In 1964, it was the world's fourth largest lake. Thanks to irrigation projects, now it is mostly gone.

A Soviet-era plan to turn the arid plains of Kazakhstan, Uzbekistan, and Turkmenistan into fertile cropland resulted in the near-total diversion of the water that once fed the Aral Sea. Prior to the scheme, two rivers—the Amudar’ya in the south and the Syrdar’ya in the north—flowed out of distant mountains and pooled in a desert basin in what is now southern Kazakhstan and northern Uzbekistan. The irrigation project began in the mid-1900s, and by 1960, the sea had already begun to dry out.

stronauts aboard the International Space Station (ISS) took this image of a major dust storm (image center and right) along the east side of the Aral Sea while passing over central Asia in the spring of 2007. The white, irregular lines along the bottom of the image are salt and clay deposits on the present coastline. The day that the ISS crew shot the image, winds were blowing from the west (lower left).

The Aral Sea has shrunk to less than half its size since 1985. It receives little water (sometimes none) from the two major rivers that empty into it—the Syr Darya and Amu Darya. Instead, the river water is diverted to support irrigation for the region’s extensive cotton fields. Recently, water scarcity has increased due to a prolonged drought in Central Asia. As the Aral Sea recedes, its former seabed is exposed. The Aral’s sea bed is composed of fine sediments—including fertilizers and other agricultural chemicals—that are easily picked up by the region’s strong winds, creating thick dust storms. The International Space Station crew observed and recorded a large dust storm blowing eastward from the Aral Sea in late June 2001. This image illustrates the strong coupling between human activities (water diversions and irrigation), and rapidly changing land, sea and atmospheric processes—the winds blow across the Sea and pick up dust (former sea bottom sediments) as soon as the blowing air masses hit land.

Though the Aral Sea has been steadily shrinking over the past decade, this true-color image from August 2010 shows slight growth in the southern sea as water flowed into it from the Amu Darya for the first time since 2008.

Once the world’s fourth largest lake, the rapidly shrinking Aral Sea has fragmented into four bodies of water. The Southern Aral Sea and Tsche-Bas Gulf show the most dramatic change in 2011.
