Many agrifood development projects and programmes aim to support evidence-based and inclusive policies by organizing policy dialogues. Yet, despite their widely recognized importance, there is little guidance available to date on how to organize effective policy dialogues that are inclusive of diverse stakeholders. This training guide has been developed to address this gap by providing clear and comprehensive guidance on multistakeholder policy dialogue in agrifood systems. This guide also brings the added value of a clear focus on promoting innovation through smart, inclusive and collaboratively developed and implemented policies. The guide is divided into six modules that cover the key concepts, tools and approaches to support participatory, inclusive and evidence-informed policy processes and has been developed in the framework of the European Union-funded "Developing capacities in agricultural innovation systems: scaling up the Tropical Agriculture Platform Framework" (TAP-AIS) project. The training programme outlined in this guide has been implemented in adapted forms in six countries (Cambodia, Colombia, Eritrea, Malawi, the Lao People’s Democratic Republic and Rwanda) and with regional stakeholders in the Asia-Pacific region in the framework of the TAP-AIS project. Experiences and lessons learned from the implementation of this training are presented throughout the guide enriching it and bringing its conceptual background into practical application. Overall this guide is intended to serve as a valuable resource for changemakers globally supporting them to facilitate effective and inclusive policy processes and outcomes contributing to the sustainable transformation of agrifood systems.
