Climate change, heat, and a possible risk to infant and child health

I recently wrote to warn that players and spectators at events such as the Australian Open may unknowingly be placing their future as well as short term health at risk, due to exposure to levels of heat (up to 69 degrees C in the sun on the court enclosed by a vast stadium) which I think are unacceptable, particularly for players engaged in the most strenuous exercise that is imaginable. 

I also warned that some spectators, many of whom are far less fit and most of whom are older than the players, may also be at risk, even if not exercising and even if they are well hydrated.

But I would like to add that there is also a theoretical risk that pregnant women may be putting their unborn babies at risk, both in the womb and after birth, perhaps lifelong.

This hypothesis is plausible if the link between season of conception and foetal deaths is confirmed to be in part due to heat exposure. While that is currently uncertain there are suggestive data in support, such as an econometric paper. This found that additional days above 80°F (26.7°C) causes a "large decline in birth rates approximately 8 to 10 months later". The authors comment that air conditioning could be used to substantially offset the fertility costs of climate change, a suggestion which is unfortunately as yet too expensive for most of the world's people.

Pregnant women watching events such as the Australian Open, especially in very hot days and even more so if they are sitting in the sun, may therefore risk having a miscarriage. 

However, that is not the only risk. If we hypothesise that a certain "dose" of heat, a metric that combines air temperature, humidity, duration of exposure, clothing and exercise can lead to foetal death, then it follows that a lower dose of heat may cause subtle or even gross foetal abnormality, in infants exposed to a lower dose in utero. This would be analogous to my hypothesis, which I first originated in 2012, that frail, elderly and in other ways vulnerable people who do not die of prolonged heat exposure are likely to suffer from other effects, some of which could be long-lasting, especially if they accidentally fall during a period of recovery.

Furthermore, if there is a threshold of a heat "dose" then it is highly unlikely that one size fits all. The dangerous dose is likely to be influenced by many other factors: age, fitness, weight, other indicators of health status, genes, and perhaps, even month of birth. It is also likely that some stages of pregnancy are more vulnerable than others.

It has long been known that being born in autumn confers a higher life expectancy than being born in spring (at least in non-equatorial regions that have distinct seasons). Could heat in the first trimester be an under-recognised factor helping to explain this?

Of course, this is only speculation. It would require a great deal of study to be more sure. But, since 2012, research funds to study this and similar questions have been virtually unavailable in Australia. 

My recommendation to the organisers of the Australian Open is to hold the tournament in a later month. But that suggestion won't be taken seriously for many more years. For spectators who are pregnant or possibly pregnant - I suggest that they sit in the shade and drink lots of water. Wear a hat and bring a fan. Or perhaps consider staying at home if the temperature is too high. Yet, no one knows what temperature is too high. I suggest the risk is likely to be higher with higher temperatures and the relationship is likely to be non-linear, i.e. the additional risk between 43 °C and 42°C is likely to be more than between 21°C and 20°C. And, please, lobby a politician to treat global warming and climate disruption with the seriousness it deserves.

An early premonition: Sikkim, 1988

In 1987 (before BODHI was formally started) I was invited, with another Australian doctor, to visit Rumtek Monastery, in order to explore establishing a clinic there. We had a letter of invitation from the secretary of Tai Situ Rinpoche, one of the four "seat holders" caring for the Kagyu lineage while disciples waited for the reincarnation of His Holiness the Karmapa.

Rumtek is in Sikkim, then a restricted state of India, with only 3 days maximum permits being issued.

We applied at least 3 months in advance for the permit to go to Skikim. At that time of my life, being trusting, and also anticipating a long relationship with India, I thought it prudent to be absolutely honest, so my stated purpose was not tourism but something like “to discuss establishing a clinic”.

We were granted a visa, but no permit. We were told we might get the permit after arrival in India. In Kolkata (January 1988) we went to the famous “Writer’s Building” where clerks were dwarfed by vast piles of paper (few computers in India then). We were told, “no permit but you might get one in Darjeeling". We went to Darjeeling. There, a friendly official said “yes, you can have a permit - would you like one for 7 days?) (i.e. greater than twice the normal).  Well, we couldn’t, because we had booked a train to head towards Bodh Gaya, a few days later. But 3 days was fine.

