The Narmada Bachao Andolan (NBA) is a social movement in India that began in the late 1980s. It aims to protect the rights of people affected by the construction of large dams on the Narmada River, particularly the Sardar Sarovar Dam. The movement highlights issues such as displacement, environmental degradation, and the loss of livelihoods for local communities. Led by activists like Medha Patkar, the NBA has organized protests, rallies, and legal actions to advocate for the rights of those impacted. The movement emphasizes the need for sustainable development and equitable resource distribution, challenging the notion that large infrastructure projects benefit all.
