- Abstract
This work aimed to map the central pivot irrigation systems in the state of Tocantins and through spatial analysis and field checking, identifying the area and types of crops under irrigation, such information can contribute to the development of public policies focused on the expansion of irrigation in the state. A total of 143 central pivots were identified, occupying an area of 14,555 ha. Through the field checking, we verified the existence of six types of irrigated agricultural crops distributed in 24 municipalities in the state of Tocantins, as follows: grains (6,053 ha, 42%); sugar cane (5,829 ha, 40%); pastures (2,056 ha, 14%); others (green corn, research and/or crop breeding) (227 ha, 2%); grass (216 ha, 1%), and pineapple (172 ha, 1%). The area of central pivots identified in this work represents 9.37% of the current irrigated area of the state, which matches between 0.8% and 1.54% of the area amenable to the development of sustainable irrigated agriculture identified in recent studies conducted by the National Water and Sanitation Agency.
