Brazilian Amazon deforestation falls to the lowest level since 2016 monitoring began

Brazil's National Institute for Space Research reported that deforestation of the Amazon rainforest fell to 2,874 square kilometres, or 287,400 hectares, from August 2025 to July 2026. The drop was a 37 percent annual decline. The level is the lowest since the institute's satellite monitoring began in 2016. The figures cover that twelve-month window.

Deforestation is the clearing of forest. A lower annual figure means less forest was recorded as cleared than in the comparison year. The report states both the area and the percentage decline. It does not list the states inside Brazil that contributed most of the remaining clearing.

Satellite monitoring since 2016 is the baseline for the record-low claim. The institute is the body named as the source. The report does not describe the satellite system. It does attach the record to that monitoring era rather than to all of history before satellites.

The area can be read as 2,874 square kilometres or as 287,400 hectares. Those are two units for the same reported area, not two different clearings. The percentage, 37, is the annual decline. No separate figure is given for fires versus deliberate cutting.

No law or enforcement action is cited as the cause in the short note. The item is a measurement. It does not say deforestation has stopped. It says the measured loss fell to the lowest level of the satellite era and by 37 percent year on year.

Other environmental stress in the same week included heat records and wildfires outside the Amazon. Those events are not folded into the 2,874 square kilometre figure. The Amazon number stands as an annual deforestation total from August 2025 through July 2026.
