Mekong Delta adapts to saltwater intrusion with new agricultural strategies

Authorities in the Mekong Delta of Việt Nam are implementing strategies to mitigate saltwater intrusion during the dry season extending until April. The Southern Institute of Water Resources Research has projected that this year's intrusion levels will surpass the norm, affecting the delta's output of rice, fruits, and seafood. Coastal provinces are experiencing salinity levels of four grams per liter in major rivers, a measure exceeding the tolerance of most crops. In response, measures such as dredging irrigation canals, constructing saltwater prevention embankments, and enhancing freshwater supply facilities are being undertaken.

Kiên Giang Province, a significant rice producer in the delta, has dedicated over VNĐ118 billion to saltwater prevention initiatives. These include the repair of sluices and electric pump stations, and the construction of temporary embankments to block saltwater. The province has also been proactive in operating coastal sluices and water management systems to preserve freshwater. Additionally, to support households facing clean water scarcity, 6,755 plastic tanks have been distributed for water storage.

To raise awareness and prepare for weather-related challenges, the delta's 12 provinces and Cần Thơ City have intensified advocacy efforts. An Giang Province, for instance, is guiding residents to store and use freshwater efficiently, while Bến Tre Province has initiated training programs for farmers on coping with saltwater intrusion. Despite these efforts, saltwater intrusion caused significant crop losses last year, prompting farmers to adopt preventive measures like constructing temporary embankments around fields and storing freshwater.

Moreover, the delta is witnessing a shift in agricultural practices, with an increasing number of rice farmers turning to drought-resistant crops. In Tiền Giang Province, farmers have transitioned to cultivating vegetables on lands previously affected by saltwater intrusion, using advanced farming techniques to reduce costs and increase profits. This adaptation not only counters the impact of saltwater intrusion but also promises economic benefits for the region's agricultural sector.
