Human carbon emissions to rise in 2019

Here comes another dismal science forecast, with human carbon emissions due to rise this year. Forests may be unable to keep pace as global warming increases.

LONDON, 31 January, 2019 − Stand by for a year in which global warming can only get worse as human carbon emissions climb still further. British meteorologists warn that although 2018 broke all records for greenhouse gas emissions, 2019 will see even more carbon dioxide take up long-term residence in the planetary atmosphere.

And it will happen for two reasons, both of them nominally at least under human control. The overall release of carbon dioxide from power stations, factory chimneys, cement quarries, car exhausts and so on will continue to rise with fossil fuel combustion, even though there has been greater investment than ever in renewable resources such as wind and solar energy.

And those natural “sinks” that absorb extra carbon from the atmosphere and sequester it as living timber in the forests, or bones and shells in the oceans, are expected to under-perform.

This is largely because of natural cyclic variation in the tropical climate, but also partly because humans continue to degrade grasslands and fell or burn the forests that naturally absorb carbon dioxide from the atmosphere and return oxygen for the animal world to breathe.

Hawaii’s unique record

Climate scientists know what is going to happen because they can see the future already written in a unique 60-year-old cycle of data recorded high on a mountaintop in Hawaii, in the Pacific, far from any heavy industry or city pollution that might distort the local chemistry of the atmosphere.

“Since 1958, monitoring at the Mauna Loa observatory in Hawaii has registered around a 30% increase in the concentration of carbon dioxide in the atmosphere,” said Richard Betts, of the UK Met Office’s Hadley Centre.

“This is caused by emissions from fossil fuels, deforestation and cement production, and the increase would have been even larger if it were not for natural carbon sinks which soak up some of the excess CO2.

This year we expect these carbon sinks to be relatively weak, so the impact of record high human-caused emissions will be larger than last year.”

“Deforestation in the Brazilian Amazon increased to around 8,000 square kilometres in 2018, equivalent to losing a football pitch of forest every 80 seconds”

At the heart of the diagnosis is the increasing understanding of the role of the world’s great oceans in managing planetary weather patterns.

A year ago the tropical Pacific was relatively cool, rainfall increased and land-based ecosystems flourished, soaking up atmospheric carbon. In a relatively warm cycle, many regions become warmer and drier, which in turn limits plant growth.

Carbon dioxide ratios in the global atmosphere for most of human history, until the Industrial Revolution and the arrival of the steam age and the internal combustion engine, oscillated at around 280 parts per million (ppm). In the last decade, the ratio reached 400 ppm, and in 2018 peaked at 414.7 ppm in May, before beginning to fall in the northern hemisphere growing season, to rise again in September.

El Niño distortion

Overall, the average for 2018 was 411 ppm, with an uncertainty factor of 0.6 ppm. In 2019, the average is likely to be 2.75 ppm higher still. This would be one of the largest annual rises on record.

The rises in 2015-2016 and in 1997-1998 were higher, but these years’ readings were distorted by the arrival of a dramatic but natural Pacific warming called El Niño, always associated with a sudden and often damaging shift in regional climate patterns far away.

Climate scientists have continued to hope for a global response to such predictions: these are the people who are professionally most aware of the big picture of global change.

Julienne Stroeve of University College London called the news “discouraging, for sure. Last year the extra CO2 was equivalent to melting about 110,000 square kilometres of Arctic Sea ice, or roughly three times the area of Switzerland. Sea ice loss is directly tied to increases in atmospheric CO2.”

Damage to forests

And Jos Barlow, of Lancaster University’s Environment Centre, warned that forest clearance in the tropics continued as a hazard.

Deforestation in the Brazilian Amazon increased to around 8,000 square kilometres in 2018, which is equivalent to losing a football pitch of forest every 80 seconds. This alone would result in CO2 emissions that exceed those of the UK over the same time period.”

Professor Betts called the Mauna Loa record of atmospheric carbon dioxide a “thing of beauty” and a stark reminder of human interference with the planetary climate.

“Looking at the monthly figures, it’s as if you can see the planet ‘breathing’ as the levels of carbon dioxide fall and rise with the seasonal cycle of plant growth and decay in the northern hemisphere. But each year’s CO2 is higher than the last, and this will keep happening until humans stop adding CO2 to the atmosphere.” − Climate News Network

More vegetables, less meat for all our sakes

Researchers are clear: the healthy diet for a healthy planet is more vegetables, less meat. What matters is the food that’s served, and the way it’s produced too.

LONDON, 17 January, 2019 − An international panel of health scientists and climate researchers has prescribed a new diet for the planet: more vegetables, less meat, fresh fruit, wholegrains and pulses, give up sugar, waste less and keep counting the calories.

And if 200 nations accept the diagnosis and follow doctor’s orders, tomorrow’s farmers may be able to feed 10 billion people comfortably by 2050, help contain climate change, and prevent 11 million premature deaths per year.

A commission sponsored by one of the oldest and most distinguished medical journals in the world today provides what it calls the first scientific targets for a healthy diet, from a sustainable food production system, that operates within what its authors term “planetary boundaries.”

The commission is the result of three years’ consultation by 37 experts from 16 countries, among them experts in health, nutrition, environmental sustainability, economics and political governance.

Goal within reach

It addresses the twin problems of global food supply: altogether 3 billion people are either under-nourished, or approaching clinical obesity because they are too well-nourished.

And global food production in its present form is helping to drive global warming and climate change, trigger accelerating biodiversity loss, pollute the rivers, lakes and coasts with ever greater levels of nitrogen and phosphorus run-off, and make unsustainable use of both land and fresh water.

“The food we eat and how we produce it determines the health of people and the planet, and we are currently getting this seriously wrong,” said Tim Lang, a food scientist at the City University of London, and one of the authors.

