AVALIAÇÃO DE IMPACTO AMBIENTAL EM PROPRIEDADES DE AGRICULTURA FAMILIAR NO CERRADO BRASILEIRO

Abstract

The natural elements extraction and the harmful substances emission cause major impacts on the environment. Thus, the Environmental Impact Assessment comes to systematically analyze these changes. This study aimed to evaluate the environmental impact on two rural properties Pr1 (Sítio JF) and Pr2 (Sítio Cabeceira) of a family farmers' settlement in the Brazilian Midwest, in Rio Verde - GO. The methodology Supported Novo-Rural (Weighted Environmental Impact Assessment), developed by EMBRAPA, was used, using a qualitative and quantitative approach, in five different dimensions: Landscape Ecology, Environmental Compartments Quality (Atmosphere, Water and Soil), Sociocultural Values, Economic Values and Management / Administration. Laboratory evaluations (water and soil analysis) and systemic observation in loco (analysis of social, cultural, economic parameters, etc.) were used. The property Pr1 had an environmental impact index corresponding to 77%, while in Pr2 the index was 74%. The main problems faced by Pr1 were for the Management/Administration Dimension. Regarding Pr2, the most deficient dimension was that of Sociocultural Values. Both presented low values for the soil environmental compartments dimension. However, in general, Pr1 showed a better Environmental Performance index of the Activity, especially regarding the water and atmospheric environmental compartments quality dimension. The dimensions Landscape Ecology, environmental compartments of air and water quality and economic values are within the compliance levels for a correct sustainable development in both Studied Sites.
