Vietnam; Saltwater Intrusion in the Mekong Delta

 
In the Mekong Delta, saltwater intrusion causes huge losses to rice and vegetable farmers, and shrimp farms are one of the biggest contributors to the problem.  As they channel more and more saline water to their inland ponds, whole regions become unable to grow traditional crops.
 
In Hau Giang Province, shrimp farming has resulted in a severe shortage of freshwater for 8,000 families and caused damage to nearly 20,000 hectares of rice crops.
 
In Soc Trang Province, since mid-April 2009, saltwater intrusion has damaged some 10,000 hectares of paddy fields.  Rice seedlings on a further 5,000 hectares are currently delayed because of the salt concentration.
 
In Bac Lieu Province, over 25,000 hectares of paddy fields are flooded by saltwater, among them, more than 7,000 hectares of summer-autumn crops have been destroyed.
 
In Khanh Lam Commune in U Minh District of Cau Mau Province, saltwater has intruded into large areas of agricultural land.  Local farmers cannot plough the soil.  They can’t plant new crops.  They are facing huge losses because of low productivity.  To iron out the problems, Ca Mau has approved 23 irrigation projects, with a total investment of $225 million dollars, but so far, only four projects have received $6.2 million.
 
In 2006, the Ministry of Agricultural and Rural Development helped Bac Lieu and Soc Trang provinces start a $37 million irrigation project.  More than 60 drainages and dykes were built to prevent saltwater intrusion and to ensure enough fresh water for 150,000 hectares of rice.  Leaders in the two provinces, however, said that they only had enough funds to build one-third of the project and that construction has ground to a halt while they wait for more funds.  Thus far, the investment has not produced any results.
 
While waiting for the project to be completed, shrimp farmers continue to pump seawater into their ponds, causing further saltwater intrusion to some 60,000 hectares of land in the region.
 
Saltwater intrusion is also a big problem in Bangladesh.
