Small islands like Maldives may not disappear under rising seas, researchers find
In recent years, the leaders and inhabitants of many small-island nations like the Maldives, Kiribati and Tuvalu have warned that climate change is an existential threat to their homelands, fearing they could disappear under rising seas as the planet warms.
But according to research published on Wednesday, small, low-lying islands dotted around the Pacific, the Caribbean and Asia — often seen as the places most vulnerable to global warming — can naturally adapt and raise themselves above encroaching waves.
A three-year study led by Britain’s University of Plymouth, which looked at coral reef islands such as the Maldives and the Marshall Islands, found that tides move sediment to create higher elevation, a process that may keep the islands habitable.
“The dominant discourse is that of an island drowning, and the outcome of that is coastal defences and relocation … We think there are more trajectories for the islands,” said lead author Gerd Masselink, professor of coastal geomorphology at the University of Plymouth.
Low-lying island states are judged to be at greatest risk from increasingly powerful storms and rising oceans, with some making preparations to resettle their people within decades.
Many are already building sea walls, moving coastal villages to higher ground, appealing for international aid or setting up projects to repair damage caused by climate change impacts.
The world’s tens of thousands of coral reef islands are mostly uninhabited, but are home to about a million people who largely rely on fishing or tourism for a living, said Masselink.
Although the islands have different structures due to varying weather and wave patterns, they tend to be relatively small, low-lying, sandy or gravel islands sitting on top of a living reef platform.
They were formed hundreds of thousands of years ago by waves moving and piling up reef material or sediment to create higher ground — a natural defence mechanism that continues, he noted.
For the study published in the journal Science Advances, scientists built a model coral reef and island in a laboratory tank with rising water levels, and used computer simulations to replicate how such islands respond to higher seas in reality.
The results suggest that by opting for climate-resilient infrastructure that allows for occasional flooding, like buildings on stilts and movable houses, islanders with enough space could adapt to their shifting environment, Masselink said.
Dredging coral sand and sediments found in island lagoons and moving it to beaches could also aid the natural process of raising the islands, he told the Thomson Reuters Foundation.
Sea walls, however, are compromising the natural ability of the islands to adjust to rising sea levels, he said.
“If you stop the flooding of the islands, you also stop the movement of the sediment on top of the island,” he said.
Most coral islands do not depend on agriculture, and import food and fresh water, making saltwater contamination during flooding less of an issue, he noted.
Hideki Kanamaru, natural resources officer with the UN Food and Agriculture Organisation in Asia-Pacific, said the study provided a “new perspective” on how island nations could tackle the challenge of sea-level rise.
But even if islands can adapt naturally to higher seas by raising their own crests, humans still need to double down on global warming and protection for island populations, he added.
Climate change in Maldives
Maldives comprises 1,190 islands in 20 atolls spread over 900km in the Indian Ocean. Of these, just 199 islands are inhabited with a population of slightly over 515,000 people. The highest point of land is two metres or about six feet above sea level.
The atolls of Maldives are ringed by the seventh largest coral reefs in the world and among the richest in species diversity. The reefs host over 1,900 species of fish, 187 coral species, and 350 crustaceans.
Drawn by its pristine beaches, underwater coral reefs, and spectacular marine wildlife, this small island-nation attracts some 1.5 million tourists annually. In recent years, nature-based tourism has served as the engine of growth for the economy and accounts for about 70 per cent of GDP.
Geography has made the Maldives especially vulnerable to the consequences of climate change. Being land scarce and low lying, the country is exposed to the risks of intensifying weather events such as damage caused by inundation, extreme winds, and flooding from storms.
With the melting of polar ice caps, the Maldives is also exposed to the risks of sea-level rise.
Rising sea temperatures also threaten the coral reefs and cause bleaching and death, with the most severe damage in areas that are stressed by pollutants, or damaged by physical disturbance.
Vulnerability to climate change hazards has been magnified by damage to coral reefs which has in turn impaired their protective function, thus a negative cycle of impact.

Alila Kothaifaru Maldives marks June with sustainability and marine conservation initiatives
Alila Kothaifaru Maldives is reinforcing its commitment to environmental stewardship this June through a series of sustainability-focused initiatives and conservation experiences.
In celebration of World Environment Day on 5 June and World Ocean Day on 8 June, the management and team at Alila Kothaifaru Maldives took part in activities designed to promote awareness, education, and action in support of protecting the natural world, both above and below the waterline.
The programme began on World Environment Day, when team members came together for a tree planting activity on the island. Inspired by this year’s global theme, “Our Land, Our Future”, the initiative highlighted the vital connection between healthy ecosystems, biodiversity, and human wellbeing, while contributing to the resort’s ongoing efforts to preserve and enhance its natural environment.
Building on this momentum, the resort is continuing its sustainability journey throughout June with a series of marine conservation activities developed in collaboration with Euro-Divers Maldives. The programme began with Reef Awareness Day on 1 June, featuring a coral planting programme with the marine biologist. Participants contributed directly to reef restoration efforts while learning about the importance of coral ecosystems in maintaining ocean health.
On 8 June, guests and colleagues came together to mark World Ocean Day through a house reef clean-up dive and beach clean-up, helping to remove marine debris and protect the delicate reef ecosystem surrounding the island. The day concluded with Ocean Discovery Night – All About Sea Turtles, an educational session designed to deepen understanding of one of the Maldives’ most iconic marine species.
