Drivers of fire anomalies in the Brazilian Amazon: lessons learned from the 2019 fire crisis

The study identifies a strong correlation between active fire anomalies in the Brazilian Amazon and deforestation, noting that the 2019 crisis was particularly severe in the states of Acre, Amazonas, and Roraima.

• The 2019 fire crisis was characterized by abnormally high monthly fire counts in the states of Acre, Amazonas, and Roraima, which were also distinguished by extreme levels of deforestation that year.
• Areas experiencing active fire occurrence significantly above the biome average in 2019 showed a strong link to historical and current deforestation: they had six times more deforestation in 2019, five times more in the five previous years, and three times more active fires in the three previous years.
• Analysis of the 2003-2019 period shows that roughly one-third of yearly active fires occurred within 1 km of deforested areas in the same year, and one-third of deforested areas were within 500 m of areas deforested the previous year.
