Deforestation in Brazil’s portion of the Amazon rainforest soared more than 88 percent in June compared with the same month a year ago, the second consecutive month of rising forest destruction under new right-wing President Jair Bolsonaro.

According to data from Brazil’s space agency, deforestation in the world’s largest tropical rainforest totalled 920 square kilometres.

The data showing an 88.4 percent deforestation increase is preliminary but indicates the official annual figure, based on more detailed imaging and measured for the 12 months to the end of July, is on track to surpass last year’s figure.

In the first 11 months, deforestation already reached 4,565 square km, a 15 percent increase over the same period in the previous year. That is an area larger than the US state of Rhode Island.

Environmentalists have warned that Bolsonaro’s strong remarks calling for the opening up of the Amazon for development and criticising the country’s environmental enforcement agency Ibama for handing out too many fines would embolden loggers and ranchers seeking to profit from deforestation.

“Bolsonaro has aggravated the situation … He has made a strong rhetorical attack,” said Paulo Barreto, a researcher at Brazilian NGO Imazon.

‘The Amazon is an icon’

The surge in deforestation comes as Brazil faces more pressure to protect its environment under the terms of the free trade deal between the European Union and South American bloc Mercosur agreed to last week.

The rainy season through April appeared to have held off a spike in deforestation that subsequently came with the dry season starting in May.

Bolsonaro’s office declined to comment, saying questions would be addressed by the environment ministry.

“We are adopting all measures to combat illegal deforestation,” Environment Minister Ricardo Salles said. “This week we had 17 enforcement teams simultaneously in all of the Amazon from Ibama.”

Brazil is home to 60 percent of the Amazon, which is the world’s largest tropical rainforest and is seen as vital to the global fight against climate change.

Grains trader Cargill, the largest privately held US company, said last month that the food industry would not be able to meet a pledge to eliminate deforestation in their supply chains globally by 2020 and committed to do more to protect native environments in Brazil.

While the final text of the EU-Mercosur deal has not been released, an outline from the EU states the agreement includes a provision that the Paris Agreement on climate change must be effectively implemented along with other commitments to fight deforestation.

French President Emmanuel Macron had warned last week prior to making the deal that he would not sign off on it if Brazil was to leave the Paris accord.

Greenpeace forest strategist Paulo Adario said “all indications” were that deforestation will worsen under Bolsonaro, but he hopes news of a large increase will put pressure on the government to take action.

“When they have the final numbers, if it is really a lot, this will be a nightmare for Bolsonaro,” Adario said.

“This is something that is really important from an international and Brazilian point of view because the Amazon is an icon.”
