Using Satellite-Derived Data to Understand Land Cover Drivers of Fire Ignition and Spread in the Brazilian Amazon

Abstract:

Fire in the Brazilian Amazon biome has been shown to be largely anthropogenic and is linked to a pattern of deforestation and agricultural expansion. Burning has been on the rise in the past decade, with thermal anomalies suggesting that the year 2020 had the second-highest number of fire detections since 1998, followed only by 2019. Although Brazilian national policy has banned human-caused fires in natural vegetation or during specific times of year, it fails to account for fires that escape their intended boundaries, or uncontrolled fires. Studies have shown that burned area from uncontrolled fires, which often start in pastureland and'leak'into surrounding forest, may even be larger than the area of intentional deforestation. Uncontrolled fires result in damage to crops or grazing land, disturb forest ecosystems, and increase carbon emissions. To better understand the land cover drivers of fire spread, we used fire …
