In this study, we seek to analyze the reconfiguration of traditional common property natural resources management in the Bolivian Altiplano. We focus on two intertwined commons, water and land. The modification of a role-playing game set up during the first phase of the project, by integrating these two new dimensions, allows us to understand the current state of these commons and their evolution. This participatory approach aims at validating the results of the previous diagnosis through the improvement and re-appropriation of the game model by the inhabitants of the communities. A qualitative analysis of the exchanges during the game sessions also enables a better understanding of the discourse around the collective management of water and land, the evolution of the community identity and the changes in the governance system. Through the use of the game, we hope to open an intergenerational dialogue on the future of the communities and the territory.
