Trends in Global Freshwater Availability

Data from the joint NASA/German Aerospace Center Gravity Recovery and Climate Experiment (GRACE) satellites help estimate trends in freshwater availability. These trends are associated with regional changes in precipitation, groundwater depletion, glacier and ice sheet melting, and other factors.

Changes in Freshwater Availability

Freshwater availability has decreased (orange) in the U.S. Southwest and Southern Great Plains due to drought and groundwater depletion, and in Alaska because of glacier melt. An increase in freshwater availability (blue) is seen in the Central U.S. as precipitation increased from 2002 to 2016.
