The Aral Sea (Kazakh: Арал Теңізі Aral Teñizi; Uzbek: Orol Dengizi; Russian: Аральскοе Мοре Aral'skoye More; Tajik: Баҳри Арал Bahri Aral; Persian: دریاچه خوارزم Daryocha-i Khorazm) is a saline endorheic basin in Central Asia; it lies between Kazakhstan (Aktobe and Kyzylorda provinces) in the north and Karakalpakstan, an autonomous region of Uzbekistan, in the south. The name roughly translates as "Sea of Islands", referring to more than 1,500 islands that once dotted its waters.

Formerly one of the four largest lakes in the world with an area of 68,000 square kilometres (26,300 sq mi), the Aral Sea has been steadily shrinking since the 1960s after the rivers that fed it were diverted by Soviet Union irrigation projects. By 2007 it had declined to 10% of its original size, splitting into four lakes – the North Aral Sea and the eastern and western basins of the once far larger South Aral Sea and one smaller lake between North and South Aral Sea.[3] By 2009, the south-eastern lake had disappeared and the south-western lake retreated to a thin strip at the extreme west of the former southern sea.[4] The maximum depth of the North Aral Sea is 42 m (138 ft) (as of 2008).[1]

The region's once prosperous fishing industry has been virtually destroyed, bringing unemployment and economic hardship. The Aral Sea region is also heavily polluted, with consequent serious public health problems. The retreat of the sea has reportedly also caused local climate change, with summers becoming hotter and drier, and winters colder and longer.[5]

There is now an ongoing effort in Kazakhstan to save and replenish the North Aral Sea. As part of this effort, a dam project was completed in 2005; in 2008, the water level in this lake had risen by 24 m (79 ft) from its lowest level in 2007.[citation needed][6] Salinity has dropped, and fish are again found in sufficient numbers for some fishing to be viable. However, the outlook for the remnants of the South Aral Sea remains bleak. The shrinking of the Aral Sea has been called "one of the planet's worst environmental disasters".[7]
