ABSTRACT
The importance of Lancang-Mekong River has concerned scholars, but existing research mostly analyzes water utilization from a macro level. However, due to the challenge of increasing scarce water resources, improving water use efficiency seems to be the effective solution to improve water imbalance between supply and demand and for sustainable use of water (Allan, 1999; Deason et al., 2001). Former EPA Administrator William Reilly points out that water use efficiency is not high in the world, and typically 50% of the water is wasted. The UK government ensures improvement of water use efficiency and reduction of water pollution to achieve both environmental protection and sustainable utilization of water resources. China’s Water Law clearly indicates the improvement in water use efficiency through reasonable water resource allocation of agricultural water, industrial water and domestic water.
