Forest loss in the Amazon fell by 23.5% in 2025 compared with the previous year.
This drop contributed to a 21% national reduction in overall clear-cutting—the lowest level recorded since 2016. Federal governance and control plans, such as Brazil's Plan for the Prevention and Control of Deforestation in the Amazon, have been important drivers of this reduction. However, turning this temporary relief into lasting protection requires extending effective enforcement to other biomes across Brazil.
As a researcher studying environmental policies and forest degradation, I still see significant political obstacles ahead. To understand the challenge of sustaining deforestation reduction, Brazil must look to its own history. Between 2004 and 2012, the country reduced Amazonian deforestation by almost 85% through rigorous enforcement, real-time satellite monitoring and strong institutional coordination.
That progress was later undermined. During President Jair Bolsonaro's administration from 2019 to 2022, the severe dismantling of Brazil's political institutions weakened environmental enforcement. The number of federal environmental inspectors dropped from 1,311 to 691, while regulatory changes restricted agents' authority to destroy machinery used in environmental crimes.
This staffing shortage caused a near-total collapse in the number of fines issued. Deforestation reached a 15-year high in 2022, surging past 13,000 square kilometers (5,000 square miles). This crisis left federal agents exposed to severe threats from armed loggers and a complete lack of government support.
Under President Luiz Inácio Lula da Silva's administration, which began in 2023, overcoming this setback required a shift toward much faster enforcement. Brazil combined real-time satellite monitoring with immediate digital embargoes. Issued remotely by federal environmental agencies, these digital shutdown orders block illegal activities at a small fraction of on-the-ground costs.
