Abstract
Tourism has been booming in Svalbard and has almost returned to pre-pandemic levels. At the same time, the island is a hotspot of rapid and cascading climate and environmental changes, which are already placing natural and social systems under stress. There is more precipitation, less sea ice, and glaciers are shrinking at an increasing rate. Presently, sweeping legislative changes are underway in Svalbard that hold the potential to change the scope and conditions of tourism in multiple ways. Drawing on a review of literature presenting recent projections for climate and environmental change and interviews with tourism actors (n=25), this article outlines how climate and environmental changes are currently impacting nature-based tourism actors in the archipelago and discusses opportunities and barriers for their adaptation to current and projected changes. We define impacts in three broad categories: increased vulnerability of ecosystems; climate risks to tourism; and climate change benefits to tourism. We find that tourism actors have a high adaptive capacity to said changes, taking advantage of increased access due to shrinking ice in the fjords and extending the summer season into the autumn months due to higher temperatures. Avalanches and other natural hazard risks are increasing, causing a higher frequency of disruptions to organized tours and excursions. This article contributes to ongoing discussions about how the tourism industry and residents will be impacted by the cascading and cumulative effects of climatic and environmental changes on Svalbard.
Introduction
Tourism continues to boom in Svalbard and has almost returned to pre-pandemic levels. Simultaneously, the archipelago is faced with rapid and cascading climate and environmental changes that are placing natural and social systems under stress. The tourism sector in Svalbard relies on a diverse set of contributions from these systems, such as sea ice, permafrost, flora, and fauna, as well as infrastructure, all of which are directly or indirectly affected by climate change (Hovelsrud et al., ; AMAP, ). The tourism industry plays a vital role in ensuring a viable and vibrant community on Svalbard and in Longyearbyen. On the one hand, the industry provides important income to the local community, contributing both to employment and community development (e.g., new restaurants, shops, and other meeting spaces). On the other hand, the impacts of climate change, for example, increased avalanches and other natural hazards, are disrupting organized tours and cause risk to infrastructure and the built environment (Meyer, ; Sokolickova et al., ). The rapidly increasing marine-based tourism (Port of Longyearbyen, ) creates a dilemma regarding how the tourism industry should balance the provision of services, such as boating and cruising, with protecting the archipelago (Olsen et al., ; Hovelsrud et al., ). Sweeping legislative changes that hold the potential to change the scope and conditions of tourism on Svalbard in multiple ways are also currently underway (Hovelsrud et al., ). The tourism industry in Svalbard is thus faced with walking a tightrope where it must cope with rapid and cascading climatic and environmental changes while balancing the competing demands of economic growth and environmental governance (Hovelsrud et al., ).
Spatial and temporal reduction in sea ice cover has expanded the navigation season and area of operation, which has enabled a demand-driven growth in cruise traffic (Stocker et al., ). The sea ice season in the Barents Sea–Svalbard region is getting shorter, and recent studies project that the Barents Sea will be totally ice free by the 2040s (Bennett et al., ). The changing climate is thus widely believed to enable continued expansion of Arctic marine-based tourism and to lead to opportunity-based adaptation to climate change (Dawson et al., ). A recent estimate on shipping development around Svalbard indicates that the level of activities will continue to increase toward 2040 (Olsen et al., ). In July 2022, a French cruise ship company reached 90 degrees north with tourists for the first time. Until then, only Russian icebreakers had brought tourists to the North Pole. Cruise ship tourism to the North Pole is thus already a reality (Humpert, ; Kubny, ). At the same time, climate change is causing what can best be described as an emergency response crisis in Longyearbyen (Hovelsrud et al., ). An avalanche destroyed 11 houses and killed two persons in 2015. Subsequent avalanche risk assessment led to the relocation of several residential buildings. Major investments have also been made in landslide protection and flood protection, as well as in reinforcing roads and buildings to withstand thawing permafrost (Meyer, ). There is also a concern that climate change is making ecosystems and wildlife more vulnerable to negative impacts from human activities (Hovelsrud et al., ; Norwegian Environment Agency, ). Increased human traffic in the far North may introduce new species and potentially harmful microorganisms to the ecosystem (e.g., through ballast water; Goldsmit et al., ). Further, the ongoing Atlantification of the marine ecosystem changes the trophic interactions, with increased predation pressure on many Arctic key species, such as polar cod and large-sized Arctic copepods (Misund et al., ).
