State Adaptation Report 2021/4 Nature-Based Resilience and Adaptation to Climate Change in Hawaiʻi: A Climate Ready Hawaiʻi Working Paper (2021) While Climate Ready Hawai‘i initially focused on sea level rise (SLR) impacts, it became clear that this document must tackle mauka-makai (coastal and landward) issues, and so, go beyond vulnerability to infrastructure to fully address climate change impacts in Hawai‘i. This Working Paper highlights actions in Hawai‘i that rely on nature-based “green-blue” strategies to adapt to and mitigate climate change. It identifies ongoing efforts in the state, and key action areas for next steps that enhance climate readiness. We hope this document will be used by decision makers, planners, communities, businesses, and scientists as a guide for climate change resiliency work in Hawai‘i.
