Growing Shortages of Water
Threaten China’s Development

With 20 percent of the world’s population but just 7 percent of its available freshwater, China faces serious water shortages as its economy booms and urbanization increases. The government is planning massive water diversion projects, but environmentalists say conservation — especially in the wasteful agricultural sector — is the key.

by christina larson

On a recent visit to the Gobi desert, which stretches across China’s western Gansu province, I came upon an unusual sign. In the midst of a dry, sandy expanse stood a large billboard depicting a settlement the government intended to build nearby — white buildings surrounded by lush, green, landscaped lawns, and in the center a vast, gleaming blue reservoir. The illustration’s bright colors were quite unlike the actual surroundings, which consisted of dull sky that faded into a horizon of undulating, parched-brown hillsides.

Still, the billboard’s promise was clear: Through feats of engineering and willpower, specifically the planned construction of a series of aqueducts to bring water from a tributary of China’s Yellow River, the government pledged to build new homes and remake nature. Let there be water.

My companion, the young Chinese environmentalist Zhao Zhong, founder of the nonprofit group, Green Camel Bell, was dubious. He pointed out that not only has the water level of the Yellow River been declining in recent years, in some months no longer reaching the Pacific Ocean, but that the river is now an estimated 10 percent sewage by volume. Watering the desert seemed to him, quite literally, a pipe dream.

Yet the sign conjuring an oasis in the desert does point to a very real dilemma: In order to sustain its rapid development, China needs a lot of water. It can only build as many cities as it can supply with clean water. And the country’s water supply is precariously limited: The Middle Kingdom is home to 20 percent of world’s population, but just 7 percent of its available freshwater resources. Rapid urbanization is quickly increasing demand for fresh water, while climate change threatens to further reduce availability.

Wang Rusong, an expert in urban ecosystems at the Chinese Academy of Sciences and an environmental advisor to Beijing’s mayor, told me when I visited his offices in May that China’s most worrisome environmental challenge is not what it has too much of — pollution, sewage, carbon emissions, etc. — but what it doesn’t have enough of: “The limiting factor in Beijing’s development is water,” he said. And Beijing is hardly alone.

Over the next 20 years, 350 million people in China — more than the population of the United States — are expected to move from the countryside to the cities, requiring an immense infrastructure build-out. (Imagine constructing all America’s cities in one generation.) One measure
World Bank estimates show China has only one-fourth the global average amount of water per capita.
of the nation’s rapid growth and urbanization is its production of cement — China is by far the world’s largest user of cement, producing seven times more cement than the second-largest user, India. For other natural resources, Beijing is scouring the earth: importing vast quantities of timber from Southeast Asia and Latin America; financing oil rigs in Nigeria, Chad, and Sudan; investing in copper mines in Afghanistan. Yet securing enough fresh water may be the gravest challenge of all, as it is the one resource that cannot be imported.

Instead, China must learn to make do with the water it has. World Bank estimates show that China possesses only one-fourth the global average amount of water per capita. As more and more of its people move to cities, household demands will grow. Professor Wang estimates that Beijing’s water use has grown 150 percent in just the last decade. China’s power sector is extremely water-intensive, and steeply rising energy use is also driving water demand.

A recent study, “Charting Our Water Future,” by the global consultancy, McKinsey and Co., and the Water Resources Group, looks at increasing water demand across sectors (residential, agricultural, industrial) and forecasts that by 2030 China could face a gaping water shortage of 201 billion cubic meters. To make matters worse, much of the available water is located in southern China, while the majority of the population is in the north.

Across China today, one encounters frequent scenes of people struggling to deal with water scarcity. In Gansu province, not far from where the billboard boasts of a modern oasis, local farmers eke out an existence growing vegetables in low greenhouses that they cover with straw mats to retain every last drop of moisture. “There is nothing to spare,” one 40-something farmer told me. Nearby, the wells supplying rural schools have had to be dug deeper in recent years, as groundwater levels sink. In many Gansu villages, canals that run behind homes are dry in the winter months.

