Climate change ultimately caused the demise of Transoxania

Climate change doomed the ancient Transoxania civilization, suggests a new study. 

An international team of scientists analyzed sediment samples from rivers and now abandoned canals in the area where this ancient civilization once lived. Their research published in the Proceedings of the National Academy of Sciences suggests that climate change led to the ultimate fall of the Transoxania civilization.

Transoxania or Transoxiana is the ancient name of the portion of Central Asia corresponding to modern-day southern Kyrgyzstan, Uzbekistan, and Tajikistan. Geographically the region is situated between the Amu Darya and Syr Darya rivers. Earlier research has suggested that the Mongolian invasion of Transoxania in the 13th century caused the civilization’s demise.  

In this new research, the researchers analyzed ancient sediment samples from the dry canals used by the people of Transoxania to corral floodwater from Amy Darya and Syr Darya rivers and used it for irrigation.

Optically stimulated luminescence tests and radiometric dating provided the time period when these canals were abandoned. A similar test conducted on the sediments from the Amy Darya and the Syr Darya rivers suggested a change in river flow during that period. 

The changing river flow impacted the agriculture and livelihood of the Transoxania people. Drought before and during the Mongolian invasion made it difficult for the people to defend and recover after the Mongols left. Research showed that rains followed the invasion but were not enough to sustain a livelihood, and the people eventually moved on to more hospitable regions.