Overjoyed, we caught a bus to Gangtok (Sikkimese capital). We arrived in the evening. Next day we explored Gangtok, waiting for the bus to Rumtek (about 15 kms away). With hindsight, I think the local police may already have been looking for us.

Gangtok: source

We caught the bus. We arrived at dusk. I felt exuberant. We were welcomed, we were fed. After about an hour at Rumtek I had one of the few genuine premonitions in my life, as if I could feel a shadow. Perhaps a minute later, four police arrived. They took us back to Gangtok. Its lights were strewn like stars on the hill across the valley. The police allowed us to sleep in a hotel that night, but we had to report to them the next morning and then stay continuously with them, although we were not formally arrested. Then they took us to board the commercial helicopter (at our own expense) back to Bagdogra, the airfield on the plains below Darjeeling. The only consolation was that the helicopter’s route was via western Sikkim, then completely off limits to tourists. We saw a famous golden monastery from the sky, probably Pemayangste. The governor of Sikkim was also on board. The police were quite excited about that, they said it was auspicious, and signified we would one day return.

When we eventually reached Delhi, we spent another day in a queue; eventually we saw an official. She was initially sympathetic. But then she found a file, and her attitude changed. She told us absolutely nothing. An official at the Australian High Commission also told us nothing.

I have not yet been back to Sikkim, I have not tried.

Climate disruption, extreme heat and sport

In recent weeks sportsplayers and health have been in the news. Last month, Suranga Lakmal, a fast-bowling cricketer from Sri Lanka, vomited in New Delhi, on field, due to air pollution and exercise. This month, English cricketer Joe Root retired ill, due to diarrhoea and extreme heat. Kato Ottio, a New Guinean rugby player died this month, after falling ill at football training. Cycle races in Adelaide have been truncated or rescheduled due to multiple days with shade temps in the mid-40s.

And this week, at the Australian Open, tennis players and tennis spectators are being exposed to unacceptable levels of heat with surface temperatures, in the sun, on some courts, approaching 70 degrees C.

I am sorry but it is time to reschedule the summer cricket, cycling and tennis to a cooler month, and similarly, time to recognise that dangerous climate change is no longer in the future. Climate disruption is here. Shifting the dates would be a form of adaptation. It would leave a big hole in our summer,'s entertainment, but it is unacceptable to treat athletes as guinea pigs for the pleasure of spectators, watching at home in air conditioned comfort. (That is, if the air conditioning and energy infrastructure can keep up.)

What we know about heat and health

There is a fair bit known about heat, humidity, the wet bulb temperature and that fit young men and women can easily die of heat stress. Dogs pant and elephants flap their ears in extreme heat; humans sweat. When sweat evaporates we lose a little heat, lowering our core temperature. We also have long known that humidity greatly increases the danger of heat, as in humid environments our sweat does not easily evaporate. Thus, sweating when it's humid is not as effective.

If the wet bulb temperature reaches 35 degrees C. then even a fit person will die, probably in just a few hours. Such wet bulb temperatures are still extremely rare, but by treating our atmosphere as an open sewer, as recommended by a legion of politicians, we are on track to make some parts of the world completely uninhabitable if we go outside. If you are not fit, you will probably die even sooner, and at wet bulb temperatures below 35 deg C.

We also know that people with pre-existing illnesses are more vulnerable to acute heat effects, manifesting within minutes, hours or perhaps days. We know that in the 2009 heatwave in Victoria, where 173 people died in bushfires, even more died in Melbourne from simple heat exposure. (See the Victorian Department of Health report.)

Acute (rapid onset) symptoms can be reduced and hopefully prevented by drinking, cooling and stopping exertion. Sports people can drink, apply ice, and maybe even have the roof lowered so there is shade - but they can't stop their exercise without losing.

Heat can, in some locations, especially cities, elevate exposure to troposphericic ozone, which harms lung function.

We have virtually no idea of the long term effects of excess heat

In contrast to the knowledge on acute exposure to extreme heat, we know next to nothing about the long term effects, other than some data on renal impairment and urinary tract stones due to prolonged dehydration, mainly affecting agricultural workers with inadequate water access. We also know a little about sudden, often mysterious deaths in exploited construction workers, particularly in the Middle East. But we know next to nothing about the life expectancy and other health indicators of those workers who do survive. (And we are not likely to - their employers will not welcome such studies.)

