Climate change in the Pacific is threatening the health of Pacific islanders, as well as economic and social development. Extreme weather events, especially cyclones, floods and droughts, are displacing populations, causing injuries and psychological trauma, and are increasing the risks of infection and malnutrition. Hotter and wetter climates are increasing the risks for vector-borne disease. Disasters related to climate change are disrupting the delivery of health-care services and are increasing the risks of disease and death among vulnerable groups, especially young children, women of reproductive age, older people and people with disabilities. This report informs and encourages timely action by Member States towards building resilience of health sector to climate change. It targets policy-makers and advisers in various sectors, public health practitioners, scientists and community stakeholders.
