It isn’t often that we think a lot about food loss and waste. For example, have you ever thought about this: food waste and loss amounts to $1 trillion in economic costs. And how about these startling facts: 20 percent of land, seventy percent of water withdrawals, and thirty percent of energy are embedded in the food system.
Amy Quinton, who writes about science and agricultural research, has created a new podcast called Unfold. She co-hosts and co-produces the podcast with Alexa Renee. The first season of Unfold looks at how to sustainably feed an expected 10 billion people worldwide by 2050. Quinton will describe the goals behind doing a podcast on food waste and food loss. She will be joined by Ned Spang, an Assistant Professor in the Food Science and Technology Department at UC Davis.
Spang’s research focuses on the linked relationship between food, water and energy and finding efficiencies in those systems. He recently published an in-depth review of the causes of food loss and waste globally, as well as the environmental impact of food losses on farms.
