• Abstract:

  The present work aims to estimate the use of pesticides by sugarcane in the watershed of the Aguapeí River. To this end, the research relied on data provided by Mapbiomas (2021) on sugarcane expansion in the study area - having the years 2002 and 2020 as a time scale - in addition to the limit of the subbasin area, provided by SIMA (2020) and the estimate of the use of pesticides per hectare in sugarcane cultivation, according to Pignati, Oliveira and Silva (2014). Thus, with the aid of a Geographic Information System (GIS) the use of pesticides was quantified among the subbasins of the study area. In addition to office activities, field work was carried out in order to analyze the dynamics of the landscape and corroborate the mapped elements. The results showed that between the analyzed period there was a significant change in terms of land use, with the substitution of pasture for sugarcane expansion, resulting in an exponential increase in the use of pesticides. Therefore, this work contributes to research that aims to estimate the use of agrochemicals in watersheds, in addition to assisting in studies on the environmental impacts resulting from the use of pesticides.
