This chapter conceptualizes community nutrition resilience. It draws on a literature review related to resilience, delineating the term from the related terms "sustainability, " "transformability," and "adaptability." It examines resilience in an urban setting and then among communities. Subsequently, it looks at food security and identifies nutrition as a critical component affecting the health, well-being, and opportunities of communities. It pays particular attention to how a changing climate affects food security. It then examines food systems and its constituent parts as the vehicle for delivering community nutrition resilience. Ultimately, it offers a definition of community nutrition resilience. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.
