Action is urgently needed. More than 80% of African soil is seriously degraded, and in many areas it is on the verge of permanent failure. For centuries, farmers survived by clearing new land for each season's plantings and allowing old fields to lie fallow and replenish their nutrients.

But replenishing Africa's soil before it's too late--and thus decreasing the amount of land that has to be dedicated to agriculture--is probably one of the most practical ways of protecting wildlife habitats and reducing erosion. And new micro-dosing techniques, in which a capful of fertilizer is applied to the roots of a plant, minimize the flow of chemicals into rivers and streams...
