New map shows way to reducing roads’ destruction of nature

European, Brazilian and US scientists have delivered a new map of humanity’s mark on the world.

Roads now fragment the terrestrial landscape and divide it into 600,000 significant patches – and only 7% of the roadless areas are larger than 100 square kilometres.

More than half of the patches are less than 1 sq km and four-fifths are less than 5 sq km. The implication is that humans are getting everywhere, and bringing with them noise, pollution, damage to wildlife and biological invaders.

About the only regions in which roads are few are the tundra, the deserts and the rock- and ice-covered highlands. The temperate and mixed forests of the world are the most divided by roads.

Pierre Ibisch, of Eberswalde University for Sustainable Development in Germany, and colleagues report in Science that they used citizen science and internet datasets, and reviewed 282 studies, to make the maps.

They allowed a 1km buffer zone along each road, because the construction of any road creates disturbance, including the loss of timber. And they conclude that a third of the world’s roads are now in regions with low biodiversity, low ecological function and low ecosystem resilience.

They see those areas still beyond the reach of cars, trucks and tractors as vulnerable: “Global protection of ecologically valuable roadless areas is inadequate”, they write. “International recognition and protection of roadless areas is urgently needed to halt their continued loss.”

Construction of roads

Such studies are fresh ways of illustrating what scientists call the ‘Great Acceleration‘: one human lifetime ago, the world was home to only 2.5bn people, and very few of them had cars.

UN scientists predict a population of at least 9bn people this century, and possibly a much higher number before 2100. The cities are expanding, and new built-up areas will cover more than 1 million sq km between now and 2040.

By 2050, the world will build an estimated 25 million kilometres of new road lanes, most of them in the developing world. In a related finding, another team of researchers has just calculated that the human ‘technosphere’ – the sum of all things humans have built or excavated – has reached a mass of 30 trillion metric tons.

Andrew Balmford, a professor of conservation science at the University of Cambridge in the UK, and colleagues argue in a separate study in the Public Library of Science journal Biology that it should be possible to devise a highway strategy that makes the best use of existing farmland, serves the greatest number of people and yet conserves the natural ecosystems that deliver services of profound value to all humanity.

Among these are water management, carbon storage, crop pollination, and plants and animals that could be the source of new foods and medicines.

We must safeguard the most important areas!

The researchers tested their argument in the Greater Mekong region of south-east Asia, a landscape that includes Vietnam, Laos, Cambodia and some of Myanmar. It is home to 320 million people, 20,000 plant species, 2,000 terrestrial vertebrate species and 850 varieties of freshwater fish, and it has lost a third of its tropical forest in the past four decades.

“The Mekong region is home to some of the world’s most valuable tropical forests. It’s also a region in which a lot of roads are going to be built, and blanket opposition by the conservation community is unlikely to stop this”, says co-author Xu Jianchu, professor of ethnoecology at the Kunming Institute of Botany in China and regional coordinator for the World Agroforestry Centre.

“Studies like ours help pinpoint the projects we should oppose most loudly, while transparently showing the reasons why and providing alternatives where environmental costs are lower and development benefits are greater. Conservationists need to be active voices in infrastructure development.”

According to environmental group Roadfree, which campaigns to prevent the fragmentation of forests by roads worldwide, “The international community is engaged in a race to halt biodiversity loss and reduce carbon emissions caused by deforestation. Funding for environmental protection is currently scarce; yet keeping wild areas free of roads is a remarkably cost-efficient way of protecting biodiversity and keeping the planet cool, and is an antidote to slow political decision making.

“These maps are a crucial tool to help decision-makers rethink road building, and with us, promote more sustainable options and better infrastructure planning.”

Lord Smith’s conflict of interest: why we cannot trust the ASA on fracking!

Having run many environmental campaigns over many years I know very well the importance of getting the facts right.

With that basic principle in mind I was surprised to hear a radio broadcast on January 4th suggesting that in relation to its campaign against fracking for shale gas and shale oil, that Friends of the Earth had got some basic points wrong.

The allegation was that a leaflet explaining some of the health and pollution risks of fracking had made factual errors.

I spoke to Craig Bennett, Chief Executive at Friends of the Earth, to find out what had happened. I used to do his job some years ago and was very interested to know what the campaigners had to say.

I quickly discovered that reality differed somewhat from the headlines that screamed about Friends of the Earth’s alleged errors.

