A Study of Critical Success Factors Influencing Sustainable Tourism in India

India is a country with ‘Unity in Diversity.’ It has a favourable environment for tourism to a great extent. A key element of India's strategy for both environmental preservation and economic growth is sustainable tourism. The purpose of this study is to investigate and assess the critical success factors (CSFs) that support the successful adoption of sustainable tourism in different Indian states. Stakeholder collaboration, infrastructure development, policy support, community involvement, and ecological impact awareness are all critical to the sector's long-term sustainability, according to the research, which integrates environmental, sociocultural, and economic aspects. The study is descriptive in nature, collecting insights from stakeholders like local communities, visitors, and private operators, as well as qualitative interviews with tourism officials. The results emphasize how important it is to promote sustainable tourism through decentralized governance, responsible visitor behavior, and the incorporation of traditional knowledge systems. Kerala, Sikkim, and Ladakh are examples of regions that set the standard for ecotourism and community-led tourism best practices. Green certifications, sustainable financing methods, and digital transformation are also acknowledged as new enablers. In order to improve sustainability performance and match tourism initiatives with the Sustainable Development Goals (SDGs) of the UN, the study offers policymakers and industry stakeholders strategic recommendations. This study adds to the expanding conversation about inclusive, climate-resilient travel that balances India's development and conservation priorities.
