Sun glint causes the White Nile River to appear truly white as it flows past the fields of the Gezira Scheme in Sudan. The Blue Nile borders this agricultural area to the east. The two rivers converge at Khartoum, near the top of the image.

The Gezira Scheme is one of the largest irrigation projects in the world, now covering about now covers 3,400 milesĀ² (8,800 kmĀ²) in the Sudanese state of Al Jazirah. It is composed of thousands of kilometers of canals that distribute water from the Blue Nile to farms between the two rivers.

The Gezira (which means “island”) is particularly suited to irrigation because the soil slopes away from the Blue Nile and water therefore naturally runs through the irrigation canals by gravity . The soil has a high clay content which keeps down losses from seepage. The main crop grown in this region is still cotton.
