Planejamento ambiental e a Gestão de recursos hídricos: um estudo na bacia hidrográfica do Rio das Ostras, município de Rio das Ostras/RJ

Abstract

In my professional practice as a biologist at the Rio das Ostras City Hall, I have the task of carrying out environmental analyzes to produce technical opinions and reports. The functions as biologist of the City Hall require external and internal activities to the Secretariat of the Environment, in which we are constantly faced with conflicting issues related to water resources, such as the occupation of Permanent Preservation Areas, flood plains and other humid areas. The territory of Rio das Ostras contains, in addition to the river basin that gave it its name, the basins of coastal lagoons and Rio das Pedras. Our study has as main focus the territory of the Rio das Ostras basin, which has sections of its main tributaries and springs located in the rural area. In the urban portion, part of the Jundiá River and the Rio das Ostras run. Thus, we propose, with this study, to raise the problems related to water resources and environmental management in the Rio das Ostras River Basin / RJ, aiming to contribute for the municipal river basins to be adopted as planning and environmental management units having, as principle, decentralized and participatory management. Thus, the methodology for the development of the project was qualitative research in a participatory way. Among the means for data collection, bibliographic and documentary research, field activities, semi-structured interviews and photographic record were used. It was found that both in the rural and urban areas these water courses suffer a marked degradation process. In the municipality there is an urgent need for updates and revisions of important management tools, such as the revision of the master plan, revision of the management plans of the municipal Conservation Units and of laws related to land use and occupation. As a product of the research, a technical report is presented to the Secretariat for the Environment, Agriculture and Fisheries, with a view to collaborating with environmental and water resources management.
