Aral Sea's Eastern Basin Has Gone Dry

In
a landmark moment that will go without celebration, the eastern basin of the
South Aral Sea has completely dried for the first time in modern history.
According to
NASA, the Central Asian lake has been
shrinking since the 1960s, when the Soviet
government began diverting water in the area for agriculture. However, the lake
hasn’t dried to such an extent until this summer.
"This is the
first time the eastern basin has completely dried in modern times," Philip
Micklin, a geographer emeritus from Western Michigan University and an Aral Sea
expert, told NASA. "And it is likely the first time it has completely
dried in 600 years, since Medieval desiccation associated with diversion of Amu
Darya to the Caspian Sea."
More than 60
million people now live in the Aral Region, and inflows to the lake have
dropped likely due to climate change.
This most recent
desiccation is a result of dwindling snow and rain that typically feeds the
lake, Micklin said. In addition to dwindling inflows, massive
irrigation efforts of the regions two major rivers, the Amu Darya and the Syr
Darya, depleted nearby water levels, according to
New Scientist.
What was once the
world’s fourth-largest lake is now split into several pieces: the
Northern and Southern Aral Seas, and further, the eastern and western lobes of
the larger Southern Aral Sea.
As Slate reports, the lake’s
gradual disappearance is making the region’s seasons more extreme.
The South Aral’s
eastern lobe almost completely dried in 2009 but made a comeback in 2010,
according to NASA.
