It is impossible to understand the developmental constraints of Africa without grasping the significance of water resources, particularly groundwater. Southern Africa faces potentially severe groundwater shortages, which not only imperil the lives of those directly dependent on it, but also the continued development of the economic engines of the region—South Africa, Botswana, Namibia, and Zimbabwe—all of which face significant constraints on their future economic growth due to the insecurity of water supply. In addition, groundwater resources are the foundation of rural water supplies, which sustain livelihoods for the poorest of the poor communities.
