According to Auriga Nusantara research, in 2025, deforestation occurred over 433,751 hectares in Indonesia.

Auriga defines deforestation as "the reduction of natural forest cover", which includes the loss of dryland forests, peat swamp forests, and mangrove forests, whether primary or secondary forests.

In 2025, the most significant deforestation was recorded on the island of Kalimantan, with a deforestation area of 158,283 hectares, equivalent to 36% of the total national deforestation area.

"Kalimantan once again recorded the greatest extent of deforestation, making it the region with the highest deforestation rate for consecutive years since 2013," said Auriga Nusantara in a press release (March 31, 2026).

Other islands with significant forest loss include Sumatra Island, with a deforestation area of 144,150 hectares, equivalent to 33% of the total national deforestation area.

Next in line is Papua Island, which experienced deforestation covering an area of 77,678 hectares, equivalent to 18% of the total national deforestation area.

Meanwhile, deforestation in Sulawesi, Maluku, Bali-Nusa Tenggara, and Java islands combined reached 12% of the total national deforestation area, as shown in the chart.

"Deforestation is no longer a declining trend. The latest data actually show a surge that we need to be aware of," said Auriga in a post on their Instagram account @auriga_id (April 1, 2026).

"Behind these figures, there is lost forest, eroded living spaces, and long-term impacts on the environment," they said.
