1. Introduction
Tourism research has long sought answers to what is and how to achieve sustainable tourism. The milestone progress includes three pillars of sustainable development and 17 United Nations (UN) sustainable development goals (SDGs). Then, in 2020, the tourism literature suddenly shifted heavily to the panic of the century that had taken over the world—COVID-19 and its effects. The latest update from Word Tourism Organization (UNWTO) in December 2020 stated: “the decline in the first ten months of 2020 represents 900 million fewer international tourist arrivals compared to the same period in 2019, and translates into a loss of US
$935 billion in export revenues from international tourism, more than 10 times the loss in 2009 under the impact of the global economic crisis” [
1]. Although UNWTO’s extended scenarios for 2021–2024 point to a rebound in international tourism by the second half of 2021, a return to 2019 levels in terms of international arrivals could take 2½ to 4 years [
1]. Given the impact of the pandemic on economic losses in countries, this shift is not surprising, but what specifically do tourism scholars write about the pandemic and its consequences for tourism? What new insights can the literature on COVID-19 provide to guide our practice in sustainable tourism?
Before answering these two questions, it is necessary to say something about views on what sustainable tourism is. Here we take as point of departure Saarinen (2013)’s typology of sustainable tourism, where he identifies three views. First, the view that sustainable tourism is about sustaining the business of tourism, i.e., giving priority to financial viability of the industry [
2]. An underlying assumption must be that a viable tourism industry is good for society at large, providing jobs and tax revenue to the state to provide services to its citizens. The second view gives priority to environmental concerns, like carrying capacity, to put limits to tourism [
2]. Even if concepts like carrying capacity are appealing, they have proven difficult to implement. Activities of tourism do not exist in a vacuum, but amidst other human activities, the effects of which become intertwined, so it is not easily possible to determine what environmental consequences come from what. The third view goes beyond the confines of the tourism industry when considering sustainability, and rather focuses on the places and people within which tourism takes place [
2], i.e., the local community. This third view is the only one which allows more substantial rethinking of what tourism can and should be, even to the extent that refraining from tourism altogether could be the better option in some instances [
2].
Then, why can the literature on COVID-19 guide us in the practice of sustainable tourism? On the one hand, voices have been heard arguing that as we deal with the effects of the pandemic, we run the risk of, but must not forget about, sustainability, as if the pandemic is not a sustainability issue in itself. The underlying assumption seems to be that companies (and societies) now must deal with economic recovery, and during such circumstances, they cannot afford to work with (expensive) sustainability solutions. Understanding the pandemic-induced challenges that have arisen and finding viable solutions to them can, however, be seen as working with sustainability. Whether a point of departure in the 17 UN sustainable development goals or the classic three pillars of sustainability (environmental, social, economic), it is clear that the pandemic has caused all sorts of unsustainable problems for tourism [
3]. From this perspective, dealing with the effects of the pandemic is not something different than dealing with sustainability, but part of it.
On the other hand, there are other ways to view the nature of the sustainability issue of the COVID-19 pandemic. Originating outside of discussions of tourism is a view of sustainability problems as wicked problems (like [
4,
5]), i.e., involving a high degree of uncertainty, limited knowledge about the future and consequences of actions, and that it is not possible to find a singular right answer that will solve the problem, but that these problems will always be with us and the best we can do is to continuously try to deal with them, in ways that will never be optimal. Resilience, adaptivity, flexibility, collaboration, and co-creation become relevant ways of working with sustainability challenges in this view. Dealing with the pandemic, like dealing with other sustainability challenges (such as climate warming), will not require exactly the same remedies, but the same kind, building resilience, adaptivity, flexibility, collaboration, and co-creation.
From these two ways of understanding sustainability, we suggest that the pandemic in fact can be seen as a sustainability challenge and that the literature on tourism and the pandemic may function as a “thermometer” of the way scholars view sustainability and tourism, and that exploring this literature gives us a space to reconsider our understanding of sustainable tourism. Therefore, it is important to understand the large number of publications on tourism and the pandemic not only because it helps us make sense of what is going on within tourism research in this turbulent time, but also because from this new literature we may learn valuable lessons on how scholars conceive of tourism and sustainability, its problems, and their resolutions more broadly, outside the particular context of a pandemic.
As a result, we conducted a literature review of the COVID-19 literature in tourism in 2020. A total of 87 articles, in 17 journals, from 4 databases were found and analyzed, with the purpose of exploring how current scholars perceive COVID-19 and tourism, in light of sustainability perspectives. What perspective one has on sustainable tourism within Saarinen (2013)’s typology or other, will determine what one sees as solutions to problems. In our analysis of the COVID-19 and tourism literature, we analyzed what kind of solutions scholars propose, i.e., in what way they possibly see the pandemic as a sustainability challenge or not, and what view of sustainable tourism they propose.
