New study on sustainable water management in Northern China

The Ziya River is formed by rain falling in the Taihang Mountains. On its way to the Bohai Gulf it crosses the North China Plain, a hotspot for economic development and an important bread basket for China. Water is a very scarce resource in this region and the high agricultural production is sustained by over-exploitation of the groundwater aquifer. Every year people pump groundwater from an even greater depth to satisfy their demands for water.


In a new research project, a decision support tool has been developed. This tool can guide managers to the long term cheapest sustainable water policy and can also be used to estimate the benefits of e.g. investments in new water infrastructure or water saving initiatives. The study analysed the economic impact of the South-to-North Water Transfer Project along with the societal cost of introducing a minimum ecosystem flow constraint.
