This case study documents how the nutrition information systems in South Sudan, once weak and unreliable, have been transformed into a well-developed system supported by government, donors and Nutrition Cluster (NC) partners. It highlights how increased technical capacity in nutrition and information management within the Cluster Lead Agency (UNICEF) has allowed for the NC to focus on coordination. Integrating nutrition information management capacity into Ministry of Health (MoH) systems remains a work in progress. Summary: This case study details the limitations around the rapid expansion of nutrition services in Somalia in response to the 2011-2012 famine and the process undertaken to improve nutrition coordination, governance and service delivery in this complex context. Key learning from this process is identified.
