This publication was jointly prepared by the Food and Agriculture Organization of the United Nations (FAO) and the International Fund for Agricultural Development (IFAD) as a technical input to the G20 Food Security Task Force in 2025. It provides insights on policy instruments and agrifood system approaches aimed at promoting food security and enhancing the effectiveness, sustainability, and resilience of agrifood systems at national, regional and global levels. Section 1 introduces the main challenges confronting agrifood systems today, including structural vulnerabilities, climate-related risks, and systemic inequities. Section 2 takes stock of global progress towards achieving Zero Hunger, drawing on available data and trends. Section 3 highlights a selection of policy options and best practices that are driving agrifood systems transformation and presents a group of 35 policies to highlight how they can impact different thematic areas, and the potential to group policies synergistically. The last section concludes with a set of recommendations for consideration by the G20 members.
