Shanna Ratner made a pair of presentations about wealth creation and food value chains this spring at Cornell, her alma mater. Helen Schnoes discussed one of Shanna’s presentations in a June 2013 post on the Food Day blog. http://www.foodday.org/collective_impact_finding_inspiration_in_local_food_systems_reform
