Craig Gundersen, distinguished professor of agricultural and consumer economics in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois says that the Supplemental Nutrition Assistance Program (SNAP) is effective in addressing the right to food in the U.S., and that the program can serve as an example for countries that struggle to provide food for all citizens.
Gundersen discusses how SNAP achieves a "right to food" in an article published in the American Journal of Agricultural Economics.
