    Indonesian islanders plant mangroves, seek justice as seas rise

    Excerpt from context.news PARI ISLAND, Indonesia - Under the scorching midday sun, Asmania and several women from Indonesia's Pari Island walk toward Rengge Beach, a shoreline slowly receding from the rising sea, to plant dozens of young mangrove seedlings. The Women's Group of Pari Island hopes the mangroves, which also absorb planet-heating greenhouse gas emissions, will protect the coastline from worsening tidal floods, rising sea levels and stronger waves. "The sea is not like it used to be. It's hotter, rougher, and it scares us," said Asmania, a mother of three, as she dug with her hands into the sand beneath the shallow sea. Home to just 1,000 residents, Pari Island near the capital Jakarta is at the centre of a globally significant court case over the impact of climate change on its beaches. Asmania, who goes by a single name, and three other residents sued cement giant Holcim in Switzerland in 2023, accusing it of failing to cut emissions as their island faced repeated floods. Cement production contributes about 7% of the world's total carbon dioxide (CO2) emissions, according to the Global Cement and Concrete Association. A court in the town of Zug, where Holcim has its headquarters, has not yet ruled on whether to hear the case.

    Scientists are racing to save Madagascar’s iconic chameleons as flames close in

    Scientists are racing to save Madagascar’s iconic chameleons as flames close in

    Excerpt from vox.com I watched the fire from the edge of a dense forest in central Madagascar, a few hours northwest of Antananarivo, the country’s capital. It’s a special spot. This is one of the last remaining forests in the highlands of central Madagascar — a region devastated by decades of deforestation — and home to a raft of rare animals, including several species of chameleons. This forest, which contains more than 400 species of trees, only exists because the area has been protected for decades. It’s part of a park called Ambohitantely Special Reserve that has managed to limit illegal logging, clearing land for agriculture, and other forces that have razed the other forests here and across much of Madagascar.

    Voyage Into the Art of Finding One’s Way at Sea

    Photo credit: Chewy C. Lin via nytimes.com Excerpt from nytimes.com When leaving an atoll of the Marshall Islands, in the Pacific, Alson Kelen prefers to sail after sunset. It’s like navigating with his eyes closed — allowing him to feel the up, down and sideways movement of every swell. “That’s how the Marshallese navigate,” he said. “They navigate with their stomach.” For thousands of years, Marshallese navigators used traditional wave-piloting techniques to travel vast expanses of ocean. Wave piloting is the art of feeling and reading the swells and waves that hit and emanate from the region’s atolls. After a lifetime of studying these and other patterns, navigators pass a test devised by their chiefs to become a ri meto, or person of the sea.

    Island Homes Welcoming Back Over 7,000 ‘Glow-in-the-Dark’ Snails

    Island Homes Welcoming Back Over 7,000 ‘Glow-in-the-Dark’ Snails

    Excerpt from businessmole.com On Tuesday 18 November, 2025, the team behind a decades-long zoo project celebrated a major milestone in the recovery of ‘extinct’ snails. The team has successfully reintroduced thousands of ‘glow-in-the-dark’ snails to French Polynesia as part of a global conservation program to save the species from extinction. This annual reintroduction of zoo-bred Extinct in the Wild and Critically Endangered Partula snails marked the largest release of these finger-nail sized snails to date, with over 7,000 snails being returned to four islands. Before their release, each snail was marked with a small dab of white UV reflective paint, which glows blue under UV light. This marking method helps the team locate and monitor the snails, as they are most active at night.

    Main driver of Sargassum blooms in the Atlantic Ocean revealed

    Main driver of Sargassum blooms in the Atlantic Ocean revealed

    Photo credit: Arkadij Schell via Phys.org Excerpt from phys.org By the beginning of June this year, approximately 38 million tons of Sargassum drifted towards the coasts of the Caribbean islands, the Gulf of Mexico, and northern South America, marking a negative record. Especially during the summer months, the brown algae accumulate on beaches, decomposing and emitting a foul odor. This not only repels tourists but also threatens coastal ecosystems. In the open ocean, Sargassum seaweed floating on the surface serves as nourishment and habitat for numerous marine species.

    Documentary gives voice to the women of the sea in the Azores to protect the ocean.

    Photo credit: Ricardo Nogueira via SAPO.pt Excerpt from sapo.pt The documentary 'Women of the Sea - Azores' brings together the voices of 49 Azorean women with a "deep emotional connection" to the ocean, aiming to highlight the role of women and raise awareness about the protection of marine biodiversity. "We are seeing more and more women working at sea, developing businesses, providing training, and involved in technological and scientific development. The project ultimately gives women a voice. Women are naturally caregivers, and we need to take care of our ocean," filmmaker Raquel Clemente Martins explained to the Lusa news agency. The documentary, which features the voices of 49 women and involved a total of 71 women from the Azores, will be screened on November 7th at the Pavilhão do Conhecimento (Knowledge Pavilion) in Lisbon, during the National Ocean Literacy Conference, after having premiered on Faial Island in July.

    American Samoa says no to deep-sea mining. The Trump administration might do it anyway.

    American Samoa says no to deep-sea mining. The Trump administration might do it anyway.

    Photo credit: David Briscoe / Associated Press via ICTNews.org Excerpt from ictnews.org In early August, in the village of Utulei on the eastern shore of Tatuila, the largest of seven islands that make up American Samoa, more than two dozen local residents gathered in an auditorium. They were there to learn about a proposal to allow deep-sea mining across more than 18 million acres of their surrounding waters in the Pacific Ocean. President Donald Trump had issued an executive order to jump-start the nascent deep-sea mining industry three months earlier. Within weeks, the U.S. Department of the Interior began asking for public input on leasing the seabed surrounding American Samoa, and the territorial government organized a series of meetings to help educate the public on what to expect.

    Pacific protesters against deep sea mining challenge US exploration ship

    Photo credit: Robin Hammond / Greenpeace via AsiaPacificReport.nz Excerpt from asiapacificreport.nz Cook Islanders holding a banner reading “Don’t Mine the Moana” have confronted an exploration vessel as it returned to Rarotonga port today, protesting the emerging threat of seabed mining. Four activists in kayaks paddled alongside the Nautilus, which has spent the last three weeks on a US-funded research expedition surveying mineral nodule fields around the Cook Islands in partnership with the Cook Islands government. The Nautilus expedition comes just six months after President Donald Trump signed an Executive Order to expedite deep sea mining, tasking the National Oceanic and Atmospheric Administration (NOAA) to fast track the licensing process.
