This policy brief reports on a recent study, implemented by RUAF Foundation and supported by the Food & Business Knowledge Platform (F&BKP) and the CGIAR Water, Land and Ecosystems Research Program (WLE/ IWMI), on the role of the private sector in building more sustainable and resilient city region food systems

Innovation is often presented as one of the main catalysts for more sustainable and inclusive development. In the agricultural and food sectors, innovation is characterized not only by specificities arising from its relationship to nature, but also from the wide diversity of its stakeholders, ranging from farmers to consumers, and including intermediaries such as the research community and advisory services. Innovation emerges from interactions between these actors, who mobilize resources and produce knowledge in collaborative mechanisms in orderto generate changes.

This article examines how research on the agriculture and agrifood systems mobilizes the concept of Innovation System (IS). A literature review on the IS provides an analytical framework for determining its theoretical frame of reference, its area of application and its uses.