Ongoing changes in Svalbard tourism create socio-economic opportunities for the tourism industry and tourism-related services and organizations, as well as for local communities (Olsen et al., ). These include a shift from seasonal to year-round tourism, new markets and tourism segments, a change from land-based toward marine-based tourism, and increasingly promoting Longyearbyen as a tourism destination and not only for transit (Olsen et al., ; Sokolickova et al., ). These opportunities are increasingly balanced against climate change impacts, sustainability requirements, governance, and regulations (Hovelsrud et al., ).
Tourism regulation on Svalbard addresses the protection of nature in the context of tourism growth (MoJPS, ) by limiting the area for access and passage, setting requirements for organized outdoor activities, and developing regulation instruments, such as environmental taxes (Hovelsrud et al., ). The Svalbard Environmental Protection Act (SEPA) stipulates that environmental concerns shall trump economic interests in case of conflict and that large areas will remain unchanged for the purposes of research and monitoring (MoJPS, ). Meanwhile, Svalbard's flora, fauna, and cultural remains shall be sustained without influence from human activities, preserving opportunities to experience nature undisturbed by motorized activities, even in the vicinity of settlements (MoJPS, ). In September 2021, the Norwegian government began a public consultation process1 on suggested amendments to the SEPA and associated regulations.2 The proposed changes signal increased state control (Sokolickova et al., ), and the process resulted in significant reactions from Longyearbyen business operators, the local population, and other actors (Haugli, ). In January 2023, the Norwegian Environment Agency published their suggested amendments, which maintained the major points in the hearing document, including suggestions to limit the number of passengers on tourism vessels ships to 200 and reduce the number of sites allowed for visitors. The decision by the Norwegian government is awaited with both eagerness and apprehension, depending on one's point of view.
Currently, there is limited knowledge about how the tourism industry in Svalbard is impacted by the cascading and cumulative effects of climatic and environmental changes. This article combines a literature review on the state of knowledge about such changes with interviews with tourism actors about their perceptions of changes in the climate and the environment, as well as their adaptations to such changes. It also discusses potential impacts of the projected changes in climate and ecosystems on the tourism industry.
Key concepts
Climate change impacts a tourism destination in multiple ways, and several frameworks have been developed to capture different aspects of this. The analytical framework of this article is based on a synthesis of the climate risk assessment framework for tourism, as outlined by Scott et al. (), and the concept of climate risks developed by the Intergovernmental Panel on Climate Change (IPCC, ). We thus define climate risk, in line with the IPCC (), as composed of the following elements: hazard, exposure, and vulnerability, where the latter is again a function of sensitivity and adaptive capacity. This study focuses on the hazard element within this framework and the sensitivity aspect of the vulnerability element (i.e., the extent to which the tourism actors are susceptible to harm from the impacts of climate change).
We will also discuss the adaptive actions and adaptive capacity of tourism actors in Svalbard. Adaptive capacity is the ability to cope with external stresses and shocks (Smit and Pilifosova, ). It is not directly observable, but it can be inferred through different determinants (e.g., Smit and Pilifosova, ) or proxies (e.g., Dannevig et al., ). These include human, social, and financial capital, infrastructure, and institutions (Dannevig et al., ). We recognize that tourist actors are part of a tourism system, which again are nested within the wider socio-environmental system (Scott et al., ; Becken, ) (see Figure 1), but we do not set out to deliver a system-wide assessment of climate risks. Instead, we focus on how changes in climate drive changes that impact the tourism system and produce (a) increased vulnerability of ecosystems, (b) climate risks to tourism, and (c) climate change benefits to tourism (see Figure 1). A nature-based tourism system, such as the one we find on Svalbard, is reliant on the natural environment and its weather, climate, and ecosystems. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has introduced the concept of “nature's contributions to people” (NCP) to address shortcomings with the concept of “ecosystem services” and to capture the various valuations of nature that exist in different cultures and for different purposes (Pascual et al., ). We paraphrase the IPBES and call the NCPs on which the Svalbard tourism system is dependent “nature's contributions to tourism” (NCT). These include landscape features, such as fjords, valleys, and mountains, as well as the sea ice, glaciers, snow, and wildlife that enrich the tourism experience. This article focuses on how the tourism system is impacted by climate change's effects on these NCTs.

