摘要：This article presents a geoenvironmental picture of the hydrographic basin of the Rio Acarau (geology, geomorphology, pedology), located in the Brazilian northern Northeast, as well as the environmental problems that characterize it. The study area is located in a poor and extremely populous semi-arid region, with large environmental degradation of the river course and its plaine. It is necessary that regional authorities transform the hydrographic basin into a fundamental socio-economic and environmental planning unit, based on the surveys and geoenvironmental characterization of the area, to reverse the socioenvironmental degradation of the natural resource and allow territiorial growth based on sustainable development.
