Use and Occupation of the Hydrographic Micro-Basin of Igarapé do Mariano in the Municipality of Manaus-Amazonas

Abstract

Objective: To analyze the dynamics of the use and occupation of land based on the planning and sustainability of natural resources at the micro-basin of Igarapé do Mariano.   Method: This study is characterized by a quali-quantitative approach based on field-collected primary data, followed by data treatment in a laboratory and data analysis in an office. It presents an exploratory nature, with research and information regarding a micro-basin.   Results and conclusion: The urban expansion of Manaus advances towards the Mariano micro-basin, likely leading to an intensified use and occupation of land. The recent interventions on the routes and areas of leisure at the riverbed have been provoking negative environmental impacts that are typical of the urban micro-basins of Manaus, which have been and continue being destroyed as the city expands.   Implications of the research: Based on the realizations from the analyses of the use and occupation of land, the research is expected to contribute to a planning policy for the territory, be it the Mariano micro-basin or other geographical areas.   Originality/value: The study’s value lies on the peculiar location of the studied area, which is situated in the transition vector of urban expansion; on the lack of studies and of deeper information on the subject; on the use of a Remotely Piloted Aircraft in the field work for the photographic and aerophotogrammetric survey, which has proven to be an effective support for the study of the geographical area. All these aspects are of high relevance to the acquired knowledge and could potentially contribute to socioenvironmental actions.
