Huge reserves of underground water in some of the driest parts of Africa could provide a buffer against the effects of climate change for years to come, scientists said.
Researchers from the British Geological Survey and University College London have for the first time mapped the aquifers, or groundwater, across the continent and the amount they hold.
‘The largest groundwater volumes are found in the large sedimentary aquifers in the North African countries Libya, Algeria, Egypt and Sudan,’ the scientists said in their paper.
They estimate that reserves of groundwater across the continent are 100 times the amount found on its surface, or 0.66 million cubic kilometres.

As the rest of the world starts running out of water, I think a new land grab by developed countries is going to start in Africa. Between its potential for solar energy and these water reservoirs plus the oodles of timber, labor, gems, and who knows what else, it’s only a matter of time. I wonder if I can find any similar maps of other continents to compare it too. Is it strange that largely desert Africa has such little low (< 0.1) aquifer productivity or does that just not happen often at all?
