Salt water intrusion to Mekong estuaries forecast to increase in March
Saltwater intrusion is expected to increase in Mekong estuaries in late March while Vam Co and Cai Lon rivers in the South of Vietnam will see major saltwater intrusion until late April.

Hanoi (VNA) – Saltwater 🦩intrusion is expectedto increase in Mekong estuaries in late March while Vam Co and Cai Lon riversin the South of Vietnam will see major saltwater intrusion until late April.
According to the National Center for Hydro-MeteorologicalForecasting, the saltwater intrusion in theMekong Delta in the dry season of 2022-2023 is roughly on par with the average levelof the past years. Major saltwater intrusion in the Mekong estuaries will beconcentrated in March, particularly from March 18 to March 25. In the Vam Co andCai Lon rivers, major intrusion will occur from March 18-25 and April 17-23. Phung Tien Dung, head of the Hydrological ForecastingDepartment for the Central, Central Highlands, and Southern regions under theNational Centre for Hydro-Meteorological Forecasting said on February 20 thatfrom February 21-24, saltwater intrusion in the Mekong Delta will continue toincrease, then decline. The highest salinity at surveyed stations is at the samelevel as that in February 2022. From February 20-28, saltwater with a salinity of 1% will intrude 65-70 km in the Vam Co Dong and Vam Co Tay rivers, 50-55 km in the Cua Tieuand Cua Dai rivers, 60-65 km in the Ham Luong and Co Chien rivers, 55-60 km in the Hauriver and 25-30km in the Cai Lon river. During the same period, 4% saltwater will intrude 50-60 km in the Vam Co Dong and Vam Co Tay rivers, 40-48 km in the Cua Tieu and Cua Dai rivers,50-56 km in the Ham Luong and Co Chien rivers, 40-45 km in the Hau river, and 20-25 kmin the Cai Lon river.

Localities in the Mekong Delta are urged to promptly followhydro-meteorological forecast updates and take proactive measures to preventand combat saline intrusion. They need to take advantage of storing fresh water at lowtide for agriculture and daily life. It is recommended that farmers limit irrigation to minimiseproduction losses. Before delivering water to crops, salinity needs to be monitored in areas where fruit trees have high economic value andpoor salt tolerance./.
Prime Minister Pham Minh Chinh demanded Ben Tre further tap into its advantages and develop the sea-based economy, while addressing a working session with officials of the Mekong Delta province on February 16.
Mariam Sherman, World Bank Country Director for Vietnam, Laos, and Cambodia, said the World Bank remains committed to working with the Vietnamese government to develop the next phase of climate resilience and transformation for the Mekong Delta.
Under the directive, the PM instructed relevant agencies to regularly inspect, supervise and proactively implement disaster prevention, response and rescue measures in line with their assigned roles and mandates, ensuring readiness, avoiding passivity or delays, and maintaining operational continuity amid ongoing political and administrative restructuring at levels.
According to Dr. Vu Anh Tuan, Deputy Director General of the Vietnam Space Centre and head of the project, this is the first study in Vietnam to simultaneously employ Sentinel-2 satellite data, advanced machine learning algorithms, and the Google Earth Engine (GEE) cloud computing platform to model and monitor key seawater quality parameters.
The Deposit Return System is seen as a potential instrument for effectively advancing Vietnam’s vision of a circular economy, as outlined in Article 142 of the 2020 Law on Environmental Protection.

Young people should not view AI as salvation but rather as a tool under human control. Young creators should focus on learning and accumulating practical knowledge, using AI as a tool to carry out artistic projects in the most effective and cost-efficient manner.
Saigon Hi-Tech Park’s ambitious 50% renewable energy goal far exceeds the city’s 15% target, positioning the park as a trailblazing “living lab” for sustainable energy solutions.
Vietnam's economic losses from natural disasters are estimated to account for 1 to 1.5% of GDP annually - a steep price that will continue to rise unless the country takes strong action.
Wutip, the first storm in the East Sea so far this year, has wreaked havoc across central Vietnam, claiming lives, displacing residents, and causing widespread damage to houses, crops, and infrastructure, the Department of Dyke Management and Disaster Prevention and Control reported as of 6:30 pm on June 13.
The tremor occurred at 7:39:46 am (Hanoi time), with the epicentre located at latitude 14.924°N and longitude 108.236°E, at a depth of approximately 8.1 kilometres. The natural disaster risk level was classified as 0 – the lowest on the scale.
Addressing a session on “Accelerating Financing for Resilience: Tailored Solutions for Disaster Risk Reduction,” Deputy Minister Hiep emphasised Vietnam's proposal in building sustainable financing in response to natural disasters, which aligns with the Sendai Framework for Disaster Risk Reduction's goals.
Vietnam has demonstrated its strong commitments by participating in global sustainable development forums, signing multiple free trade agreements, and attracting support from international partners for the implementation of the SDGs.
The fight against plastic pollution could not succeed through isolated efforts, but it must be a collective endeavour involving the entire political system, businesses, citizens, and the international community, said Minister of Agriculture and Environment Do Duc Duy.
Lang Son Global Geopark, with its outstanding geological values, cultural heritage, and unique natural landscapes, represents a valuable addition to UNESCO’s global geoparks system.
In 2019, Quang Ninh became one of the first localities in Vietnam to launch a province-wide campaign against plastic waste, mobilising the participation of the political system, the business sector, and the general public. Other localities—such as Hai Phong, Da Nang, Binh Duong, and Ho Chi Minh City—have also effectively implemented waste-sorting initiatives at source, along with models for plastic-free markets and urban areas.
