Análise espaço - temporal do uso e cobertura do solo em Cristino Castro - PI: um estudo comparativo entre 2005, 2014 e 2024

Abstract

This study analyzed the spatiotemporal dynamics of land use and land cover in the municipality of Cristino Castro, Piauí, covering the years 2005, 2014, and 2024. The methodology consisted of processing orbital data from the MapBiomas platform (Collection 10.0) using QGIS 3.44.3 software to create thematic maps and quantify the areas. The results revealed that the Savanna Formation remains the predominant class, occupying 84.33% of the territory in 2024, despite having suffered a reduction of approximately 10,153 hectares over the analyzed period. A significant increase was observed in the areas of Mosaic of Uses, which jumped from 0.69% in 2005 to 4.96% in 2024, and in Pastures, which reached 3.68%. Furthermore, continuous regeneration of the Forest Formation was identified, possibly associated with the buffer zone of conservation units. It is concluded that the landscape of Cristino Castro is undergoing a process of fragmentation of native vegetation, highlighting the importance of geospatial monitoring for the sustainable management of natural resources in the Cerrado of Piauí
