This report is the output of an online learning event on Climate Change Adaptation held in January 2025, hosted by CARE International UK in collaboration with the Global Shelter Cluster’s Environment Community of Practice. The learning event focused on integrating climate resilience into humanitarian shelter and settlement programming and aimed to bridge knowledge gaps, identify best practices, and enhance collaboration. It brought together shelter practitioners, climate specialists and others to explore the WHY, WHAT, HOW and WHAT NEXT of integrating CCA with shelter and settlements programming. Participants explored how CCA fits within broader environment and disaster risk reduction spheres of activity. Examples of entry points for CCA in the typical response cycle - preparedness, response, recovery and reconstruction - were highlighted. Existing tools and resources that can guide and enhance CCA within shelter and settlements (and multisector) programming were shared. Case studies from Zimbabwe, Mali and Nigeria, and Vietnam showcased. Key outcomes of the event included increased awareness, knowledge sharing and actionable recommendations. The concluding comments and recommendations in the What Next? section of this report were derived from analysis of all contributions to the learning event. They intend to prompt further reflection and suggest next steps for enhanced climate-smart humanitarian action. An open invitation exists for interested parties to continue these discussions and access further learning opportunities through the Global Shelter Cluster’s Environment Community of Practice.
