This special issue of the Journal of Hunger & Environmental Nutrition identified research opportunities to develop successful interventions within agriculture, food, and health systems, as well as policies and actions for moving toward and achieving community environments that allow healthier diets and reduced obesity.

This dynamic collection of articles is the outcome of the Airlie Conference held in April 2009 that focused on the food system, food, agriculture, and agriculture policy which are central to a discussion on healthy diets and obesity prevention. More than 80 leading thinkers nationwide from the health, nutrition, obesity, and health policy domains, together with those from the sustainable agriculture, economics, and agriculture policy sectors, participated in this robust dialog.
