Europe’s coastal, underwater, landscape and urban heritage is under threat. The growing climatic crisis and the related increase in the frequency and intensity of natural hazards alongside with anthropogenic pressure highlight the need to accelerate the incorporation of recent scientific and technological advancements to adapt current management practices to the changing climatic conditions. Reliable methods and systems to evaluate these threats are important for the efficient and proactive management of evolving risks for heritage. However, heritage assets are still managed following traditional procedures.
This session focuses on recent advances that contribute to the protection of heritage exposed to climatic, natural, and anthropogenic hazards and enhance the ability of heritage and connected communities to withstand and adapt to the era of extreme events. Potential contributions include, but are not limited, to the following:
•Models and data that advance the fundamental understanding of the effects of climate-change and natural hazards on heritage (e.g. complex phenomena like flow-soil-structure interaction)
•State-of-the-art techniques to identify, quantify and mitigate risks derived from natural, climatic, anthropogenic and biological hazards, including both single- and multi-hazard scenarios, at various types of heritage.
•Sensing solutions for monitoring risks based on in-situ, remote sensing, and terrestrial instruments.
•Monitoring ecosystems to assess risk and impact derived from expected and unexpected events.
•Early warning and decision support systems to optimize heritage management.
•Material characterization and advanced prediction capabilities for heritage deterioration.
•Participatory methods, immersive technologies and crowdsourcing applications to enhance the management of heritage and provide risk information (e.g., serious gaming, digital twins, mixed, virtual, and augmented reality).
•Post-disruption strategies to restore normal conditions to heritage sites, long-term strategic approaches for adaptation and policy tools for resilience and sustainability.
•Methods and tools to model, analyse, and improve the governance structures and management processes (e.g. network analysis or pathway approaches)
•Knowledge co-production and living lab approaches for risk and resilience assessments.

The session is co-organised by three Horizon Europe projects (THETIDA, TRIQUERTA, RescueME) funded under topic HORIZON-CL2-2022-HERITAGE-01-08.

Europe’s built heritage, cultural landscapes and sites are under immediate threat from the effects of climate change, including rising sea levels, prolonged droughts, floods, and strong storms. Acid rain and other environmental pollutants cause wear and defacement of monuments and historic buildings, while soil erosion accelerates the deterioration of underwater and coastal heritage sites. The effects of climate change also affect, directly or indirectly, indoor cultural heritage.

Horizon Europe, the 9th European Framework Programme for Research and Innovation (2021-2027), is a key instrument of the Union to tackle global challenges such as the impact of climate change and natural disasters on cultural assets, as well as to promote cooperation and the influence of research and innovation in the design, support, and implementation of EU policies. To further enhance efficiency and research collaboration, the European Commission (EC) clusters the consortia with similar research objectives during their lifecycle. The idea is to facilitate researchers to share insights and best practices, identify synergies for dissemination and communication actions, and propose integrated feedback recommendations to policy makers in the EC and beyond.

Since 2021, three calls for proposals have invited research teams to respond to the demands for more sustainable methods and technologies to restore monuments and works of art[i], the impact of climate change and natural hazards on cultural heritage[ii], and advanced technologies for remote monitoring in the field[iii]. The eleven projects selected for the EU funding have been encouraged to form the Green Cluster on Cultural Heritage.

Within the Green Cluster, the ‘’Climate Effects’’ Team, currently composed of four active EU projects (THETIDA, RescueME, TRIQUERTA, STECCI), has an overarching aim to address the urgent need to protect monuments, historic buildings, and sites from the diverse impacts of climatic risks, natural and anthropogenic hazards. This is expected to contribute to the conservation and protection of Europe’s heritage by exploiting cutting-edge remote monitoring technologies and modelling tools for multi-hazard risk understanding and better preparedness.

Research within the Green Cluster is complemented by other consortia that develop sustainable methodologies, materials and techniques for the preservation and restoration of art objects and explore the use of advanced and sophisticated technologies for more accurate, targeted, and reliable remote monitoring purposes.

The impact of the scientific research is furthermore amplified by the active involvement of Artificial Intelligence tools, a wide range of community groups, stakeholders, and participants covering the full spectrum of ongoing research activities. This includes participatory and inclusive approaches, such as citizen science and participatory Living Lab methodologies.

The overall goal of the EC is to support transdisciplinary joint efforts of researchers to develop sustainable preservation and adaptation plans, and to bring community involvement and inclusiveness to the forefront of large collaborative research projects funded by the EU. The long-term outcome will be the creation of a sustainable cultural heritage research ecosystem.

Cultural heritage (CH) sites are frequently situated in coastal areas that experience landslide activity, potentially influenced by climatic effects. A growing number of studies have directed their attention toward investigating mitigation strategies for CH sites impacted by landslides. Nevertheless, there is a paucity of quantitative studies dedicated to elucidating the relationships between coastal landslide activity and climate-related factors. Specifically, the comprehensive understanding of the extent to which both preparatory and triggering climate-related factors contribute to slope instabilities remains incomplete. This knowledge gap is particularly pronounced in the case of waves and wind, whose impact is extensively examined in coastal engineering applications.
The Punta Eolo sea-cliff (Ventotene island, Italy) is here analyzed since it is frequently affected by rock-falls and topples that are threatening the vulnerable remnants of the roman archaeological site of Villa Giulia. This latter is one of the pilot sites selected in the framework of the H2020 TRIQUETRA European project, aimed to proposing a methodological framework for mitigating climate-related natural hazards affecting cultural heritage.
To account for the action of sea waves on a sea cliff, a preliminary attempt was made to couple hydrodynamic modeling of sea-related actions with stability analysis managed through limit-equilibrium and stress-strain approaches.  For the hydrodynamic modelling a mesh-based computational fluid dynamics (CFD) method, that had been validated previously for extreme wave impact on coastal structures both in 2D and 3D conditions, was utilized. The results of the hydrodynamic analysis (e.g., stress field applied on the cliff by waves impact) were then used as input data for the stability analysis. The slope stability conditions of Punta Eolo's sea cliff were evaluated for a rock-toppling mechanism; following that, slope stability analyses were carried out under static and pseudo-static conditions. The analysis considered both seismic action and static water pressure within the joint sets. In a subsequent phase of investigation, the sea-wave action was incorporated as a force accountable for an elastic rebound sensu Hutchinson (1988). Through hydrodynamic modeling, the maximum computed force exerted by sea waves against the cliff was converted into a pseudo-static coefficient. This latter served as input for the factor of safety (FOS) calculation.
The quantitative analysis has brought to light the potential occurrence of instability conditions in specific rock blocks when the hydrostatic backpressure resulting from the filling of rock cracks is coupled with a pseudo-static force, originating from the elastic rebound induced by the impact of sea waves. This scenario represents the most frequently encountered action at the examined cliff of Punta Eolo.
Finally, the project of the ongoing installation of a tailor-designed monitoring system in Punta Eolo is presented. This system aims to characterize the physical attributes of sea-related preparatory and triggering factors affecting the cliff, and to assess the deformative response of the cliff itself under the influence of periodic thermal and hydrodynamic stressors.

