The Food for Humanity Action Collaborative is building a collaborative network that advances and supports fresh approaches to interdisciplinary research and educational offerings on healthy and sustainable food systems. The collaborative network will engage faculty and researchers from across Columbia University, form a crucial part of the Climate School, and support Columbia’s efforts to bring academic knowledge to work in the world, identified by President Bollinger as the University’s Fourth Purpose. The network will develop collaborations across Columbia and beyond around: 1) education, 2) collaborative research and practice, and 3) engagement and outreach. The action collaborative will frame its work through multiple lenses that collectively determine the health and sustainability of food systems, including nutrition and health equity; economics and policy incentives for healthy food systems; interaction of food systems with climate and land use; community engagement for healthy diets; and food systems under shocks, conflict, and migration.