The sustainability programme continues with June Sea Turtle Week, held from 8 to 16 June, featuring immersive experiences that connect guests with marine conservation efforts. Highlights include a Turtle Reef Snorkelling Excursion with the marine biologist on 10 June, offering participants the opportunity to observe sea turtles in their natural habitat while learning about ongoing research and protection initiatives.
The programme will culminate on 16 June, coinciding with World Sea Turtle Day, with an interactive presentation dedicated to sea turtle conservation and the challenges these marine species face in today’s oceans.
“Education and engagement are powerful tools for conservation. Through our partnership with Alila Kothaifaru Maldives, we aim to inspire greater appreciation for the underwater world while encouraging responsible interactions with marine life. Whether planting corals, participating in reef clean-ups, or learning about sea turtles, guests have the opportunity to make a positive impact while experiencing the extraordinary biodiversity of the Maldives,” said Igor Semenov, Dive Centre and Watersports Manager of Euro-Divers at Alila Kothaifaru Maldives.
“Sustainability lies at the heart of the Alila experience. From preserving our island’s natural landscape to protecting the vibrant marine ecosystems that surround us, we are committed to creating meaningful opportunities for our guests to connect with nature and become active participants in conservation. Our World Environment Day and World Ocean Day initiatives reflect our belief that every small action can contribute to a healthier planet for future generations,” said Thomas Weber, General Manager of Alila Kothaifaru Maldives.
Through these initiatives, Alila Kothaifaru Maldives continues to champion responsible tourism and environmental conservation. The resort’s sustainability programme fosters meaningful connections between guests and the natural environment while supporting the protection of the Maldives’ unique ecosystems for generations to come.
The resort continues to share updates on its sustainability initiatives, marine conservation programmes, and immersive guest experiences through its Instagram account as part of its ongoing journey to protect the natural beauty of the Maldives.

Anantara Maldives celebrates 10,000 coral milestone with Dr Oriana Migliaccio
The coral-ringed islands of the Maldives have long been associated with celebration. As Anantara Hotels & Resorts marks 25 years of locally rooted experiences, Dr Oriana Migliaccio, Resident Marine Biologist at Anantara Dhigu Maldives Resort, Anantara Veli Maldives Resort and Naladhu Private Island Maldives, is also marking a milestone of her own by overseeing the planting of the 10,000th baby coral.
With a PhD in Life and Biomolecular Sciences and a lifelong dedication to the sea, Oriana has found herself in the setting she had long hoped her studies would lead to: immersed in nature from sunrise to sunset, and often long after, when she guides guests through the otherworldly beauty of night-time dives. For travellers who arrive in the Maldives seeking luxury, time with Oriana often shifts the focus. Her enthusiasm and sense of purpose draw in guests of all ages, from families to spa devotees, inviting them to discover the living soul of the reef.
Oriana’s journey began in Naples, where beachcombing with her mother and grandmother first sparked her fascination with the ocean. As she listened to stories of a Mediterranean once rich with seahorses and sponges, she became determined to understand the reasons behind their disappearance. Years later, during her Open Water certification in the Red Sea, that early curiosity developed into a clear sense of purpose. Taking her first breath underwater, she descended into a world of coral polyps, weightless among creatures she had previously only read about. When a Napoleon wrasse drifted past, calmly observing her, she knew she had found her calling.
“Pursuing a PhD was never just about academia. It was about gaining the tools to become a voice for the ocean and dedicating my life to protecting what first inspired me as a child.”
For Oriana, becoming a voice for a force as powerful, little understood, and vulnerable to human impact as the ocean begins with education. One of her proudest achievements is the creation of the ‘Reef Hero’ PADI speciality, a course that teaches divers the fundamentals of coral conservation. Under her mentorship, guests often experience a change in perspective, moving from passive observers to active protectors.
“You can literally see the moment when curiosity turns into care. When a guest realises that their actions — how they dive, what they touch — can protect an ecosystem, they stop being just visitors and become guardians.”
Life on pristine islands can shield travellers from the realities of pollution, a contrast that is not always shared by local communities. In her workshops, Oriana helps bridge that gap by showing guests how abandoned ghost nets, among the most recognisable symbols of environmental harm, can be transformed into bracelets. By turning these marine threats into keepsakes, she creates opportunities for conversations about responsibility, renewal, and the impact of individual choices.
Her work is part of a wider network of Anantara sustainability champions whose efforts span the globe. Together, they contribute to Anantara’s HARP initiative, or Holistic Approach to Reef Protection. Since 2017, Oriana has personally overseen the growth of more than 10,000 corals. Guests often check in on their adopted corals through underwater camera streams, but it is the return visits years later that resonate most, when they see their once-small coral saplings transformed into thriving clusters.
Children find this work especially meaningful, as they begin to see themselves as future custodians of the sea. Through Oriana’s ‘Marine Biology for Kids’ sessions, young guests learn to view the water as mother ocean, a living presence that shapes their world and deserves their care. Their questions often stay with her. One child once asked, “If the ocean is alive, can it feel when we hurt it?” For Oriana, such questions show how naturally children combine science with empathy, offering a perspective from which adults can also learn.
“Their curiosity gives me hope, because they see the ocean not as a resource, but as a living entity worth protecting simply because it exists and is alive. That mindset is exactly what the future needs.”
In a nation where rising seas and warming waters remain constant concerns, preserving biodiversity offers a sense of agency. For visitors and local communities alike, taking part in restoration work becomes a way to respond to environmental changes that can otherwise feel overwhelming in scale and speed, grounding their efforts in something hopeful and tangible.
“In the Maldives, sustainability is not optional; it is survival. My vision is to leave behind a lagoon that is healthier, more resilient, and more alive than the one we found.”
