Africa: Africa may struggle to extract groundwater, experts say

Vast groundwater resources have been revealed in Africa by the first continent-wide quantitative maps. But the resources may not be easily accessible because of political and technical challenges and costs, say experts. The new groundwater maps, published last month (19 April) in Environmental Research Letters, are based on an extensive review of available maps, publications and data. They show the continent has a total underground water storage capacity of 0.66 million cubic kilometres - more than 20 times the freshwater storage capacity of lakes on the continent.
