Mekong Delta: Saltwater intrusion tends to increase

The Cai Lon - Cai Be sluice system (Kien Giang) has come into operation, helping hundreds of thousands of hectares of agricultural land in the lower Mekong Delta stabilize and proactively produce.

The Southern Institute of Water Resources Research stated that water storage in hydropower plants in the Mekong basin is currently higher than in the same period in 2023 and 2024. The reduction in water discharge from Chinese hydropower plants since April 7 has affected the downstream of the Mekong Delta.

It is forecasted that saline intrusion will last until the end of May 2025. For the upper Mekong Delta, water resources are sufficient, the main difficulties are in the high mountainous areas of Tinh Bien and Tri Ton, so it is necessary to implement measures to store water and save water. The middle Mekong Delta needs to operate salinity control works properly and store water whenever possible. When taking fresh water or irrigating crops, it is necessary to strictly control the salinity regime, especially for fruit trees.

Particularly in the coastal areas of the Mekong Delta, unusual saline intrusion can affect water resources and production in coastal irrigation systems such as Go Cong, North Ben Tre, and the coastal areas of Tra Vinh. Therefore, it is necessary to prepare response plans, store and use water reasonably.
