The objective is to make the book relevant for anywhere; where the rainfall is a big problem because of its quantity, distribution or unreliability. It outlines the scale and importance of the problem, difficulties and possibilities for the improvement. It strongly argues and presents evidences that drought is part of the natural order in semi-arid areas and that the recent disasters of degradation and famine in Africa result from misuse and mismanagement of the natural resources which reduced the region's ability to cope with the additional stress of drought.
