Although there are agreed definitions of food security and nutrition and a common aid database, there is no common standard for tracking official development assistance (ODA) for food security and nutrition. This creates confusion and undermines donor efforts to achieve the Sustainable Development Goals (SDGs) and transform agrifood systems. This background note reviews the current definitions of ODA for food security and nutrition, assesses the implications, and proposes a new food security and nutrition aid tracker which would allow to develop a more coherent framework that will enable better targeting and use of ODA resources. Specifically, the new tracker would enable donors to better analyse, monitor, and track ODA resources provided to food security and nutrition, and the extent to which they are aligned with scientific evidence on how to end hunger sustainably. Better analysis, monitoring and tracking of resources in the system will ultimately enable better evidence-based decisions to select the highest priority countries, the most effective intervention areas and the scale of resources needed.