A methodology is presented for downscaling the wind projections of Euro-CORDEX in order to derive temporally and spatially correlated region-wide wind fields that can be used for assessing the wind risk for cultural heritage sites. The coarse spatial and temporal resolutions of the Euro-CORDEX projections prohibit their use as a direct input for such purposes, especially for cultural heritage assets that are spatially distributed within the Euro-CORDEX grid and dynamically respond differently to wind. To improve the temporal resolution of the Euro-CORDEX data, we leverage machine learning tools and weather station measurements, aiming to generate composite “Frankenstein” days at the locations of the weather stations that comprise 144 jigsaw pieces of actually measured 10min wind time-series that are matched together to form a continuous daily record. The “Frankenstein” days are expanded spatially to all locations where critical assets can be found by employing spatially distributed wind fields that are computed via high-fidelity computational fluid dynamics simulations and provide contemporaneous wind values at all locations of interest. This process allows generating “Frankenstein” days and wind fields with a temporal resolution of 10min and spatial resolution that allows assessing the wind risk for spatially distributed assets. As a case study, the Euro-CORDEX wind projections are downscaled for the cultural heritage village of Metsovo that is found at the Western part of Greece. Most of the buildings within this village are made of stone masonry and tiled roofs and are vulnerable to extreme wind actions as wind can cause damages e.g., on the tiled roofs thus making the buildings vulnerable to rainfall, or even lead to their partial or complete failure. Thus, the Frankenstein days and wind fields are employed for assessing the wind risk for the cultural heritage buildings of Metsovo both on an event-basis and in the long-term.

Cultural Heritage (CH) monuments are often subject to various environmental threats, with climate change (CC) exacerbating their vulnerability. These historical sites, valuable for their cultural and archaeological significance, face increasing risks of deterioration due to land deformation, flooding, acid rain, erosion, and man-made hazards like illegal excavations. Such threats not only endanger the structural integrity of these monuments but also risk depriving humanity of crucial archaeological information and artifacts, which are key to understanding our collective past.

This article explores a novel approach that leverages the capabilities of satellite-based remote sensing techniques for monitoring CH sites under shallow water conditions. A wide array of data will be used for a more frequent and comprehensive analysis of the site's condition over time, enabling the detection of subtle changes that might go unnoticed with conventional methods.

The case study focuses on the submerged port of Amathous archaeological site along the coast of Cyprus. The site's unique geographical and historical characteristics make it an exemplary model for applying advanced remote sensing technologies.

By integrating satellite data with on-site ground truth measurements (topographical and aerial-born imagery), the study aims to develop a robust framework for the preservation and protection of underwater CH sites. This approach can not only enhances the understanding of the impacts of CC and human activities on these sites but also paves the way for developing proactive measures to safeguard heritage assets. The findings from this study are expected to contribute significantly to the field of heritage conservation, offering scalable and efficient solutions to monitor and protect CH sites worldwide.

The Svalbard archipelago lies 1100 km south of the North Pole and 800 km north of the Norwegian coast. The region is one of the most important and strategic terrestrial nodes on Earth, separating the Greenland Sea, the Barents Sea, and the Arctic Ocean. The cultural landscape reflects human life and activity in a harsh and fragile environment.

We present here the preliminary results of the pilot site from the Thetida project – the coal cableway station at Hiorthhamn, 1917 (Taubanestasjonen i Hiorthhamn). The study area was extended to the “town” of Longyearbyen, located across the bay from Hiorthhamn. Longyearbyen is the settlement with the largest number of Svalbard residents (approximately 2500) and with an impressive number of protected cultural heritage sites – approximately 400. The total number of protected cultural heritage sites in Svalbard is 4590.

Previous studies have shown that the main risks to the Hiorthhamn site are coastal erosion, permafrost degradation, rockfall, thaw slumps, snow avalanches, surface erosion and thermo-erosion gullies, weathering, river flooding, and solifluction. Previous data (NPI orthophotos from 1936, 2009 – 2011, field surveys with UAV and total station in 2019 and 2020) and the most recent remote sensing data (Planet Sky Sat images – 2023) are used to assess the risk of degradation. Coastal erosion, calculated with the help of DSAS, for the sector where the site is located, shows high erosion rates of −0.77 m/yr (for the period 1927-2020) when compared to other studies from Svalbard. The latest forecast analysis estimates that the entire area will be eroded over the next two decades.

Furthermore, previous studies have shown that InSAR-based time series of land deformation appears to show continuous subsidence over permafrost regions in recent years. In this study, a method based on persistent scattering interferometry was used to estimate land deformation in the wide area of Longyearbyen, Svalbard. The InSAR-based land deformation estimates were calculated by processing 268 Sentinel-1 images from early 2018 to late 2023. Within the city of Longyearbyen, regions of stable, uplifting, and subsiding ground motion were identified. The land deformation results were interpreted by considering in-situ permafrost data and building characteristics, such as roof material, age, and heating mechanisms under building foundations. The results are important for better understanding the dynamics of the permafrost landscape under a warming climate and for predicting flooding using SAR altimetry data. The study makes a significant contribution to the protection of cultural heritage. The coal cableway station is the most iconic and visible object in Hiorthhamn, so much so that it can be seen from Longyearbyen, encouraging tourists to take a boat or a kayak to visit. Longyearbyen is the main tourist attraction on the island. It is therefore important to assess and monitor the risk of degradation so that, together with the local authorities, the most sustainable and climate-friendly measures can be taken for future generations.

The Ramps of Piazzale Michelangelo (Michelangelo Square) in Florence are a pedestrian connection between the Arno riverside and the higher Piazzale Michelangelo, leaning against the side of the hill called "Monte alle Croci," a hill delimiting Florence to the south. Over the years, this area has experienced a long series of instabilities that have affected some of the most significant testimonies of the city's architecture. The Ramps of Piazzale Michelangelo are popular both with tourists visiting the city and with the residents of Florence, who use them as a picturesque place to stroll.

