Narmada Bachao Andolan — Environmental Laws

Entry	Year	Description	Impact
42nd Amendment	1976	Introduced Article 48A (Protection and Improvement of Environment and Safeguarding of Forests and Wild Life) as a Directive Principle of State Policy, mandating the state to protect and improve the environment. It also added Article 51A(g), making it a fundamental duty of every citizen to protect and improve the natural environment.	While not directly a result of NBA, this amendment provided a constitutional anchor for environmental protection, which NBA later invoked in its legal arguments. It strengthened the legal basis for environmental concerns and the state's responsibility towards ecological preservation, influencing subsequent environmental legislation and judicial interpretations.
73rd and 74th Amendments	1992	These amendments institutionalized Panchayati Raj Institutions (PRIs) and Urban Local Bodies (ULBs), respectively, granting them constitutional status and powers. They aimed at decentralizing governance and empowering local communities.	NBA's emphasis on local community participation and self-governance resonated with the spirit of these amendments. While NBA's struggle predated their full implementation, the amendments provided a framework for greater local involvement in development decisions, which was a core demand of the movement. This indirectly strengthened the voice of affected communities in project planning and implementation, aligning with NBA's advocacy for grassroots democracy.
