- Abstract
The use of fire in land management is almost omnipresent in rural and urban properties in the Amazon after the climate changes that have occurred in recent decades. Thus, the objective of this research was to analyse the temporal dynamics of the hotspots in the Southeast region of Pará between 2010 and 2017 and, consequently, to propose a pressure-response model for the current scenario. The data of hotspots were acquired from the AQUAM-T satellite, from the processing performed in the online database of the National Institute of Space Research (INPE) in the period understood and later employed GIS techniques for the creation of a surface of densities, using the Kernel estimator. The results signalled an alert to the mesoregion, especially to the municipalities that are part of the arc of deforestation. The year 2010 had the highest number of cases, with a strong influence of phenomena such as El Niño and human activities, which were responsible for the majority of outbreaks. The months with the highest records were August, September and October, representing 81% of the outbreaks referring to the total recorded, coinciding with the Amazonian winter period in the region, indicating the agribusiness environment as responsible for the environmental changes that occurred in recent years.