“ We need a significant overhaul, changing the global food system on a scale not seen before in ways appropriate to each country’s circumstances. While this is uncharted policy territory and these problems are not easily fixed, this goal is within reach and there are opportunities to adapt international, local and business policies. The scientific targets we have devised for a healthy, sustainable diet are an important foundation which will underpin and drive this change.”

“Humanity now poses a threat to the stability of the planet”

The study simultaneously addresses what should be on the global supper table, and how it gets there. It presumes a daily intake for a 70kg active adult male aged 30, or a 60kg woman, of up to 2,500 kilocalories per day, with around 35% of these from wholegrains and tubers.

It recommends a limit of 14 grams of red meat per day, and 500 grams of vegetables and fruits. The global appetite for red meat and sugar must be halved, while consumption of nuts, vegetables, legumes and fruit intake must double.

And it recommends fair shares on a global scale; North Americans chew their way through more than six times the recommended meat portion; people in South Asia right now consume only half what they should.

And across the globe, people depend too much on starchy foods such as potato and cassava: in sub-Saharan Africa, 7.5 times too much. If people adopt a healthy diet and limit the use of processed foods, this would avert between 10.9m and 11.6m premature deaths each year.

Unprecedented change

But the same advice then addresses the global and seemingly intractable problem of managing agriculture so that it serves all and saves the planet for permanent occupation. To make this happen, change is necessary at rates so far without precedent in history.

Somehow, production must be intensified, but without greater destruction of forests and savannah, and while eliminating the use of fossil fuels.

Another of the authors, Johan Rockström, of the Stockholm Resilience Centre and who now directs the Potsdam Institute for Climate Impact Research in Germany, calls it “nothing less than a new global agricultural revolution.”

“The good news is that not only is it doable, we have increasing evidence that it can be achieved through sustainable intensification that benefits both farmer, consumer and planet,” he said.

Planetary perspective needed

“Humanity now poses a threat to the stability of the planet. Sustainability of the food system must therefore be defined from a planetary perspective.”

The study is the latest and most authoritative iteration of a series of research papers that have argued, over and over again, for a change in planetary diet, a shift towards more efficient but also more sustainable  farming methods, and a greater focus on planetary equity.

The message from most of them is that it is, or should be, technically possible to grow food for a hungry planet without wasting productivity and without devastating wildlife and natural ecosystems any further.

Five-point plan

The Lancet Commission proposes a fivefold strategy. It includes campaigns and pricing policies to promote sustainable sources; a shift from high-volume crops to a greater variety of nutrient-rich plants; appropriate agricultural practices; careful governance of land and ocean use, along with protection of natural areas; and a concerted attempt to at least halve food wastage, an issue in high-income countries and in different ways also in poor and middle-income countries.

This is one of a series of studies published by the Lancet to address global problems related to climate: in December the same journal carried an authoritative assessment of the health costs of heat extremes in the decades to come.

Richard Horton, editor in chief of The Lancet, said the issue of global nutrition was “everyone’s and no-one’s problem. The transformation that this Commission calls for is not superficial or simple, and requires a focus on complex systems, incentives and regulations, with communities and governments at multiple levels having a part to play in redefining how we eat.

“Our connection with nature holds the answer, and if we can eat in a way that works for the planet as well as our bodies, the natural balance of the planet’s resources will be restored. The very nature that is disappearing holds the key to human and planetary survival.” − Climate News Network

Tell us more on palm oil sources, say buyers

A British study says consumers must be able to make sustainable choices more easily on products containing palm oil.

LONDON, 4 January, 2019 − Companies selling products which contain palm oil need to be upfront about where it comes from, so as to relieve consumers of the burden of making sustainable choices, a UK study says.

Researchers from the University of Cambridge say companies should not rely simply on purchasers’ own awareness of the need to make environmentally responsible decisions, but should publicly disclose the identities of their palm oil suppliers.

Palm oil production causes deforestation, greenhouse gas emissions from peatland conversion, and biodiversity loss, and the oil is found in many products, often without consumers’ knowledge. It is a common ingredient in foods, body products, detergents and biofuels.

Dr Rosemary Ostfeld is the study’s lead author. She said: “The Roundtable on Sustainable Palm Oil (RSPO) has made efforts to improve the sustainability of palm oil production by creating an environmental certification system for palm oil.

Low uptake

“But currently only 19% of palm oil is RSPO-certified. This means the majority that finds its way into products people buy daily is still produced using conventional practices.

“We wanted to find out if consumers were actively seeking to make a sustainable choice about palm oil. We also explored what extra efforts governments could make to ensure sustainable palm oil consumption.”

The researchers, whose study is published in the journal Environmental Research Letters, surveyed 1,695 British consumers through the market research company YouGov.

Respondents were asked about their awareness of palm oil and its environmental impact; their recognition of “ecolabels” such as Fairtrade, the Soil Association and RSPO; and which ecolabelled products they included in their weekly household shopping.

“Relying on consumers to consciously and regularly include certified products in their shopping has limitations”

The study found that UK consumer awareness of palm oil was high (77%), with 41% of those aware of it viewing it as “environmentally unfriendly”. Yet almost no consumers were aware of the RSPO label that showed a product contained sustainably-produced palm oil.

“In terms of label recognition versus action, 82% of people recognised the Fairtrade label, but only 29% actively buy Fairtrade products,” said Dr Ostfeld.

“Only five per cent recognised the RSPO label – the same as a fictional label we put into the survey as a control. Of that small number, only one per cent said they actively include products with the label in their shopping.”

The low recognition of the RSPO label could be caused by the scarcity of its use by consumer goods companies and retailers.

Action not guaranteed

Dr Ostfeld said: “This may be due in part to reluctance to draw attention to their use of palm oil, or it may be because they fall short of the 95% physical certified palm oil content that used to be needed to use the label.

“Either way, we found that relying on consumers to consciously and regularly include certified products in their shopping has limitations. Our results show that even when consumer awareness of an ecolabel is high, action is not guaranteed.”

