Economists rarely agree, an inexact science is a lush pasture to graze in. Let’s consider a fact though; the Chinese water management system encourages waste and exacerbates ecological damage. This is not a ground-breaking observation, Elizabeth Economy of the Council on Foreign Relations
(among others)has written extensively on the problem of dwindling supplies, unchecked pollution and inefficient use of water resources across all sectors of the economy.
The Chinese government are rightly concerned about the issue and plan to divert huge volumes of water from the relatively abundant South to the parched North over the coming years. Whilst it can be said that the Chinese love a big project, it doesn’t seem clear how this will address a very real problem.
Whilst there are many dimensions to the management of scarce water resources, getting the economics right is key. Water prices have been kept low to support both low-income families and industrial and agricultural sectors. Low revenues have, in turn, resulted in a lack of investment in distribution networks and water treatment to the detriment of water quality and conservation.
Whilst the Taihu Lake and Khabarovsk incidents have caught the headlines and shone a light on water mismanagement in recent years, an exhaustive study by the World Bank
has demolished the above social arguments. Subsidized prices do not protect lower income groups, and in many cases the benefits of subsidized tariffs unfairly accrue to financially secure members of society. In Chongqing , households with a monthly income of over 10,000 RMB enjoy a subsidy of 22RMB per month compared to a 3-4 RMB subsidy for households with a monthly income of 500 RMB or less.
Industrial and agricultural users have been found guilty of excessive and inefficient consumption in the past. Users in such industries as paper and textiles are renowned for their water intensive practices and disregard for environmental standards. According to Yuan Zhou of the International Earth Systems Research School , the Chinese agricultural sector uses twice the amount of water used in other countries to produce staple crops. Leaky distribution networks and inefficient irrigation practices are .
The practice of ‘getting prices right’ is a firm favourite in economic policy, it is not, however, a panacea. Investment in water management capacity (distribution networks, treatment facilities, recycling, pollution clean-ups etc) requires funding and a fair amount of political will. Subsidies need to be better targeted to help the most needy. Government action can only go so far, individuals need to be persuaded to ration consumption. The best way to do this is to start to charge a fair price.
