The U.S. Government Global Nutrition Coordination Plan outlines technical focus areas with substantial nutrition-related U.S. Government investments through which improved cross-government coordination could catalyze greater progress. Since its release in June 2016, much progress for improved cross-government coordination and collaboration toward nutrition is attributable to the Coordination Plan. This annual summary report, covering June 2016 through September 2017, outlines these accomplishments, identifies challenges to implementation, and reflects on how these results may inform priorities for future action.