The Ramps and contiguous Viale dei Colli (Hills Avenue) are one of the most interesting projects of the architect Giuseppe Poggi during the period when Florence was the capital of Italy (1865-1871). The staircases of the Ramps feature stone balustrades, topped with Pietraforte sandstone caps. Geologically, Pietraforte is a turbiditic sandstone characterized by numerous sedimentary layers typical of the Bouma sequence and by the presence of secondary calcite veins. These features are the main weak points where detachment phenomena can occur.

The action of rainwater leads to the dissolution of calcium carbonate, present both in the calcite veins and in the carbonatic cement within the rock. In the first case, this mechanism can result in the decohesion of the rock with the complete opening of veins and possible detachment and fall of blocks (even blocks with volume up to about 50 dm3). In the second case, detachments occur as a superficial exfoliation rather than detachments of entire portions of material.

Recent restoration works, completed in May 2019, focused on the conservation and recovery of architectural elements. However, in July 2020, a wedge collapsed, hitting a vehicle below. Subsequently, as a temporary countermeasure, the parapets were covered with nets to prevent new possible accidents.

For a long-term countermeasure, this architectural problem has been investigated assimilating it to a rockfall scenario. First of all it was necessary to manually detect and evaluate every block's discontinuity to assess susceptibility. An equation for calculating the risk of each identified block was then implemented. Differentiated interventions were proposed for each block based on its possible kinematics.

Using an approach based on statistical analysis of the rockfall’s susceptibility, this study aims to: 1) Quantify the spatial distribution of rockfalls; 2) Build an equation to identify the more dangerous blocks; 3) Propose safety interventions with minimal impact, diversifying them based on the kinematics of each individual block.

 

Keywords: Cultural Heritage, Stone element risk, rockfall, road safety, susceptibility.

The TRIQUETRA EU research project embarks on a pioneering initiative aimed at enhancing climate change (CC) resilience in Cultural Heritage (CH) sites. Within the scope of TRIQUETRA, certain provisions have been made for studying the geological and historical climatic data towards risk identification that the pilot CH sites of the project are facing.  The geological risk quantification was based on monitoring and modelling approaches to classify the intensity of geohazards related to ground instabilities, earthquake-induced effects, coastal retreat, sea-waves, water runoff, wind storms, wildfires etc. Digital twins derived by in-filed monitoring and surveying are assumed at the basis of geohazard quantification. Similarly, the assessment of historical climatic information has been based on observations and a multi-model ensemble of high-resolution Regional Climatic Model (RCM) simulations, aiming to identify potential risks at the selected CH sites. The datasets will be used for further experimentation, and continuous collection of new data will take place throughout the course of the project, serving towards the proposal of mitigation action against the CC-induced risks. 

Similarly, emphasis was given to gather information from past initiatives and directives to create a node of reference for the future, crucial for understanding the vulnerabilities of CH sites in the face of CC. An extensive literature review on CC and other risks and mitigation measures for CH sites worldwide has been made, in addition to gathering of existing and historical site-specific data, identification of geological conditions at CH sites and classification of geological hazards associated with environmental and climatological data that pose direct or indirect risks to the pilot CH sites.

The development of the TRIQUETRA Knowledge Base platform (an electronic repository) based on the retrieved data, accompanied by advanced search tools and a “Self Service Portal” hosted on the project website (https://triquetra-project.eu/), ensures that contents related to CC, geological conditions, historical data, site-specific information, as well as risks and mitigation measures for CH sites are discoverable for future decision-making actions. The Knowledge Base platform includes a dedicated database and a WEBGIS platform, which store collected data in a common geospatial database providing a secure environment, which has an open access policy and will offer further analysis beyond the end of the project.

The above lay the groundwork for holistic research to CC resilience in CH sites. The findings presented herein not only advance the objectives of the TRIQUETRA project but also offer insights that can guide future research in the preservation of global CH in the face of an ever-evolving climate.

Policies are a deliberate system that defines action and guides short-term decisions in pursuing a goal. Policy is a fundamental instrument of governance which is extensively used worldwide. However, not all policies are created equally. Contemporary literature is littered with examples of policy failures, and a large research emphasis is dedicated to co-creating ‘good’ policy. This challenge of developing good policy is exacerbated when we consider the rapidly evolving risks related to climate change. The evolving risks can make it difficult to define valid policy goals over the longer term. Furthermore, stakeholders are increasingly needed across policy and practice to overcome siloed working and co-create transdisciplinary risk management policies, considering both long-term strategic objectives and short- to medium-term operational solutions. Risk management policy instruments are relevant across spatial scales and engage with policies from other disciplines (urban planning, heritage conservation, environmental management). The article presents an innovative tool called the policy matrix to address challenges faced by policy experts. The policy matrix capitalises upon the co-creative research of the Organigraphs technique defined by Durrant et al. (2021) to co-create disaster risk management governance maps.  The article compares two policy matrices developed as part of a Horizon 2020-funded project called SHELTER. In its simplest form, a policy matrix arranges risk management policy instruments around an issue depending on their scale of implementation and disciplinary lens. This allows stakeholders to see all the policy instruments considered relevant to some specific issues. It can further provide stakeholders a robust platform to critique those policies.  By way of example, providing them with a tool to clearly “measure” the links between these policies, to identify policy gaps in thematic/operationalisation, or, from a practical perspective, to provide a tool for experts to review the level of participation in the design of these policies or the effectiveness of these policies in practice.

Climate change can have detrimental effects on biodiversity and people’s livelihoods and communities. Extreme weather conditions triggered by climate change significantly impact cultural heritage that represents tangible (i.e., historic sites, cultural landscapes) and intangible (i.e., knowledge, cultural practices, oral traditions) assets, especially in coastal areas and underwater sites. Inclusive risk monitoring, preparedness, and management are necessary to identify and ward off additional threats, and to promote inclusive and sustainable adaptation and safeguarding of the heritage sites.  

Stakeholder and end-user engagement is gaining ground in risk mitigation and monitoring impacts of climate change to support co-creation processes for climate adaptation strategies. Stakeholders often have valuable knowledge, insights and expertise, and their engagement allows collection of diverse perspectives and data, which can lead to better-informed decisions and identify potential risks and opportunities. However, it can also be difficult to establish collaboration and open communication among different actors and parties. This paper presents the potential of Living Labs (LL), a participatory social innovative methodology, that functions as multi-stakeholder platforms. LL create interaction spaces in which multiple stakeholders and end users collaborate in creating new solutions to complex problems. 

