Long An: Salinity intrusion tends to increase in the second half of April.

According to forecasts from specialized agencies, in the latter half of April, saltwater intrusion in Long An province is expected to increase, especially in areas along the Vam Co Tay and Vam Co Dong rivers.

Specifically, the 4g/l salinity boundary – a threshold that can affect daily life and production – is predicted to penetrate more than 63km inland on the Vam Co Tay River and more than 65km on the Vam Co Dong River. A salinity level of 1g/l will penetrate up to 84km and 87km respectively on the two rivers.

The sluice gates are operated efficiently to prevent saltwater intrusion, store freshwater, and serve agricultural production.

According to Nguyen Quang Ngoc, Director of the Long An Provincial Meteorological and Hydrological Station: “Around mid-April, there will be a high level of saltwater intrusion , higher than the multi-year average but lower than in 2024. This is the peak of the drought and salinity season this year, and according to the Provincial Meteorological and Hydrological Station, the salinity will be between 0.4 and 0.6 parts per thousand.”

Given the situation, authorities advise people in high-risk areas to proactively store freshwater during low tides for agricultural production and daily life; and to limit irrigation and drainage during periods of high salinity to minimize the risk of damage. Especially in areas growing high - value fruit trees, people should regularly check the salinity level of the water before use to ensure the safety of their crops.

According to assessments, the level of natural disaster risk due to saltwater intrusion on the river system in Long An in the coming period is likely to be at level 3 , which is a high risk level requiring close monitoring.
