Water wars? Thirsty, energy-short China stirs fear

BAHIR JONAI, India (AP) — The wall of water raced through narrow Himalayan gorges in northeast India, gathering speed as it raked the banks of towering trees and boulders. When the torrent struck their island in the Brahmaputra river, the villagers remember, it took only moments to obliterate their houses, possessions and livestock.

No one knows exactly how the disaster happened, but everyone knows whom to blame: neighboring China.

"We don't trust the Chinese," says fisherman Akshay Sarkar at the resettlement site where he has lived since the 2000 flood. "They gave us no warning. They may do it again."

About 800 kilometers (500 miles) east, in northern Thailand, Chamlong Saengphet stands in the Mekong river, in water that comes only up to her shins. She is collecting edible river weeds from dwindling beds. A neighbor has hung up his fishing nets, his catches now too meager.

Using words bordering on curses, they point upstream, toward China.

The blame game, voiced in vulnerable river towns and Asian capitals from Pakistan to Vietnam, is rooted in fear that China's accelerating program of damming every major river flowing from the Tibetan plateau will trigger natural disasters, degrade fragile ecologies, divert vital water supplies.

A few analysts and environmental advocates even speak of water as a future trigger for war or diplomatic strong-arming, though others strongly doubt it will come to that. Still, the remapping of the water flow in the world's most heavily populated and thirstiest region is happening on a gigantic scale, with potentially strategic implications.

On the eight great Tibetan rivers alone, almost 20 dams have been built or are under construction while some 40 more are planned or proposed.

China is hardly alone in disrupting the region's water flows. Others are doing it with potentially even worse consequences. But China's vast thirst for power and water, its control over the sources of the rivers and its ever-growing political clout make it a singular target of criticism and suspicion.

"Whether China intends to use water as a political weapon or not, it is acquiring the capability to turn off the tap if it wants to — a leverage it can use to keep any riparian neighbors on good behavior," says Brahma Chellaney, an analyst at New Delhi's Center for Policy Research and author of the forthcoming "Water: Asia's New Battlefield."

Analyst Neil Padukone calls it "the biggest potential point of contention between the two Asian giants," China and India. But the stakes may be even higher since those eight Tibetan rivers serve a vast west-east arc of 1.8 billion people stretching from Pakistan to Vietnam's Mekong river delta.

Suspicions are heightened by Beijing's lack of transparency and refusal to share most hydrological and other data. Only China, along with Turkey, has refused to sign a key 1997 U.N. convention on transnational rivers.

Beijing gave no notice when it began building three dams on the Mekong — the first completed in 1993 — or the $1.2 billion Zangmu dam, the first on the mainstream of the 2,880-kilometer (1,790-mile) Brahmaputra which was started last November and hailed in official media as "a landmark priority project."

The 2000 flood that hit Sarkar's village, is widely believed to have been caused by the burst of an earthen dam wall on a Brahmaputra tributary. But China has kept silent.

"Until today, the Indian government has no clue about what happened," says Ravindranath, who heads the Rural Volunteer Center. He uses only one name.

Tibet's spiritual leader, the Dalai Lama, has also warned of looming dangers stemming from the Tibetan plateau.

"It's something very, very essential. So, since millions of Indians use water coming from the Himalayan glaciers... I think you (India) should express more serious concern. This is nothing to do with politics, just everybody's interests, including Chinese people," he said in New Delhi last month.
