                         in the Paraty region can add more instability to the natural 
                         landslides susceptibility of the municipality. Aiming to provide 
                         instruments and alert the government, is presented here an 
                         evolution of Landslides Susceptibility Maps of the years 1973, 
                         1986, 1993 and 2008. The methodology used was based on the IPTs 
                         methodology, combining in GIS environment, landsliderelated 
                         factors as slope, aspect, curvature, geology, geologic structures 
                         and land use. For the 1973 scenario, the municipality area was 
                         divided in 43.72% of low susceptibility, 46.85% of medium 
                         susceptibility and 9.43% of the high susceptibility areas. At 
                         1986, 40.37%, 49.54% and 10.09% was occupied by low, medium and 
                         high susceptibility respectively and at 1993, 40.05%, 49.69% and 
                         10.26% respectively. Finally, the 2008 scenario shows 39.16% for 
                         the low susceptibility area, 50.18% for the medium and 10.66% for 
                         the high susceptibility. Since 1973, with the opening of 
                         Rio-Santos highway (BR-101), there is a continuous shrinkage of 
                         low susceptibility areas and a growth of middle and high 
                         susceptibility landslides areas. The forested areas have declined 
                         in all susceptibility classes, while the human occupation has been 
                         growing within them. Currently the landslides risk is not a 
                         serious problem, except in the vicinity of roads and access 
                         routes, which can be found scars from old and recent landslides. 
                         But with the non-planning human occupation expansion the situation 
                         may evolve dangerously. This paper is like a warning to local 
                         government.",
