The water demand is increasing across all sectors, driven by intensive agriculture, overexploitation and urbanization, tourism, and industrial development. This trend is set to intensify in the context of climate variability, with an anticipated rise in the frequency and intensity of prolonged dry periods. As a result, conventional water resources, including surface and groundwater, are facing significant pressure and cannot meet the growing water needs. In contrast, unconventional (UWR) or non-conventional water resources, such as treated wastewater, salinized water, and rainwater harvesting are emerging as valuable and strategic resources and will play a pivotal role in the new era. Therefore, it is evident that the management of water resources must also include UWR to address the issue of water scarcity, with the ultimate goal of achieving a sustainable water future. This review aims to provide an overview of the currently and potentially available UWR in Greece. In addition to current trends and prospects, this study examines the utilization of unconventional resources in ancient Greek civilizations. The main conclusion is that in the context of the circular economy and the implementation of the Sustainable Development Goals (SDGs), the use of unconventional water resources is crucial for facing the problems that are emerging.

As unconventional building structures, container houses are now widely used in urban tourism to create characteristic buildings. Nowadays, natural gas accidents occur frequently in cities and towns; however, the development of laws and influencing factors of natural gas accidents in container buildings have rarely been studied. In this paper, a natural gas explosion test was carried out in an ordinary container house, and a numerical simulation was carried out according to the test results. The influence of methane proportion, ignition position, pressure-relief area, and pressure-relief intensity on the explosion load was analyzed. Research shows that natural gas will gather from top to bottom during the process of leakage and diffusion, and vertical stratification will occur. The most unfavorable working condition is 9.5% methane. Using the roof of the container house as a pressure-relief panel can effectively control the influence range of natural gas explosion accidents and help reduce accident losses. It is suggested that the stacking of container buildings should be reduced as much as possible, and the roof strength should be weakened to ensure structural safety. The research results have certain reference values for the disaster prevention and reduction design of urban characteristic buildings. Full article

In recent years, there has been a surge in interest towards innovative methods of landscape presentation across various tourism sectors, including natural heritage. Geotourism exemplifies this trend, emerging as a distinct form of tourism primarily centered on inanimate elements of nature, accentuating the aesthetic value of landscapes. Presently, geotourism serves as a platform for showcasing landscape along with its historical narrative, contemporary attributes, and, inherently, its evolutionary trajectory. This paper delves into novel avenues within geotourism, introducing the concept of nostalgic geotourism. This concept involves the portrayal of geological heritage through the lens of historical inquiry. The authors employ a multidimensional analysis to forge a robust theoretical framework underpinning the emergence of this unconventional form of tourism dedicated to landscape presentation. Additionally, the paper furnishes a case study conducted in the High Tatras region, featuring a 19th-century guided tour (lecture) on non-living nature. Through this illustration, the theoretical construct of nostalgic geotourism is applied to the locale. This heralds a fresh dimension of tourism reminiscent of traditional nostalgia-based tourism, with a pronounced cultural focus. The innovative concept fosters an increased interest in exploring geological heritage and natural landscapes, while emphasizing their sentimental value. Full article

The dilemma of choosing between conventional energy and renewable energy sources is a topic of discussion in various economic and social sectors. This problem is not only a matter of the country’s energy security but is also an important element of sustainable development that affects the functioning of future generations. The analysis of this process must cover all aspects of operation, with particular emphasis on tourism, including ski resorts. The aim of the work is to assess the current state of ski infrastructure in terms of the possibility of using green energy to power these types of devices, with an indication of the profitability of implementing this project. This analysis will cover the types of renewable energy sources and how they are used in winter sports resorts around the world, whilst additionally focusing on the energy structure of Poland and the European Union, as well as on energy transformation plans in Poland. An important aspect of this analysis is to understand the barriers to the development of the unconventional energy sector and the ski resorts themselves. The impact of ski resorts on the natural environment was also examined. When analyzing the profitability of introducing green energy to power ski slopes, the costs of traditional energy sources in a Polish ski resort were analyzed. The benefits of introducing green energy were indicated by comparing SWOT analyses of the Polish coal sector with renewable energy sources. In the economic context, the profitability of the proposed renewable energy installation was presented, using the NPV, IRR and payback period methods. The analysis of the cost structure of traditional energy sources allowed for the identification of a potential investment in renewable energy technologies, showing the share of electricity costs in the structure of energy carriers used on the ski slope. As a result, the profitability of the installation project was indicated as photovoltaic with specific power and parameters. Although the presented considerations refer to the realities and legal regulations applicable in one of the selected European Union countries—Poland, a country where energy from photovoltaic panels is developing the fastest among all renewable energy sectors in Europe—these considerations can be used in practice to indicate further directions and development prospects for other regions of the world. At the same time, the content of the considerations creates the basis for further development of research on these processes in order to popularize Poland’s energy policy. Full article

