The Medford Public Library presents an online question-and-answer session with professor Daniel Warshawsky, author of the book “Food Waste, Food Insecurity, and the Globalization of Food Banks.” The book analyzes the development of food banks across the world and the limits of food charity as a means to reduce food insecurity and food waste. Based on 15 years of in-depth fieldwork on four continents, 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. Warshawsky is an associate professor in the School of Social Sciences and International Studies at Wright State University in Ohio.
