Water Use Analysis and 2014 China’s Water Demand Forecast by Sector

In 2014, the agricultural water use efficiency of China will be promoted continually and mainly embodied by the improving of irrigation water use efficiency. It is explicitly stipulated in the Twelfth Five-year plan for national water resources development that national water consumption for every ten thousand Yuan of industrial value added should be reduced to 63 m³ by the end of Twelfth Five-year plan, which was 76 m³ in 2012 (at 2010 year price). It will show a slight decline in 2014. Water use efficiency in some highly water-consuming industries such as steel industry, paper industry, petrochemical and chemical industry, will be improved significantly. Mainly due to population growth and the improving living standards, the domestic water consumption will increase. With the strengthening of ecological environment construction, the ecological water demand in China will steadily increase.

Based on the above analysis, it is expected that the total water demand in China to be about 621.85 billion m3 in 2014. From the perspective of water use structure, agricultural water demand, industrial water demand, domestic water demand and ecological water demand is accounting for 60.9%, 23.9%, 13.4% and 1.8% of the total water demand respectively. The corresponding volume is expected to be about 378.5 billion m3, 148.5 billion m3, 83.3 billion m3 and 11.5 billion m3.

In the new period of reform, to strengthen the supporting capability of water resources for a steady and rapid economic development in the long run, the following policy suggestions were provided.

a) Encouraging the investment in water conservancy construction works, improving the efficiency of agricultural water use to the greatest extent by some effective measures like irrigating crops at the same ripe period together.

b) Paying more attention to reclaimed water use and other sources of water, encouraging suitable water being properly used.

c) Popularizing the use of water-saving technology and instruments.

d) Restricting the luxurious water use.

e) Stressing the supervision and inspection of water quality so as to reduce water pollution.
