“…Two researchers that participated in this process as the facilitator of a multiactor situation and as an intermediary in the co-production of knowledge respectively, act in the present study as reflective scientists (Pohl et al, 2010;Wittmayer and Schapke, 2014). With the aid of a boundary scientist external to the process, they report on the content of group discussions and its consequences for MPA management (Stratoudakis et al, 2015b-d;Batista et al, 2015) and on the evolution of the collaborative process and its wider tangible and intangible outcomes (Innes and Booher, 1999;Vasconcelos et al, 2012). The overall reflection takes in consideration "systematic institutional design" (Healey, 1997), i.e., the introduction of new rules and roles, while identifying the building up of an effective community of practice -"groups of people who share a concern or a passion for something they do and learn how to do better as they interact regularly" (Lave and Wenger, 1991) as a benchmark of success.…”
