Over the past decade, research on the impacts of climate change on immovable cultural heritage (ICH) in the polar regions (Arctic and Antarctica) has slowly increased. This article offers a systematic review and synthesis of the publications about climate change impacts on the diverse ICH and climate change adaptation in the polar regions. Gray literature was not included in the study. Arctic countries like Sweden, Finland, Iceland, and Russia, and their associated research organizations, are under-represented in this literature when compared with the USA, Canada, Denmark, and Norway. More than half of the analyzed literature is published in the last 3 years (2019, 2020, and 2021) with a focus on coastal erosion and ICH degradation (cryospheric hazards). ICH is at risk from biological degradation, coastal erosion, debris flow, and thaw slumping. Nearly half of the studies report on the need for climate change adaptation planning and implementation for ICH. This study shows that advances in research on climate change impacts and adaptation responses are needed to improve decision- and policy-maker capacity to support effective adaptation policies and to contribute to the achievement of SDGs in polar regions. The polar regions' vulnerable landscapes and ICH sites can be used to communicate a larger message about the climate change challenges and adaptation measures.

Climate change threatens archaeological sites and cultural landscapes globally. While to date, awareness and action around cultural heritage and climate change adaptation planning has focused on Europe and North America, in this article, the authors address adaptation policy and measures for heritage sites in low- and middle-income countries. Using a review of national adaptation plans, expert survey and five case studies, results show the varied climate change adaptation responses across four continents, their strengths and weaknesses, and the barriers to be addressed to ensure better integration of cultural heritage in climate change adaptation planning.@en

Climate change poses a threat to heritage globally. Decolonial approaches to climate change–heritage research and practice can begin to address systemic inequities, recognize the breadth of heritage and strengthen adaptation action globally.@en

Flooding causes serious impacts on the old town of Venice, its residents, and its cultural heritage. Despite this existence-defining condition, limited scientific knowledge on flood risk of the old town of Venice is available to support decisions to mitigate existing and future flood impacts. Therefore, this study proposes a risk assessment framework to provide a methodical and flexible instrument for decision-making for flood risk management in Venice. We first use a state-of-the-art hydrodynamic urban model to identify the hazard characteristics inside the city of Venice. Exposure, vulnerability, and corresponding damage are then modeled by a multi-parametric, micro-scale damage model which is adapted to the specific context of Venice with its dense urban structure and high risk awareness. Furthermore, a set of individual protection scenarios are implemented to account for possible variability in flood preparedness of the residents. This developed risk assessment framework was tested for the flood event of 12 November 2019 and proved able to reproduce flood characteristics and resulting damage well. A scenario analysis based on a meteorological event like 12 November 2019 was conducted to derive flood damage estimates for the year 2060 for a set of sea level rise scenarios in combination with a (partially) functioning storm surge barrier, the Modulo Sperimentale Elettromeccanico (MOSE). The analysis suggests that a functioning MOSE barrier could prevent flood damage for the considered storm event and sea level scenarios almost entirely. A partially closed MOSE barrier (open Lido inlet) could reduce the damage by up to 34 % for optimistic sea level rise prognoses. However, damage could be 10 % to 600 % higher in 2060 compared to 2019 for a partial closure of the storm surge barrier, depending on different levels of individual protection.@en

Research focusing on climate change and cultural heritage informs heritage management and policy. Fatorić and Seekamp assessed this field up to 2015, highlighting the need for periodic reassessment of the field given the observed growth and research that documents how cultural heritage contributes to climate change mitigation and adaptation. Five years on, this systematic review reflects on the state of the art by evaluating 165 publications (2016–2020) about cultural heritage and climate change. We find the field continues to grow, and remains rich in disciplinary and methodological diversity, but predominantly represents research in and about Europe. The number of publications about integrating cultural heritage into adaptation and mitigation are increasing but remain relatively few compared to those about physical impacts on individual buildings or sites. The impact of climate change on intangible heritage has rarely been the sole focus of recent research. Although researchers are increasingly situating their research in a wider context of opportunities and barriers, vague timescales, and unspecific references to changes in the natural environment are additional limitations. This review also identified a lack of international collaboration, highlighting the urgent need for global cooperation and knowledge exchange on climate change and cultural heritage.

This chapter focuses on mainland coastal towns that have populations of between 10,000 and 50,000 inhabitants. Through six case studies, the chapter develops an understanding of the characteristics that shape each of the communities. By exploring the climate change hazards each of the case studies are experiencing now and forecast into the future, the physical and ecological profile and the human development condition, a view of the climate impacts for each is shaped. The six case study areas include towns that are large enough to be a regional centre, down to much less organised and resourced communities that are at a more subsistence level of development. The case studies include communities that range from tropical storm areas to more temperate climatic areas. Adaptation strategies for each case study are observed, drawing out the similarities and the differences. Insights and lessons learnt show that the bottom-up inclusion of all communities in shaping the adaptation approach is crucial, together with alignment of policy between governments from national to local. Also crucial is the resourcing of local councils which sit on the front line of many adaptation initiatives. The role of universities and other research organisations to provide data, skills training and a toolbox of methodologies to those in the front line leadership roles. An important insight is the collaborative opportunity for universities, communities and agencies to draw out the innovative adaptation strategies that can inform other coastal communities from the smallest village to the largest city.

