Mekong Delta most vulnerable to flooding because of sea level rise
An 80-cm rise in the sea level could leave 31.94 percent of the Mekong Delta permanently flooded, according to the 2020 version of the climate change scenario report recently released by the Ministry of Natural Resources and Environment (MoNRE).

Hanoi (VNA) – An 80-cm rise in the sea levelcould leave 31.94 percent of the Mekong Delta permanently flooded,according to the 2020 version of the climate change scenario report recentlyreleased by the Ministry of Natural Resources and Environment (MoNRE).
The risk of flooding caused by sea level rise will be likelyto increase on account of a combination of different factors, from geologicaluplift, subsidence, to tides and storm surges.
Land subsidence has been adversely affecting the Mekong Deltaand Ho Chi Minh City which have the lowest elevation in the country.
Data from the MoNRE shows that the Mekong Delta is subsidingby an average 1cm per year, even up to 5.7cm per year in some locations, whilethe sea level rises around 3 – 5cm a year, said Assoc. Prof, Dr Le Anh Tuan,Deputy Director of the Research Institute for Climate Change at the Can ThoUniversity.
He suggested that the Mekong Delta and HCM City developscenarios and its consequences for different levels of sea rise and evaluatethe level of resilience associated with the surges. Southern localities must also develop roadmaps for adaption to sea level rise based ondifferent projections and have backup plans in case projections are exceeded, hesaid./.
The first phase of a 10 trillion VND (433.3 million USD) project to control flooding caused by tides in the Ho Chi Minh City has so far seen 90 percent of its workload completed, informed the investor Trung Nam Group on July 2.
The National Centre for Hydro-Meteorological Forecasting under the Vietnam Meteorological and Hydrological Administration and HydroScan Company of Belgium signed a cooperation agreement on the transfer of real-time flood forecast technology for Hanoi’s inner areas.
Floods, loss of biodiversity and sea level rise are the top three perceived climate change impacts in Southeast Asia, according to a climate survey on regional people's attitudes and perceptions conducted by the ISEAS – Yusof Ishak Institute (ISEAS).
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.
The figures were highlighted in a Pre-Feasibility Study on a DRS tailored for single-use beverage packaging in Vietnam, conducted by Eunomia Research & Consulting.
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.
This year’s World Oceans Day on June 8 is themed 'Wonderful Oceans: Sustaining What Sustains Us', while World Environment Day is on June 5 with the theme: 'Beat Plastic Pollution'.
According to Director of the provincial Department of Agriculture and Environment Le Huu Toan, a fire prevention and control plan has been in place since the dry season began, including round-the-clock patrols and rapid-response teams to snuff out fires before they could spread.
