The Climate Adaptation Knowledge Exchange (CAKE) was founded by the non-profit organizations EcoAdapt and Island Press in July 2010, and is managed by EcoAdapt. CAKE aims to build a shared knowledge base for managing natural and built systems in the face of rapid climate change and is intended to help build an innovative community of practice. It helps users go beyond time limitations 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 consists principally of four interlinked components: case studies, a virtual library, a directory, and tools. It also houses Community Forums for the discussion of current issues in climate adaptation:

• Opportunities Forum
• Advice Column
• Calendar
• Discussion Forum
• Workshop Support Pages

Registered users can submit case studies, recommend resources and tools, add organizations to the directory, post events to the calendar, and submit job or funding opportunities.
