The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role.

In response to Trenberth’s argument a second review, by Dr Judith Curry, focuses on the concept of a ‘null hypothesis’ the default position which is taken when research is carried out. Currently the null hypothesis for climate change attribution research is that humans have no influence.

“Humans are changing our climate. There is no doubt whatsoever,” said Trenberth. “Questions remain as to the extent of our collective contribution, but it is clear that the effects are not small and have emerged from the noise of natural variability. So why does the science community continue to do attribution studies and assume that humans have no influence as a null hypothesis?”

To show precedent for his position Trenberth cites the 2007 report by the Intergovernmental Panel on Climate Change which states that global warming is “unequivocal”, and is “very likely” due to human activities.

Trenberth also focused on climate attribution studies which claim the lack of a human component, and suggested that the assumptions distort results in the direction of finding no human influence, resulting in misleading statements about the causes of climate change that can serve to grossly underestimate the role of humans in climate events.

“Scientists must challenge misconceptions in the difference between weather and climate while attribution studies must include a human component,” concluded Trenberth. “The question should no longer be is there a human component, but what is it?”

In a second paper Dr Judith Curry, from the Georgia Institute of Technology, questions this position, but argues that the discussion on the null hypothesis serves to highlight fuzziness surrounding the many hypotheses related to dangerous climate change.

“Regarding attribution studies, rather than trying to reject either hypothesis regardless of which is the null, there should be a debate over the significance of anthropogenic warming relative to forced and unforced natural climate variability,” said Curry.

Curry also suggested that the desire to reverse the null hypothesis may have the goal of seeking to marginalise the climate sceptic movement, a vocal group who have challenged the scientific orthodoxy on climate change.

“The proponents of reversing the null hypothesis should be careful of what they wish for,” concluded Curry. “One consequence may be that the scientific focus, and therefore funding, would also reverse to attempting to disprove dangerous anthropogenic climate change, which has been a position of many sceptics.”

“I doubt Trenberth’s suggestion will find much support in the scientific community,” said Professor Myles Allen from Oxford University, “but Curry’s counter proposal to abandon hypothesis tests is worse. We still have plenty of interesting hypotheses to test: did human influence on climate increase the risk of this event at all? Did it increase it by more than a factor of two?”

Where Did Global Warming Go? (N.Y. Times)

By ELISABETH ROSENTHAL
Published: October 15, 2011

Mark Pernice and Scott Altmann

IN 2008, both the Democratic and Republican candidates for president, Barack Obama and John McCain, warned about man-made global warming and supported legislation to curb emissions. After he was elected, President Obama promised “a new chapter in America’s leadership on climate change,” and arrived cavalry-like at the 2009 United Nations Climate Conference in Copenhagen to broker a global pact.

But two years later, now that nearly every other nation accepts climate change as a pressing problem, America has turned agnostic on the issue.

In the crowded Republican presidential field, most seem to agree with Gov. Rick Perry of Texas that “the science is not settled” on man-made global warming, as he said in a debate last month. Alone among Republicans onstage that night, Jon M. Huntsman Jr. said that he trusted scientists’ view that the problem was real. At the moment, he has the backing of about 2 percent of likely Republican voters.

Though the evidence of climate change has, if anything, solidified, Mr. Obama now talks about “green jobs” mostly as a strategy for improving the economy, not the planet. He did not mention climate in his last State of the Union address. Meanwhile, the administration is fighting to exempt United States airlines from Europe’s new plan to charge them for CO2 emissions when they land on the continent. It also seems poised to approve a nearly 2,000-mile-long pipeline, from Canada down through the United States, that will carry a kind of oil. Extracting it will put relatively high levels of emissions into the atmosphere.

“In Washington, ‘climate change’ has become a lightning rod, it’s a four-letter word,” said Andrew J. Hoffman, director of the University of Michigan’s Erb Institute for Sustainable Development.

Across the nation, too, belief in man-made global warming, and passion about doing something to arrest climate change, is not what it was five years or so ago, when Al Gore’s movie had buzz and Elizabeth Kolbert’s book about climate change, “Field Notes From a Catastrophe,” was a best seller. The number of Americans who believe the earth is warming dropped to 59 percent last year from 79 percent in 2006, according to polling by the Pew Research Group. When the British polling firm Ipsos Mori asked Americans this past summer to list their three most pressing environmental worries, “global warming/climate change” garnered only 27 percent, behind even “overpopulation.”

This fading of global warming from the political agenda is a mostly American phenomenon. True, public enthusiasm for legislation to tackle climate change has flagged somewhat throughout the developed world since the recession of 2008. Nonetheless, in many other countries, legislation to control emissions has rolled out apace. Just last Wednesday, Australia’s House of Representatives passed a carbon tax, which is expected to easily clear the country’s Senate. Europe’s six-year-old carbon emissions trading system continues its yearly expansion. In 2010, India passed a carbon tax on coal. Even China’s newest five-year plan contains a limited pilot cap-and-trade system, under which polluters pay for excess pollution.

The United States is the “one significant outlier” on responding to climate change, according to a recent global research report produced by HSBC, the London-based bank. John Ashton, Britain’s special representative for climate change, said in an interview that “in the U.K., in Europe, in most places I travel to” — but not in the United States — “the starting point for conversation is that this is real, there are clear and present dangers, so let’s get a move on and respond.” After watching the Republican candidates express skepticism about global warming in early September, former President Bill Clinton put it more bluntly, “I mean, it makes us — we look like a joke, right?”

Americans — who produce twice the emissions per capita that Europeans do — are in many ways wired to be holdouts. We prefer bigger cars and bigger homes. We value personal freedom, are suspicious of scientists, and tend to distrust the kind of sweeping government intervention required to confront rising greenhouse gas emissions.

“Climate change presents numerous ideological challenges to our culture and our beliefs,” Professor Hoffman of the Erb Institute says. “People say, ‘Wait a second, this is really going to affect how we live!’ ”

There are, of course, other factors that hardened resistance: America’s powerful fossil-fuel industry, whose profits are bound to be affected by any greater control of carbon emissions; a cold American winter in 2010 that made global warming seem less imminent; and a deep recession that made taxes on energy harder to talk about, and job creation a more pressing issue than the environment — as can be seen in the debate over the pipeline from Canada.

But it is also true that Europe has endured a deep recession and has had mild winters. What’s more, some of the loudest climate deniers are English. Yet the European Union is largely on target to meet its goal of reducing emissions by at least 20 percent over 1990 levels by 2020.

Connie Hedegaard, the European Union’s commissioner on climate action, told me recently: “Look, it was not a piece of cake here either.”

In fact, many countries in Europe have come to see combating climate change and the move to a “greener” economy as about “opportunities rather than costs,” Mr. Ashton said. In Britain, the low-carbon manufacturing sector has been one of the few to grow through the economic slump.

“One thing I’ve been pleasantly surprised about in the E.U. is that despite the economic and financial crisis, the momentum on climate change has more or less continued,” Mr. Ashton said.

And Conservatives, rather than posing an obstacle, are directing aggressive climate policies in much of the world. Before becoming the European Union’s commissioner for climate action, Ms. Hedegaard was a well-known Conservative politician in her native Denmark. In Britain, where a 2008 law required deep cuts in emissions, a coalition Conservative government is now championing a Green Deal.

In the United States, the right wing of the Republican Party has managed to turn skepticism about man-made global warming into a requirement for electability, forming an unlikely triad with antiabortion and gun-rights beliefs. In findings from a Pew poll this spring, 75 percent of staunch conservatives, 63 percent of libertarians and 55 percent of Main Street Republicans said there was no solid evidence of global warming.

“This has become a partisan political issue here in a way it has not elsewhere,” said Andrew Kohut, president of the Pew Research Center. “We are seeing doubts in the U.S. largely because the issue has become a partisan one, with Democrats” — 75 percent of whom say they believe there is strong evidence of climate change — “seeing one thing and Republicans another.”

Europeans understand the challenges in the United States, though they sound increasingly impatient. “We are very much aware of the political situation in the United States and we don’t say ‘do this,’ when we know it can’t get through Congress,” said Ms. Hedegaard, when she was in New York for the United Nations General Assembly last month. But she added:

“O.K. if you can’t commit today, when can you? When are you willing to join in? Australia is making a cap-and-trade system. South Korea is introducing one. New Zealand and the E.U. have it already. So when is the time? That’s the question for the U.S.”

MEANWHILE, in the developing world, emerging economies like India and China are now pursuing aggressive climate policies. “Two years ago the assumption was that the developed world would have to lead, but now China, India and Brazil have jumped in with enthusiasm, and are moving ahead,” said Nick Robins of HSBC Global Research.

Buffeted by two years of treacherous weather that they are less able to handle than richer nations — from floods in India to water shortages in China — developing countries are feeling vulnerable. Scientists agree that extreme weather events will be more severe and frequent on a warming planet, and insurance companies have already documented an increase.

So perhaps it is no surprise that regard for climate change as “a very serious problem” has risen significantly in many developing nations over the past two years. A 2010 Pew survey showed that more than 70 percent of people in China, India and South Korea were willing to pay more for energy in order to address climate change. The number in the United States was 38 percent. China’s 12th five-year plan, for 2011-2015, directs intensive investment to low carbon industries. In contrast, in the United States, there is “no prospect of moving ahead” at a national legislative level, Mr. Robins said, although some state governments are addressing the issue.

