Processo de urbanização da bacia hidrográfica do córrego melancias, em Montes Claros, MG

Abstract

The several existing streams in the urban perimeter of the municipality of Montes Claros, MG, have been inadequately used for sewage disposal and improper disposal of solid waste, accumulating in loss of water quality, death of aquatic life and environmental contamination. The objective of this work was to evaluate the environmental impacts caused by the urbanization of the Melancias stream watershed, in the municipality of Montes Claros-MG, through the identification and characterization of environmental impacts, for subsequent proposition of mitigating measures for its recovery and preservation. The methods used for the evaluation of environmental impacts were Ad Hoc, Interaction Matrices and Interaction Networks. The site visits and the application of environmental impact assessment methods made it possible to identify and characterize the impacts, and to evaluate them. Due to the population growth and urbanization process that this watershed suffers, there was a predominance of negative impacts, the most severe being deforestation, illegal extractivism, and inadequate disposal of solid waste. Mitigating measures, compensatory measures, and enhancing measures were proposed for the environmental impacts observed. It was possible to conclude that a large part of the negative impacts occurred in the biotic environment, while the predominance of positive impacts occurred in the anthropic environment.
