Intl researchers in Maldives develop new way of growing islands, coastlines
Researchers at Massachusetts Institute of Technology (MIT) and in the Maldives have come up with a solution to help coastal communities threatened by climate change: submersible objects carefully placed to promote the growth of beaches and islands.
The Growing Islands project is the work of MIT’s Self-Assembly Lab and Maldivian organisation Invena, who came together to explore how design could stop coastal erosion and sea-level rise — two problems associated with increasing global temperatures.
MIT’s Self-Assembly Lab typically produces objects that build themselves, such as inflatables with multiple final forms. These structures respond differently depending on the amount of air pressure inside, thanks to the intricate geometries 3D printed in their interior.
The Self-Assembly Lab has been eager to see if these computational design approaches could work on a more macro level.
MIT designs self-growing sandbars, islands and beaches
“For a long time I’ve thought, ‘isn’t there a way that we could utilise some of the energy that’s just naturally around us in disasters — you know earthquakes, tornadoes, landslides, tsunamis — and do something productive’,” Self-Assembly Lab head Skylar Tibbits said.
“Couldn’t we use that to design and build rather than destroy?”
From that initial impetus the team came to focus on wave energy. Invited to the Maldives by Invena, they noted that sandbars, shaped by waves, grow rapidly and follow a predictable pattern.
They thought that if they could analyse this pattern and replicate it, they might be able to strategically control the sandbar growth. In effect, they would make self-growing sandbars, islands and beaches.
Tests to continue over coming years
After experimenting with variously shaped submerged objects and wave patterns in a tank in their lab, the group took their work into the field in February, sinking several three-by-three-metre structures off the Maldivian coast.
The structures are large bladders, sewn out of canvas and biodegradable material and filled with sand. The researchers say they are low-cost, easy to deploy, adaptable and work with nature rather than fighting against it.
The group will continue to observe the results and run more field tests over the coming years.
While the title of the project is Growing Islands, the objects actually have three distinct potential uses: the first is to construct all-new islands. The second and third Tibbits says are probably more immediately relevant: supporting existing islands and beaches.
About 40 per cent of the world’s population is thought to live in coastal areas, which are threatened by erosion, rising lea levels and storm activity heightened by climate change.
Growing islands “more elegant solution” to artificial reefs
One of the current antidotes to this is the building of artificial reefs, which works on similar principles as the Growing Islands project but employs less precision and more man-made materials.
Tibbits also says the Self-Assembly Lab’s proposal is many times better than dredging, where sand is dug out from one section of the ocean and moved to another.
This is the current process for building artificial islands, but it is energy intensive, can negatively impact marine ecosystems and requires frequent attention to stop deposits washing away.
“We want to let structures grow and emerge and build themselves by using wave energy or natural materials, found materials and simple forces in the environment,” Tibbits said.
“We think it’s a more elegant solution or a more sustainable approach to building than manmade fixed infrastructure.”
Several artificial island projects are currently in development around the world, including what is set to be one of the world’s largest in Hong Kong and a network of nine joined together into a tech hub outside of Copenhagen.
Architecture firm BIG also recently unveiled a concept for a floating city that could help populations threatened by extreme weather events and rising sea levels.
Nova Maldives will renew its partnership with PADI this September to co-host Project AWARE Week from 16 to 20 September 2026.
Organised by the resort’s marine team, the programme will give guests, from first-time snorkellers to experienced divers, opportunities to combine marine wildlife observation with practical conservation activities. The initiative is intended to turn time spent in the ocean into an educational experience while encouraging greater awareness of marine conservation.
This year’s AWARE Week coincides with PADI’s 60th anniversary and Nova Maldives’ fourth year of operation in South Ari Atoll. Now in its eighth global edition, PADI AWARE Week has developed into a citizen science movement within the diving community and has helped rescue more than 41,000 entangled marine animals to date.
Through its continued participation, Nova Maldives aims to encourage guests to become ocean advocates and remain engaged with marine conservation beyond their stay.
Guests staying at Nova during AWARE Week will be able to participate in a programme designed for different levels of ocean experience. Activities will include:
- Ocean immersion and storytelling: Sessions inspired by Blue Planet and other ocean documentaries, highlighting the diversity and vulnerability of marine life.