The outline of this article is as follows: the next section presents the method used in this study;
Section 3 and
Section 4 present the main findings based on content analysis and descriptive statistical analysis methods;
Section 5 comprehensively discusses these main findings, responding to “What to hope?”, “What is the challenge?”, and “Where is the turning point?” Finally,
Section 6 summarizes the main findings and states the limitations of this research are presented to invite further research.
2. Methodology
The purpose of this study is to identify the trends in COVID-19 and tourism literature. The literature on COVID-19 and tourism has proliferated in 2020, but a broad framework has not been mapped out to further develop and evaluate this emerging field of knowledge. A content analysis-based literature review is a good systematic review method “to map and assess the existing intellectual territory, and to specify a research question to develop the existing body of knowledge further”, according to Tranfield et al. [
6]. Tranfield et al. [
6] pointed out that this method aims to identify “key scientific contributions” and to reduce bias and “provide collective insight” to a field. Ref. [
7] also refers to it as “a systematic, explicit, and reproducible design for identifying, evaluating, and interpreting the existing body of recorded documents”. Ref. [
8] suggested this method as a structured and consistent procedure for generating reliable findings. Therefore, we used a content analysis-based literature review to conduct our study, according to the relevance of this method to our research purposes.
We utilized a six-stage refinement process suggested by Duan et al. [
9] to collect data (see
Figure 1). The six stages proposed by Durach et al. [
10] are define research question, set inclusion and exclusion criteria, determine searching databases, apply criteria, synthesize relevant literatures, and report findings. First, we put forward the research question, which is the earliest step that can be found in the introduction. In order to ensure reliability and representativeness of the results [
5], we defined a search string by querying a set of related keywords. The keywords and combinations identified and used in the online database search are “COVID-19” and “tourism”. Both COVID-19 and the tourism industry are prevalent and popular research fields, which means that they already have a large amount of research results. With this in mind, we set the two keywords of “COVID-19” and “tourism” as an “and” relationship instead of an “or” relationship, aiming to discover the intersection of these two research fields. Since COVID-19 only spread from Asia to the rest of the world in the spring of 2020, research related to COVID-19 only appeared in January 2020 and with some exceptions, the research hardly involves the publication of books. In order to ensure the academic quality and relevance of the data, we excluded sources other than journals. Taking into account the article’s audience area, popularity, article quality, and relevance to tourism research, we applied the defined search string to four mainstream publishers (Taylor & Francis, Wiley, Elsevier, and MDPI). The online databases of these four publishers were chosen because they are some of the most popular databases highly relevant to the tourism industry. The reason for using the publisher’s online database for search instead of other broader search engines such as Web of Science, Scopus, Google Scholar is to enable the selection of purely scientific articles. Focusing on purely scientific papers was to be achieved as the goal of the research. It was decided not to include industry reports and strategic documents of the development of cities [
8].
In the third step, we excluded duplicate papers and applied inclusion and exclusion criteria (see
Table 1). As of the end of data collection on 4 November 2020, we found a total of 87 journal articles with the keywords of “COVID-19” and “tourism” in the online databases of four major publishing houses (see
Table 2). Due to the emerging nature of COVID-19 research, we did not purposely limit the time of publication. The articles found were published from January 2020 to November 2020. The final 87 papers were classified and evaluated through content analysis, a systematic and objective research method that has been used to quantify phenomena, documents, or communicate [
8].
After content analysis, we employed summative and thematic content analyses to adequately address its objectives. Descriptive analysis is the first insight into all papers to provide basic information about the selected paper [
9]. The attributes of selected papers involved (i.e., time, region, methodology, and theories) were exported into Microsoft Excel to add some noteworthy supplementary information to the content analysis results. For example, statistics on the theories can reflect which theories are commonly applied at the intersection of COVID-19 and tourism. Microsoft Excel was utilized to rigorously execute the summative analysis, while thematic analysis was assisted by constant comparison. Content analysis usually focuses on the systematic collection, classification, analysis, and compilation of most non-digital data to make valid inferences, providing a comprehensive understanding of the phenomenon under investigation [
11]. As a result, content analysis is performed to extract, understand, organize, synthesize, and capture the relevant information contained in the selected account [
11]. The limitations of the method are discussed at the end of this study.
6. Conclusions
Due to the global pandemic of COVID-19, the world is facing an unprecedented global health, social, and economic emergency. As of the United Nations Statistics Division (UNSD) dynamic data on January 10, 2021, COVID-19 has caused 90,192,332 cases with 1,936,955 deaths. According to the World Tourism Organization update in December 2020, the confidence index of the World Travel Organization is still at a historically low level due to the slow control of the virus, travel restrictions, and low consumer confidence [
1]. First, the tourism industry is highly correlated with people’s conscious departure and leisure activity needs [
71]. As a result, the impact of the COVID-19 pandemic on the international tourism market is manifested in the health risks and psychological risks perceived by tourists, which leads to negative emotions towards the tourism industry and other tourists. The social distancing imposed by COVID-19 includes activities that reduce social contact and minimize tourism, which greatly affects people’s assessment of leisure and travel activities (such as nature-based tourism activities) and personal leisure services (such as spas and catering) [
62].The operating standards of COVID-19 force travel service providers to redesign products and services to innovate travel experiences, such as smelling alcohol or disinfected water instead of fragrance and machine services instead of labor [
62]. However, without compromising sociality and service quality, how far is the psychological distance between travel service employees and customers? Will the new service environment innovated by travel service providers for COVID-19 change the behavior and attitude of customers?
