The Sustained Land Capability, obtained through overlaying soil and slope maps (Figure 6) showed that almost 5396 of 
mpared to the area belongs to class IVe with limitations of foil and erodibility, being necessary the adoption of careful 
large and management practices. Land Capability Map and the Land Use Map overlaying, generated the Land Planning Map, 
presented in Figure7. This new layer, produced through GIS analysis is very useful to decision making in the process of 
planning. This analysis indicates areas which presents a appropriated land occupation. In other words, the land 
occupation is classified as appropriated when soil loss associated with the land use is not higher the accepted erosion 
tolerance. The watershed has 34% of the area classified as “Appropriated with restrictions”. Normally these areas 
occur in a slope gradient between 9-12% and soils with high erosion susceptibility, besides to be cultivated with 
sugarcane that requires specific management practices to reduce the soil loss.