Climate change is increasingly being recognized as a threat to natural and cultural World Heritage (WH) sites worldwide. Through its interaction with other stressors, climate change accelerates existing risks while also creating new obstacles. A more considerable focus is needed in both research and practice to explore proactive measures for combatting this issue (e.g., mitigation and actions prior to impacts occurring). World Heritage values in climate change decision-making processes is an important factor in this regard. This paper explores a discussion of climate change within the WH monitoring system. It offers an overview of practice based on the extent to which WH properties (natural, mixed and cultural) implement landscape-based approaches alongside the conservation and management of their outstanding universal value within the context of climate uncertainty and environmental change. Landscape approaches are gaining importance in the WH conservation system, where they aim to provide concepts and tools for managing heritage toward sustainable practices. This research analyses the state of conservation reports and provides an overview of practice across time, categories and geographical regions. Based on a theoretical approach, empirical analyses identify four landscape principles that are increasingly shaping the debate around climate change issues in WH properties. Although these are highly relevant to advancing much-needed collaboration among scientific disciplines and governance sectors, we argue that further understanding is required on the transformational process of heritage values, as well as on the nature–culture relationship, in order to underpin heritage as a source for local resilience and climate mitigation. @en

Cultural heritage-specific research is scarce within the climate change literature and climate change policy documents, challenging climate adaptation efforts to minimize adverse impacts on cultural heritage. Engaging and assessing diverse stakeholders' values and integrating those with evidence-based knowledge is critical for timely, effective and transparent preservation and climate adaptation of coastal cultural heritage. This study assessed technical experts' and community groups' opinions about the importance of value-based prioritization considerations to provide more immediate guidance adaptation planning and decision making. The findings from four separate elicitation surveys demonstrated substantial consistency in value-based climate adaptation prioritization preferences for one type of vulnerable cultural heritage: historic buildings in coastal zones in the United States. In particular, the samples of cultural heritage professionals and members of community groups consistently rated spatial importance, uniqueness, and scientific value of historic buildings as very important considerations for climate adaptation prioritization decision-making. Also, consistently evaluated but of relatively low importance were considerations related to the cost of preservation and adaptation treatments, including previous investments. Few statistically significant differences were found among our samples in their perceptions of importance. These findings provide initial guidance to cultural heritage managers, particularly those with scarce financial resources to allocate for adapting coastal historic buildings, and demonstrate the need for continued development of approaches that provide rapid assessment of coastal heritage stakeholders' adaptation priorities.

Cultural heritage provides a wide range of economic, socio-cultural and environmental benefits for current and future generations. Globally, scientific evidence shows that climate change is adversely affecting diverse tangible and intangible cultural heritage [1; 2]. Yet, in the Netherlands, there is a need for a greater understanding of the cultural heritage vulnerability to climate change hazards. Understanding the vulnerability of cultural heritage to climate change hazards is of paramount importance to inform and guide proactive climate change adaptation planning and to reduce the potential damage or loss of heritage [3; 4; 5]. The aim of this study is to evaluate and visualise the potential exposure of nationally significant cultural heritage (national monuments or Rijksmonumenten) to multiple climate change hazards in the Netherlands. The climate change hazards assessed in this study include coastal and river flooding, urban pluvial flooding, drought and heat. The assessment is presented in a series of tables, graphs and maps for ease of use. Importantly, the presented exposure of monuments to climate change hazards is not a measure of actual risk or impact, but the first scan of different levels of exposure of monuments to climate change hazards using a scientific database of Climate Impact Atlas.@en

The Gullah Geechee community of the south-eastern United States endures today as a minority group with a significant cultural heritage. However, little research has been conducted to explore this community’s resilience in the face of climate change and other environmental impacts. The database Web of Science was searched and 109 publications on the Gullah Geechee community were identified. Using quantitative and qualitative methods, we analyzed the publications to identify patterns and primary research themes related to the Gullah Geechee community’s resilience. Findings revealed that Gullah Geechee‘s cultural heritage is vulnerable to climatic and societal changes, but can also be a source for enhancing community resilience and promoting more sustainable community-led heritage and tourism developments. A framework is proposed for building community resilience in the context of minority and/or marginalized communities (e.g., Gullah Geechee). This study highlights the urgent need to not only better understand and incorporate a community’s economic dimensions and losses in various decision- and policy-making processes but also their cultural and social dimensions and losses. This systematic analysis can help inform both heritage preservation and community-led tourism practices and policies related to the Gullah Geechee community, as well as help direct new research efforts focusing on minority and/or marginalized community resilience.@en

