This report presents conclusions from a two-day Financial Innovations Lab® on catalytic financing for nutrition facilitated by the Milken Institute in May 2013. Participants included a broad mix of government representatives from countries that have been affected by undernutrition, as well as bilateral and multilateral donors, foundations, representatives of private businesses, and finance and nutrition experts. The Lab reviewed proposals emerging from the Steering Committee on Catalytic Finance established under the auspices of the Scaling Up Nutrition (SUN) Donor Network, an informal group of existing donors in nutrition.
