Vietnam’s prolonged drought, coupled with an extensive build-up of salinity, have driven five provinces in the country’s rice bowl to declare a state of emergency. “This year’s drought and salinity have been way more devastating than what we saw four years ago,” said Nguyen Thien Phap, head of the water resources department in Tien Giang, one of the provinces that announced the emergency in the Mekong Delta.

“The entire area of fruit trees in Tien Giang province, or about 80,000 hectares (310 square miles), are at risk, while 24,000 hectares of rice fields will give below-normal yields”, said Mr. Phap, who added that water usage upstream on the Mekong by nations including China, Laos and Thailand increased the dryness. The Mekong Delta, which produces more than half the country’s rice, has so far seen a total of 33,000 hectares of rice fields damaged and nearly 70,000 households suffer from lack of water, Vietnam National Television reported Friday, citing latest data from the country’s department of water resources.

The government estimates drought will affect 362,000 hectares of rice and 136,000 hectares of fruit trees in the Delta this year, while more than 120,000 households will experience a water shortage. As of March 2020, it had hit about half the districts in 10 of the 12 provinces and one city in the region. The persistent drought in the Delta in 2016 caused losses worth 8.9 trillion dong (384 million USD) with 250,000 hectares of rice, 130,000 hectares of crops and 30,000 hectares of fruit trees destroyed, according to local news website VnExpress. It was regarded as the worst drought in the region of more than 17 million people in data going back to 1926.

While the Delta is a key rice-growing area, the crop is grown in almost all of Vietnam, which is the world’s third-largest exporter, behind India and Thailand. What will happen if this situation gets worse?
