Mekong Delta (VNA) – The Mekong Delta, known for its fertility and rice fields, has been facing enormous challenges posed by climate change and upstream activities, according to environmental officials.
The Mekong Delta, with 𒊎an area of 3.96 million hectares and a population of 18 million, contributes50 percent of Vietnam’s t🌜otal food output. The region provides 90 percent of the country’s export rice, 70 percent of fruit and 65 percent of aquatic products.
Nguyen Xuan Hien, Director of the Southern Institute for Water Resources Planning (SIWRP) , said the region’s diverse natural resources range from fresh water and saline water to soil and abundant plant and animal species.
Climate change events such as sea water rise, drought andsaline intrusion as well as upstream activities have been eroding these advantages, which may cause heavy economic lossesand threaten local people’s livelihoods.
Minister of Natural Resources and Environment Tran Hong Ha said the Mekong Delta is one of the five deltas most vulnerable to climate change in the world.
According to the World Bank’s assessment, Vietnam is one of the five countries hardest hit by climate change, with aone-metre rise in sea levels likely to affect 10 percent of population and cause losses equal to 10 percent of GDP in delta regions.
The consequences of climate change to Vietnam are serious and will threaten the country’s efforts to reduce poverty and achieve sustainable development.
Water resources, agriculture and food security, health, deltas and coastal areas will be impacted most by the phenomenon.
Associate Prof. Dr. Tran Hong Thai from the National Hydro-Meteorological Service, said economic activities in the upstream Mekong River would alter the water current and volume in the region in an unpredictable way.
Hydro-electric dams in the upstream Mekong River will cause water shortages in the dry season and floods in the rainy season.
Thai said the water volume in the dry season may fall by 30 billion cu.m and climate change could cause water shortages or increase flooding.
The Mekong Delta includes Can Tho city and 12 provinces - Long An, Dong Thap, Tien♈ Giang, Vinh Long, TraVinh, Ben Tre, An Giang, Hau Giang, SocTrang, Bac Lieu, Ca Mau and Kien Giang. - VNA
Communication work plays the leading role in climate change response as public awareness of this issue still remains inappropriate, said Prime Minister Nguyen Xuan Phuc.
President Tran Dai Quang asked for Japan’s continued assistance in responding to climate change, especially drought and saline intrusion in the central, Central Highlands and southern regions.
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.
Renowned artists including Ha Anh Tuan, Den Vau, and Phan Manh Quynh, along with many directors and attendees, took part in planting hundreds of rare tree species such as mun (Diospyros mun) and cho chi (Parashorea chinensis) in the Thung Bong area of the Cuc Phuong National Park, contributing to forest ecosystem restoration.
The dispatch noted that since the beginning of 2025, natural disasters have claimed 29 lives and left several others missing. A total of 67 houses have collapsed, and 2,342 homes have been unroofed or damaged.
