As mudancas no uso da terra ao longo da historia tem gerado negativas consequencias para Mata Atlântica, deixando-a apenas com cerca de 10% de florestas maduras, com uma reducao expressiva dos reservatorios de agua e degradacao de bacias hidrograficas. Nesta pesquisa se diagnosticou o padrao atual e potencial de ocupacao e uso da terra numa microbacia hidrografica no Municipio Sao Miguel do Anta, Minas Gerais, Brasil. Esta pesquisa tambem teve como prioridade desenvolver um plano de manejo e conservacao do recurso hidrico da comunidade. A bacia hidrografica e ocupada atualmente por pequenos e medios agricultores correspondendo um total de nove propriedades, que mantem diferentes atividades de producao agricola e pecuaria, principalmente do cultivo de cafe, milho, feijao, eucalipto e granjas de frango de corte como parte do sustento economico familiar. Os resultados desta pesquisa revelam o padrao de uso e ocupacao de uma microbacia no Sudeste do Brasil, onde a maior proporcao de area e destinada para atividades de producao agricola e pecuaria. A partir deste padrao de ocupacao e das estimacoes de consumo de agua nas diferentes propriedades, propoe-se um plano de manejo preliminar com algumas premissas para a conservacao e recuperacao desta microbacia. Destaca-se a importância dos sistemas agroflorestais e corredores biologicos como acoes imediatas de reabilitacao de areas degradadas e restauracao ecologica, com a finalidade de reduzir as perdas de agua por escoamento superficial, assim como a perda e degradacao de solos. A B S T R A C T Changes in land use throughout history have generated negative consequences in the Atlantic Forest, leaving it with only about 10% of mature forests, such as a reduction of water reservoirs and degradation of hydrographic basins. In this research the current pattern and potential of land use and use in a hydrographic basin in the Municipality of Sao Miguel do Anta, Minas Gerais, Brazil, was diagnosed. This research also had as a priority to develop a management and conservation plan of the water resource of the community. The hydrographic basin is currently occupied by small and medium-sized farmers, corresponding to a total of nine properties, which maintains different agricultural and livestock production activities, mainly of coffee, corn, beans, eucalyptus and chicken farms as part of the economic sustenance family. The results of this research reveal the pattern of use and occupation of a microbasin in the Southeast of Brazil, where the largest proportion of area is destined for agricultural and livestock production activities. From this occupation pattern and water consumption estimates in the different properties, a preliminary management plan with some premises for the conservation and recovery of this microbasin is proposed. It is important to emphasize the importance of agroforestry systems and biological corridors as immediate actions for the rehabilitation of degraded areas and ecological restoration respectively in order to reduce water losses due to runoff, as well as soil loss and degradation. Keywords: Agroforestry; biological corridor; Permanent preservation areas; rehabilitation of degraded areas.
