La modélisation collaborative pour stimuler l’émergence d’un système agricole plus durable.Conception et mise en oeuvre d’une démarche sur le plateau de Valensole

Abstract : Collaborative modeling aims at fostering the sharing of representations and learning among different stakeholders through the co-design and use of a model. The central question of this thesis is to analyze how such an approach, centered on agricultural systems assessment, can fulfill these objectives to eventually enhance the sustainability of the agricultural system. To this end, I have designed and implemented a collaborative modelling approach in the agricultural system of the Plateau de Valensole, a 80 000-hectare territory located in Southeastern France. A first step aimed at formulating the problem tackled by the approach in a participatory manner to engage the stakeholders in a collective dynamic. I developed a method of preliminary diagnosis that led to the identification of the stakeholders, the issues faced by the agricultural system according to them, and the diversity of their representations. Then, an agent based model was co-designed with the stakeholders to represent and assess the agricultural system through a set of environmental and economic indicators defined at field, farm and regional scales. The final step concerned the analyses of the results and the exploration of prospective scenarios. I discuss in this thesis the quality of the model (related to its assigned goals), the influence of the context on the approach, the participatory process in itself as well as the effects produced by the approach.
