Conteúdo:	Our aim in this work was to map the main land-use and land-cover changes at 25 cities located at the watersheds of the Mogi-Guaçu and Pardo rivers over the last 27 years. We focused on coffee and sugarcane crops at these region, known as Mogiana Paulista. We updated the sugarcane crop areas to the year 2015 using maps produced by the Canasat project. For land-use and land-cover classification of these 25 cities in 2015 we used a Google Earth image file in a GIS environment. The method we used was on-screen visual image interpretation of high-spatial-resolution images, which were later compared to data from 1988. Along the 27- year period, coffee crops expanded approximately 80%, from 67.3 thousand to 123.8 thousand hectares. The 25 cities which are the main coffee producers at Mogiana Paulista showed concentration of coffee crops, which make up a total of approximately 111 thousand hectares. Both coffee and sugarcane may still advance onto parts of these cities' areas that are currently used as pastures, which the land-cover that loses more areas. Pastures still occupy 322 thousand hectares, or about 30% of the area of these 25 cities, and 252 thousand of these hectares feature slope degrees which are adequate for the mechanized harvesting of both sugarcane and coffee.
