An agropark is a cluster in which several primary producers and processors cooperate to enhance sustainable agro-food production. Because agroparks represent complex system innovations, this article studies their realisation trajectories from the stakeholder management perspective. By using the case study method, the research confirms that agroparks are system innovations involving many participants, most of them being key stakeholders. The different stakes and power positions, and their impact have been assessed. and managed in line with the realisation process of the agropark. The paper provides first learnings on stakeholder management in agropark projects, which may promote their realisation.
