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.
