A Perenização de rios através da construção de açudes para o combate à seca no semiárido nordestino

This article analyzes the perennialization of the Jaguaribe, Piranhas Açu and Capibaribe Brazil’s rivers, from the construction of dams along their courses, due to the need to capture water to supply municipalities that suffer from the scarcity of this water resource in the Region East Northeast Atlantic Hydrographic from Brazil. The research has a bibliographical and qualitative approach. The results of the investigation showed that, although the construction of dams are seen as simple political practices, they cause environmental impacts such as the deforestation of riparian forests on the banks of these rivers. Thus, through reflections on the theme, it is understood that these works do not mean a definitive solution, but a guarantee of securing, with dignity, the inhabitants of the hydrographic region