Oil shale is a kind of unconventional energy resource with abundant reserves, but its exploitation has a continuous negative impact on the environment, which has hindered the research and exploitation of oil shale under the international environmental consensus on issues such as climate change. Therefore, more attention should be paid to environmental problems as the side effect of oil shale exploitation. With the combination of field research, literature collection, and tracking survey, the oil shale open-pit exploitation and management process in Maoming, Guangdong, China, has been investigated, and its development and transformation model has been subsequently refined and summarized. The research results show that Maoming oil shale open-pit mine area has gone through four main stages: pre-exploitation stage, large-scale utilization stage, restoration stage, and green development stage. Through the management of mine pit treatment, vegetation restoration, ecological park construction, and tourism resource development, the abandoned open-pit mine has been transformed into an ecological park combining ecosystem, tourism, and cultural resources. In this process, this area has achieved the transformation from rough resource extraction to environment-friendly sustainable growth in its development mode. As a successful case of open-pit mine management in the world, the ecological restoration experience in Maoming can function as a reference for the smooth development and transformation of other oil shale mines in developing countries.

The last two years, the period of the pandemic, have brought a significant change in the tourism of Hungary, which has been developing unbroken until then. The year 2019 broke all the peaks that were interrupted by the pandemic. This particularly affected our spa towns of international significance, including the examined settlements, Hévíz and Zalakaros. The aim of the study is to show what changes have taken place in the development of the number of visitors in the cities that have been based mainly on foreign traffic until then, what territorial reorganization has taken place in terms of sending areas, and what new target groups with modified attitude have emerged. In this study, we analyzed in detail the databases of the National Tourist Data Center, which has been operating since July 2019, and the monthly database of the Hungarian Central Statistical Office. The special, so-called unconventional tourism is carried out on the one hand by the methodology of statistical data collection and on the other hand by the explored tourism behavior. According to our results, it is clear that due to the domestic traffic, a completely new target group (age group and status) appeared in the two spa towns, their sending areas affected the metropolitan suburban zones, and the target group was high-status, younger guests. In our opinion, this offers a new opportunity for spa towns to generate more sustainable, future-oriented guests with a focus on local values, creating a new supply structure and image, as well as messages.

The adoption of renewable energy (RE) is a promising business strategy for bed and breakfasts (B&Bs) to mitigate climate change while maintaining a competitive edge. However, there is still a lack of analytical studies to determine an optimal RE mix for tourism accommodations. This study thus proposes a practical approach to enable all B&Bs to make optimal RE decisions for their facility. A mixed-integer programming (MIP) model is developed and tested in a case study. The model successfully identifies an optimal hybrid energy system for two scenarios, the base case that generates 116,942 kWh of electricity annually at the cost of USD 21,499, and the unconventional technology case that generates 114,474 kWh of electricity annually at the cost of USD 24,670. Compared to purchasing all the required electricity from the power grid, both scenarios can save more than 26 tons of CO₂e/year. The analysis provides valuable information for B&Bs to initiate a smooth energy transition with affordable costs. This study considers various energy components, including hybrid RE, batteries, the power grid, self-sufficiency targets, and various RE technologies. Therefore, B&Bs can choose a preferred self-sufficiency target where RE satisfies a specific portion of the energy demands and the power grid satisfies the rest. The model can also evaluate the tradeoff between investing in RE technologies and purchasing larger batteries. These findings will assist B&Bs in accelerating the adoption of RE globally.

