- Abstract
Land use and land cover have changed significantly in recent years with population growth and the development of agriculture. To obtain increases in agricultural productivity, one of the most used technologies in Brazil and around the world is irrigation. This research identified the amount of equipment and areas equipped by center pivots in the Rio das Mortes River basin in the State of Mato Grosso, using satellite images of medium spatial resolution. The Rio das Mortes River basin is located in center-western Brazil, which is inserted in the Araguaia-Tocantins River basin. Landsat satellite images and the Google Earth Engine (GEE) platform were used. Normalized Difference Vegetation Index (NDVI) layers were constructed, and then the identification and quantification of the areas irrigated by center pivot in the study area were performed. The highest concentration of pivots in the Rio das Mortes River basin is in the subbasins of Primavera do Leste (213 pivots, 28 thousand hectares) and Poxoréu (31 pivots, 5 thousand hectares). The Rio das Mortes River basin in 2018 had 271 center pivots, occupying an irrigated area of approximately 36.5 thousand hectares.