As it happens, the campaign group hadn’t got anything wrong and the reason that the radio broadcast, and a number of newspaper articles appearing around the same time, said otherwise was down to that impression being created by a public body with a remit to independently adjudicate the veracity of claims made by companies and charities.

Has the ASA itself been politicised?

The public body in question is the Advertising Standards Authority (ASA), and it looks very much as if, on fracking, it has been engaged in political activities itself. The chronology of events went like this …

During December the ASA assured Friends of the Earth in writing that they were planning to make an informal resolution on complaints they had received about claims made on fracking. They said that at that point the ASA “will not give details of the complaint or state that you breached the Code.” Since Friends of the Earth’s claims had not been ruled to be false, the ASA should not of course say that it had breached its code.

The ASA had by then closed their case on the Friends of the Earth leaflet without a ruling as ‘informally resolved‘ – because no final decision had been made by the ASA Council on the statements, or their accuracy. As Craig Bennett explains:

“Friends of the Earth agreed not to reuse an old leaflet, or repeat some specific wording, because the case was taking time away from vital campaigning – we are, after all, talking about an out-of-date leaflet from two years ago which we weren’t using anyway. But, one thing is certain, we continue to stand by our facts. Indeed, the scientific evidence against fracking is stronger than ever.”

Having established that the case would be closed with no ruling, the ASA went on to say that “The ASA publishes basic details of the complaints it investigates on its website, www.asa.org.uk. Your company name, the industry sector and the medium in which the advertising appeared will be published on Wednesday 28 December in a list with other advertisers that have co-operated in resolving complaints. It will not give details of the complaint or state that you breached the Code.”

A carefully timed media coup by the ASA?

It was in other words to be a non-story. There was no ruling that Friends of the Earth had made errors. Outline information only, with “no details”, was to be published alongside a number of other cases with no statement that the code had been breached.

During the Christmas holidays, however, the campaign group was told that the ASA had decided to move the publication date to Wednesday 4th January – as it happens the day before fracking company Cuadrilla moved onto a site in Lancashire where they are now preparing to try to frack.

Then on Tuesday 3rd January Friends of the Earth started getting press enquires, asking whether the group had admitted to being wrong about health, water and property price claims in its leaflet. A BBC journalist forwarded an extract of what they said was an ASA press release.

This was especially strange as the ASA said they hadn’t put out a press release, yet what the BBC shared, and what I saw, looked very much like one. A flurry of publicity followed, including that piece I heard on the radio on January 4th.

The effect was to create a media blitz that drowned out any campaigning by anti-fracking activists that might have been broadcast that morning to accompany Cuadrilla’s first day of operations on its new site in Lancashire.

The compromised chairman of the ASA – fracking ‘task force’ supremo Chris Smith!

As if this wasn’t fishy enough, I discovered a major conflict of interest at the ASA. The Chairman of the ASA is none other than Lord Chris Smith – who is also the chair of the industry funded Task Force on Shale Gas. This is a remarkable and clear conflict of interest and makes the facts of what happened in relation to the Friends of the Earth case all the more fascinating.

The conflict deepens when one realizes how the Task Force was evidently influential in helping the ASA form its initial views in relation to the Friends of the Earth case.

While the ASA evidently ignored, or at least failed to appreciate, the strong scientific and technical backing to the Friends of the Earth claims (many of which were supported by experts) the ASA quoted an industry source in defence of their broad view that the campaigners had got it wrong. That source? Yes – none other than Chris Smith’s Task Force on Shale Gas!

And so it was that Cuadrilla, the UK’s largest fracking company, gained helpful air cover at a crucial moment – cover derived from an ASA intervention coming in part from misleading information from a pro-fracking body. A body chaired by the same man who chairs the ASA. All a coincidence?

Scandal and intrigue

While you ponder that question, have a look at some of the claims that Friends of the Earth didn’t get wrong. These were the ones that caused such a furore, and as you hear more from that Task Force and Cuadrilla in the months ahead, you might like to bear these in mind.

  • “Fracking involves pumping millions of litres of water containing a toxic cocktail of chemicals deep underground … Up to 80% never returns to the surface and could end up in your drinking water.”
  • “A hospital near a US fracking site reports asthma rates three times higher than average.”
  • “25% of fracking chemicals could cause cancer. Also, more than 75% of fracking chemicals could affect your skin, eyes and respiratory system. Whilst 50% could affect your nervous, immune and cardiovascular systems.”

