While many island urban settlements are growing rapidly, climate change and increasingly frequent disasters are stressing urban systems. ICLEI promotes sustainable island and urban development through resilience and systems planning, clean energy, coastal fisheries management, infrastructure, innovative finance, ecosystems services, post disaster recovery and sustainable tourism. ICLEI collaborates with Mayors and leaders, through twinning of island cities with other cities and regions, to create fruitful partnerships to deliver scalable solutions to build resilience on islands and globally. Due to the difficulty in obtaining funding in 2017-2018, the initiative was paused and has now been re-activated as of April 2024.
