Due to the historical process of land occupation and the Brazilian agrarian politics, the household agriculture production has been under pressure by the agrarian structure composed of owners of large farms. Silvânia (GO) is a representative municipality of this reality, where the small and medium farms exist together with the large farms, located in the geographic and economic interstices. In order to study the factors that limit the improvement of the household agriculture in Silvânia, an environmental analysis of the municipality was conducted by matching information related to the physical factors with the different agriculture methods. The results of this study attest that the owners of household agriculture are concentrated, in its majority, on more erosion susceptible soils and the owners of large farm on the areas where the
relief is plain and the soil is deep. Hence, it was possible to understand the spatial distribution of agricultural models which supports the actions to consolidate the household agriculture.