The drastic reduction in travel demand coupled with the government’s travel ban has had a serious impact on the profitability of travel service providers and in turn affected the tourism economy of countries. Given that the international travel ban affects more than 90% of the world’s population, as well as extensive restrictions on public gatherings and community movement, tourism basically ceased in March 2020 [
50]. Due to people’s fear of exposure to public air, strict quarantine measures, and lack of passengers, most domestic and international airlines were forced to cancel flights [
62]. Subsequently, the global tourism industry lost millions of jobs due to the cancellation of flights, events, and hotels [
62]. The role of the government and the informal sector is emphasized to provide financial and policy support to the affected tourism sector, and to restore domestic regional tourism and market confidence by supporting domestic and tourism, reviving marketing, and intergovernmental cooperation. Through these actions, the government seeks to strike a balance between maintaining the tourism economy and preventing unemployment and poverty, and at the same time responds to public health needs to prevent the collapse of the health system due to tourism [
27]. Therefore, it seems unsurprising that government as a leading subject was discovered by this study.
In the second half of 2020, with the gradual reversal of the pandemic and the launch of the COVID-19 vaccine, the World Tourism Organization has proposed a significant increase in passenger confidence and a significant lift in passenger travel restrictions in its update in December 2020 [
71]. The rebound is also the result of a large number of pent-up demand months after border closures and travel bans [
71]. Faced with the rapid depression of the tourism industry and tourists’ aversion to isolation, many countries that are highly dependent on the tourism economy (like Mallorca, Belize, and Cuba) have enacted “safe corridors” plans. In the “safe corridor” system, tourists can freely travel to countries in the safe corridor list without quarantine. However, does this really mean that the impact of COVID-19 is already under control?
Challenges and fears will always exist, due to the high degree of uncertainty in tourism, of whether there will be a new round of pandemic, and our limited understanding of the consequences of actions. The best we can do is to continuously sum up patterns from existing research to try to deal with them, in ways that will never be optimal. This research implies that dealing with the pandemic, like dealing with other sustainability challenges (such as climate warming), will not require exactly the same remedies, but the same kind, building resilience, adaptivity, flexibility, collaboration, and co-creation.
Considering the vast number of publications, increasing in fast pace, it is not easy to get an overview and an understanding of this. Scholars have evaluated the current world tourism industry from various angles and predicted the future of the global tourism industry after COVID-19. However, few researchers have completely integrated the COVID-19 and tourism literature and conducted content analysis to describe a complete framework.
This study filled this research gap by providing a systematic knowledge framework for the intersection of the two emerging research fields of COVID-19 and tourism. In this knowledge framework, this research described specific leading research aspects and discussed the guidance that COVID-19 research has brought to the tourism industry. A literature review of current research on COVID-19 and tourism is vital to piece together a complete answer, highlighting neglected areas of research and pointing out conclusions that have been repeatedly validated and emphasized. This study provided a comprehensive framework for current scholars’ perceptions of COVID-19 and tourism and framed the catastrophe of COVID-19 as a long-term sustainable learning opportunity to stimulate different thinking on this popular topic in society and academia.
This literature review of current research indicates some neglected but important research areas to invite future research. From the perspective of enterprise development, the current research focuses on the hotel and aviation industry, but we shall not ignore that the densely populated small and micro enterprises in tourist destinations have also suffered the same impact. What kind of crisis management model should they establish (including corporate resilience, employee management, financial portfolio, and business and management model innovation) and what are the costs and benefits of transformation? For communities, COVID-19 invites us to rethink and update the alternative social system (fairness, cooperation, and social responsibility) in the community and improve the community’s adaptability and innovation capabilities. For tourists, stereotypical tourists are usually spoilers and troublemakers, but this research showed that COVID-19 is changing tourists’ awareness of ethical tourism and sustainable consumption behavior. Can they travel to change others and how? Moreover, this research emphasizes two urgent aspects. We urgently need to establish a measurement standard to evaluate the performance of tourism stakeholders and establish a priority to ensure that other crises (such as climate warming, forest fires, species extinctions, etc.) are not ignored when mitigating and responding to the current pandemic. In this century, we seem to be lucky, because we have more technology and experience than ever before, so how should we use new technologies (such as information and communication technology) to create a smart and sustainable tourism future? The challenges of sustainable tourism transformation after COVID-19 are irreversible. How to overcome and mitigate these challenges requires solid empirical research involving various stakeholders, and the voices of residents and marginalized groups ought to always be given priority.
