Image Caption: Agricultural patterns are distinctly visible in this near-vertical false color infrared photograph (fig. 7). The area depicted on the photograph is south of Khartoum between the White and Blue Nile Rivers. By far the most important irrigation project in sub-Saharan Africa, both large and small scale agricultural enterprises have been developed using water transported from the perennial Nile Rivers. Hundreds of small rectangular fields and water-filled canals can be seen in this photograph. Throughout the year one half of the fields will be in crops and the other half will be fallow. This rotation system is for resting the soil and for pest control. The major crops grown in this region include cotton, durra, and millet.
