Dr Le Xuan Sinh from Hai Phong-based Institute of Marine Environment and Resources said that green economies helped improve living standards and social equality as well as reducing environmental risks and ecological deficiencies.
Sinh said that people living on islands often faced disadvantages in economic conditions, healthcare, education and other public services.
He said economic activities were usually spontaneous and did not follow any sustainable models. This resulted in poor quality of living standards or islanders were vulnerable to risks of natural disasters and diseases.
“The disadvantages are why there is migration to the mainland. Islands often cannot attract people to live there,” Sinh said.
“Once green economic models are implemented, islanders could better their livelihood and their resilience to climate-change impacts," Sinh said.
"Or at least, they could manage by themselves for a time if the islands are isolated because of natural disasters,” Sinh said.
He said that it was necessary to develop green economy models accompanied by green production and services. Environmental conservation and protection would also ensure bio-diversity in order to have sustainable development.
In addition, aquaculture production must use advanced environmentally friendly technologies while eco-tourism should be made a key industry.
For example, Viet Hai island commune on the east of Cat Hai island district, is the third largest island in Vietnam. There are 88 families or 270 people living on the island, but there is no market. Agricultural production is small and spontaneous, unable to provide enough food for islanders. Most of the food is from the mainland.
Sinh said that the island commune should concentrate on community tourism or home-stay accommodation to take advantage of its location in Cat Ba Nature Reserve. Organic agriculture was another option.
Meanwhile, he said Nhon Chau island commune in the central province of Binh Thuan should take advantages of its beautiful beaches. Eco tourism with sight seeing, diving and fishing would attract visitors. High-tech agriculture should be applied to provide enough food to islanders and visitors as 90 percent of soil on the island is unproductive.
According to the Ministry of Natural Resources and Environment, Vietnam has more than 3,000 islands and islets with a total area of about 1,700 sq.km. Of those, three islands have more than 100 sq.km each, including Phu Quoc island in southern Kien Giang province, Cai Bau island in Quang Ninh province and
Cat Ba island in Hai Phong city. Twenty three islands have an area of 10 sq.km, 82 islands have 1 sq.km each. About 1,400 islets have not been named.
Groups of islands are said to have potential to become marine economic hubs and logistic centres for on-sea activities, including fishing or tourism. The islands together can create strategic areas to boost socio-economic development, ensure national defence and security.
Island economies could become “pillars for development” spreading development to surrounding areas. In addition to values of landscapes, the marine resources around the islands are crucial to fishing industry and sea tourism.
While more than 200 islands and islets in the country are said to be livable, just 66 have residential areas with populations in 2010 of about 240,000 people.
There are another 2,800 islands and islets unsuitable for human daily life or production.
(seafood.vasep.com.vn) Vietnam’s pangasius exports have shown encouraging signs of recovery in 2026. In the first four months of the year, total export turnover reached USD 720 million, up 17% compared to the same period last year. This result reflects improving demand across many markets, as well as the efforts of Vietnamese pangasius enterprises to maintain production, secure orders, and adapt to changing market conditions.
(seafood.vasep.com.vn) In the first four months of 2026, Vietnam’s tilapia exports reached USD 49 million, up 151% compared to the same period in 2025. This impressive growth reflects positive momentum in the tilapia sector, with Brazil emerging as a key driver of growth, while frozen tilapia fillets continued to be the industry's leading export product.
(seafood.vasep.com.vn) Vietnam’s tuna exports to the UK have shown positive signs in the first months of 2026. While the UK’s overall tuna imports from the world declined, imports from Vietnam increased strongly, indicating that there is still room for Vietnam to expand its market share. However, behind this growth, competitive pressure remains intense, especially as the UK continues to be a major market for established suppliers such as Ecuador, Mauritius, and Ghana.
(seafood.vasep.com.vn) Biofloc technology is being piloted in several rice–shrimp farming models in Ca Mau Province, showing initial positive results in controlling pond environments, improving shrimp seed quality, and supporting sustainable aquaculture development.
(seafood.vasep.com.vn) In the first four months of 2026, Mexico, Brazil, and Colombia together contributed USD 108 million to Vietnam’s pangasius exports, accounting for around 15% of the industry’s total export turnover. Amid tightening global whitefish supply and slowing demand in several traditional markets, Latin America is increasingly becoming an important expansion destination for the sector.
(seafood.vasep.com.vn) Alongside the development of high-tech shrimp farming, Ha Tinh Province is accelerating the cultivation of high-value freshwater aquatic species, with red tilapia emerging as an effective and sustainable farming model.
(vasep.com.vn) Vietnam’s tuna exports reached USD 81 million in April 2026, down 6% compared to the same period in 2025. In the first four months of the year, export turnover totaled USD 289 million, down 4.8%. Although the overall export picture has yet to brighten significantly, market trends are becoming increasingly diversified rather than moving in a single direction.
(seafood.vasep.com.vn) Vietnam’s pangasius industry is undergoing strong restructuring starting from the broodstock and fingerling segment in order to improve productivity, quality, and export competitiveness. This is considered a critical foundation for the sustainable development of the industry amid rising production costs and increasingly stringent market requirements.
(seafood.vasep.com.vn) According to Vietnam Customs data, pangasius exports in April 2026 reached USD 206 million, up 18% compared to the same period in 2025 — marking another consecutive month of double-digit growth since the beginning of the year. Cumulative pangasius export turnover in the first four months of 2026 reached USD 720 million, up 17% year-on-year, reflecting the positive growth momentum of this key export product.
(seafood.vasep.com.vn) Vietnam’s shrimp exports in the first four months of 2026 maintained positive growth momentum, reaching approximately USD 1.5 billion, up 15% compared to the same period last year. However, behind this result lies diverging trends across markets, as the global shrimp industry continues to face pressure from inflation, high inventories, price competition, and increasing trade risks.
