DES MOINES, IOWA - Live coverage of the World Food Prize, honoring outstanding individuals who strive to improve the quality, quantity or availability of food throughout the world.

The 2012 World Food Prize was awarded to Dr. Daniel Hillel for his role in conceiving and implementing a radically new mode of bringing water to crops i­­n arid and dry land regions - known as "micro-irrigation.”

Dr. Hillel's pioneering scientific work in Israel revolutionized food production, first in the Middle East, and then in other regions around the world over the past five decades. His work laid the foundation for maximizing efficient water usage in agriculture, increasing crop yields, and minimizing environmental degradation.
