Description

 It is said that, in the 21st century, water scarcity has become a grave concern, especially in arid and semi-arid regions where climatic conditions impose a constraint on water resources. Such a severe constraint poses a threat to economical growth. Increase in water demand associated with rapid economic development exacerbates incidences of water shortage. Water shortage is not only an issue concerning arid and semi-arid regions but likewise affects developing countries and regions where the effects of climate change are significant. The objective of this study was to clarify the relationship between socio-economic growth and water demand and to estimate the fine spatial gaps in the demand and supply of water in China. Regional water demand from different sectors (agricultural, industrial, domestic) was estimated using a macro framework of socio-economic growth. Water supply from regional resources was estimated using observed meteorological data. Spatial gaps were found in the demand and supply of water using a 0.5 degree macroscopic mesh. Further, the amount of water flowing in both the Yellow River and the Chang River was estimated using a cascade-type water flow model.