- Dive Against Debris: Underwater clean-up dives in the resort’s lagoon, during which participants will remove plastic and other waste before recording the findings in PADI AWARE’s global database.
- Whale shark snorkelling: Guided encounters that will allow guests to swim alongside whale sharks in the open waters of South Ari Atoll.
- Manta ray and turtle-spotting excursions: Guided boat trips to feeding and nesting areas where manta rays and turtles can be observed in their natural habitats.
- Coral restoration workshops: Practical sessions introducing guests to coral planting and the resort’s ongoing reef regeneration work.
“Some of the most meaningful work happens when you show up year after year. Four years into Nova’s story, we’ve learned that the health of the reef tells us a great deal about the impact we’re making, and that the guests who choose to return aren’t just here for the view,” said Abdulla Aboobakuru, General Manager of Nova Maldives.
“They’re here because Nova reflects something they already care about, including care for the ocean, a sense of community and a more thoughtful way of experiencing the places we visit. That’s what we hope Nova can inspire in new and returning guests alike: less a destination, more a calling.”
The resort’s marine conservation work continues throughout the year. Its coral nursery contains a growing collection of metal frames holding individually secured coral fragments, which are later transplanted onto the house reef. Guests are regularly invited to participate in the planting process, while the marine team monitors the young coral colonies as they develop.
Nova Maldives also maintains partnerships with the Maldives Whale Shark Research Programme and Manta Trust. The resort is accredited as a Responsible Manta Tourism Operator, with the partnerships supporting its year-round approach to marine conservation.
Renowned for its marine life and underwater experiences, Sun Siyam Vilu Reef, part of Sun Siyam’s Privé Collection, has been named Best House Reef at the Travel Trade Maldives (TTM) Awards 2026.
The award recognises the resort’s marine environment, which is accessible directly from its beaches and overwater villas. The annual TTM Awards and Gala brings together travel professionals and hoteliers from across the archipelago to recognise achievements within the Maldivian hospitality industry.
The island’s coral reef is home to marine species including resident sea turtles, reef sharks, tropical fish and eagle rays. Guests can explore the reef through guided excursions led by the resort’s resident marine experts, customised scuba-diving experiences and coral restoration initiatives designed to support the long-term preservation of the marine environment.
“Our reef is the living soul of Sun Siyam Vilu Reef, shaping every visitor’s journey from the moment they step into our turquoise lagoon,” said Masdhooq Saeed, Cluster General Manager. “To be named the Maldives’ Best House Reef is an immense honour, strengthening our commitment to nurturing this remarkable marine sanctuary so our guests can keep discovering its quiet magic beneath the surface.”
Travellers seeking underwater experiences can book directly with the resort to access exclusive benefits and guided marine excursions.
Sun Siyam Vilu Reef, part of the Privé Collection within the House of Siyam, has announced its festive programme, “Eutopia: The Infinite Bloom”, which will run from 22 December 2026 to 7 January 2027.
The seasonal programme features activities and experiences for guests of all ages. Dining will take centre stage with Christmas Eve and New Year’s Eve gala dinners by the water, exclusive Chef’s Table experiences and seafood barbecues on the beach.
The evening entertainment programme will include live acoustic performances, island DJ sets, aerial dance shows and Maldivian cultural performances.
During the day, guests will be able to explore the resort’s lagoon through activities such as house reef snorkelling, sunset Jet Car rides and sandbank excursions. The Spa will offer wellness rituals and couples’ therapies, while younger guests can take part in gingerbread decorating, a fashion show and Santa’s arrival on the beach.
“Eutopia is our invitation to celebrate and embrace nature, meaningful moments, and the relaxed luxury that defines Sun Siyam Vilu Reef through our festivities,” said Masdhooq Saeed, Cluster General Manager.
“From unforgettable ocean adventures to starlit beach celebrations, every experience has been thoughtfully designed to create lasting memories that will continue to flourish long after the season ends.”
The programme will culminate with a New Year’s Eve celebration on the beach on 31 December, featuring live music, midnight toasts and a fireworks display over the water.
The resort’s festive programme is available to view online, with bookings open for stays between 22 December 2026 and 7 January 2027.
