Hiorthhamn is an abandoned Norwegian coal mining settlement with a loading dock and a lot of industrial infrastructure left in the coastal zone. In this study, changes in the position of 1.3 km of the Hiorthhamn shoreline, which affect cultural heritage, is described for a time-period spanning 92 years (1927–2019). The shoreline positions were established based on a map (1927), orthophotos (2009) and a topographic survey with differential Global Positioning System (GPS) (summer 2019). Detailed geomorphological and surface sediment mapping was conducted to form a framework for understanding shoreline-landscape interaction. The shoreline was divided into three sectors to calculate the erosion/stability/accretion rates by using the DSAS (Digital Shoreline Analysis System) extension of ArcGIS. The DSAS analysis showed very high erosion in Sector 1, while Sectors 2 and 3 showed moderate accretion and moderate erosion, respectively. Sector 1 is geologically composed of easily erodible sorted beach sediments and protected remains from the mining industry such as wrecks of heavy machines, loading carts, wagons and rusty tracks that are directly exposed to coastal erosion. The all-sector average shoreline erosion rate (EPR parameter) for the 92 years period was −0.21 m/year. The high shoreline erosion rates in Sector 1, together with the high potential damage to cultural heritage, supports the urgent need of continued coastal monitoring and sustainable management of cultural heritage in Hiorthhamn.

In line with the Paris Agreement, Norway aims for an up to 55% reduction in greenhouse gas (GHG) emissions by 2030 compared to 1990 levels and to be a low-emission society by 2050. Given that 85–90% of today’s buildings are expected to still be in use in 2050, refurbishment and adaptive reuse of existing buildings can help in achieving the environmental goals. The aim of this work is to provide a holistic picture of refurbishment and adaptive reuse of existing buildings, including buildings with heritage values, seen from a life cycle perspective. The methods applied are a literature review of LCA studies and experiences from quantitative case study analysis of selected Norwegian case studies. The findings show that extending the service life of existing buildings by refurbishment and adaptive reuse has significant possibilities in reducing GHG emissions, keeping cultural heritage values, and saving scarce raw material resources. The findings show limited LCA studies, uncertainties in existing LCA studies due to variations in case-specific refurbishment or intervention measures, and a lack of transparent and harmonized background data and methodological choices. In conclusion, performing a holistic study covering the whole LCA and including socio-cultural values and economic aspects will enable supporting an argument to assert the sustainability of existing buildings.

Biological deterioration is a significant threat to wooden cultural heritage in polar regions. Based on a comprehensive review of previous and current research, we provide an overview of current knowledge of wood-decaying fungi and fungal decay in historic wooden structures in Antarctica and the High Arctic. Most available research focuses on degradation mechanisms, providing data on microbial biodiversity and factors influencing deterioration of the historic polar heritage. Less is reported on decay rates and consequences for cultural heritage, such as the type and severity of damage, causes, repair, and conservation methods. The effects of climate change improve conditions for fungal decay, and thus more severe damage must be expected. Consequently, further research and development should concentrate on these challenges to promote conservation of polar cultural heritage and sustainable heritage management. Greater cooperation between researchers across disciplines in polar regions may be of key importance to improve insights and treatments for polar wooden heritage.

This article reports findings from two research projects that aimed to understand the vulnerabilities of cultural heritage sites in Svalbard and investigated factors that influence tourism-induced pressures and site degradation. It draws upon fieldwork conducted at ten selected historic locations, including interviews with tourists and guides, consultations with regional and central cultural heritage management authorities, on-site observations, and condition assessments. The primary goal was to explore indicators rendering cultural heritage sites susceptible to the impacts of tourism and human visitors. These indicators were common denominators and encompassed the sites’ physical state/degree of decay, legibility, accessibility, and quantity and quality of objects at the sites. This article seeks to enhance the understanding of these sites’ vulnerabilities and provide insights for effective heritage site management and sustainable tourism development. The principal findings highlight key factors contributing to cultural heritage sites’ vulnerability. These factors encompass intensity and frequency of visitor traffic, suboptimal visitor management strategies, tourists’ limited awareness of proper site behaviour and conservation practices, and restricted resources for site maintenance and protection. These findings can guide policymakers, site managers, and tourism stakeholders in formulating strategies to balance tourism promotion with site conservation, ensuring the long-term preservation of cultural heritage in this unique and vulnerable environment.

This paper emphasises on degradation of wood in cultural heritage structures at Svalbard. Nowhere else does global heating occur faster. Negative impacts of climate change will increase the strain on wooden structures and can daily be observed at Svalbard. The severe changes affect the degradation rate of wooden constructions, including cultural heritage. Certain microclimates, also in Polar areas, are favourable to fungal growth and decay. The probable enhancing effects climate change have on fungal degradation in wooden structures are however alarming. The paper displays findings of measurements from four different case study projects at Svalbard between 2009 and 2019. The results have been analysed separately, compiled and discussed in context, and towards relevant literature. We claim that impacts of climate change may not be generalized in order to predict effects in building materials. Further, that with extended knowledge on how climate change affects natural development of fungal decay, negative impacts may be reduced. Lessons learned from high Arctic areas might add longevity and sustainability to wooden cultural heritage constructions, also in different areas and environments. The paper is part of two of the authors' PhD work at the Norwegian University of Science and Technology.

The identification and preservation of cultural landscapes worthy of protection is a challenging task, as their significance is often not immediately apparent. Analyzing the process through which a site or landscape became a heritage site and understanding the historical context and the factors that contributed to its designation allows making informed decisions on the management and preservation of the site. To provide research-based knowledge, this paper aims to analyze the transformation of the degraded remains of the North Pole expedition bases of Andrée and Wellman in Virgohamna, Svalbard, into a protected historic landscape and the subsequent emergence of the site as a current popular tourist destination. Virgohamna serves as an illustrative case for examining the heritagization process of cultural heritage sites in Svalbard. This article adopts a multidisciplinary approach, drawing upon case studies, mapping and categorizing the historic and current landscape, the condition and vulnerability assessment of historic remains, behavior studies on visiting tourists and guides on-site, expert interviews, and document studies. The findings highlight the complex processes that have influenced the making of the cultural heritage landscape in Virgohamna, the enduring narrative associated with the site, and the need for continued efforts to ensure the preservation and dissemination of its historical significance. Analyzing the process through which Virgohamna has become a heritage site and understanding the historical context and the factors that have contributed to its designation as a heritage site has the potential to enhance comprehension regarding historical importance and heritage values. Furthermore, it might facilitate engaging stakeholders and formulating management approaches and provide insights for policy suggestions. The comprehensive examination serves as a foundation for responsible and sustainable heritage management, ensuring the preservation and promotion of Virgohamna’s cultural heritage for present and future generations.