This paper presents the initial stage of development and testing of the LL methodology to be implemented in seven pilot sites of underwater and coastal heritage across three different Europe oceanic climates that are vulnerable to varied impacts of climate change. Results present common challenges in the identification of diverse range of stakeholders and their engagement in co-creation processes of value and impact assessment, decision and future making, as well as testing and validating of a new crowdsourcing tool in real-life contexts. The goal has been building inclusive multi-stakeholder communities for establishing sustainable participatory processes for co-designing and co-creating risk assessment and adaptation strategies that take sociocultural values at their core. For this purpose, a LL toolkit has been developed that compiles different sets of tested methods that have been applied in the case studies adaptable to local contexts.  

This paper will show the outcomes of a training workshop and the preliminary results of the adopted and tested LL tools and processes in which stakeholders from pilot sites identify heritage inherent values based on sociocultural relationships. Results highlighting diverse understandings of climate impacts and challenges but are also expected to show a shift on peoples’ perspectives when providing meaning to climate change impacts. Such insights and feedback are discussed in terms of strengths and weaknesses that are unique to the site, as well the LL methods and tools employed in each site. Such exercises are increasingly needed to customize participatory methods adapted to fit integrated multiple hazard assessment tools and strengthen sustainable pathways for cultural heritage management. Overall, these processes will contribute to better understanding of the complexity of climate impacts, not only on heritage, but also in related social dynamics.

Climatic risks and natural hazards pose a serious threat with long lasting impacts on cultural heritage, as well as on people’s livelihoods and connected communities. It is therefore considered of major importance to better understand the multivaried impacts of climate change on coastal and underwater cultural heritage through the active involvement of scientists, citizens and other relevant stakeholders in citizen science to engage them in data collection and involve their diverse perspectives, reflections and relationships with heritage for multi-hazard and risk monitoring.

This study focuses on exploiting the full potential of digital solutions together with co-creation and co-design processes through citizen science, crowdsourcing and participatory Living Lab methodologies. The main goal is to help citizens identify the values of coastal and underwater heritage, to understand the risks, and engage them in monitoring the changes and documenting the impacts of climate change and natural hazards on the heritage elements to collaboratively develop sustainable preservation and adaptation strategies. An immersive mobile application will be developed to raise awareness to citizens and their communities about digitalization and its benefits for cultural heritage protection and preservation. The proposed technological advancement exploits Augmented Reality (AR) technology to seamlessly integrate in-situ and remotely sensed data, effectively bridging the gap between valuable underwater cultural assets and a broader audience, that may not have had the opportunity to experience them otherwise.  

The digital solution is being co-designed and co-developed with citizens and their communities exploiting immersive crowdsourcing techniques using user-centered applied research and open innovation approaches. It employs crowdsourced techniques to promote the appreciation of the tangible and intangible heritage assets, empowering communities to actively participate in preserving and showcasing their cultural treasures. Citizens will be able to share their feedback, observations, comments and other data considered relevant to establish their unique point of view. The mobile application will then facilitate the demonstration and visualization of sensed data obtained by underwater and coastal crowdsensing units provided to the community (e.g. fishing boats, divers) to inform about environmental parameters, providing a comprehensive understanding of heritage dynamics and potential risks. Finally, the proposed digital solution will enhance citizen engagement, creating immersive experiences through AR features that bridge the gap between the past and present, fostering a deeper connection between people and their cultural legacy.

The immersive digital solution is being co-developed with seven different demonstration sites across Europe and will also be made available to a large stakeholder community at the end of 2024 for the first iteration of user feedback. Together, these functionalities establish a powerful tool for the proactive management and protection of heritage while actively involving and raising awareness among connected communities.

Cultural landscapes represent the intersection of natural and cultural heritage, encompassing the physical environment as well as the cultural practices, traditions, and values associated with a specific place. These landscapes often have important socioeconomic and community dimensions, serving as centers of livelihoods, tourism, and community identity. Moreover, these landscapes have intrinsic value and contribute to the overall diversity and richness of our global heritage. They hold stories, knowledge, and traditions that connect us to our past and shape our collective identity.

Climatic and anthropogenic hazards pose significant risks to these landscapes, including the degradation or loss of cultural heritage sites, changes in traditional land-use practices, and the erosion of cultural identities and knowledge systems.

To understand and evaluate these potential impacts, helping to safeguard and preserve the cultural significance and integrity of these landscapes, it is necessary to identify the specific risks and vulnerabilities that cultural landscapes face, allowing for the development of targeted adaptation strategies, enabling proactive measures to mitigate the impacts and ensure the resilience and continuity of these landscapes for future generations.

One widely adopted tool for risk assessments are Impact Chains [1], i.e., cause-effect models that describe the relationship between a hazard (e.g., a storm surge, a heatwave), exposed elements (e.g., residents, birdlife, agricultural practices) and their vulnerability (e.g., dike maintenance practices), and resulting impacts (e.g., coastal erosion). Impact Chains are composed of all these elements and additionally, intermediate impacts, i.e., cascading effects related to hazard and vulnerability elements. Impact Chains are typically developed through participative processes that involve local stakeholders. These stakeholders provide valuable input and feedback for the development of the Impact Chain. The validated Impact Chain provides a structured representation of the cause-effect relationships associated with the investigated risk.

Until now, Impact Chains have mainly been used as a basis for indicator-based Climate Risk and Vulnerability Assessments from the national to the local level, but not for modelling anthropogenic hazards like over-tourism or the abandonment of agricultural practices. In addition, only few Impact Chains for cultural sites have been developed.

In this contribution, we present Impact Chains that have been developed for five cultural landscapes as part of the Horizon Europe project RescueME (GA No. 101094978) and cover both climatic as well as anthropogenic hazards. These Impact Chains have been developed within case studies of the island of Neuwerk in the Waddensea of Hamburg (Germany), the Huerta and Albufera de Valencia (Spain), the Defensive System of the City of Zadar (Croatia), the region of Portovenere, Cinque Terre and the Islands (Italy), and the UNESCO Geopark in Crete (Greece). This contribution will describe the co-creation process for Impact Chain development, the involved stakeholder types, as well as the adaptations made to the standard Impact Chain representations [1].

Coastal and underwater cultural heritage play a crucial role in local and regional cultural resources. However, this tangible cultural heritage is under threat due to extreme weather events, changing conditions caused by climate change, natural hazards, and environmental pollution. This study aims to understand how end users (entities or people related to or who interact with heritage sites ) perceive these risks and what they need to better cope, adapt, or be resilient to the anticipated changes. Additionally, it explores how science can address the needs and requirements of local and regional end users.

