Climate Adaptation Knowledge Exchange (CAKE) is aimed at building a shared knowledge base for managing natural systems in the face of rapid climate change. CAKE is intended to help build an innovative community of practice. It helps users to get beyond the limitations of their time and the unwieldy thicket of books, papers and articles by Vetting and clearly organizing the best information available, Building a community via an interactive online platform, Creating a directory of practitioners to share knowledge and strategies, and Identifying and explaining data tools and information available from other sites. CAKE provides users with case studies, tools, community, and a virtual library about climate adaptation. The Case Study Database profiles on the ground adaptation projects and links to complete project information. The Tools section of CAKE directs you to the wealth of tools available online to help you process climate change information and make adaptation decisions.
