Abstract

The concern with environmental conservation and sustainable use of resources is recent and thus, the actions still not implemented. The lack of care for the environment has caused the effect of pollution and reducing the amount of water, especially in heavily populated areas, which creates serious conflicts of water use. Occupations cluttered space, for maximum profit in production systems with minimal cost, demonstrate the lack of commitment to environmental issues. Hence, there is urgency to respond adequately to this problem, this study aims to identify environmental conflicts, caused from human occupation at the characterization of spatial distribution of environmental impacts in the basin of the river Vacacaí-Mirim in the city of Santa Maria / RS and seek to establish ways and means of recognition of where major damage occurs to the environment in riparian areas. To achieve this goal, it was considered advancement of human occupation on the permanent preservation areas that generate the most significant impacts on the environment with various types of pollution and therefore reducing the amount and quality of bringing change in the ecosystem as a whole. The lack of public policies in relation to watersheds is another important factor that was considered.
