Water in China Part III

This post will conclude the three part series of water in china. You can read part one here, and part two here. Most of this information is derived from Peter Gleick's publication titled "China and Water".

China is slowly starting to introduce water pricing to induce conservation. Such measures in water management have already been brought about in places like Guelph, Ontario. For a long time, water utilities have been subsidized by the Central government which has reduced the need to encourage water conservation. But now, with sustainable water management as a long-term national goal, Chinese cities are slowly implementing water pricing. In Beijing, price for domestic water use have more than doubled 4 yuan per cubic meter. For water intensive activities such as commercial car washing, it cost 45 yuan per cubic meter.

In Shenzhen (Southern China) local government officials have called for initiatives to recycle water, introduce rainwater harvesting and cut back on overall water use. Price-driven quotas are being introduced in Southern China, which means that urban homes that use more than 210 lcd (Canadians use about 343 lcd) will have to pay a surcharge on additional use. The more you consume past the 210 maximum, the more you pay for.

Separate quotas are being imposed on the various water users which includes industrial, agriculture, residential and commercial. The key point is that local governments in Southern China (where water is more abundant) are adopting flexible pricing systems based on different water users; this is an important step because the industrial and agriculture sectors use lots of water and constitute a greater share of GDP output. The greatest cuts need to happen in the residential sector; but this can only happen with education and good incentives to use less. Moreover, Northern cities should follow Beijing's initiatives and adopt smarter pricing systems. Northern cities have less water than southern ones yet they are slower to bring about water management initiatives. Reducing national water use requires participation from each city.

According to Peter Gleick, China has invariably experienced poor public participation grades for water projects and water policy. The Three Gorges Dam is notorious for its non-existent public consultation process which led to the displacement of 1.3 million people. Gleick writes:

“A major environmental law passed in China in 2003 for the first time ostensibly encouraged public participation in environmental decision making. This law, the Environmental Impact Assessment (EIA) Law requires all major construction projects to undertake an impact assessment". Further, it states “The nation encourages relevant units, experts and the public to participate in the EIA process in appropriate ways”. In addition, the law states that “the institutions should seriously consider the opinions of the relevant units, experts and the public” and “should attach explanations for adopting or not adopting the opinions".

Sounds like a well thought out law; however, its effectiveness is questionable. Some citizens have taken many matters into their own hands; some have sued chemical plants to force compensation for health and environmental damages (due to polluted water supply) or to make more environmental information accessible to the public. With China's explosive growth -- in economy and population -- and with the indispensable role water plays for economic growth –through dams, wastewater, agriculture, irrigation and forthcoming desalination—it is clear that it is a extremely valuable resource that will shape China’s future.

With sensible pricing structures being introduced, and with wastewater treatment plants helping provide cleaner water, the test for China will be whether it can engage more of its citizens in an equitable and efficient manner. Public participation should not be viewed as a hindrance to dam construction; citizens are demanding that such construction be built in a way that minimizes harm to their livelihoods and that effective compensation measures are in place for those affected by it.

As Gleick says “Sustainable water management has long taken a backseat to the Chinese for economic growth. With supplies dwindling, the Chinese will start conserving it through pricing and through desalination construction" (which is problematic but necessary considering China’s population).

Patricia Adams, an executive director of Probe International says that cities like Beijing can't keep going further with larger engineering projects to take water from other peoples' watersheds. "Beijing needs to implement regulatory and pricing regimes that reflect the scarcity of water in their own watershed and induce conservation and watershed rehabilitation". Clearly, the country needs some sort of water education program to inform people not only about conservation but about the impact of certain chemicals and contaminants to reduce health impacts from exposure.

Key message: If China truly wants to achieve sustainable water management, it will need to ensure that its central governments puts pressure on local governments to develop the legal, technological, and institutional tools to clean up water pollution, reduce wasteful and inefficient uses of water, restore natural ecosystems, and develop sustainable sources of supply.

** China is spending 500 billion yuan (77 billion Canadian) on the South-North Water Diversion Project. It will be completed by 2050 and is the largest scheme of its type in the world. It will divert about 44.8 billion cubic meters of water per year from various rivers. Hopefully, this project is accompanied with extensive water conservation education and with water pricing systems. You can read about this project here.
