors also come into play. School leadership and partnerships with community groups and agencies can both play an integral role in the success of initiatives that promote active transport. Ultimately, getting to and from school actively needs to be a safe and easy option.

It is worth noting that transformative changes have happened since we collated evidence for our report card, including the government’s NZ$350 million transport choices programme. But even when better active transport options are in place, it takes time for people to change how they travel. We can expect an increase in active transport to lag behind the completion of infrastructure.

Addressing inequities for adolescents

We have identified several inequities for young people in Aotearoa across all indicators.

We found striking differences for sedentary time across age groups, with the worst outcomes for rangatahi/adolescents in school years 11-13 (aged about 15-17 years). In this group, only 12% met the threshold of no more than two hours per day of recreational screen time, compared with 36% of those in school years 7-10 and 61% in years 0-6.

This teenage group was also less likely to report being active in physical education at school or to participate in organised sport (31% and 44% respectively), compared with younger children (years 0-10) whose rates were between 64%-74% for these indicators.

Active transport was also lower, at 22%, compared with 30% of children in school years 0-6 and 34% in years 7-10. Unsurprisingly, overall physical activity was also lower for those in school years 11-13, at 47% (C-), compared with around 60% for their younger counterparts.

Considering physical inactivity tracks from adolescence into adulthood, we urgently need effective mechanisms to facilitate activity in ways that work for adolescents.

It is likely the shift away from compulsory physical education from year 11 has a significant impact on school-based activity. Physical education and organised sports can also be unwelcoming and unsafe spaces for many young people, particularly if they don’t fit the norm, for example around athleticism and gender, (dis)ability and body size.

Adolescents are a diverse group with numerous competing priorities, notwithstanding the significant impact of transitioning through this life stage in the context of climate change and a global pandemic. Providing a range of safe and welcoming opportunities for physical activity that meet young peoples’ needs is essential.

Why am I bloated? Here are some possibilities to consider

If your tummy seems to feel full or stretched and is rumbling all the time, you’re not alone. Up to 30% of people of all ages experience bloating, with symptoms such as gassiness, a sense of fullness and pressure.

This can be with or without distention (a visible increase in abdominal girth).

So what might be behind your bloating?




Read more:
A poo dose a day may keep bipolar away. When it comes to mental health, what else could poo do?


The role of gas

Bloating is in fact a complex condition that can be caused by several direct and indirect factors. Gas often plays a role.

Gas production in the digestive system is part of the normal digestion process, and is released through the mouth (burps) or anus (farts).

On average, our gas expulsion is around 600–700 millilitres per day, resulting in around 14 farts a day. That said, there isn’t a set number for the normal amount of gas or expulsions; each body is different.

Bloating can occur as a result of retained gas, excess gas production, altered gas transit (changes in the speed and movement of gas), or intestinal hypersensitivity.

An imbalanced gut microbiome can lead to the overproduction of gas.

What is the human microbiome?

We have more than 40 trillion microbes living in and on our body. They can be helpful or harmful. The balance between these helpful and harmful microbes plays an important role in our immune response, metabolism and health.

These bacteria need food to survive. Their food comes from fermenting carbohydrates such as dietary fibre from the plants we eat.

One of the byproducts of this fermentation process is hydrogen gas.

Most of these microbes live in the lower parts of our intestine (colon). The upper parts of the intestine (small intestine) have far fewer microbes.

But if an excessive number of microbes colonise the small intestine (a condition known as small intestine bacterial overgrowth), more gas is produced in the small intestine.

This can lead to bloating, abdominal discomfort, diarrhoea and nausea.

Could it be IBS, lactose issues or FODMAPs?

Some disorders of the intestine and colon can affect the amount of gas and severity of bloating symptoms.

For example, in constipation, movement of stools is reduced, allowing more time for the bacteria to ferment the stool content, increasing gas production.

Bloating is also very common in people with irritable bowel syndrom (IBS).

Changes in gut muscle tone and greater sensitivity to gas contribute to bloating in IBS sufferers.

Bloating may also occur because of poor digestion and malabsorption of some carbohydrates.

Lactose malabsorption (in those with lactose intolerance) is a common issue.

Milk is poured into a bowl of cereal.
Lactose malabsorption (in those with lactose intolerance) can cause gut problems for some people.

Symptoms may also occur with other digestive resistant short-chain carbohydrates known as FODMAPs (fermentable oligo-, di-, monosaccharides and polyols).

FODMAPs are found in a wide variety of foods, including certain fruit and vegetables, grains and cereals, nuts, legumes, lentils and dairy foods.

While these are good foods for our gut bacteria, they can add to gas production and trigger bloating symptoms, especially in people with digestive disorders (like IBS). They can also cause water to be drawn into the intestines, causing distension. This can contribute to bloating.

Other factors: salt, hormones or swallowing air

There are of course other factors that could be behind bloating.

For example, consuming too much sodium or salt in your diet causes water retention, resulting in abdominal distention. But this may also alter the gut microbiome and influence gas production.

For many women, bloating can be linked to the menstrual cycle phase. This is most common at the onset of bleeding, when peak fluid retention occurs, but is also related to underlying hormonal changes.

Swallowing too much air, especially when eating, can also increase the amount of gas entering the gastrointestinal tract and lead to bloating.

Talking while eating, eating in a rush, and carbonated beverages can also increase the amount of air swallowed.

How can I reduce bloating?

Dietary strategies can be effective ways of managing bloating. While foods that trigger symptoms can be different for everyone, you could try to:

  • eat fewer gas-producing FODMAP foods such as onion, cabbage, brussels sprouts, cauliflower, dried beans and lentils

  • eat fewer foods containing lactose, like milk, ice-cream and some yoghurts (there are lactose-free alternatives for people with intolerance)

  • replace carbonated drinks such as soft-drinks with water, and drink less alcohol

  • consume more probiotics (such as yoghurt or certain fermented foods)

  • do more exercise, as mild physical activity enhances intestinal gas clearance and can reduce symptoms of abdominal bloating

  • eat and drink more slowly; taking your time means you can enjoy your food, but will also help you swallow less air.

See an accredited practising dietitian for personalised advice on managing symptoms using dietary strategies.

When to see a GP

Most of the time, bloating goes away soon enough and is no cause for concern. But consider seeing a doctor if:

  • your gas is persistent and severe and it’s impacting your quality of life

  • your gas is associated with other symptoms such as vomiting, diarrhoea, constipation, unintentional weight loss or blood in the stool.