Prior to the COVID-19 pandemic, tourism had permeated all spaces of experience, reaching nearly every country, region, community, and corner of the globe. In recent decades, the meanings, implications, and roles of tourism have also expanded significantly. This article focuses on unconventional tourism mobilities, including same-day visits, which are an important but often neglected part of the tourism system, constantly challenging both scholars and tourism industry stakeholders. Unconventional tourism is an umbrella term that covers most kinds of unregistered or unaccounted tourist mobilities, some of which might not appear to be ‘tourism’ but should be in certain localities and under certain conditions. Given the growth of unregistered tourist flows and unaccounted leisure (or utilitarian) mobilities, there is a need in tourism studies to apply innovative research methods and to reconceptualize the meanings of tourism in different geographical and social contexts. It is expected that people’s desire to travel in the post-pandemic era will educe new spatial and temporal travel experiences and behaviours in which unconventional tourisms will play an important role. To better understand this phenomenon and to evaluate the development of new approaches to travel and behavioural spatialities, new ways of thinking, new theoretical constructs, and new methodologies are needed. This article seeks to explore certain hidden or invisible tourism mobilities, focusing on the geographical patterns, processes, and hidden aspects of unconventional tourism. Full article

The spread of autonomous vehicles (AVs) could fundamentally change tourism-related mobility in the near future. However, the empirical research on tourism impacts is still very limited. This research aims to systematize the expected tourism impacts of AVs and to explore how experts in different fields of tourism view the technological innovation ahead. The opinions of tourism experts (n = 21) involved in the research were analyzed using the Q methodology. Statements (n = 40) were formulated in topics derived from the literature. Based on the analysis, we distinguished four groups of opinions. An optimistic, technology-oriented group of experts suggested that AV-based sightseeing may emerge as a prominent unconventional service. An accessibility-focused group of experts predicting slow progress stressed that the spread of AVs could improve access to infrastructurally advanced destinations. A mobility-service-oriented group considered that the use of AVs is becoming conventional in terms of mobility, but its appearance remains unconventional for other tourism services. Due to the potential negative effects, a skeptical group of experts believes that AVs will not become conventional in tourism. The value of the research is the creation of groups based on tourism experts’ attitudes, which can help prepare strategic tourism decisions in the future. Full article

Health security measures have become increasingly important in tourism, as there is a heightened need to rebuild the trust of tourists in destinations and tourism services. Innovative product development might help respond to the emerging health-related needs of tourists. We address the lack of the application of Designcommunication (DIS:CO)-based approaches in the field of tourism, present a process for the theoretical development of a smart device, and explore its applications. Combining the results of the qualitative inquiry and applying DIS:CO in research and development, the concept of 4S—traveling Safe, Secure, Smart, and Sustainable—emerges in a socio-cultural and economic context, supporting the foundation of the material realisation of the product. As a result, the 4S concept presents how customised, continual feedback on the health condition of the user before and during a trip, and notifications about possible health risks in different tourist areas, might facilitate the process of trust-building. Although data on unconventional tourists is not included in tourism statistics, the designed product can assist in gathering information about them, too. With the permission of users, the built-in functions of the designed product can be used to detect their position and direction of movement. The product also helps monitor the health of tourists by providing up-to-date data on infection levels to tourism service providers. In its passive mode, as a souvenir, the device strengthens travel desire. Full article

With the advent of the knowledge economy, universities have increasingly important roles in cities. However, some universities and cities are still fragmented, and popular science tourism is one way to solve this. The purposes and destinations of popular science tourism differ from those of traditional tourism. Consequently, their resources have a high development value for ecological and human resources. However, research on popular science tourism in China is still in its infancy. Here, we studied popular science tourism from a geographical perspective, selecting scale capacity, environmental level, resource level, location, and service conditions as factors to construct a judgment matrix to calculate the weights of indicators at various levels. Analytic hierarchy was used to build a popular science tourism evaluation system for Guangzhou University Town as a case study and the suitability of each tourist destination in the university town was evaluated. The results show that west Guangzhou University Town is more suitable for popular science tourism than the east, which possesses more value for popular science tourism development. Finally, we give recommendations for developing popular science tourism in Guangzhou University Town. Full article