Now, astonishingly in my opinion, the chief executive of the ASA, Guy Parker, has personally stepped into the fray with an ‘opinion piece‘ published on the ASA website, in which he succeeds only in digging his organisation even deeper into a hole of its own making. He writes:

“We told Friends of the Earth that based on the evidence we’d seen, specific claims it made in its anti-fracking leaflet about the effects of fracking on the health of local populations, drinking water or property prices, or claims with the same meaning, cannot be repeated.”

Trouble is, insists Craig Bennett, that statement is “factually wrong”. All the claims are true and based on solid evidence. Friends of the Earth was never told to avoid repeating those claims, says Craig. Instead it volunteered to avoid them to put a swift end to the dispute. “There is so much new evidence on fracking now with even more up to date and persuasive information, and that’s where we wanted to focus our campaigning!”

The real questions here – all scrupulously avoided by Guy Parker in his ‘opinion piece’ – concern the extraordinary conflict of interest of the ASA’s own chairman, Lord Smith; the ASA’s uncritical acceptance of his industry-biased evidence; and the ASA’s unprecedented use of the case to attack one of the UK’s leading anti-fracking campaign groups at this critical time; and to do so in breach of its promise to “not give details of the complaint or state that you breached the Code.”

Reassured by the independence of the ASA and its ability to act in the public interest? I’m not.

This was especially strange as the ASA said they hadn’t put out a press release, yet what the BBC shared, and what I saw, looked very much like one. A flurry of publicity followed, including that piece I heard on the radio on January 4th.

The effect was to create a media blitz that drowned out any campaigning by anti-fracking activists that might have been broadcast that morning to accompany Cuadrilla’s first day of operations on its new site in Lancashire.

The compromised chairman of the ASA – fracking ‘task force’ supremo Chris Smith!

As if this wasn’t fishy enough, I discovered a major conflict of interest at the ASA. The Chairman of the ASA is none other than Lord Chris Smith – who is also the chair of the industry funded Task Force on Shale Gas. This is a remarkable and clear conflict of interest and makes the facts of what happened in relation to the Friends of the Earth case all the more fascinating.

The conflict deepens when one realizes how the Task Force was evidently influential in helping the ASA form its initial views in relation to the Friends of the Earth case.

While the ASA evidently ignored, or at least failed to appreciate, the strong scientific and technical backing to the Friends of the Earth claims (many of which were supported by experts) the ASA quoted an industry source in defence of their broad view that the campaigners had got it wrong. That source? Yes – none other than Chris Smith’s Task Force on Shale Gas!

And so it was that Cuadrilla, the UK’s largest fracking company, gained helpful air cover at a crucial moment – cover derived from an ASA intervention coming in part from misleading information from a pro-fracking body. A body chaired by the same man who chairs the ASA. All a coincidence?

Scandal and intrigue

While you ponder that question, have a look at some of the claims that Friends of the Earth didn’t get wrong. These were the ones that caused such a furore, and as you hear more from that Task Force and Cuadrilla in the months ahead, you might like to bear these in mind.

  • “Fracking involves pumping millions of litres of water containing a toxic cocktail of chemicals deep underground … Up to 80% never returns to the surface and could end up in your drinking water.”
  • “A hospital near a US fracking site reports asthma rates three times higher than average.”
  • “25% of fracking chemicals could cause cancer. Also, more than 75% of fracking chemicals could affect your skin, eyes and respiratory system. Whilst 50% could affect your nervous, immune and cardiovascular systems.”

Now, astonishingly in my opinion, the chief executive of the ASA, Guy Parker, has personally stepped into the fray with an ‘opinion piece‘ published on the ASA website, in which he succeeds only in digging his organisation even deeper into a hole of its own making. He writes:

“We told Friends of the Earth that based on the evidence we’d seen, specific claims it made in its anti-fracking leaflet about the effects of fracking on the health of local populations, drinking water or property prices, or claims with the same meaning, cannot be repeated.”

Trouble is, insists Craig Bennett, that statement is “factually wrong”. All the claims are true and based on solid evidence. Friends of the Earth was never told to avoid repeating those claims, says Craig. Instead it volunteered to avoid them to put a swift end to the dispute. “There is so much new evidence on fracking now with even more up to date and persuasive information, and that’s where we wanted to focus our campaigning!”

