Abstract

The study aimed to identify the environmental impacts of the occupation in risk areas in the city of Alagoa Nova-PB, aiming to propose adequate procedures for improvement of environmental quality and social. The identification and characterization of the qualitative impacts were realized from the use of the method list control-Check List, which consists of the list of consequences (impacts) from which they identify the impacts of a specific project. Identification and description of environmental impacts were based on data provided by the Brazilian Institute of Geography and Statistics-IBGE (2010) and the Brazilian Agricultural Research Corporation-EMBRAPA (1911-1990). From the analysis of the environmental impacts that was diagnosed between the negative environmental impacts of the ongoing expansion of settlements in urban areas stand out the most relevant vegetation removal; drastic changes in topography, sedimentation of watercourses and continuous erosion. It was observed also that through data collection, disposal of solid waste in the city of Alagoa Nova-PB represents a potential threat to local environmental resources, especially regarding the environmental quality of soil, air, and surface water therefore the presence of an open-air dumps as the main area of final destination of waste exposes the study area to these conditions, since it does not have the necessary infrastructure for the protection of environmental resources (soil, water, air and society), and affects the health and welfare of the population. Therefore, a policy aimed at the socio-economic development necessarily involves, sanitation policies and environmental quality.
