To improve human health and nutrition in sub-Saharan Africa, barriers that exist between the food and health systems need to be broken down, contends Per Pinstrup-Andersen, a 2001 World Food Prize laureate and the H.E. Babcock Professor of Food, Nutrition and Public Policy at Cornell.

Pinstrup-Andersen's book, "The African Food System and Its Interaction with Human Health and Nutrition" (Cornell University Press, 2010), launched on campus Nov. 23 with a panel discussion featuring Derrill Watson, Rebecca Nelson, Anna Herforth, Chris Barrett and Patrick Stover.