The real questions here – all scrupulously avoided by Guy Parker in his ‘opinion piece’ – concern the extraordinary conflict of interest of the ASA’s own chairman, Lord Smith; the ASA’s uncritical acceptance of his industry-biased evidence; and the ASA’s unprecedented use of the case to attack one of the UK’s leading anti-fracking campaign groups at this critical time; and to do so in breach of its promise to “not give details of the complaint or state that you breached the Code.”

Reassured by the independence of the ASA and its ability to act in the public interest? I’m not.

New map shows way to reducing roads’ destruction of nature

European, Brazilian and US scientists have delivered a new map of humanity’s mark on the world.

Roads now fragment the terrestrial landscape and divide it into 600,000 significant patches – and only 7% of the roadless areas are larger than 100 square kilometres.

More than half of the patches are less than 1 sq km and four-fifths are less than 5 sq km. The implication is that humans are getting everywhere, and bringing with them noise, pollution, damage to wildlife and biological invaders.

About the only regions in which roads are few are the tundra, the deserts and the rock- and ice-covered highlands. The temperate and mixed forests of the world are the most divided by roads.

Pierre Ibisch, of Eberswalde University for Sustainable Development in Germany, and colleagues report in Science that they used citizen science and internet datasets, and reviewed 282 studies, to make the maps.

They allowed a 1km buffer zone along each road, because the construction of any road creates disturbance, including the loss of timber. And they conclude that a third of the world’s roads are now in regions with low biodiversity, low ecological function and low ecosystem resilience.

They see those areas still beyond the reach of cars, trucks and tractors as vulnerable: “Global protection of ecologically valuable roadless areas is inadequate”, they write. “International recognition and protection of roadless areas is urgently needed to halt their continued loss.”

Construction of roads

Such studies are fresh ways of illustrating what scientists call the ‘Great Acceleration‘: one human lifetime ago, the world was home to only 2.5bn people, and very few of them had cars.

UN scientists predict a population of at least 9bn people this century, and possibly a much higher number before 2100. The cities are expanding, and new built-up areas will cover more than 1 million sq km between now and 2040.

By 2050, the world will build an estimated 25 million kilometres of new road lanes, most of them in the developing world. In a related finding, another team of researchers has just calculated that the human ‘technosphere’ – the sum of all things humans have built or excavated – has reached a mass of 30 trillion metric tons.

Andrew Balmford, a professor of conservation science at the University of Cambridge in the UK, and colleagues argue in a separate study in the Public Library of Science journal Biology that it should be possible to devise a highway strategy that makes the best use of existing farmland, serves the greatest number of people and yet conserves the natural ecosystems that deliver services of profound value to all humanity.

Among these are water management, carbon storage, crop pollination, and plants and animals that could be the source of new foods and medicines.

We must safeguard the most important areas!

The researchers tested their argument in the Greater Mekong region of south-east Asia, a landscape that includes Vietnam, Laos, Cambodia and some of Myanmar. It is home to 320 million people, 20,000 plant species, 2,000 terrestrial vertebrate species and 850 varieties of freshwater fish, and it has lost a third of its tropical forest in the past four decades.

“The Mekong region is home to some of the world’s most valuable tropical forests. It’s also a region in which a lot of roads are going to be built, and blanket opposition by the conservation community is unlikely to stop this”, says co-author Xu Jianchu, professor of ethnoecology at the Kunming Institute of Botany in China and regional coordinator for the World Agroforestry Centre.

“Studies like ours help pinpoint the projects we should oppose most loudly, while transparently showing the reasons why and providing alternatives where environmental costs are lower and development benefits are greater. Conservationists need to be active voices in infrastructure development.”

According to environmental group Roadfree, which campaigns to prevent the fragmentation of forests by roads worldwide, “The international community is engaged in a race to halt biodiversity loss and reduce carbon emissions caused by deforestation. Funding for environmental protection is currently scarce; yet keeping wild areas free of roads is a remarkably cost-efficient way of protecting biodiversity and keeping the planet cool, and is an antidote to slow political decision making.

“These maps are a crucial tool to help decision-makers rethink road building, and with us, promote more sustainable options and better infrastructure planning.”

Every green pixel of the map is at least 10km from the nearest road. It shows very concretely Earth’s terrestrial areas free of roads including forests, polar regions and deserts.

The situation is particularly dramatic in forest areas where the spread of road networks has fragmented natural habitats, endangering intact ecosystems and forest dependant populations.