The G20 may be a talk fest, but it’s a talk fest we need at a time of growing division

Source: The Conversation (Au and NZ) – By Tom Chodor, Lecturer in Politics and International Relations, Monash University

Last Friday, Australian Prime Minister Anthony Albanese jetted off for a marathon of international summits, the most significant of which will be the G20, held in Bali.

Forged during the 2008 Global Financial Crisis (GFC) – allegedly on Kevin Rudd’s own initiative – the G20 brings together 20 of the world’s largest economies, styling itself as the premier forum for international economic cooperation.

While attention focuses on the annual leaders’ summit, much of the G20’s work happens quietly behind the scenes, with economic ministers and officials meeting throughout the year under a rotating presidency to address global economic challenges.

Yet, this is probably not why you’ve heard of the G20 recently. Rather, the focus has been on Vladimir Putin. Since Russia invaded Ukraine, Western leaders have made it clear they would not accept sitting in the same room as Putin. Yet, the host, Indonesian President Joko Widodo, has rejected calls to disinvite Russia, offering a compromise by also inviting Volodymyr Zelensky, even though Ukraine is not part of the G20.

Jokowi’s stance stems partially from the nature of the G20 – it’s not a “by invitation” organisation – and partially to do with Indonesia. The country has a proud history of geopolitical non-alignment, and its position is actually closer to the rest of the Global South. While critical of the war, developing countries don’t see it in such existential terms as the West, and have called for a negotiated solution that would involve compromises on both sides.

Nevertheless, the fiasco over Putin has frustrated the Indonesians, who saw it as ruining their big moment on the international stage. In the end, Putin solved the problem by deciding to stay home, sending his Foreign Minister Sergei Lavrov instead. Nevertheless, Lavrov is likely to get an icy reception. Last time he met with his G20 counterparts, he walked out after facing criticism over the war.

Can the G20 can actually make progress on its policy agenda?

There’s plenty to deal with. The pandemic has wrecked the global economy – crippling supply chains, slowing global trade and leaving numerous developing countries on the verge of bankruptcy.

More recently, Russia’s invasion of Ukraine has created a global energy crisis and runaway inflation, prompting central banks to drastically raise interest rates. This, however, has only increased global financial volatility, as investors flood to the US bond market, triggering an arms race over rates.

All this is adding up to what the International Monetary Fund is predicting will be a bad 2023 for the global economy, with around one third of countries likely to enter recession, including, potentially, Australia.

Yet, the G20 is unlikely to make much progress on these issues. The summit comes at a time of deep divisions between the world’s powers, not only over Russia-Ukraine, but also between the US and China, the US and its Middle Eastern allies, and within the EU following the surge of populist parties in places such as Italy.

In this context, there’s little consensus on how to address these problems. It seems the best the G20 can hope for is to try to stabilise these tensions by offering world leaders a chance to meet and talk face to face.

The main event will be the meeting between US President Joe Biden and China’s Xi Jinping, their first as leaders. Again, there’s plenty to discuss: China’s sabre rattling over Taiwan, the human rights abuses in Xinjiang, the continuing tariffs on China’s exports imposed by Donald Trump, and Biden’s more recent efforts to effectively kill off China’s computer chip industry.




Read more:
Clampdown on chip exports is the most consequential US move against China yet


Don’t expect much progress on these thorny issues, which are at the core of a fledgling Cold War between the two superpowers. But at the very least, the aim will be to take the tensions down a notch or two, and see if cooperation is still possible in areas of mutual interest, like climate change.

Thawing the relationship with China

Australia is also aiming for its own rapprochement with China. Albanese confirmed he’ll be meeting with Xi on Tuesday afternoon, the first such meeting since 2017. The new Labor government has worked behind the scenes to thaw the relationship put in the diplomatic freezer under the Coalition, following spats over foreign interference and the origins of the COVID-19 pandemic.

Albanese will be asking for a removal of $20 billion worth of tariffs on Australia’s exports, as well as pushing for the release of two Australians currently imprisoned on spurious spying charges.

China has its own sources of discontent, not least the AUKUS pact, and the recently announced expansion of the military facilities in Darwin to make them capable of hosting US B52 bombers. The two sides are also locked in an escalating competition over influence in the Pacific, with Solomon Islands as the biggest flashpoint.

Again, it’s unlikely these issues will be resolved in Bali, given the two countries are at opposite sides of the Cold War standoff. Still, it’s good to talk; the last six years have shown how the lack of regular dialogue leads to escalating tensions.

It seems that in a world of fragmenting power blocs, rising tensions and deepening economic crisis, creating a platform for the biggest players to talk is the best the G20 can do.

What’s the connection between cosmetic procedures and mental health?

Source: The Conversation (Au and NZ) – By Gemma Sharp, NHMRC Early Career Senior Research Fellow, Monash University

Although we cannot be sure of the exact numbers of Australians undergoing cosmetic procedures, as there is no requirement for health professionals to report their statistics, there is a consensus demand is on the rise.

In 2015, the Cosmetic Physicians College of Australasia found Australians were spending more than $1 billion a year on non-invasive cosmetic procedures like Botox and fillers. This is more than 40% higher, per capita, than in the United States.

In the US, where procedure statistics are reported, there was a 42% increase in the number of filler procedures and a 40% increase in Botox procedures performed in the last year alone.

Rates of mental health issues in this group may be higher than the general population, but seemingly not enough is being done to ensure the psychological safety of people requesting cosmetic procedures.

Thinking of getting a minor cosmetic procedure like botox or fillers? Here’s what to consider first


Body dysmorphic disorder

Body image concerns are generally the main motivator for seeking cosmetic procedures of all kinds. These concerns are usually focused on the body part where the cosmetic intervention is sought, such as the nose for a rhinoplasty.

Severe body image concerns are a key feature of several mental health conditions. The most prevalent in people seeking cosmetic procedures is body dysmorphic disorder. In the general community, around 1-3% of people will experience body dysmorphic disorder, but in populations seeking cosmetic surgery, this rises to 16-23%.

Rates of body dysmorphic disorder are much higher in populations seeking cosmetic surgery.

Body dysmorphic disorder involves a preoccupation or obsession with one or more perceived flaws in physical appearance which are not visible or seem minor to other people. In response to the distress regarding the flaw, the person with body dysmorphic disorder will perform repetitive behaviours (such as excessively checking body parts in the mirror) and mental acts (such as comparing their appearance with other people).

These concerns can have a significant negative impact on the person’s daily life, with some people too distressed to leave their home or even eat dinner with family members out of fear of being seen by others.

