Current analyses of issues relating to ethnicity and empowerment are silent about the significance of the environment in shaping and being shaped by human relations. For its part, environmental policy research, with few exceptions, has also ignored the dynamics of identity construction and cultural values that inform human relationships with the environment and thus affect environmental sustainability. I address this gap in the scholarship through an analysis of the Sardar Sarovar Project [SSP] in India. I explore the interweaving of the constructions of gender, ethnicity and empowerment and their implications for a new politics of the environment - the politics of environmental justice. I argue that discourses of modernization underpin the arguments of all those who discuss the SSP, whether in favour or against.
