‘Huge’ water resource exists under Africa
Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater.
They 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.
Writing in the journal Environmental Research Letters, they stress that large scale drilling might not be the best way of increasing water supplies.
Across Africa more than 300 million people are said not to have access to safe drinking water.
Demand for water is set to grow markedly in coming decades due to population growth and the need for irrigation to grow crops.
Freshwater rivers and lakes are subject to seasonal floods and droughts that can limit their availability for people and for agriculture. At present only 5% of arable land is irrigated …
Due to changes in climate that have turned the Sahara into a desert over centuries many of the aquifers underneath were last filled with water over 5,000 years ago.
The scientists collated their information from existing hydro-geological maps from national governments as well as 283 aquifer studies.
The researchers say their new maps indicate that many countries currently designated as “water scarce” have substantial groundwater reserves.
However, the scientists are cautious about the best way of accessing these hidden resources. They suggest that widespread drilling of large boreholes might not work …

oh, shit. no wonder the recolonization of africa is pumping full steam ahead.

Oil, water and land…you know I am starting to be reminded of that crappy movie 2012 now.

Jesus,
Besides everything said above about colonialism (which is spot-on) -
Don’t start using up aquifers if it’s avoidable. Groundwater is not really a renewable resource. Tread f***ing carefully. Water is life.
-Someone who knows.
PS - and this means ESPECIALLY don’t f*** with *other people’s* Groundwater.
