O Nordeste brasileiro historicamente e uma das regioes que mais exercem pressao sobre os recursos naturais. Nesta regiao o tipo climatico predominante e o semiarido, que passa por uma faixa de transicao semiumida. Ocorrem, em grande parte dessa regiao, solos de media a alta fertilidade natural, em geral pouco profundos em decorrencia de seu baixo grau de intemperismo. O objetivo do presente manuscrito e avaliar a adequabilidade do uso agricola das terras de uma area no sertao central do Estado do Ceara, levando-se em consideracao que os solos no semiarido brasileiro apontam a agricultura de subsistencia como uma das causas de impactos ambientais negativos, assim como o uso de tecnologias inadequadas, alem da pressao antropica para diversas finalidades. Os resultados apresentados sao fruto do cruzamento do mapa de uso e cobertura das terras com o mapa de aptidao agricola. Com base no mapeamento verificou-se que os solos da area apresentam restricoes quanto a determinados tipos de uso, como para lavouras, alem de nenhuma aptidao para silvicultura. Tambem verificou-se que a maior parte das terras encontra-se subutilizada, ou seja, com outros usos, principalmente pastagem e vegetacao nativa. Porem, o que requer maior cuidado sao as terras sobreutilizadas. A B S T R A C T The Brazilian Northeast is historically one of the regions that put more pressure on natural resources. In this region the predominant climate type is semiarid, which passes to zone of semiwet transition. Occur in this region, soils with medium to high natural fertility, in general, shallow, due their low degree of weathering. The objetive of this manuscript is to evaluate the adequability of the agricultural land use of an area in the central hinterland of Ceara State. The soils in the Brazilian semiarid are used by subsistence farming, which suggests negative environmental impacts, as well as the use of inappropriate technologies, in addition of the human pressure for several purposes. The data presented are the result of crossing between land use and cover map and agricultural suitability map. Based on the mapping was found that the soils of the area present restrictions to certain types of use, such as farming, and no capability to silviculture. Also it was found that most of the land is underutilized, with another uses, particularly grassland and natural vegetation. However, more care are required for super utilized lands. Keywords: GIS, fragility, agricultural management, semiarid.
