SEED-DIV: AN ABSTRACT ROLE-PLAYING GAME FOR DISCUSSING COLLECTIVE MANAGEMENT OF AGROBIODIVERSITY
Résumé
This research aims at accompanying farmers in building a collective management of their subsidence cereals varietal diversity. Seed management and its impact on biodiversity dynamics are driven by farmers' individual choices and strategies on the one hand, and by the seed system functioning on the other hand. We think that the mutual understanding of the interactions arising in this complex system is a prerequisite to work together on the construction of new collective management rules to participe to agriculture sustainaibility coping with a large choice of varieties. Participatory conceptual modelling and Role-Playing Games were used in several workshops gathering researchers, NGOs, farmers' organisations and farmers. A result of this series of workshops is an ABM of an archetypal Malian village that represents the current situation where varietal diversity is managed individually but is freely available for the community. In this model, agents are farmers that make varietal choices and provoke seed exchanges depending on their individual strategies and external factors. All descriptive parameters hold qualitative abstract value so that the model can become the support of generic discussions between farmers from different regions. Through the workshops, this model was built and validated with the active input of local stakeholders and scenarios of collective management were constructed. Then the model will be used as a prospective tool for simulating these scenarios of various forms of collective action.
