METHODOLOGICAL APPROACH TO DETERMINE THE CAPACITY FOR ENVIRONMENTAL RESILIENCE IN WATERSHEDS

The determination of resilience capacity constitutes an important tool for environmental conservation and preservation. aim the present study was to evaluate lower course basin Poti River (LCPR) in state Piauí northeastern Brazil. For such, analyses were performed natural socioeconomic aspects area. A geographic information system used interpreting identifying main existing risks. images edited using SPRING 5.2 ARCMAP 10.3. Environmental determined by calculating index (ERI) based on two additional indexes: (NRI) municipal social vulnerability (MSVI). low urban areas river due greater pressure environment as a result demographic density exploitation resources. In contrast, rural (86 percent LCRP) showed moderate-to-high degree resilience, occurrence large predominantly covered with vegetation. reflects various public strategies adopted administrators. Another finding that method developed evaluating analysis is planning management basins terms sustainable development its uses different areas.
