Spatiotemporal dynamics of heat sources in Tartarugalzinho/AP from 2001 to 2022

Abstract

The study analyzes the spatiotemporal dynamics of heat sources in Tartarugalzinho, Amapá, from 2001 to 2022, highlighting the relationship between these hotspots and the El Niño and La Niña climatic phenomena. The research employed geospatial techniques to identify the density patterns of the hotspots and their correlation with deforestation and precipitation. The results show that areas near the Piratuba Biological Reserve are consistently vulnerable to wildfires, particularly during El Niño events. The study reveals that deforestation and agricultural expansion are significant factors influencing the occurrence of heat sources, suggesting the need for more effective conservation policies in the region.
