The new aral

In the early ’60s, the government of the Soviet Union decided to divert the water of the two rivers (Syr Darya and Amu Darya) that flowed into the lake, using canals, in an attempt to irrigate the desert to cultivate rice, melons, cereals, and to water the vast new cotton fields in the surrounding areas. This was part of the intensive cotton cultivation plan promoted by the Soviet regime, aimed at making Russia one of the major exporters. The construction of irrigation canals began on a large scale in the 1940s. Most of them were built hastily, allowing water to leak or evaporate.
From 1960 to 1998, the lake’s surface had decreased by about 60%, and its volume by 80%. In 1960, the Aral Sea was the fourth-largest lake in the world, with a surface area of 68,000 km² and a volume of 1,100 km³, whereas by 1998 the surface had shrunk to 28,687 km². During the same period, salinity increased from 10 to 45 g/l. Since 1987, the lake has split into two separate bodies of water, the North and South Aral Sea, due to the continued water withdrawal. By 2004, the Aral Sea’s surface had shrunk to only 17,160 km², 25% of its original extent, while salinity had increased nearly fivefold, killing most of the flora and fauna.
By 2007, the lake’s surface had further declined to 10% of its original size. The retreat of the North Aral Sea has been partially reversed thanks to the construction of a dam, but the remains of the South Aral Sea continue to disappear.
