The document discusses public policies for mainstreaming climate-smart agriculture (CSA) at large scales. It asks (A) if existing policies support CSA, (B) how to motivate policymakers to integrate CSA, and (C) constraints in integrating research into policy. For A, there is no specific CSA policy and it needs to be included in agriculture policies. For B, building consensus with research evidence and awareness at global and local levels can motivate policymakers. For C, constraints include lack of communication between researchers and policymakers, insufficient resources, and research not aligned with government priorities.
