The Environmental Risk Assessment (ARA) of pesticides, under the responsibility of Ibama, is part of the procedure for registering a pesticide in Brazil. The main objective of this project was to compare the worst-case scenario adopted by Ibama for the ARA of pesticides in water bodies, with the most representative scenarios of soybean cultivation prevalent in Brazil. A methodology was developed to map water basins with potential for contamination by pesticides used in agriculture. Through it

There is currently a strong interest to comprehend, evaluate and minimize anthropic impacts on hydric resources. It has been particularly studied the effect of removing native vegetal covering over water availability and quality. In order to estimate the effects of changing vegetal covering over hydric resources, hydrologic modeling becomes an adequate tool. However, hydrologic models need great amounts of information, which in most times are unavailable. On the other hand, data obtained through
