Narmada Bachao Andolan (NBA) is an Indian social movement spearheaded by native tribals (adivasis), farmers, environmentalists and human rights activists against a number of large dam projects across river Narmada, which flows through the states of Gujarat, Madhya Pradesh and Maharashtra. Sardar Sarovar Dam in Gujarat is one of the biggest dams on the river and was one of the first focal points of the movement. It is part of the Narmada Dam Project, whose main aim is to provide irrigation and electricity to people of the above states.