To address this problem, the researchers put forward several policy recommendations. Dr Ostfeld explained: “Palm oil is more efficient to produce than other vegetable oils and plays a vital role in the livelihoods of millions of people, so banning it is not plausible. Instead, the goal should be to encourage sustainable palm oil production.

“We recommend governments require consumer goods companies and retailers to buy identity-preserved certified palm oil, which can be traced back to the individual plantation. If national targets must be met with identity-preserved certified palm oil, demand for it will increase. It will also enable unsustainable practices to be uncovered more easily.

Disclosure needed

“Companies should also publicly disclose their palm oil suppliers. This will help consumers know if they’re sourcing their palm oil from growers who use best practices.

“We believe these measures could promote a more rapid move towards sustainable palm oil consumption, and higher levels of accountability throughout the supply chain.”

Some campaigners argue that sustainability standards, including certification schemes, can have a wider effect by, for example, helping to shape governments’ policies and to steer investment into research.

Amazon in peril as Brazil cools on climate

The man who will become Brazil’s president next month is cold-shouldering moves to tame the pace of climate change, leaving the Amazon in peril.

SÃO PAULO, 12 December, 2018 − The election of an extreme rightwing climate sceptic as president will leave the Amazon in peril, because it radically alters Brazil’s position on climate change.

That process has already begun, with the cancellation of the outgoing president’s invitation to the United Nations to hold its 2019 climate talks, COP-25, in Brasilia.

President-elect Jair Bolsonaro is also threatening to withdraw from the Paris Agreement on tackling climate change, claiming that a plot exists to reduce Brazil’s sovereignty over the Amazon.

While he does not officially take office until 1 January, Bolsonaro has already significantly altered Brazil’s position by cancelling the present government’s offer to host COP-25 only days after it was officially made by the departing president, Michel Temer.

Due for confirmation

It was due to be confirmed at this year’s UN talks (COP-24) in the Polish city of Katowice. The COPs (meetings of the parties to the UN Framework Convention on Climate Change) are rotated between the world’s five regions, and 2019 was to be the turn of Latin America and the Caribbean.

For André Nahur, a biologist and the coordinator of WWF Brazil’s programme for climate change and energy, it is a sign that under Bolsonaro Brazil will abdicate its role as a leader in environmental questions.

He said: “Brazil has been a protagonist in international climate talks, exercising an important role in diplomatic efforts to reduce greenhouse gases … in order to achieve world targets. Brazil’s participation is vital, because at the moment it is the seventh largest producer of greenhouse gases.”

He added that the withdrawal of Brazil’s offer for COP-25 will affect the country’s economic development: “All scenarios show that in countries concerned with climate change, GDP has grown and generated jobs.”

“I am not in favour of signing a trade deal with powers that do not respect the Paris agreement”

The Climate Observatory, a Brazilian NGO (Observatório do Clima) says Bolsonaro’s decision means that Brazil is abdicating its role in one of the few areas where the country is not just relevant but necessary.

“Ignoring the climate agenda, the government is also failing to protect the population affected by a growing number of extreme weather events. Unfortunately they do not stop happening just because some people doubt their causes,” it said.

To try to justify his stated intention to withdraw Brazil from the Paris Agreement Bolsonaro has invoked the existence of a forgotten project once proposed by Gaia Colombia, known as the Triple A.

He said: “What is the ‘Triple A? It’s a big strip between the Andes, the Amazon and the Atlantic … The idea is to turn it into an ecological corridor.” This, says Bolsonaro, could result in Brazil losing its sovereignty over the area.

Doubtful explanation

The ambitious plan for the corridor, covering over 500,000 square miles of rainforest, surfaced several years ago, and is credited to Martín von Hildebrand, founder of the Gaia Amazonas NGO, but it has never been taken seriously, and it is certainly no part of the Paris Agreement.

While the president-elect evoked this non-existent problem to justify his dislike of the Paris deal, French president Emmanuel Macron hinted at the real consequences of leaving the treaty, declaring: “I say clearly that I am not in favour of signing a trade deal with powers that do not respect the Paris agreement.”

Brazil’s new position also leaves it out of step with the BRICS, the group of five big emerging countries (Brazil, Russia, India, China and South Africa).

They produced a statement at the recent G20 meeting in Buenos Aires affirming their commitment to the “full implementation of the Paris Agreement, and the importance and urgency of guaranteeing funds for the Green Climate Fund”, to increase the developing countries’ capacity for mitigation and adaptation.

Faith in Trump

Bolsonaro has chosen as his foreign minister a diplomat, Ernesto Araujo, who scoffs at what he calls “climatism” and believes that US president Donald Trump is the saviour of the Christian values of the Western world, while globalisation is a communist plot.

If Brazil were just a small banana republic this would not matter. But the South American giant, the fifth largest country in the world, in both size and population, and ninth largest economy, is too big to ignore, especially as it contains 60% of the Amazon rainforest, the world’s largest tropical forest.

But even before Bolsonaro officially takes office deforestation has soared, hitting its highest level for a decade as loggers and landgrabbers anticipate a loosening of monitoring and enforcement.

For André Nahur, a biologist and the coordinator of WWF Brazil’s programme for climate change and energy, it is a sign that under Bolsonaro Brazil will abdicate its role as a leader in environmental questions.

He said: “Brazil has been a protagonist in international climate talks, exercising an important role in diplomatic efforts to reduce greenhouse gases … in order to achieve world targets. Brazil’s participation is vital, because at the moment it is the seventh largest producer of greenhouse gases.”

He added that the withdrawal of Brazil’s offer for COP-25 will affect the country’s economic development: “All scenarios show that in countries concerned with climate change, GDP has grown and generated jobs.”