In southwest China, a severe drought this spring affected as many as 18 million people, drying fields and limiting drinking water to residents in large cities. Such water-scarce regions in China have little buffer against even naturally occurring dips in precipitation — a problem that could be exacerbated as the world warms. As Ma Jun, author of the seminal book, China’s Water Crisis, explained: “In some regions, the environmental capacity is very low, and the groundwater is now quite depleted. We have either to change our livelihoods, or make space for natural restoration to happen. We have to recognize that in certain parts of our earth, existence is fragile.”

In northern China and adjacent Mongolia, the sands of the Gobi desert are expanding — a process known as “desertification” — largely due to land-use changes, soil erosion, and perhaps climate shifts. Each spring, seasonal sandstorms strike Beijing; on the worst days, the skies are yellow, and residents are advised to remain inside. In the 1950s, sandstorms hit Beijing only every seven or so years; now they strike each spring.

In western China, the melting glaciers on the Tibetan-Qinghai Plateau have already begun to shrivel streams in Tibet, Qinghai, and Gansu. The Chinese Academy of Social Sciences estimates that the glaciers, the world’s largest outside the poles, are shrinking by about 7 percent each year. Tenzin Dorje, a Tibetan shepherd living in the rugged Qilian mountains, where streams are fed by glaciers, says that each year he must trudge further to find streams where his sheep can drink.

In west China, the Chinese government projects that 150 million people must move from their homes to secure reliable access to water. As Wen Bo,
‘We can’t think only about economic development, we have to think about ecological capacity,’ says Wen Bo.
an environmentalist in Beijing, points out: “This is a clear indication that we can’t think only about economic development. We have to think about ecological capacity.” He adds that part of the problem is man-made. “Problematic irrigation policies and dam construction [on the nearby Yangtze River] contributed to the recent drought,” he says. “China is not good at water resources management.”

Indeed, Beijing’s typical mindset is to dig its way out of a hole and fight challenges with massive engineering projects. One example is the plan to move vast quantities of water from the southern Yangtze River to the northern Yellow River through a series of grand aqueducts carved through mountainsides and etched across deserts; the eastern leg of the project has already been built, but subsequent stretches appear, many argue, to be geologically and financially unsound. Yang Yong, an independent Chinese geologist who has studied some of the engineering pitfalls of the current proposals, estimates that there may be better ways to approach the dilemma: “You can get more water through better conservation measures than actually building the South-to-North Water project,” he said.

Indeed, China is starting to emphasize conservation. The city government of Beijing last December announced price hikes of 8 percent on residential water use, one of a series of such increases across the country recently designed to discourage household water waste. As Julian Wong, a senior fellow at the Center for American Progress in Washington, DC, observes: “Natural resource inputs have long been underpriced in China. Conservation measures are going to be a priority in the coming years.”

A Struggle Over Sound Science

Currently the greatest culprit of water waste in China is the agricultural sector, which accounts for more than two-thirds of all water use. Yet up to 45 percent of that water disappears before it reaches farmers — evaporating off the surface of open canals, seeping into the dirt walls of poorly constructed rural diversions, or being literally skimmed off the top by any number of unaccounted-for water users, according to research by Christine Boyle, a recent Fulbright fellow at the Chinese Academy of Science’s Center for Chinese Agricultural Policy. She points out that when it comes to water management in China, “there are a lot of moving parts, but not a lot of oversight.”

The reasons for such water waste include poor rural infrastructure (every village or district is responsible for maintaining its irrigation infrastructure, and some have little money for repairs); lack of coordination between governing bodies; and lack of measurements or accountability to tell where, precisely, water is being lost.

Recognizing the problem is the first step to fixing it. As Professor Wang told me in Beijing, “First we have to change people’s minds – then our systems.”

Has the author considered the possibility that northern China would import water from sparsely populated eastern Siberia? It seems technically feasible and I would not be surprised if there are already people hoping to make a huge profit that way.

Even Italy and Spain cannot manage their water and agriculture is also the main culprit there, using the water if it's available and in an ineffective way.

