Is the Maldives Sinking? What Happens If the Islands Submerge?

September 15, 2025

The Maldives, famed for its turquoise waters and coral-ringed islands, is also the world’s lowest-lying nation—and one of the most threatened by climate change. With an average elevation of just 1.5 metres above sea level, even modest rises pose catastrophic risks. Scientists warn that by mid-century, most of its islands could become uninhabitable, raising urgent questions about survival, sovereignty, and identity. If the land disappears, can the Maldives continue to exist as a nation—or only as a memory?

A Nation at the Water’s Edge

The Maldives is the lowest-lying country on Earth, with an average elevation of just 1.5 m above sea level and its highest natural point barely touching 2.4 m. This unique geography, while making the country a tourist paradise, places it directly on the frontline of the climate crisis.

The Intergovernmental Panel on Climate Change (IPCC) projects global sea levels could rise by up to 1 m by the end of the century. For the Maldives, this spells disaster. Studies suggest nearly 80% of its land may become uninhabitable by 2050. The immediate threats are not just inundation, but loss of freshwater aquifers, relentless coastal erosion, and increasingly frequent flooding that could render communities unsustainable.

What Happens to a Nation Without Land?

International law defines a state by its territory, population, government, and ability to interact with other states. But what if territory disappears beneath the ocean? Legal scholars argue that statehood is not purely physical—it is a legal construct. In theory, the Maldives could continue to exist as a deterritorialized state if its government and people remain intact.

The challenge, however, lies in sovereignty and maritime rights. If islands vanish, so do their baselines, threatening exclusive economic zones and access to marine resources. Some Pacific nations have already called on the UN to protect the sovereignty of sinking states. For the Maldives, this debate is no longer hypothetical but a looming reality.

How the Maldives Is Fighting Back

Despite the grim outlook, the Maldives is actively experimenting with solutions:

• Reclaiming land: Hulhumalé, an artificial island built higher than natural atolls, now houses thousands and serves as a “City of Hope.”
• Floating cities: Blueprints are underway for floating neighborhoods that rise with the sea, reinforced by coral-supporting structures.
• Coastal protection: Breakwaters, sandbags, and groynes line many shores, while reef conservation efforts aim to preserve natural defenses that absorb wave energy.
• Water resilience: With freshwater sources under threat from saltwater intrusion, conservation and desalination projects are being expanded.
  These measures are ambitious but expensive. Estimates suggest the Maldives could require $8–9 billion to build long-term resilience—an impossible figure for a nation contributing less than 0.004% of global greenhouse gas emissions.

The Global Stakes

If the Maldives sinks, it won’t only lose homes and beaches—it risks erasing an entire culture and national identity. Thousands of Maldivians could become climate refugees, forced to migrate while trying to preserve their heritage.

The crisis also underscores global inequity. Wealthy, high-emission nations continue to delay aggressive climate action, while small island states like the Maldives pay the highest price. Maldivian leaders have repeatedly urged the international community to operationalize climate finance mechanisms such as the Loss and Damage Fund, arguing that survival should not come at the cost of crushing debt.

Ultimately, the question of whether the Maldives will “cease to exist” is as much political as environmental. Legally, the country may endure even without land, but the survival of its people, culture, and sovereignty depends on urgent global action. For now, the Maldives remains afloat—but the tide is rising fast.
