India Wants to Find the Saraswati River and Bring It Back to Life – India Real Time – WSJ

ndia’s new government says it plans to find and possibly bring back to life a long-lost river mentioned in sacred Hindu texts.

In answer to a question in Parliament Tuesday, Uma Bharti, the water resources and river development minister said India wants to “detect and revive,” the Saraswati River, described in Vedic texts.

“There are enough scientific evidences on the presence of the river Saraswati in some parts of the country through which it flowed about five to six thousand years ago,” she said on the floor of the lower house of Parliament. “Saraswati is not a myth.”

Geologists have known for more than 100 years about ancient river beds passing through northern India that could be the Saraswati, said the Times of India. But reviving the river by bringing any underground water to the surface is “an impossible task,” Umesh Chaube, professor emeritus of water resource development and hydrology at IIT –Roorkee told the Hindustan Times.

Critics were quick to suggest it would be a waste of government money and a potential wild goose chase aimed at strengthening the ruling Bharatiya Janata Party’s ties to its Hindu nationalist supporters.

A BJP spokesman did not respond to a request for the party response on Wednesday morning.

It wouldn’t be the first time that scientists have had to follow the hunches of politicians. Last year a team of government archaeologists had to excavate the ruins of an old palace in the state of Uttar Pradesh, after a famed Hindu holy man declared that there was 1,000 tons of gold buried under it. No gold was found.

Scientists Say Water Shortages Threaten China’s Agriculture – Businessweek

China has a fifth of the globe’s population but only 7 percent of its available freshwater reserves. Moreover, its water resources are not evenly distributed. The lands north of the Yangtze River—including swaths of the Gobi desert and the grasslands of Inner Mongolia—are the driest, but more than half of China’s people live in the north.

Water is not well managed in China. Nearly two-thirds of water withdrawals in China are for agriculture. Due to the use of uncovered irrigation channels (leading to evaporation) and other outdated techniques, a significant portion of that water never reaches the field.

A new paper by scientists in China, Japan, and the U.S. published in the Proceedings of the National Academy of Sciences sounds the alarm: “China faces … major challenges to sustainable agriculture,” the authors write. Failure to conserve water resources could threaten China’s food security, a longtime priority for the country’s leaders.

* China to spend $330 billion to fight water pollution -paper | Reuters

China has a fifth of the world’s population but just 7 percent of its water resources, and the situation is especially precarious in its parched north, where some regions have less water per capita than the Middle East.

The plan is still being finalized but the budget has been set, exceeding the 1.7 trillion yuan ($277 billion) China plans to spend battling its more-publicized air pollution crisis, the China Securities Journal reported, citing the Ministry of Environmental Protection.

It will aim to improve the quality of China’s water by 30 to 50 percent, the paper said, through investments in technologies such as waste water treatment, recycling and membrane technology.

The paper did not say how the funds would be raised, when the plan would take effect, or what timeframe was visualized, however.

Groundwater resources are heavily polluted, threatening access to drinking water, Environment Minister Zhai Qing told a news conference in the capital, Beijing, last week.

According to government data, a 2012 survey of 5,000 groundwater check points found 57.3 percent of samples to be heavily polluted.

China emits around 24 million tons of COD, or chemical oxygen demand, a measure of organic matter in waste water, and 2.45 million tons of ammonia nitrogen, into its water each year, Zhai said.

Over the next five years, China has previously estimated it will need to spend a total of 60 billion yuan to set up sludge treatment facilities, and a further 10 billion yuan for annual operation, the environment ministry says.

China is short on water to begin with but its water problems are made worse by its reliance on coal – which uses massive amounts of water to suppress dust and clean the fuel before it is burnt – to generate nearly 70 percent of its electricity while self-sufficiency in food remains a key political priority.

China’s Coal Thirst Strains Its Water Supplies

BusinessWeek: “The Wulanmulun River once ran through Daliuta, a town in China’s northern Shaanxi province. All that remains of the waterway today is a pond, which locals say is contaminated by waste from the world’s biggest underground coal mine. Environmentalists also contend that mining is sapping the area’s groundwater supplies. “I worry about the water,” says Zhe Mancang, the 58-year-old owner of a liquor store in town. “But my family’s here, and my customers are from the mines.”

