Irrigation is important in the context of food, since each irrigated hectare is equivalent to 3-ha of irrigation in physical productivity and 7-ha in economic productivity. Given this importance and the fact that Brazil has different water availability from other countries, there was an approach to irrigated agriculture in the country, considering the irrigated area at the regional and state based on 2006 Census of Agriculture. Brazil has currently an area of 4.45 million hectares cultivated with irrigation being the largest irrigating the Southeast Region, followed by the South, Northeast, Midwest and Northeast. Among the crops, sugar cane, rice, soyabeans and maize stand out in irrigated area. The irrigation method used is more for sprinkling (no pivot), followed by flood, centre pivot, and located in the groove.