The starting position of those running the Australian Open appears to be that if a player or spectator survives symptomatic heat stress then their future health will be completely unaffected. But this may be wishful thinking. We don't even know that if someone who experiences extreme heat exposure, but is completely without symptoms, will be ok in the long run.

In fact, the converse is more plausible. It is, for example, highly likely that those who are vulnerable to heat (such as the elderly and those with pre-existing conditions, e.g. heart failure, dementia or many other severe chronic diseases) who do not die will have a step-like fall in their function, at least temporarily. Will they recover that full lost step? Over what period? How many will have a mishap, such as a fall, before they fully recover, in the weeks or months after the heat event? In the elderly, falls can be very serious, and often presage death.

It is also well-known that many multiple sclerosis (MS) patients experience a decline in function during heat - heat slows nerve conduction. Could excessive heat tip some people, previously unaffected, into neurological conditions, including migraine? (French tennis player Gael Monfils reported extreme dizziness at the Australian Open). We don't know. We do know that people at higher latitudes have more MS. The dominant explanation is that such people are exposed to more ultraviolet light, but could a factor be that, in part, over long periods of time, such people have sought to live in cooler conditions? Or perhaps that those with MS in very hot areas aren't able to have the same reproductive success?

Human bodies can be thought of as complex mixtures of chemicals and electrical signals. We have evolved to live in an "envelope" of temperature and humidity, an envelope many people are now exceeding. How do we know that proteins (or any other bodily component) repeatedly exposed to high temperatures will completely recover? Is that plausible?

"The healthy player effect"

Sure, we see champions like Roger Federer appearing to function well, despite the heat. But could there be a "healthy player effect"? That is, might we not learn a lot more about the adverse effects of extreme heat upon sportspeople by studying people who abandoned sport, or perhaps switched to a winter sport, due to their discomfort with heat? My former mentor, Tony McMichael, coined the term "healthy worker effect", recognising that studying the health of long-term factory workers told only a small part of the story.

The NH&MRC's failure to recognise the risk of chronic heat effects

Between 2012 and 2016 I repeatedly proposed research projects to investigate aspects of these questions, but with no success. The National Heath and Medical Research Council has declined to fund at least six large grant applications of relevance. (I was involved with five of them, one of which I led).


It is unconscionable to treat athletes and spectators in hot conditions as guinea pigs. Many emergency workers such as firefighters and military personnel have to endure such heat. We urgently need to better understand the long term risks that those workers face, and, if we find them, then try to work out ways they can be protected. However, until we know, spectators and athletes will be better protected by a change in the date of the Australian Open, cycle races, and in the near future, cricket.

Decades of denial and neglect about climate change, such as by former Australian Prime Minister  Tony Abbott (a keen cyclist), have created this crisis. Let us not compound that negligence. Ignorance is no defence. We have a duty of care to investigate chronic health effects of heat. I have a duty to add my voice about these many concerns.

Halfdan Mahler, primary health care, and the warm decade for social justice

This is an expanded version of an article in the (50th) issue of BODHI Times. This is the occasional newsletter of the NGOs BODHI and BODHI Australia which I co-founded in 1989. It is based on several sources, including an excellent open access article by Theodore Brown, Elizabeth Fee and Victoria Stepanova called "Halfdan Mahler: Architect and Defender of the World Health Organization “Health for All by 2000” Declaration of 1978".

A pastor's son, "disease palaces" and the origins of primary health care

Dr Halfdan Mahler, who died in December 2016, was the third Director-General of the World Health Organization (WHO). Brown et al summarise his development: "The youngest child of a Baptist preacher, Mahler chose medicine over preaching." After training in tuberculosis care and prevention "he led the Red Cross campaign against the disease in Ecuador, before joining WHO in 1951. Experience in India convinced him that public health resources in developing countries were biased toward hospital-based medical care and that these priorities had to change."

Socrates Litsios, in a long personal reflection on primary health care and Health for All provides two relevant anecdotes about Mahler, one about the unfair distribution of health resources, the second about the difficulties of reform (see green).

