Sustainability Research Reveals Insights into Water Resource Utilization in China's South-North Water Diversion Project

Strategic Insights -

Researchers at the University of Melbourne have made significant contributions to the understanding of water resource utilization in China's South-North Water Diversion Project. By refining the category of water resource utilization, the study improved the index decomposition analysis, providing valuable insights into the spatiotemporal differences in water consumption in water-receiving areas. The research highlights the importance of implementing water-saving measures, developing advanced industrial structures, and optimizing water resource utilization in regions such as Henan, Hebei, Tianjin, and Beijing.

Key Takeaways:

  • The study improved the index decomposition analysis by refining the category of water resource utilization into water intensity, industrial structure, industrialization income, industry extraction, and population size.
  • The research constructed the logarithmic mean division index model and the multi-regional spatial decomposition models to simulate the spatiotemporal differences in water utilization in water-receiving areas.
  • The results indicate that the regional water-use intensity and the service industry extraction negatively influence water resource utilization, while the advanced industrial structure and industrialization income positively affected the increase in water resource utilization.
  • The study found that the Henan and Hebei water-receiving areas need to continue implementing water-saving measures, while Henan, Tianjin, and Beijing should explore the development of advanced industrial structures to optimize water resource utilization.
  • The research outcome is important in promoting the management, allocation, conservation, and circular utilization of water resources in the water-receiving area, leading to high-quality regional development.
  • The study suggests that the development of advanced industrial structures can positively affect the increase in water resource utilization, indicating a potential solution for regions facing water scarcity.
  • The research highlights the significance of considering the spatiotemporal differences in water consumption in water-receiving areas when managing water resources.

Statistics:

  • 6% of the Chinas' water resources are utilized in the South-North Water Diversion Project (Discover Sustainability, 2025).
  • 18% of the water resources in water-receiving areas are consumed by the service industry extraction (Discover Sustainability, 2025).
  • The Henan and Hebei water-receiving areas account for 30% of the total water resources utilized in the project (Discover Sustainability, 2025).
  • The study outcome is expected to promote the conservation and circular utilization of water resources in the region.
