In the Pacific Island region, oceanic fisheries target four species of tuna – skipjack, yellowfin, bigeye and South Pacific albacore – and make critical contributions to economic development, government revenue and livelihoods in most nations. Climate change is expected to have profound effects on oceanic fish habitats, food webs, the fish stocks they support and, as a consequence, the productivity of fisheries.

In the Pacific Islands region, fish and invertebrates (specifically shellfish) fulfil important ecological roles in coastal and oceanic habitats, and many species are targeted by fisheries, making vital contributions to food security, livelihoods, government revenue and cultural heritage.

The climate is changing and this poses significant threats to human health. Climate change is one of the greatest challenges facing Pacific Island countries and territories due to their unique geophysical features, and their social, economic and cultural characteristics. The Pacific region also faces challenges with widely dispersed populations, limited resources and fragmented health systems. Over the past few years, there has been a substantial increase in international aid for health activities aimed at adapting to the threats of climate change. This funding needs to be used strategically to ensure an effective approach to reducing the health risk from climate change. Respecting the principles of development effectiveness will result in more effective and sustainable adaptation, in particular, 1) processes should be owned and driven by local communities, 2) investments should be aligned with existing national priorities and policies, and 3) existing systems must not be ignored, but rather expanded upon and reinforced.
