This special edition of the publication Policy in Focus, a collaboration between IPCid, the World Food Programme (WFP), and socialprotection.org, features 22 papers authored by over 50 experts from diverse institutions. It focuses on the barriers social protection systems face in achieving food security and combating malnutrition. Through case studies, expert insights, and policy analyses, the edition identifies key roadblocks such as funding gaps, political constraints, fragmented approaches, and implementation challenges. It also offers solutions to strengthen social protection systems, breaking cycles of hunger and poverty while envisioning them as a foundation for resilience and sustainable development.