“I am not in favour of signing a trade deal with powers that do not respect the Paris agreement”

The Climate Observatory, a Brazilian NGO (Observatório do Clima) says Bolsonaro’s decision means that Brazil is abdicating its role in one of the few areas where the country is not just relevant but necessary.

“Ignoring the climate agenda, the government is also failing to protect the population affected by a growing number of extreme weather events. Unfortunately they do not stop happening just because some people doubt their causes,” it said.

To try to justify his stated intention to withdraw Brazil from the Paris Agreement Bolsonaro has invoked the existence of a forgotten project once proposed by Gaia Colombia, known as the Triple A.

He said: “What is the ‘Triple A? It’s a big strip between the Andes, the Amazon and the Atlantic … The idea is to turn it into an ecological corridor.” This, says Bolsonaro, could result in Brazil losing its sovereignty over the area.

Doubtful explanation

The ambitious plan for the corridor, covering over 500,000 square miles of rainforest, surfaced several years ago, and is credited to Martín von Hildebrand, founder of the Gaia Amazonas NGO, but it has never been taken seriously, and it is certainly no part of the Paris Agreement.

While the president-elect evoked this non-existent problem to justify his dislike of the Paris deal, French president Emmanuel Macron hinted at the real consequences of leaving the treaty, declaring: “I say clearly that I am not in favour of signing a trade deal with powers that do not respect the Paris agreement.”

Brazil’s new position also leaves it out of step with the BRICS, the group of five big emerging countries (Brazil, Russia, India, China and South Africa).

They produced a statement at the recent G20 meeting in Buenos Aires affirming their commitment to the “full implementation of the Paris Agreement, and the importance and urgency of guaranteeing funds for the Green Climate Fund”, to increase the developing countries’ capacity for mitigation and adaptation.

Faith in Trump

Bolsonaro has chosen as his foreign minister a diplomat, Ernesto Araujo, who scoffs at what he calls “climatism” and believes that US president Donald Trump is the saviour of the Christian values of the Western world, while globalisation is a communist plot.

If Brazil were just a small banana republic this would not matter. But the South American giant, the fifth largest country in the world, in both size and population, and ninth largest economy, is too big to ignore, especially as it contains 60% of the Amazon rainforest, the world’s largest tropical forest.

But even before Bolsonaro officially takes office deforestation has soared, hitting its highest level for a decade as loggers and landgrabbers anticipate a loosening of monitoring and enforcement.

Brazil’s Jair Bolsonaro puts Amazon at risk

If their new leader, Jair Bolsonaro, acts as many Brazilians expect him to, the Amazon forest is likely to suffer serious damage.

SÃO PAULO, 16 November, 2018 − The Amazon rainforest, the greatest remaining in the world, faces a new threat − from the policies espoused by Jair Bolsonaro, the ex-army captain who is now Brazil’s president-elect. The forest is globally vital for its ability to store atmospheric carbon released by the burning of fossil fuels.

Bolsonaro has caused alarm both in the country and abroad with his views on the environment. In anticipation of his victory, deforestation in the Amazon region increased by 50% in the three months before the poll.

The Real Time System for Detection of Deforestation in the Amazon region, Deter, which is administered by Brazil’s National Institute for Space Research (INPE) and provides data for environmental inspectors, found that between August and October, the Amazon rainforest lost 1,674 square kilometres, an area bigger than Brazil’s largest metropolis, São Paulo. This was an increase of 48.8% compared to the same months in 2017.

Imazon, an NGO which also monitors deforestation, using a different system called SAD (Deforestation Alert System) registered an even bigger increase of 84% (in Portuguese) compared to 2017.

“Up to 15 million hectares of the Brazilian Amazon is at risk of losing its legal protection”

In the area that showed the greatest increase in illegal deforestation, the border region between the states of Acre and Amazonas, the main cause was cattle ranching. It is the cattle ranchers, together with the soy farmers, who are among Bolsonaro’s most enthusiastic supporters.

But even they were alarmed when he announced, as one of his first measures, the merging of the Ministry of the Environment, one of whose main functions is to enforce environmental laws, with the powerful Ministry of Agriculture, more or less like putting the fox in charge of the chicken coop. Brazil is one of the world’s top exporters of soy and beef, and farmers know they must adhere to the strict environmental and health conditions demanded by importers.

The president-elect’s radical plans also came under fire from eight former environment ministers. In an open letter to Bolsonaro, published in the newspaper Opinião do jornal Folha de São Paulo (in Portuguese), they urged him not to withdraw Brazil from the Paris Agreement on tackling climate change, which, as an enthusiastic fan of Donald Trump, he has said he wants to do.

They point out that Brazil, host to the first Earth Summit in 1992 and to the follow-up 20 years later, Rio+20, is a world leader in sustainable development and the use of renewable energy resources, and, because of the importance of the Amazon rainforest to the world’s climate, a leading player in global environmental policy.

Double disaster possible

To abolish the Environment Ministry and leave the Paris Agreement, they say, would also be disastrous politically and commercially: “We cannot run the risk of international political isolation or the closing of consumer markets to our exports. In the 21st century Brazil can’t get off the world”.

Especially as, according to the UN’s Food and Agriculture Organisation (FAO), in the next decade Brazil is expected to become the world’s biggest agricultural producer and food exporter, unless the reckless destruction of its natural resources prevents this.

Leaving the Paris Agreement, however, seems to be part of the anti-global mindset which predominates among Bolsonaro and his followers, very much influenced by the Steve Bannon playbook.

The president-elect has just announced the choice of an ultra-conservative diplomat to become Brazil’s new foreign minister. The new minister, Ernesto Araujo, sees globalisation as a Marxist plot, and wants Brazil, notable for its leadership of developing countries during previous governments and its active role in international organisations, to ally itself uncritically with the US, because “Donald Trump will save the Western world for Christianity.”

Partial retreat

However, under pressure from exporters, Bolsonaro has been forced to back down and maintain the Ministry of the Environment, although he is determined to weaken its monitoring and enforcement functions, and to water down environmental licensing laws.