Methods
This article reports on a project that aimed to deliver climate services to the tourism industry in Svalbard, employing a co-production approach that combined a top-down, expert review of projected changes in climate, cryosphere, and ecosystems with a bottom-up approach to perceived climate risks and adaptations. A co-production of knowledge approach means that users of knowledge are involved in the knowledge production process in order to ensure actionable results (e.g., Dilling and Lemos,
In the results section, we first present projected climate changes and their impacts on natural systems according to four impact categories outlined below, and we then present results from semi-structured interviews on observed changes, impacts, and adaptations. Finally, we discuss the adaptive actions and strategies and what these reveal about the adaptive capacity of the tourism system.
Approach to literature review
Based on the above-mentioned input meeting, the authors defined four categories of climate change impacts relevant for tourism and divided responsibility for literature review within these categories. The categories were: (1) temperature and precipitation change; (2) coastal and sea ice change; (3) natural hazards; and (4) glacier change. The point of departure for the review was existing climate change and climate change impact assessment reports, such as the “Climate in Svalbard 2100” report by the Norwegian Climate Service Center (Hanssen-Bauer et al.,
Semi-structured interviews
Our analysis draws on qualitative field research carried out in Svalbard between 2021–2022, during which 25 semi-structured interviews were carried out with key actors from the tourism industry. Semi-structured interviews allowed for the flexibility to explore topics brought up by interviewees that might not have emerged in more formal settings (Maxwell,
Nature-based tourism in Svalbard
The Svalbard Treaty of 1920 grants Norway sovereignty on Svalbard, but citizens of the any of the 46 signatory countries can establish industries or live on Svalbard. The population in Svalbard therefore consist of multiple nationalities, settled in Svalbard's two main settlements: Longyerbyen with 2,500 inhabitants and the Russian settlement Barentsburg with 300 inhabitants. Svalbard's tourism development has been framed by the Norwegian Svalbard policy and the Treaty, which, among other objectives, aims to preserve nature while simultaneously maintaining Norwegian communities in the archipelago (Kaltenborn et al.,

Since the restructuring of a state-owned coal company, Store Norske Spitsbergen Kulkompani, at the end of the 1980s and the collapse of the Soviet Union in 1991, tourism has been an important industry for Svalbard communities and their socio-economic development (Olsen et al.,

Svalbard has been a cruise destination since the end of the 19th century, but the scope was historically limited. Nowadays, passenger vessels operating in Svalbard waters comprise overseas, expedition, and day cruise vessels, as well as pleasure crafts. The expedition vessels use Longyearbyen as a turning harbor, while remote Svalbard locations present the main attraction for the expedition cruise tourists. For the overseas cruise vessels, Svalbard (usually Longyearbyen) is one of many destinations along their itinerary; hence, they spend only a short period of time on Svalbard (usually a few hours, e.g., Olsen et al.,
Results
We have defined four categories of climate and ecosystem change with relevance for tourism, which are each treated in their own subsection. For each category, we first present a synopsis from the literature review of climate and ecosystem change projections, followed up by a subsection on observed impacts and adaptation based on interviews.
Changes in temperature and precipitation
Over the last 100 years, temperatures have increased by an average rate of 0.3 degrees Celsius per decade, with the largest increase observed in winter temperatures (Hanssen-Bauer et al.,
Figure 3

Annual mean temperature change for the Svalbard land area given as deviation from the reference period 1971–2000. The points and black curve show historical values. The blue and purple area show high and low model projections for RCP 4.5, and the colored lines represent the medians (figure from Hanssen-Bauer et al.,
The projected temperature increase will have massive effects on ecosystems. The growing season (successive days per year with temperatures above 5 degrees Celsius) in the Isfjorden area is projected to increase from between 2 and 55 days to 128 days by 2100 (see Hanssen-Bauer et al.,
Precipitation is also increasing, and in Longyearbyen, precipitation has increased by over 20% since 1971. By 2100, annual precipitation is projected to increase by ~40% (RCP 4.5) to ~60% (RCP 8.5) (model medians) compared to the 1971–2000 baseline (Figure 4). Projections show that episodes of rain during winter in the Longyearbyen area will triple (Norski klimaservicesenter,

The purple and red area show model projections for RCPs 4.5 and 8.5, and the colored lines represent the medians (figure from Hanssen-Bauer et al.,
The snow season has decreased by 20 days from 1958 to 2017, but the amount of snow that has fallen has increased in line with the increased precipitation. Climate projections estimate a further increase in snow, but a rapid shortening of the snow season (Norsk Klimaservicesenter 2021). Figure 5 shows a large difference between projections of snow days between the RCP 4.5 and RCP 8.5 scenarios for the period 2071–2100. With the RCP 8.5 scenario, there will be no snow during winter in the coastal areas around much of the islands.

