Environmental diagnosis of the Hydrographic Basin of the Mampituba River, south region of Brazil, using the DPSIR framework

Abstract

The objective of this work was to diagnose the water resources situation of the Mampituba River Basin (MRB), southern region of Brazil. The DPSIR matrix (Driving Force, Pressure, State, Impact and Response) method of socioenvironmental indicators was used. After synthesis and classification of the data, they were mapped by sub-basins. It was verified that the environmental sustainability of most of the MRB is in a regular situation. The main pressure-generating activities are agriculture, industry and urbanization, but overall anthropogenic pressure is low. However, the vulnerability of MRB is evidenced by the lack of water supply and sanitation infrastructure and monitoring, protection and environmental management actions, due to the lack of adequate response measures.
