HANOI -- The 3.6 hectares in southern Vietnam that double as rice paddy and shrimp pond for farmer Nguyen Thi Tam have become a wasteland. After the worst drought in 90 years, almost nothing grows.
Mrs Tam's family had no income for two harvests because the rice crop failed and the shrimp died. They ran up US$8,000 in debt -- more than twice her earnings in a typical year. To make ends meet, Mrs Tam plans to leave her village to work at a factory hundreds of kilometres away. Many others in the area already have fled, she said, including her daughter-in-law, who couldn't endure the poverty.
"I am worried about everything," Mrs Tam, 55, said inside the thatched house in Kien Giang province she shares with her husband, three grown children and two grandchildren. "I cannot sleep."
The dry spell in the once-fertile Mekong Delta is devastating food supplies in southern Vietnam and threatening to reduce global exports of rice, seafood and coffee. It is also compounding a Southeast Asia water shortage along a 4,800-kilometre river that runs from Tibet to Thailand to the South China Sea, as climate change and too many dams erode livelihoods for millions of farmers.
More shortages
Waters in the Mekong Delta, a network of channels that cut across vast flatlands in southern Vietnam, are at the lowest in almost a century, which may mean shortages for as much as 50% of the region this year, according to a United Nations report. That means less for irrigating crops and an increase in salt levels as more seawater seeps into the delta, causing more damage.

The Mekong River countries of Vietnam, Thailand, Laos, Cambodia and Myanmar produce about 62 million tonnes of rice, or 13% of global output, US Department of Agriculture data show. The river accounts for as much as 25% of the global freshwater catch and provides livelihoods for at least 60 million people, according to the World Wildlife Fund. Vietnam exported about $3 billion of shrimp last year. Almost half of Vietnam's population of 91 million works in agriculture, which accounts for about 13% of the economy.
"People in Indonesia and the Philippines will go hungry if the Thais and Vietnamese don't produce enough rice," said Richard Cronin, director of the Southeast Asia Program at the Stimson Center in Washington. "This is a preview of the longer-term effect of development and climate change to the Mekong Delta."
More dams
Rice exports from Vietnam, the world's third-largest shipper, probably will drop 10% this year because of lower production, said Do Ha Nam, the chief executive officer of Intimex Group, a major Vietnam exporter of agricultural products. Rice output from the Mekong Delta fell 6.2% in the first quarter from a year earlier, reducing the country's total agricultural production by 2.7%, according to Nguyen Bich Lam, head of the General Statistics Office.

Water from the Mekong was already under pressure before the drought, which the UN attributed to a stronger-than-normal El Nino weather pattern. China has completed six of seven major dams on the river in southern Yunnan province, Mr Cronin said. Vietnam has built dozens in the Central Highlands, which, like the Chinese and Laotian dams, deprive the Delta region of the critical sediments needed to replenish eroded soil, he said.
Eleven more dams planned in Thailand, Laos and Cambodia could result in fish and farming losses of $750 million in Vietnam and $450 million in Cambodia, with extinctions for as much as 10% of fish species in the region, according a study submitted to the Mekong River Commission, a group created to mediate water disputes.
Vietnam's government, which relied on rice farming to feed its population during years of dire poverty after its war with the US, needs to encourage Mekong Delta farmers to switch to more profitable crops, such as fruit trees that require less water, and raise higher-value shrimp in coastal areas, said Vo-Tong Xuan, a professor of agronomy and rector of Nam Can Tho University.
Costly change
It's not that easy to switch, said Nguyen Trung Kien, vice chairman of the Vietnam Food Association. Fruit trees can take years before the first harvest, he said.
The drought is changing the landscape in the Mekong Delta. Along National Road 63 in coastal Kien Giang province, the soil is parched and cracked on land once soaked with water for rice paddies tended by Vietnamese in conical hats. Sugar-cane trees that should be green have yellowed.

"This is the first time in my 22 years of rice farming I could not grow rice," said Nguyen Van Nhin, 36, who tends nine acres in Kien Giang province behind his thatched-roof hut with wood-plank beds and mosquito nets.
In Kinh 5, Nhin's village, 70% of the 281 farms produced no rice this season, said Danh Nhac, the local vice chief of the Communist Party. "The majority of the people left in the hamlet are children and people older than 45 or 50."
For those who remain, it means looking for alternatives to commercial farming. Mr Nhin is trying to grow vegetables for food and looking for work as a manual labourer.
"I am just waiting for the rain to return so I can grow rice again," he said.
