Estudos sobre a ocupação das vertentes e os impactos ambientais nos bairros Nova Ituiutaba I,II,III e IV – Município de Ituiutaba/MG

Abstract

The process of occupying geomorphological compartments for the purpose of building popular housing has increasingly provoked, on the slope, environmental impacts that have adversely affected the occupying population. Among the impacts, it is possible to mention the erosive processes, the silting of the streams, removal of the vegetation cover, the decapitation of the soil and the formation of technogenic deposits. This is mainly because of the capitalist mode of production and specifically by the interests of the urban space production agents who appropriate the geomorphological compartments (areas of topos, slopes and valley bottoms) to implement allotments that can serve different social classes. Some of these subdivisions are built away from the central area of the city, that is, in the peripheral or even discontinuous areas of the urban network, and there are several reasons for the agents of urban space production, one of them being real estate speculation. Thus, considering this scenario and analyzing the case of the city of Ituiutaba / MG, it was possible to carry out a case study in the southern sector of the urban network, focusing on the analysis of the occupation of the slopes of the Nova Ituiutaba I, II, III and IV.com the main objective of analyzing the process of occupation of the slopes and how this contributed to the acceleration of the geomorphological processes, besides identifying the main environmental impacts in the area. In order to carry out this research, it was adopted as methodological procedure the observations, through fieldwork for the recognition and identification of processes, erosive features and relief, besides the bibliographical surveys on the subject, which involved the search of documents with municipal public agencies, also mapping the area by satellite image and collecting soils at georeferenced points for granulometric analysis in the laboratory. The results obtained from the research showed that the Nova Ituiutaba subdivisions that are divided into four blocks of implantation built in two phases, totaling 1766 residences, of which 966 are already occupied, is very degraded due to the way the relief was occupied. In the bedside area of this tributary was identified a voçoroca that interdigitated to the affluent provoking a great modification in the natural dynamics of this place, in addition the occupation of the slopes where the landings are found was done without considering the dynamics of the natural processes (soils, hydrographic, geomorphological, etc.), which contributed to some negative impacts such as sedimentation of the fluvial channels, sediment entrapment in the sources of the tributary, formation of a technogenic deposit of the deforestation type of the riparian forest
