    Pacific island nations launch plan for world’s first Indigenous-led ocean reserve

    Pacific island nations launch plan for world’s first Indigenous-led ocean reserve

    The governments of the Solomon Islands and Vanuatu have announced their commitment to create a massive multinational [Melanesian Ocean Reserve](https://storymaps.arcgis.com/stories/82ea18c8f2874d8fa85ad572a844f52f). If implemented as envisioned, the reserve would become the world’s first Indigenous-led ocean reserve, covering an area nearly as big as the Amazon Rainforest. Speaking at the U.N. Ocean Conference underway in Nice, France, representatives of both countries said the vision for the ocean reserve is to cover at least 6 million square kilometers (2.3 million square miles) of ocean and islands. The reserve will include the combined national waters of the Solomon Islands, Vanuatu and Papua New Guinea, and extend to the protected waters of New Caledonia’s exclusive economic zone. All of the island countries, largely inhabited by Indigenous Melanesians, are located in the southwestern Pacific Ocean, within the region known as Melanesia. “The Melanesian Ocean Reserve will give the governments and peoples of Melanesia the ability to do much more to protect our ancestral waters from those who extract and exploit without concern for our planet and its living beings. We hope our Indigenous stewardship of this vast reserve will create momentum for similar initiatives all over the world,” Vanuatu’s environment minister, Ralph Regenvanu, said in a [joint press release](https://www.prnewswire.co.uk/news-releases/melanesian-leaders-announce-worlds-largest-indigenous-led-marine-reserve-302479997.html).

    A Deep-Sea Expedition Unearths Unimaginable Lifeforms in the South Sandwich Islands

    A Deep-Sea Expedition Unearths Unimaginable Lifeforms in the South Sandwich Islands

    A recent deep-sea expedition to one of the most remote locations on Earth, the South Sandwich Islands in the South Atlantic, has uncovered stunning new ecosystems surrounding hydrothermal vents. The discovery, which includes vibrant coral gardens and new species, was part of a 35-day mission aboard the [Schmidt Ocean Institute’sresearch vesselFalkor](https://schmidtocean.org/new-coral-gardens-hydrothermal-vents-found-south-sandwich-islands/)(too). This expedition is part of the Ocean Census project, a global initiative focused on documenting marine life before it is lost due to climate change, deep-sea mining, and other environmental threats. The scientific team faced severe challenges including subsea earthquakes, hurricane-force winds, towering waves, and icebergs, but their efforts were rewarded with groundbreaking discoveries. The expedition to the South Sandwich Islands revealed several hydrothermal vent systems previously unknown to science. These vents, which are located on the northeast side of the Quest Caldera, play a crucial role in deep-sea ecosystems. The research team was particularly excited to uncover a vibrant vermillion coral garden thriving near shallow hydrothermal vents around 700 meters deep (nearly 2,300 feet) on Humpback Seamount. While tropical coral reefs are often associated with warm waters, these cold-water coral gardens in the deep sea are a testament to the richness of marine life in unexpected environments.

    Indonesian women sustain seaweed traditions in a changing climate

    Indonesian women sustain seaweed traditions in a changing climate

    NUSA PENIDA, Indonesia — Storm clouds loom overhead as Nyoman Mitri peers out at rows of seaweed lines stretching across the shallow tidal waters of Nusa Penida. Her weathered hands move with practiced ease as she secures a strand of green seaweed to a rope. “It never used to be like this,” she says. “It’s only been the last 10 years or so that rain has begun to seriously damage the seaweed.” Ibu Mitri, or Mrs. Mitri, as she’s known by her community, is sharing her seaweed cultivation techniques with a few tourists. Together, they sort through fresh seaweed, discarding damaged strands and carefully tying healthy green ones onto lengths of rope, preparing them to be returned to the sea and fastened to wooden posts, where they’ll continue growing until the next harvest. As she ties hundreds of strands of seaweed back onto the lines, lulled into a methodical rhythm, she begins to share her concerns: the changing climate, increasing development, and the growing unreliability of each harvest. With a shy smile, she speaks of how increased rainfall and more frequent storms have threatened traditions once guided by the seasons, not by storms.

    Oceans: What if France’s future lay in its overseas territories?

    Oceans: What if France’s future lay in its overseas territories?

