Facilitators play a critical role in establishing and operating MAIPs, stimulating interactions among MAIP actors and thereby supporting co-innovation and co-learning processes. They are usually specialized MAIP actors (e.g. researchers, extension agents, agricultural educationists, brokers, NGO activists, traders and processors). Qualified MAIP facilitators, as value chain intermediaries and coordinators, are required to have strong facilitation skills and relevant technical background. They are normally trained through training of MAIP facilitator courses or through the implementation of a MAIP. This handbook aims to support MAIP facilitators to establish and operate MAIPs. It summarizes the experience of the MAIPs in persimmon, hazelnut and honey value chains that FAO implemented as part of the European Union-funded project “Development of sustainable and inclusive local food systems in north-west region of Azerbaijan (GCP/AZE/014/EC)”, the “Tropical Agricultural Platform Agricultural Innovation System (TAP-AIS)” project implemented in Malawi, and the Science and Technology Backyard (STB) initiative led by the China Agricultural University (CAU). It also draws on the experience of the training course “Training of master trainers for establishing and operating Multi-actors Agricultural Innovation Platforms” co-organized by FAO and CAU on 11–15 July 2023.
