15. Water Conflicts (International Transboundary Water Conflicts- Restroing The Aral Sea) Flashcards
1
Q
Give 3 key years in the Aral Sea International Transboundary water conflict.
A
- 1987 - the sea split into two separate sections (the North Aral Sea and the South Aral Sea) as the water level decreased
- 2003 - the South Aral sea further divided into two, an eastern and western basin.
- 2004 - the Aral sea’s surface became 1/4 of its original size

Q
Why did the Aral Sea shrink?
A
- The Amu Darya river and the Syr Darya river were diverted to irrigate thirsty crops (e.g cotton) during the 1960s by the Soviet Union. - cotton still accounts for 17% of Uzbekistan exports
- Irrigation canals are leaky and suffer from high evaporation rates (30-75% of water wasted before used for farming)
4
Q
How much water goes to irrigation instead of reaching the Aral sea?
A
20-40km cubed
5
Q
Why was a plan to divert the rivers to refill the Aral Sea, which began in the 1960s, scrapped?
A
It was abandoned due to costs by 1986.
6
Q
Outline the key events in the Aral Sea International Transboundary water conflict.
A
- In 1997, Kyrgyzstan reduced the amount of flow leaving its Toktogul reservior and entering Uzbekistan
- Uzbekistan cut off 70% of the water flowing in to downstream Kazahkstan
- When the water crisis was reaching water stress, the 3 countries (Kyrgyzstan, Uzbekistan and Kazahkstan) started to negotiate and signed a barter agreement to share their water.
- In 2012, the Uzbek president announced plans to build two large hydroelectric dams in Tajikstan and Kyrgyzstan - potential for further conflict.

Q
How is the Aral Sea being restored?
A
In 1994, the Stan (Central Asian) countries adopted the Aral Sea Basin Programme.
8
Q
Give some examples of projects in the Aral Sea Basin Programme.
A
- The Kok-Aral Dam was built to store 29 cubic km of water but also to allow excess into the Aral Sea.
- The Kazakh Government built a dike to separate the North and South Aral Sea in 2005 - this has allowed the North Aral water level to rise, salinity to decrease and an increase in fish stocks (24 species returned)
- To support the dike, a second dam to support the water rise has been built with funding from the World Bank.