This research is part of the larger THETIDA project, focusing on technologies and methods for improved resilience and sustainable preservation of underwater and coastal cultural heritage, funded by the European Union’s Horizon 2020 research and innovation programme. The THETIDA project concentrates on seven pilot sites, comprising coastal locations such as Svalbard in Norway, Ijsselmeer in the Netherlands, Mykonos in Greece, and underwater sites including Algarve in Portugal, Gallinara and Spezia in Italy, and Paralimni in Cyprus.

The THETIDA team conducted surveys to analyze threats, needs, and preservation requirements for each pilot site, incorporating data from consortium partners and workshops held with local stakeholders in several pilot sites. The results identified material deterioration and human-induced development interventions as primary threats. Essential needs include assessing risk and exposure to various hazards, implementing conservation measures for buildings and sites, and promoting awareness, education, and training.

Survey responses unanimously emphasize the critical requirement for site assessment and risk evaluation concerning both human-induced and climate changes. These findings offer valuable insights for developing tools and services within the project to support local and regional end users. Furthermore, they underscore the importance of fostering a scientific culture among communities, a role that science centers and museums can fulfill, as verified during the 2023 Portuguese Science and Technology Week.

Finally, the resulting end-user ecology is integrated into the Living Lab methodology, another facet of THETIDA Project research, aiming to co-create, test, and validate a new crowdsourcing tool in real-life contexts.

Climate change poses a significant and alarming threat to cultural and natural heritage in urban and rural areas, jeopardizing the preservation of tangible and intangible aspects of our shared human history, including cultural traditions, knowledge, and practices. Rising sea levels, extreme weather events, and increased temperatures contribute to the degradation of cultural sites. Coastal regions face the imminent danger of inundation and erosion, endangering landscapes that have withstood centuries. At the same time, Indigenous communities are vulnerable, as their cultural heritage is often intricately connected to specific ecosystems and landscapes. On top of these climatic threats, cultural and natural heritage is also threatened by impacts from anthropogenic stresses, like unsustainable tourism and consumption patterns or environmental pollution.

Against this backdrop the H2020 projects ARCH, HYPERION, and SHELTER founded the EU R&I Task Force for Climate Neutral and Resilient Historic Urban Districts in 2021. The task force aims to bring together diverse groups of practitioners, researchers, and policy makers at the cross section of heritage management, climate change adaptation / mitigation, disaster risk management, and sustainable development. This coincides with the objective to identify and discuss current developments in research and practice; bridge knowledge gaps between these fields; boost collaboration among the cross-sectoral actors involved; and ultimately make our historic areas more climate neutral and resilient. In doing so, the task force aims to provide practical support to European authorities and decision makers for developing harmonised, evidence-based policies, strategies, and procedures. The Task Force has thus far convened three times: June and December 2021, and June 2022, and resulted in a joint white paper, Paving the Way for Climate Neutral and Resilient Historic Districts.

With the successful conclusion of the three funding projects, the work of organizing the task force has been taken over by their follow-up projects RescueME, THETIDA, and TRIQUETRA in 2023, shifting the focus from urban districts to historic areas, encapsulating cultural and natural heritage in urban and rural areas and other cultural landscapes, including coastal and underwater heritage.

In this presentation, we present the last results of the task force, the way forward regarding its development and activities within the updated partnership, and potential collaboration opportunities with other initiatives, projects, and actors.

According to the Intergovernmental Panel on Climate Change (IPCC) coastal risks are projected to increase by at least one order of magnitude over the 21st century due to committed sea level rise, impacting cultural and natural heritage in coastal areas. Amidst the urgency of climate change adaptation and mitigation, which often exceeds available public budgets, there is a growing recognition of the vital role played by innovative financing strategies and business models .

The existing body of knowledge on resilience financing for cultural heritage and landscapes is somewhat fragmented and primarily focuses on the conservation or reuse of the built heritage. Few studies addressed the financial strategies for productive cultural landscapes. Unlike conventional cultural heritage categories such as historical monuments, archaeological artefacts, and museum collections, productive cultural landscapes are dynamic socio-ecological systems. Consequently, their resilience demands a holistic approach that addresses not only the physical dimension but also ensures the continuity of underlying activities, such as agriculture, forestry, and fishery.

As part of the  “RescueMe” project – focused on equitable resilience solutions to strengthen the link between cultural landscapes and communities – this study aims to consolidate fragmented knowledge. It seeks to provide an initial state-of-the-art overview of existing financing strategies, with a specific focus on productive cultural landscapes, such as agricultural landscapes. Based on a systematic review of existing literature, databases, and drawing insights from prior projects, this study presents a thorough review of innovative financial strategies. This encompasses economic, financial, and business models that have the potential to leverage regenerative capital investments in landscape resilience.

The study reveals dominant themes and categories of financing strategies for the resilience of productive cultural landscapes. The selected innovative financial strategies will be gathered in the RescueME resilience meta-repository, to offer an integrated searchable database of solutions, elaborated jointly with the researchers from the Università di Bologna and the Conexiones improbables, with the consultation of partners representing resilience landscape laboratories (R- labscapes) of the project.

The findings offer valuable insights for policymakers, businesses, and cultural institutions seeking to develop strategies for scaling up investments. This contribution is instrumental in navigating the complex landscape of innovative financing, providing actionable knowledge for sustainable and effective decision-making. The information available in the meta-repository will be accessible for reuse to a wide-range of stakeholders, including policymakers, researchers and practitioners.

The TRIQUETRA project seeks to establish an evidence-based assessment platform for precise risk assessment. Functioning as a Decision Support Tool, this platform aims to enhance efficiency in risk mitigation and site remediation. The TRIQUETRA project's overall approach is structured around three key elements: (i) Risk Identification, (ii) Risk Quantification, and (iii) Risk Mitigation.

Within this framework, a novel Knowledge Base Platform (KBP) has been created, serving as an electronic repository equipped with advanced search tools and capabilities. It encompasses information on Climate Change (CC), geological, historical, and site-specific data, along with risks and mitigation measures for Cultural Heritage (CH) sites based on the verified data, geographical identification and results obtained from the outputs of the project.

The primary goal of the KBP is to comprehensively integrate and visualize all shared project data, utilizing both a searchable literature database and a sophisticated WebGIS platform that adheres to the standards set by the Open Geospatial Consortium (OGC) and INSPIRE. It also incorporates various features for the deployment, cataloguing and categorisation of the data produced and shared within the project, to enhance the discoverability of the data. The KBP is structured based on two distinct key components, namely the Bibliography inventory and the WebGIS. These distinct sections of the platform gather all the data and information related to the pilot CH sites of the project. The combination of available datasets for each pilot site leads to the creation of a data cube - a multidimensional structure facilitating the efficient representation and analysis of data across various dimensions, including time and location.

