Avaliação ambiental utilizando matriz de indicadores na área urbana de Nossa Senhora das Dores/SE

Abstract

The emergence and/or growth of cities without an appropriate urban space occupation planning makes Brazilian cities present the typical problems of urban centers in less developed countries. This manner of urbanization reflects in problems which interfer in environmental quality and, consequently, in the life quality of the residents. Due to the intense changes provoked by human action on the urban ecosystem, it shows its working and characteristics more and more different from the natural systems. The pressures exerted by human activities and their dynamics on natural environment, makes it necessary the search for a new development pattern with a guarantee of a natural capital to future generations. That provokes discussions about the urban process sustainability. With the objective of making an environmental assessment of the urban area of small cities, a methodology based on the approach model called PEIR (Pressão, Estado, Impacto, Resposta PSIR (Pressure, State, Impact, Response) was applied in this work with the elaboration of an urban environmental indicator matrix. The application of this matrix in the small city of Nossa Senhora das Dores, located in the state of Sergipe, was based on the assumption of the urban process (non) sustainability. The PEIR matrix indicator characterization provided, according to the causes and the agents, the comprehension of the environmental degradation process. The results revealed a non sustainable urban process and showed anthropic pressures on environment with degradation and permanence of an environmental debit due to the lack of responses from the society and the local managers. These results can be useful as subsidies to the increment of new actions from public policies, providing a way that leads to the city sustainable development.
