A climate adaptation strategy for Mai Po Inner Deep Bay Ramsar site: Steppingstone to climate proofing the East Asian-Australasian Flyway

wintering sites along the EAAF—and other bird migration flyways—to develop landscape- scale climate adaptation strategies. Such plans will enable the migrations to persist, but also ease the vulnerabilities of people and economies concentrated in coastal regions. However, this should happen now, before available options become lost to the rapid and extensive con- version of wetlands from anthropogenic drivers and SLR from the landward and seaward sides, respectively. Acknowledgments We thank the Peter Cornthwaite, CEO WWF Hong Kong and David Olson, Conservation Director for encouraging this study, Chi-Yeung Choi and a second anonymous reviewer for constructive comments. We also thank the Mai Po management team and management com- mittee for their support. Author Contributions Conceptualization: Eric Wikramanayake, Xianji Wen, Fion Cheung, Aure´lie Shapiro.
