Nauru Sets Out Climate Adaptation Priorities to 2035

The Scale of the Problem

Climate change is not a distant threat for Nauru — it is an immediate and accelerating reality. The island's maximum elevation is just 65 metres, and the majority of the population and critical infrastructure sits along a narrow coastal belt.

Rising sea levels, intensified storm surges, and coastal erosion threaten roads, homes, the airport, and government infrastructure that sits within metres of the shoreline. For a nation of roughly 21 square kilometres, there is very little inland space to retreat to.

The CARE4N Coastal Resilience Project

Nauru's most concrete coastal protection effort is the Coastal Area Resilience Enhancement for Nauru project — CARE4N — supported through the Global Environment Facility (GEF) with the Asian Development Bank as implementing agency.

The project's objective is that Nauru's coastal assets and ecosystems enjoy improved protection in an integrated, affordable, sustainable, adaptive, equitable, and replicable manner. Funding comprises a GEF allocation of USD 2,660,600 together with USD 1,000,000 in co-financing.

Importantly, Nauru's own climate documentation acknowledges that CARE4N will not cover the full cost of implementing all recommended hard and nature-based solutions — meaning the project is a starting point rather than a complete coastal defence programme.

Updated Nationally Determined Contribution (2025-2035)

Nauru has submitted an updated Nationally Determined Contribution (NDC) covering 2025 to 2035 under the Paris Agreement. The document sets out the country's adaptation and mitigation priorities for the coming decade and is published in full on the UNFCCC website.

The NDC is the authoritative statement of what Nauru itself commits to and requests. It is a more reliable basis for understanding national climate policy than secondary reporting, because it is the document Nauru formally submits to the international process.

Adaptation Approaches Under Discussion

Alongside engineered coastal protection, Nauru's adaptation planning has included discussion of managed relocation of people and assets toward the island's higher interior (the Topside phosphate plateau) — an approach that reflects the reality that in some locations, defending the coastline may not be feasible indefinitely.

Other measures under consideration across Pacific island states include natural coastal buffers such as native vegetation and coral rubble berms, and early-warning systems for storm surges and king tides. Nauru's specific mix of measures is set out in its NDC and project documentation.

What This Means for Visitors

For visitors, climate adaptation work has practical implications:

• Coastal construction and protection works can cause localised access restrictions and minor traffic disruption — ask at your accommodation about current conditions
• Some beach access points may be affected by works; conditions change, so check locally rather than relying on older guides
• The Topside plateau offers the island's most dramatic landscapes and is worth visiting for its own sake

Nauru remains a destination where conditions are best confirmed locally on arrival. Treat any travel guide — including this one — as a starting point, not a substitute for current local information.
