Abstract:

In this study the entropy method was adopted to calculate the indicator weights of the water security indicator system and the water security status of the 47 countries in the Asia-Pacific region were then assessed. National water security consists of 5 dimensions—household water security, economic water security, urban water security, environmental water security, and resilience to water-related disasters. The regional disparity of household water security is most significant, while the minimum value of regional disparity is found in resilience to water-related disasters. Regional economic water security is relatively satisfactory in Asia-Pacific; however, compared to other dimensions, resilience to water-related disasters is less satisfactory. The assessment reveals the actual water security status of countries and the result indicates that Australia, New-Zealand, and Malaysia are the most favorable countries in terms of national water security, but Kiribati is the worst country; countries in East Asia and the Pacific are in a much better condition than those in South Asia, Southeast Asia, and Central-West Asia. The overall water security situation in Asia and the Pacific region urgently needs improvement.

Key words: water security, assessment indicator system, entropy weight, Asia-Pacific
