The objective of this workshop is to explore, from the participant feedback, the different ways and situations, related to agroecological transition, in which the knowledge production process are questioned and even renewed. In a collective and cross analysis, we will try to overcome the general discourse on the goal to create synergies between scientific, empirical and even more traditional knowledge to precise stakes, actors and organisations for “new” or different arrangements of a diversity knowledge production process. For that, this workshop will be organized as a “fishbowl conversation” in order to facilitate exchanges within the participants bringing together researchers and stakeholders (from teaching organizations, extension services, farmers etc.) and give time for each participant to give their proper insights in reaction to others experience feedback and analysis. The session will be moderated and divided into two parts. Each part will be introduced by a short introduction proposed by a researcher in order to frame debate and give key points : 1)Role and practices of intermediary actors (such as advisors) accompanying the agroecological transition. How does it change their role and postures in supporting, teaching, creating tools and managing organizations? This sequence will explore the (re)definition of intermediary actors skills in the way they contribute to the evolution to cognitive statements and process.
