The International Organization for Migration (IOM) plans to provide regional support for policies, preparedness, and where applicable, planned relocations in nine South Pacific countries, including Fiji and Vanuatu. These two archipelagos are among the first nations to adopt public frameworks integrating planned relocation. Climate adaptation proves to be here not only technical but also existential, touching on the identity, land, and social structures of the affected communities.

The Essentials

  • Small island states of the Pacific record the highest rate of climate-driven displacement in the world relative to their population, according to the IOM.
  • The IOM plan covers nine South Pacific countries and provides for regional support for planned relocations. The IOM plan presents a funding need of 9.2 million dollars.
  • Sustainable relocation imposes three underestimated burdens: the maintenance of community identity, social reconstruction, and dependence on external financiers.
  • Current relocation models raise unresolved questions about the preservation of long-term community autonomy.
  • The financing of resettlement, its conditions, and the criteria for deciding what will be preserved remain open issues for the coming decade.

Leaving Rather Than Defending: A Choice That Physics Imposes

There is simple logic behind the IOM plan. A dike against rising waters protects a territory until the next cyclone, then it fails or becomes insufficient, and the cost of reconstruction exceeds that of an orderly relocation. Small Pacific islands understood this before large continental nations because they lack the luxury of spreading the problem across space. When the sea rises by a few dozen centimeters, a low atoll can lose its arable land, freshwater reserves, and beaches in a generation.

The IOM 2026-2028 action plan for the South Pacific is based on this reality. It aims to organize planned, preventive, and dignified displacements, rather than hurried flights after catastrophe. Fiji and Vanuatu are hosting IOM pilots linked to recovery and adaptation, as part of a regional plan covering nine countries. They offer two cases with different profiles: two archipelagos with unequal levels of development and communities exposed to distinct coastal risks.

The distinction between forced displacement and planned relocation is not merely semantic. A village that leaves after a cyclone loses its archives, its social bonds, its accumulated knowledge of a territory. A village that plans its departure over three years can carry its community structures, negotiate the host site, organize the transfer of land rights. The difference between these two trajectories entirely determines the quality of life upon arrival.

The Concrete Meaning of “Planned” in Fiji and Vanuatu

In Fiji, community relocations have been underway for several years, with documented and contrasting results. The village of Vunidogoloa, relocated in 2014, is often cited as a precursor case: the community was relocated inland, with new houses financed by the state. Official sources consulted document measures to support livelihoods after relocation. The relocation required reconstruction and diversification of livelihoods, notably through fish ponds, livestock raising, copra drying, and pineapple cultivation, rather than any documented disappearance of economic fabric.

The IOM 2026-2028 plan integrates strengthened community consultation processes, explicit attention to land rights at host sites, as well as cultural and spiritual dimensions in planning. These clarifications matter because in the Pacific, land is a belonging, an ancestor, and a cosmology, not an abstract economic resource.

In Vanuatu, the context is different. The archipelago has more than 80 inhabited islands, several of which are highly exposed to cyclones and coastal erosion. The country is regularly ranked among the most vulnerable in the world to natural disasters. Internal relocation, from one island to another or to the highlands of the same island, is technically more complex because available host sites are themselves constrained by volcanic topography and community land pressure.

Australia is the main funder of the Pacific region on climate issues. The 2026 DFAT documents consulted broadly support climate resilience and response to shocks, particularly through strengthening the adaptive capacities of communities. This is a doctrinal shift: moving from emergency relief to investment in prevention.

The Invisible Cost of Sustainable Resettlement

The figures for abandoned infrastructure are relatively easy to calculate: a well, houses, a school, a jetty. The cost of their replacement at a new site as well. But this calculation does not capture the essential.

Sustainable resettlement, the kind that does not produce an impoverished and uprooted community in ten years, requires several investments that standard accounts ignore. First, it is necessary to rebuild reciprocity networks: who helps whom to build, who shares what in times of scarcity, how are marriages, mourning, and celebrations organized. These networks do not move automatically. They reconstitute or die at the new site depending on whether social conditions permit or forbid them.

Second, land rights must be settled. In many Pacific contexts, customary and collective land regimes play a determining role, but they vary according to states and territories. A displacement involves negotiating with the customary owners of the host site sustainable use rights for newcomers. These negotiations can last for years and fail. If negotiations fail, the displaced risk ending up on land without established legal security.

Finally, services must be maintained. The school, the clinic, the connection to the market. These elements depend on a critical mass of population: below a certain threshold, they are not economically viable. A village of 200 people can relocate without losing this critical mass. A hamlet of 30 people cannot.

