Acting on the Climate Crisis: Toward Health System Resilience in the Pacific

Pacific Island Countries and Territories are experiencing intensifying health threats due to climate change, including the rising incidence of vector- and waterborne diseases, worsening non-communicable disease and increasing mental health stress. The vulnerability of health systems is compounded by the high proportion of facilities located near coastlines and the lack of essential infrastructure such as electricity, water, and sanitation services. Climate change also undermines the social determinants of health which impact food security, livelihoods, and access to care, particularly for remote and vulnerable populations. In response, the Pacific has mobilised a strong regional agenda to address the climate-health nexus, supported by high-level commitments such as the Pacific Health Ministers. This paper highlights how countries are advancing climate-resilient health systems through governance, adaptation planning, surveillance, policy alignment, and cross-sectoral coordination. It outlines strategic priorities for sustained action and emphasises the importance of climate financing, leadership, and community engagement. The Pacific’s collective experience offers a compelling model for how regions can respond to climate-driven health risks with unity, innovation, and equity at the core, ensuring that health systems can protect communities now and into the future.
