An April, 2018 Report by Charlie Parton, Special Advisor to the House of Commons Foreign Affairs Committee and a trustee of China Dialogue, a think-tank, points out that while average water resource availability is not serious by international standards,"8 northern provinces suffer from acute water scarcity, 4 from scarcity, and a further two (Xinjiang and Inner Mongolia) are largely desert. These 12 provinces account for 38% of China’s agriculture, 46% of its industry, 50% of its power generation (coal and nuclear use a lot of water), and 41% of its population."
"The government has discussed raising domestic water prices, but people use only 14% of China’s water. 62% is used in agriculture and 22% in industry/power generation, with 2% for other uses."
As China's freshwater resources have become polluted, addressing water and soil pollution is of paramount importance. However, rather than relying on increasing supply such as the South North Water Transfer Project (SNWTP), Parton suggests that the solution lies in better demand management. Click here

There is high wastage in water used in agriculture and industry, which account for 84% of total consumption. In addition to water pricing, increasing water use efficiency and reducing wastage may offer quicker and better solution than expanding supply.
This aspect is supported by a study by Sarah Rogers et.al. of the University of Melbourne, who, however, think that claims of a looming water crisis may be a little exaggerated. First, Chinese people's demand for potable water is much less compared with the West, where a great deal goes to gardening. Second, much of the water used in China can be recycled, as in Beijing, where groundwater levels are now showing signs of improvement rather than depletion. Nevertheless, such optimism is not shared by Charlie Parton, who subsequently filed a riposte.
In any case, both studies do not dispute that in the long term, water conservation and efficiency, water pricing, pollution containment, inter-basin transfers, new supply infrastructure, regional water trading platforms, and a near-national water grid are needed to prevent water availability from being a major constraint on China's economic trajectory.