In private, scientific advisers to Mr. Obama say he and his administration remain committed to confronting climate change and global warming. But Robert E. O’Connor, program director for decision, risk and management sciences at the National Science Foundation in Washington, said a bolder leader would emphasize real risks that, apparently, now feel distant to many Americans. “If it’s such an important issue, why isn’t he talking about it?”

Governo apresenta oficialmente oito propostas para a Rio+20 (Jornal da Ciência)

JC e-mail 4376, de 01 de Novembro de 2011.

O governo apresenta nesta terça-feira (1º) a versão oficial do documento com oito propostas para a Conferência das Nações Unidas sobre o Desenvolvimento Sustentável, conhecida como Rio+20, a ser realizada no Rio de Janeiro de 28 de maio a 6 de junho de 2012. O documento foi apresentado hoje pela ministra do Meio Ambiente, Izabella Teixeira e pelo Itamaraty, em coletiva de imprensa, em Brasília.

A primeira proposta é a criação de um programa de proteção socioambiental global, cujo objetivo é assegurar garantia de renda para superar a pobreza extrema no mundo e promover ações estruturantes que garantam qualidade ambiental, segurança alimentar, moradia adequada e acesso à água limpa para todos.

A ideia desse programa, conforme consta do documento, é fazer com que “toda estrutura multilateral opere” para facilitar o acesso a tecnologias, recursos financeiros, infraestrutura e capacitação, a fim de que todas as pessoas tenham a quantidade e qualidade mínima de alimento, água e ambiente saudável.

Pela proposta brasileira, esse programa teria como foco uma estratégia de garantia de renda adequada às condições de cada país, diante de um momento de crise internacional em que se mobilizam vastos recursos globais para a recuperação do sistema financeiro. “O programa seria uma aposta no componente social, importante na solução brasileira para o enfrentamento da crise”, destaca o documento. “Essa é uma plataforma de diálogo global que poderia ser um passo crucial rumo ao desenvolvimento sustentável, com potencial para reforçar o papel virtuoso do multilateralismo”, complementa.

Na segunda proposta, o governo sugere a implementação de “objetivos de desenvolvimento sustentável”, adotando um programa de economia verde inclusiva, em lugar “de negociações complexas que busquem o estabelecimento de metas restritivas vinculantes”. Dentre outros, esses objetivos poderiam estar associados a erradicação da pobreza extrema; a segurança alimentar e nutricional; acesso a empregos adequados (socialmente justos e ambientalmente corretos); acesso a fontes adequadas de energia; a microempreendedorismo e microcrédito; a inovação para a sustentabilidade; acesso a fontes adequadas de recursos hídricos; e adequação da pegada ecológica à capacidade de regeneração do planeta.

Compras públicas sustentáveis – Na terceira proposta, o Brasil sugere um pacto global para produção e consumo sustentáveis. Ou seja, um conjunto de iniciativas para promover mudanças nos padrões de produção e consumo em diversos setores. Dessa forma, poderiam ser adotadas, com caráter prioritário, iniciativas que ofereçam suporte político a compras públicas sustentáveis, já que essas representam parte significativa da economia internacional, de cerca de 15% do Produto Interno Bruto (PIB) mundial; a classificações de consumo e eficiência energética; e financiamento de estudos e pesquisas para o desenvolvimento sustentável (com o objetivo de qualificar recursos humanos de alto nível e apoiar projetos científicos, tecnológicos e inovadores).

A quarta proposta sugere estabelecer repositório de iniciativas para dinamizar os mecanismos nacionais e de cooperação internacional, inclusive a utilização de recursos dos organismos multilaterais. Já a quinta sugestão propõe a criação de protocolo internacional para a sustentabilidade do setor financeiro.

Na sexta proposta o governo sugere novos indicadores para mensuração do desenvolvimento. Hoje os mais importantes são o Índice de Desenvolvimento Humano (IDH) e o Produto Interno Bruto (PIB) que, como medida de desenvolvimento sustentável, “são claramente limitadas”, por não integrarem a grande diversidade de aspectos sociais e ambientais aos valores econômicos, o que induz, segundo o documento, a percepções errôneas do grau de desenvolvimento e de progresso dos países.

Na sétima proposta o governo sugere a implementação de um “pacto pela economia verde inclusiva. A ideia é estimular a divulgação de relatórios e de índices de sustentabilidade por empresas estatais, bancos de fomento, patrocinadoras de entidades de previdência privada, empresas de capital aberto e empresas de grande porte. Ou seja, além dos aspectos econômico-financeiros, essas instituições incluam nas divulgações, obrigatoriamente, e de acordo com padrões internacionalmente aceitos e comparáveis, informações sobre suas atuações em termos sociais, ambientais e de governança corporativa.

Por sua vez, a oitava proposta é ligada a “estrutura institucional do desenvolvimento sustentável. Essa aborda vários tópicos, dentre os quais a adoção de mecanismo de coordenação institucional para o desenvolvimento sustentável”; reforma do Conselho Econômico e Social das Nações Unidas (ECOSOC), transformando-o em Conselho de Desenvolvimento Sustentável das Nações Unidas; aperfeiçoamento da governança ambiental internacional; o lançamento de processo negociador para uma convenção global sobre acesso à informação, participação pública na tomada de decisões e acesso à justiça em temas ambientais; e a governança da água.

The world at seven billion (BBC)

27 October 2011 Last updated at 23:08 GMT

As the world population reaches seven billion people, the BBC’s Mike Gallagher asks whether efforts to control population have been, as some critics claim, a form of authoritarian control over the world’s poorest citizens.

The temperature is some 30C. The humidity stifling, the noise unbearable. In a yard between two enormous tea-drying sheds, a number of dark-skinned women patiently sit, each accompanied by an unwieldy looking cloth sack. They are clad in colourful saris, but look tired and shabby. This is hardly surprising – they have spent most of the day in nearby plantation fields, picking tea that will net them around two cents a kilo – barely enough to feed their large families.

Vivek Baid thinks he knows how to help them. He runs the Mission for Population Control, a project in eastern India which aims to bring down high birth rates by encouraging local women to get sterilised after their second child.

As the world reaches an estimated seven billion people, people like Vivek say efforts to bring down the world’s population must continue if life on Earth is to be sustainable, and if poverty and even mass starvation are to be avoided.

There is no doubting their good intentions. Vivek, for instance, has spent his own money on the project, and is passionate about creating a brighter future for India.

But critics allege that campaigners like Vivek – a successful and wealthy male businessman – have tended to live very different lives from those they seek to help, who are mainly poor women.

These critics argue that rich people have imposed population control on the poor for decades. And, they say, such coercive attempts to control the world’s population often backfired and were sometimes harmful.

Population scare

Most historians of modern population control trace its roots back to the Reverend Thomas Malthus, an English clergyman born in the 18th Century who believed that humans would always reproduce faster than Earth’s capacity to feed them.

Giving succour to the resulting desperate masses would only imperil everyone else, he said. So the brutal reality was that it was better to let them starve.

‘Plenty is changed into scarcity’

Thomas Malthus

From Thomas Malthus’ Essay on Population, 1803 edition:

A man who is born into a world already possessed – if he cannot get subsistence from his parents on whom he has a just demand, and if the society do not want his labour, has no claim of right to the smallest portion of food.

At nature’s mighty feast there is no vacant cover for him. She tells him to be gone, and will quickly execute her own orders, if he does not work upon the compassion of some of her guests. If these guests get up and make room for him, other intruders immediately appear demanding the same favour. The plenty that before reigned is changed into scarcity; and the happiness of the guests is destroyed by the spectacle of misery and dependence in every part of the hall.

Rapid agricultural advances in the 19th Century proved his main premise wrong, because food production generally more than kept pace with the growing population.

But the idea that the rich are threatened by the desperately poor has cast a long shadow into the 20th Century.

From the 1960s, the World Bank, the UN and a host of independent American philanthropic foundations, such as the Ford and Rockefeller foundations, began to focus on what they saw as the problem of burgeoning Third World numbers.

The believed that overpopulation was the primary cause of environmental degradation, economic underdevelopment and political instability.

Massive populations in the Third World were seen as presenting a threat to Western capitalism and access to resources, says Professor Betsy Hartmann of Hampshire College, Massachusetts, in the US.

“The view of the south is very much put in this Malthusian framework. It becomes just this powerful ideology,” she says.

In 1966, President Lyndon Johnson warned that the US might be overwhelmed by desperate masses, and he made US foreign aid dependent on countries adopting family planning programmes.

Other wealthy countries such as Japan, Sweden and the UK also began to devote large amounts of money to reducing Third World birth rates.

‘Unmet need’

What virtually everyone agreed was that there was a massive demand for birth control among the world’s poorest people, and that if they could get their hands on reliable contraceptives, runaway population growth might be stopped.

But with the benefit of hindsight, some argue that this so-called unmet need theory put disproportionate emphasis on birth control and ignored other serious needs.

“It was a top-down solution,” says Mohan Rao, a doctor and public health expert at Delhi’s Jawaharlal Nehru University.

