Both climatic and non-climatic drivers such as socio-economic changes have created water stress conditions in both water supply and demand in all sub-regions of Asia, except for North Asia . These changes in space and time directly or indirectly have affected water-use sectors and services. By mid- 21st Century, the international transboundary river basins of Amu Darya, Indus, Ganges could face severe water scarcity challenges due to climatic variability and changes acting as stress multipliers . Due to global warming, Asian countries could experience an increase in drought conditions  by the end of this century .
