China's recently published "water census" shows that as many as 28,000 rivers have vanished from the country since the 1990s. It's a trend, the report suggests, that's likely to continue. But the causes of this problem are a little murkier. The "census" offers no reason for the disappearance of so many water sources.
In some places, like Minqin, where the Shiyang River has run dry, Beijing insists that climate change is to blame. Residents disagree. The government built a sizable upstream reservoir nearby two decades ago to irrigate a large farm. That cut off the water supply for residents.
Regions like Gansu, where Minqin is located, are some of the country's driest. And the government tends to rely on big projects like giant dams and diversion channels to address its water problems. Desperate for growth, officials are, in some cases, choosing between water and electricity.
"China is looking always at mega-projects rather than addressing the root causes," Zhou Lei, a fellow at Nanjing University who studies the affects of industry on the environment, tells Reuters. "They experiment with technologies to treat the problem, like the water transfer projects being done right now, but they are draining resources in a very wrong way."
According to Reuters, China's water resources per person stands at 2,100 cubic meters, just 28 percent of the global average. Beijing says it will spend trillions of yuan to clean the country's rivers, increase water supply, and protect water tables. Meanwhile, in Minqin, the damage has already been done.

Debates over historic preservation often run into a problem: There’s plenty of data to support economic arguments, and much less to address questions of cultural value. A research team in Singapore wants to change that.
