| Abstract: | An overview of progress during the past 30 years in the hydrogeologic understanding of groundwater in hard-rock aquifers of tropical regions is presented. Geographically, the paper concentrates upon and contrasts Tropical Africa and Peninsular India, where very extensive areas of weathered hard-rock aquifers occur, but its conclusions are more widely applicable. This scientific understanding forms the basis for a critical discussion of key policy issues for the development and management of the water resources of these aquifers, given their major importance for economical and sustainable water-supply provision, in the context of efforts to achieve the UN Millennium Development Goals for rural drinking water and improved livelihoods. |
