3 Takeaways From CEWP’s 2019 Groundwater Policy Dialogue

By Yuanchao Xu 19 August, 2019

CWR's Xu shares the latest on groundwater policies & tech from the forum in Jinan

Groundwater management is key in China's regulatory framework for water management; 21 provinces suffer from over-exploitation of which Northern China accounts for 99%
Economics matter to water saving policies - experts say a high transferred water price may lead to groundwater over-exploitation elsewhere & a water quotas are more efficient than price control
New surveying & monitoring tech like SkyTEM could also help improve groundwater management; other topics were raised e.g. urban water consumption of 100L/px/day was seen as a realistic target

On 29 June 2019, the Rural Water and Food Security department of the China Europe Water Platform (CEWP) held the Groundwater Policy Dialogue on Water Saving Groundwater Quantity Management in Jinan, Shandong Province.

Attendees were a mix of experts including senior officials from China’s Ministry of Water Resources (MWR), Shandong County staff and overseas scholars. Through presentations (including China Water Risk) and lively discussions, the latest policies and ideas on groundwater were discussed. Topics ranged from policy to technology and public awareness to scientific development. Below are our three key takeaways.

1. Importance of groundwater management front & centre with actions on the way

Presentations from two MWR officials provided the overview of China’s current regulatory framework for water conservation and measures for groundwater protection and treatment.

The first MWR official, Dr. Jiangong Zhang  shared details on water saving policy systems and key actions for water conservation, such as the dual control of total amount used and the intensity of water use.

21 China provinces suffer from groundwater over-exploitation, of which Northern China accounts for 99%

The second MWR official, Dr. Yifan Huang  presented on China’s severe groundwater over-exploitation. According to Dr. Huang, 21 provinces in China are suffering from groundwater over-exploitation – to varying degrees – of which Northern China accounts for 99%

   

Dr. Huang also shared the main measures for groundwater protection and treatment being used in China now. Key points mentioned include:

  • The formulation of ‘The National Plan for Groundwater Utilisation and Protection’;
  • The delimitation of forbidden and restricted zones for groundwater exploitation;
  • Conduct the comprehensive governance of groundwater over-exploitation in North China;
  • Use economic approaches for groundwater protection;
  • Groundwater dynamic monitoring; and
  • The supervision and review scheme for groundwater management.

2. Economics key in optimising water saving policies

The economy runs on water (see our Big Picture for more). Thus, economic potential is strongly affected by the local water resources. Economic policies and pricing in turn impact water resources.  Water pricing is always a key factor in improving the water use mix, as well as the top concern for high water consuming industries.

Professor Fulin Li, Deputy Dean of Water Resources Research Institute of Shandong Province, spoke to his research on the industrial water pricing scheme of Zouping county in Shandong. The research provided the water price analysis based on different water sources and concluded that the high transferred water price (mainly from the Yellow river) may partly contribute to the high groundwater over-exploitation in Zouping.

CWR’s Yuanchao Xu was next up to speak on this topic. In addition to presenting on the impact of water on the economy and risk for investors, he dived into recent hot topics such as the trade war and the Jiangsu chemical plant explosion.

Dr Zhong from CAS, concluded that water quotas are a more efficient way to reach the 2030 water planning targets than price control

Dr Shuai Zhong from Chinese Academy of Sciences (CAS) then shared his research on quantity and price control mechanisms for optimising water saving policies. Importantly, using the Social Accounting Metric (SAM) and the Computable General Equilibrium with Dynamic Process (CGE), he concluded that the quantity control (water quotas) is a more efficient way to reach the 2030 water planning targets than price control.

3. New surveying & monitoring tools are improving groundwater management

Some overseas scientists have also shared their updates on the latest surveying and monitoring technologies and devices. Dr. Grombacher from Aarhus University presented new geophysical surveying tools: SkyTEM & Apsu, which are able to map hydrogeological structures and quantify land properties.

Yu Li from ETH Zürich introduced a red-line (Chinese three red lines policy, see more here) based decision support system for groundwater management and corresponding case study in Guantao, North China Plain.

Also, there is a new red-line (China’s Three Red Line policy) based decision support system

Apart from groundwater, other broader water saving topics were also discussed on the forum. Useful recommendations were drawn including:

  • Urban water consumption of 100 litres/person/day is a realistic target;
  • Awareness raising and education on the value and scarcity of water enhances acceptance of water saving measures at all ages and levels of society;
  • Managed aquifer recharge and improved quality of inter-basin transfers are efficient approaches to reduce groundwater recovery costs;
  • Water fee and tax collection is best done by outsourcing to the private sector etc.; and
  • Some field experiences have also shown that farmers’ cooperation is of great importance to water saving and monitoring systems.

All the suggestions from the forum will be compiled in the “Road to Recovery Part I Groundwater Quantity Management” (White Paper) and a corresponding policy brief will be presented at the 2019 CEWP Annual Conference 8 in November 2019 in Portugal.
