China's struggle for water security

Daegu (South Korea) (AFP) - Way back in 1999, before he became China's prime minister, Wen Jiabao warned that water scarcity posed one of the greatest threats to the "survival of the nation".

Sixteen years later, that threat looms ever larger, casting a forbidding shadow over China's energy and food security and demanding urgent solutions with significant regional, and even global, consequences.

The mounting pressure on China's scarce, unequally distributed and often highly polluted water supply was highlighted in a report released at the World Water Forum this week in Daegu, South Korea.

Published by the Hong Kong-based NGO, China Water Risk (CWR), it underlined the complexity of the challenge facing China as it seeks to juggle inextricably linked and often competing concerns over water, energy supply and climate change.

"There are no one-size-fits-all solutions to China's water-energy-climate nexus," the report said.

"More importantly, China's energy choices do not only impact global climate change, but affect water availability for Asia," it said, warning of the danger of future "water wars" given China's upstream control over Asia's mightiest rivers.

The Qinghai-Tibetan plateau is essentially the world's largest water tank and the origin of some of Asia's most extensive river systems including the Indus, Brahmaputra and Mekong.

The most significant link in the nexus the report describes is the fact that 93 percent of China's power generation is water-reliant.

"Chinese officials are starting to say water security comes first," the report's author Debra Tan told AFP in Daegu. "Because without it, there is no energy security and, of course, no food security."

Kung Pao potato

Agriculture accounts for between 65 and 70 percent of China's water use and vast amounts are wasted by inefficient irrigation.

This is especially true in northern regions that, despite being some of the most arid in the country, are the production focus for water-hungry crops like corn and wheat.

"They even grow corn in Inner Mongolia, which is incredibly dry," said Li Lifeng, director of the WWF International Freshwater Programme.

"I recently talked to a farmer there who had been growing corn for just three years," Li said in Daegu. "His well started off three metres (10 feet) deep, but now it already goes down 50 metres."

Efforts to change the crop mix have included a recent campaign to promote the harvesting of potatoes, which require far less water.

Given the traditional taste preference for rice and wheat, the state broadcaster CCTV has tried to prod things along by publishing recipes on its Weibo account, including one for Kung Pao potato.

Northern China's thirst for water -- the coal industry is centred there as well -- extends to its rapidly growing and increasingly affluent urban populations.

The need to meet the rising demand from these cities resulted in one of the world's most ambitious engineering projects, with an overall estimated cost of more than $80 billion.

The central phase of the massive South-North Diversion Project opened in December, as water began flowing to Beijing through more than 1,200 kilometres (745 miles) of channels and pipes -- the distance from London to Madrid.

But experts stress that China cannot simply engineer its way out of its water crisis with headline mega-projects that will never be big enough to keep pace with increasing demand.

'Good water after bad'

A study published in the Proceedings of the National Academy of Sciences journal in January warned that large-scale water transfers would actually exacerbate problems in the long-run.

"China needs to shift its focus to water demand management instead of a supply-oriented approach," said the study's co-author, Dabo Guan, a professor at the University of East Anglia.

"The current transfer programme is pouring good water after bad: the problems of water-stressed regions aren't being alleviated and the provinces sharing their water are suffering greatly," Guan said.

Years of declining rainfall in southern China means it now regularly sees droughts of its own.

China is in fact implementing an extremely ambitious water management strategy, albeit one that risks being undermined by inter-departmental rivalries, corruption and incentives that favour economic development over sustainable resource use.

In 2011, it issued its "three red lines" policy establishing strict limits on water quantity usage, efficiency and quality, while this year a new Environment Law came into force with harsh fines for polluters.

State media reported last year that 60 percent of China's groundwater and more than half its major freshwater lakes were polluted.

"Before, there wasn't much of a stick for punishing wastage and polluting," said CWR's Tan. "Now there are strict standards and a very big stick."

Having experimented with charging urban residents for water in order to encourage conservation, the government is reportedly set to roll out a tiered pricing system for residential users in all cities and some towns nationwide later this year.

“…  4 - Energy (again)

The natural resources of the planet are finite and will not support the continuation of what you've been doing. We've been saying this for a decade. Watch for increased science and increased funding for alternate ways of creating electricity (finally). Watch for the very companies who have the most to lose being the ones who fund it. It is the beginning of a full realization that a change of thinking is at hand. You can take things from Gaia that are energy, instead of physical resources. We speak yet again about geothermal, about tidal, about wind. Again, we plead with you not to over-engineer this. For one of the things that Human Beings do in a technological age is to over-engineer simple things. Look at nuclear - the most over-engineered and expensive steam engine in existence!

Your current ideas of capturing energy from tidal and wave motion don't have to be technical marvels. Think paddle wheel on a pier with waves, which will create energy in both directions [waves coming and going] tied to a generator that can power dozens of neighborhoods, not full cities. Think simple and decentralize the idea of utilities. The same goes for wind and geothermal. Think of utilities for groups of homes in a cluster. You won't have a grid failure if there is no grid. This is the way of the future, and you'll be more inclined to have it sooner than later if you do this, and it won't cost as much.

Water

We've told you that one of the greatest natural resources of the planet, which is going to shift and change and be mysterious to you, is fresh water. It's going to be the next gold, dear ones. So, we have also given you some hints and examples and again we plead: Even before the potentials of running out of it, learn how to desalinate water in real time without heat. It's there, it's doable, and some already have it in the lab. This will create inexpensive fresh water for the planet. 

There is a change of attitude that is starting to occur. Slowly you're starting to see it and the only thing getting in the way of it are those companies with the big money who currently have the old system. That's starting to change as well. For the big money always wants to invest in what it knows is coming next, but it wants to create what is coming next within the framework of what it has "on the shelf." What is on the shelf is oil, coal, dams, and non-renewable resource usage. It hasn't changed much in the last 100 years, has it? Now you will see a change of free choice. You're going to see decisions made in the boardrooms that would have curled the toes of those two generations ago. Now "the worst thing they could do" might become "the best thing they could do." That, dear ones, is a change of free choice concept. When the thinkers of tomorrow see options that were never options before, that is a shift. That was number four. ….”
