Record fires are raging in Brazil’s Amazon rainforest, with more than 2,500 fires currently burning. They are collectively emitting huge amounts of carbon, with smoke plumes visible thousands of kilometres away.

Fires in Brazil increased by 85% in 2019, with more than half in the Amazon region, according to Brazil’s space agency.

This sudden increase is likely down to land degradation: land clearing and farming reduces the availability of water, warms the soil and intensifies drought, combining to make fires more frequent and more fierce.

1. Why the Amazon is burning

The growing number of fires are the result of illegal forest clearning to create land for farming. Fires are set deliberately and spread easily in the dry season.

The desire for new land for cattle farming has been the main driver of deforestation in the Brazilian Amazon since the 1970s.

Ironically, farmers may not need to clear new land to graze cattle. Research has found a significant number of currently degraded and unproductive pastures that could offer new opportunities for livestock.

New technical developments also offer the possibility of transforming extensive cattle ranches into more compact and productive farms – offering the same results while consuming less natural resources.

2. Why the world should care

The devastating loss of biodiversity does not just affect Brazil. The loss of Amazonian vegetation directly reduces rain across South America and other regions of the world.

The planet is losing an important carbon sink, and the fires are directly injecting carbon into the atmosphere. If we can’t stop deforestation in the Amazon, and the associated fires, it raises real questions about our ability to reach the Paris Agreement to slow climate change.

The Brazilian government has set an ambitious target to stop illegal deforestation and restore 4.8 million hectares of degraded Amazonian land by 2030. If these goals are not carefully addressed now, it may not be possible to meaningfully mitigate climate change.

3. What role politics has played

Since 2014, the rate at which Brazil has lost Amazonian forest has expanded by 60%. This is the result of economic crises and the dismantling of Brazilian environmental regulation and ministerial authority since the election of President Jair Bolsonaro in 2018.

Bolsonaro’s political program includes controversial programs that critics claim will threaten both human rights and the environment. One of his first acts as president was to pass ministerial reforms that greatly weakened the Ministry of the Environment

Regulations and programs for conservation and traditional communities’ rights have been threatened by economic lobbying.

Over the last months, Brazil’s government has announced the reduction and extinction of environmental agencies and commissions, including the body responsible for combating deforestation and fires.

4. How the world should react

Although Brazil’s national and state governments are obviously on the front line of Amazon protection, international actors have a key role to play.

International debates and funding, alongside local interventions and responses, have reshaped the way land is used in the tropics. This means any government attempts to further dismantle climate and conservation policies in the Amazon may have significant diplomatic and economic consequences.

For example, trade between the European Union and South American trading blocs that include Brazil is increasingly infused with an environmental agenda. Any commercial barriers to Brazil’s commodities will certainly attract attention: agribusiness is responsible for more than 20% of the country’s GDP.

Brazil’s continued inability to stop deforestation has also reduced international funding for conservation. Norway and Germany, by far the largest donors to the Amazon Fund, have suspended their financial support.

These international commitments and organisations are likely to exert considerable influence over Brazil to maintain existing commitments and agreements, including restoration targets.

5. There is a solution

Brazil has already developed a pioneering political framework to stop illegal deforestation in the Amazon. Deforestation peaked in 2004, but dramatically reduced following environmental governance, and supply change interventions aiming to end illegal deforestation.

Environmental laws were passed to develop a national program to protect the Amazon, with clearing rates in the Amazon falling by more than two-thirds between 2004 and 2011.

Moreover, private global agreements like the Amazon Beef and Soy Moratorium, where companies agree not to buy soy or cattle linked to illegal deforestation, have also significantly dropped clearing rates.

We have financial, diplomatic and political tools we know will work to stop the whole-sale clearing of the Amazon, and in turn halt these devastating fires. Now it is time to use them.

Thousands of fires are ravaging the Amazon rainforest in Brazil – the most intense blazes for almost a decade.

The northern states of Roraima, Acre, Rondônia and Amazonas have been particularly badly affected.

However, images purported to be of the fires – including some shared under the hashtag #PrayforAmazonia – have been shown to be decades old or not even in Brazil.

So what’s actually happening and how bad are the fires?

