Cumulative Total Middle East/North Africa Freshwater Losses as Seen by NASA's GRACE, 2002-15

Dec. 8, 2015
Cumulative total freshwater losses in North Africa and the Middle East from 2002 to 2015 (in inches) observed by NASA's GRACE mission. Total water refers to all of the snow, surface water, soil water and groundwater combined.

Cumulative total freshwater losses in North Africa and the Middle East from 2002 to 2015 (in inches) observed by NASA's Gravity Recovery and Climate Experiment (GRACE) mission. Total water refers to all of the snow, surface water, soil water and groundwater combined. Groundwater depletion in Turkey, Syria, Iraq and Iran, and along the Arabian Peninsula, are leading to large changes in total water storage in the region. Likewise, drought and groundwater pumping is contributing to the drying of the Caspian Sea Region. The Northwest Sahara Aquifer System, which underlies Tunisia and Libya, is also experiencing increasing water stress as shown in the map. Image updated from Voss et al., 2013.
