In less than two years, the concept of overtourism has come to prominence as one of the most discussed issues with regards to tourism in popular media and, increasingly, academia. In spite of its popularity, the term is still not clearly delineated and remains open to multiple interpretations. The current paper aims to provide more clarity with regard to what overtourism entails by placing the concept in a historical context and presenting results from a qualitative investigation among 80 stakeholders in 13 European cities. Results highlight that overtourism describes an issue that is multidimensional and complex. Not only are the issues caused by tourism and nontourism stakeholders, but they should also be viewed in the context of wider societal and city developments. The article concludes by arguing that while the debate on overtourism has drawn attention again to the old problem of managing negative tourism impacts, it is not well conceptualized. Seven overtourism myths are identified that may inhibit a well-rounded understanding of the concept. To further a contextualized understanding of overtourism, the paper calls for researchers from other disciplines to engage with the topic to come to new insights.

This paper introduces the Special Issue on slum tourism with a reflection on the state of the art on this new area of tourism research. After a review of the literature we discuss the breadth of research that was presented at the conference ‘Destination Slum’, the first international conference on slum tourism. Identifying various dimensions, as well as similarities and differences, in slum tourism in different parts of the world, we contest that slum tourism has evolved from being practised at only a limited number of places into a truly global phenomenon which now is performed on five continents. Equally the variety of services and ways in which tourists visit the slums has increased. The widening scope and diversity of slum tourism is clearly reflected in the variety of papers presented at the conference and in this Special Issue. Whilst academic discussion on the theme is evolving rapidly, slum tourism is still a relatively young area of research. Most papers at the conference and, indeed, most slum tourism research as a whole appears to remain focused on understanding issues of representation, often concentrating on a reflection of slum tourists rather than tourism. Aspects, such as the position of local people, remain underexposed as well as empirical work on the actual practice of slum tourism. To address these issues, we set out a research agenda in the final part of the article with potential avenues for future research to further the knowledge on slum tourism.

This article provides a view on the state-of-the-art literature on slum tourism. It points to the rapid growth of slum tourism research in recent years and highlights the main avenues that research has thus far explored in areas such as slum tourism history, slum tourist subjectivity, resident perspectives, slum tourism operations, economics, and mobilities. With the advent of slum tourism the relationship of poverty and tourism has changed. Tourism is no longer only a means to fight poverty, but poverty is an attraction of tourism. This has consequences for the relationship of slum tourism to other forms of tourism where poverty functions as an attraction, like volunteer or developmental tourism. The article identifies research gaps as well as avenues for further research.

This paper seeks to highlight underlying issues of the tourism system that have led to tourism extremes of too much or too little tourism. Five phases are recognized that reflect different ways of dealing with too much tourism over time, after which the impact of a sudden lack of tourism is investigated in light of future renewal processes. This discussion highlights the remarkable capacity of the tourism industry to adjust to rapidly changing circumstances and crises, even when these cause anguish to individuals and within societies at large. The paper thus seeks to contextualize the current discussions regarding the transformation of tourism post COVID-19. It highlights the complexity of changing a tourism that multiple stakeholders depend on or have grown accustomed to. To come to a more balanced tourism, it is necessary to not only come up with alternative visions and strategies, but also to engage with the political economy nature of tourism development. A future research agenda should therefore also discuss facets of entangled power, social exclusion, inequalities and class differences to come to new reference points of what actually constitutes a more inclusive tourism success.

The journal Sustainability has previously published special issues on sustainable tourism and on sustainable cities (both in 2014). This special issue presents recent insights from combining the two research topics. There is some convergence with respect to core challenges that sustainable urban tourism is facing. Firstly, relating to social sustainable development, there is the tension between the quality of life for residents in different ways and the development of cities to benefit the tourism industry. Secondly, relating to environmental sustainable development, there is the tension between residents and their desire for good local environmental standards and visiting tourists that create a number of over-tourism related local environmental problems. Thirdly, there are the challenges that so far have received less attention, but obviously are expected to become crucial in the years to come: The double climate change provides risks to cities from a changing climate and from more ambitious climate policies to come.

Tourism growth, particularly in cities, is coming under increased scrutiny. However, even often visited cities appear to find it difficult to agree upon a strategy to limit tourism growth. The current paper investigates this issue by looking at the extent to which different stakeholders’ perspectives on tourism development align. Q-sort methodology is employed to find the main worldviews and the extent to which they are shared by stakeholders in similar roles (e.g. policymakers, industry, resident). Results point to the existence of five different worldviews, which differ in the extent to which tourism growth is desirable or problematic and whether resident participation is advantageous or counterproductive. Stakeholders have highly different worldviews, even those with similar roles, which may help explain the difficulty to change the tourism growth paradigm as they limit opportunities for generating new consensus-based collective solutions. If we accept that tourism development strategies are driven and informed at least in part by individual worldviews, it may be impossible to make ‘objective’ policy choices. Instead, it might be more useful to explore possibilities to allow stakeholders to express their worldviews to better understand what sustainable tourism development entails for different people at different places and moments in time.
