Note générale : The human environment interaction influences the natural resource management. It needs to be clarified and understood by concerned stakeholders to ensure practical development. In lower northeast Thailand, the interaction between water dynamic of rainfed lowland rice ecosystem and labour migration plays a crucial role in shaping this agricultural community. Farmers' decision-making processes with regard to on-farm activities are generally determined by water and labour availability. The Royal Thai Government has been trying to alleviate the climatic risk by building small-scale water retentions but the impact is still limited. In this research, an innovative approach, Companion Modelling (ComMod), is used to build collective comprehension regarding such interaction via an associated key tools, Role-Playing Game (RPG) and Multi-Agent Systems (MAS) model with stakeholders throughout the research process. A comprehensive knowledge of interactions and representation of system components would help to design more adapted investments. Therefore, this research aims at understanding and modelling the interactions between water dynamics, land use, and labour migration. The hydrological model was built to represent the water balance, soil properties, and land-use types. Based on the initial conceptual model, rulebased social agents are implemented to represent the decision-making processes of heterogeneous stakeholders regarding farm and off-farm employment. The paper shows how a MAS model is used for collective discussion and scenario exploration with the stakeholders. The results of the game sessions and their use for improving the model are also presented. Finally the results of the simulation of a baseline scenario are discussed. (Résumé d'auteur)