This paper addresses the phenomenon of overtourism in Budapest from multiple perspectives, starting with an overview that uses information collected from news, media, and academic tourism literature. Further, the phenomenon of overtourism is addressed quantitatively using different indicators, including tourism density and intensity. According to these indicators, the center of Budapest (formed by districts I, V, VI, VII, VIII, and IX) has been strongly affected by the presence of tourists, while districts physically far from the center have been less affected. This fact suggests the heterogeneity of the city in terms of overtourism. The number one catalyst of the negative impacts of foreign visitors’ behavior is party tourism (‘ruin pub’ tourism), which involves an unconventional use of the Hungarian capital. Finally, using an unconventional optimization method called fuzzy linear programming, we attempt to explore the challenging problem of identifying the optimal number of tourists for the city. The results of the study have important theoretical, methodological, and practical implications. On the theoretical side, we offer a comprehensive understanding of the phenomenon of overtourism in Budapest. Methodologically, the integrated approach in terms of data gathering and unconventional analytical methodologies (comprised of a case study analysis, the assessment of effective indicators for measuring the discussed phenomenon, and the demonstration of the sustainable number of visitors) represents a novel perspective about the extent of overtourism in Budapest. On the practical side, our findings provide valuable guidance for policymakers to help mitigate the problem of overtourism in the city. With regard to future research, we suggest extending and updating the results presented in this study to develop more sustainable tourism strategies. Full article

Many Korean universities grant undergraduate and graduate school degrees in part on coursework, theses, and dissertations that explore Taekwondo through various academic lenses in Taekwondo Studies programs, yet only a few individuals have traveled to the Korean Peninsula to study Taekwondo academically. Traveling internationally to earn a university degree in a martial art can be considered extreme martial arts tourism. This multidisciplinary study explores the motivations of non-Koreans who have studied Taekwondo academically in Korea as well as their aspirations after graduation. The study utilized a combination of autoethnographic techniques and interviews with individuals who have given up years of their lives, thousands of dollars, their home cultures, languages, and food, and their families to travel to a foreign university in order to study Taekwondo. Twelve participants were identified that met the selection criteria, but eight responded to the interview requests. The nine participants, including the author, came from a wide assortment of backgrounds, but all shared a passion for Taekwondo; now, most participants (n = 5) have jobs within the Taekwondo industry, including two professors in separate Departments of Taekwondo. This study’s findings elucidate why non-Koreans study Taekwondo academically and thereby offer suggestions on how to improve this educational market. Full article

Throughout the Middle East and the Islamic world, political and religious leaders are being pulled into sharpening debates over rival approaches to reforming the Hajj. For at least two decades, Hajj controversies have deepened with rising death tolls among the pilgrims and with soaring complaints about corruption and incompetence against pilgrimage managers in Saudi Arabia and dozens of other countries. Demands for Hajj reform are reaching new peaks after Saudi officials recently revealed stunning details of the scope and magnitude of pilgrim fatalities during the last 14 years. The Saudi data leave little doubt that the quality of care for Hajjis varies enormously depending on several key factors which policy makers and religious leaders must address with greater honesty and determination. Year in and year out, the most vulnerable pilgrim populations are poor people, women, and children from across Africa and Asia as well as foreign workers, refugees, and illegal migrants living in Saudi Arabia. Most of the current proposals for Hajj reform ignore these high-risk groups. Saudi planners focus on promoting year-round pilgrimage to boost tourism revenues and high-end infrastructure. In most other countries, government-run Hajj agencies are busy cutting market-sharing deals with private business cartels and their political patrons. The combined effect of these policies is to weaken what remains of already inadequate regulations that are vital to the protection of all Hajjis. Meanwhile, support is also growing for more sweeping proposals to reimagine and reinvent the Hajj instead of fine-tuning the status quo. Some of these reforms are particularly likely to test the ingenuity and influence of leaders from all backgrounds because they challenge longstanding custom. A few of the most unconventional suggestions include lengthening the Hajj season to several months as well as linking the Hajj to pilgrimages and festivals of other world religions throughout the year.
