The Mekong Delta is facing significant agricultural threats due to the El Niño climate pattern. Initial forecasts indicated that the pattern could persist through 2027, bringing higher temperatures, reduced rainfall, increased pest pressure, and salinity intrusion to Vietnam's primary rice-producing region.

As the situation progressed, hydrological forecasts highlighted a high probability of El Niño returning by the end of 2026, leading to a significant decrease in rainfall and river flow throughout the basin. Water levels at key stations, including Tan Chau and Chau Doc, were expected to remain below historical averages, while water levels at Cambodia's Tonle Sap also declined faster than usual. In response to these drought and saltwater intrusion risks, water resource management authorities activated contingency scenarios to protect agricultural production.