He has also said that too much land in the Amazon is occupied by indigenous peoples and conservation units, and wants to open up these areas to economic exploitation. SAD figures show that while private properties account for the most deforested areas (58%), and even conservation units make up 24%, indigenous territories account for only 4% of the total. In other words, they are a barrier against deforestation.

Besides the ex-ministers, scientists and environmentalists have warned that if the president-elect carries out his promises, deforestation in the Amazon could explode. A group of researchers at INPE have used mathematical modelling to simulate possible changes in land use and calculated an increase of 268% in deforestation, rising from 6.9m km² in 2017 to 25.6m km² from 2020.

New risk

There is an added danger from another source, if individual Amazon states decide to invoke a clause in the Forest Code, which allows them to authorise a reduction in the 80% of land compulsorily set aside for conservation on private properties. A new study concludes that because of this potential reduction, “up to 15 million hectares of the Brazilian Amazon is at risk of losing its legal protection.”

Researchers at Chalmers University of Technology and KTH Royal Institute of Technology in Sweden, and the University of São Paulo (in Portuguese) say this is equivalent to more than 4 times the entire forest area of the UK. As most of the newly elected state governors and members of state legislatures have declared support for Bolsonaro, the probability that they will enact the clause, leading to more deforestation, is high.

Unfortunately, many of them choose to ignore the warnings of scientists like Paulo Moutinho of the Amazon Environmental Research Institute (IPAM) who said that “one of the ways to value this great forest is to recognise it as a great irrigation system . . . we can say that the food that is produced in Brazil, not only now but in the future, depends on this gigantic irrigation system which is the standing forest.” − Climate News Network

Landslides are growing risk to poorest

Waterlogged hillsides are dangerous. For those who live on them, or further downhill, they can be deadly. The global risk from landslides is rising.

LONDON, 3 September, 2018 – Lethal landslides are on the increase. Between 2004 and 2016, sudden cascades of rock, rubble and mud have claimed at least 50,000 lives. And fatal slips down unstable hillside slopes have steadily increased this century, according to new research.

British geographers report in the journal Natural Hazards and Earth System Sciences that they had amassed a database of 4,800 fatal landslides since 2004 and found that at least 700 of them had what they call a direct human fingerprint: they happened because people built on unstable soils, they mined, legally and illegally, they cut into hillsides, and they allowed pipes to leak.

In addition, heavy rainfall, earthquakes, explosions, dam collapses and freezing and thawing also set the earth moving at ever greater speeds, with deadly consequences.

The researchers also report that they found that other catalogues of natural disaster consistently under-estimated the toll exacted by landslides.

“It was surprising to find clear trends within the database that fatal landslides … were increasing globally during the period of 2004 to 2016”

One study found that the International Disaster Database, maintained by the international disaster community, under-estimated the number of fatal landslides by between 1400% and 2000%, often because the death tolls from such events were lumped in with other forms of disaster that might precipitate landslip: among them volcanic eruption, earthquake and flooding.

“We were aware that humans are placing increasing pressure on their local environment, but it was surprising to find clear trends within the database that fatal landslides triggered by construction, illegal hill-cutting and illegal mining were increasing globally during the period of 2004 to 2016,” said Melanie Froude, of the University of Sheffield, who led the study.

All the countries in the premier league for fatal landslides were in Asia: one in five of these happened in India, but Pakistan, Myanmar and the Philippines also suffered increasing losses.

Poorest in the shadows

Such findings are no surprise. First, there are more people on the planet, looking for new places to live and new ways of making a living, and the poorest are always more likely to be forced to the margins, to live on or in the shadow of dangerous, unstable slopes.

Second, the world is warming: for every extra degree Celsius the moisture-holding capacity of the atmosphere increases by about 7%, so more rain is likely to fall with ever greater intensity to saturate more soil and dislodge more rock. The researchers found that 79% of all landslides could be linked to rainfall.

And, with greater warming, there is a greater hazard of devastating superstorms, along with hurricanes and tropical cyclones that deliver the conditions for catastrophic floods not just in Asia but in Europe and the US.

Paradoxically, extremes of heat and drought can also create dangerous slopes: dangerous wild fires can remove the tree cover that stops hillsides from slipping, and drive people from their homes to places that could later be just as hazardous.

Applying knowledge

Research like this is never just academic: the point of such studies is to draw attention to natural disasters that need never have happened, and identify the communities most at risk.

And these, the scientists say, are more frequently in poor countries, with the poorest of all disproportionately at risk. The point the scientists make is that there is nothing inevitable about a “natural” disaster. Human error, heedlessness and ignorance all contribute to loss, suffering and death.

“With appropriate regulation to guide engineering design, education and enforcement by regulation by specialist inspectors, landslides triggered by construction, mining and hill-cutting are entirely preventable,” Dr Froude said. – Climate News Network

Tax havens threaten oceans and rainforests

Most of the foreign money funding ocean plunder and the felling of the Amazon forest comes through tax havens, researchers say.

LONDON, 14 August, 2018 – Tax havens have provided more than two-thirds of the foreign capital known to be linked to Amazon deforestation and pirate fishing, a new study says.

The researchers say 70% of known vessels involved in illegal, unreported and unregulated (IUU) fishing are or have been flagged under a tax haven jurisdiction. On average, they report, 68% of all investigated foreign capital (US$18.4bn of a total $26.9bn) which went to sectors associated with Amazon  deforestation between 2000 and 2011 was transferred through tax havens.

The report is the work of a team of researchers from the Stockholm Resilience Centre (SRC) and the Global Economic Dynamics and the Biosphere programme (GEDB), who say it is the first study to show how tax havens are linked to economic sectors with the potential to cause serious global environmental damage.

