Region, east-central Sudan.
Southeast of the confluence of the Blue Nile and the White Nile rivers, it is the site of one of the largest irrigation projects in the world. Begun by the British in 1925, the project distributes the waters of the Blue Nile through a 2,700-mi (4,300-km) network of canals and ditches. It has made the region the most productive agricultural area of The Sudan.
