UN scientists warn of increased groundwater demands due to climate change
March 12, 2012 Climate change has been studied extensively, but a new body of research guided by a San Francisco State University hydrologist looks beneath the surface of the phenomenon and finds that climate change will put particular strain on one of our most important natural resources: groundwater.
SF State Assistant Professor of Geosciences Jason Gurdak says that as precipitation becomes less frequent due to climate change, lake and reservoir levels will drop and people will increasingly turn to groundwater foragricultural, industrial, and drinking water needs.
The resource accounts for nearly half of all drinking water worldwide, but recharges at a much slower rate than aboveground water sources and in many cases is nonrenewable.
"It is clear that groundwater will play a critical role in society's adaption to climate change," said Gurdak, who co-led a United Nations-sponsored group of scientists who are now urging policymakers to increase regulations and conservation measures on nonrenewable groundwater.
