Indonesia’s forest fire destruction in 2019 far worse than official estimate
- Land burned nearly twice that officially reported; deforestation rate slowed in 2017-2020
- Indonesia says it is committed to reducing deforestation, but environmental groups call for greater transparency

Indonesia’s devastating forest fires in 2019 burned nearly twice as much land as was officially reported, according to a recent study, raising concerns among environmental campaigners over the government’s transparency regarding deforestation.
The Southeast Asian country, which has the largest rainforests outside the Amazon and Congo, has razed large swathes of land to accommodate its palm, pulp and paper industries.
The fires in 2019 blanketed Indonesia and the region with haze, causing 900,000 people to report respiratory illnesses and costing US$5.2 billion in losses, the World Bank said.
The study published in the Earth System Science Data journal in November found 3.1 million hectares (7.7 million acres) were burned in 2019 – an area bigger than Belgium – compared to 1.6 million hectares reported by the forestry ministry.
“We observed a larger damaged area than official estimates because groundbreaking technology enabled us to detect more small burns and more very large ones,” one of the study’s authors, David Gaveau said. “We used better satellite data, machine learning and Google’s supercomputers.”
Nonetheless, in line with official data, the study found that the rate of deforestation in Indonesia had fallen over the last four years, though its calculations differed, Gaveau said. When he first reported his findings in December 2019, Indonesian authorities said his research was not credible as it was not peer reviewed at the time.
