In an age of unprecedented globalization, our food supply chains — the institutions and mechanisms involved in food production and distribution — have become longer. So much so that they are hardly perceived as chains or systems. They have been integrated into our lives, and into our cities, and transformed our relationships with food. And yet, those very long food supply chains are implicated in some of our most pressing global problems, from food security and waste to biodiversity and climate change. These food supply chains have come to their current state, their current length, over decades, or centuries perhaps, through all sorts of political, social, cultural, and economic processes, and carry with them a range of burdens: vague producer-consumer relationships, and a host of negative environmental externalities, among many others.
