China's ambitious hopes for a "green" Beijing Olympics have magnified, not relieved, the city's reckless dependence on water from strained underground supplies and a mammoth canal project, a critical report says.
Beijing has promoted its 2008 Games as a nature-friendly festival of sport, but water for the expanses of greenery and sparkling waterways greeting visitors in August will be pumped from sources already battered by over-use and over-engineering, says Probe International, a Canada-based conservation group.
"With each new project to tap water somewhere else, demand for water only increases, and at an ever greater cost to China's environment and economy," says the group's report given to reporters on Thursday. "Whether diverting surface water or digging ever-deeper for groundwater, the underlying solution is like trying to quench thirst by drinking poison."
The Beijing Games have been beset by worries that air pollution will impair athletes. Yet Probe International's study suggests the Games' thirst for cheap and plentiful water will also leave an environmental burden.
Strained underground sources supply over two thirds of Beijing municipality's needs, and since 2004 the city has also begun drawing on "karst" groundwater supplies 1 km (0.62 miles) or deeper below the surface.
These deep underground sources, stored in porous rock, were originally set aside for use only in times of war and emergency, the report says. Beijing's thirst for water for the Games has also piled pressure on Hebei, the largely rural province next to the capital that supplies much of its water.
To ensure there was no risk of Beijing running short for the Games, officials ordered a 309-km (192-mile) northern section of the larger South-North Water Transfer Project first be completed to pump more water, if needed, from Hebei.
Hebei is already one of the country's most water-short provinces after a decade-long drought, but nonetheless supplies Beijing with about 80 percent of its water.
A visit there this week showed the canal project has been completed, but only barely, and many farmers have been left weighing the costs of giving up land, water and crops for the sake of presenting a verdant Olympic city.
"We've been lucky with the rains this year, but we still don't have enough water," said Liu Xiuge, a middle-aged farmer in Gaochang Village, who said farmers had planted corn, rather than wheat, because not enough water was available. Other villagers there said wells were running low because engineers had pumped away groundwater to make way for the canal, about 100 metres across, now cutting through the fields.