With the distress associated with body dysmorphic disorder seemingly stemming from physical appearance issues, it makes sense someone with body dysmorphic disorder is far more likely to turn up at a cosmetic clinic for treatment than a mental health clinic.

The problem is, cosmetic intervention usually makes the person with body dysmorphic disorder feel the same or worse after the procedure. They may become even more preoccupied with the perceived flaw and seek further cosmetic procedures.

Patients with body dysmorphic disorder are also more likely to take legal action against their treating cosmetic practitioner after believing they have not received the result they wanted.

For these reasons, body dysmorphic disorder is generally considered by health professionals to be a “red flag” or contraindication (a reason not to undergo a medical procedure) for cosmetic procedures.

However, this is not entirely clear-cut. Some studies have shown people with body dysmorphic disorder can improve their symptoms after cosmetic intervention, but the obsession may just move to another body part and the body dysmorphic disorder diagnosis remain.

What about other mental health conditions?

Body dysmorphic disorder is by far the most well-studied disorder in this area, but is not the only mental health condition that may be associated with poorer outcomes from cosmetic procedures.

Recent studies have found rates of mental illness are higher among cosmetic patients.
philippe spitalier/unsplash, CC BY

According to a recent systematic review, the rates of depression (5-26%), anxiety (11-22%) and personality disorders (0-53%) in people seeking cosmetic surgery may be higher than the general population (which are estimated to be 10%, 16% and 12% respectively).

However, these rates should be interpreted with some caution as they depend greatly on how the mental health diagnosis was made – clinician-led interview (higher rates) versus mental health questionnaire (lower rates). Some interview approaches can suggest higher rates of mental health issues as they may be quite unstructured and thus have questionable validity compared with highly structured questionnaires.

Besides body dysmorphic disorder, the research investigating other mental health conditions is limited. This may just be due to the fact body image focus is at the core of body dysmorphic disorder, which makes it a logical focus for cosmetic surgery research compared with other types of psychiatric disorders.

So what should happen?

Ideally, all cosmetic surgeons and practitioners should receive sufficient training to enable them to conduct a brief routine assessment of all prospective patients. Those with signs indicating they are unlikely to derive psychological benefit from the procedure should undergo a further assessment by a mental health professional before undergoing the procedure.

This could include an in-depth clinical interview about motivations for the procedure, and completing a range of standard mental health questionnaires.

If a person was found to have a mental health issue in the assessment process, it does not necessarily mean the mental health professional would recommend against pursuing the procedure. They may suggest a course of psychological therapy to address the issue of concern and then undergo the cosmetic procedure.

At the moment, assessments are only recommended rather than mandated for cosmetic surgery (and not at all for injectables like Botox and fillers). The guidelines say evaluation should be undertaken if there are signs the patient has “significant underlying psychological problems”.

This means we are relying on the cosmetic medical practitioner being capable of detecting such issues when they may have received only basic psychological training at medical school, and when their business may possibly benefit from not attending to such diagnoses.

An August 2022 independent review by the Australian Health Practitioner Regulation Agency and the Medical Board of Australia recommended the guidelines around mental health assessment should be “strengthened” and emphasised the importance of medical practitioners receiving more training in the detection of psychiatric disorders.

Ultimately, as cosmetic practitioners are treating patients who are seeking treatment for psychological rather than medical reasons, they must have the wellbeing of the patient front-of-mind, both out of professional integrity and to protect themselves from legal action. Mandatory evaluation of all patients seeking any kind of cosmetic procedure would likely improve patient satisfaction overall.

Effects of climate change such as flooding makes existing disadvantages for Indigenous communities so much worse

Source: The Conversation (Au and NZ) – By Toni Hay, Expert in Indigenous climate adaptation, Indigenous Knowledge

Spring is here, and with it comes the threat of more floods. Australia is currently experiencing its third consecutive year of a La Niña weather cycle. This means we expect more rainfall than average over the spring and summer months. There is heightened risk of floods, tropical cyclones, prolonged heatwaves and grass fires in southern Australia. This has already led to flooding in parts of the country, and communities are now bracing for more bad weather.

According to the Human Rights Council Report 75-80% of the world’s population will be negatively impacted by climate change. It also states climate change will exacerbate existing poverty and inequality and have the most severe impact on our poor.

Indigenous people in Australia make up just 3.8% of the population. Still, they account for nearly 30% of those living in poverty and up to 50% in remote communities.

Some Indigenous people live in poor and/or overcrowded housing. These properties are often not prepared for natural disasters or the effects of climate change such as persistently hotter temperatures. In addition, there is limited nearby infrastructure or resources to prepare for and respond to emergencies.

All levels of government have been criticised for a lack of action in supporting Indigenous communities during times of crisis. This now needs to be addressed urgently, given the destructive weather is forecast to continue in the coming months.

Past disasters have shown First Nations people are more vulnerable

Earlier this year, when floods hit the town of Lismore in New South Wales, the local Indigenous community was left to fend for themselves, with many people losing their homes and possessions. First Nations communities were among those worst affected, with many people stranded without access to food or clean water.

This disaster shone a light on the disparities between First Nations communities and the rest of Australia when it comes to preparedness for natural disasters. While federal, state and local government provide some support such as emergency services, there is often a lack of disaster prevention measures achieved through thorough planning that is available for these communities.

As of August, six months after the disaster, there were still 1,296 people homeless in the northern NSW region, 500 of whom were First Nations people. First Nations people have been disproportionately affected by this disaster, with many still struggling to find permanent housing.

The Parliamentary flood report has found SES and Resilience NSW failed Lismore communities after the floods. A major failing has been the lack of planning and preparation, as we are seeing again this spring.

The parliamentary flood report for NSW has 37 recommendations, it does not include culture or culturally safe resources as outlined below. The United Nations Disaster Risk Reduction recommends including the whole Indigenous community and two-way information sharing.

Two-way information sharing means that information flows not only from government and other outside agencies to Indigenous communities, but also from Indigenous communities to government and other agencies. This ensures everyone has a better understanding of disaster risks faced by the community and can work together to develop more effective and culturally appropriate mitigation and response strategies.

Like many disasters in Australia, Aboriginal people are over-represented and under-resourced in the NSW floods


We need Indigenous-led disaster strategies

Disaster risk reduction plans must be designed in a way that takes into account peoples’ needs and cultural values. This includes ensuring that evacuation efforts do not result in displacement, and relief and recovery programmes are tailored to meet the specific needs of Indigenous communities. This would mean finding ways to evacuate communities that don’t take them too far from Country, if their preference is to remain nearby.

