Résumé : Landscape modelling integrating spatial information in Geographic Information Systems has been widely used to represent knowledge and support decision-making in the field of natural resource management. However, creating suitable visual representations of the landscape and its dynamics to stimulate the participation of diverse stakeholders in co-management of the land is still needed. This paper focuses on the design and implementation of a virtual landscape based on iconic representation used with herders and foresters, which both of them have contrasted perceptions on forest regeneration, to observe vegetation dynamics and emerging landscape features depending on different cattle and forest management strategies. This spatial interface was used during computerassisted Role-Playing Game sessions as part of a Companion Modelling process aiming at facilitating learning and support decision making among the concerned stakeholders in an upper watershed of northern Thailand. Before designing the spatial interface used in the model, an historical analysis of land use and land cover changes based on remote-sensed data was carried out, as well as a field survey on the impact of cattle grazing on vegetation dynamics. Then, the first set of vegetation states and their dynamics were produced and were validated with herders and foresters later. Thereafter, the simplified landscape representing landscape heterogeneity was constructed and used in two gaming and simulation field workshops. The different patterns of landscape emerged from herders' and foresters' decisions and interactions stimulated them to think about how to manage agro-ecosystems. Both of them agreed to implement a pilot plot of Brachiaria ruziziensis pasture in reality after finish the second workshop. This process proved to be instrumental in facilitating communication among the parties in conflict and increasing their motivation to improve the current situation. However, the use of such virtual landscape in gaming sessions proved to be time consuming and the managed area as well as the number of players was limited. Therefore, to get rid of these constraints, a fully autonomous Agent-Based Model making use of the same kind of simplified virtual landscape will be developed and used with local stakeholders to run possible future scenarios of change in a more time efficient and inclusive way.
