Análise de vulnerabilidade socioambiental das bacias hidrográficas do setor oeste da cidade de Manaus/AM

Abstract

The socio-environmental problematic of Manaus, especially the urban watersheds of the city, is the theme explored in this research, because it is a great highlight in the eyes of those who pass through streets and avenues cut by waterways in Manaus, and also by people who visit and explore the city. Because of the environmental and also social problems, these small rivers are in a situation of great risk, indicating environmental fragility and fragility in the ecosystem of the basins. The present research sought to analyze not only the natural issues of the channels, such as drainage, sinuosity and channel density, but also socioeconomic issues of the population living in these areas, in order to know and identify economic and social patterns of those who inhabit the areas near the hydrographic channels in the western sector of the city. Data such as illiteracy rate, monthly income distribution, color, and ethnicity were addressed with more emphasis in the first unit of the research. About the housing of these people, pertinent information about the basic sanitation of the residences was used, and patterns were sought. Data such as sanitary sewage were approached with emphasis. In general, it was identified that the watersheds of the western sector suffer a strong problem of pollution, mainly caused by domestic and commercial sewage, since most of the sewage from residences and establishments is not treated, contributing to the pollution of nearby channels. It was also found that most of the population living in risk areas and/or near waterways are low income, mainly in areas closer to the city center, such as São Raimundo and Glória neighborhoods.
