Hanoi (VNA) – A workshop on the application of satellitedata in monitoring pollution and research was held in Hanoi on December 1 aspart of the projects "Join hands for clean air” and “Improvingair pollution monitoring and management of Vietnam with satellitePM2.5 observation”.
The event was jointly organised by the Vietnam Live and Learn Centre forEnvironment and Community, the University ofEngineering and Technology under the Vietnam National University – Hanoi (VNU-UET), the Vietnam Clean AirPartnership (VCAP) andthe “Tia Sang” magazine of the Ministry of Science and Technology.
In recent years, the situation of PM2.5 fine dust in Vietnamhas been studied and published in reports and scientific journals by Statemanagement agencies, universities, institutes and scientists as well as a numberof social organisations.
However, reports and studies remain limited in terms of datasources due to the lack of monitoring data and exploitation of open datasources from satellites or sensor stations.
Inthis context, a report on PM2.5 fine dust matterin Vietnam in the 2019 -2020 period using multi-source data waspublished, giving a more complete picture of air pollution in both space andtime. This was the first report that provides information on the situation of PM2.5fine dust in all localities nationwide with data collected and analysed by standardmonitoring stations, sensors, and satellites.
Based on the report’s findings and referring to international experience, expertsdiscussed and proposed specific recommendations such as the application of multi-sourceapproach and computational model data from satellite images to monitor air quality, and development of detailed distribution mapsof PM2.5 fine dust in districts and townshíp in provinces and cities affected by PM2.5fine dust pollution,
Theyalso underlined the need to strengthen air quality monitoring stations meeting theS♑tate’s standards in localities across the country./.
The Ministry of Natural Resources and Environment (MoNRE) has asked the People’s Committees of centrally-run cities and provinces nationwide to roll out urgent solutions to control air pollution and promptly address any “hotspots”.
Prime Minister Nguyen Xuan Phuc has asked ministries and People’s Committees of centrally-run cities and provinces to step up the implementation of programmes and tasks on air quality control.
Ministries and sectors should work together and take drastic action to carry out Prime Ministerial Directive No 03/CT-TTg on enhancing air pollution control, Deputy Minister of Natural Resources and Environment Vo Tuan Nhan said at a meeting on January 28.
A seminar discussing measures to tackle environmental problems in the context of the Fourth Industrial Revolution (4IR) was held in Hanoi on March 27, in response to the Earth Hour 2021.
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.