“There was an unmet need for contraceptive services, of course. But there was also an unmet need for health services and all kinds of other services which did not get attention. The focus became contraception.”

Had the demographic experts worked at the grass-roots instead of imposing solutions from above, suggests Adrienne Germain, formerly of the Ford Foundation and then the International Women’s Health Coalition, they might have achieved a better picture of the dilemmas facing women in poor, rural communities.

“Not to have a full set of health services meant women were either unable to use family planning, or unwilling to – because they could still expect half their kids to die by the age of five,” she says.

India’s sterilisation ‘madness’

File photograph of Sanjay and Indira Gandhi in 1980

Indira Gandhi and her son Sanjay (above) presided over a mass sterilisation campaign. From the mid-1970s, Indian officials were set sterilisation quotas, and sought to ingratiate themselves with superiors by exceeding them. Stories abounded of men being accosted in the street and taken away for the operation. The head of the World Bank, Robert McNamara, congratulated the Indian government on “moving effectively” to deal with high birth rates. Funding was increased, and the sterilising went on.

In Delhi, some 700,000 slum dwellers were forcibly evicted, and given replacement housing plots far from the city centre, frequently on condition that they were either sterilised or produced someone else for the operation. In poorer agricultural areas, whole villages were rounded up for sterilisation. When residents of one village protested, an official is said to have threatened air strikes in retaliation.

“There was a certain madness,” recalls Nina Puri of the Family Planning Association of India. “All rationality was lost.”

Us and them

In 1968, the American biologist Paul Ehrlich caused a stir with his bestselling book, The Population Bomb, which suggested that it was already too late to save some countries from the dire effects of overpopulation, which would result in ecological disaster and the deaths of hundreds of millions of people in the 1970s.

Instead, governments should concentrate on drastically reducing population growth. He said financial assistance should be given only to those nations with a realistic chance of bringing birth rates down. Compulsory measures were not to be ruled out.

Western experts and local elites in the developing world soon imposed targets for reductions in family size, and used military analogies to drive home the urgency, says Matthew Connelly, a historian of population control at Columbia University in New York.

“They spoke of a war on population growth, fought with contraceptive weapons,” he says. “The war would entail sacrifices, and collateral damage.”

Such language betrayed a lack of empathy with their subjects, says Ms Germain: “People didn’t talk about people. They talked of acceptors and users of family planning.”

Emergency measures

Critics of population control had their say at the first ever UN population conference in 1974.

Karan Singh, India’s health minister at the time, declared that “development is the best contraceptive”.

But just a year later, Mr Singh’s government presided over one of the most notorious episodes in the history of population control.

In June 1975, the Indian premier, Indira Gandhi, declared a state of emergency after accusations of corruption threatened her government. Her son Sanjay used the measure to introduce radical population control measures targeted at the poor.

The Indian emergency lasted less than two years, but in 1975 alone, some eight million Indians – mainly poor men – were sterilised.

Yet, for all the official programmes and coercion, many poor women kept on having babies.

And where they did not, it arguably had less to do with coercive population control than with development, just as Karan Singh had argued in 1974, says historian Matt Connelly.

For example, in India, a disparity in birth rates could already be observed between the impoverished northern states and more developed southern regions like Kerala, where women were more likely to be literate and educated, and their offspring more likely to be healthy.

Women there realised that they could have fewer births and still expect to see their children survive into adulthood.

China: ‘We will not allow your baby to live’

Steven Mosher was a Stanford University anthropologist working in rural China who witnessed some of the early, disturbing moments of Beijing’s One Child Policy.

“I remember very well the evening of 8 March, 1980. The local Communist Party official in charge of my village came over waving a government document. He said: ‘The Party has decided to impose a cap of 1% on population growth this year.’ He said: ‘We’re going to decide who’s going to be allowed to continue their pregnancy and who’s going to be forced to terminate their pregnancy.’ And that’s exactly what they did.”

“These were women in the late second and third trimester of pregnancy. There were several women just days away from giving birth. And in my hearing, a party official said: ‘Do not think that you can simply wait until you go into labour and give birth, because we will not allow your baby to live. You will go home alone’.”

Total control

By now, this phenomenon could be observed in another country too – one that would nevertheless go on to impose the most draconian population control of all.

The One Child Policy is credited with preventing some 400 million births in China, and remains in place to this day. In 1983 alone, more than 16 million women and four million men were sterilised, and 14 million women received abortions.

Assessed by numbers alone, it is said to be by far the most successful population control initiative. Yet it remains deeply controversial, not only because of the human suffering it has caused.

A few years after its inception, the policy was relaxed slightly to allow rural couples two children if their first was not a boy. Boy children are prized, especially in the countryside where they provide labour and care for parents in old age.

But modern technology allows parents to discover the sex of the foetus, and many choose to abort if they are carrying a girl. In some regions, there is now a serious imbalance between men and women.

Moreover, since Chinese fertility was already in decline at the time the policy was implemented, some argue that it bears less responsibility for China’s falling birth rate than its supporters claim.

“I don’t think they needed to bring it down further,” says Indian demographer AR Nanda. “It would have happened at its own slow pace in another 10 years.”

Backlash

In the early 1980s, objections to the population control movement began to grow, especially in the United States.

In Washington, the new Reagan administration removed financial support for any programmes that involved abortion or sterilisation.

“If you give women the tools they need – education, employment, contraception, safe abortion – then they will make the choices that benefit society”

Adrienne Germain

The broad alliance to stem birth rates was beginning to dissolve and the debate become more polarised along political lines.

While some on the political right had moral objections to population control, some on the left saw it as neo-colonialism.

Faith groups condemned it as a Western attack on religious values, but women’s groups feared changes would mean poor women would be even less well-served.

By the time of a major UN conference on population and development in Cairo in 1994, women’s groups were ready to strike a blow for women’s rights, and they won.

The conference adopted a 20-year plan of action, known as the Cairo consensus, which called on countries to recognise that ordinary women’s needs – rather than demographers’ plans – should be at the heart of population strategies.

After Cairo

Today’s record-breaking global population hides a marked long-term trend towards lower birth rates, as urbanisation, better health care, education and access to family planning all affect women’s choices.

With the exception of sub-Saharan Africa and some of the poorest parts of India, we are now having fewer children than we once did – in some cases, failing even to replace ourselves in the next generation. And although total numbers are set to rise still further, the peak is now in sight.

Chinese poster from the 1960s of mother and baby, captioned: Practicing birth control is beneficial for the protection of the health of mother and childChina promoted birth control before implementing its one-child policy

Assuming that this trend continues, total numbers will one day level off, and even fall. As a result, some believe the sense of urgency that once surrounded population control has subsided.

The term population control itself has fallen out of fashion, as it was deemed to have authoritarian connotations. Post-Cairo, the talk is of women’s rights and reproductive rights, meaning the right to a free choice over whether or not to have children.

According to Adrienne Germain, that is the main lesson we should learn from the past 50 years.

“I have a profound conviction that if you give women the tools they need – education, employment, contraception, safe abortion – then they will make the choices that benefit society,” she says.

“If you don’t, then you’ll just be in an endless cycle of trying to exert control over fertility – to bring it up, to bring it down, to keep it stable. And it never comes out well. Never.”

Nevertheless, there remain to this day schemes to sterilise the less well-off, often in return for financial incentives. In effect, say critics, this amounts to coercion, since the very poor find it hard to reject cash.

“The people proposing this argue ‘Don’t worry, everything’ s fine now we have voluntary programmes on the Cairo model’,” says Betsy Hartmann.

“But what they don’t understand is the profound difference in power between rich and poor. The people who provide many services in poor areas are already prejudiced against the people they serve.”

Work in progress

For Mohan Rao, it is an example of how even the Cairo consensus fails to take account of the developing world.

“Cairo had some good things,” he says. “However Cairo was driven largely by First World feminist agendas. Reproductive rights are all very well, but [there needs to be] a whole lot of other kinds of enabling rights before women can access reproductive rights. You need rights to food, employment, water, justice and fair wages. Without all these you cannot have reproductive rights.”

Perhaps, then, the humanitarian ideals of Cairo are still a work in progress.

Meanwhile, Paul Ehrlich has also amended his view of the issue.

If he were to write his book today, “I wouldn’t focus on the poverty-stricken masses”, he told the BBC.

“I would focus on there being too many rich people. It’s crystal clear that we can’t support seven billion people in the style of the wealthier Americans.”

Brasil já pesquisa efeitos da mudança do clima (Valor Econômico)

JC e-mail 4373, de 27 de Outubro de 2011.

As pesquisas em mudança climática no Brasil começam a mudar de rumo. Se há alguns anos o foco estava nos esforços de redução das emissões dos gases-estufa, agora miram a adaptação ao fenômeno.

“Sabemos que nos próximos cinco ou dez anos não há perspectiva para que seja firmado internacionalmente um acordo de redução nas emissões de gases-estufa de grandes proporções, com cortes entre 70% a 80%”, diz o físico Paulo Artaxo, da USP, um estudioso da Amazônia. “Esse panorama é cada vez mais longínquo. Portanto é fundamental que se estudem estratégias de adaptação.”

