A RELAÇÃO ENTRE FOGO FLORESTAL E DESMATAMENTO NA AMAZÔNIA

Between 2013 and 2020, approximately 42% of fire hotspots in the Brazilian Amazon occurred in previously undisturbed forests, affecting an estimated 18,000 square kilometers annually. While only 11% of fire-affected forest areas transitioned to clear-cut deforestation within three years, fire serves as a strong regional indicator of risk, with high rates of subsequent deforestation occurring in the surrounding areas. This association is particularly strong in rural settlements and public land holdings, where fire may facilitate land grabbing. Regional analysis shows an intensification of this fire-deforestation link in states such as Acre, Amazonas, Pará, Rondônia, and Roraima, especially around 2017.

• Between 2013 and 2020, an average of 42% of annual fire hotspots in the Brazilian Amazon were located in forests that had never been deforested, potentially affecting over 18,000 square kilometers of forest per year.
• Fire in the Amazon is not systematically used as an initial stage for vegetation removal, as only 11% of forest areas affected by fire were converted to clear-cut deforestation within three years.
• Although local conversion is low, fire acts as a regional risk indicator because there is a high probability of subsequent deforestation in the vicinity of fire-affected areas; for example, the percentage of areas with subsequent deforestation within 0.5 kilometers ranged between 20% and 50% in 2017.
• The association between fire and subsequent nearby deforestation is approximately 35% stronger in rural settlements and public land holdings compared to the average for all land tenure categories.
• In public land holdings, the pattern suggests that fire may be used as a cheap and fast method for occupying territory during the land grabbing (grilagem) process.
• Regional analysis shows that Pará and Mato Grosso concentrate the highest proportions of fire and deforestation, with Pará accounting for 33% of fire hotspots and 39% of deforested area between 2013 and 2020, and Mato Grosso accounting for 18% and 23% respectively.
• There was a significant intensification of the relationship between fire and subsequent nearby deforestation in the states of Acre, Amazonas, Pará, Rondônia, and Roraima, particularly in 2017.
