The Southwest Planning Region of Goiás (RPSG) is part of the recent and rapid Brazilian sugarcane expansion in the Center-South of the Brazilian Savannah named Cerrado, from 1985 to 2016. So this article emphasizes the periods before, during and after the expansion. The sector’s growing created an environment of competition for the best productive areas between agroindustrial complexes in the region, mainly grains and meat. The main evidence of that is found in changes in land use, as sugar cane has been directly and indirectly replacing agricultural, pasture and Cerrado remnant. The influence of this sugarcane expansion on the spatial dynamics of RPSG in 1985, 1995, 2005, 2010, 2013 and 2016, is analyzed considering the previous, concomitant and subsequent period of this expansion. To do so, geotechnologies were applied to analyze the succession and conflicts of uses. The results showed that sugarcane advanced upon the agricultural and livestock areas, but also on the natural ones, in search of the best soils, which is related to the greater profitability of the crop, interfering in the production of food and in the areas of native vegetation.
