In 2025, greater than 90 per cent of Tuvaluans utilized for a visa scheme to get hold of residency or citizenship in Australia. Simply earlier than that, in 2022, the Authorities of Tuvalu created the primary ‘digital nation’ within the metaverse to protect its statehood and tradition if its bodily territory disappears.
In these small, remoted island communities, many with solely a few thousand residents, there are scarce sources obtainable to fight the existential risk that rising sea ranges pose. Left alone, there’s little or no they’ll do.

“Quite a lot of occasions individuals say, ‘you’re simply speaking about a thousand individuals, you’re speaking about six thousand individuals’. However for us, these 6,000 persons are on the frontline of this local weather disaster, and we owe every little thing to them to safeguard their livelihoods and never disturb their day by day lives,” a senior official at UN Improvement Programme (UNDP) within the Pacific, Tuya Altangerel, informed UN Information.
The Authorities, with assist from the UNDP, is stepping up efforts to save Tuvalu by defending the nation’s most populated islands.
Small will increase, devastating penalties
Sea degree rise is primarily pushed by international warming which causes water to broaden because it heats up and accelerates the melting of land-based ice sheets and glaciers.

Few locations are experiencing it as quickly because the Pacific Ocean the place components akin to ocean currents and winds mix with international warming to create a ‘pile-up’ impact on a number of the most weak low-lying islands.
Within the impartial island nation of Tuvalu, the extent has risen 21 centimetres in 30 years, almost twice the worldwide common. On the present price, some projections recommend 95 per cent of the nation might be underneath water by 2100.
Why excessive tides are the actual hazard
The best day-to-day problem for island communities is the rise within the quantity and depth of excessive tides.
“Our islands are drowning,” Ms. Altangerel stated.
With the nation averaging underneath two metres above sea degree, conventional strategies in coastal safety – whether or not constructing sea partitions or nature-based strategies akin to planting mangroves – “not work” in managing these tides, she stated.
“If we plant mangroves, the mangroves shall be merely swallowed by the ocean… The king tide will simply wash over the mangroves, or they’ll wash over the seawalls,” she stated.
It’s not nearly coastal areas disappearing, it’s additionally the individuals’s sense of nationhood and likewise the longer term existence of those nations are very a lot underneath risk

Migration, a answer?
While adaptation tasks are underway, migration can also be an possibility. In 2023, the Tuvaluan and Australian Governments launched the Falepili Union, a treaty permitting 280 Tuvaluans to relocate to Australia every year for residency or citizenship.
Final yr, 90 per cent of the nation’s inhabitants utilized for the primary spherical of the visa poll.
Different agreements are in place in Kiribati and Vanuatu which permit working residents to get hold of visas in Australia. In the meantime, New Zealand presents 75 residency visas per yr to Kiribati and Vanuatu, and the USA has an settlement with the Marshall Islands the place residents can reside, work and research within the US with out a visa.
Towards this backdrop, there are considerations over the implications for the tradition and heritage of Pacific peoples, particularly these in conventional livelihoods, if populations transfer away en masse.
Can a nation survive with out land?
With rising sea ranges, it’s potential that some island nations might bodily disappear.
“It’s not nearly coastal areas disappearing, it’s additionally the individuals’s sense of nationhood and likewise the longer term existence of those nations are very a lot underneath risk,” Ms. Altangerel stated.

An Worldwide Court docket of Justice ruling in 2025 clarified that lack of its bodily territory due to sea-level rise does not mechanically consequence within the lack of its statehood or sovereignty, permitting Tuvalu to stay a nation state with rights over its ocean sources and a seat on the UN, even when its islands are underwater.
A template in Tuvalu
In Tuvalu, UNDP – working alongside the Authorities and the Inexperienced Local weather Fund – began a novel adaptation plan again in 2017 primarily based on detailed sensor mapping to create over seven hectares of latest land designed to keep above projected sea ranges past 2100.
The Tuvalu Coastal Adaptation Mission dredges sand to create elevated land that’s protected in opposition to storm surges within the islands of Funafuti, Nanumea, and Nanumaga.

“These are very drastic measures,” warns Ms Altangerel with the venture costing shut to $55 million up to now: “We principally rebuild the land across the atolls so that there’s protected land the place individuals can construct shelters, housing.”
Part two began in 2024 the place a additional eight hectares shall be added alongside the southern shoreline of the nation’s capital, Funafuti, on the island of Fongafale the place 60 per cent of the nation’s inhabitants reside. Many Tuvaluans from much less protected atolls have already migrated there searching for safety.
One other means the Authorities and the UNDP is supporting Tuvaluans to stay, is thru offering an insurance coverage scheme when flooding happens from excessive tides, and an preliminary 400 households in Funafuti will obtain automated funds of up to $1,500 per excessive tide occasion.
For Tuvalu, Kiribati and the Marshall Islands – three of the 4 lowest mendacity nations on the planet – the measures in Tuvalu might supply a template for his or her future adaptation and their survival.
“If we handle to safeguard Tuvalu as a nation…we’re contributing all of this wonderful work to be scaled up and replicated throughout the Pacific, but additionally throughout different small island growing States,” Ms. Altangerel stated.
Saving the Pacific
Visiting the Pacific islands, that stretch hundreds of miles aside on the planet’s largest ocean seven years in the past, UN Secretary-Normal Antonio Guterres stated, “if we save the Pacific, we save the world.”
Because the world marks Earth Day on 22 April, in Tuvalu, the trouble just isn’t solely about adaptation, however survival and the query of whether or not a nation can maintain onto its land, id and future because the seas rise.
