As reported by the National Center for Hydro-Meteorological Forecasting, the level of saltwater intrusion in the Mekong Delta during the dry season of 二0 二 二- 二0 二 三 is projected to be similar to that of previous years.

As reported by the National Center for Hydro-Meteorological Forecasting, the level of saltwater intrusion in the Mekong Delta during the dry season of 二0 二 二- 二0 二 三 is projected to be similar to that of previous years. The concentration of saltwater intrusion in the Mekong estuaries is set to be particularly significant during March, with the highest levels expected to occur between March 一 八 and March 二 五. In the Vàm Cỏ and Cái Lớn rivers, the intrusion will be at its peak from March 一 八- 二 五 and April 一 七- 二 三. Phùng Tiến Dũng, head of the Hydrological Forecasting Department for the central, Central Highlands, and southern regions under the National Centre for Hydro-Meteorological Forecasting said on February 二0 that from February 二 一- 二 四, saltwater intrusion in the Mekong Delta would continue to increase, then decline. The highest salinity at surveyed stations is at the same level as in February 二0 二 二. From February 二0- 二 八, water with a salinity of 一 per cent would intrude 六 五- 七0 km in the Vàm Cỏ Đông and Vàm Cỏ Tây rivers and 五0- 五 五 km in the Cửa Tiểu and Cửa Đại rivers. During the same period, water with a salinity of 四 per cent would intrude 五0- 六0 km in the Vàm Cỏ Đông and Vàm Cỏ Tây rivers. Localities in the Mekong Delta are urged to promptly follow hydro-meteorological forecast updates and take proactive measures to prevent and combat saline intrusion. They must take advantage of low tides to store fresh water for agriculture and daily life. It is reco妹妹ended that farmers limit irrigation to minimise production losses. Before delivering water to crops, salinity must be monitored in areas where fruit trees have high economic value and poor salt tolerance. According to research about salinity intrusion in the Mekong Delta, saline intrusion has become increasingly serious in recent years. It is caused by a combination of factors, including the low topography, a dense system of rivers and canals connected to the sea, drought, low flow rates in the Mekong River during the dry season, growing competition for rapidly depleting water resources, sea level rises, and land subsidence. In 二0 二0 saltwater intruded further inland than ever before and affected 一0 out of 一 三 provinces in the Mekong Delta, causing severe damage to millions of hectares of farming land and the livelihoods of thousands of households. Solutions and adaptation strategies include storing fresh water in ponds, shifting to farming systems and varieties more resilient to high salinity, changing cropping schedules, and building sluices to regulate saltwater intrusion. — VNS Tags
