In the first half of 2026, satellite monitoring recorded a sharp decline in Amazon deforestation, falling to 1,295 km² – a 32 % drop from the same period in 2025 and the lowest total since the DETER‑B system began in 2016. Officials linked the reduction to reinforced environmental enforcement that started in 2023, while noting possible threats from El Niño and pending legislative changes.

A July Imazon report warned that, despite the overall decline, several protected areas in Mato Grosso remain under intense pressure. The Guariba‑Roosevelt Extractive Reserve and Xingu Indigenous Park were among the ten most deforestation‑pressured sites in the Amazon Legal, prompting calls for stronger monitoring and enforcement. Follow‑up Imazon analyses confirmed these reserves stayed in the top‑ten pressured sites for the second quarter and highlighted Mato Grosso, Pará and Acre as states with the highest number of pressured protected units. Amazonas hosted the greatest concentration of indigenous territories facing strong pressure, with the Yanomami territory ranking first, while Pará continued to record the most pressured environmental protection area (Triunfo do Xingu) for the fifth year.

Real‑Time Deforestation Detection System data for August 2025‑July 2026 showed Amazon alerts fell 36.9 % to 2,874 km², the lowest since 2016 and 55.6 % below the ten‑year average; Cerrado alerts dropped 7.8 % to 5,119.46 km². State‑level reductions were strongest in Mato Grosso (‑49 %), Amazonas (‑46.7 %), Pará (‑25.5 %) and Rondônia (‑41.2 %); Roraima was the only state with an increase (+32.5 %). President Luiz Inácio Lula highlighted the results as evidence that Brazil can meet its zero‑deforestation target for 2030 if the current pace continues, citing the reinstated Amazon Action Plan and IBAMA’s 2026 embargoes on 350,000 ha of illegal clearing (815,000 ha nationwide since 2023).
