Financing Climate Resilience in Pacific Island Nations: Fiscal Policy Solutions in the Wake of Shifting ODA and Multilateral Challenges

Abstract

Pacific Small Island Developing States (PSIDS) face escalating climate threats—rising sea levels, intensifying storms, and ecological decline—while a shifting funding landscape undermines their resilience. Official Development Assistance (ODA), a lifeline for PSIDS, is diminishing, with the United States Agency for International Development (USAID) facing severe cuts under the Trump administration’s 2025 foreign aid freeze, slashing over 80% of its programs. This article investigates fiscal policy solutions to bolster climate resilience amid these challenges, focusing on green bonds, debt-for-climate swaps, domestic revenue mobilisation, and blended finance. Drawing on policy analysis and case studies from Fiji (green bonds), the Caribbean (debt swaps), and Micronesia (digital resilience in FSM, sustainable diversification in Palau), it evaluates their efficacy against declining ODA and multilateral hurdles, including geopolitical tensions and inefficiencies in institutions like the Asian Development Bank and Green Climate Fund. Leveraging data from the World Bank, United Nations, and regional frameworks like the Pacific Islands Forum, the study proposes enhanced multilateral cooperation and fiscal innovation to close the funding gap. It concludes with urgent recommendations to ensure PSIDS’ survival and sustainable development in a warming world.
