Based on fifteen years of in-depth fieldwork on four continents, Daniel Warshawsky illustrates how and why food banks proliferate across the globe even though their impacts may be limited. He suggests that we need to reformulate the role of food banks. The mission of food banks needs to be more realistic, as food surpluses cannot reduce food insecurity on a significant scale. Food banks need to regain their institutional independence from the state and corporations, and incorporate the knowledge and experiences of the food insecure in the daily operations of the food system. These collective changes can contribute to a future where food banks play a smaller but more targeted role in food systems.