They say the release of the Paradise Papers and Panama Papers exposed how multinationals, politicians and the rich use offshore tax havens to conceal their wealth and money flows, and to reduce their exposure to tax. Accepting that the term “tax haven” is contested, their report uses a definition proposed in a report prepared for the US Congress.

The study’s lead author, Victor Galaz, deputy director of the SRC, says: “Our analysis shows that the use of tax havens is not only a socio-political and economic challenge, but also an environmental one. While the use of tax haven jurisdictions is not illegal in itself, financial secrecy hampers the ability to analyse how financial flows affect economic activities on the ground, and their environmental impacts.”

The study, published in the journal Nature Ecology and Evolution, is part of an on-going research project, Earth System Finance: New perspectives on financial markets and sustainability, led by GEDB and the Stockholm Resilience Centre in collaboration with Future Earth.

Systematic approach

The researchers say most previous analyses of the environmental impacts of tax havens are the work of investigative journalists focusing on a few locations. The new study, in contrast, takes a more systematic approach to analyse how the havens influence the sustainability of the ocean and the Amazon rainforest, two examples of the global environmental commons.

The Amazon forest is critical for stabilising the Earth’s climate system, and the oceans provide protein and income for millions of people worldwide, particularly in low-income food-deficit countries.

“The absence of a more systemic view is not surprising considering the chronic lack of data resulting from the financial opaqueness created by the use of these jurisdictions,” says co-author Beatrice Crona, GEDB’s executive director.

The study says lack of transparency hides how tax havens are linked to the degradation of environmental commons that are crucial for both people and planet at global scales.

“The use of tax havens is not only a socio-political and economic challenge, but also an environmental one”

It includes the first calculation of the foreign capital that flows into the beef and soya sectors operating in the Brazilian Amazon, both linked to deforestation.

The Cayman Islands proved to be the largest governmental source of transfers for foreign capital to both sectors. Well-known as a tax haven, the Islands provide three benefits to investors: legal efficiency, tax minimisation, and secrecy.

The study also includes a systematic analysis of tax havens’ role in global IUU fishing. With 70% of the vessels found to carry out or support IUU fishing, and for which flag information is available, flagged under a tax haven jurisdiction now or in the past, Belize and Panama are frequently mentioned.

Many of these tax havens are also so-called flags of convenience states, countries with limited monitoring and enforcement capacity that do not penalise vessels sailing under their flag even if they are identified as operating in violation of international law.

Dual identities

This combination of tax havens and flags of convenience allows companies to operate fishing vessels with dual identities, one used for legal and the other for illegal fishing.

“The global nature of fisheries value chains, complex ownership structures and limited governance capacities of many coastal nations, make the sector susceptible to the use of tax havens,” says co-author Henrik Österblom, SRC  deputy science director.

Among issues which the researchers suggest should be central to future research and to the governance of tax havens is the loss of tax revenue the havens cause. This, they argue, should be seen as an indirect subsidy to economic activities which damage the global commons, and organisations like UN Environment should assess the environmental costs involved.

And they argue that the international community should view tax evasion and aggressive tax planning as not only a socio-political problem, but also an environmental one. Putting tax havens on the global sustainability agenda, they say, is key to protecting the environment and achieving the UN Sustainable Development Goals. – Climate News Network

British app traps Peru’s illegal goldminers

A smartphone app devised by a British campaign group has brought to justice illegal goldminers in Peru, and is also being tested in African forests.

LONDON, 3 July, 2018 – An indigenous community in the Peruvian Amazon has helped to catch illegal goldminers red-handed using a smartphone app developed by a London-based environmental group, the Rainforest Foundation UK (RFUK).

The app employs smartphones linked to satellites, and by involving communities in monitoring provides a tool which connects local people with national law enforcement, in an attempt to stop deforestation.

Rachel Agnew, the Foundation’s head of communications, says: “The beauty of it is that it’s adaptable to a wide range of contexts. The tech actually evolved from a large mapping project when we discovered that it was possible to transmit small pockets of data from remote parts of the forest, via satellite, in real time.”

Using RFUK’s specially designed ForestLink system,  remote communities can send alerts and evidence of threats to the forest, including illegal mining and oil spills, to law enforcement agencies, even from areas with no mobile or internet connectivity.

“Local people . . . are on the frontlines of the fight against deforestation”

The forest group involved in the miners’ detention, the Masenawa community in Peru’s Madre de Dios region, has been working with RFUK and another local organisation, Federación Nativa del Rio Madre de Dios y Afluentes  (Fenamad), since 2016 to monitor illegal activity, using ForestLink.

The miners were caught in June just a few kilometres from the Amarakaeri Communal Reserve. They had set up a temporary camp as they searched for gold using heavy machinery, which attracted the attention of the Masenawa, who were on a monitoring mission.

Using a satellite uplink-fitted smartphone, the monitors promptly sent evidence of the mining to Fenamad, which reported it to the Peruvian authorities. The government’s environmental police force then intervened, destroying the miners’ machines, vehicles and other equipment in a series of controlled explosions. Five suspects were detained, and charges are now pending.

“Communities are the natural guardians of the Amazon. Technologies like ForestLink are helping indigenous peoples to protect the rainforest from illegal mining, even in areas outside their titled lands,” explained Fenamad’s real-time monitoring coordinator, Rosa Baca, in a statement.

Threats and beatings

The president of the Masenawa community, Carmen Irey Cameno, is a vocal opponent of goldmining. Since denouncing the illegal activity several members of the community have been threatened and two members of Cameno’s own family have been beaten up in retaliation.

“It’s alarming to see environmental defenders threatened and intimidated in this way”, said RFUK’s Peru and Andean Amazon coordinator, Aldo Soto. “At the same time, the determination of Carmen and her people in protecting their environment is truly inspiring.

“What this intervention shows is the power of harnessing technology for social good and putting it in the hands of local people, who are on the frontlines of the fight against deforestation.”

