Bacia hidrográfica do rio das Ostras: proposta para gestão ambiental sustentável

Abstract

This dissertation presents an environmental analysis of the Ostras River Basin through surveys of physical, biological and anthropomorphic characteristics of the macroregion where the basin is located. The river basin was used as the base area for use management and ground occupation, allowing the elaboration of diverse assessment instruments capable of evaluating existing ecosystems, resulting in community politics with a social vision. Although river basins are under state and federal jurisdiction, the major conflicts in occupation occur in the cities, impacting the local environment, leaving the municipal administration responsible for enforcing pollution reduction and environmental compensation. The Ostras River Basin is almost entirely situated in the city of same name, in the State of Rio de Janeiro. The characteristics analyzed in this dissertation point to the necessity of developing a Management Plan for this basin with the aim of preserving the existing ecosystems: promoting environmental education, developing pollution reduction programs, monitoring water quality and sewage and water conditions, soil and riverbank erosion, promoting recovery of riverbank vegetation, preserving ecological diversity, resulting, thus, in global improvement of the social conditions of the region.
