Estimativa da expansão agrícola na região do MATOPIBA entre os anos de 2016 e 2022, a partir da classificação de uso e cobertura da terra do MapBiomas

Abstract

The MATOPIBA region has been affected by a significant territorial expansion of agriculture in recent years, causing a growing leap in the region's economy. As a consequence, the notable promotion of advanced technologies that enable monitoring of crop production. Geotechnologies have taken up more and more space, making geospatial analysis fundamental tools for behavioral changes in types of land use and cover. The present work aims to analyze, through images from the Sentinel-2 satellite classified according to land use and coverage by MapBiomas, the temporal behavioral changes in agricultural land use between the years 2016 and 2022, having as base year the 2016. In the methodology, the free code software QGIS and Dinamica EGO were used, which enabled data manipulation. To determine the area for agricultural use, satellite images in raster files were used in geoprocessing tools (reclassification and subtraction). In addition to vector data for the delimitation of federative units and in raster format for composing maps. The results represented on thematic maps show the visual changes of the areas considered as agricultural use within the period in relation to the base number and in a graph demonstrating the quantitative changes and highlight the importance of continuous monitoring of changes in land use.