Mahler related the example of a developing country in which health was declared as “a   universal human right” but in which one found, in one province, “80 per cent of the health budget being used to support one teaching hospital, whereas in outlying parts complete coverage is supposed to be achieved by one general purpose dispensary for half a million people.”
"During his work in India, Mahler had become convinced that tuberculosis could be successfully treated with ambulatory (non-hospital based) care: “[we went] with tears in our eyes, to the Minister and we said ‘Madame Minister, now that we have shown this you will have to close down all your tuberculosis hospitals because we need the money in order to do ambulatory kind of treatment’ and she looked at me and said ‘you must be a crazy man, even an elephant would cry over your naivete. How do you think I as a politician can close down the hospitals, you must be mad’.”

Mahler before a Mercator's projection; an unfortunate choice, given his dedication to social justice!
Primary Health Care, Disease Palaces and David Morley

A term reflecting the problem Mahler had perceived is "disease palaces". Popularised (and probably coined) by another Christian, David Morley, this refers to the disproportionate concentration of health resources in one, or perhaps a handful, of fairly elaborate hospitals, in countries which are overwhelmingly poor. The problem is not that a poor nation should not have a halfway decent (or even a good) hospital; it is that the amount of human and financial capital that such a hospital demands leaves little (from the health budget) for basic sanitation, nutrition, health education and other aspects of primary health care. More background about disease palaces is in Morley's book "Paediatric Priorities in Developing Countries". Published in 1973, the same year that Mahler was elected as WHO Director General, it too is a product of what Mahler called “a warm decade for social justice".

I never had the fortune to meet Morley, but I acquired and read his book in 1985, the year I focused on the study of health in what was then still largely called developing countries, including by participating for several months in health care in hospitals and remote rural settings (sometimes mobile) as a medical student in northern Nigeria and eastern Nepal. Another influential book was Maurice King's "Medical Care in Developing Countries". I have met Maurice several times, and in 1992 he became BODHI's public health advisor.

Primary health care (PHC) at its simplest, is "the place of first contact with a national health care system". In some countries, especially those that are poor, this means, for the overwhelming majority, health care that is not "tertiary", that is, not hospital-based. Using this definition, PHC need not be sophisticated, and can be delivered not only by people without university training, but without finishing high school. The most famous example of this were China's "barefoot doctors", whose actual benefit is hard to assess, due to the fog of propaganda.

Primary health care horror stories

Care delivered by barefoot doctors and their equivalent, at no or minimal cost to the patient, is obviously cheaper to provide than via medical schools, pharmacists, or properly trained nurses. In many poor settings, it may be better than fee for service alternatives, even if provided by supposed professionals. When I was more involved with the practical aspects of this topic (between 1985 and 1996) I heard horror stories of the financial abuse of patients (mainly in India and Nepal) by health professionals. 


An example I recall is of people with suspected tuberculosis (TB) travelling to a town for a chest X-ray when a sputum examination (at least in skilled hands) is more accurate and useful, and far cheaper. In low income settings (at least then) a chest X-ray, a test whose cost is modest to most readers, could lead to debt (not to mention the travel and foregone income from not working that day).

Also, as is still fairly common, powerful antibiotics were easily available over the counter (i.e. without a doctor's prescription). The risk of such self medication - especially for TB, which requires months of treatment - even if involving rifampicin - is of developing drug-resistant TB, which is an even more expensive and dangerous public health issue. This problem may be less now, due to DOTS - Directly Observed Treatment (short course), which was introduced to reduce this problem. 

In 1994 I spent one harrowing day seeing about 40 Tibetan refugees, as patients, in a camp in South India. Several were on "third line" anti-TB drugs. These third line drugs are expensive, have a high risk of severe side effects, and are not very effective. Patients get put on these drugs generally because the TB bacteria they harbour have evolved resistance to more effective drugs, because the patient did not take them for long enough (many months). The risk is that such resistant bacteria will cause a primary infection in a patient, such as a child, or even a friend or relative who has previously been cured. If it does, that child could be virtually untreatable, and so will the adult.

The possibility that the successes of PHC are over-stated

Ethical and appropriate care by barely trained community and village health workers cannot be guaranteed, and may well be uncommon, despite its supporters, who may "cherry pick" overlooking failures and exaggerating successes. Such care may be adequate for some health problems, many of which get better without treatment or proper diagnosis. Barefoot or village health care workers can also, in some settings, make simple diagnoses, give advice on hygiene, monitor infant and child growth and treat and prevent conditions such as diarrhoea. They might also apply first aid, administer vaccines, and treat a variety of other conditions. 

