HCM City (VNA) - The University of Scienceunder the Vietnam National University-HCM City has set up the first greenhousegas monitoring station in the buffer zone of the Lang Sen Wetland Reserve inthe Mekong Delta province of Long An.
The station was set up with the co-operation of the university, Global ChangeResearch Institute and the Czech Academy of Science - CzechGlobe.
A ceremony to open the first greenhouse gas monitoring station was held at theUniversity of Science on May 9.
The station uses the eddy-covariance (EC) method which is widely applied influx research stations for different types of ecosystems around the world. Itquantifies the greenhouse gas balance and studies the dynamics of flux exchangeunder the changing climate and environment of irrigated rice fields in theMekong Delta.
The station officially began operating last month.
Nguyen Xuan Vinh, the station’s deputy head, said the equipment automaticallycollects and measures data on solar radiation, rainfall, soil and airtemperature, humidity, water level, and soil heat flux.
The data are transferred to the Research Centre for Greenhouse Gas and ClimateChange at the University of Science.
Monitoring for a sufficiently long period in paddy rice fields can provideenough information to help understand the carbon balance in the wetlandecosystem.
The ecosystem of paddy rice fields accounts for the largest area in the bufferzone of the Lang Sen Wetland Reserve, and contributes to discharge ofgreenhouse gas.
Under the impact of climate change and rising sea levels, rice farming systemsin the Mekong Delta have become hotpots of high vulnerability, and need tourgently adapt to climate change.
More extreme events due to climate change such as droughts and heat waves haveaffected the carbon cycle.
Data on greenhouse gas in the past was insufficient to develop strategies andmethods for control.
In the upcoming time, other stations for greenhouse gas monitoring will be setup in other areas of the Lang Sen Wetland Reserve.-VNA
Vietnam has actively implemented the Montreal Protocol and measures to reduce greenhouse gas (GHG) emissions to preserve the ozone layer, earning international recognition, said Deputy Minister of Natural Resources and Environment Le Cong Thanh.
Vietnam has called on countries around the world to raise the spirit of cooperation and harmonise their own interests with international concerns in coping with climate change.
Vietnam remains fully committed to international actions to fight climate change, said Pham Van Tan, Deputy Director of the Meteorology, Hydrology and Climate Change under the Ministry of Natural Resources and Environment.
A variety of measures to help the Mekong Delta region better respond to climate change and achieve sustainable agricultural production were proposed at a seminar on December 20 in Long An province, part of the third Vietnam Rice Festival.
The adoption of climate-smart agriculture (CSA) will improve the productivity and quality of agriculture, increase farmers’ incomes and reduce their vulnerability to adverse climatic phenomena, according to experts.
A workshop held in Hanoi on May 9 highlighted the need to adjust the Support Programme to Respond to Climate Change (SP-RCC) to better suit the current situation.
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.
Its Forest Protection Sub-department has applied various specialised software and information technologies in forest management and protection and fire prevention.
