Dust Blowing Over Sarygamysh Lake, Uzbekistan

Uzbekistan – June 16th, 2013

Significant desertification, characterized by degradation of the land and natural resources to the point that they can no longer be used, has been occurring in the region around the Aral Sea. A decline in the groundwater level in the deltas of the Amu Darya and Syr Darya rivers has contributed to the piling up of salt at the surface, resulting in the death of plants. The death of vegetation, in turn, has resulted in intensified winds, causing more dust storms in the area. Here, dust can be seen blowing across Sarygamysh Lake, in Uzbekistan, southwest of the Aral Sea.

Desertificatio and the Desiccated South Aral Sea

Aral Sea – April 1st, 2013

While water is present in the North Aral Sea, the South Aral Sea, which lies in poorer Uzbekistan, has been largely abandoned to its fate. Only excess water from the North Aral Sea is now periodically allowed to flow into the largely dried-up South Aral Sea through a sluice in the dike.

Discussions had been held on recreating a channel between the somewhat improved North and the desiccated South, along with uncertain wetland restoration plans throughout the region, but political will is lacking. Uzbekistan shows no interest in abandoning the Amu Darya river as an abundant source of cotton irrigation, and instead is moving toward oil exploration in the drying South Aral seabed.

Attempts to mitigate the effects of desertification include planting vegetation in the newly exposed seabed; however, intermittent flooding of the eastern basin is likely to prove problematic for any development. Redirecting what little flow there is from Amu Darya to the western basin may salvage fisheries there while relieving the flooding of the eastern basin.

Plume of Dust Near Amu Darya River

Afghanistan, Turkmenistan and Uzbekistan – February 28th, 2013

A plume of dust blows westward and then northward over the Amu Darya River, southeast of the Caspian Sea, in the border region of Afghanistan, Turkmenistan and Uzbekistan. Desertification has been a problem in this region, resulting in an increased frequency of dust storms.

Caspian Sea – December 13th, 2012

Plume of dust can be seen blowing westward over several bodies of water in this image of Kazakhstan, Uzbekistan and Turkmenistan (top to bottom). In the upper left quadrant, the dust blows over the northern section of the Caspian Sea. In the lower right quadrant, the dust blows over Sarygamysh Lake (right edge) and Karabogas Bay.

Kyzyl Kum Desert and Shrinking Aral Sea – October 12th, 2012

Aral Sea – October 9th, 2012

Visible in the upper left quadrant of this image is the shrinking Aral Sea, now separated into three basins. Here, water in the northern and southwestern basins appears greenish blue from phytoplankton growth, while the southeastern basin appears much shallower and drier, and is ringed by white salt flats.

South and east of the shrunken sea is the Kyzyl Kum, the 11th largest desert in the world. It is located in Central Asia in the doab between the rivers Amu Darya and Syr Darya, and is divided between Kazakhstan, Uzbekistan and Turkmenistan. It covers about 298,000 km2 (115,000 sq mi). The territory consists mainly of an extensive plain at an altitude up to 300 m (980 ft) above sea level, with a number of depressions and highlands. Most of the area is covered with sand-dunes.