Madre de Dios is considered the capital of biodiversity in Peru, home to several natural reserves as well as the Manu National Park. In recent years illegal goldmining has become one of the leading drivers of deforestation in the region.

Grave threat

Goldmining, whether legal or not, has also become one of the most serious environmental and human rights problems across Peru, with an estimated US$15 billion-worth produced illegally between 2003 and 2014.

Research elsewhere in Latin America, published in 2017, has shown that when the price of gold rises, deforestation increases, while a price drop reduces the threat to the trees. Other researchers have found evidence showing a link between metals mined in Peru and Colombia and smelters in the European Union.

By 2015, there were an estimated 30,000 artisanal goldminers (all of whom needed a permit, RFUK says) operating in Madre de Dios alone.

The RFUK Real-Time Monitoring project is in use not only in Peru, but also in three African states: Ghana, Cameroon and the Democratic Republic of Congo (DRC).

In one of the most recent reprisal attacks on environmental protection groups reported worldwide, five wildlife rangers and a driver involved in safeguarding the gorillas of the Virunga national park in the DRC were killed in an ambush in April 2018. More than 170 rangers have been killed in the park while protecting animals in the last 20 years. – Climate News Network

A smartphone app devised by a British campaign group has brought to justice illegal goldminers in Peru, and is also being tested in African forests.

LONDON, 3 July, 2018 – An indigenous community in the Peruvian Amazon has helped to catch illegal goldminers red-handed using a smartphone app developed by a London-based environmental group, the Rainforest Foundation UK (RFUK).

The app employs smartphones linked to satellites, and by involving communities in monitoring provides a tool which connects local people with national law enforcement, in an attempt to stop deforestation.

Rachel Agnew, the Foundation’s head of communications, says: “The beauty of it is that it’s adaptable to a wide range of contexts. The tech actually evolved from a large mapping project when we discovered that it was possible to transmit small pockets of data from remote parts of the forest, via satellite, in real time.”

Using RFUK’s specially designed ForestLink system,  remote communities can send alerts and evidence of threats to the forest, including illegal mining and oil spills, to law enforcement agencies, even from areas with no mobile or internet connectivity.

“Local people . . . are on the frontlines of the fight against deforestation”

The forest group involved in the miners’ detention, the Masenawa community in Peru’s Madre de Dios region, has been working with RFUK and another local organisation, Federación Nativa del Rio Madre de Dios y Afluentes  (Fenamad), since 2016 to monitor illegal activity, using ForestLink.

The miners were caught in June just a few kilometres from the Amarakaeri Communal Reserve. They had set up a temporary camp as they searched for gold using heavy machinery, which attracted the attention of the Masenawa, who were on a monitoring mission.

Using a satellite uplink-fitted smartphone, the monitors promptly sent evidence of the mining to Fenamad, which reported it to the Peruvian authorities. The government’s environmental police force then intervened, destroying the miners’ machines, vehicles and other equipment in a series of controlled explosions. Five suspects were detained, and charges are now pending.

“Communities are the natural guardians of the Amazon. Technologies like ForestLink are helping indigenous peoples to protect the rainforest from illegal mining, even in areas outside their titled lands,” explained Fenamad’s real-time monitoring coordinator, Rosa Baca, in a statement.

Threats and beatings

The president of the Masenawa community, Carmen Irey Cameno, is a vocal opponent of goldmining. Since denouncing the illegal activity several members of the community have been threatened and two members of Cameno’s own family have been beaten up in retaliation.

“It’s alarming to see environmental defenders threatened and intimidated in this way”, said RFUK’s Peru and Andean Amazon coordinator, Aldo Soto. “At the same time, the determination of Carmen and her people in protecting their environment is truly inspiring.

“What this intervention shows is the power of harnessing technology for social good and putting it in the hands of local people, who are on the frontlines of the fight against deforestation.”

Madre de Dios is considered the capital of biodiversity in Peru, home to several natural reserves as well as the Manu National Park. In recent years illegal goldmining has become one of the leading drivers of deforestation in the region.

Company averts climate chocolate threat


Fears that the supply of cocoa beans would dry up have led a confectionery giant to help farmers avert a climate chocolate threat.

LONDON, 20 April, 2018 – If you have a sweet tooth, a liking not only for sugar-rich sweets but especially for chocolate, you’ve cause for celebration: the prospect of a climate chocolate threat is a little less likely.

Keeping the world supplied with chocolate is becoming more difficult as deforestation and climate change make it harder for farmers in the tropics to grow the trees that produce the cocoa beans.

Paying producers more for beans under the banner of Fairtrade certainly improved the lot of poor farmers, most of them small-scale cultivators, but that did not solve the long-term problem of providing enough cocoa to supply the huge world market.

The cocoa tree’s natural habitat is the lower storey of the evergreen rainforest, but cocoa farmers do not always grow their trees in the best conditions.
The trees only thrive 10 degrees either side of the Equator, where they need sufficient warmth, rainfall, soil fertility and drainage if they are to flourish.

Clearing rainforest to make space for cocoa tree plantations is some farmers’ preferred practice, but it is not a sustainable way to maintain production.

“We pioneered Cocoa Life to address cocoa farm productivity alongside community development. We strive to not only empower cocoa farmers but also to help their communities thrive”

But, fearing that the supply of cocoa beans was in jeopardy and the price of their raw material would affect production, one of the world’s largest manufacturers is now to invest US$400m by 2022 to help 200,000 cocoa farmers secure a long-term future.

The scheme, called Cocoa Life, is helping farmers in six key cocoa-growing countries: Ghana, Côte d’Ivoire, Indonesia, India, the Dominican Republic and Brazil.

The company responsible, Mondelēz International, which owns brands like Cadbury, Suchard and Milka, believes many cocoa-growing regions could be wiped out unless action is taken.