Em outras palavras, as pesquisas devem se voltar para os efeitos da mudança do clima nos ecossistemas, em ambientes urbanos, em contextos sociais. “Não é uma questão de dinheiro, mas de direcionamento dos estudos”, diz Artaxo, membro do conselho diretor do Painel Brasileiro de Mudança Climática, órgão científico ligado aos ministérios da Ciência e Tecnologia e Ambiente. “O País precisa se preparar mais adequadamente para a mudança climática.”

“É preciso pesquisar mais, por exemplo, as alterações no ciclo hidrológico”, cita Reynaldo Victoria, coordenador do Programa Fapesp de Pesquisa sobre Mudanças Climáticas Globais. “Saber onde vai chover mais e onde vai chover menos”, explica. É um dos braços da pesquisa de Artaxo na Amazônia. “Porque não se quer construir uma hidrelétrica onde choverá muito menos nas próximas décadas”, ilustra o físico.

O programa de mudança climática da Fapesp já conta com investimentos de US$ 30 milhões em projetos na área. É um dos braços mais novos da fundação, mas já está ganhando musculatura. Tem 21 projetos em andamento, 14 contratos novos, dois outros em parceria com instituições estrangeiras, como o britânico Natural Environment Research Council (Nerc) ou a francesa Agence Nationale de la Recherche (ANR). Em dez anos, a previsão é de investimentos de mais de R$ 100 milhões.

As pesquisas começam a se voltar para campos pouco estudados. “Vamos analisar questões críticas para o Brasil”, diz Artaxo. Ele cita, por exemplo, o ciclo de carbono na Amazônia – algo muito mais complexo do que estudar a fotossíntese e a respiração das plantas.

Victoria, que também é professor do Centro de Energia Nuclear Aplicada à Agricultura (Cena-USP), diz que a intenção do programa é mirar campos novos, como entender qual o papel do Atlântico Sul no clima da região Sul do Brasil e Norte da Argentina. Outro exemplo é obter registros históricos na área de paleoclima.

Os impactos na área de saúde também serão mais estudados. Já se sabe que a mudança do clima faz com que doenças que não existiam em determinado lugar, passem a ocorrer. A dengue, por exemplo, encontra ambiente propício em regiões mais quentes. Entre as novas pesquisas de doenças emergentes há o estudo de um tipo de leishmaniose, comum na Bolívia e no Peru, que não existia no Brasil e agora ameaça surgir no Acre. Provocada por um mosquito, a doença causa uma infecção cutânea e pode ser mortal.

Os pesquisadores falaram sobre seus projetos durante a Fapesp Week, evento que faz parte da comemoração pelos 50 anos da Fundação de Amparo à Pesquisa do Estado de São Paulo e terminou ontem, em Washington.

Terra, que Tempo é Esse? (PUC)

Por Gabriela Caesar – Do Portal, 28/10/2011. Fotos: Eduardo de Holanda.

Embora a “soberania nacional e o mercado criem cenário conflitoso”, a população está consciente de que o estilo de vida precisa mudar, acredita o antropólogo Roberto da Matta. Já a jornalista Sônia Bridi pondera que “não adianta discutir ou culpar quem começou”, mas trocar o modelo de produção. Reunidos na PUC-Rio para o debate “Terra, que tempo é esse?” (assista às partes 1 e 2 abaixo), nesta segunda-feira (24), com mediação do professor Paulo Ferracioli, do Departamento de Economia, eles reforçaram a importância de um desenvolvimento mais alinhado às demandas ambientais.

O secretário estadual do Ambiente, Carlos Minc (PT-RJ), acrescentou que a negociação com grandes empresas, como a Companhia Siderúrgica Nacional (CSN), deve incluir o acompanhamento de tecnologias que possam não só diminuir as agressões ambientais, mas também resguardar a saúde dos trabalhadores. Ainda em relação a tecnologias “ecologicamente corretas”, Sônia Bridi afirmou que o estado do Rio “erra ao se decidir por ônibus, em vez de veículo leve sobre trilho”.

Diante dos aproximadamente cem estudantes que acompanhavam o debate no auditório do RDC, Roberto da Matta destacou que a mudança para um estilo de vida mais saudável e comprometido com o ambiente revela-se igualmente importante para combater outro problema, segundo ele, agravado pela globalização: a obesidade mórbida, que dá origem ao neologismo “globesidade”. Para diminuir o avanço da doença, que aumentou em um terço na China, o antropólogo é categórico ao propor um padrão social menos consumista.

Usina de contrastes e um dos principais lubrificantes do consumo mundial, a China encara o desafio de reduzir as faturas ambientais – alvo recorrente de críticas em foruns internacionais – e de saúde. Para Sônia Bridi, a locomotiva da economia global investe no longo prazo:

– Até 2020, a China terá 20 mil quilômetros de trem bala. Eles estão preocupados com isso, porque a qualidade da saúde deles está piorando muito.

O trilho do desenvolvimento responsável não passa necessariemente por grandes investimentos. O diretor do Núcleo Interdisciplinar do Meio Ambiente (Nima), Luiz Felipe Guanaes, lembrou que iniciativas como a coleta seletiva, implantada em junho deste ano no campus da PUC-Rio, também aproximam o cidadão de um maior compromisso ambiental e social. Outra oportunidade de a “comunidade se engajar na causa”, lembrou ele, será o encontro de pesquisadores e especialistas na universidade em 2012, para a Rio+20, em parceria com a ONU.

Sônia também contou bastidores da série de reportagem “Terra, que país é esse?” – que mostrou os avanços do aquecimento global e nomeou o debate. No Peru, ela e o repórter cinematográfico Paulo Zero notaram o impacto no cotidiano, até em rituais.

– Num determinado dia, próximo à festa do Corpus Christi, confrarias do país inteiro sobem certa montanha e colhem blocos de gelo. Tiveram de mudar o ritual, que vem do tempo dos incas, incorporado pelo cristianismo. Eles pararam de tirar gelo.

Paulo Zero admite que a produção jornalística, atrelada ao cumprimento de prazos “curtos”, dificulta o tratamento do assunto. Outra barreira, diz Paulo, pode ser a logística. Para a reportagem na Groelândia, por exemplo, ele e Sônia navegaram por seis horas até chegar à ilha. Se o trajeto atrapalhou, a sorte foi uma aliada.

– Chegamos à geleira e, em cinco minutos, caiu um grande bloco de gelo. Ficamos mais três horas lá e não caiu mais nenhum pedaço de gelo. Ou seja, estávamos na hora certa e no lugar certo – contou o cinegrafista.

Limite próximo (Fapesp)

Amazônia está muito próxima de um ponto de não retorno para sua sobrevivência, diz Thomas Lovejoy, da George Mason University, no simpósio internacional FAPESP Week (foto: JVInfante Photography/Wilson Center)

27/10/2011

Agência FAPESP – A Amazônia está muito próxima de um ponto de não retorno para sua sobrevivência, devido a uma combinação de fatores que incluem aquecimento global, desflorestamento e queimadas que minam seu sistema hidrogeológico.

A advertência foi feita por Thomas Lovejoy, atualmente professor da George Mason University, no Estado de Virgínia, EUA, no primeiro dia do simpósio internacional FAPESP Week, em Washington, nesta segunda-feira.

O biólogo Lovejoy, um dos mais importantes especialistas em Amazônia do mundo, começou a trabalhar na floresta brasileira em 1965, “apenas três anos depois da fundação da FAPESP”, lembrou.

Apesar de muita coisa positiva ter acontecido nestes 47 anos (“quando pisei pela primeira vez em Belém, só havia uma floresta nacional e uma área indígena demarcada e quase nenhum cientista brasileiro se interessava em estudar a Amazônia; hoje esse situação está totalmente invertida”), também apareceram no período diversos fatores de preocupação.

Lovejoy acredita que restam cinco anos para inverter as tendências em tempo de evitar problemas de maior gravidade. O aquecimento da temperatura média do planeta já está na casa de 0,8 grau centígrado. Ele acredita que o limite aceitável é de 2 graus centígrados e que ele pode ser alcançado até 2016 se nada for feito para efetivamente reduzi-lo.

O objetivo fixado nas mais recentes reuniões sobre o clima em Cancun e Copenhague de limitar o aumento médio da temperatura média global em 2 graus centígrados pode ser insuficiente, na opinião de Lovejoy, devido a essa conjugação de elementos.

De forma similar, Lovejoy crê que 20% de desflorestamento em relação ao tamanho original da Amazônia é o máximo que ela consegue suportar e o atual índice já é de 17% (em 1965, a taxa era de 3%).

A boa notícia, diz o biólogo, é que há bastante terra abandonada, sem nenhuma perspectiva de utilização econômica na Amazônia e que pode ser de alguma forma reflorestada, o que poderia proporcionar certa margem de segurança.

Em sua palestra, Lovejoy saudou vários cientistas brasileiros como exemplares em excelência em suas pesquisas. Entre outros, Eneas Salati, Carlos Nobre e Carlos Joly.

The Post-Normal Seduction of Climate Science (Forbes)

William Pentland10/14/2011 @ 12:22AM |2,770 views

In early 2002, former U.S. Defense Secretary Donald Rumsfeld explained why the lack of evidence linking Saddam Hussein with terrorist groups did not mean there was no connection during a televised press conference.

