Abstract:
Deforestation, caused by human activities, leads to the loss of vegetation and natural resources that are essential to ethnic communities. This study addressed the lack of information on the anthropogenic processes of deforestation in ethnic territories by analyzing its causes. The deforestation rate and the geospatial distribution of socioeconomic activities were evaluated between 2016 and 2023. A generalized linear model (GLM) with gamma distribution and logarithmic link function was implemented to explain the causes of deforestation. Between 2016 and 2018, the highest rate of deforestation was in the indigenous community. In this community, agriculture (40%) and forestry (33%) were the main economic activities, while in the afro-descendant community, mining (29%) and forestry (26%) were the most important. The GLM showed that deforestation increases with distance from existing forests, indicating that more remote areas are targeted for new economic activities, such as agricultural expansion or timber extraction. This geospatial analysis highlights the relationship between socioeconomic activities and the loss of vegetation cover in ethnic territories.