Can China do better than these Mediterranean countries? Perhaps, and most probably, the solution will be a combination of (martial) engineering efforts and enforcement by government bodies.

Water conservation and in situ water resources development are advantageous to the alternative approach of large-scale inter basin water transfer. Disputes and conflicts are a few, environmental clearance may not be required, land acquisition is minimal, short gestation period, relatively lower investments, etc. are associated with the water conservation. In fact, large-scale water transfer should be given second priority once all other options are tried and exhausted. Can China follow these examples, similar to India, before venturing the mega water transfer projects?

how about desalination plants? they're common in the U.S.. Australia and Israel also use them.

Why not install many desalination plants. After all, they do border the largest ocean in the world, the Pacific Ocean.

As someone who studied Chinese political systems in my long since passed undergraduate years (Indiana University & University of Oregon), I've gotten "back into this area because I've been reading an intelligence digest, STRATFOR, daily. STRATFOR has pointed out that Hu Jinato's term of office is coming closer to ending, and the "Fifth Generation" of CCP leaders queuing up includes more technocrats than the previous generations "revolutionaries."

In fact, several books I've read confirm that the technocrats have swamped the Politburo and Politburo Standing Committee, as well as several key committees or groups of the CCP, compared to "revolutionary types."

In studying a book by Andrew Nathan & Bruce Gilley, entitled: "China's New Rulers: The Secret Files," and also "The Tiananmen Papers," I noticed that NONE appear to have any specific career backgrounds in water management. While many of the possible leaders of the Fifth Generation have served in various county, prefecture & province capacities, I wonder how many have been heavily involved in the juggling act described as concerns itself with water.

The most troubling aspect of your report, Ms. Larson, is that the glaciers in Tibet are receding by 7% a year!!! The Tibetan headwaters area, of course, provide water not only to China, but India, Myanmar, and Pakistan, to name a few. I believe I heard reports that the Chinese had given some thought to daming the headwaters of the Brahmaputra.

If so, is that the first salvo China has fired re: the sequestration of headwaters for their own political survival. The key issue that the CCP is fixated on, from what I can see, is to maintain the stability of the regime so far as social unrest is concerned.

A recent viewing of a Chinese film that covered the Tianamen Uprising was stunning when one saw the enormous crowds of people, milling and swarming into Beijing during the Tiananmen Movement. It was clear then that the CCP must absolutely be freaked when they conceive of massive, nation wide, political unrest.

Water shortages could have severe impact on the Chinese growth phenomenon in the near term, as there are reports that food shortages in certain areas may cause inflationary pressures in the next year.

You might know best whether there are, in fact, some acute areas of food shortages already occuring in China this year. Or, if they're expected to stretch into 2011. This could unravel the work of Hu Jintao, for sure. As these Chinese Party leaders seem hypersensitive to their "legacies, the unraveling of Hu Jintao's "era" at the tail end could cause all kinds of warped thinking. Or, perhaps, not?

I'm not sure what your thoughts are on these conjectures of mine, but it's clear as I watch CNBC daily, and pay attention to STRATFOR, that the average American is absolutely convinced in the invincibility of an emerging China as a Superpower.

On the other hand, if the water shortages are as severe as you outline, can this be realistic? Are we not talking about some real razzle dazzle? As you suggest, with the Chinese promise of an "oasis" somewhere in the future of Gansu Province, a joke, how far do you believe the total picture for China is, if they have a fairly resistant wall on water resources.

Hit the wall? When? How severe a crash? What natural disasters have affected Chinese agriculture, by the way, if you know?

I think another reason for shortages are leaking water pipes. A large percentage of Chinese water disappears unused in the ground. Water wastage is very serious, especially in South East Provinces.

I agree with Paul Collins :D is a very good reason for shortages are leaking water pipes.

China's house of cards...lack of water, losing farms, land and housing bubble, stock market bubble, looming pension plan disaster, rampant corruption, uncontrollable local governments, ever growing income disparities, land grabs, looming demographics disaster, pollution, pollution, pollution... and some call them a super power.
