The State of Food Security and Nutrition in the World 2021

Abstract

Multi-sector nutrition programmes (MSNPs) have gained increasing prominence over the last two decades to address the many direct and underlying determinants of malnutrition. Both the recent Lancet Maternal and Child Undernutrition Progress series1 and the Lancet Series on Adolescent Nutrition2 stress the importance of effective multi-sector programmes to prevent and tackle malnutrition at every life stage. However, there are still large gaps in our knowledge on the efficacy, effectiveness and impact of multi-sector approaches compared to single sector interventions, due to limited information on appropriate methods for monitoring and evaluating MSNPs.