Impact and adaptation
The increased temperature is already noticeable in Svalbard, with consequences for tourism operators: the summer season offerings, particularly day trips with boats, are extending much longer into the autumn than even 10 years ago, according to a tour operator and guide who was interviewed: “I find it very nice that we can prolong the season in the autumn, (…) but not so happy about starting the boating season in March-April, because that will degrade our winter products” (Guide 14). While autumn on Svalbard used to be short, higher temperatures and less sea ice allows for boat trips and hiking trips during September. The reduced daylight is more of a limiting factor during the winter months. With the projected changes, it is likely that this development will continue if there is demand for these types of tourism products.
The average Svalbard guide does not stay for many years, so a given guide may not have experienced changes in weather and climate themselves. However, some of our informants had lived on Svalbard for more than 15 years, some even longer. They noted the increasing temperatures, particularly the increased frequency of warm weather spells in winter, something that “never” happened before. “I have seen huge changes (...) it is more precipitation, both snow and rain. It rarely rained before. And quite little snow; it is an Arctic desert here (...) Three years ago, we had rain in April, first in 40 years” (Guide 14).
Another reoccurring theme among the old-timers is the interannual variability in conditions: “What I really notice and pay attention to is how much the temperatures vary between years (...) the only things that's for sure is that the coming winter won't be like the previous one” (Guide 7). This guide also believed that Svalbard was headed for a colder climate after having experienced many years with steady temperature increases. Some also found that the weather was more unpredictable. Before, winter weather was more stable, but there are now more frequent episodes of wind and precipitation. As one guide noted, “I find it harder to plan trips now” (Guide 5). One of the dogsledders we interviewed stated that sufficient snow cover for dog sledding was tending to arrive later and later. “When we got started here, we had a dog sledding trip on November 1st. And now in recent years, at the worst, we haven't been out until after Christmas” (Guide 1). Guides and operators also recognized that they would be impacted by a shorter winter season for snowmobile trips. In general, the informants believed that a shorter winter season was something they would be able to adapt to.
Coastal and sea ice changes
Marine and coastal ecosystems
In the last two decades, boreal species have become more prominent in Svalbard waters, and this “Atlantification” of the Svalbard marine ecosystem is particularly prevalent along West Spitsbergen (e.g., Berge et al.,
These glacial fjord bays are also important habitats for sea ice-dependent seals, since calving glaciers produce ice bergs on which the seals can rest. These chunks of glacier ice accumulate drifting snow and make it possible for ringed seals to make protective snow caves for their pups (Lydersen et al.,
Sea ice
Prior to 2005, sea ice formed in many of the fjords in Western Spitsbergen, but after 2005, changes in weather patterns combined with slight changes in sea water densities have resulted in more frequent and larger intrusions of warm Atlantic or modified Atlantic water into the fjords (Nilsen et al.,
Figure 6

Reduction in land-fast sea ice for the period 1973–2000 compared to the period 2014–2018 in Svalbard (A) and specifically for Isfjorden (B) (from Søreide et al.,
Impact and adaptation
Interviews with tourism operators reveal a nuanced perspective on how climate change affects sea ice, nature, and wildlife. One interviewee observed less sea ice in the fjords as having negative consequences for biology and for travel and attributed this to increased temperatures (Guide 10). One of the experienced “Svalbardians” we interviewed noted the changes in sea ice between 1998 and 2021: “In the late 1990s and early 2000s, one could drive snowmobiles on solid ice across the Isfjorden, and all the way to Hornsund—the southernmost tip of Spitsbergen” (Guide 15). In other words, it was possible to travel on sea ice along the coast of the western part of Spitsbergen. “Now we have more ice on land than at sea” (Guide 15). The lack of sea ice in the fjords is a major cause for concern for the winter tourism operators in Longyearbyen. The ringed seal (Pusa hispida) depends on sea ice for breeding, molting, and resting. It builds snow lairs on the land-fast ice to give birth to pups, and with less sea ice and land-fast ice, the ringed seal's habitat is significantly reduced. Where there are ringed seals, we find polar bears, which attract tourists. But with reduced ice, to protect wildlife, it is prohibited to travel on the fjords with snowmobiles or break the ice with boats. These fjords used to be popular tourism destinations. The tourism operators are critical of the regulations that prohibit visits to these spectacular fjords.
