Moisture stress affects over two thirds of all soils in semi arid areas while soil fertility degradation has been described as the second most important constraint to food security in Africa. Despite proposals for a diversity of solutions and the investment of time and resources by a wide range of institutions it continues to prove a substantially intransigent problem. Inadequate management has exacerbated these problems to an alarming extent. The population is thus trapped in a vicious poverty cycle between land degradation, and the lack of resources or knowledge to generate adequate income and opportunities to overcome the degradation.
