Land use and occupation on the banks of the Comprido River, Rio de Janeiro – RJ

Abstract

Since the beginning of colonization, the hydrographic basins of the city of Rio de Janeiro have been incorporating dynamics of anthropic transformations arising from the urbanization process, with more intense interventions in the 20th century, having effects on their river channels. The present work aims to evaluate the types of land use and occupation that are prevalent on the banks of the Comprido river and their respective relationship with its drainage. The data used were acquired through the Pereira Passos Institute, which, in a GIS environment, were manipulated, generating the longitudinal profile of the Comprido river and the 2018 environmental scene of its banks. Subsequently, the data were quantified and the values organized in a table for comparative purposes. As a result, it was observed that the predominance of occupation by residential areas in places of lower altitude, and tree and shrub cover in higher altitude areas, which are threatened by the expansion of slums towards Tijuca National Park. Thus, this work can provide support to the public authorities in the planning of this environmentally susceptible area.
