Why Amazon Deforestation Has Fallen to a Record Low

How much has Amazon deforestation fallen?

Brazil’s National Institute for Space Research, known as Inpe, reported that 3,335 square kilometres of Amazon forest were cleared between August 2025 and July 2026. That is the smallest annual total in the country’s records, which began in 1988. ¹²

The figure is nearly 42% below the 5,731 square kilometres reported for the previous year. The Guardian describes the data as coming from Prodes, a satellite-based monitoring series it calls the most accurate measure of deforestation. ¹²

These numbers refer to forest clearance in the Brazilian Amazon over a particular 12-month period. They are not a measure of all forest loss across every country in the Amazon region, nor do they say that deforestation has stopped.

What may be driving the drop?

The reports place the decline within a period of lower deforestation during President Luiz Inácio Lula da Silva’s administration. The Guardian says the rate has slowed by 71.2% since 2022, the year before Lula’s administration began. That comparison shows a marked change over time, but by itself it does not prove which policies caused it. ²

The sources describe the reduction as a government achievement and connect the figures to Brazil’s efforts to curb forest destruction. But the material available here does not spell out which enforcement steps or other measures had the greatest effect. It would therefore be misleading to assign the fall to one specific policy. ¹²

The broader pressures remain relevant. Cattle and soybean farming are among the activities associated with forest clearance in the Amazon, although the supplied reporting does not quantify their role in this year’s result. ³

Why does the election matter for the forest?

The latest figures arrive before Brazil’s presidential run-off on 25 October. The Guardian reports that Lula is facing Flávio Bolsonaro, son of former president Jair Bolsonaro, and describes the candidates as having sharply different visions for the rainforest. ²

That makes the durability of the decline an open political question. The result is a record for the period measured, not a guarantee that future totals will keep falling. The sources do not provide enough detail to predict how either candidate would affect deforestation if elected.

Lula has stated a goal of reaching zero illegal deforestation by 2030. That is a stated target, not a result already achieved. ¹

What do these figures mean for the Amazon?

The Amazon is the world’s largest tropical rainforest, and most of it lies in Brazil. The forest also extends into Peru, Colombia and other South American countries. ¹ A decline in Brazil’s forest clearance is therefore important, but it is not a complete picture of what is happening across the whole Amazon region.

Lower annual clearance means less forest was recorded as cleared during this measurement period than in the previous one. It does not establish that every part of the forest is secure, or that other environmental pressures have eased. The reports warn that deforestation and illegal resource exploitation have been pushing the Amazon closer to a climate tipping point, but they do not give a forecast for when, or whether, such a threshold would be reached. ¹

For readers, the clearest takeaway is both encouraging and limited: Brazil has reported its lowest recorded annual clearance, while continued progress depends on what happens next. Future figures will show whether this is a lasting change.

What is still unknown?

The available reports establish the scale of the latest decline and its timing. They do not provide a detailed breakdown of the causes, or show how much each government action contributed.

The election outcome and future policy choices are not known as of October 16, 2026. Nor do these figures alone establish whether the decline will continue in later measurement periods.
