Major coral loss in Vietnam’s first marine protected area: Study

mongabay.com Keith Anthony Fabro 20 Jun 2025 VietnamOceans

  • Vietnam’s first marine protected area (MPA), Nha Trang Bay, has lost nearly 200 hectares (494 acres) of coral reef since it was established in 2002, according to a new study.
  • Major drivers of the coral decline include coastal development, warming sea temperatures and devastating crown-of-thorns starfish (Acanthaster planci) outbreaks worsened by overfishing and nutrient pollution.
  • The study calls for stronger conservation measures inside Nha Trang Bay and other MPAs, including pollution control, active reef restoration and inclusive community governance.
  • Experts say Nha Trang Bay offers lessons for other MPAs in Southeast Asia facing similar threats.

Vietnam’s first marine protected area, Nha Trang Bay, has lost nearly 200 hectares (494 acres) of coral reef since its creation in 2002, a new study shows. The alarming decline raises fresh questions about how effective conservation efforts have been in protecting one of the country’s most iconic coastal ecosystems.

NHA TRANG, Vietnam (AP) — The gentle waves off the coast of central Vietnam’s Nha Trang obscure an open secret: The life-giving coral reefs below are dying. The waters are eerily devoid of fish. The bounty of the ocean is coming to an end.

This is why Binh Van — who fished in these waters for over two decades — now charters his boat to Vietnamese tourists wanting to experience the thrill of fishing in the deep waters of the South China Sea. But there is only squid, which is flourishing in oceans warmed by climate change, to catch. His passengers don’t mind as the boat moves away from Nha Trang’s twinkling beach resorts. But Van is pensive.

It wasn’t always like this. There was a time when he’d catch 70 kilograms (154 pounds) of fish, like tuna and grouper, in one night. He can’t make money on the squid.

“Now I usually go home empty-handed,” he said.

Reclamation: A flawed solution

beaneaththesand.earth

A deep dive into the rationale behind some of Asia’s reclamation projects, the toll they take on our environment and communities, and the search for more sustainable alternatives.

Reclamation is seen as a solution for countries to deal with increasing land demands, by expanding their territory and rehabilitating previously uninhabitable lands or seas. Yet, the process guzzles an alarming amount of sand, causing massive environmental damage as well as a rise of transnational criminal syndicates trading in illegal sand.

Coastlines, ecosystems, and entire populations are now facing adverse impacts due to increased sand-mining activity, with one of the major driving forces being land reclamation. This practice of creating new land at sea is often touted as a solution to urban expansion and climate change.

Vietnam becomes one of first nations to sign High Sea Treaty

Vietnam becomes one of first nations to sign High Sea Treaty

Minister of Foreign Affairs Bui Thanh Son signs the High Sea Treaty, a United Nations agreement on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction. Photo by Thu HongVietnam on Wednesday signed the United Nations agreement on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, the High Sea Treaty.

The signing by Minister of Foreign Affairs Bui Thanh Son made Vietnam one of the first countries to sign the international-legally binding instrument under the 1982 United Nations Convention on the Law of the Sea (UNCLOS). It conveyed the message that Vietnam is a positive and responsible member of the international community as well as the country’s efforts to join hands with countries to deal with global issues, contributing to peace, prosperity and sustainable development.

More than 60 countries are scheduled to sign the agreement during the underway high-level week of the 78th UN General Assembly.

Vietnam’s desolate seabed

As coral reefs and marine life disappear, efforts to save them are underway, but is it too late?

NHA TRANG, VIETNAM ― In Hon Chong, one of Vietnam’s last coral reefs, colorful schools of fish have become distant memories. These days, only small fish lurk behind bleached coral formations, a stark difference from the way some travel brochures depict the place.

Half an hour by boat from Hon Chong is Hon Mun, a marine conservation site once home to more than 340 coral species, and valued at approximately US$70 million for its biodiversity in 2005.

About 10 years before the Covid-19 pandemic, professional divers started noticing a gradual depletion of the coral reefs in the area. They had hoped that lockdowns and border closures would alleviate stress from tourism and revive the reef.

“After two years [of Covid-19], I was speechless to see the ocean bed so empty, the coral all bleached,” photographer Na Son, a diver who has made hundreds of trips down to Hon Mun’s ocean bed, told Mekong Eye in June 2023. Last June, Na Son was one of many divers who spoke to local media about Hon Mun’s alarming coral depletion.

Coral reefs are considered to be one of Vietnam’s national treasures, as the country boasts one of the world’s most diverse ecosystems with 355 species, according to data from the World Resources Institute.

Yet across the country, vital coral reserves are depleting at such an alarming rate that frenzied attempts to salvage what remains are likely to be insufficient to restore the ecosystems.

The Looming Environmental Catastrophe in the South China Sea

Heated maritime and territorial disputes conceal the severe damage being done beneath the waves.

thediplomat.com

By Murray Hiebert January 14, 2022   

Much of the focus on the South China Sea over the past decade has centered around the nationalistic territorial disputes between China and four Southeast Asian claimants and a geopolitical tussle between China and the United States over freedom of navigation in the contested waters. What is going on beneath the surface of the sea – overfishing, destruction of coral reefs, climate change, plastics pollution, ocean acidification – is equally threatening and may have a longer-term impact on the survivability of the sea with its rich fishing beds, potential gas and oil reserves, and bustling sea lanes.

Hiện tượng thủy triều đỏ trên các vùng biển và đề xuất với Việt Nam

T.S Dư Văn Toán

thiennhien.net

“Thuỷ triều đỏ” là thuật ngữ ngày càng phổ biến và quen thuộc. Nó không thuần chỉ là một hiện tượng tự nhiên tuyệt vời đầy kì bí như nhiều người vẫn nghĩ mà thực chất là một vấn đề môi trường nhức nhối cần quan tâm.

“Thủy triều đỏ” chỉ sự nở hoa của các loài vi tảo biển. Đây là hiện tượng tự nhiên xảy ra do mật độ tế bào vi tảo gia tăng lên đến hàng triệu tế bào/lít (thông thường có khoảng 10 – 100 tế bào vi tảo/ml nhưng trong trường hợp “nở hoa”, mật độ có thể lên trên 10.000 tế bào/ml), làm biến đổi màu của nước biển từ xanh lục đậm, đỏ cho đến vàng xám.

Plankton decline hits marine food chain

DW_Plankton is the basis for the entire marine food web – and it is under threat. From the Mediterranean to the Pacific, animals have been struggling to survive, due apparently to changes with plankton.

Food chains represent the greatest interdependency within the webs of life. The marine food chain, for instance, is essential for oceans – and depends on plankton. But environmental changes and human activities may be threatening plankton– and therefore all marine animals.

According to a recent study,the biomass of sardines and anchovies has been decreasing at alarming rates in the Mediterranean Sea. At the same time, sea lions are struggling to forage on the coasts of California. Both cases have shed light on how a single food chain element can affect all others.

While it is still unknown whether species will be able to adapt to new conditions, the marine food chain is already experiencing drastic changes – and plankton plays a crucial role across the board.

“If anything happens to the plankton, an immediate cascade effect will take place on the food chain,” Ivan Nagelkerken, a University of Adelaide’s biology professor, told DW.

Building blocks of life

Plankton are tiny aquatic organisms that drift through the sea, forming the basis of the marine food chain.

For plankton, both quantity and quality – in terms of nutrients – affect life up the food chain. Tiếp tục đọc “Plankton decline hits marine food chain”
