Chinese Academy of Sciences
The Chinese Academy of Sciences is the linchpin of China's drive to explore and harness high technology and the natural sciences for the benefit of China and the world.

Central Asia belongs to arid and semi-arid region. Water resource is the most critical natural factor affecting the region.  

Researchers from the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences quantitatively assessed the four main water security sub-objectives and the comprehensive level of water security in five Central Asian countries, including Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan

They 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). 

Their results indicated that 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. 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. 

For the water supply and demand security, the status of Kazakhstan, Kyrgyzstan and Tajikistan are better than that of Turkmenistan and Uzbekistan.  

Kazakhstan has achieved a relatively safe level (level II) 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).