First Nations communities need adequate funding to implement local disaster reduction plans inclusive of culture. They also need access to professionals who specialise in culturally inclusive climate adaptation and disaster risk reduction program development. Indigenous-led initiatives are often more effective than externally imposed programs at reducing disaster risk. This is because they are better able to consider Indigenous communities’ specific needs and vulnerabilities. Supporting Indigenous peoples with access to resources to achieve this is also essential for them to effectively lead and participate in disaster risk management efforts.

Researchers Wanhui Huang and Sadahisa Kato found success with communities in the Philippines and Bangladesh developing disaster risk reduction plans. These countries’ local governments opted to move communities to higher ground nearby instead of evacuating them to a distant place.

These plans were developed after it was realised that communities forced from their homes more than once a year were not only losing their homes and belongings, but also access to health centres, children’s education, and areas with cultural significance to reduce the complex impacts on physical and mental health as well as well-being which is far more than has been observed after single disasters.

By moving these communities to higher ground before a disaster strikes, local governments hope to help ease the transition of evacuation by minimising the disruption to people’s lives.

Here in Australia, Indigenous peoples must be included in local, state and national disaster risk reduction policies and plans. This is essential to ensure their rights and needs are respected and considered in prevention and response to natural disasters.

Indigenous peoples have a wealth of traditional knowledge and experience that can be invaluable in disaster risk reduction efforts. These knowledges are often based on a deep understanding of the local environment and can provide practical insights into reducing disaster risk.

Indigenous peoples have 65,000 years of resilience in the face of natural disasters, which can inform disaster risk-reduction strategies. It is vital these communities have a voice in decision-making about disaster response and recovery efforts. Through this we can effectively reduce the risks associated with extreme weather through an inclusive and comprehensive approach.

At least 700,000 years ago, the world’s largest sand island emerged as the barrier that helped the Great Barrier Reef form

Source: The Conversation (Au and NZ) – By James Shulmeister, Professor and Head of School of Earth and Environment, University of Canterbury, and Adjunct Professor, The University of Queensland

Scientists had always been puzzled why the Great Barrier Reef formed long after Australia had conditions suitable for reef growth. It turns out the answer might be K’gari (Fraser Island).

K’gari, the world’s largest sand island and a UNESCO World Heritage Area, juts out from the Australian coastline where the continent extends furthest east. It lies at the northern end of one of the world’s largest and longest longshore drift systems. If not for the presence of K’gari, the sand carried by this system would continue to migrate northward directly into the area of the Great Barrier Reef, which starts a little north of the island.

The volumes of sand carried along the coast are immense. It is estimated 500,000 cubic metres of sand moves north past each metre of shoreline every year.

K’gari plays a key role in delivering this sand to the deep ocean. Sand moving along its eastern beaches is directed across the continental shelf and into the deep immediately north of the island. The dominant south-easterly trades would drive sand all the way into the full tropics if K’gari did not direct it off the shelf.

Our research, published today, has established the age of K’gari as being older than the Greater Barrier Reef. This suggests the reef became established only after the island protected it from the northward drift of sand.

The northernmost point of K’gari, Sandy Point, marks where the sand heads deeper underwater, moving along the continental shelf before dropping off the edge.

Why does the reef depend on the island?

The southern limit of the Great Barrier Reef is not a result of the climate being too cool further south. Corals can and do grow many hundreds of kilometres further south in places like Moreton Bay (Brisbane) and Lord Howe Island.

The main limiting factor for the southern extent of the reef is the drowning of corals by the rivers of sand going north. The corals in places like Moreton Bay occur where they have a hard substrate to grow on and are sheltered from sediment inundation.

The sand comes from sediment delivered to the Tasman Sea via the Hawkesbury and Hunter rivers in mid-New South Wales. Prevailing south-easterly breezes and their associated coastal wave systems sweep these sediments north for more than 1,000 kilometres.

The geological setting of eastern Australia is rather stable, so this longshore drift system should have been in operation for many millions of years. The Great Barrier Reef corals could not have survived without some protection from this northward flow of sand.

The techniques we used to establish the age of the coastal dune fields of K’gari and the adjacent Cooloola Sand Mass on the mainland south of K’gari show the first coastal dunes date to about 1 million years ago. The modern dune fields were established by 700,000-800,000 years ago. Prior to 1 million years and definitely prior to 700,000-800,000 years ago, sand would have drifted north into the region of the modern barrier reef.

Why did K’gari form at that time?

This timing coincides with a major geo-astronomical event, the Mid-Pleistocene Transition. At this time Earth’s glacial cycles changed from a period of about 40,000 years to about 100,000 years. This change had a major impact on global sea levels because the longer cycles supported the growth of larger ice caps during cold periods.

Prior to this transition, global sea levels went up and down about 70 metres between warm (interglacial) and cold (glacial) periods. Afterwards, the range increased to 120-130m.

Under a longshore drift system some sediment “leaks” out into deeper water where currents and waves are not strong enough to move it. A drop of 70m would still leave the South-East Queensland coastline on the continental shelf. So, before the Mid-Pleistocene Transition, sand moving north would be gradually stored on the outer parts of the continental shelf, potentially accumulating over millions of years.

Once the first 100,000-year cycle occurred, sea levels would have dropped to the outer edge of the continental shelf. During the start of the next warm period, rising sea levels would erode the accumulated sands and transport it shoreward. This would drive a major period of dune building along the coast.

This was a major event because sediment accumulated over millions of years was added back into the sedimentary system. The very different dune types associated with plentiful sand are recorded in the oldest parts of the cliff sections at Cooloola and K’gari.

Again, remnants of dunes formed when sea levels were low are preserved directly off this coastline. We have shown a major pulse of sand was released into the dune systems formed during the earliest high sea-level periods of the 100,000-year climate cycles.

How does that line up with the age of the reef?

K’gari was constructed in its “modern” form between about 1 million and 700,000 years ago. Once it was in place, any further sand driven up the coast during interglacial high sea levels was lost to deep water off the north of K’gari.

The last piece of the puzzle is the age of the Great Barrier Reef. For a heavily investigated natural wonder, this is remarkably poorly defined, but the oldest evidence dates the reef to about 650,000 years ago.

In short, coral reef development appears to not have started until sediment drift from the south was blocked off. In this way the whole of the east coast of Australia is linked together as a single story and K’gari has played a key role in the formation and protection of the Great Barrier Reef.

Just like the satire in The White Lotus, tourism campaigns often perpetuate colonial stereotypes about the countries they are selling

Source: The Conversation (Au and NZ) – By Philippa Chandler, Research Fellow, The University of Melbourne

HBO

The TV series The White Lotus has returned for a second season. Both series of The White Lotus explore the underbelly of resort tourism.

