Análise da vulnerabilidade ambiental da bacia hidrográfica Riacho Talhada – semiárido alagoano

Abstract

The environmental analysis of the Riacho Talhada river basin in the Sertão de Alagoas aims to identify and understand the main environmental challenges and impacts that affect this region. Some authors, such as Oliveira et al. (2012), says that “the main environmental vulnerabilities of the Brazilian semi-arid region are erosion, the desertification process, the inadequate occupation of natural areas, the loss of biological diversity, and the scarcity of water”. To carry out the environmental analysis of the basin hydrographic, several studies and research were used that address the topic. Data were collected on deforestation, pollution, land use and other variables relevant to understanding the current state of the river basin, following the methodology of Crepani et al. ( 2001). Studies indicate that the river basin faces serious environmental problems, inadequate land use, associated with the lack of environmental preservation policies, contributes to the process of degradation of the river basin. The analysis carried out shows that the Riacho river basin Talhada-AL faces significant challenges in relation to environmental conservation. It is essential that protection and recovery measures are implemented, such as the establishment of permanent preservation areas, the regularization of land use and the development of sustainable management policies for natural resources.
