Exploring sustainable tourism research trends: A literature review of the last decade

Abstract

Sustainable tourism has emerged as a critical focus in contemporary discussions surrounding environmental conservation and social responsibility. As global tourism continues to expand, the need for sustainable practices becomes increasingly urgent to mitigate adverse impacts on natural ecosystems and support local communities. This article presents a systematic literature review dedicated to exploring the key research trends in sustainable tourism from 2015 to 2024. The review aims to synthesize existing knowledge and highlight the importance of sustainability in the tourism sector. Data for this review was collected from the Scopus database, utilizing the keywords "sustain* tourism". This search yielded a total of 620 articles, reflecting a robust body of research in this vital area. A thematic evolution analysis was subsequently conducted to map the most prominent research areas and uncover existing gaps and opportunities for future inquiry. By focusing on the evolution of themes within the field, this study provides insights into both current and emerging topics relevant to sustainable tourism. Findings show that, the themes in sustainable tourism research have shown both divergence and convergence over time. From 2015–2019, "sustainable tourism" split into "sustainable tourism," "governance," and "development" by 2020–2022, with the latter two peaking during this period. Simultaneously, topics like "community participation," "place attachment," and others converged into "sustainable tourism." By 2023–2024, research trends displayed greater specificity. The findings from this literature review are importance to various stakeholders, including academics, policymakers, businesses, and governmental agencies. By offering a thorough perspective on sustainable tourism research, the review aims to facilitate informed decision-making processes and foster the development of more effective strategies that address sustainability challenges within the tourism industry. Furthermore, this article serves as a vital resource for guiding future research endeavours and practical applications aimed at resolving the complex issues associated with sustainability in tourism. Ultimately, the emphasis on sustainable tourism practices not only contributes to the conservation of natural and cultural resources but also ensures the well-being of local communities and the overall health of tourist destinations. By fostering collaborative efforts, this review underscores the importance of integrating sustainability into the core of tourism development strategies for a more equitable and sustainable future.
