Tuna Fisheries: A strengthening El Niño is expected to shift tuna grounds and fishing activity across the Pacific through 2026 and into 2027. Niue is also among the islands forecast to face reduced rainfall, adding to climate pressures on local industries. Ocean Investment: Pacific leaders at pre-COP31 called for greater climate finance and regional cooperation to protect ocean ecosystems and economies, including those affected by changing tuna stocks. Food and Health: Niue has one of the Pacific’s highest childhood obesity rates: 38% of children and adolescents aged 5–19 are affected. The findings add pressure on governments to improve food environments and curb the reach of ultra-processed foods and sugary drinks.
