Walter Orr Roberts Memorial Public Lecture: Food Security in the 21st Century: New Thinking on an Age-Old Problem

Authored by: 

The global food system is vast and complex, but how secure is it? Dr. Rosamond Naylor, Senior Fellow and Founding Director, Center on Food Security and the Environment, explores the food system starting with civilization’s domestication of grains from hybrid crossing to modern genetic modification techniques, considering the trade-offs inherent in feeding the world’s growing population. Dr. Naylor explores possible solutions to the vexing problems of climate change, resource depletion, population growth, changing diets, poverty, and conflict.
