The Looming Environmental Catastrophe in the South China Sea

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

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

“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”

The Ministry of Agriculture and Rural Development (MARD) has warned that the fishing output has exceeded the permitted limit by 30 percent, especially aquatic creatures of the bottom layer. While the average permitted exploitation limit is 2.45 million tons a year, the total exploitation output has reached 3.1 million tons.

The MPA officers have the right to detain individuals who commit violations of MPA rules.

Nguyen Chu Hoi, former deputy director general of the Vietnam Administration of Seas and Islands, said that sea turtles live in many habitats and ecosystems during migration and development. The presence of sea turtles is considered one of the indicators of the health of the marine environment. Tiếp tục đọc “Marine Protected Areas given power to protect sea turtles”

The plan will map out sea-based socio-economic activities until 2035 in line with integrated management of sea and island resources and environment.

It focuses on marine environment and resources, the value of marine ecosystems and appropriate exploitation of the sea.

The plan is being built in accordance with the Việt Nam Law on Sea and the Law on Việt Nam’s Sea and Island Natural Resources and Environment. Tiếp tục đọc “Master plan to protect sea”
