This paper presents a participatory modeling for multi-points of view description of a system from scientists' knowledge. The method is applied in the development of a generic model for agro-biodiversity dynamics in developing countries with a focus on crop genetics diversities evolution through the stakeholders' management at different scales. The model description is based on the knowledge of scientists from different disciplines and has been validated using role playing game with stakeholders in order to verify its relevance and coherencies. The model has been used to analyze the evolution of crops varietal diversity under two interventions scenarios: agricultural intervention and seeds intervention. The results show that agricultural interventions increase crop varietal diversity at global level more than the direct seeds interventions.
