# Vietnam drought and saltwater intrusion risks > Live situation record from CLSTR: https://clstr.news/situations/vietnam-drought-and-saltwater-intrusion-risks > Updated: 2026-09-11T05:51:00.000Z. Sources: 4. Developments: 2. Authorities in Vietnam are preparing for severe drought and saltwater intrusion expected during the 2026-2027 dry season, driven by a persistent El Nino phenomenon. In Dong Thap, forecasts indicate temperatures may rise by 0.5 to 1 degree Celsius above historical averages, with the rainy season potentially ending earlier than usual. Reduced rainfall and declining Mekong River flows increase the risk of salinity reaching up to 80km inland on the Tien River. Experts warn the situation could mirror the severity of the 2015-2016 period, threatening agriculture and domestic water supplies. In Tay Ninh, provincial officials are developing emergency response plans to manage high-risk scenarios. Measures include monitoring water levels on the Vam Co Dong and Vam Co Tay rivers, managing irrigation systems, and operating sluice gates to store freshwater. The province is also prioritizing forest fire prevention and technical guidance to protect livestock and crops from saline water. ## Timeline ### 2026-09-11: Tay Ninh develops drought and salinity intrusion response plans Tay Ninh province is preparing high-risk response plans for the 2026-2027 dry season to mitigate drought and saltwater intrusion affecting agriculture and water supplies. 2 sources. https://clstr.news/cluster/tay-ninh-develops-drought-and-salinity-intrusion-response-plans ### 2026-08-23: Dong Thap prepares for severe drought and saltwater intrusion Dong Thap province is preparing for severe drought and saltwater intrusion in the 2026-2027 dry season, driven by a strong El Nino and reduced Mekong River flows. 2 sources. https://clstr.news/cluster/dong-thap-prepares-for-severe-drought-and-saltwater-intrusion --- Cite as: Vietnam drought and saltwater intrusion risks.
