RESUMO:

The emergence of spontaneous occupations and the improper use of the soil, as well as the inadequate management of water resources, result in several problems to the environment and people who live and depend on this environment. This study was carried out on the Urumari igarapé microbasin, located in the city of Santarém, Pará, and aimed to identify and analyze the spatial and temporal dynamics of land use and cover changes in the igarapé microbasin, between 1987 and 2018, through techniques of digital image processing and remote sensing. In addition, we sought to investigate the perception of older people residing along the igarapé on possible local processes of environmental degradation, respecting the timeline and comparing such perception with data acquired through geotechnologies. The method for remote sensing included an on-site visit to strategic points of the main course of the Urumari stream, supervised classification by the Maximum Likelihood algorithm, images of the Landsat 5 TM satellites, Landsat 8 OLI and community interviews. The analysis of the remote sensing data was elaborated using the QGIS software and its complements. The results show the loss of dense vegetation and the considerable increase of built or exposed soil. We concluded the studied environment has undergone deep human intervention in the last 31 years, without any kind of repair of the native vegetation. The method for collecting qualitative data included the Problem-Centered Interview technique applied to 31 persons and, to analyze the interviews, the Collective Subject Discourse (DSC) technique was used.
