Climate-induced planned relocation is becoming an unavoidable policy issue for some highly exposed communities. Although relocation should remain a last resort after other realistic options for adaptation in place have been assessed, ensuring that the money is available when needed to support relocation is critical. The challenge is that funding is insufficient, drawn from diverse sources and often arrives too late and in fragmented forms: for example, one project for housing, another for infrastructure, and little predictable support for consultation, land negotiations, safeguards, livelihoods, host communities or long-term maintenance. The financing problem is therefore not only the scale of the costs, but the difficulty of organising money over time and across institutions and safeguards. This can leave governments reacting after crises rather than planning before risks become unmanageable.
Sovereign trust funds offer one practical way to address this gap. They do not create finance by themselves, but they can provide a country-owned platform for receiving, sequencing and reporting domestic revenue, bilateral support, multilateral development bank (MDB) finance, climate funds, disaster risk finance, and loss and damage resources. They present an alternative to predominantly loan- and grant-based financing for planned relocation. Fiji’s Climate Relocation of
Communities Trust Fund shows both the promise and limits of this approach: It provides a legal and institutional basis for relocation finance within government and links international funding to procedures, but it still requires capitalisation, administrative capacity and long-term technical support. The model presents an opportunity to support sovereign, rights-based financing systems rather than relying solely on donor-funded, often piecemeal relocation projects. It can also make funding available at the appropriate time and without undue time pressure.
Key policy messages:
• Finance planned relocation before a crisis, especially assessment, consent, land, safeguards and project preparation.
• Treat relocation as a long-term investment in the collective good, rather than solely as a construction or emergency response measure.
• Support sovereign trust funds where they are legally mandated at the national level, budget-linked, transparent and capitalised.
• Use finance to uphold quality and rights, including community-led processes, support for host communities and support for long-term livelihoods.
