The destruction and degradation of the world’s largest rainforest has happened in fits and starts. Spanning eight countries, the Amazon rainforest is home to an enormous concentration of life and culture. About half of it is located in Brazil, which is also the heart of the destruction.
The forest’s fortunes have risen and fallen with political leadership. About 17% of the Amazon has already gone, replaced by vast cattle ranches, mines and soy fields. If that figure reaches 20% to 25%, scientists believe the rainforest will lose the ability to sustain itself, with disastrous consequences.
“We stand exactly in a moment of destiny: the tipping point is here, it is now. The peoples and leaders of the Amazon countries together have the power, the science, and the tools to avoid a continental-scale, indeed, a global environmental disaster,” wrote the Brazilian scientists Carlos Nobre and Thomas Lovejoy, the godfather of biodiversity, in 2019.
Between 2004 and 2012, Brazil’s president, Luiz Inácio Lula da Silva, and the first Rousseff administration achieved huge drops in deforestation – it fell by 84% in that period. This was an internationally rare achievement; Indonesia is the only other large tropical country to have achieved a significant drop in deforestation over a prolonged period.
Since then, the progress has been reversed, especially under the leadership of the far-right president Jair Bolsonaro, when a ferocious war on nature took place, including attacks on the territories of the Indigenous peoples who live in the Amazon.
Illegal land mining and farming grew as the funding for environmental agencies was cut and and protections removed, with an area larger than the size of Belgium being cleared.
Lula has vowed to end deforestation in the Amazon but it will not be easy. In February, two months into his administration, deforestation reached the highest levels ever recorded, although a 68% drop was achieved in April.
As the Brazilian Amazon has been cleared, its composition has changed. From 1985 to 2021, satellite imagery shows that farming and mining have replaced virgin forest, with cattle ranching and soy in particular taking up large areas.
While mining has significant impacts on water quality, and causes other forms of pollution, it takes up tiny areas compared with agriculture, which has been the major driver of forest loss.
The view from space
The impact on the Amazon is so vast it can be seen from space. In 2020, Dom Phillips reported from Novo Progresso, a settlers’ town in Pará state, at the beginning of the fire season. Google Earth imagery between 1980 and 2023 shows how the area has been transformed.
“Fires – three times more common in Amazon cattle farming areas – are used to clear forest for pasture. Fragile law enforcement means fines are ignored. And when the loopholes that allow farmers to sell cattle raised on illegally burned or deforested land are taken into account, the future for Novo Progresso’s forests is not bright. Instead, it is black with smoke,” Phillips wrote after speaking with local people, some off the record for fear of repercussions from Bolsonaro’s government.
There are hundreds of places like Novo Progresso that have been transformed in the Brazilian Amazon, being industrialised as the forest disappears.
