CHINA: THE WATER CRISISKeshav Kohli
The Triple Threat Flooding (South) Water Shortages
(North) Contamination by
industrial pollution
Severe pollution of Tai Lake in eastern China’s Jiangsu providence.
A Growing Demand
The breakdown: 78% Agricultural 18% Industry 5% Domestic
Domestic Demand
Household Consumption
Public Consumption
Livestock
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
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%
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.
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)

Jianfa Shen: The Rural-Urban Population Shift
Possible Causes
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
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
