Aplicação do sistema de indicadores de sustentabilidade força motriz-pressão-estado-impacto-resposta (FPEIR) para a gestão de recursos hídricos em João Pessoa-PB.

Abstract

This study aimed to identify the sustainable use of the water resources to João Pessoa, the state capital of Paraíba, located in the basin of the river Paraíba. The main driving forces were identified, pressures, state of the environment and impact on the water resources held by this city in the basins in which it operates, as well as the measures of existing and potential responses. The research used the Sustainability Indicator System Driver-Pressure-State-Impact-Response (DPSIR) to achieve their goals. After fitting the model, were selected 26 indicators to represent the sustainability of basins and indicators 26 have been identified, some of which were analyzed together. These indicators helped to analyze the availability and quality of the surface and groundwater in the region studied. The application of DPSIR model showed that the sources of the two basins that supply Joao Pessoa are not being managed sustainably. The results show that the population of Joao Pessoa exerts considerable pressure on the water resources in the basins studied in both aspects: qualitative and quantitative. It is evident also need to be carried out frequent assessments of the conditions of sustainability of watersheds involved. This requires periodic updating of data related to basins, developing studies that can assist in the integrated planning.
