Brazil Amazon deforestation alerts rise 9% in September, annual trend still down 27%

Deforestation alerts in the Brazilian Amazon rose 9% year-on-year in September to 350 sq km, according to INPE. Despite the monthly uptick, cumulative deforestation for 2026 is down nearly 27% versus last year, indicating a continued downward trend. The increase may signal localized pressure or seasonal variation, but the annual decline suggests policy enforcement is holding.
