This study aims to examine the scope for sustainable tourism development in Sunamganj, Bangladesh, by using its natural resources with local community involvement and introducing appropriate policies. The objective is to understand the subject extensively through a framework that supports eco-friendly tourism in the areas while keeping socio-cultural and economic factors in view. This is a mixed-methods study that combines both qualitative and quantitative data. The primary factual data is obtained through on-the-spot surveys, interviews, and feedback from 60 tourists. The analysis draws on secondary data from extant literature, government reports, and case studies of sustainable tourism. Research results showed that though Sunamganj has natural attractions such as Niladri Lake, Tanguar Haor, Jadukata River, Biki Bil, and Shimul Bagan, due to a lack of infrastructure and policy support, tourism in Sunamganj remains undeveloped. However, there is a vast scope for ecotourism and community activities that could benefit the local population. The chapter focuses on the coverage, especially for Sunamganj, and does not evaluate larger regional effects. Further study should be conducted to determine if similar strategies can be instituted in other districts of Bangladesh. Suggestions range from improving infrastructure, promoting ecoresorts, to implementing community-based tourism and synergic partnerships between the private and public sectors. Policy measures should focus on promoting ecotourism and providing more incentives for sustainable practices. This paper offers a novel approach linking sustainable tourism guides with community development and policy frameworks. It offers insights for policymakers and tourism operators interested in developing ecotourism in uncharted territories such as Sunamganj.
