Análise multitemporal do uso e cobertura do solo no município de Cocal (Piauí)

Abstract

This study explores the impact of land use and occupancy practices on environmental degradation, propelled by the application of geotechnologies for analysis. The objective is to conduct a multi-temporal assessment of land use and occupancy in Cocal - PI, employing the Normalized Difference Vegetation Index and maps from the MAPBIOMAS platform. Satellite images from the Landsat TM satellite for the years 2010 and 2020 were employed and processed using QGIS 3.22.3 to generate georeferenced Normalized Difference Vegetation Index maps. The MAPBIOMAS platform was utilized to compare Normalized Difference Vegetation Index results and gather land use information. The findings underscore an expansion in urban areas, agricultural growth, and reduction in forested and aquatic regions. These outcomes substantiate the georeferenced maps, signifying the prevalence of native coverage in the majority of Cocal's territory, particularly within permanent preservation zones. The conclusion highlights the imperative for interventions encompassing oversight, public awareness, and environmental policies to alleviate degradation and advance the promotion of sustainable utilization of natural resources
