The SecureNutrition Series on Nutrition-Sensitive Social Protection is intended to augment the available guidance on improving nutrition through multisectoral approaches, and inform ongoing and future efforts to improve nutrition outcomes through investments in the social protection sector. Since publication of the World Bank's "Improving Nutrition Through Multisectoral Approaches" in 2013, numerous development partners have explored the mutual synchronicities between social protection and nutrition and the levers (e.g. conditionality, targeting, payment beneficiary and frequency, etc.) that can be manipulated in order to enhance impact on nutrition outcomes. The three Series' documents - an Evidence Review, a suite of Case Studies, and a Global Forum Report - build on this continued line of operational research. Collectively, the documents are an attempt to establish a snapshot of current nutrition-sensitive social protection approaches, explore in more detail how these programs are being implemented, and outline areas of future operational research. This series is an extension of the Global Forum on Nutrition-Sensitive Social Protection Programs held in Moscow in September 2015. Recordings from past learning seminars on the same topic are hosted by SecureNutrition: www.securenutrition.org.
