COP28 PRISMSS Side Event -Restoring Island Resilience

Résumé

The Pacific Island nations of Niue and Tonga are leading global efforts to expand the management of invasive species at a large-landscape scale and increase the resilience of their ecosystems and communities to the impacts of climate change. Niue’s Environment Minister, Hon. Mona Ainuu, recently made an ambitious pledge for the country to control four priority invasive species by 2030, including Taro Vine, rats, feral pigs, and the coral eating Drupella snail. This work will help to enhance Niue’s premium ecotourism brand and directly support the provision of green jobs. Tonga has also pledged to expand the management of priority invasive species at a large-landscape scale following the successful eradication of rats from Late Island, the largest eradication ever undertaken in the Pacific Islands region. Studies have shown that, once rats are removed, the nutrients from returning seabird populations restore the climate resilience of coral reefs and increase the productivity of fish stocks by up to 50%. Tonga’s plans to scale-up the management of priority invasive species will help expand its national park system, provide refugia for 95% of the country’s biodiversity, and directly increase the climate resilience of its ecosystems and communities.