It is imperative to point out that the platform will keep evolving throughout the course of the project in order to align with upcoming project outputs, enabling the fusion of different data types and efficient research on each pilot CH site. This, in turn, contributes to advancing knowledge in CH monitoring and facilitating optimal preservation and risk mitigation actions.

Since 2019, a team of scientists, technicians, and politicians from Southern Portugal has been planning and implementing a new project aimed at involving the local population in fostering sustainable development alongside the preservation and conservation of natural and cultural assets. This initiative has evolved into the aspiring UNESCO Global Geopark (aUGGp) Algarvensis, reaching maturity earlier this year when its southern territorial boundary was established at sea, aligning with a bathymetric depth of 130 meters, representing the coastline of 20,000 years ago.

Situated in the Algarve region, this territory is facing several threats associated to climate change, the most significant ones being the sea level rise, reduced rainfall and freshwater availability, and the impact of the extreme events.

The natural and cultural heritage assets are abundant, both on land, along the coast, and underwater. Given the diverse stakeholders responsible for their management based on their type, characteristics, size, and location, there has been no global and integrated approach to assessing their vulnerabilities, both specific and common. The aUGGp Algarvensis aims to rectify this by identifying, quantifying, and mitigating risks drived from natural, climatic, anthropogenic, and biological hazards across various types of heritage.

Although relatively unknown, the continental territory of the aUGGp Algarvensis boasts a rich and diverse cultural heritage, featuring over 228 listed and referenced sites encompassing various types of heritage. Over the last decades, several coastal heritage sites have vanished into the sea due to intense coastal erosion, with underwater heritage primarily appreciated by divers..

This study explores how climate change poses risks to the region's geological, cultural, and ecological features. It emphasizes the intricate relationship between environmental changes and heritage preservation within the context of the UNESCO Global Geopark Algarvensis initiative. Our goal is to not only present the survey and compilation data gathered so far under the aUGGp Algarvensis coordination but also to underscore the importance and impact that such a local/regional non-governmental structure can bring to implement an efficient and proactive management strategy in the face of evolving risks to heritage.

Climate change and natural hazards pose significant threats to heritage sites, with major impact on people's livelihoods and connected communities. Increased frequency and intensity of extreme weather conditions have a substantial detrimental impact on cultural heritage (CH), both on tangible assets (e.g. monuments, historic buildings, and sites), and intangible elements (e.g. knowledge, cultural practices, and oral traditions) that are inherited from the past. Factors contributing to the deterioration of heritage sites are attributed to sea level rise, ocean acidification, intensified storm activity, temperature elevation, and coastal erosion that put significant stress on the stability, preservation, conservation, and security of both tangible and intangible cultural heritage in underwater and coastal environments.

However, limited knowledge exists on risk assessment and protective measures actions to mitigate these multiple hazards and complex risks posed by climatic conditions and natural disasters. This highlights the need for more integrated assessments that consider the collective impacts of various hazards on cultural heritage and their corresponding protection systems. It is therefore of significant importance to employ and test the effectiveness of novel measures across a spectrum of heritage sites threatened by various climatic conditions and risks.

Addressing these two points, the THETIDA project focuses on the development of a preventive conservation strategy that includes monitoring, risk preparedness and management, for underwater and coastal CH. The main objective is to identify and ward off climatic risks and natural hazards and promote adaptation, reconstruction, and other post-disruption strategies to restore normal conditions to the historic area. THETIDA project also emphasizes long-term strategic approaches to adapt to climate change and to wield policy tools for economic resilience. This is achieved through an interdisciplinary team of researchers, experts and practitioners that will develop, test and validate an integrated multiple heritage risk assessment and protection system with evidence-based monitoring frameworks, innovative tools and instruments and through participatory and crowdsourcing processes. The project actions will be implemented at seven pilot sites across the European continent, linking social innovations with state-of-the-art technologies, including ICT and IoT harmonised tools, to enhance resilience of underwater and coastal heritage sites.

Submerged underwater cultural heritage (UCH) provides insight into past human behavior and history and thus the preservation of these artifacts at the site of discovery is crucial. However, marine environmental conditions such as physical, chemical, and biological processes directly impact the degradation of these underwater historical sites. Under the frame of the Horizon Europe project THETIDA (Technologies and methods for improved resilience and sustainable preservation of underwater and coastal cultural heritage to cope with climate change, natural hazards and environmental pollution), which runs between 2023 and 2026, the current work aims to demonstrate the suitability of process-based numerical models to (1) predict in real-time hazards threatening UCH sites associated with currents and sediment abrasion and (2) to estimate the risks associated with these oceanic conditions. This general approach is demonstrated for the Coast of Algarve (southern coast of Portugal), focusing specifically on the B-24 wreck. This WWII bomber airplane rests on the bottom of the coastal shelf at 20 m deep and approximately three kilometers offshore of Praia de Faro. The methodology couples a wave model (SWAN) to an existing operational hydrodynamic system SOMA powered by the MOHID model, which will provide inputs to run a non-cohesive sediment transport model. In-situ measurements and laboratory experiments will be used to determine deterioration rates that will provide insights into risk categorization and impacts on UCH sites. The final product will be a demonstrative operational ocean model for UCH management, assessment, and emergency response.

Within the framework of TRIQUETRA (Toolbox for assessing and mitigating Climate Change risks and natural hazards threatening cultural heritage; https://triquetra-project.eu/) research project, meteorological data from weather stations (observations) as well as simulations from regional climate models (RCMs) have been analyzed to assess recent past and future climate change over eight cultural heritage (CH) sites in six countries. From South to North the CH sites are Choirokoitia in Cyprus, Aegina, Epidaurus, and Kalapodi in Greece, Ventotene in Italy, Les Argilliez in Switzerland, Roseninsel in Germany, and Smuszewo in Poland. The observations were acquired from weather stations (from various networks) with long meteorological records at the proximity of the examined CH sites, while the RCM data come from the EURO-CORDEX. More specifically, 11 sets of high resolution (~12.5 km) RCM simulations were analyzed, covering the historical period 1950-2005 and the future period 2006-2100 under three different Representative Concentration Pathways (RCPs) of the Intergovernmental Panel on Climate Change (IPCC), namely the RCP2.6 (strong greenhouse gas mitigation), RCP4.5 (medium mitigation), and RCP8.5 (no further mitigation). The climate analysis over the recent-past period 1970-2020 revealed a robust warming and increasing of heat stress at the materials of the CH assets. Furthermore, the multi-model climate analysis based on the RCM simulations for the three different future scenarios points towards a hotter and drier future climate for the CH sites at the South and a hotter and wetter climate for the CH sites in the North. Analysis of the Heritage Outdoor Microclimate Risk (HMRout) and Predicted Risk of Damage (PRD) indices over the recent past period indicates notable variations in microclimate conditions with aggravation of heat stress at CH assets made of stone and marble, pointing towards an increase in predicted risk of damage. Analyzing the future changes in HMRout and PRD indices based on the multi-model ensembles of RCM simulations for the three different future scenarios will provide a more comprehensive understanding of how the resilience of materials and the overall preservation of stone and marble CH sites may be affected.