On the other hand, especially in very low income settings, many people do have significant underlying health conditions, not just TB, but depression, hypertension (very common in some low income settings, perhaps related to undernutrition in childhood) and chronic parasitic infections such as hookworm or schistosomiasis. (Note: hookworm can be easily treated but re-infection is common, where footwear and hygiene are poor, especially from a lack of toilets). 

I met some community health workers, in India, also in 1994. I felt very sorry for them; they had low status, were young, and appeared completely overwhelmed. There are many limitations to the effectiveness of primary health care but its promise to provide an affordable basic underpinning of health for the poor, especially in rural and remote settings, in ways that hospital based care cannot, was alluring, for a while. My personal experience also made me sceptical about some of the claims in David Morley's book. While the village (in Nigeria) he worked seemed a model of success, I was concerned that this depended too much on his nurse, a European with devotion and skills not easily reproduced and sustained in such settings, though, sometimes, religious faith can provide deep and enduring motivation.

But some primary care groups such as Jamkhed have an excellent reputation. With charismatic and dedicated leadership and support, fairly high quality health care can be provided by people without tertiary education. Such people acquire so many skills over time that they effectively are trained at a tertiary level, at least to the equivalent of a good nurse.

Leading to the "sacred moment" at Alma Ata: back to Mahler

Following the immense global trauma of World War II, so soon after the Depression, WHO and the other UN agencies were bathed in hope.

The struggle between social medicine and technical assistance

However, the inception of WHO (1948) was almost immediately followed by the withdrawal of the Soviets and several other socialist countries, from 1949 to 1957. Fee et al, in a useful recent paper (Nov 2016) in the American Journal of Public Health, trace some of the factors leading to this, especially the sacrifice made by the Soviets in World War II (at least 20 million dead, in comparison the US lost 400,000 troops) compounded by limited assistance to the Soviet Union and its allies, such as via the Marshall Plan. Of course, the US and its allies were both horrified and terrified by Communist beliefs, by its contempt for genuine democracy, by the ruthless purges of dissenters by Stalin and others and by the fact that the USSR was also developing nuclear weapons, as the Cold War progressed.

Some time after the USSR re-joined WHO, Dmitry Venediktov, the Soviet delegate to WHO, and a few others, supported by Mahler, called for a shift in focus by WHO, to better reflect the idealistic post WWII framing of health enshrined in the WHO constitution (see in green).
"Health is a state of complete physical, mental and social wellbeing and not merely the absence of disease or infirmity".

"the enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social condition".

"governments have a responsibility for the health of their peoples which can be fulfilled only by the provision of adequate health and social measures ".

Many others in WHO, including Brock Chisholm, the first director-general (a Canadian), hoped that it would still stand by the social medicine principles embodied in its constitution. A key founding member, Andrija Stampar (born in modern Croatia, influenced in medical school in Vienna by Ludwig Teleky’s lectures on social medicine), argued that the WHO should concentrate on 4 principles:

A. social and economic security

B. education
C. nutrition
D. housing.

Taken seriously, a social medicine perspective required questioning the inequality of land ownership in rural areas and the striking inequities, poor housing, misery, and illness in urban areas. However, the United States, WHO's largest funder (at least then) was not interested in this approach and instead promoted the concept of “technical assistance” to the problems of health in what we now call the Global South.

“Technical assistance” conveyed the idea that developing countries were best helped through the transfer of knowledge of science and technology. As many critics have pointed out, this approach bypasses concern with the economic interests and social realities that led to and maintain underdevelopment.
In the 1950s, in its first full decade, WHO had led a massive attempt to eradicate malaria, a clear case of technical assistance. This was inspired by the then recent synthesis of DDT, and the discovery of its almost miraculous insect-killing properties.  It made an enormous difference in India, although most progress there occurred before World War I, which was, actually, the topic of my Master's thesis (at least in the Punjab, which then extended from Delhi right to the Afghan border.)

Fee et al argue that also contributing to the Soviet boycott was a growing conviction on the part of the Soviets and their allies that there were "two dramatically opposing views of public health: that of capitalism and that of communism". This dichotomy persists today.