There have been a lot of fires this year

Brazil has seen a record number of fires in 2019, Brazilian space agency data suggests.

The National Institute for Space Research (Inpe) says its satellite data shows an 85% increase on the same period in 2018.

On Monday, the sky in São Paulo blackened due to smoke drifting from the fires 2,700 km (1,700 miles) away. Politicians and environmental activists are taking a stand against Brazilian President Jair Bolsonaro, blaming the fires on his policies.

But it’s a complex story, and online discussion of it has been riddled with misinformation, misleading photos and errors. To fill in the gaps and bust some common myths, we asked you to send us your questions on the Amazon fires.

We chose a sample of the many questions we received and where we didn’t know the answer, we enrolled the experts.

1) Why are there fires? Is it Bolsonaro’s men doing it to clear rainforest for mining/farming etc? – Alex

Brazilian journalist Silio Boccanera argues that some fires at this time of year – the dry season in Brazil – are to be expected. But many of the fires burning through the Amazon are believed to have been started deliberately.

President Bolsonaro has not condemned deforestation and supports clearing the Amazon for agriculture and mining.

“So it’s a combination of natural phenomena with locals feeling comfortable enough to do it because the government has not made any effort to prevent it,” Mr Boccanera says.

He thinks that smaller groups of people are more responsible for starting the fires than big corporations selling beef and soy, which could run the risk of being boycotted.

Although the big corporations are not innocent, they are better informed, he says.

But smaller groups – who benefit from destroying areas of the forest for farming – have gone ahead because they have not been stopped by authorities, Mr Boccanera explains.

Although deliberate fire-starting has always been a problem, it has never been seen to this extent. Mr Boccanera says perpetrators now know that if they are caught, they won’t be punished.

2) The number of fires seems like a bad metric, because the size of fires varies. Is there year-on-year data on the total area affected? – Peter

This is a fair point – Brazil’s satellite agency found there’s been an 84% increase in the number of fires compared with the same period in 2018. It detected more than 74,000 fires in Brazil between January and August – the highest number since records began in 2013. Most of those were in the Amazon.

But does this mean more land is being burned? After all, we could be looking at 74,000 tiny fires.

The truth is we don’t know yet, but the evidence points towards more land being consumed.

We don’t have the full picture at the moment, partly because many fires are still burning. We asked Copernicus, the European Union’s earth observation programme, and they said the best way to assess how destructive these fires are is to look at how much carbon dioxide is being released.

So far this year, the equivalent of 228 megatonnes has been released, according to the Copernicus Atmosphere Monitoring Service. This is the highest level since 2010.

At some point in the future, there should be more detailed satellite information about how much land had been burned, but that information isn’t available yet.

3) What’s being done to stop the fires? – Paul

President Bolsonaro is coming under growing political pressure to end the burning of the Amazon – France’s President Emmanuel Macron has even threatened to scrap a huge trade deal between the European Union and South America as a result.

But warnings by themselves don’t put out fires. There do seem to be some signs, however, that Brazil’s government is taking action on that front.

Mr Bolsonaro says he is calling in the armed forces, who have more resources to tackle the fires, including the use of helicopters and aeroplanes to drop water.

However, journalist Silio Boccanera says that he considers this “just talk”.

Mr Boccanera says he believes the attitude at the top of government needs to change. Before, people believed deforestation needed to be prevented. But now “people are burning without fear”, he says.

4) The coverage on this subject has only come to light recently because of the #PrayforAmazonas and #PrayforAmazonia hashtag. Why have you not reported it? – Jake

We and other news outlets have published several reports in recent weeks about the extent of deforestation in the Amazon – here’s one report we wrote on 2 July, another from 20 July and another from 2 August.

But the extent of the fires has only recently become clear. It was not even being reported very widely in Brazil.

The first real sign vast burning was taking place came when a daytime blackout, caused by smoke from the Amazon, hit Sao Paulo on Monday.

We first published an article on Tuesday afternoon, just a few hours after our colleagues at BBC Brasil, and we’ve kept updating it ever since.

At 23:29 on Tuesday, we published an article about the new satellite data that was released that day, which for the first time highlighted how serious the extent of the fires was. This article immediately became the lead story on the BBC News website internationally.

