The Triple Threat Flooding (South) Water Shortages (North) Contamination by industrial pollution Severe pollution of Tai Lake in eastern China’s Jiangsu providence.
3
A Growing Demand The breakdown: 78% Agricultural 18% Industry 5% Domestic
4
Domestic Demand Household Consumption Public Consumption Livestock
5
Industrial Demand Southeast, Yangtze, and Peal Basins in the south require more than 75% of the total industrial water demand. Economic reforms of the 1970’s and 1980’s Food and beverage industries; power plants; mining facilities
6
Agricultural Demand Rain-fed Agricultural Uses Irrigated Agriculture: covers 56% of total arable land and provides 67% of China’s total grain output Cropping Intensities: Northern Basins: 135% Southern Basins: 200%
7
Water Shortages China has the same amount of water as Canada, but with a population 100 times greater (The World Resources Institute) Current policy failures in China's water management: underdeveloped system of water rights administration, weakness in water demand control, lack of market- based tools, and insufficient financing for pollution control. In short, lack of infrastructure.
8
Water Contamination Arsenic contamination of groundwater Spread of Algae Increased Industrialization Toxic spills 2006: 60% of China’s rivers cannot be used as drinking water resources (Magazine of the International Water Association)

10
Sewage Crisis and Contamination 1996: more than 20 billion tons of urban sewage was discharged into rivers, lakes, etc. Spitting on sidewalks contributes to sewage overflow In effect, drinking water does not meet governmental standards
11
So What? Health Related Effects: Liver and stomach cancer deaths have doubled since the 1970’s China has the highest liver cancer rate in the world Arsenic poisoning (Arsenic is a carcinogen) Economic Effects: Water scarcity in urban cities causes a loss of about $11.2 billion (120 billion yuan) in industrial output
