“Watershed Concept” — The Discovery Files

Scientists have developed a crop system that takes advantage of Guiera, a plant native to West Africa, to help sustain food supply for a growing population. A new study shows that the shrub, abundant in the Sahel region, can share the precious water they draw in and boost production of one of the primary grains, called millet, that provides nutrition to West Africans. The process can provide crop yields nine times greater than normal.
