             abstract = "This work establishes a semi-automatic methodology to define and 
                         evaluate the Environmental Protection Areas (EPA), in the 
                         Para{\'{\i}}ba River Basin, Brazil, taking account the land use 
                         and the water quality. The development of this work started from 
                         the water capitation point of Guaratingueta city located on the 
                         stream that runs through the city. From ASTER GDEM data the 
                         drainage network and the basin catchment was automatically 
                         extracted. Landsat images for the dates of 1989, 2001 and 2014 
                         were digitally classified and the land uses were mapped, 
                         considering the area of permanent protection (APP) for drainage, 
                         respecting the limits indicated by Brazilian forest code. Scenes 
                         from the RapidEye satellite were used to answer questions of 
                         classification, due to good image definition. The study showed 
                         that in 1989, the total area classified as APP, 37.59% were 
                         anthropized, reaching 37.98% in 2001 and 36.98% in 2014. In a few 
                         years it was possible to associate data from water quality, 
                         measured directly at the capitation. In 2001 the water quality 
                         data showed that the intensive use of fertilizers drained into the 
                         Guaratingueta stream by rice paddies was seriously affecting the 
                         water supply of the municipality. In 2008 measures for water 
                         quality at the capitation point showed that the water resources 
                         were still impacted by agricultural activities from the rice 
                         fields. So, this work indicates the need for revitalization of the 
                         APP inside the EPA Guaratingueta in order to meet the law, protect 
                         watersheds and also avoid large investments in water treatment
