China’s South‐to‐North Water Transfer Project: Is it Needed?

Abstract

AbstractChina has started the construction of the South‐to‐North Water Transfer Project (SNWTP; its magnitude is even greater than the Three Gorges Dam Project), to deliver about 45 billion m3 of water from the Yangtze River to the water starving North China Plain. Is the project needed given the multiple socioeconomic, engineering, and environmental challenges and controversies it is facing and the effects of demand management programs China has been implementing in recent years? This article, through the analysis of the water shortage problems in the North China Plain and the Yellow River basin, demonstrates that considering China’s current economic base, technological capacity, and income levels, the SNWTP, while facing multiple challenges, is still needed to relieve the water deficit problems in the North China Plain. However, the SNWTP is only a partial solution to North China’s chronic water shortage problem. China should continue to actively implement and enforce its demand management programs nationwide to ensure that its limited fresh water resources are used to meet the multiple needs of human societies and ecosystems in a socially responsible, economically viable, and environmentally sustainable way.