“[T]here are known ‘knowns’ – there are things we know we know,” said Rumsfeld. “We also know there are known ‘unknowns’ – that is to say we know there are some things we do not know. But there are also unknown ‘unknowns’ – the ones we don’t know we don’t know . . . it is the latter category that tend to be the difficult ones.”

Rumsfeld turned out to be wrong about Hussein, but what if he had been talking about global warming?  Well, he probably would have been on to something there.  Unknowns of any ilk are a real pickle in climate science.

Indeed, uncertainty in climate science has induced a state of severe political paralysis. The trouble is that nobody really knows why. A rash of recent surveys and studies have exonerated most of the usual suspects – scientific illiteracy, industry distortions, skewed media coverage.

Now, the climate-science community is scrambling to crack the code on the “uncertainty” conundrum. Exhibit A: the October 2011 issue of the journal Climatic Change, the closest thing in climate science to gospel truth, which is devoted entirely to the subject of uncertainty.

While I have yet to digest all of the dozen or so essays, I suspect they are only the opening salvo in what is will soon become a robust debate about the significance of uncertainty in climate-change science. The first item up on the chopping block is called post-normal science (PNS).

PNS is a model of the scientific process pioneered by Jerome Ravetz and Silvio Funtowicz, which describes the peculiar challenges science encounters where “facts are uncertain, values in dispute, stakes high and decisions urgent.” Unlike “normal” science in the sense described by the philosopher of science Thomas Kuhn, post-normal science commonly crosses disciplinary lines and involves new methods, instruments and experimental systems.

Judith Curry, a professor at Georgia Tech, weighs the wisdom of taking the plunge on PNS in an excellent piece called “Reasoning about climate uncertainty.” Drawing on the work of Dutch wunderkind, Jeroen van der Sluijs, Curry calls on the Intergovernmental Panel on Climate Change to stop marginalizing uncertainty and get real about bias in the consensus building process. Curry writes:

The consensus approach being used by the IPCC has failed to produce a thorough portrayal of the complexities of the problem and the associated uncertainties in our understanding . . . Better characterization of uncertainty and ignorance and a more realistic portrayal of confidence levels could go a long way towards reducing the “noise” and animosity portrayed in the media that fuels the public distrust of climate science and acts to stymie the policy process.

PNS is especially seductive in the context of uncertainty. Not surprisingly, Curry suggests that instituting PNS-like strategies at the IPCC “could go a long way towards reducing the ‘noise’ and animosity” surrounding climate-change science.

While I personally believe PNS is persuasive, the PNS model provokes something closer to revulsion in many people. Last year, members of the U.S. House of Representatives filed a petition challenging the U.S. Environmental Protection Agency‘s Greenhouse Gas Endangerment seemed less sanguine about post-normal science:

. . . the conclusions of organizing bodies, especially the IPCC, cannot be said to reflect scientific “consensus” in any meaningful sense of that word. Instead, they reflect a political movement that has commandeered science to the service of its agenda. This is “post-normal science”: the long-dreaded arrival of deconstructionism to the natural sciences, according to which scientific quality is determined not by its fidelity to truth, but by its fidelity to the political agenda.

It seems unlikely that taking the PNS plunge would appreciably improve the U.S. public’s perception of the credibility, legitimacy and salience of climate-change assessments. This probably says more about Americans than it does about the analytic force of the PNS model.

Let’s face it. Americans do not agree on a whole hell of a lot. And they never have. Many U.S. institutions were deliberately designed to tolerate the coexistence of free states and slave-owning states. Ironically, Americans appear to agree more on climate-change science than other high-profile scientific controversies like the safety of genetically-modified organisms.

National Science Foundation

While it pains me to admit this, I am increasingly convinced that the IPCC’s role in assessing the science of climate change needs to be scaled back. The IPCC was an overly optimistic experiment in international governance designed for a world that never materialized.  The U.N. General Assembly established the IPCC in the months immediately preceding the fall of the Berlin Wall. Only two few years later, the IPCC’s first assessment report and the creation of the U.N. Framework Convention on Climate Change coincided with the collapse of the Soviet Union and the end of the Cold War.

A new world order seemed to be dawning in those days, which is probably why it seemed like a good idea to ask scientists to tell us what constitutes “dangerous climate change.”   Two decades and two world trade towers later, the world is a decidedly less hospitable place for institutions like the IPCC.

The proof is in the pudding – or, in this case, the atmosphere.

Climate Change Tumbles Down Europe’s Political Agenda as Economic Worries Take the Stage (N.Y. Times)

By JEREMY LOVELL of ClimateWire. Published: October 13, 2011

LONDON — Climate change has all but fallen off the political agenda across Europe as the resurging economic crisis empties national coffers and shakes economic confidence, and the public and the press turn their attention to more immediate issues of rising fuels bills and joblessness, analysts say.

Sputtering economies, a shift of attention to looming elections and the prospect of little or no movement in the December climate talks in Durban, South Africa, have combined to take the political momentum out of an issue that was a major cause in Europe.

“It is way down the agenda and will not feature in elections,” said Edward Cameron, director of the World Resources Institute think tank’s international climate initiative, on the sidelines of a meeting on climate change at London’s Chatham House think tank. “At a time of joblessness and fiscal crises, it is very difficult to advance the climate change issue.”

That is as true for next year’s presidential elections in the United States as it will be in France, despite the fact that there has been a series of environmental disasters, from the Texas drought this year to Russia’s heat wave and consequent steep rise in wheat prices last year.

According to acclaimed NASA scientist James Hansen, who has been warning of impending climatic doom for decades, the lack of focus on these events is in no small part due to the fact that scientists are poor communicators while the climate change skeptics have mounted a smoothly run campaign to capitalize on any mistakes and admissions of uncertainty.

“There is a strong campaign by those people who want to continue the fossil fuel business as usual. Climate contrarians … have managed in the public’s eye to muddy the waters enough that there is uncertainty why should we do anything yet,” he said on a visit to London’s Royal Society for a meeting on lessons to be learned from past climate change battles.

“They have been winning the argument in the last several years, even though the science has become clearer,” he added.

Nuclear power issue distracts Berlin

In Germany, where a generous feed-in tariff scheme has produced some 28 gigawatts of wind power capacity and more than 18 GW of solar photovoltaic capacity, Chancellor Angela Merkel’s coalition government was forced into an abrupt U-turn on a controversial move to extend the lives of the country’s fleet of nuclear power plants. There was a political revolt after the March 11 nuclear disaster at Fukushima in Japan.

The oldest seven of Germany’s nuclear plants were closed immediately after Fukushima and will now never reopen, while the remainder will close by 2022.

This has had the perverse effect in a country proud of its renewable energy efforts of increasing the use of coal-fired power plants and increasing the likelihood of new coal- or gas-fired plants being built. The price tag will include higher carbon emissions at exactly the time that the Germany along with the rest of the European Union is pledged to cut emissions.

While political observers believe the climate change issue will come back to the fore at some point in Germany — a country where the Greens have played a pivotal political role — the nuclear power issue is so politically charged that it is off the agenda for now.

Even in the United Kingdom, which has a huge wind energy program and where the Conservative-Liberal Democrat coalition came to power 15 months ago pledging to be the “greenest government ever,” there are major signs of backsliding. A long-awaited energy bill has been shelved, and renewable energy support costs and carbon emission reduction targets are either under review or about to be.

At the Conservative Party’s annual conference earlier this month, climate change was consigned to a brief debate on the opening Sunday, when delegates were mostly just arriving and finding their way around or still traveling to get there.

Damned by faint praise in London

Prime Minister David Cameron did not mention the issue in his speech to the conference — a performance that usually sets the broad agenda for the following year — and Chancellor of the Exchequer George Osborne caused environmental outrage but satisfaction to the party’s right wing by pledging that the United Kingdom would not go any faster than its E.U. neighbors on emission cuts.

This is despite the fact that the United Kingdom has a legal target to cut its carbon emissions by at least 80 percent below 1990 levels by 2050, with cuts of 35 percent by 2022 and 50 percent by 2025, whereas the European Union’s goal is 20 percent by 2020.

It was widely reported that the 2022 target was only agreed to after a major battle in the Cabinet between supporters of Conservative Osborne and those of Liberal Democrat Energy and Climate Change Minister Chris Huhne. It has since been announced that the carbon targets will be reviewed in 2014.

Even in London, where charismatic Conservative Mayor Boris Johnson came to power in 2008 in part on a green ticket, the issue has largely been parked and replaced by transport in the run-up to next year’s mayoral elections. The city’s aging transport system is feared likely to come under massive strain during the 2012 Olympic Games.

Then there is the strange case of a strategic plan on adapting London to climate change, the draft of which was launched with great fanfare and declarations of urgency in February 2010. It was on the brink of publication in September 2010, but after that, it appeared to have vanished without trace.

At the same time, most members of City Hall’s climate change team, set up under the previous Labour administration, have been moved to other jobs.

‘Too difficult — and not a vote winner’

“Political leaders get it, but the treasuries don’t. The men with the money don’t want to be first movers,” said Nick Mabey, co-founder of environmental think tank E3G. “But the political froth has gone. It has become too difficult — and not a vote winner.”

