In the global practice and research focus of sustainability aspects, tourism has also not been able to make its comprehensive understanding like many other sectors. It is widely accepted that the quest for search of universally acceptable definition or understanding of ‘sustainable tourism’ is difficult proposition. In recent years, sustainability theory has advanced through the articulation of possible interpretations of sustainable tourism and its applications (Butler, 2007) . It has passed through confusing state of the debate, followed by different articulations of sustainable tourism in frame of development of tourism on the principles of sustainable development (Butler, 2007), which is recent phenomena.
The frameworks, models, policies of such development have been faster in developed countries given context, economic development priorities and size of population and country, this has not been attention of the governments in emerging markets and developing countries for long, however tourism has been a major sector. The coordinated focus on sustainable development by all major multilateral stakeholders simultaneously has pushed governments to develop instruments of change, and implement practices, models and policies of sustainable tourism. Tourism has been mainstreamed like any other single or aggregator industry sector by policy makers with focused approach to sustainable tourism.
The interdisciplinary research in tourism and sustainable tourism domain is progressing to value chain, business models and efficiency in sustainability practices, start-up innovations, digitalisation, responsible financing, transformational models, stakeholder management, new skills management and other areas which are influencing the theoretical and practice modelling. The Sustainability+Tourism 2023 remains title for few years to produce research in the domain from different interdisciplinary areas. The theme for 2023 CESTour conference is Navigating the Future of Sustainable Tourism, which will have tracks and sub-tracks to present the researches in the main sustainable domain and application domains.
