On today's River to River the 2012 World Food Prize laureate, Daniel Hillel, talks about his role bringing advanced irrigation techniques to crops in arid and dry regions in the Middle East. Hillel has impacted farming lands in more than 30 countries with his technique of “micro-irrigation” that keeps the soil continuously moist without overusing the water supply.
Also on this program of River to River, Jo Ann Jenkins, the president of the AARP Foundation, discusses the issues surrounding hunger in the older population.
