Using Circular economics Strategies to Manage Tourism on Remote Islands:A SMART Approach

引用

Journal of Tourism and Hospitality Management 2024年第1期12卷 18-33页

作者： Colm Barcoe.james Hanrahan Garvan Whelan Ballsbridge College and ATU SligoIreland ATU SligoIreland TU DublinIreland

Circular economics theory offers destination managers of remote islands a solution-oriented approach to environmental sustainability. This paper examines the practical benefits of this theory that will support the development of a circular economy regarding sustainable island tourism (SIT). The aim of this paper is to inform discussions regarding the feasibility of applying a practice theory that emphasises changes in the behaviours across three segments, visitors, residents, and enterprises using SMART technologies. To achieve this objective, a SMART indicator system (SIS) was used to identify current practices that would support a circular economy (Ce). The key innovation of this study is the creation of a proposed framework that may inform best practices for SIT in the future. The findings highlight the potential opportunity of evidenced-based planning to deliver a circular economy strategy (CeS) for remote islands in the future. These insights can potentially impact the way that local authorities and destination managers approach the planning of tourism for six islands along the west coast of Ireland.