The IOM notes that the costs of sustainable resettlement involve social and institutional dimensions whose evaluation remains complex. This is an important acknowledgment and a warning signal for donors. Financing only the physical displacement risks compromising sustainable solutions if social ties, services, and livelihoods are not rebuilt, creating concentrations of uprooted people without a viable economy.

Dependence on Financiers as a Systemic Risk

The IOM 2026-2028 plan relies on external funding. This is inevitable: small island states do not have the resources to finance large-scale relocations themselves. But this dependence creates a structural vulnerability that goes beyond the climate issue.

The priorities of donors evolve, and the political cycles of Australia, New Zealand, or major international climate funds do not always align with the time horizons necessary for successful relocation. Organizing a displacement, consolidating the host site, and rebuilding the local economy require substantial multi-year commitment, significantly exceeding the duration of a three-year project cycle. At the end of the action plan, unconsolidated gains remain exposed to funding interruptions.

The issue of nationally determined contributions (NDCs) to climate action is central here. Several small island states have included relocations in their national climate strategies, seeking to articulate their international climate commitments with their funding needs through multilateral climate finance mechanisms.

The question of who decides is as important as the question of who pays. External funding of relocations influences the technical, land, and institutional parameters of their implementation. Communities risk being integrated into programs whose essential parameters have not benefited from their genuine participation. The IOM 2026-2028 plan seeks to counterbalance this dynamic through participatory processes, but the balance between community governance and donor requirements remains precarious.

The Stockholm Environment Institute (SEI) raises a similar point in its work on ocean sustainability: international financing mechanisms are often designed for measurable one-off projects, not for long social transformations. Adapting these mechanisms to the reality of climate relocations is an institutional project that the international community has not yet seriously undertaken.

Between 2030 and 2040, Two Trajectories for the Pacific Islands

The IOM plan covers 2026-2028. But the relocations that begin now will produce their lasting effects in the 2030-2040 decade. Two major trajectories are emerging, and the choices made today will direct toward one or the other.

In a first trajectory, the relocations of 2026-2030 serve as a learning ground. The mistakes of Vunidogoloa are documented, analyzed, and avoided at subsequent sites. Land governance models adapted to the Pacific island context emerge and are adopted by states in the region. Climate NDCs create more stable multi-year funding, less dependent on bilateral political cycles. Relocated communities build new economies, articulated to the sea but without the vulnerability of the coastal strip, and some become references for other small island states in comparable situations, from Bangladesh to the Caribbean.

In a second trajectory, tensions between donors and communities accumulate. Participatory processes remain formal, host sites are chosen for their cost rather than their cultural relevance, and land rights remain contentious. Displaced communities enter chronic dependence on aid. Lacking viable economic models at new sites, young people leave for capitals, regional cities, Australia, and New Zealand. Relocated villages age and empty out.

Physical relocation succeeds; human relocation fails.

What will distinguish these two trajectories comes down to a few things, but precise things. The duration of financial commitments: ten-year funding is qualitatively different from three-year funding. The quality of consultation: formal or real, with or without community decision-making power over essential parameters. And the preparation of host sites before displacement, not after.

A few signals will allow reading the direction taken by 2028: the proportion of relocations that give rise to land conflicts at host sites, the demographic dynamics of displaced villages in the five years following displacement, and the existence or absence of published independent evaluations on the first cases. If these evaluations exist and circulate, collective learning is possible. If they remain confidential or do not occur, the same mistakes will be repeated from island to island.

The Lessons from the Pacific Islands for the Rest of the World

The dynamics observed in the Pacific offer pertinent lessons for other regions exposed to comparable coastal climate risks, such as Bangladesh, the Nile delta, Mozambique, or Vietnam. Continental states still have room to defend their dikes, their coastal plains, and their port cities. Pacific island states are experimenting with both in-place adaptation, preventing displacement, and where necessary, planned relocation as a last resort solution, offering a direct reference for territories in comparable situations.

The lessons from this involuntary laboratory deserve to be documented with rigor, not only in institutional reports, but in forms accessible to the communities themselves. Fiji has begun to do so with its national relocation policy. Vanuatu is gradually building its framework. These are living policy documents, imperfect, under review. Fiji has a national planned relocation framework, while Vanuatu is progressively developing its instruments relating to resettlement and internal displacement.

The stakes raised by these relocations go beyond technical and financial dimensions. A community that loses its island sees its identity threatened, and the links between territorial belonging and collective identity, being Fijian without Fiji or Vanuatuan without one’s island of origin, remain without established answers. The answers that relocated communities will construct over the coming decade will directly interest other peoples called to make comparable choices.
