Hot Spots Occurrence in the Dynamics of Deforestation In The Amazon Rainforest

In mitigating climate change and ecosystems preservation that are unique and indispensable to the life of the planet, efforts are being made to reduce current levels of deforestation and degradation of tropical forests. In the arch of deforestation of the Amazon forest, studies on the occurrence of fires and the dynamics of deforestation are frequent in the literature on several aspects such as soil management, climate and vegetation change and forest resilience. This work presents an analysis of the relationship between deforested areas and the occurrence of fire outbreaks observed from January 2007 to November 2018, in a study area of approximately 36,000 km2, corresponding to the area covered by a Landsat-8 scene. Further, it was performed a correlation of fire outbreaks occurred in and near the forest area from the boundaries of the deforested areas from 2015 to 2018. Annual fire outbreaks data were obtained through the Queimadas Program of the National Institute for Space Research (INPE) from 2007 to 2018, the deforestation polygons from the Project for Deforestation Monitoring in the Amazon Forest by Satellite (PRODES) and the INPE's Real-Time Detection System (DETER-B) from 2007 to 2018. The temporal analysis revealed an increasing of the incidence of fires with the increasing of deforestation in that period, evidencing the systematic use of fire as a means of suppressing biomass. In the last 4 years, the high occurrence of forest fires between 500 to 1000 m from the edge boundaries of the deforested areas, showed a considerable degradation of the forest and a probable decrease of forest resilience.
