Irrigation in Brazil has been developed through the use of different models. Public involvement in irrigation is relatively new while private investment has traditionally been responsible for irrigation development. Private irrigation predominates in the populated South, Southeast, and Center-West regions with most of the country’s agricultural and industrial development. In the Northeast region, investments made by the public sector seek to stimulate regional development in an area prone to droughts and with serious social problems. These different approaches have resulted in diverse outcomes. Of the 120 million hectares (ha) that are potentially available for agriculture, only about 3.5 million ha are under irrigation, although estimates show that 29 million ha are suitable for this practice.
