The French Agency of Development carries out a line of research about water governance, as well as about the common. Within this context, this research project aims to deepen the knowledge of the interactions between large and small water systems in the current situation of water crisis in Bolivia, to analyze the issue of water territories (territories managed and experienced by the stake-holders) from the perspective of the commons; and more generally, seeks to understand the positioning, the interactions and the dynamics of the social and political stake-holders.
