This guidance note describes an approach aimed at improving food security and nutrition through education systems, with a specific focus on schools. Furthermore, the note intends to support policy-makers, advisors and other relevant stakeholders in promoting greater coherence between education, agriculture, nutrition and other policies and programmes; particularly, on how the policy agenda for the education sector can be leveraged for better nutrition and food security without compromising its own priorities. The policy note provides guidance on how to answer the following questions: What is the current food and nutrition situation of children, adolescents and the wider community related to education settings? What are the main education and other cross-sector policies and programmes that affect/influence food security and nutrition? What policy changes are needed to enhance the potential of education systems to achieve shared food security and nutrition objectives?
