Food systems around the world face a triple challenge: providing food security and nutrition for a growing global population; supporting livelihoods for those working along the food supply chain; and contributing to environmental sustainability. Better policies hold tremendous promise for making progress in these domains. This report focuses on three questions. What has been the performance of food systems to date, and what role did policies play? How can policymakers design coherent policies across the triple challenge? And how can policymakers deal with frictions related to facts, interests, values, which often complicate the task of achieving better policies? It emphasises that robust, inclusive, evidence-based processes are thus essential to making better policies for food systems.
