In an exploration of the processes through which urban India acquires or loses green spaces, this article examines how parks and urban publics are mutually constituted in Delhi. Social change has led to a re-imagination of cultural meanings and modes of ecological management. Ecological change, in turn, has created new social relations around the use and protection of nature. Analysing Mangarbani, a sacred grove on the edge of the metropolis, and the Delhi Ridge, a “wilderness” domesticated for recreational use, the author argues that the creation and preservation of certain forms of urban nature relate to the shifting sensibilities of elites, especially the section that acts as a self-appointed vanguard of environmental causes. However, other users of public green areas challenge the far-reaching effects of this “bourgeois environmentalism.” The contested meanings and practices around urban natures create new alliances and understandings that may promote ecology and justice.
