This systematic review explores the intersection of smart technologies and sustainable ecotourism, aiming to enhance environmental conservation and promote sustainable development. The study follows PRISMA guidelines and uses databases such as ScienceDirect, Jstor, Taylor & Francis, and IEEE to identify scholarly, peer-reviewed studies from developing countries. The Joanna Briggs Institute and Cochrane Risk of Bias tools are employed to assess study quality, and thematic analysis techniques are used to extract and synthesize data. The review identifies 29 high-quality studies out of an initial 9583 records, focusing on the role of IoT in promoting sustainable ecotourism. Key findings include the diverse and important role of IoT in ecotourism, the challenges and opportunities associated with smart technologies, and the need for collaboration between governments, local stakeholders, and organizations to implement sustainable policies. Smart ecotourism involves multiple stakeholders and emphasizes dynamic interactions, co-creation of value, sustainable development, resource sharing, and innovation services. Technologies like IoT are crucial for sustainable tourism management, and their effective use can enhance operational efficiency while reducing environmental impact. The study highlights the importance of partnerships, education, and capacity building in successful implementation. The review also discusses the economic benefits and negative impacts of tourism, emphasizing the need for sustainable practices. It underscores the need for further research and critical evaluation of smart ecotourism to ensure responsible and sustainable development. The findings provide insights into the global implementation of smart ecotourism techniques and the significant impact of technology on promoting sustainable tourism models.This systematic review explores the intersection of smart technologies and sustainable ecotourism, aiming to enhance environmental conservation and promote sustainable development.
