             abstract = "Water is a key resource for human well-being, furthermore, 
                         essential for agricultural production systems and socioeconomic 
                         maintenance. In the Goi{\'a}s state one of the economic bases is 
                         agriculture that uses predominantly surface water for irrigation 
                         purposes. Besides, urban supply also depends on surface water, 
                         resulting in a competition that may lead to the development of 
                         conflicts within the influence area of catchment basins. Given 
                         this, in this paper we analyzed the expansion of center pivot 
                         irrigation in catchment basins for supplying urban water demand in 
                         the Goi{\'a}s state, aiming to mapping the risk of water 
                         conflicts. Landsat TM and OLI images were used to map some years 
                         (1984, 1990, 1996, and 2015) and others were obtained from the 
                         governmental database (2000, 2003, 2012, and 2013). From the 185 
                         identified areas, 45 of them presented that type of irrigation 
                         system. In the first date (1984), these basins comprised only 200 
                         ha irrigated by center pivots, however in 2015 the irrigated area 
                         expanded to 33.800 ha. On the other hand, water demand for 
                         irrigation only exceeded the maximum granted in the S{\~a}o 
                         Jo{\~a}o da Para{\'u}na basin (125%). Other five basins were 
                         demand between 40% and 60% of the granted volume. In the remaining 
                         basins (39), the water demanded for irrigation was less than 40%. 
                         These facts show that center pivot irrigation systems has not 
                         caused pressure on these areas, as long as the current legislation 
                         and government methodologies are applied.",