This work is based on procedures and tasks implemented within the project “Toolbox for assessing and mitigating Climate Change risks and natural hazards threatening cultural heritage - TRIQUETRA”, which is a Project funded by the EU HE research and innovation programme under GA No. 101094818.

Climate change is likely to have a direct impact on tangible cultural heritage. Cultural heritage sites are already experiencing the impact of variations in temperature, precipitation, atmospheric moisture, and wind strength, along with rising sea levels and shifts in the frequency of extreme events. Leveraging remote sensing tools presents an opportunity for the effective surveillance and detection of potential threats to Cultural Heritage sites, along with monitoring the material deterioration in monuments. Since monuments are not isolated in the geographical space, assessment and evaluation of changes in their broader area are important because they serve as warning signals to the concerned stakeholders and facilitate them to take measures for preventing CH asset damages. Satellite data after appropriate processing provide significant “background” information by pointing out a) hazards with a slow or gradual onset in the broad area of the CH monuments and facilitating change assessment including ground deformation and land cover changes and b) assessing damage on both the surrounding region and the monuments after events like floods, landslides, earthquakes, etc.

Within HYPERION project (https://www.hyperion-project.eu/), RS-based methods have been developed for routine monitoring of the CH sites and were tested at four pilot sites. Routine monitoring includes displacement and land cover change detection maps of the broad area for all the pilot sites that are studied within the Hyperion project (city of Rhodes, Granada, Venice and Tønsberg), flood monitoring maps, three-dimensional models for all the CH assets, and deterioration and material loss estimation for specific parts of the facades of two monuments in the pilot site of the city of Rhodes, the Fort of Saint Nikolas and the Roman bridge in the Rhodes island.

To this end, a) advanced methodologies using PS and SBAS functionalities and Convolutional Neural Network architectures have been applied on satellite data aiming to produce reliable land deformation and land cover change detection maps, respectively, b) time series analysis and classification have been employed to identify changes in backscattering and to map flood occurrences, c) point clouds, light models, texture models and sections have been created in order to obtain a detailed 3D representation of the assets, and c) hyperspectral processing methods have been employed for fast and efficient assessment of the material deterioration level.

The effectiveness of the developed methods has been evaluated through their implementation on the pilot sites and disseminated to the scientific community through relevant publications. This paper presents a comprehensive overview of the results they have achieved and highlights the capabilities of remote sensing as a valuable tool in preserving Cultural Heritage.

The increasing recognition of the importance of resilience in various sectors, such as disaster risk management, climate change adaptation, and urban planning resulted in a growing demand for tools and frameworks that can effectively measure and evaluate resilience. Scorecard approaches for the assessment of resilience have become more prominent in recent years. They provide a structured and quantitative way to assess resilience, allowing a monitoring of the resilience building progress of different systems or communities. In addition, the complexity and interconnectedness of modern systems requires a comprehensive assessment of resilience, considering multiple dimensions and factors. Scorecards offer a holistic view by incorporating various indicators and metrics, providing a more comprehensive understanding of resilience and its strengths and weaknesses. Scorecard approaches also facilitate decision-making and planning by providing clear and actionable information, enabling stakeholders to identify areas of improvement, prioritize interventions, and track progress over time.

Until recently, no scorecard approach for the assessment of the resilience of historic areas existed. The ARCH Resilience Assessment Dashboard (RAD) [1] closes this gap by providing an online scorecard that allows heritage managers, urban planners, disaster risk managers and other actors to jointly self-assess the resilience of their historic area.

The core of the RAD are 221 questions, categorized into ten overarching Essentials – an adapted version of the Ten Essential for Making Cities Resilient [2] – three disaster risk management phases, four topics (disaster risk management, climate change adaptation, heritage management, social justice), and six resilience dimensions (built environment, natural environment, economy, policy, society, and culture). Each question is answered on a 6-point Likert scale and supported by explanatory information, including potential stakeholders who have the information needed to answer the question.

The RAD provides users with a score, which indicates the performance in the different aspects relevant to building resilience. By analyzing the results, users can identify weak points in the resilience of the historic area. Based on these results, users can formulate a list of actions for increasing the resilience. To support this process, the RAD is linked to the ARCH Resilience Measures Inventory, an online database of resilience measures compatible with the Essentials of the RAD. By conducting several resilience assessments, the RAD can also be used to monitor resilience over time.

The RAD was co-developed and evaluated for four historic areas as part of the Horizon 2020 project ARCH (grant agreement No. 820999): the Old Town of Bratislava (Slovakia), the Old Town of Camerino (Italy), the World Heritage Site Speicherstadt and Kontorhausviertel in Hamburg (Germany), and the Huerta de Valencia (Spain).

This contribution will introduce the concept of the RAD and present the results of its trial application in the four historic areas.

This research, conducted within the THETIDA project (https://thetida.eu), focuses on identifying threats posed by climate change to underwater cultural heritage sites, with a specific emphasis on the diverse risks – both direct and indirect – that endanger metallic materials, such as anchors, cannons, and structural elements. Notable pilot sites within THETIDA include the US Army WWII PB4Y-1 bomber aircraft Liberator off the coast of Praia de Faro (Portugal), the sunken submarine chaser Equa near La Spezia, and an Ottoman shipwreck in Famagusta bay, Cyprus. These sites offer varied historical backgrounds, construction materials, and biological ecosystems, enabling a comprehensive comparison between sites protected in bays and those in dynamic open ocean environments with currents, sediment dynamics, and biological actions influencing deterioration processes [1].

