Saltwater intrusion threatens rice farming in delta

(10:46:55 AM 17/03/2014)
(Tinmoitruong.vn) - Saltwater intrusion is getting more severe in many areas in the Mekong Delta region and thousands of hectares of rice and plants are forecast to be affected in the coming time.

 

According to Ben Tre Province’s Irrigation Department, saltwater is intruding in the Ham Luong, Cua Dai and Co Chien rivers 34-38 kilometers upstream.

 

In the Daily’s observations, since the year’s beginning, all dam and sewer systems along the Tien and Hau rivers in Tra Vinh Province are storing water and restricting water discharge to ensure sufficient freshwater for local residents and farmers in the coming time.

 

Meanwhile, Hau Giang Province is building temporary dams to protect rice of the winter-spring crop and prepare for rice farming of the summer-autumn crop, said Nguyen Van Dong, director of the provincial Department of Agriculture and Rural Development.

 

According to Dong, saltwater will leave a huge impact on farming in Hau Giang, especially the summer-autumn crop.

 

There will be 7,000-8,000 hectares of rice in Vi Thanh City, Vi Thuy and Long My districts to be affected, Dong said.

 

However, the Irrigation Department in Hau Giang Province said that saltwater has approached Vi Thanh City.

 

Meanwhile, according to Hau Giang Hydro-meteorological Center, salinity will continue to rise high from late this month and further intrude the city.

 

Coastal provinces in the region like Tien Giang, Soc Trang, Kien Giang, Bac Lieu and Ca Mau are also witnessing saltwater encroaching on land and threatening thousands of hectares of rice and many other plants.

 

In related news, though the dry season has just begun, many areas in the central and Central Highlands regions are facing water shortage for rice and coffee watering.

 

The current water levels in the Ve, Tra Khuc and Tra Con rivers in Quang Ngai Province are nearly 40 centimeters lower than the levels recorded in the year-ago period. The risk of lacking water for dozens of thousands of hectares of summer-autumn rice is high, Dao Minh Huong, deputy director of the provincial Department of Agriculture and Rural Development, told the Daily on Tuesday.

 

If the water levels are 30-40 centimeters lower than 2012, there will be a serious water shortage, Huong added.

 

Quang Nam Province is also facing high risks of drought and saltwater intrusion in downstream areas of the Vu Gia, Thu Bon and Ban Thach rivers due to low rainfall and water storage at hydropower reservoirs.

 

Meanwhile, coffee farmers are lacking water.

 

Nguyen Van Tan, a farmer in Lam Dong Province’s Di Linh District, said that farmers in the area were lacking around 30% of the water demand. With current weather conditions, water for watering in the middle of next month will be scarcer, according to Tan.

 

However, in Khanh Hoa, Binh Dinh and Dak Lak provinces, water stored in reservoirs since late last year is still abundant, according to the provincial authorities.

 

According to the National Center for Hydro-meteorological Forecasting, there will be severe drought in downstream areas in the central region this month and next month.
