Vertical integration is essential for scaling up climate change adaptation action. The process of strategically linking adaptation efforts by key actors at local, sub-national, national, transboundary, and international levels in all phases of the National Adaptation Plan (NAP) process was explored at NAP Expo 2023. This session was co-hosted by the NAP Global Network and the Euroclima program through the Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) and the Economic Commission for Latin America and the Caribbean (ECLAC) on March 29, 2023. The event featured speakers from Kenya and Chile who shared their experiences with vertical integration in adaptation.
