                         Bonita Reservoir, Sao Paulo State, Brasil. Barra Bonita Reservoir 
                         Basin had undergone intense land use/land cover changes in the 
                         last decades, including the fast conversion from pasture into 
                         sugarcane. In this respect, this study answers to the lack of 
                         information about the variables (criteria) which affect the 
                         pollution potential of the drainage basin by building a Geographic 
                         Information System which provides their spatial distribution at 
                         sub-basin level. The GIS was fed by several data (geomorphology, 
                         pedology, geology, drainage network and rainfall) provided by 
                         public agencies. Landsat satellite images provided land use/land 
                         cover map for 2002. Ratings and weights of each criterion defined 
                         by specialists supported the modeling process. The results showed 
                         a wide variability in the pollution potential of different 
                         sub-basins according to the application of different criterion. If 
                         only land use is analyzed, for instance, less than 50% of the 
                         basin is classified as highly threatening to water quality and 
                         include sub basins located near the reservoir, indicating the 
                         importance of protection areas at the margins. Despite the 
                         subjectivity involved in the weighing processes, the 
                         multi-criteria analysis model allowed the simulation of scenarios 
                         which support rational land use polices at sub-basin level 
                         regarding the protection of water resources.",
