             abstract = "The areas irrigated by center pivots in 1985, 1990, 1995, 2000, 
                         2005, 2010 and 2015 in the Region of MATOPIBA (Brazil) were 
                         digitalized through visual identification based on a mosaic formed 
                         by images of the satellite Landsat 4, 5, 7, and 8, displayed using 
                         the software Google Earth. There was a significant expansion of 
                         the area irrigated by center pivots in this period, that changed 
                         from 13 to 1,548 pivots between 1985 and 2015, when the irrigated 
                         area increased from 1,418 ha to 160,172 ha. More than half of the 
                         center pivots occurred in Microregion of Barreiras and Santa Maria 
                         da Vitoria, in the western part of the State of Bahia, in the 
                         Middle S{\~a}o Francisco River Basin. The municipalities with the 
                         highest density and relative area occupied by center pivots were: 
                         Barreiras / BA, Luis Eduardo Magalh{\~a}es / BA, S{\~a}o 
                         F{\'e}lix do Coribe / BA and S{\~a}o Desid{\'e}rio / BA. They 
                         were also the municipalities with the highest increase in area 
                         irrigated by center pivots considering the analyzed period. In the 
                         States of Tocantins, Piau{\'{\i}} and Maranh{\~a}o, the 
                         municipalities with the highest relative area occupied by center 
                         pivots were respectively Pedro Afonso / TO, Guadalupe / PI and 
                         Riach{\~a}o / MA. The region is considered of great interest to 
                         expansion of the agricultural frontier of Brazil. Environmental 
                         conservation should be considered for the future expansion of the 
                         irrigated area in the Region.",