Cathy Pieters, director of the Cocoa Life programme at Mondelēz, told the Climate News Network: “The challenges in cocoa are becoming more diverse and complex. In fact, some reports show current cocoa-producing regions may no longer be suitable for cocoa production in the next 30 years if we don’t take action.

Expecting change

“Our approach to climate change is deliberate because we expect a change to happen – a transformation. As one of the largest chocolate makers in the world, we are mobilising farmers and their communities to prioritise forest protection.”

Key to the programme is educating farmers, helping women by providing finance and stopping child labour, and also improving the environment. The company is helping farmers prevent further destruction of rainforest and planting trees around cocoa farms to protect them and recreate the habitat in which trees are most productive.

In this way farmers are producing far more cocoa beans from the same area of land. This year the programme has planted more than a million trees to restore the forest canopy.

Cocoa Life was launched in 2012 and to the end of last year had trained more than 68,000 members of the cocoa-farming community in best practice to ensure a sustainable industry. Cocoa saplings and shade trees needed to replicate rainforest conditions had been distributed to 9,600 farmers.

Industry example

The company says that by the end of 2017 it had increased the amount of its cocoa from sustainable sources by 14 percentage points to 35% and reached 120,000 farmers, 31% more than in 2016.

The potential crisis in the cocoa-growing industry and the threat of climate change have led other manufacturers to embark on similar schemes, and 11 companies have now joined together in a World Cocoa Foundation alliance to protect rainforest from further destruction by cocoa farmers looking for new land.

Although Mondelēz is protecting its own interests by ensuring its cocoa supply chain, Cathy Pieters is clear that the programme is much more than that alone: “We pioneered Cocoa Life to address cocoa farm productivity alongside community development. We strive to not only empower cocoa farmers but also to help their communities thrive.

“We help them find real solutions like diversifying their income beyond the farm, which in turn develops their capacity to stand strongly on their own feet. I believe when we involve farmers as part of the solution, we see lasting, positive change happen.” – Climate News Network

Loss of unregarded forests is at danger level

Three new studies highlight the value of the world’s unregarded forests – and the dangers they face as the climate changes.

LONDON, 19 March, 2018 – The world’s unregarded forests are at risk. Intact forest is now being destroyed at an annual rate  that threatens to cancel out any attempts to contain global warming by controlling greenhouse gas emissions.

Trees in the tropical regions are dying twice as fast as they did 35 years ago – and human-induced climate change is a factor.

And a third study has highlighted the value to humanity of intact forests, while estimating that four-fifths of the Earth’s remaining woodlands are now in some way degraded by human activities. “This figure,” researchers warn, “is probably an underestimate.”

All three studies confirm the value of forests to the planet – and underline the increasingly dangerous rate of loss.

An international team of researchers report in Nature Communications that they made a computer model of the planet’s atmospheric conditions: they included natural and human-triggered aerosols, volatile organic compounds, greenhouse gases and other factors that influence temperature, one of which is albedo: the scientist’s word for the capacity of terrain to absorb or reflect solar radiation.

Cooling effect

They tested their model against the Earth’s temperature records since 1850 – and then ran it again, this time with a hypothetical forest-free world.

“The result was a significant rise of 0.8°C in mean temperature. In other words, today the planet would be almost 1°C warmer on average if there were no more forests,” said Paulo Artaxo, of the University of São Paulo in Brazil.

“If we go on destroying forests at the current pace – some 7,000 square kilometres per year in the case of Amazonia – in three to four decades, we’ll have a massive accumulated loss. This will intensify global warming regardless of all efforts to reduce greenhouse gas emissions.”

The second study, in the journal New Phytologist, is a reminder of just how complex the challenge of forest conservation can be. Foresters and botanists from around the planet concentrated on the special case of the tropical rainforest, home to so much of the world’s terrestrial biodiversity, and analysed the hazards.

“Earth’s remaining forests are the crown jewels, ones that global climate and biodiversity policies must now emphasise”

These include rising temperatures, increasing carbon dioxide levels, fires, more destructive storms, insect infestation and the impact of woody vines known as lianas.

They found that trees in some areas were dying at about twice the rate they were 35 years ago.

“No matter how you look at it, trees in the moist tropics wil l likely die at elevated rates through the end of the century relative to their mortality rates in the past,” said Nate McDowell, of the US government’s Pacific Northwest National Laboratory.

“There is a host of factors that appear to be driving mortality, and the likelihood of those factors occurring is increasing.”

Such studies deliver no great surprises: they add levels of detail to a big picture that has been clearly outlined and repeatedly confirmed. Humans do not need to fell forests to find new farmland, and when they do so they damage the natural diversity on which they and other creatures depend.

Winners all round

Healthy forests absorb carbon dioxide from human fossil fuel combustion and at the same time reduce regional temperatures.

Forests are being destroyed at a disconcerting rate, but if humans conserved them, there would be a greater chance of containing global warming to targets set by a global climate summit in Paris in 2015.

And repeated studies have confirmed that conserved forests deliver many benefits.  Everybody wins.

Just how humans benefit has been spelled out yet again in the journal Nature Ecology and Evolution. Forests cover about 25% of the planet’s land surface, but over the past three centuries Earth has lost at least a third of its natural tree cover, due to human expansion. More than 80% of what remains has been affected by human action.

Vital stabilisers

But these same forests absorb around 25% of carbon emissions from factory chimneys, power stations and car exhausts; they play a vital role in stabilising local and regional weather, and they reduce the risk of drought.

Intact forests are home to higher numbers of other species; they sustain many indigenous cultures; their conservation delivers medically-beneficial plants and their degradation drives the spread of infectious diseases.

“It is well-known that forest protection is essential for any environmental solution – yet not all forests are equal,” said James Watson, of the University of Queensland in Australia and the World Conservation Society.

“Forest conservation must be prioritised based on their relative values, and Earth’s remaining forests are the crown jewels, ones that global climate and biodiversity policies must now emphasise.” – Climate News Network
