System viability approach is analysing how a system reacts, resists, changes and evolves in order to enable its own survival with facing a variety of environmental challenges. Moreover, viability constitutes a way to identify sustainable politics and actions through defining operational constraints, in terms of vulnerability and resilience. This last describes individual and social systems property to face a catastrophic change by resisting, adapting or transforming (Walker & al., 2004; Holling 2001, Scheffer & al. 2003). Nevertheless, systems approaches have been criticised for their inability to identify "bottom-up" processes, mainly refeering to participatory engagement within territorial challenges; This obviouly leads to the following question: is system viability an easy framework to be applied by local communities ? As explaining and identifying distinct environmental conditions and community responses to the viability challenge constitutes a complex activity for both scientific researcher and community participants, could viability indicators easily beeing understood by non-academic people ? Therefore, what type of methodological tools should enable participants to collect information to ensure a communitary viable territorial construction ? To provide answers to those questions, we'll present a participatory experimentation situated at Villeneuve le Roi, a 3-hectare pluriactive farm not far from Orly airport, Paris, France (Vialan 2012). This dynamical-insertion site tries to status this local environment as a communautary project, implying farming and gardening know-how transmission, environmental acknowledgment and cooking-baking practice.
