Another reason for Ethiopia to tell Egypt to drill a well in the desert, or digg down into its pockets to pay for the precious Nile Water
Solutions to resolve the world’s water crisis may lay hidden underground. More than half the world’s population already depends on groundwater that is pumped from the pore spaces of rock formations, known as aquifers, which lie hidden below the Earth’s surface.
Scientists now say that Africa is sitting on a vast reservoir of groundwater.
Researchers from the British Geological Survey and University College London argue that the total volume of water in aquifers underground is 100 times the amount found on the surface.
The team have produced the most detailed map yet of the scale and potential of this hidden resource.