The #PrayforAmazonas hashtag was first used about two hours later. This, and others such as #prayforrondonia have become trending topics around the world.

5) Is this a natural, healthy way the forest self-clears for new growth? – Lucy

As Lucy suggests, there is a case to be made that some fire-adapted forests benefit from fires – they can help clear the forest and allow trees space to grow stronger.

But this is not the situation right now in the Amazon, says Yadvinder Malhi, Professor of Ecosystem Science at the University of Oxford. “These are fires that we are concerned about,” he says. The humid forests of the Amazon have no adaptation to fire and suffer immense damage. Almost all fires in humid forests are started by people.

He believes the driving force behind the fire is human rather than natural.

While statistics show that 2016 also saw a significant number of fires in the Amazon, this was considered a “drought year”- when there is naturally less rain so the forest is drier and therefore more fire-prone.

But 2019 has not been a drought year. Professor Malhi says there is such a large number of fires because people have lit them.

6) How quickly does the Amazon rainforest regenerate after a fire? – Emily

“The forest takes around 20-40 years if it’s allowed to regenerate,” says Prof Malhi.

But any fires that are currently burning will leave the surviving trees more vulnerable to drought and repeated fires.

Prof Malhi is worried that if the Amazon is hit by fires every few years large parts of it will shift to a degraded shrubby state.

“Once you’ve had multiple fires there’s the chance of permanent damage,” he says.

7) If this current trend were to continue at its present rate, how long would the Amazon rainforest area survive? – Christopher

“We are at an early stage where we can still do lots to save the forest,” says Prof Malhi. About 80% of the Amazon is still intact.

But he says that climate change and deforestation are a dangerous combination. A reduction in rainfall would create dry conditions for fires to spread.

If 30-40% of the Amazon was cleared, then there would be a danger of changing the forest’s entire climate, he says.

In the years before 2005, Brazil had an extremely high rate of deforestation.

“If Brazil were to return to that, it would take around 50-60 years to deforest 40% of the Amazon,” Prof Malhi says. “But in eastern and southern Amazonia it would take only 20-30 years to reach that threshold.”

8) What percentage of oxygen does the Amazon supply? – Tom

Our colleagues from BBC Reality Check spent most of the day on Friday getting to the bottom of this.

Many claim on social media that the Amazon produces about 20% of the world’s oxygen. It’s widely quoted – by campaign groups and well-known figures, including Emmanuel Macron and footballer Cristiano Ronaldo.

But academics say this is a very common misconception, and that the figure is less than 10%.

Oxygen is released by plants during the process of photosynthesis, where sunlight and carbon dioxide are converted into energy in the form of carbohydrates.

A large proportion of the world’s oxygen is produced by plankton, explains Professor Malhi. He says of the oxygen produced by land-based plants, about 16% comes from the Amazon.

But this isn’t the whole story. In the long run, the Amazon absorbs about the same amount of oxygen as it produces, effectively making the total produced net zero.

Professor Jon Lloyd from Imperial College London says although the Amazon produces a lot of oxygen during the day through photosynthesis, it absorbs about half of it back through the process of respiration to grow. Further oxygen is used up by the forest’s soil, animals and microbes.

The fires are also emitting carbon monoxide – a gas released when wood is burned and does not have much access to oxygen.

9) Will the smoke from these fires have an effect on global weather in future months? – David

Prof Malhi says the immediate effect of the fires will be on the climate of South America. Reduced rain fall is likely, leading to a more intensive dry season.

“The carbon emission could contribute to global warming,” he adds, but the longer term global impact is “more difficult to pin down”.

10) How are these fires affecting the indigenous people? – Samantha

Just this week, 68 fires were registered in indigenous territories and conservation areas, the majority in the Amazon, according to Jonathan Mozower from Survival International, which campaigns for indigenous rights.

“It’s hard to overstate the importance of these forests for indigenous peoples,” he says. “They depend on them for food, medicines, clothing and a sense of identity and belonging.

But the incentives to steal these resources are high and “sadly it’s not a question of one or two rogue actors”, Mr Mazower says. He says this could be the “worst moment for the indigenous people of the Amazon” since the military dictatorship, which ended in the 1980s.
