%X With the increasing demand for fuel, food and fiber that follows population growth, the effort to provide sufficient water for agriculture causes additional pressure on the environment. The conflicting interests between the use of the water and the protection of strategic sources reinforce the needs for a legislation adaptation, territorial organization and a sustainable water resources management. This study aimed to map land use in an outcrop area of the Guarani Aquifer System (GAS) and generate information for a better planning and discussion of public policies for groundwater resources conservation in areas with irrigated agricultural production. The study area was the Ribeirão do Jacú watershed, Tejupá - SP, Brazil, located entirely in the outcrop area of GAS, a high vulnerability region. From supervised satellite image classification of land use and occupation using Geographic Information System (GIS), it was possible to identify and to quantify the major activities developed and the conflicts of the actual land use in the watershed in the period between 2002 and 2011. The results showed the presence of agricultural and livestock systems in Permanent Preservation Areas (PPA) and an improvement of irrigated agriculture in areas closed to the outflow of the basin, indicating a trend of local production intensification.
