		<abstract>Water is a key resource for human well-being, furthermore, essential for agricultural production systems and socioeconomic maintenance. In the Goiás 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 Goiás 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 São João da Paraúna 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.</abstract>
