Appraisal of Water Security in Asia: The Pentagonal Framework for Efficient Water Resource Management

Abstract

Swathes of global water challenges, such as water shortages, water pollution, water-related disasters, and degradation of water environments, have seriously threatened human development. The discussion of water security or insecurity has been instrumental in drawing the attention of political leaders thanks to its political nature and strategic and urgent messages for society to take action. This study introduces a modified concept and definition of water security and a water security assessment framework based on a review of previous works on water security; the water security framework intends to shed light on five core areas: (1) social equity; (2) economic efficiency; (3) environmental sustainability; (4) resilience to water-related disasters; and (5) government competency. A total of 28 countries in Asia and the Pacific have been chosen and appraised for their level of water security. The assessment result unveils that Japan, Malaysia, and South Korea show high levels of water security. In contrast, India, Pakistan, and the Philippines are regarded as the countries with water insecurity. The magnitude of the study lies in critically assessing good or challenging aspects of water security so that the countries can start to consider possible policy options for achieving sustainable water resource management.
