Análise geoecológica das paisagens e planejamento ambiental da Bacia do Rio Maranguapinho, Ceará, Brasil

Abstract

Urban planning is presented as a management tool, designed primarily for the control and use of natural resources. The implementation of interventions in urban rivers for environmental rehabilitation purposes is increasingly common. Modifications of natural spaces give way to urban structures and the occurrence of positive and negative effects in the short term is notorious. Thus, this thesis proposes to examine whether urban interventions serve the purpose of recovering the environmental quality of urban watersheds through an integrated analysis of geoecology landscapes, where the Maranguapinho River basin. Located in the metropolitan area of Fortaleza - RMF, Ceará, the basin has many environmental problems, and the disorderly occupation on the banks of the main channel. The river Maranguapinho is marked by a variety of uses, such as: human consumption, irrigation and agriculture, industry, recreation, mineral extraction, livestock and animal consumption, solid waste disposal, domestic sewage discharge and dilution and removal of dumps. These problems are a direct result of the illegal occupation, the lack of urban planning and environmental management actions and land use. The methodology of Geoecology of Landscapes was adopted as a method to support the analysis of environmental and evolutionary context of the Maranguapinho river landscapes. The methodology used in its integrated analysis showed that the implementation of an urbanization project in the river can contribute to recovery of environmental quality. However, the implementation of the works without actions that include participative management, ultimately makes the redevelopment project in a mere urban intervention. it is clear that the actions of environmental restoration and land use planning to be effective, they must be associated with the implementation of strategies of environmental education policies and actions.
