Middle East Water Loss
Is Starkly Documented by NASA Satellites
A pair of gravity-measuring NASA satellites has documented a precipitous drop in freshwater supplies in the arid Middle East
over the past decade. NASA said that since 2003 parts of Turkey, Syria, Iraq, and Iran had lost 144 cubic kilometers of total stored freshwater, an amount roughly equivalent to the water in the Dead Sea. NASA researchers attributed 60 percent of the loss to increased pumping of groundwater from underground reservoirs. An additional 20 percent of the loss came from soil drying up and snowpack shrinking, while the remaining 20 percent came from loss of surface water in lakes and reservoirs, according to the NASA study, to be published Friday in the journal Water Resources Research.
A drought in 2007 exacerbated all of these trends, but even without the drought scientists said that the rapidly growing population in the heart of the Middle East was using too much water at a time of increasing concern over intensifying droughts caused by climate change. The GRACE satellites — short for Gravity Recovery and Climate Experiment — measure changes in gravity
, in this case caused by the falling of water reserves, which alters the earth’s mass.
