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.

A plume of dust blows across the peninsula on the eastern shores of the Caspian Sea on which the city of Hazar, Turkmenistan, is located. A thinner veil of dust can also be seen over the Caspian Sea, Karabogas Bay (north of the peninsula) and Sarygamysh Lake (upper right).

Aral Sea – March 23rd, 2013

The region around the Aral Sea, whose water levels have dropped 23 meters since the onset of water diversion from its primary sources, has experienced significant desertification. The desertification is characterized by degradation of the land and natural resources to the point that they can no longer be used.

Several factors influence the desertification, including the decline in the groundwater level. By cutting off water supply to a region, the hydrological balance of the area becomes offset as more water leaves the region than is coming into the region.

Frequent low-water periods contributed to the shortfall of needed resources for vegetation. The decline in the groundwater level in the Amudarya and Syrdarya deltas contributed to the piling up of salt at the surface. This increase in salt content was later accompanied by a change in vegetative cover because the plants began to die away as a result of the increased salinity of the sea. As a result, vegetation in the region was reduced by at least 40%. Six million hectares of agricultural land were destroyed as a result of salinization and desertification (click here for more information).

A side effect of the decrease in the protective vegetation cover was intensified winds, which led to more dust storms in the area. Here, dust can be seen blowing across the southwestern basin of the lake and across the northern part of nearby Sarygamysh Lake.

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.

Turkmenistan - December 31st, 2011

The Sarygamysh Lake , Turkmen for ‘Yellow Depression,” is situated in north central Turkmenistan and visible in the lower left quadrant of this image. It is geographically located approximately midway between the Caspian Sea and the Aral Sea. Approximately the northwest quarter of the lake belongs to the country of Uzbekistan, while the rest belongs to Turkmenistan. Here, sediments line the northwestern shores.

To the east and northeast of the lake is the Syr Darya River, which rises in two headstreams in the Tian Shan Mountains in Kyrgyzstan and eastern Uzbekistan—the Naryn River and the Kara Darya—and flows for some 2,212 kilometres (1,374 mi) west and north-west Uzbekistan and southern Kazakhstan to the remains of the Aral Sea. The Syr Darya drains an area of over 800,000 square kilometres (310,000 sq mi). Along its course, the Syr Darya irrigates the most fertile cotton-growing region in the whole of Central Asia.
