The Aral Sea was an endorheic
lake (one with no outflow) lying between Kazakhstan
(Aktobe and Kyzylorda Regions) in the north and Uzbekistan (Karakalpakstan
autonomous region) in the south. The name roughly translates as "Sea of Islands ",
referring to over 1,100 islands that had dotted its waters; in the Turkic
languages aral means "island, archipelago". The Aral Sea drainage
basin encompasses Uzbekistan
and parts of Tajikistan , Turkmenistan , Kyrgyzstan ,
Kazakhstan , Afghanistan and Iran .

Formerly one of the four largest lakes in the world with an area of 68,000 km2 (26,300 sq mi), theAral
Sea has been shrinking since the 1960s after the rivers that fed
it were diverted by Soviet irrigation projects. By 1997, it had declined to 10%
of its original size, splitting into four lakes – the North Aral Sea, the
eastern and western basins of the once far larger South Aral Sea, and one
smaller intermediate lake. By 2009, the southeastern lake had disappeared and
the southwestern lake had retreated to a thin strip at the western edge of the
former southern sea; in subsequent years, occasional water flows have led to
the southeastern lake sometimes being replenished to a small degree. Satellite
images taken by NASA in August 2014 revealed that for the first time in modern
history the eastern basin of the Aral Sea had
completely dried up. The eastern basin is now called the Aralkum Desert .
In an ongoing effort in Kazakhstan to save and replenish the North Aral Sea, a dam project was completed in 2005; in 2008, the water level in this lake had risen by 12 m (39 ft) compared to 2003. Salinity has dropped, and fish are again found in sufficient numbers for some fishing to be viable. The maximum depth of theNorth Aral Sea is 42 m (138 ft) (as of 2008.)
The shrinking of theAral Sea has been called "one of the planet's worst
environmental disasters". The region's once-prosperous fishing industry
has been essentially destroyed, bringing unemployment and economic hardship.
The water from the diverted Syr Darya river is used to irrigate about 5 million
acres (2 million hectares) of farmland in the Ferghana Valley .
The Aral Sea region is also heavily polluted,
with consequential serious public health problems.
UNESCO added the historical documents concerning the development of theAral Sea
to its Memory of the World Register as a unique resource to study this
"environmental tragedy".
