The world’s largest underground aquifers are being depleted at alarming rates, according to new data from NASA. Ed Schultz discusses the findings with Jay Famiglietti, the senior water scientist at NASA's Jet Propulsion Laboratory.
A newly discovered water source in Namibia could have a major impact on development in the driest country in sub-Saharan Africa.
Estimates suggest the aquifer could supply the north of the country for 400 years at current rates of consumption. Scientists say the water is up to 10,000 years old but is cleaner to drink than many modern sources.
However, there are concerns that unauthorised drilling could threaten the new supply.
