- Abstract
Irrigated agriculture in Brazil has grown over 40% in the last 20 years, representing an area of 4.4 million ha, with the Southeast region representing 47% of this total. The pivot irrigation method is the fastest growing, with the states of Minas Gerais, Goiás, Bahia and São Paulo concentrating around 80% of the area occupied by technology. In this scenario, updating the information becomes fundamental because it will create knowledge bases that will help establish guidelines for the adoption and planning of public policies that will contribute to the strategic use of water resources. It was realized photointerpretation in scale of 1: 1000, in satellite images of the platform Google EarthTM Pro, for identification of the equipment and obtaining of its area of occupation. With the data collected, analyzes were performed according to the municipalities, microregions and river basins. Currently, an irrigated area of 134,741.11 hectares and 2,301 central pivots is estimated. The municipalities of Rio Paranaíba (302), Perdizes (164), Santa Juliana (135), Uberaba (120) and Patos de Minas (111) stand out in more equipment. The Araxá Microregion encompasses the highest concentration of pivots, 694, with 40,728.94 irrigated hectares. In the Paranaíba River Basin, 85.75% of the pivots are concentrated.