Cuckoos in the nest: clipping the wings of corporate capitalism

Many people feel that the capitalist economic system delivers wealth to a few and somehow cheats the rest of opportunity.

I agree: our market system is being looted by a small minority and the only real solutions call for courageous measures.

It has been all too easy for things to slide to excess. Traders in financial markets manipulate prices to obtain higher bonuses.

They and their managers take massive gambles with shareholders’ money because these are essentially one-way bets – governments and central banks will bail them out if things go awry.

The management teams of large companies reward themselves with larger and larger compensation packages virtually independent of the performance of their enterprises.

In a more subtle strategy, and without perhaps considering the effects, business leaders can end up looting the future by investing insufficiently for the longer term. They are playing a game skewed towards the pursuit of short-term profits in order to achieve higher personal payouts.

In industry we see increasing forms of cartel-like behaviour everywhere. The big banks offer essentially similar services on similar terms and extract monopoly rents, often in egregious forms such as massive charges for late payments or unauthorised overdrafts for retail clients.

Large pharma companies actively work to extend patent protection on drugs and to limit the ability of generic drug makers to compete effectively.

Underdone oversight

But how can all this happen when the institutions of the market system are supposed to prevent them?

Companies are overseen by boards of directors who represent the shareholders and determine management compensation. Investors control the capital base of enterprises and have the power to replace the boards of directors.

Market activity is undertaken within a framework of laws and regulations overseen by central banks and by regulatory agencies staffed by civil servants and, over them, sit the elected representatives of the people.

In theory, it should work flawlessly, but too often the structure fails, and it’s not all that hard to explain why.

Let’s start with publicly traded companies. Many are actually controlled by their management rather than by independent directors. In the US it is still common for the CEO to also be the chair of the board and so play a major role in choosing those supposed to provide oversight. In any case, we typically see the same people serve on multiple boards while the CEO of one company sits on the board of another. No wonder boards endorse egregious compensation schemes.

But shouldn’t the shareholders throw out all the rascals on the boards? If by a shareholder we mean someone with deep knowledge of a company and a commitment to enhance its long-term performance, then many large companies have no shareholders at all.

The investment logic of diversification and the rise of passive investing (where investors only track the performance of a share index like the S&P 500) drives individuals to spread holdings out on a global basis. Large investing institutions, often largely passive themselves, hold positions in too many enterprises to either understand or care about individual cases.

And a situation has emerged where a handful of giant funds own a large share of the total value of listed companies so that their executives become part of the same pattern of behaviour. The ultimate shareholders – pension plan holders like you and I – are often too busy, don’t care, or don’t understand.

Revolving door

Now let’s turn to the regulators. They have deep problems which we don’t like to acknowledge.

First, they struggle to hire talent which can match the companies they are regulating. The ambitious and clever graduate can choose US$100,000 a year at a Central Bank or US$1m at the investment bank of their choice. This is made worse by the revolving door problem. If you know that, in a few years time, you will be seeking a job at a bank, just how tough on them are you going to be now?

What of their political masters? Well, former politicians, ex-presidents and ex-prime Ministers perform the revolving door trick very well.

More important, it takes money to win elections. Who has the money to donate? The companies and their key executives. The US offers the extreme of this situation. And the more regulated an industry is, usually the more concentrated it is among a handful of companies, meaning the reward for influencing regulation are concentrated in the enterprises that can do the most harm.

The benign term for all this is ‘regulatory capture‘.

Fishy business

Enough said. As world leaders from business and politics prepare to meet at the World Economic Forum in Davos, what should be done?

Two cautions. Because the money and power in the system is controlled by the looters, every ameliorating action will be fought tooth and nail. And, there is no magic cure: the most we can aspire to is to make things incrementally, but materially better.

The fish stinks from the head so we should start there. We must dramatically curtail the role of money and patronage in politics. Only if this is done will it be feasible to rebuild the regulatory apparatus and break the cartels.

Now consider the comprehensive failure of corporate governance at large public companies. I suggest that the large public company has had its day. Public listing is not needed to raise essential capital, as was the case in its 19th and early 20th-century heyday. The stock markets today are for speculation, for games by competing algorithms and profit-taking for insiders.

We should discourage ‘public’ ownership in favour of private ownership and partnerships. Then, more people with the power to control will also have an incentive to think long term and to contain risk.

