In this chapter, we explore the politics of interdependencies through situated entanglements with water. Framing more-than-human interdependencies within feminist political ecology means starting from an understanding of relationality. Drawing on research with waters and communities in Maharashtra, India and the Tagus River in Spain, we focus on the co-constitution of embodied subjectivities with the more-than-human, addressing issues of well-being, illness and ecological change in contemporary waterscapes. In doing so we explore the contradictions, tensions and ethical implications of situated more-than-human co-becomings.
