Step 1: Understanding the context of the Narmada Bachao Andolan (NBA)
The Narmada Bachao Andolan was a social movement in India initiated in the 1980s. It protested against the construction of large dams on the Narmada River, such as the Sardar Sarovar Dam.
Step 2: Identifying the core issue addressed by NBA
The construction of these dams was expected to submerge a large number of villages, displacing thousands of people, including indigenous communities and farmers.
Step 3: Analyzing the options
Option (1): Industrial development was not the primary target.
Option (2): Correct. The movement opposed the large-scale displacement of local populations.
Option (3): Though some land was submerged, the core issue was not just the loss of irrigated land.
Option (4): The movement was not centered on forest department control.
Step 4: Conclusion
Hence, the correct answer is (2) Large scale displacement of the local people.
