In the first 29 days of April, deforestation in the region totalled 1012.5 square kilometres according to data from national space research agency Inpe.

The agency, which has compiled the monthly DETER-B data series since 2015/2016, will report data for the final day of April next week.

April is the third monthly record this year, after new highs were also observed in January and February.

Destruction of the Brazilian Amazon in the first four months of the year also hit a record for the period of 1,954 sq km, an increase of 69 per cent compared to the same period of 2021 - clearing an area more than double the size of New York City.

Deforestation in the Amazon has soared since right-wing President Jair Bolsonaro took office in 2019 and weakened environmental protection. Bolsonaro argues that more farming and mining in the Amazon will reduce poverty in the region.

"The cause of this record has a first and last name: Jair Messias Bolsonaro," said Marcio Astrini, head of Brazilian advocacy group Climate Observatory, in a statement.

Bolsonaro's office directed questions to the ministries of environment and justice. The ministries said in a joint statement the government was making major efforts to fight environmental crimes and that police and environmental authorities were cooperating on an operation to combat deforestation in five Amazon states.

Even with deforestation already on the rise, Climate Observatory said its analysts were astounded by such a high reading in April, which is part of the rainy season when the muddy forest is harder for loggers to access.

Preservation of the Amazon is vital to stopping catastrophic climate change because of the vast amount of climate-warming carbon dioxide it absorbs.