The first series is set in a resort in Hawaii and contains sex, drugs and outrageously selfish behaviour. Through its focus on the interactions between wealthy American guests and local resort staff, it explores complex themes including racial inequality, the ongoing impacts of colonialism, debates about land ownership and identity politics.

The second series is set in Sicily, but the first season gives us an interesting opportunity to reflect on the way tourism destinations are marketed to appeal to wealthy tourists.

International tourism campaigns try to market the perceived “essence” of what makes a country special. In the process, they often perpetuate stereotypes. Critical tourism scholars have long argued such branding tends to overemphasise and essentialise cultural difference.

Many of the problems satirised by The White Lotus are perpetuated by a recent advertising campaign by Tourism Fiji.

The Bulanaires campaign launched in 2019 encourages international tourists to visit Fiji. The phrase Bulanaires blends the term “billionaires” with the Fijian greeting “bula”, which implies wishes of good health.

A key message in the campaign is that Fijians may not be wealthy yet are “rich in happiness”.




Read more:
Fiji is officially ‘open for happiness’ – will that apply to its tourism workers too?


The Bulanaires campaign is sophisticated, well-produced and full of charm and humour. However, our research into tourism tropes shows the advertising campaign also recycles some troubling stereotypes about Fijian people.

Firstly, like much advertising for the Pacific region and alongside a suite of related colonial stereotypes, the campaign romanticises poverty as a form of wellbeing. Secondly, it uncritically reinforces the colonially entrenched notion of the “happy native”.

The ‘happy native’ and the ‘smiling servant’

As they greet the incoming guests at the beginning of season one, the staff at The White Lotus are encouraged to “wave like they mean it” by their manager and to project “vagueness” to the visitors. This sense of blending into the background and performing the role of the subservient and smiling host is apparent in tourism advertising too.

In one Tourism Fiji advertisement, a smiling resort worker says to the camera “what makes me happy is seeing you happy”. Fijians are cast as the epitome of authentic happiness: pre-existing, pervasive and spontaneously felt and expressed.

The notion that all Fijians are authentically happy despite wealth disparities stems from, and reinforces, longstanding colonial tropes of the “happy native” being somehow free from the stressors of the rat race. Such fantasies are widely applied beyond the Pacific region. As tourism academic Camille O’Reilly writes, these include “a nostalgic and naïve view of the “traditional” life found outside the West, untouched by modernity but now rapidly disappearing.“

The question is not whether Fijians feel happy, but rather what the implications are of broadcasting these stereotypes of Fijian wellbeing to tourists.

The irony is that low paid work in the tourism industry often entangles them at the bottom of the capitalist hierarchy they are marketed as being untouched by.

Poverty and wellbeing

The awkward juxtapositions of wellbeing and poverty are explored in series one The White Lotus via Jennifer Coolidge’s character Tanya, a wealthy and lonely tourist who tries to forge a relationship with her Hawaiian massage therapist.

The relationship veers further towards exploitation when Tanya hints she could invest in the massage therapist’s business, on the unspoken understanding the therapist pay her additional attention. The pairing – and the ultimately unrealised investment – highlights the uneven economic circumstances between the women. What constitutes “wellbeing” for the tourist can erode the host’s wellbeing.

The relationship between wellbeing and poverty is awkwardly apparent in the Tourism Fiji campaign, which suggests Fijians are happy, despite being far poorer than tourists. It goes even further to suggest poverty even enables happiness.

“We don’t get many billionaires around here” smiles a local in the advertisement, “but we have plenty of BULANAIRES!”

The advertisement exploits the lexicon of wellbeing and mindfulness to reassure tourists the Fijians who bring them their cocktails and look after their children are content with low wages.

Selling the connection to nature

National branding campaigns for Fiji, Vanuatu, Papua New Guinea and the Solomon Islands all depict Indigenous peoples as living somehow closer to nature than those who might wish to travel to visit them.

The advertising campaign Answer The Call To Vanuatu is a good example.

“The call” connects tourists to Vanuatu by evoking a sense of existential loss and longing. It features a conch shell trumpet sounding from an “untouched paradise” across the ocean and the internal voice of a prospective tourist crying out for adventure. It is selling escape from the rigours of everyday life, healing through connection to nature and a sense of human authenticity.

For locals, however, “answering the call” has nationalist connotations reminiscent of wartime recruitment campaigns. This message was perpetuated during COVID-19 travel bans where tourism campaigns hailed tourists through wistful narratives about future holidays, in which “the time will come to connect again” and, meanwhile, Indigenous people will “keep it beautiful for you”.

The White Lotus is a cleverly-written reminder about the colonial underpinnings of international tourism. It shows the ways in which the tourism industry is often bolstered by problematic cultural stereotypes; often complicit in widening the gap between rich and poor, visitors and hosts.

Chokepoint Capitalism: why we’ll all lose unless we stop Amazon, Spotify and other platforms squeezing cash from creators

Source: The Conversation (Au and NZ) – By Rebecca Giblin, ARC Future Fellow; Associate Professor; Director, Intellectual Property Research Institute of Australia, The University of Melbourne

In 2020, the independent authors and small publishers whose audiobooks reach their readers via Audible’s ACX platform smelled a rat.

Audiobooks were booming, but sales of their own books – produced at great expense and well-reviewed – were plummeting.

Some of their royalty statements reported negative sales, as readers returned more books than they bought. This was hard to make sense of, because Audible only reported net sales, refusing to reveal the sales and refunds that made them up.

Perth-based writer Susan May wondered whether those returns might be the reason for her dwindling net sales. She pressed Audible to tell her how many of her sales were being negated by returns, but the company stonewalled.

Then, in October 2020, a glitch caused three weeks of returns data to be reported in a single day, and authors discovered that hundreds (and even thousands) of their sales had been wiped out by returns.

Suddenly, the scam came into focus: the Amazon-owned Audible had been offering an extraordinarily generous returns policy, encouraging subscribers to return books they’d had on their devices for months, even if they had listened to them the whole way through, even if they had loved them – no questions asked.

Encouraged by the policy, some subscribers had been treating the service like a library – returning books for fresh credits they could swap for new ones. Few would have realised that Audible clawed back the royalties from the book’s authors every time a book was returned.

Good for Amazon, bad for authors

It was good for Amazon – it helped Audible gain and hold onto subscribers – but bad for the authors and the performers who created the audiobooks, who barely got paid.

Understanding Amazon’s motivation helps us understand a phenomenon we call chokepoint capitalism, a modern plague on creative industries and many other industries too.

