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. The study, published in Discover Sustainability, decomposed the index of water consumption in water-receiving areas into five categories, including water intensity, industrial structure, industrialization income, industry extraction, and population size. The researchers found that advanced industrial structures and industrialization income positively affected water resource utilization, while regional water-use intensity and service industry extraction negatively influenced it.

Key Takeaways:

  • The study improved the index decomposition analysis by refining the category of water resource utilization into five sub-categories.
  • The logarithmic mean division index model and multi-regional spatial decomposition models were used to simulate the spatiotemporal differences in water utilization in water-receiving areas.
  • The results indicated that regional water-use intensity and service industry extraction negatively influenced water resource utilization, while advanced industrial structures and industrialization income positively affected it.
  • The increase in water resource utilization varied in each study area due to the hierarchy of water usage priority.
  • The research suggested that Henan and Hebei water-receiving areas need to continue implementing water-saving measures, and Henan, Tianjin, and Beijing should explore the development of advanced industrial structures to optimize water resource utilization.
  • The study 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.