Compounding that problem, at least in the United Kingdom, has been a series of reports underscoring the likely high cost to households of green energy policies at a time when the prices of domestic electricity and gas are already rising sharply.

A recent opinion poll found that the climate change issue has been replaced by concerns over rising fuel bills and energy security.

But Mabey is not too concerned. While the subject may be off the immediate political agenda, behind the scenes, the more enlightened corporate leaders and investment fund managers have been making their own calculations. They are moving their money into the low-carbon economic transformation that in some cases is already profitable and in many eyes essential and inevitable.

The main danger, they say, is that if climate change as a driver of action is allowed to languish too long and become too invisible while energy becomes the main motivator, it will become far harder to resurrect climate change.

For Mabey and WRI’s Cameron, while the deep and seemingly returning global economic crisis has proved a serious distraction internationally as well as domestically, all is not lost.

For a number of reasons, including the rise of a new and major climate player — China — and a series of new scientific reports on climate change due over the next two or three years, 2015 will be the next pivotal moment for the world to take collective action, they say.

“Climate change doesn’t keep people awake at night. Our task for the next few years is to move it back up the political agenda again,” said WRI’s Cameron.

Little Ice Age Shrank Europeans, Sparked Wars (NetGeo)

Study aims to scientifically link climate change to societal upheaval.

Brian Handwerk, for National Geographic News

Published October 3, 2011

Pockmarked with wars, inflation, famines and shrinking humans, the 1600s in Europe came to be called the General Crisis.

But whereas historians have blamed those tumultuous decades on growing pains between feudalism and capitalism, a new study points to another culprit: the coldest stretch of the climate change period known as the Little Ice Age.

(Also see “Sun Oddly Quiet—Hints at Next ‘Little Ice Age’?”)

The Little Ice Age curbed agricultural production and eventually led to the European crisis, according to the authors of the study—said to be the first to scientifically verify cause-and-effect between climate change and large-scale human crises.

Prior to the industrial revolution, all European countries were by and large agrarian, and as study co-author David Zhang pointed out, “In agricultural societies, the economy is controlled by climate,” since it dictates growing conditions.

A team led by Zhang, of the University of Hong Kong, pored over data from Europe and other the Northern Hemisphere regions between A.D. 1500 to 1800.

The team compared climate data, such as temperatures, with other variables, including population sizes, growth rates, wars and other social disturbances, agricultural production figures and famines, grain prices, and wages.

The authors say some effects, such as food shortages and health problems, showed up almost immediately between 1560 and 1660—the Little Ice Age’s harshest period—during which growing seasons shortened and cultivated land shrank.

As arable land contracted, so too did Europeans themselves, the study notes. Average height followed the temperature line, dipping nearly an inch (two centimeters) during the late 1500s, as malnourishment spread, and rising again only as temperatures climbed after 1650, the authors found.

(Related: “British Have Changed Little Since Ice Age, Gene Study Says.”)

Others effects—such as famines, the Thirty Years’ War (1618-48), or the 164 Manchu conquest of China—took decades to manifest. “Temperature is not a direct cause of war and social disturbance,” Zhang said. “The direct cause of war and social disturbance is the grain price. That is why we say climate change is the ultimate cause.”

The new study is both history lesson and warning, the researchers added.

As our climate changes due to global warming (see interactive), Zhang said, “developing countries will suffer more, because large populations in these countries [directly] rely on agricultural production.”

Índios invadem obras de Belo Monte e bloqueiam Transamazônica (FSP)

27/10/2011 – 14h21

AGUIRRE TALENTO
DE BELÉM

O canteiro de obras da hidrelétrica de Belo Monte, localizado no município de Vitória do Xingu (oeste do Pará, a 945 km de Belém), foi invadido na manhã desta quinta-feira (27) em um protesto de indígenas, pescadores e moradores da região.

Eles também bloquearam a rodovia Transamazônica na altura do quilômetro 52, onde fica a entrada do canteiro de obras da usina.

O protesto, que começou às 5h da manhã, foi organizado durante seminário realizado nesta semana, em Altamira (também no oeste, a 900 km de Belém), que discutiu os impactos da instalação de usinas hidrelétricas na região.

Os seguranças permitiram a entrada dos manifestantes sem oferecer resistência, e os funcionários da empresa não apareceram para trabalhar. Com isso, as obras estão paradas.

“Acreditamos que a empresa ficou sabendo de nossa manifestação e não quis entrar em confronto”, afirmou Eden Magalhães, secretário-executivo do Cimi (Conselho Indigenista Missionário), uma das entidades participantes do protesto.

A Polícia Rodoviária Federal confirmou a ocorrência do protesto, mas ainda não sabe estimar a quantidade de pessoas presentes.Segundo ele, há cerca de 600 pessoas no local, entre índios, pescadores, população ribeirinha e até estudantes.

Os manifestantes exigem a presença de algum integrante do governo federal no local e pedem a paralisação das obras.

Ontem, foi adiado mais uma vez o julgamento na Justiça Federal sobre o licenciamento da usina de Belo Monte. O julgamento está empatado com um voto a favor da construção da usina e um voto contra. Falta o voto de desempate, mas ainda não há previsão de quando o processo voltará a ser colocado em pauta.

 

Novo Maracanã já nasce velho (O Globo)

André Trigueiro

O Globo, 27/10/11

O projeto do novo Maracanã confirma a exclusão de um item absolutamente importante para que qualquer projeto de engenharia do gênero possa ser chamado de “moderno e sustentável”. Apesar do variado cardápio de estádios de futebol espalhados pelo mundo com aproveitamento energético do sol, a caríssima obra de reconstrução do Maracanã – quase 1 bilhão de reais – ignorou essa possibilidade.

Estranho que isso tenha acontecido num país onde o sol brilha em média 280 dias por ano. Ainda mais estranho que isso tenha acontecido na cidade que sediou a Rio-92, que vai sediar a Rio+20, e que está situada na mesma faixa de exposição solar que Sidney, na Austrália, que se notabilizou por realizar os primeiros Jogos Verdes da História, inteiramente abastecidos de energia solar.

Cobri como jornalista os Jogos de Sidney em 2000 e lembro-me das imensas estruturas com placas fotovoltaicas que captavam energia solar para iluminar as competições no estádio olímpico, no Superdome e em todas as instalações esportivas. A Vila Olímpica com 665 casas se transformou no maior bairro dotado de energia solar do planeta. O porta-voz do Comitê Olímpico Internacional, o australiano Michael Bland, justificou assim os investimentos em energia solar: “Queremos fazer com que a energia solar se torne popular em todos os países. É ridículo que, na Austrália, todas as casas não usem um captador de energia solar. Temos os telhados, temos o sol, e os desperdiçamos. É um jeito estúpido de levar a vida”.

Que estupidez a nossa desperdiçar a imensa área das marquises do novo Maracanã – quase 29 mil metros quadrados – que poderiam abrigar um vistoso conjunto de placas fotovoltaicas capazes de gerar energia elétrica para até 3.000 domicílios. O custo varia de dez a vinte milhões de reais, dependendo da tecnologia empregada. Alguém poderá dizer: “É caro demais! Não vale a pena”. Mas será que a forma usual de comprar energia está valendo a pena?

Vivemos num país onde, segundo o IBGE, a tarifa de energia elétrica subiu mais do que o dobro da inflação oficial nos últimos 15 anos. A opção pelo solar – embora mais cara – oferece como vantagem a amortização do investimento em alguns poucos anos.

Alguém poderá dizer que a nova marquise – mais leve – poderia não suportar as tradicionais placas fotovoltaicas. Pois que se pensasse numa estrutura compatível. O que está em jogo é a possibilidade de tornar o estádio útil mesmo em dias que não aconteçam partidas de futebol. O Maracanã poderia ser uma usina de energia – ainda que com potência modesta – que além do benefício direto de gerar eletricidade, funcionaria também como elemento indutor de mais pesquisas e investimentos em energia solar no Brasil.

E quem disse que o custo de instalação de um projeto como esse só seria possível com recursos públicos? Se houvesse vontade política para promover inovação tecnológica no setor energético usando o novo Maracanã como garoto-propaganda, seria perfeitamente possível sondar o interesse de grandes empresas com know-how em energia solar que aceitassem instalar os equipamentos fotovoltaicos a custo zero, sem ônus para o governo. E o que essa empresa ganharia em troca? O direito de explorar a imagem do Maracanã como “estádio solar” graças à tecnologia oferecida pela empresa.

Alguém duvida que a imagem aérea do estádio tanto na Copa de 2014 quanto nas Olimpíadas de 2016 alcançará bilhões de telespectadores pelo mundo? É mídia espontânea, super-exposição positiva de imagem, e tudo aquilo que um bom negociador não levaria mais do que alguns minutos para convencer o investidor a botar a mão no bolso e bancar a ideia.