The election of Mahler: a brief shift towards a social medicine approach by WHO

In 1973, elected WHO director-general, Mahler was able to help channel and shape the political and moral currents of the 1970s. In 1976, early in his directorship, Mahler and WHO accepted a proposal (made by the Soviet Union in 1974) to hold a conference, which was to be called the International Conference on Primary Health Care. In 1977, still led by Mahler, WHO adopted a resolution (WHA30.43) called “Health for All by the Year 2000”.

The conference, which received substantial Soviet support, was held the next year, in Alma Ata, today Almaty, the capital of Kazakhstan, but at that time in the Soviet Union. It was envisaged by Dr. Dmitry Venediktov, then Soviet deputy minister of health, to be on the same scale as the World Population Conference, held in Bucharest in 1974, and attended by more than 1400 people. According to Litsios, Mahler opposed this site, but various alternatives proved unfeasible.

This meeting included the statement that:

“an acceptable level of health for all the people of the world by the year 2000 can be attained.” 
The undermining of Primary Health Care

Soon after the "sacred moment" of Alma-Ata, efforts to weaken Health for All began, (and the broad view of primary health care) weakened, as neoliberalism increased in power. I, with Sharon Friel, also published on this in 2006) - it's also open access, in PLoS Med. We wrote:

"All social movements and scientific disciplines are subject to powerful institutional and natural forces that shape their social, economic, political, and environmental milieu .. like the health promotion movement, WHO is also subject to larger forces. Since Alma Ata, the rhetoric, aspiration, influence, and—arguably—the achievement of WHO has diminished, coincident with a decline in many public goods."

Mario Cuteo, in a 2005 editorial in the Bulletin of WHO also sheds light: "In its more radical version, the complete reform of public health structures and the promotion of major social changes were envisaged, with primary care as the new centre of health systems. In contrast, according to an instrumental interpretation, it was merely an entry point, a temporary relief or an extension of services to underserved areas. The latter interpretation could not avoid being perceived as second-class care, “poor” medicine for poor people."

Cuts to the WHO budget: the counter revolution, led by the US under President Reagan

Brown et al note: "Major donor nations, such as the UK and the US froze contributions to the WHO budget. Then, the Reagan administration decided to pay only 20% of its assessed contributions to all United Nations agencies. In 1979, the Rockefeller Foundation sponsored a small conference included representatives of the World Bank, the US Agency for International Development, the Rockefeller Foundation, and the Ford Foundation, which formulated an alternative “selective primary health care” agenda, which differed sharply from the agenda and spirit of Alma-Ata. Mahler’s principal lieutenant in the battle for Alma-Ata was Ken Newell, a New Zealander, whose edited book Health by the People was influential. 

Newell called these efforts a “counter-revolution.” The World Bank, the main international donor for health development, adopted a neoliberal policy of privatizing health services in the 1980s, further undercutting Alma Ata."

Also excellent and relevant in understanding the decline in the vision of Dr Mahler is the book by David Sanders and David Werner "The Politics of Primary Health Care and Child Survival". See this book review by Claudia Shuftan.

Mahler making enemies

Mahler alienated many people. Another anecdote from Litsios is that, when Director General elect, Mahler supposedly advised a “very powerful president of a developing country,” who had asked Mahler what he could do to develop a health care system (which Mahler told him he did not have) as follows: “I think the first step is to close the medical schools for two years. Then we can discuss what the medical schools were supposed to do, because they really constitute the main focus of resistance to change”. 

Back to the future: world health dominance by corporate-derived foundations 

Technical assistance such as to eradicate malaria was revived, but not by WHO in the 2000s. It is again likely to fail, this time in part because of increasing resistance to insecticides used to impregnate bednets, by mosquitoes, rather than resistance to DDT, the breathrough seen as miraculous in the 1950s. 

Mahler and Family Planning

After retiring from WHO in 1988, Mahler became Director of International Planned Parenthood Federation until 1995. Throughout his career, Mahler emphasised the role of women in promoting health. “Women are the raw material for development”, Worning remembers him saying. The economic and health benefits of spacing children has long been one of my own main pleas. I have written dozens of papers about this, but with little obvious result! (e.g. Reflections on human carrying capacity)

Mahler's final plea

Thirty years after the Alma-Ata Declaration, Mahler told the World Health Assembly in 2008: “To make real progress, we must, therefore, stop seeing the world through our medically tainted glasses. Discoveries on the multifactorial causation of disease have, for a long time, called attention to the association between health problems of great importance to man and social, economic, and other environmental factors.”

