Advanced technologies, adaptation plans and strategic alliances to save the nine sovereign atolls in the Pacific from physical and cultural disappearance

In the heart of the Pacific Ocean, an island nation of nine atolls is on the front lines of the fight against rising sea levels caused by global warming. With a population of around 12.000, Tuvalu faces an existential threat: half of the capital island, Fongafale, could be submerged by tides by 2050. Without significant intervention, 95 percent of the territory could be inundated by 2100 as soon as possible.

To address this crisis, Tuvalu launched the Tuvalu Coastal Adaptation Project (TCAP) in 2017, with support from the Green Climate Fund and the United Nations Development Programme (UNDP). The project aims to reduce exposure to coastal hazards through the construction of resilient infrastructure, such as the creation of 7,3 hectares of raised land designed to remain above sea level until the end of the XNUMXst century.

Tuvalu has also used some of the revenue from the “.tv” Web domain, used by many television stations around the world, to fund initiatives related to the fight against climate change. The “.tv” Web suffix, assigned to Tuvalu in 1996 by the Internet Corporation for Assigned Names and Numbers, has become a significant source of revenue for the country due to its association with the concept of television and its popularity among streaming platforms such as Twitch.tv.

Annual revenues from licensing the “.tv” URL domain amount to approximately AUD$5-7 million, representing a substantial portion of Tuvalu’s national budget, much of which is absorbed by the fight against global warming.

L-TAP: Here is the plan for the future of the Nation

In parallel to the TCAP, the Government of Tuvalu, again in collaboration with UNDP, has developed the Long-Term Adaptation Plan (L-TAP), also known as “Te Lafiga o Tuvalu” (locally “Tuvalu’s Refuge”). This plan envisages the creation of 3,6 square kilometres of safe, elevated land, intended to progressively accommodate the country’s population and infrastructure, ensuring food, energy and water security, as well as the functioning of government and health activities.

The L-TAP represents a breakthrough in climate adaptation, being the first technically feasible national plan based on science and consistent with projections of ocean level rise, especially in the vast Pacific that envelops the country. However, its implementation requires concerted efforts to unlock private capital flows and address macroeconomic factors that hinder economic growth.

A technology at the service of survival

To better understand the impact of rising seas, Tuvalu has used Light Detection and Ranging (LiDAR) technology to precisely map the height of the land surface and the depth of the seabed across all of its nine atolls, covering approximately 500 square kilometres. This data has informed flood forecasting models and supports coastal monitoring, providing a solid basis for adaptation strategies.

Additionally, the Government of Funafuti has partnered with the US company Atmo to improve weather forecasting through the use of artificial intelligence. This partnership aims to provide high-resolution forecasts up to ten days, improving the country's preparedness for extreme weather events.

How to Preserve Cultural Identity in the Metaverse

In addition to physical measurements, Tuvalu is exploring digital solutions to preserve its cultural identity. The Government has begun the creation of a “digital twin” of the country, a virtual replica that preserves data, images and 3D models of the islands. This project, developed in collaboration with the organization PLACE, aims to keep Tuvalu's culture and history alive even in the event of the physical loss of the territory.

However, the idea of ​​a “Digital Nation,” as envisioned by the “Future Now Project,” has sparked heated debate. Former Prime Minister Enele Sopoaga has criticized the concept, saying there is no international legal basis for a state to disappear due to rising sea levels and that Tuvalu should not be considered destined to disappear, having to retreat “to the cloud,” as envisioned by Simone Kofe’s Cabinet and her heartfelt and dramatic appeal to the world.

Known as the British Colony of the Gilbert and Ellice Islands until 31 December 1975 and nicknamed in the United Kingdom “the Cinderella of the Empire” at least until the beginning of the Second Post-Guetta, Tuvalu is also a very new nation.

From international collaborations to future challenges

Tuvalu's fight against climate change has attracted international attention and support. Australia e New Zealand They funded a second phase of the TCAP (TCAP-II), which includes the protection of 800 metres of vulnerable coastline and the creation of approximately eight hectares of new raised land.

Additionally, in November 2023, Tuvalu and Australia signed the Falepili Union Treaty, which provides citizens of the former country the ability to migrate to the latter’s territory in response to climate change. The treaty also provides significant financial support for adaptation projects and disaster relief.

Despite these efforts, the challenges remain immense. According to World Bank estimates, adaptation costs for Tuvalu could reach $2100 billion for a half-meter sea level rise by 20, an amount equivalent to about XNUMX years of the country's Gross Domestic Product.

An example for the world of will and proactivity

Tuvalu is an example of resilience and innovation in the face of an unprecedented climate crisis. Through the adoption of advanced technologies, long-term adaptation plans and the preservation of its cultural identity, the Pacific nation demonstrates that it is possible to address the challenges of climate change with determination and creativity.

As Dr Arthur Webb, Coastal Adaptation Specialist with TCAP, the Tuvalu Coastal Adaptation Project, said:

“Tuvalu is charting a path that other vulnerable countries can follow. The combination of science, technology and political will is key to building a sustainable future.”

The international community has a duty to support the Government of Funafuti and other countries in similar conditions, not only for moral reasons, but also because the solutions developed here could be crucial to addressing global climate challenges.