    The figures are well-known, but it’s worth recalling them. Thanks to its overseas territories, France today possesses the world’s second-largest exclusive economic zone (EEZ) behind the United States and ahead of Australia, with nearly 11 million km². A vast expanse that extends across all oceans. In the Atlantic with the Antilles, French Guiana and Saint-Pierre-and-Miquelon, in the Indian Ocean with Réunion, Mayotte and the Scattered Islands, in the Pacific with New Caledonia, Polynesia, and Wallis and Futuna. France is also present in Antarctica with the TAAF, the French Southern and Antarctic Territories (Crozet archipelago, Kerguelen, Amsterdam and Saint-Paul). This presence allows France to be the only nation in the world to have territories in all major oceans, except the Arctic. The United Kingdom also possesses several overseas territories such as Bermuda, Gibraltar or the Falklands, but its presence is not as extensive across all oceans. The United States has a strong presence in the Pacific with notably Hawai’i and American Samoa, in the Atlantic with Puerto Rico and the Virgin Islands, but not in the Indian Ocean. This presence in the three major oceans of the planet gives France a strategic role in international negotiations on the exploitation of marine resources, biodiversity, and the fight against piracy and illegal fishing. “We must fully grasp the importance of this maritime domain. First is the United States, second Australia, but we clearly understand that the United States and Australia achieve this through the size of their mainland territories, which is absolutely not the case for our country. Exactly 96% of France’s maritime domain relies on its overseas territories. And therefore, the overseas territories are France’s great opportunity, and also that of the European Union. But this incredible potential only wears out if we use it,” indicates Christian Buchet, historian and geopolitician, specialist in seas and oceans.

    Small island states should lead, not just participate, in ocean-related scientific research

Though they are the custodians of 30 per cent of the ocean under national jurisdictions, small island states lead just 0.3 per cent of UN-endorsed decade of action projects on ocean health, said Singapore’s Foreign Minister Vivian Balakrishnan on June 9. Ocean decade actions are science-based programmes, projects or activities endorsed by the UN to improve ocean health. “Small island developing states have been the subjects of ocean research for too long, the observation points in data sets, the case studies in reports, and the vulnerable communities in impact assessments,” Dr Balakrishnan said on the first day of the [UN Ocean Conference](https://www.straitstimes.com/world/world-leaders-head-to-france-for-un-summit-on-ocean-threats) in Nice, France.

    Environmental DNA, a ‘revolutionary’ key to unlocking the secrets of our oceans

    Environmental DNA, a ‘revolutionary’ key to unlocking the secrets of our oceans

    Pierre Jorcin slides on a pair of gloves, attaches a plastic tube to a filter, plunges it into the water, presses the start button on a small pump and then slowly begins walking through the river stream. Thirty minutes later, he has gathered three litres of water and filtered thousands of particles. The entire procedure seems simple, banal even. But Jorcin’s gesture is part of a microscopic revolution. In the process, the scientist has collected fragments of [environmental DNA](https://www.france24.com/en/live-news/20210907-the-world-in-a-drop-of-water-dna-tool-transforms-nature-tracking), also known as eDNA. “Every living organism leaves traces of DNA behind, whether in water, soil or in the air. And those traces hold out for some time before eventually degrading,” Jorcin explains. “By collecting them, we can identify and catalogue the organisms we find like bacteria, mammals, amphibians, fish, etc.”

    Value oceans, don’t plunder them, French Polynesia leader tells AFP

    The archipelago in the far South Pacific Ocean, an overseas territory of France, is led by Moetai Brotherson, who believes oceans should be valued, not plundered. President Brotherson spoke with AFP about deep-sea mining, ecological stewardship, and his dream of a day where environment summits are no longer needed. A: “It covers our entire exclusive economic zone, approximately 5 million square kilometres (1.93 million square miles). From north to south, that’s equivalent to the distance between Stockholm and Sicily, and from east to west, it’s Romania to Portugal.

    ‘Madness’: World leaders call for deep-sea mining moratorium at UN ocean summit

    ‘Madness’: World leaders call for deep-sea mining moratorium at UN ocean summit

    This story was supported by the Pulitzer Center’s Ocean Reporting Network, where Elizabeth Claire Alberts is a fellow. NICE, France — At the 2025 U.N. Ocean Conference (UNOC), taking place in Nice, France, between June 9 and 13, world leaders renewed their call for a global moratorium on deep-sea mining, an emerging industry that many experts say could seriously and irreversibly damage marine ecosystems. At the opening plenary, French President Emmanuel Macron denounced deep-sea mining as “madness.” He described the prospective industry as a “predatory” activity that threatens to destroy the seabed and potentially release stored carbon. France was among the first countries to take a stand against deep-sea mining, calling for a [ban](https://news.mongabay.com/2022/11/frances-macron-joins-growing-chorus-calling-for-deep-sea-mining-ban/) in 2022.

    Cabo Verde – Mãezinha of Rincão: A woman of the sea, a voice for her community

    In the quiet fishing village of Rincão, on the western coast of Santiago Island in Cabo Verde, Maria Sábado Horta Fidalgo, known to everyone as Mãezinha, is more than just a fishmonger. She is a boat owner, community leader, advocate for sustainable fishing, and a woman determined to chart her own course through hardship and hope. At 44, Mãezinha lives in a multigenerational household with her 86-year-old mother, her 8-year-old daughter, and her niece. Her eldest daughter, now 21, has emigrated. Together, they form the anchor of a life built around the sea, a business she inherited not just by circumstance, but by calling. “My name is Maria Sábado Horta Fidalgo, better known as Mãezinha” she quietly introduced herself,” as she sat on the rooftop of her small house facing the Atlantic Ocean. There, fishmongers, mostly young men and a few middle-aged women were busy divvying up catches brought ashore by fishermen. “I have two daughters… I’m a fishmonger, I have two boats,” she added.
