Open innovation for sustainability in the agri-food sector: why, who and how?

Purpose This paper examines open innovation (OI) based on sustainability principles within the agri-food sector. The study aims to understand the interplay between different actors and develop a typology of their roles in fostering sustainability. Three key research questions guided our inquiry: “WHY” sustainability is driving the OI initiatives as presented by companies, “WHO” participates in OI interactions and “HOW” these interactions are structured among diverse agri-food actors. Design/methodology/approach Through a theoretical prism encompassing OI modes, types, practices, sustainability dimensions and multilevel perspectives, we analyzed 78 agri-food sustainable OI initiatives, as described by the companies, to identify and explain why, who and how they engage in OI to drive sustainability shifts. Findings The results reveal typical patterns of transaction and cooperation between actors and confirm the collaborative nature of sustainable OI in the agri-food sector when actors must transcend traditional economic boundaries and reshape both the internal performance culture and the broader industrial or community mindset. The paper also conceptualizes the roles of actors in co-creating value in the context of sustainable food transitions. Originality/value This study brings the theoretical lenses of OI to conceptualize the collaborative nature of sustainability transitions in the agri-food system. The focus on sustainability transitions is dominantly placed on innovators at the niche level, while incumbents tend to be depicted as protecting the status quo. Thus, the focus on the collaborative interplay among different actors engaged in OI for sustainability contributes to offering a more nuanced view of innovation in sustainability transitions. In turn, the development of a typology of actors, motivations and configurations of OI from sustainability transition perspectives contributes to strengthening the conceptualization of sustainable value co-creation in the OI realm.
