Avaliação de impacto ambiental (A.I.A.) da nascente do Bom Pastor UFRPE - UAG

Abstract

The environmental impact Assessment (E.I.A.) is one of the instruments of the National Environment Policy (PNMA), introduced in Brazilian by Law n º 6.938/1981, and is composed of several stages that intend to ensure an assessment of the possible impacts in a particular activity or undertaking can generate, in addition, contributes to future decision-making for activities with potentially polluting/degrading the environment. This monograph aims to evaluate the environmental impacts in the sources of the stream of “Bom Pastor”, located in Garanhuns – Pernambuco, quantifying them according to the methodology of the matrix of interactions proposed by Leopold and adapted by Rocha (1997) and so recommend mitigating and compensatory measures. In this, 108 crosses were made between the proposed actions and the environmental factors, where banknotes from 1 to 10 were attributed to magnitude and importance. The quantified environmental factors were physical and chemical characteristics of the earth, physical and chemical characteristics of the water, physical and chemical characteristics of the atmosphere, physical and chemical characteristics of the processes, biological conditions of the flora, biological conditions of the fauna, cultural factors uses of the territory, recreational cultural factors, aesthetic cultural factors and human interest, cultural factors: cultural level, cultural factors: services and infrastructure and ecological relations. The factor with the highest degree of deterioration found was "aesthetic cultural factors and human interest" presenting values of 38.90% of Magnitude and 59.72% of importance. The level of deterioration of the spring is 37.99%. From that value, mitigatórias and compensatory measures were recommended in order to seek improvements.
