A food system is the full set of processes, activities, infrastructure, and environment that encompass production, processing, distribution, waste disposal, and food consumption. Food systems are multidimensional, including sociocultural, economic, environmental, and political aspects, and complex, with multiple actors (food producers, food-chain actors, and consumers) managing multiple linked and nested agri-food value chains within dynamic and interactive food environments. Food systems also have multiple outcomes related to health, environmental sustainability and inclusion. Learn more about food systems from the resources below.
