This thesis disentangles the complex dynamics of water and mining conflicts, seeking to understand how environmental (in)justices related to the water use of mining companies emerge and can be addressed. To do so, it focusses on institutions that regulate water use and natural resource extraction, discourses that legitimize and normalize certain social-environmental actions while rendering others unconceivable, and practices of governing the intersection of water and mining. Specifically, it pursues the following questions: 1. What are the factors or combinations of factors that explain how water and mining conflicts develop and evolve, according to existing academic literature? 2. What are the transnational institutional regimes that govern mining-related water use? Which forms of water use do they recognize and into which discourses are they embedded and gain authority from? 3. How do institutional legacies, discourses and political economic or material contexts impact efforts to (re)shape water- and miningscapes via the implementation of water protection legislation or provisions for public participation? 4. How do notions of ‘appropriate’ social-environmental interactions emerge through the interplay of different rationalities and how do they articulate themselves in practices of governing water and mining? 5. What are the conceptual and practical implications of these findings for the pursuit of environmental justice? How can (contested) institutions, discourses and practices be researched and (re)shaped to promote just social-environmental interactions? Questions 1-4 are answered in the main body of the thesis (Chapters 2-5), while the concluding chapter (Chapter 7) addresses the final question. The thesis moves from global dynamics and rule-setting to place-based interactions and meanings, placing a geographical focus on Mongolia. It applies a multi-method approach, combining systematic synthesis with in-depth, interpretative analyses and drawing on concepts