Daliuta is the epicenter of a looming collision between China’s scarce supplies of water and heavy reliance on coal, which diverts millions of liters a day for its extraction and cleaning. “You can’t reconcile targets for coal production in, say, Shaanxi province and Inner Mongolia with their water targets,” says Charles Yonts, head of sustainable research at brokerage CLSA Asia-Pacific Markets in Hong Kong.

About 28,000 rivers have dried up across China since 1990, according to the country’s Ministry of Water Resources and National Bureau of Statistics of China, and those that remain are mostly polluted. China’s per-person share of fresh water is 1,730 cubic meters, close to the 1,700 cubic meter level the United Nations deems “stressed.”

The situation is worse in the north, where half of China’s population, most of its coal, and only 20 percent of its water are located. A government plan to boost coal production and build more power plants near mines will lift industrial demand for water in Inner Mongolia 141 percent by 2015 from 2010 levels, causing aquifers to dry up and deserts to expand, according to a report Greenpeace commissioned from the Chinese Academy of Sciences. “After five years there won’t be enough water in Ordos in Inner Mongolia,” says Sun Qingwei, director of the climate and energy campaign at Greenpeace in Beijing. “The mines are stealing groundwater from agriculture. Local governments want their economies to boom.”

China’s central government is responding with tighter limits on water usage, a new approach to rates that allows for steep price increases, and plans to spend 4 trillion yuan ($652 billion) by 2020 to boost water infrastructure. Rules enacted this year require the manufacturing hubs of Jiangsu and Guangdong provinces and Shanghai to reduce water use every year even as their economies expand. In May 2012 authorities in the city of Guangzhou hiked prices 50 percent for residents and 89 percent for industrial users to help pay for improvements in the water supply, according to an April report by Goldman Sachs Group (GS).

To alleviate shortages in the north, the central government in 2002 approved the 500 billion yuan South-to-North water diversion project. The plan is to move 44.8 billion cubic meters of water from the Yangtze River annually along three routes. The first leg, slated for completion this year, will measure 1,467 kilometers, roughly double the length of the Erie Canal.

Even this massive undertaking may not be enough: A 2009 report by a group that includes Coca-Cola (KO) and SABMiller (SBMRY) noted that China’s annual demand may exceed supply by as much as 200 billion cubic meters by 2030, unless “major capital investments to strengthen water supplies are made beyond those presently planned.”

Chinese industry uses 4 to 10 times more water per unit of production than the average in developed countries, according to research firm China Water Risk in Hong Kong. Only 40 percent of industrial water is recycled, compared with 75 percent to 85 percent in developed countries, the World Bank says.

If the situation becomes dire enough, companies might consider transferring production elsewhere. “In an absolute worst case you’d see a large-scale shift in economic activity and population further south for lack of water, and manufacturing increasingly moving abroad,” says Scott Moore, a research fellow at the Harvard Kennedy School’s Sustainability Science Program.

Farmers in some parts of China are already paying the price, as they have to dig deeper and deeper wells to find clean water or are being forced out by local governments who see bigger economic gains from mining. In Zhanggaijie village, in Shaanxi province, Li Qiaoling says she is one of 200 people awaiting compensation after a coal mine polluted the local water supply. Officials have also promised to relocate the villagers. “We’re angry because we have to leave,” says Li, who still grows corn on her small plot, despite the contamination. “We’re worried about moving to a strange place.”

* Tibet to invest $563m to protect environment

China Daily: The government of the Tibet autonomous region plans to invest more than 3.5 billion yuan ($563 million) in 2013, 10.5 percent more than last year, in environmental protection.

According to the draft budget of 2013, which the regional finance department submitted for the legislature’s approval on Thursday, the investment will also support the building of an ecological safety screen on the plateau.

More than 3.23 billion yuan will be used for major forestation projects and for compensating and rewarding locals who protect and grow grass and forests and conserve wetlands, lakes and water resources.

More than 50 million yuan will be allocated to support environmental improvement projects and preserve resources, according to the draft budget.

According to the autonomous region’s environmental protection department, the plateau’s fragile and sensitive environment faces a worsening situation of land desertification, soil erosion and threats to deteriorating biodiversity.

New challenges are emerging from increasing urban pollution related to tourism, traffic and mining.

However, environmental protection has also received “unprecedented” attention over the past five years, the department said.

The State Council, China’s cabinet, listed the protection and building of a safety screen of environment in Tibet as a State-level major eco-project in February 2009.

The project aims to pour in 15.5 billion yuan to basically finish building the screen by 2030.”
