Abstract:
The 21st century is said to be the water century. People living in regions having arid and semi-arid climate conditions are particularly concerned that water will become a severe constraint on their economic growth. The ‘dry-up in the Yellow River’ is one of most representative phenomena of water issues in the world. It is believed that increases in water demand associated with rapid socio-economic development and a decrease in water resources will lead to severe water shortages in the Yellow River Basin. However, the causes of the water shortages, especially the relationship between socio-economic conditions and water demand and the spatial distributions of water demand supply structures, have not been fully understood. Thus, this study aims to clarify the relationship between the socio-economy and water demand and to understand the spatial water demand and supply structures in the Yellow River Basin.