World’s biggest tropical carbon sink found in Congo rainforest

British scientists have just discovered one of the richest stores of carbon on Earth: 145,000 square kilometres of peatland – an area larger than England – in the forests of the central Congo basin.

The reservoir of compressed plant material holds at least 30 Gt (billion tonnes) of carbon. And this pristine and undisturbed sink of peat is the equivalent of about two decades of fossil fuel combustion in the United States.

The discovery, reported in the journal Nature, is significant for three reasons. One is that it adds a substantial new component to one of the most head-scratching problems in climate science: the arithmetic of the carbon cycle, a cycle vital both to all living things and to climate machinery.

The second is a reminder that, in a world combed by geographers and topographers, monitored for 30 years by dozens of orbiting satellites, and explored and exploited by more than 7 billion people, there is still scope for important discovery.

Third, if this carbon store is opened up to development, it could end up emitting a massive volume of CO2 with disastrous results for global climate. This is already happening in Indonesia, where huge areas of peatland swamp forest are being logged, drained, burnt and cleared for oil palm plantations, making the country the world’s fifth biggest carbon emitter.

‘The largest peatland complex in the tropics’

“Our research shows that the peat in the central Congo Basin covers a colossal amount of land. It is 16 times larger than the previous estimate and is the single largest peatland complex found anywhere in the tropics”, said Simon Lewis, a geographer at the University of Leeds, and one of the discoverers.

“We have also found 30 billion tonnes of carbon that nobody knew existed. The peat covers only 4% of the whole Congo Basin, but stores the same amount of carbon below ground as that stored above ground in the trees covering the other 96%.

“These peatlands hold nearly 30% of the world’s tropical peatland carbon, that’s about 20 years of the fossil fuel emissions of the United States of America.”

Working with Congolese colleagues, Professor Lewis and his co-author Greta Dargie discovered the peatlands in 2012, during a field trip to the swamps of the Cuvette Centrale at the heart of one of the world’s last remaining great forests in the Republic of the Congo.

They found a vast extent of dense peat around two metres in depth – and sometimes almost six metres – and used space-based instrument measurements to map an extent of 145,000 sq km.

Stores of buried peat should be no great surprise in the wetlands of a tropical rainforest: swamp water would prevent organic decay, and peat would build up, as it has for instance in the rainforests of Borneo. But the scale of this carbon sink is unprecedented.

Coal in formation

The carbon sink in the African peatlands is preserved plant material stored over huge periods of time. Plants photosynthesise tissue from carbon dioxide in the atmosphere; humans and animals and fungi consume the plants and return most of the carbon to the atmosphere.

A residue, however, is preserved in the soil, as semi-decayed wood or foliage, or on the seabed as the carbon shells and bones of sea creatures, and this difference between source and sink is what perplexes climate scientists

They need to know how to work out, in ever finer detail, the rate at which the world will warm as a consequence of two centuries of combustion of fossil fuels – because oil and coal and natural gas were also once living tissue, made by ancient photosynthesis.

So researchers have tried to assess the quantities of soil carbon stored as peat under the thawing Arctic permafrost, they have asked themselves questions about the impact of wildfires in the world’s forests, they have tried to complete the intricate arithmetic of the effect of climate change on how much carbon the forests can absorb, and on the overall impact of global warming on the world’s grasslands and savannahs.

And at every point, they have found new riddles to solve: are the oceans responding to climate change by gulping down more carbon? What role do fungi have in the uptake of carbon in the soil? And why are the world’s fjordlands so important as carbon reservoirs? So the Congo basin discovery adds a new dimension to the calculations.

Radiocarbon evidence suggests the carbon sink has been accumulating for the last 10,600 years, and the discovery increases the best estimate so far of tropical peatland by up to 36%.

Protection is urgent

Now, the next step is to find ways to protect the find, says Professor Lewis: “Peatlands are only a resource in the fight against climate change when left intact, and so maintaining large stores of carbon in undisturbed peatlands should be a priority.

Our new results show that carbon has been building up in the Congo Basin’s peat for nearly 11,000 years. If the Congo Basin peatland complex was to be destroyed, this would release billions of tonnes of carbon dioxide into our atmosphere.”

Dr Dargie added: “With so many of the world’s tropical peatlands under threat from land development, and the need to reduce carbon emissions to zero over the coming decades, it is essential that the Congo Basin peatlands remain intact.”
