First map of global freshwater trends shows "human fingerprint"

New research from NASA finds that human activities, including causing global warming and depleting groundwater for agriculture, are making for an increasingly water-stressed world. It's the first global accounting of trends in freshwater availability.

"No national, regional, or local water plan or assessment should overlook these estimates - they are the boundary conditions that shape water security."
