The chapter explores the potential pathway for scaling-up nature-based solutions in climate resilient infrastructure from the perspective of coastal ecosystem resilience. While evidence from the updated NDC submissions suggest an uptick in the perceived role of Nature-based Solutions (NbS) in mitigating and adapting to climate change, normative thinking on climate resilient infrastructure still relies largely on hard-engineering solutions. This will remain to be the case unless approaches like nature-based solutions are mainstreamed into thought, decisionmaking and planning processes. However, it’s a long road from the recognizing the opportunities and multiple dividends that NbS can mobilize to actually implementing NbS at scale. This chapter suggests the EAST (Evidence-based Adaptive Systems Transformation) Pathway for inclusion and mainstreaming of NbS for climate resilient infrastructure.