Climate change is currently impacting cultural heritage globally. Despite advances in the understanding of the relationship between climate change impacts and cultural heritage, there are significant barriers that hamper adaptation of cultural heritage to current and projected climate risks. This paper aims to advance the empirical understanding of barriers to adapting cultural heritage to climate-related impacts in the Netherlands by identifying different barriers, their interdependencies, and possible strategies to overcome these barriers. Using a web-based questionnaire with 57 experts, we find that the most frequently reported barriers are a lack of climate change adaptation policy for cultural heritage, and lack of climate vulnerability and risk assessments for diverse cultural heritage types. Our study finds that barriers are perceived to be interdependent and conjointly constrain adapting cultural heritage to climate change. Six actionable strategies are identified to navigate these barriers.@en

Climate change impacts on diverse cultural heritage is gaining scholarly and policy attention, yet little research has been conducted on how can diverse cultural heritage inform decisionmakers and policymakers in achieving climate change actions (i.e., climate change adaptation and mitigation). For this study, we conducted semi-structured interviews with Dutch cultural heritage and environmental or climate change experts (n = 52) and participant observations across the Netherlands to explore the importance of cultural heritage benefits and their relation to climate change actions. We also explored the perceptions of cultural heritage management over time, including the influence of climate policy on heritage practice in the Netherlands. Our findings show that experts perceived a multiplicity of heritage benefits as important in supporting and informing present and future climate change actions. The most salient benefits were informational benefits where diverse cultural heritage is perceived as an important source of knowledge about past societal, economic and environmental developments and changes. Further, heritage management was perceived as constantly changing over time, reflecting the transformative nature of diverse heritage types. Experts agreed that climate policy has already influenced cultural heritage practice in the Netherlands. Lastly, the interrelationships between heritage benefits and management were identified and characterised. This study informs both cultural heritage and climate change research agendas and helps leverage diverse cultural heritage into climate change adaptation and mitigation policies.@en

Climate adaptation is a process for minimizing the risks of damage or loss to coastal archaeological sites. Yet, adaptation requires identifying and prioritizing among the diverse aspects of a site’s significance, as not all sites can be simultaneously adapted due to financial and human capital constraints. Developing a measurement framework that can ascertain the relative significance between sites necessitates the collaboration of multiple perspectives, including experts who set policy and on-the-ground managers who must translate policy into practice while accounting for the management preferences of associated communities. This paper explores if a values-based process enables co-production of knowledge related to the significance of archeological sites. Specifically, this paper examines the influences of a workshop—conducted with diverse archaeological experts working for the U.S. National Park Service—on knowledge co-production and documents the extent of changes in experts’ opinions using a pre–post survey design. Findings suggest that the values-based approach applied during the workshop can have a positive impact on knowledge co-production among experts. Changes were found in experts’ perceptions of the importance of various considerations influencing archaeological site prioritization, as well as of the extent to which uncertainties challenge archaeological preservation. This paper presents novel findings about the importance of knowledge co-production in relation to coastal archaeological site preservation and climate adaptation in the U.S. Prioritization considerations and challenges of various uncertainties assessed in this study can provide valuable insights for progress in climate change policy for cultural heritage both in the U.S and globally.@en

Climate change poses great challenges for cultural resource management, particularly in coastal areas. Cultural resources, such as historic buildings, in coastal areas are vulnerable to climate impacts including inundation, deterioration, and destruction from sea-level rise and storm-related flooding and erosion. However, research that assesses the trade-offs between actions for protecting vulnerable and valuable cultural resources under budgetary constraints is limited. This study focused on developing a decision support model for managing historic buildings at Cape Lookout National Seashore. We designed the Optimal Preservation Decision Support (OptiPres) model to: (a) identify optimal, annual adaptation actions for historic buildings across a 30-year planning horizon, (b) quantify trade-offs between different actions and the timing of adaptation actions under constrained budgets, and (c) estimate the effectiveness of budget allocations on the resource value of historic buildings. Our analysis of the model suggests that: (1) funding allocation thresholds may exist for national parks to maintain the historical significance and use potential of historic buildings under climate change, (2) the quantitative assessment of trade-offs among alternative adaptation actions provides generalizable guidance for decision makers about the dynamics of their managed system, and (3) the OptiPres model can identify cost-efficient approaches to allocate funding to maintain the historical value of buildings vulnerable to the effects of climate change. Therefore, the OptiPres model, while not designed as a prescriptive decision tool, allows managers to understand the consequences of proposed adaptation actions. The OptiPres model can guide park managers to make cost-effective climate adaptation decisions for historic buildings more transparently and robustly.