Com recursos públicos ou privados, o certo era fazer. Não basta instalar alguns coletores solares para aquecer a água do banho usadas pelos atletas nos vestiários. É pouco. Se os responsáveis pelo projeto do Maracanã marcaram um gol contra desprezando o sol, os estádios de Pituaçu, em Salvador, e Mineirão, em Belo Horizonte, terão a energia solar como aliada para a produção de energia elétrica. Acorda Rio! Maracanã sem energia solar é como o Rio sem praia. Infelizmente os cariocas continuarão usando o sol apenas para se bronzear.Símbolo da sustentabilidade por suas belezas naturais e por sediar grande conferências ambientais da ONU, o Rio de Janeiro continua com um Maracanã aquém do que merece.

 

 

Comitês de Bacias vão apresentar moção contra reforma do Código Florestal (Ascom da ANA)

JC e-mail 4372, de 26 de Outubro de 2011.

Reunidos em São Luis (MA) no 13º Encontro Nacional de Comitês de Bacias Hidrográficas, representantes de comitês de todo o Brasil vão apresentar na sexta-feira (28) manifestação contra a redução das Áreas de Proteção Ambiental.

Representantes de Comitês de Bacias Hidrográficas de várias regiões do País preparam moção contra a redução das áreas de proteção ambiental às margens dos rios, em protesto contra o texto da reforma do Código Florestal, aprovado na Câmara dos Deputados em maio, que permite o uso das áreas de preservação permanente (APPs). O texto tramita agora no Senado e deve ir a plenário até o final do ano.

A moção será apresentada na sexta-feira (28), último dia do 13º Encontro Nacional de Comitês de Bacias Hidrográficas (Encob), que começa hoje em São Luis (MA).

Atualmente, o Brasil possui cerca de 180 Comitês, sendo dez em rios federias, com representações de diferentes segmentos da sociedade, espalhados por várias bacias. Ao todo, são mais de 50 mil pessoas engajadas na defesa dos recursos hídricos. Esses comitês funcionam como parlamentos da água, pois são formados por usuários locais dos recursos hídricos; organizações não governamentais; sociedade civil e representes do poder público nos três níveis (municipal, estadual e federal), que se reúnem em sessões plenárias.

A Agência Nacional de Águas (ANA) dá apoio técnico aos comitês federias e os órgãos gestores locais, aos estaduais, conforme determina a Lei 9.433 de 1997, conhecida como Lei das Águas, que estabeleceu a Política Nacional de Recursos Hídricos (PNRH) e criou o Sistema Nacional de Gerenciamento de Recursos Hídricos (Singreh). Todos os anos, representantes de comitês de bacia se reúnem para fazer um balanço da gestão dos recursos hídricos, da atuação desses arranjos locais e debater os desafios da implementação da PNRH. Este ano, porém, a reforma do Código Florestal dominou a cerimônia de abertura do 13º Encob, na noite de ontem (25), em São Luís.

“O Encob é o maior encontro nacional de água do planeta, portanto, reúne a visão de vários segmentos da sociedade, de usuários a pesquisadores, gestores e sociedade civil”, disse o diretor-presidente da ANA, Vicente Andreu. “É fundamental que haja uma forte sinalização ao Congresso. O tempo é curto e precisamos fazer chegar aos senadores uma posição muito firme”, completou. Em abril, a ANA divulgou uma Nota Técnica que explica as razões pelas quais a Agência defende a manutenção da cobertura florestal em torno dos rios na proporção atual estabelecida pelo Código Florestal, ou seja, no mínimo 30 metros. O projeto de lei propõe reduzir as áreas de proteção mínima para 15 metros. As matas ciliares são fundamentais para proteger os rios e garantir a qualidade das águas.

O deputado federal Sarney Filho (PV-MA) prometeu levar as análises do Encob à Subcomissão da Rio+20 da Câmara dos Deputados. “Todos sabemos que nossos rios estão ameaçados pelo lançamento de esgotos, pelo desmatamento das matas ciliares e agora pela reforma do Código Florestal”, disse.

Para o presidente da Rede de Organismos de Bacia (Rebob) e coordenador geral do Fórum Nacional dos Comitês de Bacias Hidrográficas, Lupércio Ziroldo Antônio, “aos olhos do mundo o Brasil é considerado uma potência hídrica por possui 13% da água do planeta e alguns dos maiores aqüíferos do mundo, por isso, precisa dar exemplo, principalmente nos próximos meses, quando haverá dois encontros internacionais importantes sobre meio ambiente e recursos hídricos: o Fórum Mundial da Água, em março de 2012,em Marselha, na França; e a Rio+20, em junho de 2012”.

Vários dos temas que estão sendo debatidos no Encob esta semana poderão ser abordados na Rio+20. Entre as proposições da ANA para o encontro no Rio estão a criação de um fundo para pagamentos por serviços ambientais para a proteção de nascentes, no moldes do Programa Produtor de Água da ANA; a criação de um programa global de pagamento para o tratamento de esgoto, baseado no Prodes (Programa de Despoluição de Bacias Hidrográficas) da ANA; e a criação de um órgão de governança global da água, no âmbito das Nações Unidas.

A programação do Encob inclui cursos de gestão de recursos hídricos para membros dos comitês de bacia e órgãos gestores locais de recursos hídricos, reuniões de comitês interestaduais, reunião da seção Brasil do Conselho Mundial da Água, oficina de adaptação às Mudanças Climáticas na Gestão dos Recursos Hídricos, além de mesas de debates sobre nascentes de centros urbanos, o papel dos comitês na universalização do saneamento, entre outras discussões.

Brasil é país-modelo em PSA, mas precisa intensificar atuação (Valor Econômico)

JC e-mail 4370, de 24 de Outubro de 2011.

Ainda sem regulamentação nacional, o Pagamento por Serviços Ambientais (PSA) se expande no Brasil, mas a passos lentos.

O estudo Pagamento por Serviços Ambientais na Mata Atlântica, feito pela Agência de Cooperação Internacional Alemã (GIZ), levantou quase 80 programas de PSA na região. São 40 projetos de PSA de água, 33 de carbono e 5 em biodiversidade. “As iniciativas aqui estão se proliferando rapidamente. Mas ainda são projetos isolados, que precisam ganhar escala”, afirma Susan Seehusen, assessora técnica em Economia de Meio Ambiente da GIZ. Com 22% de sua área original, a Mata Atlântica fornece serviços ambientais para comunidades tradicionais e rurais de seu entorno e a comunidade global.

De maior abrangência, os projetos de água contam com fontes de recursos de orçamentos públicos e verba do Comitê de Bacias Hidrográficas lideradas por prefeituras municipais e empresas do setor. O programa Produtor de Água, da Agência Nacional de Água (ANA), remunera produtores rurais e impulsiona o desenvolvimento do setor. Com o pagamento desses recursos humanos mais ações de restauração e conservação florestal, o custo anual dos projetos vai de R$ 200 mil a R$ 2,5 milhões por ano. Hoje, programas em fase inicial envolvem cerca de 350 produtores e beneficiam 22,2 milhões de pessoas.

Ligados a projetos de neutralização de CO2, os PSA de carbono se concentram na região do Pontal de Paranapanema, na tríplice fronteira São Paulo, Paraná e Minas Gerais, em terras de 10 hectares e 50 hectares. Já proprietários de áreas de mais de 100 hectares aderem aos programas a fim de atrair investidores.

Já atividades de proteção à biodiversidade são as menos apoiadas. “Nessa área, há baixa disposição para pagar. As pessoas se aproveitam do serviço mas não pagam por eles, são os chamados caronistas”, ressalta Susan.

A ampliação dos programas de PSA esbarra em problemas de governança, nos altos investimentos e na falta de regulamentação – tramita no Congresso o projeto de lei nº 792/2007, que visa instituir uma política nacional e criar um programa nacional e um fundo de PSA. Restaurar 1 hectare de terra custa de R$ 10 mil a R$ 20 mil. Então, ganham pontos ações que visam diminuir a pobreza e melhorar a distribuição de renda, como o ICMS-Ecológico, em regiões do Paraná.

Ainda assim, o Brasil é um dos países mais avançados em PSA e serve como modelo para outros países, de acordo com Peter May, professor de pós-graduação em Desenvolvimento, Agricultura e Sociedade da Universidade Federal Rural do Rio de Janeiro. Membro da International Society for Ecological Economics (ISEE), May faz estudo comparativo global sobre Redução das Emissões do Desmatamento e Degradação Florestal (Redd) e divulga dados estratégicos para formuladores de políticas públicas. “Em relação a outros países, temos um mercado agropecuário maduro sem ilegalidades e donos de terras mais instruídos. Estados como Espírito Santo, São Paulo, Amazonas e Acre criaram leis próprias”, diz. Segundo ele, a Costa Rica é modelo clássico com legislação e PSA desenvolvidos. Já Colômbia, Peru, México e Equador têm políticas próprias, mas se espelham nos nossos moldes.

Para May, além de quadro regulatório, a política de PSA deve ser incorporada pelo Código Florestal. Ele alerta ainda que o Brasil carece de experiências mais concretas e resultados práticos. O que, no entanto, exige pesquisa e monitoramento que podem sair mais caros que o projeto.

Can indigenous peoples be relied on to gather reliable environmental data? (Stanford University)

Public release date: 13-Oct-2011
Contact: Louis Bergeron
Stanford University

No one is in a better position to monitor environmental conditions in remote areas of the natural world than the people living there. But many scientists believe the cultural and educational gulf between trained scientists and indigenous cultures is simply too great to bridge — that native peoples cannot be relied on to collect reliable data.

