Innovation is the process whereby individuals or organizations bring new or existing products, processes or ways of organization into use for the first time in a specific context. Innovation in agriculture cuts across all dimensions of the production cycle along the entire value chain - from crop, forestry, fishery or livestock production to the management of inputs and resources to market access. This book represents the proceedings of the first International Symposium on Agricultural Innovation for Family Farmers which FAO organized at its headquarters in Rome, on 21–23 November 2018.
