Análise geoespacial e multitemporal de área queimada no município de Corumbá, Pantanal de Mato Grosso do Sul

Abstract

The Pantanal biome has been suffering, especially during recent years, episodes of fires in its vegetation, in a continuous and hideous way, making flora and fauna the biggest victims of this event, in addition to the consequences caused to the local community. During a certain annual period, especially when drought hits the biome, the incidence of fires in certain areas of the Pantanal is very common. For a better understanding and study, remote sensing is used to map and analyze changes in vegetation and the earth's surface caused by fires. Therefore, the objective of this study was the geospatial and multitemporal analysis of fires in an area of 346.89 km² located in the Porto da Manga region, in Corumbá/MS, between the years 2020 to 2024, in the months of June to September. Mapping was carried out using images from the Sentinel-2 satellite and data on fire outbreaks extracted on the BD Queimadas platform, from the National Institute for Space Research (INPE). Through visual photo interpretation of the images, the work resulted in the years 2022 and 2023 without any record of outbreaks, and the years 2020, 2021 and 2024 with the highest rates of fires, with recurrences in 159.96 km² and possible causes linked to management practices, burning for agricultural and pasture activities, and accidental or intentional burning on the banks of Estrada Parque, bordering south of the study area.
