In India, a varied, democratic country with a growing population and complicated sociopolitical dynamics, CSOs shape policymaking. This report examines CSOs' diverse influence on Indian policymaking. The study examines how CSOs influence legislators, advocate for change, and help create, execute, and evaluate policies using academic literature, case studies, and empirical data. Indian CSOs work on human rights, environmental preservation, social justice, healthcare, education, and government change. They represent marginalised voices and promote inclusive and participatory decision-making as mediators between people and the government. CSOs challenge legislators, raise awareness of important problems, and provide community-driven policy solutions via lobbying, advocacy campaigns, research, and grassroots mobilisation. The study also discusses CSO policy advocacy difficulties and prospects. Limited resources, bureaucratic impediments, political co-optation, and intense stakeholder reaction are among these problems. CSOs use their networks, experience, and grassroots legitimacy to overcome these barriers and effect change.
