Researchers have found that Africa has huge reserves of water underground, which they estimate are more than a hundred times the annual renewable freshwater resources.
Their findings, published in the academic journal Environment Research Letters, show that the largest reserves are in aquifers in the north African countries of Libya, Algeria, Egypt, Chad and Sudan.
The scientists used existing data, but for the first time this data was collated to give a continent-wide picture. They estimate that there are 0.66 million cubic kilometres of groundwater storage under Africa. →
