100-Year Drought In Vietnam - In Some Areas, Sea Water Has Moved 40 Miles Inland

Every year, even at the peak of Vietnam's dry season, when the Red River is at its lowest, Hanoi's skilled captains manage to negotiate their flat-bottomed boats through its shallow waters. But this year, with a drought gripping the entire country and water levels at record lows, the river is eerily quiet. What is normally a bustling waterway is becoming a winding river of sand, and farmers who depend upon the river for irrigation are watching the expanding sandbars as nervously as the boat captains. "If there is no water in the coming days," says 59-year-old farmer Vu Thi La, who just put in her spring rice seedlings, "it will all die."

Across Vietnam, high temperatures and parched rivers are setting off alarm bells as the nation grapples with what's shaping up to be its worst drought in more than 100 years. At 0.68 meters high, the Red River is at its lowest level since records started being kept in 1902. With virtually no rainfall since September, timber fires are burning in the north and tinder-dry conditions threaten forests in the south. Soaring temperatures in the central part of Vietnam have unleashed a plague of rice-eating insects, damaging thousands of hectares of paddies. "It's the beginning of everything," Nguyen Lan Chau, vice director of the National Center for Hydro-Meteorological Forecasting, says gloomily. (See pictures of the world's water crisis.)

The region most affected — and the one that affects the most — is the Mekong River Delta in the south. Water levels in the nation's rice bowl have fallen to their lowest points in nearly 20 years, threatening the livelihoods of tens of millions of people who depend on the river basin for farming, fishing and transportation. The biggest problem, however, is not the water. It's the salt. During the dry season, when channels and tributaries run dry, seawater can creep more than 18 miles (30 km) inland. Vietnam has installed a series of sluice gates to hold back high tides as well as control annual monsoon flooding. This has allowed farmers to switch between growing rice in the wet season and raising shrimp in the brackish waters in the dry. The result has been more-effective land use and higher crop yields, and a doubling of farmers' incomes in the Delta since 1999.

Those high-yield days may be over. As the drought intensifies, in some places seawater has crept nearly 40 miles (60 km) inland, says Dam Hoa Binh, deputy director of the Irrigation Department at the Ministry of Agriculture and Rural Development in Hanoi. Most of the winter-spring crop has already been harvested, but saltwater is reaching where it has never gone before, putting the summer-fall crop in jeopardy, says Binh. "We are trying to strengthen our irrigation systems to prevent further salinization," he adds, but the extreme conditions are making it "one of the most difficult situations in 100 years."

1. We may just have to bomb

the hell out of it to save it. Then the fresh water could collect in the bomb craters to irrigate with.
