This chapter explores “Chemins de transition,” an initiative that leverages its position within a knowledge institution to expedite socio-ecological transitions. Recognizing the potential of universities to contribute beyond their traditional roles, the project addresses pressing ecological challenges such as biodiversity loss, resource scarcity, and climate change. The chapter details the initiative’s origins, theoretical foundations, and a foresight-based methodology designed to mobilize over a thousand experts and stakeholders. This approach aims to develop new strategic planning tools for anticipatory governance and adapt them to societal needs. The project’s unique method combines academic, professional, and experiential knowledge to create a concrete narrative for transformation. Key aspects include the development of a “transition arena,” scenario planning, and participatory workshops that collectively envision desirable futures and outline trajectories to achieve them. The chapter also discusses the project’s learning outcomes, challenges, and success factors, emphasizing the critical role of participatory foresight in driving systemic societal change. This innovative approach has informed, trained, and engaged thousands of individuals and organizations across Quebec, demonstrating the importance of interdisciplinary collaboration and long-term strategic planning in achieving sustainable socio-ecological transitions.
