Studies on the management of river basins with a geographic approach have not yet been widely disseminated; thus, this paper provides a proposal aimed at contributing to advances in this field, through the applications of geo-technologies to the analysis of the integrated management of the Lajeado Amarelo river basin, in Três Lagoas, state of Mato Grosso do Sul, Brazil. Results were obtained by applying a systemic approach as the basis of the integrated management, as well as through a theoretical and technical discussion regarding the study of river basins. The management of this particular river basin was addressed on the basis of the analysis of types of land use and the assessment of their impacts (according to the management of the river). The article also analyzes the influence of each type of land use on the conservation of the basin and makes proposals for changing land use and their viability. [ABSTRACT FROM AUTHOR]

This study aims to analyze the conflicts that occur regarding the use and occupation of the territory in areas of protection and conservation of nature in the Chapada dos Veadeiros Microregion, a mosaic composed of human occupations with diversified interests: environmental protection, represented by environmentalists; agribusiness, under the domain of “ruralists”; mining, with strong presence of small prospectors and mining companies; tourism, which is growing, but worrying environmentalists; small landowners, who need to survive, but are confined to small areas surrounded by agricultural companies; and by ancestry, with the presence of African Brazilians, the Kalunga Quilombola Community, in addition to the non-governmental organizations (NGOs), having a strong presence in the area. In geographic terms, this Microregion is a true patchwork, where the limits of the cities that compose it are interlaced with the limits of the Pouso Alto Area of Environmental Protection, with the Reserve of the Brazilian Savanna Biosphere and with the Historical and Cultural Heritage Site of the Kalunga, all with their specific legislations. Within this web, conflicts are a reality, and the actors diverge in their interests. [ABSTRACT FROM AUTHOR]
