This book’s analysis of the complex inter-governmental networking eliding the local governance of rivers with voluntary sector community-outreach and European Union directives identifies new locations of ecological activism precipitated by political affinities, which have become simultaneously public and private. The capacity of river heterotopias to intersect the public and private spheres of urban cities emphasises the intrinsic reproductive labour time of river restoration; for, as Foucault suggests, the heterochronies of urban heterotopia are one and the same time “outside of time”, while also constituting “a sort of perpetual and indefinite accumulation of time in an immobile place”. The book shows that the intersecting heterochronies of the urban river space confirm this Other Space as an intriguing gendered heterotopia.
