Humanitarian-development collaboration must be strengthened at all levels, according to a joint study on humanitarian-development collaboration for nutrition2 outcomes. The report, commissioned by the Global Nutrition Cluster and Scaling Up Nutrition, covers three case studies carried out in Afghanistan, Myanmar and Niger. It describes challenges and lessons learned and gives recommendations for humanitarian and development actors at global, national and local level on how to strengthen collaboration for nutrition. Creation of space is recommended, so that humanitarian and development partners can link up and develop specific and shared nutrition objectives, and afterwards implement these through national multisectoral plans. The report also calls for strengthened inclusion and accountability with and to national authorities and communities, as well as reporting against action plans.
