Avaliação da sustentabilidade no município de Boqueirão-PB: uma aplicação do sistema de indicadores de pressão- Estado - resposta (PER).

Abstract

The society-nature relationships are (re) defined a long of the historic process, characterized by the men´s exploration on the environment, subsidizing their satisfaction, needs and desires. This exploratory logic developed the impacts in more varied orders, and scales, modifying mostly the dynamic ecosystemic and causing irreversibility of ecosystem cycles. The environmental quality is stands out, while conditions in which the environment can reproduce in their natural dynamics, in space and time, it doesn´t present rupture in their cosmetic cycles. Given the necessity of the mensuration and environmental quality, and quantification of their sustainability levels, indicators of Pressure-State-Response were used while. Representative tool of mensuration of the environmental quality municipal, adopting as proposed methodology, the construction of indices (showing alternatives to the problematic indicated in this study), that has generated the indices of quality of the environmental to the Boqueirão-PB city. In this way, it was established as general objective, to measure the environmental quality of the Boqueirão-PB city, through the use of the indicators of the sustainability of the Pressure-State-Response (PSR), determining the specific objectives addressing issues as: analyzing of the relations of society-nature and human interventions in the city of Boqueirão; coverage of the sanitary sewage system and the impacts impacts of launchings the launch of the impacts of organic waste "in nature" on local water bodies; multiple forms of water supply in the city, its quality and pressure exerted by relation demand-consumption in weir Epitácio Pessoa in Boqueirão-PB: production, management and solid waste management adopted by the municipality. As it relates to Urban Solid Waste, it emphasizes the deposition of solids waste, with the preponderance of the municipal landfill as a single storage means, so the absence of sustainable forms of treatment. In the field of water consumption, it has been detected in Epitácio Pessoa weir the disparate relationship between the quantity supplied and demand, Use exerting itself greater than the amount of flow, in which represent the intensive Boqueirão pressure supply of the system and imminent collapse scenario supply. Finally, the release of organic waste in the environment, presents itself as one of the most serious problems found by the lack of treatment plant and launching so "in nature" all the sewage of the city in the Paraiba River.