For the summer tour operators, less sea ice makes it easier to operate in Svalbard. Although cruise vessels have been operating in Svalbard waters since the end of the 19th century (Viken et al.,
The increase in ship and boat traffic comes with water pollution, invasive species distribution, marine litter, and more underwater noise, which disturbs marine mammals and species (Olsen et al.,
Natural hazards
Climate change is increasing the risk of natural hazards on Svalbard. Specifically, climate change is projected to accelerate permafrost thaw in coastal and low-altitude areas, exacerbate the risk of avalanches and landslides, and increase precipitation, which will lead to increased flood risk (Hanssen-Bauer et al.,
Permafrost thaw
Svalbard faces significant changes related to permafrost thaw. Monitoring of permafrost thermal states provides clear evidence of warming permafrost in Svalbard, and near-surface permafrost in coastal and low altitude areas is projected to thaw before the end of the century (Hanssen-Bauer et al.,
Avalanches
Projected increases in temperature and precipitation (in the form of both snow and rain), coupled with accelerating permafrost thaw, will likely increase the frequency of all types of avalanches and landslides in Svalbard in the coming decades (Hanssen-Bauer et al.,
Increased human activity on Svalbard affects people's exposure to natural hazards, such as avalanches and floods. The population and tourism have grown considerably in recent years and, consequently, the number of people involved in backcountry activities has substantially increased. Human-triggered slab avalanches seem to cause the most fatalities among recreational backcountry skiers and snowmobilers, while naturally triggered avalanches are the main threat to infrastructure, transport routes, and residential areas (Hanssen-Bauer et al.,

Floods
While flood estimates for Svalbard are highly uncertain, changes in the frequency and magnitude of floods are strongly linked to changes in precipitation, snow storage, and glacier regimes. On Svalbard, increased precipitation will likely lead to increased rain floods and increased combined snowmelt, glacier melt, and rain floods. In turn, increases in rain, glacier melt, and river flows will increase erosion and sediment transport (Hanssen-Bauer et al.,
In regions where the annual maximum snow storage is expected to decrease, snowmelt floods will become smaller. For the high-emission scenario toward the end of the century, the glacier area and volume in several catchments will be reduced to the extent that the contribution from glacier meltwater to floods will be negligible (Hanssen-Bauer et al.,
Landslides and rockfalls
Increased air temperature and permafrost thawing, combined with increasing frequency of extreme precipitation events, will lead to more active slope processes and significantly greater instability in mountain slopes, leading to an overall rise in landslide activity in Svalbard (Hanssen-Bauer et al.,
Impacts and adaptations
Svalbard is experiencing the impacts of climate change at a rate that far surpasses mainland Norway, and the concomitant risk of natural hazards will likely have significant consequences for human activity in the archipelago. While more research on the relevance of natural hazards and climate change for tourism is needed, several recent studies shed light on some of the societal impacts of climate change on Svalbard and in Longyearbyen (Tvinnereim et al.,
Increased avalanche activity, for example, poses a growing risk to human life in Svalbard, both in the backcountry and in residential areas. Longyearbyen experienced two major avalanche events in December 2015 and February 2017. In 2015, two people lost their lives when a large slab avalanche from the ridge of Sukkertoppen destroyed ten houses in Longyearbyen. The 2017 avalanche damaged several buildings, but there were no fatalities (Hestnes et al.,
Tourism operators we interviewed mentioned the increased risk of natural hazards stemming from climate change as a growing concern. One respondent explained: “What we have worked on the most in relation to climate change here in the valley [Longyeardalen] are the natural hazards that are starting to emerge. We have areas around the valley that we won't be able to inhabit in the future. And that will also apply to hotels and rentals” (Guide 4). When asked whether increased avalanche risk impacted their operations, the respondent replied: “It significantly impacts our work. And we have noticed that closures due to avalanche danger are now much more frequent than when we started working here” (Guide 4). Another guide (Guide 8) explained that they had changed their tours to go to areas without much risk of avalanches.
