Deforestation in Brazil’s Amazon rainforest reached a record high for the first six months of the year, as an area five times the size of New York City was destroyed.

From January to June, 3988 square kilometres were cleared in the region, according to national space research agency Inpe.

That is an increase of 10.6 per cent from the same months last year and the highest level for that period since the agency began compiling its current DETER-B data series in mid-2015.

Destruction rose 5.5 per cent in June to 1120 sq km, also a record for that month of the year.

The Amazon, the world’s largest rainforest, contains vast amounts of carbon, which is released as trees are destroyed, warming the atmosphere and driving climate change.

Deforestation is creeping deeper into the forest.

In the first six months of the year, Amazonas state in the heart of the rainforest recorded more destruction than any other state for the first time.

Jungle inferno

This year’s rising deforestation is also feeding unusually high levels of fires, which are likely to worsen in the months ahead, Manoela Machado, a wildfire and deforestation researcher at Woodwell Climate Research Center and University of Oxford, said.

Brazil recorded the highest number of fires in the Amazon for the month of June in 15 years, although those blazes are a small fraction of what is usually seen when fires peak in August and September, according to Inpe data.

Generally, after loggers extract valuable wood, ranchers and land grabbers set fires to clear the land for agriculture.

“If we have high deforestation numbers, it’s inevitable that we’re going to have high fire numbers as well,” Machado said.

“This is extremely bad news.”

Experts in Brazil blame right-wing President Jair Bolsonaro for rolling back environmental protections and emboldening loggers, ranchers and land speculators who clear public land for profit.

Conflicting claims

Bolsonaro’s office directed request for comment to the Environment Ministry, which said the government has been “extremely forceful” in fighting environmental crimes.

The ministry said that considering the 12 months through June, Inpe’s data showed deforestation declined 3.8 per cent from the same period a year earlier.

Environmentalists are banking on leftist former president Luiz Inacio Lula da Silva, who presided over a steep decline in deforestation during his presidency from 2003 to 2010, winning in October’s national election for a turnaround in Brazil’s environmental policy.

A poll released this week showed Bolsonaro losing to Lula by 19 percentage points in an expected run-off.

Regardless, this year is likely to have high levels of deforestation and fires as loggers and land grabbers seek to capitalise on the weak enforcement ahead of a potential change in government, experts say.

“It’s very difficult to be optimistic for the next few months in the Amazon,” Romulo Batista, a forest campaigner for Greenpeace Brasil, said.
