A food system considers the multiple activities, resources, and actors engaged in producing, processing, distributing, and consuming food. These are all shaped by, and interact with, everything from soup to nuts – i.e., all the environmental, social, political, and economic boundary conditions that determine what type of food can be produced where, how it is used, and by whom. All these elements are strongly influenced by global change drivers such as population growth, changing consumption patterns, biodiversity loss, and climate change. Given that our food systems are already struggling to bring home the bacon (i.e., to deliver on their intended outcomes of global food and nutrition security) these increasing pressures will catapult our tasks out of the frying pan and into the fire.