Concerns regarding natural hazards are also reflected in the literature, which concludes that large parts of Longyearbyen will need to be either upgraded or relocated due to the increased risk of natural hazards, such as landslides and avalanches, thawing permafrost, and flooding (Hovelsrud et al.,
Glacial changes
The glaciers of Svalbard are rapidly losing mass, and a recent survey found a 1.5-meter decline of the Longyear glacier, measured during the summer of 2022 (Geyman et al.,
Impacts and adaptation
The shrinking glaciers are one of the key indicators of climate change in Svalbard. Guides that have lived for some time in Longyearbyen note how much the Larsbreen glacier, which lies close to Longyearbyen, has shrunk (Guide 15). One consequence of the shortened snowmobile and ski season is that snowmobilers and skiers must traverse glaciers instead of traveling along the coast or in the valleys, where there is a lack of snow. This comes with its own set of risks, which we will outline below. Warmer winters also include more frequently occurring episodes of rainfall, which can cause rivers to open, blocking important transportation routes in the valleys.
According to guides, the retreat of glaciers damages and disrupts major tourism transportation routes in central Spitsbergen used for snowmobiles, skiers, dogsledders (mushers), and, to some extent, hikers (e.g., Figure 7). The shortening of the snow season and the loss of sea ice are forcing a relocation of snowmobile routes toward the inner parts of Spitsbergen, which includes long stretches of glacier and ice cap crossings and higher-altitude terrain. This exposes snowmobilers to crevasses and more challenging weather conditions.
Barriers and opportunities for adaptation and adaptive capacity
As its tourism industry continues to boom, Svalbard is faced with rapid and cascading climate and environmental changes that are placing natural and social systems under stress. There is more precipitation, less sea ice, and glaciers are retreating at an increasing rate (Hanssen-Bauer et al.,
Climate change is also heightening the risk of natural hazards, which will likely have significant consequences for all human activity on Svalbard. Climate change is projected to accelerate permafrost thaw, exacerbate the risk of avalanches and landslides, and increase precipitation, which will lead to increased flood risk. Increased avalanche risk, for example, is likely to cause more frequent closures of major inland snowmobile routes, such as the one between Barentsburg and Longyearbyen (see Figure 7). In addition to hampering snowmobile and ski tourism, heightened avalanche risk affects people's psychosocial health and quality of life (Hovelsrud et al.,
Coping with risk that occurs during nature-based tourism activities requires skills and knowledge from the guides and well-established safety procedures from the tour operator. All tourist operators that were interviewed pride themselves in employing highly qualified guides, and all guides that were interviewed had completed relevant formal guide-qualification schemes. The tour operators also have internal health and safety procedures that they claim to follow rigorously. The guides' competence and the operator's safety procedures constitute human and institutional capital that all contribute to adaptive capacity in the tourism system (e.g., Dannevig et al.,
While the authors initially believed that the ultimate test of adaptive capacity would be the COVID-19 pandemic, the situation turned out to be more complex. Tour operators and guides that were Norwegian or from the European Economic Area (EEA) treaty countries (EU + Norway, Iceland, and Liechtenstein) enjoyed rather generous support measures that allowed them to endure the pandemic.3 Non-EEA guides and operators, on the other hand, of whom there were many before the pandemic, were forced to leave Svalbard when their income disappeared. The economic support provided to the Norwegian and EEA guides and operators meant that they were not forced to adapt to endure and survive the pandemic. One of the operators did however concede that he was “poor at writing applications for support” (Guide 1) and had had to change his business model, taking more assignments from the local high school instead of doing trips with tourists. Overall, the majority of our informants report that they have not made major long-term changes to their operations and products as a response to the pandemic, though some have used it to adjust products or develop new ones.
Conclusion
In this article, we have examined opportunities and challenges that are emerging for the tourism industry on Svalbard in the context of climate change. Drawing on a literature review of recent projections for climate and environmental change, as well as interviews with tourism actors, we found that while tourism actors have strong adaptive capacity, they are increasingly constrained by higher risk of natural hazards and potentially new regulations aimed at curbing tourism growth (Hovelsrud et al.,
Until now, the impacts of climate change have been of greater benefit than hindrance to tourism in Svalbard, in that they have allowed for a new tourism season with ship and boat traffic in the spring. However, the rapid and cascading changes projected in the coming decades are likely to be disruptive, particularly in terms of increased risk of natural hazards. There is therefore an urgent need to continue to study how the tourism industry in Svalbard is impacted by the cascading and cumulative effects of climatic and environmental changes.