Orthodox economics tells us not to worry about corporations dominating markets because that will attract competitors, who will put things back in balance.

Five ways to boost Australian writers’ earnings


But many of today’s big corporations and billionaire investors have perfected ways to make those supposedly-temporary advantages permanent.

Warren Buffett salivates over businesses with “wide, sustainable moats”. Peter Thiel scoffs that “competition is for losers”. Business schools teach students ways to lock in customers and suppliers and eliminate competition, so they can shake down the people who make what they supply and buy what they sell.

Locking in customers and creators

Amazon is the poster child for chokepoint capitalism. It boasts of its “flywheel” – a self-described “virtuous cycle” where its lower cost leads to lower prices and a better customer experience, which leads to more traffic, which leads to more sellers, and a better selection – which further propels the flywheel.



But the way the cycle works isn’t virtuous – it’s vicious and anti-competitive.

Amazon openly admits to doing everything it can to lock in its customers. That’s why Audible encourages book returns: its generous offer only applies to ongoing subscribers. Audible wants the money from monthly subscribers and wants the fact that they are subscribed to prevent them from shopping elsewhere.

Paying the people who actually made the product it sells a fair share of earnings isn’t Amazon’s priority. Because Amazon founder Jeff Bezos’ famous maxim is “your margin is my opportunity”, the executive who figured out how to make authors foot the bill for retaining subscribers probably got a bonus.

Another way Audible locks customers in is by ensuring the books it sells are protected by digital rights management (DRM) which means they are encrypted, and can only be read by software with the decryption key.




Read more:
The US government is trying to stop the merger of two of the world’s biggest publishers – but will it help authors?


Amazon claims DRM stops listeners from stealing from creators by pirating their books. But tools to strip away those locks are freely available online, and it’s easy for readers who can’t or won’t pay for books to find illegal versions.

While DRM doesn’t prevent infringement, it does prevent competition.

Startups that want to challenge Audible’s dominance – including those that would pay fairly – have to persuade potential customers to give up their Audible titles or to inconveniently maintain separate libraries.

In this way, laws that were intended to protect against infringement of copyright have become tools to protect against infringement of corporate dominance.

Once customers are locked in, suppliers (authors and publishers) are locked in too. It’s incredibly difficult to reach audiobook buyers unless you’re on Audible. When the suppliers are locked in, they can be shaken down for an ever-greater share of what the buyers hand over.



How a few big buyers can control whole markets

The problem isn’t with middlemen as such: book shops, record labels, book and music publishers, agents and myriad others provide valuable services that help keep creative wheels turning.

The problem arises when these middlemen grow powerful enough to bend markets into hourglass shapes, with audiences at one end, masses of creators at the other, and themselves operating as a chokepoint in the middle.

Since everyone has to go through them, they’re able to control the terms on which creative goods and services are exchanged – and extract more than their fair share of value.

The corporations who create these chokepoints are trying to “monopsonise” their markets. “Monopsony” isn’t a pretty word, but it’s one we are going to have to get familiar with to understand why so many of us are feeling squeezed.

Monopoly (or near-monopoly) is where there is only one big seller, leaving buyers with few other places to turn. Monopsony is where there is only one big buyer, leaving sellers with few other places to turn.

There’s an obvious reason wages aren’t growing, but you won’t hear it from Treasury or the Reserve Bank


In our book, we quote William Deresiewicz, a former professor of English at Yale University, who points out in his book The Death of the Artist that “if you can only sell your product to a single entity, it’s not your customer; it’s your boss”.

Increasingly, it is how the creative industries are structured. There’s Audible for audiobooks, Amazon for physical and digital versions, YouTube for video, Google and Facebook for online news advertising, the Big Three record labels (who own the big three music publishers) for recorded music, Spotify for streaming, Live Nation for live music and ticketing – and that’s just the start.

But as corporate concentration increases across the board, monopsony is becoming a problem for the rest of us. For a glimpse into what happens to labour markets when buyers become too powerful, just think about how monopsonistic supermarkets bully food manufacturers and farmers.


Scribe Publications

A fairer deal for consumers and creators

The good news is that we don’t have to put up with it.

Chokepoint Capitalism isn’t one of those “Chapter 11 books” – ten chapters about how terrible everything is, plus a conclusion with some vague suggestions about what can be done.

The whole second half is devoted to detailed proposals for widening these chokepoints out – such as transparency rights, among others.

Audible’s sly trick only finally came to light because of the glitch that let authors see the scope of returns.

That glitch enabled writers, led by Susan May, to organise a campaign that eventually forced Audible to reform some of its more egregious practices. But we need more light in dark corners.

And we need reforms to contract law to level the playing field in negotiations, interoperability rights to prevent lock-in to platforms, copyrights being better secured to creators rather than publishers, and minimum wages for creative work.

These and the other things we suggest would do much to empower artists and get them paid. And they would provide inspiration for the increasing rest of us who are supplying our goods or our labour to increasingly powerful corporations that can’t seem to keep their hands out of our pockets.

Australia is considering a ban on cyber ransom payments, but it could backfire. Here’s another idea

Source: The Conversation (Au and NZ) – By Jeffrey Foster, Associate Professor in Cyber Security Studies, Macquarie University

First Optus, now Medibank; in less than two months we’ve experienced two of the largest personal data breaches in Australia’s history. In both cases the hackers attempted, and failed, to extort a ransom in exchange for not releasing personal data.

So far the Optus hackers have released only a small sample of data, and claim to have deleted the rest. On the other hand, the Medibank hackers have released the records of more than one million people – and have threatened to release more data on Friday.

Medibank hackers are now releasing stolen data on the dark web. If you’re affected, here’s what you need to know


With this looming threat, the Australian government is looking to bolster its cybersecurity defences — including through a taskforce set up to retaliate against the Medibank hackers.

Minister for Cyber Security Clare O’Neil has said the government is also considering making ransom payments to cybercriminals illegal. The idea has picked up steam – but would this cure be worse than the disease?

The response to the Medibank hack

The group behind the latest Medibank hack, currently being called “BlogXX”, has been linked to Russian cybercriminal organisations by the Australian Federal Police. It has known links to the notorious REvil cyber gang (which was dismantled by Russia’s Federal Security Service in January).

Large-scale cybercriminal gangs are able to extort high ransom payments from their victims. During REvil’s arrest, authorities seized the equivalent of A$12.8 million in cash, $7 million in crytpocurrency and 20 luxury cars.

