The Pacific island nation of Tuvalu is set to become the first modern country to disappear due to climate change, as rising sea levels threaten to render the archipelago uninhabitable by 2060. Located halfway between Hawaii and Australia, Tuvalu, with its 11,000 residents, finds itself at the heart of an unprecedented legal and humanitarian crisis: can a nation exist without physical territory?
According to the Intergovernmental Panel on Climate Change (IPCC), Tuvalu is among the countries most at risk from rising oceans, a direct consequence of global warming. In response, the Tuvaluan government is working to delay the inevitable and secure the future of its people and national identity.
Tuvalu Fights for Sovereignty Without Land
Tuvalu has already signed a climate refugee agreement with Australia, ensuring relocation options for its population. Yet many islanders hope to remain on their ancestral land for as long as possible. At the same time, Tuvalu is lobbying international organizations to preserve its status as a sovereign state, even in the event of total territorial loss.
The challenge is unprecedented. The Montevideo Convention of 1933 defines a state as requiring a defined territory, a permanent population, a government, and the ability to engage with other states. However, the Tuvaluan government argues that these criteria must evolve to reflect the realities of the climate crisis.
Neighboring low-lying nations such as Nauru, Kiribati, and the Marshall Islands face similar threats. In a historic move, Tuvalu amended its Constitution in September 2023, stating that “the State of Tuvalu, in its historical, cultural, and legal framework, shall continue to exist in perpetuity, regardless of the impacts of climate change or other causes leading to the loss of Tuvalu’s physical territory.”
The First Digital Nation in the Making
Protecting Tuvalu’s maritime sovereignty is central to its survival. Its exclusive economic zone spans 900,000 km², with commercial fishing forming the backbone of its economy.
“We are raising a legal question the world has never faced: can a country exist without physical territory?” explains Tuvalu’s Minister for Transport, Energy, Communications, and Innovation, Simon Kofe.
To safeguard its identity, Tuvalu has launched the Future Now initiative. This ambitious project aims to digitally preserve the nation’s geographical, historical, and cultural heritage. In time, all democratic functions birth registration, elections, and more would be managed through this digital platform, effectively making Tuvalu the world’s first digital nation.
Such a future would require formal agreements with host countries for Tuvaluan climate refugees, with Australia already expressing willingness to assist.
A Legal and Diplomatic Battle Ahead
Tuvalu’s new Prime Minister, Feleti Teo, elected in January 2024, is advocating for the international community to recognize Tuvalu’s statehood beyond its physical existence. At the United Nations General Assembly in September 2024, he urged world leaders to support this effort.
“A principle that I strongly uphold is state continuity. No matter what happens with the rising seas, Tuvalu’s status as a recognized state must be preserved,” he declared.
The Pacific Islands Forum, comprising 18 members including Australia and New Zealand, backed this demand with a formal declaration in 2023.
Nevertheless, significant legal uncertainties remain. According to Jean-Baptiste Dudant, an international law expert at the University of Versailles, “The implications of a de-territorialized state are still unclear. The real challenge is ensuring concrete legal recognition. On what firm legal basis could state continuity rest, and how can it be practically guaranteed?”
As Tuvalu’s land faces submersion, the world must grapple with a profound question: can nations survive when their territory disappears beneath the waves?