But now, researchers led by Stanford ecologist Jose Fragoso have completed a five-year environmental study of a 48,000-square-kilometer piece of the Amazon Basin that demonstrates otherwise. The results are presented in a paper published in the October issue of BioScience and are available online.

The study set out to determine the state of the vertebrate animal populations in the region and how they are affected by human activities. But Fragoso and his colleagues knew they couldn’t gather the data over such a huge area by themselves.

“The only way you are going to understand what is in the Amazon in terms of plants and animals and the environment, is to use this approach of training indigenous and the other local people to work with scientists,” Fragoso said.

“If I had tried to use only scientists, postdocs and graduate students to do the work, it would not have been accomplished.”

Fragoso and his colleagues worked in the Rupununi region in Guyana, a forest-savanna ecosystem occupied by the Makushi and Wapishana peoples. They support themselves primarily through a mix of subsistence hunting, fishing and agriculture, along with some commercial fishing, bird trapping and small-scale timber harvesting.

The researchers recruited 28 villages and trained more than 340 villagers in methods of collecting field data in a consistent, systematic way. The villagers were shown how to walk a transect through an area, recording sightings and signs of animals, noting the presence of plants that animals feed on and marking their observations on a map.

The training was not without its challenges. Many of the older villagers were expert bushmen, but could not read, write or do arithmetic. Many of the younger villagers, who had received some formal education, were literate but lacked knowledge of the animals and plants in the wilds around their communities. So researchers paired younger and older villagers to go into the field together. All the villagers were paid for the work they did.

Part of any scientific study is validating the accuracy of the data and Fragoso’s team knew that no matter how well they trained their indigenous technicians, they would have to analyze the data for errors and possible fabrications.

The researchers used a variety of methods, including having a different team of technicians or researchers walk some transects a second time, to verify that they were regularly walked by technicians, that data were accurate and that reported animal sightings were plausible. They also had technicians fill out monthly questionnaires about their work and did statistical analyses for patterns of discrepancy in the data.

The most consistently accurate data was recorded by technicians in communities that had strong leadership and that were part of a larger indigenous organization, such as an association of villages. Fabricated data was most common among technicians from villages unaffiliated or loosely affiliated with such an association, where there was less oversight.

The other main factor was whether a technician’s interest in the work went beyond a salary, whether he was interested in acquiring knowledge.

After all the data verification was done, the researchers found that on average, the indigenous technicians were every bit as able to systematically record accurate data as trained scientists. They were also probably better than scientists at detecting animals and their signs.

“This is the first study at a really large scale that shows that consistently valid field data can be collected by trained, indigenous peoples and it can be done really well,” Fragoso said. “We have measured the error and discovered that 28 percent of villages experienced some data fabrication. This originated from about 5 percent (18 out of 335) of technicians fabricating data, which may not be much different than what occurs in the community of scientists.”

“The indigenous technicians are no more corrupt, sloppy, or lazy than we are,” he said, noting that every year papers published in peer-reviewed science journals have to be withdrawn because of falsified or inaccurate data.

In all, the technicians walked over 43,000 kilometers through the wild, recording data. That’s once around the world and then some. They logged 48,000 sightings of animals of 267 species. They also recorded over 33,000 locations of fruit patches on which various species of animals feed.

Working with indigenous technicians enables researchers to gather far more data over a much larger area than would otherwise be possible, Fragoso said. Such data can be used by governments, scientists and conservation organizations to get an understanding of remote areas, from tropical forests to the Arctic tundra.

Fragoso is optimistic about how the results of the study will be received by the scientific community.

“I have presented this study to some pretty unreceptive groups, such as at scientific meetings, but by the end of the presentation audience members are either convinced, or at least they doubt their argument, which is a major achievement in itself,” he said.

“One thing about the scientific community – if you have enough solid data and the analysis is well done, there is very little you can argue against.”

Tim Ingold: Projetando ambientes para a vida – um esboço (Blog Noquetange)

Projetando ambientes para a vida – um esboço*
Por Maycon Lopes
10/10/2011

Imbuído de pensar uma antropologia do vir-a-ser, uma antropologia do devir, quer dizer, aquela que não seja sobre as coisas, mas que se mova com elas, Ingold esboçou, no que os organizadores chamaram desde o início da série de conferências na UFMG de sua “grande conferência”, críticas e proposições para trilharmos o futuro. Trilhar não se trata de percorrer um caminho pré-definido; é deixar pegadas no seu percorrer, marcar com trilho, traçar. O traçado é como um desenho, um projeto, e o ato de fazê-lo já nos desloca da condição de “meros usuários” do design. Para Ingold, os designs têm de falhar, para que o futuro possa deles se apropriar, destruí-los. Eles poderiam ser pensados como previsões – e toda previsão é errada. Ou, seguindo a linha de análise deleuziana, o design poderia ser compreendido como uma tentativa de controlar o devir.

Tim Ingold propõe que ele (o design) seja concebido, no âmbito de um processo vital cuja essência é de abertura e improvisação, como um aspecto, menos como meta pré-determinada que como a continuidade de um andamento. Neste sentido, o design seria produção de futuros e não definição de. Essa ideia contudo contrasta – e esse é o ponto, creio eu, de Ingold e desse post – com a forma como tem sido predominantemente compreendida a natureza no discurso tecnocientífico: com objetivos precisos, o ambiente seria nada mais que um meio, uma coisa manipulável, vida sequestrada tendo em vista a atingir determinados fins. A natureza dos cientistas e dos criadores de política é conhecida através de cálculos, gráficos, imagens independentes daquelas do mundo que conhecemos (ou mundo fenomenal) e com o qual estamos familiarizados pelo próprio habitar. Essa dissociação artificial, que para nós aparece na figura do “globo”, espaço a que não sentimos pertencer, em contraposição com a terra, que de fato habitamos, é um modo nada adequado de abordar as constantes ameaças sofridas pela natureza. A mesma dissociação provoca uma lacuna entre o mundo diário e o mundo projetado pelos instrumentos de conhecimento a que me referi anteriormente, opondo conhecimento do habitante a conhecimento científico, como se os cientistas não habitassem mundo.

Uma expressão muito em voga como “desenvolvimento sustentável”, em geral usada tanto por políticos como por grandes corporações com intuito de proteger o lucro, é amparada por registros contábeis, ou pela perspectiva, segundo Tim Ingold do ex-habitante. Nós outros, habitantes, não temos acesso a essa linguagem contábil, e somos assim furtados da responsabilidade de cuidar do meio ambiente, sendo dele (verticalmente) expelidos, em vez de fazer do mesmo um projeto comum, pela via do que Ingold denominou de “projetar ambientes para a vida”. Repousaria pois na unidade da vida esse elo ontológico, unidade esta que nem o catálogo taxonômico “biodiversidade” e nem a concepção kantiana de superfície – palco das nossas habilidades – dão conta. Tim Ingold se esforça, em nome de uma vida social sempre indivisível da vida ecológica (se é que é possível já assim polarizá-las – ressalta Ingold), por uma genealogia da unidade da vida, uma partilha histórica entre sociedade e natureza, sendo a última em geral concebida como facticidade, coisa bruta do mundo.

Para Ingold os conceitos são inerentemente políticos, e deste modo é interessante para alguns distinguir humanos de inumanos, que, embora estejam num único mundo, apenas os primeiros, pelo viés da “ação humana”, são passíveis de construir. Seriam assim os humanos “menos naturais”, todavia envolvidos mutuamente ao longo do mundo orgânico. Que pensar a respeito do vento, do sol, das árvores e suas raízes (onde residiria o seu caminhar)? Ele propõe, a fim de evitar – e agravar – essa infeliz dicotomia, a concepção de ambiente como uma zona de envolvimento mútuo, cujo relacionamento entre os seres se dá justamente por feixes de linhas, como luz, como ar, e caminhos. Contra as tentativas coercitivas de suprimir o ambiente cobrindo-o de superfícies duras/impermeáveis, Ingold oferece o rolar sobre o mundo e não através do. Segundo ele, o rolar sobre significa o nosso envolvimento com o ambiente, a nossa própria experiência, que difere do global da tecnociência. Aqui se situa o design, mas não o design que inova, e sim o design que improvisa. A inovação seria oriunda de uma leitura de “trás pra frente”, já a improvisação uma leitura do ler para a frente, por onde o mundo se desdobra. Toda improvisação para o antropólogo consiste em criatividade, e criatividade implica já crescimento. O design não prevê, o design antecipa.

Assim a sua ideia é a de caminhar com o mundo, “crescer junto”, mas não num mundo pré-ordenado e sim um mundo incipiente. O design não é uma pré-figura, mas um traço, um desenho, uma linha para uma caminhada, no entanto sempre passível de fuga do enredo como personagens de um romance – com vida própria. Ingold então defende o projetar como um verbo intransitivo, responsável – ao contrário do que pensava o pintor Paul Klee, do julgamento da forma como morte – por atribuir vida. Para a proposta de Timothy Ingold, finalmente, seria necessário o aumento da flexibilidade dos habitantes de mundo, em que tensão seria convertida em conversa, em diálogo, em projeto.
