A fragilidadade das vertentes e os impactos ambientais na Zona Oeste da cidade de Manaus/Am

Abstract

Given the alterations in urban relief due to spatial occupations and reorganizations, the discussion about landscape modifications and the environmental impacts that emerge from the appropriation of relief, especially slopes, is always revisited. Human activities in the physical environment, mainly in urban sites, cause transformations in the landscape, both in physiography and physiology. Society, when appropriating and occupying the relief, begins to interfere directly in morphodynamic processes (pedological, geomorphological, hydrological, among others). Thus, the different morphologies of the relief undergo an intense process of sculpting, the result of which is evidenced in forms that can be of degradative origin (such as erosive), depositional (technogenic deposits, anthropogenic landfills) and interventionist (such as slopes and earthworks) (PEDRO MIYAZAKI, 2014). Given the discussions about the occupation of relief in urban areas, the present research proposes to investigate the fragility of slopes and their environmental impacts in the West Zone of the city of Manaus, more specifically in the neighborhoods of Glória, São Raimundo and Santo Antônio, seeking to understand the environmental problems triggered by occupations. Therefore, the objective of the research is to analyze the environmental fragility of the slopes of the neighborhoods of Glória, São Raimundo and Santo Antônio, located in the West Zone of Manaus/AM. And for specific objectives: To carry out a historical rescue of the occupation process of the slopes of the neighborhoods of Glória, São Raimundo and Santo Antônio; To identify the main compartments of the relief of the neighborhoods of Glória, São Raimundo and Santo Antônio; To identify the different types of occupation on the slopes in the neighborhoods of Glória, São Raimundo and Santo Antônio. The methodology of this research will be based on "The four levels of geographical research" proposed by André Libault (1971), being an organization of information at the compilatory, correlational, semantic and normative levels. Thus, it is expected that the results will provide information about the occupation of the study area and possible alterations in the slopes and margins of rivers and streams present in the area and their fragilities that will be defined based on the methodological proposal of environmental fragility of Ross (1994) who defined 5 classes of environmental fragility classification that is very weak, weak, medium, strong and very strong.
