The Narmada Bachao Andolan is a social movement against large dams being built on the Narmada River in India, including the Sardar Sarovar Dam in Gujarat. The movement was started in 1986 in response to the World Bank funding the dam project without properly considering social and environmental impacts. It is led by social activist Medha Patkar and aims to save forests, wildlife, and ensure proper resettlement of thousands of people displaced by the dams. While supporters argue the dams will provide water and power, critics say they negatively impact tribal communities along the river without adequate rehabilitation. The movement has involved protests and legal challenges, with the Indian Supreme Court ultimately ruling in favor of continuing dam construction.
