Short-term exploitation of African land and water may lead to long-term problems
from Physics Today
Countries such as China, India and Saudi Arabia have begun to lease well-watered land in Africa to grow food crops. Doing so is cheaper and easier than maintaining and improving the water resources back home. Two papers published in
Geophysics Research Letters
warn that leasing of African water sources could make the continent more vulnerable to market forces and the effects of climate change.