There are multiple ways to decrease the profitability of data breaches for criminal organisations. The first is to make hacks more difficult, making it more time-consuming for the hackers to break into computers.

This could be achieved by increasing fines for organisations that fail to follow best practices in cybersecurity – a privacy reform that was recently introduced in Australia and has passed through the lower house.

A second potential solution is to make ransomware payments illegal in Australia. Under some circumstances, it may already be illegal for Australian organisations to pay a ransom, such as if the payment funds further criminal or terrorist activity of groups under sanction by the United Nations.

However, the attribution of cyberattacks is difficult, and it’s not always possible to know whether paying a particular group would be a crime. An organisation may pay a ransom, only to find out much later it has broken the law.

When banning ransom payments works

The idea of banning ransom payments isn’t new. In April, Nigeria criminalised ransom payments to kidnappers. However, not paying kidnap ransoms in Nigeria has also resulted in deaths, which suggests this approach may end up punishing victims.

Still, survey results show citizens and cybersecurity experts are generally in favour of banning ransomware payments. In a recent survey of UK residents by security firm Talion, 78% of respondents from the general public supported a ban, as did 79% of cybersecurity professionals.

A ban on ransom payments could quickly reduce the profits racked up by criminal gangs targeting Australia.

In cases like the recent Optus and Medibank hacks, where the ransom was demanded to “not leak” sensitive information, banning ransom payments may be a good idea. It could take the burden of making a decision away from the organisation targeted, and mitigate the public’s judgment of that decision.

It would also reduce (but not entirely remove) the possibility of criminals receiving ransom payments – and therefore make their operations less profitable.

The problems with a ban

However, unlike the Optus and Medibank breaches, many ransoms are paid to unlock encrypted computers. Some ransomware attacks involve the hackers encrypting all of the computers, data and backups a company has. Failing to restore those data can, in many cases, cause the business to collapse.

In such instances, banning ransom payments may discourage organisations from declaring breaches. They may pay the ransom to be able to move on with business – even if it is a crime. Should this happen, it would reduce the overall transparency of reporting on breaches, and could lead to hackers blackmailing victims to not divulge the hack.

This particular concern has led the US Federal Bureau of Investigation to recommend to the US Senate Judiciary Committee to not ban all ransom payments.

For a ban on ransom payments to be effective, the penalties for paying the ransom would need to be more severe than the impact of the ransom itself. If the penalties are inadequate, organisations may simply pay the ransom and deal with the legal consequences so they can move on with normal operations.

An alternative solution

Cyberinsurance policies often provide reimbursement for ransomware payments. In fact, it’s a common tactic for cybercriminals to demand a ransom equivalent to the insurance reimbursement. While this means the organisation suffers fewer losses, the cybercriminals still profit.

A more nuanced approach may be to ban cyberinsurance reimbursements for ransom payments, which would reduce the overall percentage of breaches that result in a payment. This could reduce profits for criminal gangs, while still allowing a company to salvage its operations under the worst-case scenarios.

The decision to ban or not to ban ransomware payments is complicated, and a blanket ban is likely to cause more problems than it fixes. We need change, but the best solution would be a case-by-case approach.

In the end, these kinds of cybercrimes are unlikely to be eradicated by any single policy change. They will require a wide range of policies, laws and regulations that each chip away at specific problems. If we do this, eventually the cost to criminals could outweigh the profits.

Tempted to buy a UV light disinfection gadget? Some can be dangerous – here’s what you need to know

The COVID-19 pandemic has fundamentally changed many of our behaviours and attitudes towards infection control.

Hand hygiene was one of the earliest and most adopted measures to counteract the spread of disease, but there have been more technology-based approaches, too.

Vodka won’t protect you from coronavirus, and 4 other things to know about hand sanitizer


One example is the booming industry of devices that use ultraviolet radiation (UV) to kill germs. While UV can successfully sanitise the air, or objects such as your smartphone, it can also come with cancer risk if the radiation is not behind a proper barrier.

Here’s what you need to know about UV sanitation devices.

How does UV sanitation work?

Ultraviolet light is light with wavelengths just short enough that most humans can’t see it under normal conditions. The most ubiquitous source of UV is the Sun, which radiates everything from vacuum UV to far UVC, UVC, UVB and UVA rays (see below).

The last two can pass the ozone layer in our atmosphere, while the first three are blocked – good news for life on Earth, since UVC in particular can be harmful to living things.

A chart showing the wavelengths of ultraviolet light
Ultraviolet light is invisible to the eye, and spans from 10 to 400 nanometres in wavelength.

At a wavelength of 250–260 nanometres, energy generated by UVC rays can penetrate through microbes to break their DNA and RNA, disrupting their cell functions and killing them.

This is useful for germicidal (germ-killing) UVC radiation technology, although its efficacy depends on radiation intensity, the distance from light source to target, the type of surface being sanitised, and the wavelength at which the UVC is operating.

The blue light you often see on such devices is either decorative, or the visible light emitted by the chemicals used to produce UVC – remember, the UV light itself is invisible.

According to research, sanitation devices that emit high doses of germicidal UVC are an efficient means of killing fungi, viruses, bacteria and protozoa – single-celled organisms. They have been successfully used in treating water, air, sewage, for food safety, medical settings, public transport and more.

The key is to have the UVC source fully enclosed and automatically stop if the device is open, so there’s no risk of exposing people to the radiation, which can cause severe burns and even increase the risk of cancer.

UV sanitation gadgets that operate without enclosure present serious health risks. Unfortunately, current lack of regulation means such devices are readily available for consumers to buy – and potentially be harmed by.

A serious lack of regulation

Numerous companies have researched and developed safe, efficient and fully enclosed UVC devices.

However, the market is unregulated, with serious concerns about the quality and safety of some dubious devices available for consumers. In 2020, the lighting industry body Global Lighting Association raised its concerns:

“[I]n the midst of a global COVID-19 epidemic, GLA is concerned at the proliferation of UVC disinfecting devices – particularly being sold on the internet – with dubious safety features and inadequate safety instructions”.

Ultraviolet light can make indoor spaces safer during the pandemic – if it’s used the right way


UVC products without enclosure, such as the “disinfection wands” you might see on the internet, can be very unsafe. They can affect exposed skin, eyes and mucous membranes.

Due to health risks, any non-enclosed UVC device should only be remote-controlled or automatic. It should also be equipped with safeguards, such as a sensor that turns it off if it detects anyone in the room.

To ensure the safety and efficacy of UVC devices available on the consumer market, we need watchdog bodies to urgently introduce rigorous global regulations.

Is far UVC safer?

