Uso e ocupação do solo na bacia hidrográfica da Barragem do Bezerro : uma abordagem ambiental

Abstract

This study presents an environmental analysis of the Bezerro Dam watershed, located in the municipality of José de Freitas, in the state of Piauí, Brazil. The objective of the study was to analyze land use and land cover within the watershed of the Bezerro Dam. The research was conducted based on field visits, photographic records, georeferenced mapping, and a literature review. The results indicate that disordered land use and occupation, deforestation, burning practices, improper waste disposal, and the discharge of effluents cause significant environmental degradation. Agricultural activities and land subdivision were also observed within Permanent Preservation Areas, contributing to the loss of riparian vegetation, the development of erosive processes, and sedimentation. The proposed mitigation measures include the reforestation of riverbanks, planning of urban expansion, sustainable soil management, and the promotion of environmental education. It is concluded that integrated watershed management is essential to ensure ecological balance and promote environmental conservation of natural resources.
