CAMBRIDGE MA, Apr 06 (IPS) – The battle for the future of food has grown contentious, and José Graziano da Silva has become a lightning rod for criticism. In 2014, as Director General of the United Nations Food and Agriculture Organization (FAO), he presided over the institution’s first International Agroecology Symposium, opening what he called “a new window in the Cathedral of the Green Revolution.” The FAO has since then formalized support for “Scaling Up Agroecology” while continuing to promote the kinds of chemical-intensive agriculture associated with the Green Revolution.