Looking forward

Although the Sustainable Development Goals may seem as hopeful and aspirational as Health for All, they have virtually no chance of succeeding. In fact, it is all too plausible that we are headed for a new dark age. The presidency of Donald Trump is but one manifestation of deepening inequality. Ugo Bardi, a member of the Club of Rome, has noted that as cheap energy declines, slavery is returning.  Famines are returning and "regional overload" is obvious in a growing number of locations.

A great awakening is needed. We need new leaders such as Jeremy Corbyn, Bernie Sanders (or maybe Elizabeth Warren) - but not neoliberal Oprah Winfrey. We need more vegetarianism and technological miracles. We need more courage in academia and also in the development movement, who are either blind or self-censoring about high rates of population growth in poor countries. We will need a lot of luck, because leadership such as from Mahler is now very hard to find.

“Regional overload” as an indicator of profound risk: a plea for the public health community to awaken

Comments welcome. First draft of an abstract for a chapter in a forthcoming book to which I have been asked to contribute called: "Medicines for the Anthropocene: Health on a Finite Planet"

Public health is the field of medicine charged with protecting human well-being, via the identification of health risks and the development and implementation of effective strategies to lower such dangers. Public health workers have a long history of promoting new paradigms and tackling vested interests, often with great difficulty and against immense opposition. Their campaigns often take decades to be successful, even at a regional scale.
Today, the greatest threat to global public health is barely visible within public health circles, although, like blind men palpating an elephant, some of its many manifestations are recognized. These identified protuberances have several names. Ecological public health, climate change and health, and even planetary health have arisen, in recent decades, as sub-disciplines of public health. The risk of nuclear war to health has seen the awarding of two Nobel Peace prizes to health-related lobby groups. Tropical medicine has evolved to international health and global health.

Yet, none of these emerging sub-disciplines or fields, as yet, fully integrate the health risks arising from what McMichael called “planetary overload”. Central to this (Malthusian) conceptualization is the risk of large-scale conflict, famine and infectious diseases, acting, increasingly, in combination, in ways that reduce human well-being, as a consequence of linked “eco-social” phenomena. 

Crucially, ecological and environmental contributors to these crises must be recognized not just as living elements of the biosphere, such as crops, coral reefs and forests, but inert resources, particularly of fossil fuels and the rare elements needed to drive the accelerating energy transition. Although the health community is belatedly awakening to the public health harm that climate change constitutes, there is scarcely any recognition, within public health, that the growing scarcity of these inert resources risks the triggering of social consequences with profound adverse health consequences, many of which are already apparent, in examples of what Butler has termed “regional overload”.

There is a growing number of recent examples of this; from Syria to Yemen, South Sudan, north-east Nigeria and Myanmar. However, very little analysis exists, within public health, of the shared causal pathways which underpin these localized public health catastrophes.
There are many reason for this scarcity of analysis. One is the bias, within most public health fields, to problems in high-income settings. Publications on (for example) public health in South Sudan are rare, and data-rich papers are almost non-existent, due to the difficulties of safely obtaining such data. This leads to a reinforcing cycle, a positive feedback loop, where there is little market or appetite for analysis, and where such papers, if submitted are unlikely to be accepted due to their likely deficiencies. 

Another important impediment is of disciplinary boundaries and suspicion of the “academic other”. These factors contribute to the failure of academic institutions and health funders, who are overwhelmingly embedded in a milieu of neoliberal signals and incentives, to recognize the need for a new paradigm to emerge, if humanity is to thrive in this and coming centuries.

2017: in the rear vision mirror, and the world in 2046

In late 2017 I listened to an interview of recent U.S. President Barack Obama, by Britain's Prince Harry. Most of it was quite reasonable, but when Obama claimed that we live in the best time ever I could not agree. 

Famines, Myanmar and Chinese surveillance

As I write, the world is experiencing 5 famines, one of which (Yemen) is shaping as the worst in decades. (The other famines are in South Sudan, NE Nigeria, Somalia, and two regions of the Democratic Republic of the Congo.) Inequality continues to worsen, as do global warming forecasts and climate change reality.

