This report and related activities seek to deepen understanding of, and enhance action to address, the impacts of climate change on food security and human mobility as part of Where the Rain Falls : Climate Change, Food and Livelihood Security and Migration (« Rainfalls »). The project is possible due to generous support from the AXA Group and the John D. and Catherine T. MacArthur Foundation, particularly the guidance of Alice Steenland, John Slocum, and Milena Novy-Marx. We would like to acknowledge the Rainfalls researchers upon whose case studies part of this report is based.
