Another critical problem for Africa, particularly in sub-Saharan Africa is that of desertification. The crisis of desertification in the Sahel and other dryland regions of Africa increases exponentially, that is, its effects are incrementally debilitating. Each year of delay in dealing with this problem in an effective way, using available technology and resources, moves the problem further beyond our capacity to handle it. Furthermore, desertification has many direct and indirect effects on, among others, food production, land use, transport, housing, and weather patterns, further compounding the problem. The scale of the problem is enormous, and neither African governments nor international organizations organizations have mounted an effective response. The problem of desertification in Africa is, however, to a great extent, a tale of opportunities missed. The application of existing technology and resources has encountered obstacles and resistance, while potential resources have failed to materialize.