Recently, far UVC has been proposed as a possible solution to this challenge. Radiating at a wavelength of 207–222 nanometres, far UVC has a “shallow” skin entrance. However, the research with far UVC is very recent and so far mostly focused on animals.

Very few human studies have been performed, and some have been funded by companies prototyping far UVC devices, which can introduce a bias. Literature search reviews report different analytic parameters, which makes comparisons difficult to interpret.

Some trials have started, but there are few to date, and with small sample sizes.

We will need trials with rigorous ethical approvals to investigate the full far UVC impact on humans. There is a lack of understanding how far UVC might affect people with thinner outer skin layers, affected by cuts, light sensitivity, or various medical conditions.

Ultraviolet radiation is a strong disinfectant. It may be what our schools, hospitals and airports need


What to look out for if you still want a UV sanitation device

When it comes to buying a UVC gadget, buyer beware. Never buy anything that claims you can disinfect hands, the body, or a whole room while people are around. Skin cancers like basal cell carcinoma and squamous cell carcinoma are attributed to UV exposure.

Check the documentation. Is there evidence the device is effective against microorganisms? What’s the length of exposure, and how far from the source is the target being sanitised?

You also need to be aware that the cost of efficient and safe new technology and efficient UVC-producing LEDs is very high. Therefore, you may need to question the effectiveness of a relatively “cheap” device.

In the absence of a global regulatory body within the UVC market, the rule of thumb is to purchase only a fully sealed, enclosed UVC device operating with strict safety and efficiency to harm microbes, not you.

Pharmacists could help curb the mental health crisis – but they need more training

Chances are you live within 2.5 kilometres of a community pharmacy and visit one about every three weeks.

You don’t need an appointment. The wait time is usually short. These factors make pharmacists highly accessible healthcare professionals.

Pharmacists are regularly sought after for advice, including about mental health. In fact, pharmacists may be among the first health professional contacted about a health concern. They are also in regular contact with patients experiencing mental health issues or crises.

Despite the fact most pharmacists believe it is part of their role to provide mental health-related help, they may lack the confidence to respond to, raise or manage mental health issues with patients. In our recent study, pharmacists report not intervening about 25% of the time when they believe a patient is experiencing a problem or crisis.

Providing pharmacists with early intervention skills could help them address these challenges.

The pandemic has seen mental health decline

The COVID pandemic has seen anxiety and depression increase by 25% globally, signalling a broader mental health decline.

Poor mental health affects around 20% of the Australian population each year, and 44% of Australians over their lifetime. In a recent survey of 11,000 people, 24% of them said their mental health had declined over the previous six months.

Most concerning is that about 60% of people experiencing a mental health issue won’t seek help. This means people are more likely to remain undiagnosed and disconnected from support.

Pharmacists’ many hats

While dispensing and consulting are critical activities for pharmacists, they also help patients with questions and advice about their health, including their mental health.

Generally, pharmacists in Australia have high levels of mental health-related literacy and evidence-based treatments.

Despite this, pharmacists report a lack of confidence which prevents them from raising mental health issues with patients. This is possibly because only 29% of pharmacists in Australia have mental health crisis training.

A lack of confidence in raising and addressing mental health-related issues means patients are likely to remain undiagnosed, untreated, and unsupported.

4 key elements of mental health first aid

Many of us are familiar with first aid as immediate help offered to an injured or sick person. But what if the issue is not physical, but mental? Many people don’t know what immediate help they can offer.

As with physical injury or illness, timely and high-quality immediate help is critical.

There are a variety of not-for-profit and commercial mental health first aid training programs. A recent literature review of programs for mental health professionals suggests they can minimise stigma and increase knowledge. They can also bolster confidence and intentions to help.

Across the programs, there are four common elements to providing high-quality mental health first aid.

1. Recognise someone may be experiencing a mental health issue or crisis

Recognising a mental health issue or crisis involves taking notice of verbal, physical, emotional and behavioural indicators. Given pharmacists interact with patients about every three weeks, they may be in a good position to notice changes.

They may express sadness, anger, frustration, hopelessness, shame or guilt. Patients might say: “There’s no hope” or “I can’t go on like this”.

Physical indicators include fatigue, sleeping difficulties, restlessness, muscle tension, upset stomach, sweating, difficulty breathing, changes in appetite or weight.

Emotional indicators reflect how a person is feeling and include significant mood changes, teariness, agitation, anger, desperation or anxiety.

Symptom guides for anxiety, depression, bipolar disorder, and suicidal ideation are available.

2. Approach and assesses the person

Opening the dialogue can be as simple as, “How are you? I have noticed [symptoms] and am concerned.”

Your role is not to clinically diagnose a patient; however, it is valuable to assess the patient’s risk and level of urgency. Risk and urgency will help inform whether the person is in immediate danger or can use other non-urgent support services.

The TED acronym can guide first discussions in the following way:

Tell me …

Explain how that has been impacting you …

Describe what is happening …

3. Listen in an active way and communicate without judgement

Active listening involves confirming you are hearing and understanding the other person. Ways of doing this include: nodding, appropriate eye contact, and summarising what has been shared.

Communicating without judgement involves demonstrating genuine concern for the other person and talking about their experience.

Open-ended questions usually use “how” and “what” queries. You could say something like: “I’ve noticed some changes recently, what’s happening for you?” or “I see you are filling a prescription for sleep tablets. How are you sleeping?”

4. Refer the person to supports

People who are struggling with their mental health can benefit from sharing details with professionals, like general practitioners, or family and friends – but they might need encouragement to seek this support out.

The support system recommended should match the level of urgency. Urgent services include Lifeline for free 24-hour phone, chat, and text message support. The Suicide Call Back Service is also a free 24/7 counselling service.

If in doubt or in an emergency, dial 000.

Non-urgent and free online support is available from Head to Health, the Black Dog Institute and Beyond Blue.

Could training community pharmacists help?

Studies in Australia, New Zealand, Canada and abroad all point to pharmacists’ believing they need more training in mental health first aid.

Research suggests almost 70% of patients believe all pharmacists should have mental health first aid training. Patients report feeling significantly more comfortable speaking about mental illness with a pharmacist with this training.

And emerging evidence shows mental health first aid training can increase the quality of help provided by pharmacists.

In our study, we found Australian pharmacists with mental health first aid training were more likely to intervene than untrained pharmacists.

While the overall quality of the first aid provided by both mental health first aid trained and untrained pharmacists was high, some key differences existed. Trained pharmacists assessed patients and encouraged other supports (such as from friends and family) more. They also felt more confident discussing suicide risk.
