Eco-Tourism as a Driver for Sustainable Regional Development Amidst Climate Change Realities in the Eastern Himalayas: A Study of Sikkim in India

The state of Sikkim in the eastern Himalayas has transformed its primarily farming-pastoralist economy into a thriving tourism and hospitality sector in recent decades. However, there are several emerging threats to the sustainability of the tourism industry in Sikkim. These include the changing state of Himalayan glaciers, human intervention through rapid urbanization and deforestation, and the exploitation of natural resources. Despite efforts to promote nature-based tourism over mass tourism, the overall tourism scenario in Sikkim is not eco-friendly. The high-altitude towns that cater to tourists, such as Lachung, Lachen, and Pelling, have become areas plagued by garbage and pollution. Water, air, and soil pollution resulting from unsustainable mass tourism practices are major concerns. This study, conducted through field research using questionnaires, evaluated the current state of village-based eco-tourism in Sikkim. Sikkim's cultural heritage and long-standing traditional beliefs that promote harmony with nature provide a strong foundation for a successful and sustainable nature-based tourism sector. The study also used a simple geometric forecast analysis method to predict the increase in population, water demand, and waste generation in Sikkim. The results highlight the rapidly growing urban centers in the state, such as Namchi and Gyalshing. Furthermore, water demand and waste generation are expected to rise significantly in the next three decades. To protect the ecosystem and ensure the region's socio-economic growth, it is imperative to shift from mass tourism to village and nature-based tourism practices. By embracing eco-tourism and implementing sustainable tourism practices, Sikkim can navigate the current climate challenges while ensuring the long-term viability of its tourism sector. By simultaneously focusing on sustainable regional development, the state can foster economic diversification, community empowerment, and a holistic approach to growth that respects the environment and preserves the region's unique natural and cultural heritage.
