Introduction

With increasing hydro-climatic risks in Africa all water resources will be affected (Vorosmarty et al. 2010; IPCC 2012). But the response to climate variability of groundwater will be slower than that of surface water. Groundwater resources are more resilient due to aquifer storage which acts as a buffer during periods of little or no rainfall. Despite the significant availability of groundwater resources across the major geological formations in Africa, the quantitative and qualitative distribution remains partly understood (MacDonald et al. 2012). Adapting to environmental change will likely require increasing use of groundwater for both domestic and productive uses. Information costs in recording longitudinal data on aquifer recharge and use are prohibitively high and point estimates from a limited sample of verifiable drilling sites provides partial information on whether shifting patterns of groundwater availability are attributable to environmental or operational fact ...
