Researchers assess water security of Central Asian countries
TEXT SIZE: A A A

Located in the hub of the Silk Road, Central Asia belongs to arid and semi-arid region, and water resource is the most critical natural factor affecting the economic development and social stability of the region. Researchers from Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, analyzed the development and utilization of water resources, quantitatively assessed the four main water security sub-objectives and the comprehensive level of water security in five Central Asian countries. 

  

Researchers from the State Key Laboratory of Desert and Oasis Ecology of Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences,   established the assessment indicators system and classification standard data set of water security in Central Asian countries by using the projection pursuit model based on particle swarm optimization (PSO-PEE).

 

The research results indicated that: (1) For the ecological security, Kazakhstan, Tajikistan and Kyrgyzstan have improved their status, but Turkmenistan is getting worse; For the quantity security of water resources, Tajikistan and Kyrgyzstan are relatively safe, whereas Uzbekistan is at risk; For the socio-economic conditions, Kazakhstan scored the highest, while Tajikistan and Uzbekistan scored the lowest. (2) Water consumption per 10,000 dollars of GDP across all five Central Asian countries is relatively high but shows a significant decreasing trend, indicating that the water utilization efficiency in Central Asia is gradually improving. (3) For the water supply and demand security, the status of Kazakhstan, Kyrgyzstan and Tajikistan are better than that of Turkmenistan and Uzbekistan. (4) Kazakhstan has achieved a relatively safe level (level ) and the degree of water security is high. Kyrgyzstan, Tajikistan and Turkmenistan are only in the basically safe level (level III). Uzbekistan is under significant pressure with regard to water security (level IV).

 

Research results entitled Development and utilization of water resources and assessment of water security in Central Asia was published on the Agricultural Water Management.
