Abstract

The recharge portion of Guarani Aquifer has more than 100.000 km2 in the Brazilian country, which is comprised by eight states with their particularities. The aim of this work is to classify recharge area of the Guarani Aquifer´s as Pedomorphoagroclimatics Domains  to subsidize environmental studies, over all the ones related to risk evaluation and sustainable management of areas. The two methodologies  Morphoclimatic Domain (AB’SABER, 1970) and Pedobioclimatic Domain (RESENDE et al., 1995) were jointed and adopted as a new concept. Considering agricultural uses, this procedure allows to consider the ecological tetrahedron purposes and the selected parameters commonly used in studies for environmental risk evaluation. For each region or state, the classification in domains considered differences among the physical variables, soil, morphology, agriculture activity and climate, which were taken as mean values or the most representative information. The results showed a stratification of the area in eight different domains, with subdivisions in some cases, making possible inferences about an incipient risk characterization.
