Today is World Food Day. Observed every year since 1981, it focuses on the problem of hunger around the globe. Also, this week is the World Food Prize Symposium in Des Moines and some of the most innovative thinkers in the fight against hunger have come to Iowa.
Host Charity Nebbe discusses the foundations of sustainable development and what it will take to feed the world with Louise Fresco and Per Pinstrup-Andersen, two presenters at this week's symposium. Fresco is the former Director of Research and Assistant Director-General for Agriculture at the Food and Agriculture Organization of the United Nations and Pinstrup-Andersen is a World Food Prize Laureate from 2001 and the former Director-General of the International Food Policy Research Institute.
