Classificação da capacidade de uso das terras da Microbacia do Riacho Una, Sapé, PB

The growing expansion of agricultural activities without consideration of the potentialities and limitations of land constitutes a potential source of environment degradation. This work aimed to evaluate the physical proprieties of lands in the micro bosin of Una, Sapé in the state of Paraiba, Brazil, using the classification of the land use capacity . The area is located in the eastern part of the Paraíba state, between the geographical coordinates: 35o 08' 16" and 35o 15' 12" longitude, West of Greenwich and 06o 59' 18" and 07o 05' 42" latitude South. The adopted procedures utilized geoprocessing techniques and the integration of information was made in the Geographical Information Systems Idrisi Kilimanjaro, version 14.0. The system of soil use capacity was adopted to evaluate land. The results obtained demonstrated that the micro basin of stream Una presents satisfactory results with an indication that approximately 60% of its land may be used for agricultural purposes.