2017 closed with UNICEF reporting how children have been increasingly been used as weapons of war. UNICEF also said parties to conflicts were blatantly disregarding international humanitarian law and children were routinely coming under attack and that rape, forced marriage, abduction and enslavement had become standard tactics in conflicts across Iraq, Syria and Yemen, as well as in Nigeria, South Sudan and Myanmar.

This year also saw the ethnic cleansing of hundreds of thousands of Rohingya from Myanmar, more flouting of the refugee convention by Australia and countless atrocities in many countries in the Middle East and Africa. We have become so conditioned to horror that phenomena such as children or the disabled being forced to act as suicide bombers or entire coral reefs sickening fail to shock us.

Surveillance in China has intensified (a reported 480,000 cameras in Beijing, in 2015) with face recognition technology, other forms of artificial intelligence, and a points system to detect resistance making existence  harrowing in Xinjiang. The self-immolations of Tibetans, which I have long argued are a waste of life (given the indifference and false stereotypes of Tibetans most Chinese hold) continue. Chinese state media has allegedly compared the Dalai Lama to Hitler (n.b. link is in Chinese, I cannot tell if it is valid.) According to a recently released report sourced to the British ambassador to China in 1989, the death toll in the Tiananmen square massacre may have exceeded 10,000 people (see red text). To this day, the mothers of the murdered students are blocked from visiting graves or holding memorials.

Planetary health and human rights

Professionally, 2017 has been challenging, as I continue to seek academic employment, after resigning from a part-time position as a professor at the University of Canberra in July 2016. In late 2017 I resigned from a pro bono writing role with the United Nations Environment Programme. However I continue with many other writing and academic commitments, also pro bono. I have been invited to a workshop for a book on limits to growth and health, in Canada, in April, 2018. To qualify for permission to enter Canada I need a police check, a legacy of my arrest for civil disobedience in 2014, over climate change. I have so far been waiting for a decision for over a month. In December 2017, probably the largest ever civil disobedience protest, in the world, by health professionals, against coal mining occurred, with five arrests. I published an article on this in Croakey.

There have been successes: three invited talks and 4 publications, two in edited books, three chapters in press (all related to limits to growth and health) and one under review for the BMJ, related to novel entities and the so-called nocebo effect. I have posted 29 essays in this blog, which has had over 15,000 views this year. I may be able to enrol for a (second) PhD in 2018, at the University of Sydney, related to "planetary health" and, perhaps, human rights.

As we head to 2018, my main frustration is this. Since 1991, including in most of the previous 50 issues of BODHI Times, I have warned of climate change, neoliberalism, root causes of terrorism and poverty traps, especially in Africa and Asia. A great deal that I (and a few others, including Maurice King and the late Tony McMichael) warned of is now occurring. For example, more than 3,000 would-be migrants drowned in 2017, trying to cross the Mediterranean, many of whom were from the Sahel. The arrival of more than 1.5 million desperate people in Europe, in 2017, has contributed to a right-wing backlash, with a neo-Nazi party now sharing power in Austria, and fears of a return to extremism in Germany, including in its military.

The Gaza Strip has been described by Gideon Levy, a dissident Israeli journalist, as the biggest cage in the world, part of a "never-ending mass experiment on human beings". Levy also describes how the December killing, by Israeli military personnel, of a legless man in a wheelchair "passed almost without mention in Israel. He was one of three demonstrators killed Friday, just another humdrum day."

The world in 2046

BODHI was started by Susan (see photos of her memorial, below) and I in 1989, almost 28 years ago. If we are lucky, there will still be a semblance of civilisation in 2046, in another 28 years. It is likely to be a world of increased inequality, more famines, more surveillance and less freedom. Artificial intelligence and robots will not lead to utopia, but mass social unrest may be reduced by a universal income, at least in more enlightened locations. Weapons systems may be controlled by algorithms; we will be very lucky to avoid nuclear war.

In 1989 this trajectory was broadly foreseeable (see my paper in the 1991 Med J Australia, as an example), but there then seemed time to change it. However, the voices of those trying to head this off have been very faint, and are growing fainter. Neither the dominant media nor dominant academia seems to care; perhaps it is too overwhelming.

Despite all this, it is better to light a candle than curse the darkness. BODHI's partners in India and Bangladesh are lighting such candles. Thank you for reading this far and thank you for your support for BODHI's work.
