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.
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.
Acquired March 26, 2010, this natural-color image shows a plume rising from the eastern lobe of the South Aral Sea. The dust blows toward the southeast, along the Kazakhstan-Uzbekistan border.
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).
large dust storm blew westward from the Aral Sea in late April 2008. Dry lake bed sediments provide plentiful material to be blown by dust storms, and such sediments surround the Aral Sea.
