Impactos ambientais da ocupação na paisagem do Projeto Lagoa Grande no município de Janaúba-MG

Abstract

The present work presents the process of changes in the landscape through the installation of the irrigation perimeter. The city of Janaúba, North of Minas Gerais, benefited from the Lagoa Grande Project. This environment stands out due to the concentration of the irrigation perimeter, implanted in the Lagoa Grande community, which can be considered as a landmark for the transformation of the rural landscape in the environment of the area under study. The present research had as objectives, to study the processes of impacts of population occupation, through the agricultural expansion, and the environmental quality of the landscape arising from the Irrigation Project in the Lagoa Grande community in the Municipality of Janaúba - MG. The methodology used was the bibliographic review for theoretical basis and the secondary research carried out on institutional websites. With the approval of the Ethics Council, CAAE number: 64487917.0.0000.5146, a data survey was carried out at the Association of Irrigants on the Left Bank of the Gorutuba River - ASSIEG, which provided reports on the data of the irrigation project and responded to the interview. The fieldwork was carried out by visiting the community's residents, which resulted in the construction of the historical environmental context of the landscape and by collecting water to detect the quality of the water through analyzes of the physical-chemical and microbiological content, in addition to the mapping of the area under study with the multitemporal scale, using images obtained via satellite. It was found that the irrigation project has put pressure on the rural landscape, which has undergone serious changes, including the removal of riparian forest and the transport of material to the water resource, which is in the process of eutrophication, reflecting increasing interventions, being of great value an effective planning of actions that seek the recovery and the defensible means for the landscape of Lagoa Grande.