Being aware of successive reports of the Intergovernmental Panel on Climate Change (IPCC), documenting climate phenomena such as rising sea levels, ocean surface temperature increases, ocean acidification, changes in ocean circulation, extreme wave events and deoxygenation [2], the objectives of the research are to investigate the deterioration effects associated with climate change, assess their evolution across different environments, and develop prediction models. The ultimate goal is to provide practical recommendations for site preservation. The methodology involves studying the sites, historical backgrounds, material compositions, and deterioration characteristics, including physical, chemical, and biological factors of underwater weathering, classification of decay patterns, biocolonisation and biodeterioration characteristics through a multidisciplinary approach. In underwater heritage sites, materials undergo physical, chemical, and biological changes influenced by water, sediment, and living organisms [3, 4]. The study will consider variables such as temperature, salinity, pH, oxygen levels, and the intensity and direction of currents, alongside the depth and location of the site. Mock-up samples will undergo accelerated weathering and autoclave corrosion tests to observe the degradation related to specific environmental parameters. Mock-up samples will also be placed in the real sites to compare the results with the controlled environment aged samples and explore the early stages of deterioration and biocolonisation.

This research contributes to understanding the impact of climate change on underwater cultural heritage sites, providing valuable insights for preservation efforts in the face of evolving environmental challenges.

Cultural heritage worldwide is of great interest for general public and scientific communities across disciplines. In the Mediterranean region, and in Greece in particular, historic buildings and monuments are widespread. Ongoing environmental change, and the increased frequency and severity of climatic extremes and natural hazards in the Mediterranean regions, challenge the protection of cultural heritage, making essential the detailed documentation and digitalization of these monuments in tailored geodatabases. In the present study, example historical buildings of Western Greece were selected, covering a wide environmental gradient from coastal to mountainous landscapes, namely, a 19th century emblematic stone-built lighthouse at Cape Drepano, close to Patras, in Northern Peloponnese, as well as historical buildings in the Aetolia-Acarnania region, including 19th and 20th century monuments in the lagoon region of Messolonghi (the Old Hatzikosta Hospital and the Palamas School), as well as a 18th century post-Byzantine monastery located in a mountainous area near Agrinio. Geodetic field surveys were conducted with Terrestrial Laser Scanning (TLS) and Unmanned Aerial Vehicle (UAV) photogrammetry. The collected point clouds were processed to generate Building Information Models (BIMs) of the examined structures which were then 3D printed at scale. The derived digital database of these monuments offers a detailed documentation and baseline of the present status of these monuments. This baseline, when combined with future field surveys, set the basis for accurate monitoring of the response of these structures to natural and anthropogenic stressors (e.g., costal erosion, land displacement, etc.). Moreover, this documentation could assist the efficient planning of maintenance and restoration interventions, while the derived digital and printed 3D models offer tangible tools for raising public’s awareness and valorizing further these historical buildings. Technological advancements in geodetic instruments as well as the continuous development of numerical tools for BIM applications, 3D modeling and printing, facilitate the seamless digitalization of cultural heritage and its archiving into interactive geodatabases, complementing existing efforts towards coordinated documentation and monitoring of historical buildings at national and international levels.

Cultural heritage (CH) sites face increasing risks from climate change (CC) and various hazards, posing threats such as rising sea levels, extreme weather events, and environmental degradation, endangering their preservation and long-term existence. A lot of research has been done on protecting CH sites, but we still lack systemic approaches towards identifying and mitigating risks to CH sites. The TRIQUETRA EU research project proposes a technological toolbox and a methodological framework for tackling climate change risks and natural hazards threatening CH, in the most efficient way possible. The main strategic objectives of TRIQUETRA include: the creation of a repository of knowledge on effects of CC and natural hazards on CH, including lessons learnt from existing mitigation measures; the implementation of a systemic approach towards identification of upcoming risks and hazards to CH; and the usage of novel technologies allowing efficient and accurate quantification of threats to CH.

The TRIQUETRA project’s methodology is structured around three fundamental stages: (i) identifying risks, (ii) quantifying risks, and (iii) mitigating risks, forming what is known as the “trifecta” approach. This approach constructs a robust framework for evaluating and addressing the following categories of risks: (i) climate-related risks; (ii) extreme water, snow and ice hazard risks; (iii) geological and geophysical risks; and (iv) chemical and biological hazard risks. Furthermore, it assesses the damage and failure modes of CH structures as well as the compounded effects of various environmental stressors on CH sites. TRIQUETRA will be validated in eight different CH sites across Europe. The main project results can be summarized as follows:

  • a novel risk quantification framework for CH sites;
  • an expanded knowledge base platform;
  • a decision-support platform (TRIQUETRA DSS) including risk severity quantification tools and mitigation measure selection and optimization tools;
  • novel protective materials;
  • a novel flash LiDAR;
  • water quality analysers; and
  • a CH site digitization framework.

As climate change progresses, shifting weather events are expected to become more severe [1], posing a significant threat to heritage sites but also to connected communities. The monitoring of climatic risks at coastal and underwater heritage sites is considered of significant importance to enhance understanding of degradation processes but it constitutes a resource-intensive and intricate process. Frequently, data collection from devices requires the coordination of expeditions for sensor retrieval and manual data acquisition. The monitoring area's spatial extent is limited due to the utilization of stationary sensors. Another challenge lies in the integration of both subaquatic and terrestrial parameters into an advanced monitoring solution that provides an unobstructed assessment of the hazards encompassing the heritage area.

The development of multiple low-cost sensors endowed with Internet of Things (IoT) capabilities, can facilitate real-time monitoring and positioning for both subaquatic and terrestrial data collection of environmental parameters that amplify the deterioration of heritage assets.

To address subaquatic data acquisition, an IoT Conductivity Depth Temperature (CDT) device has been designed to measure salinity and temperature characteristics with a dual role of a wearable sensor for divers and a static sensor affixed near the seabed. To streamline data transmission beyond aquatic environments, the device is engineered to transmit data when situated outside the water. The second subaquatic sensor developed serves the purpose of crowdsourcing and designed to be attached to vessels from local communities, enabling real-time data collection on salinity, temperature, and chlorophyll concentration. Both subaquatic devices integrate Inertial Measurement Unit (IMU), Narrowband Internet of Things (NB-IoT), and Global Navigation Satellite System (GNSS) technologies within their design.

The proposed coastal monitoring solution incorporates a weather station with the capacity to measure and transmit real-time data on diverse weather parameters, encompassing temperature, humidity, rain volume, wind speed, UV index, and light intensity. The fourth device integrates strain gauges and accelerometers, offering valuable data for both static and dynamic monitoring. This enables the assessment of vibration levels and provides information on the evolution of cracks and tilts within the monitored site. To optimize energy efficiency, all four devices have been engineered with low power consumption capabilities. Furthermore, devices located outside the water are equipped with solar panels to ensure complete energy autonomy.

In conclusion, the development of multiple low-cost sensors with IoT capabilities demonstrates a commitment to overcoming the financial and logistical complexities of data collection. By incorporating advanced technologies such as IMU, NB-IoT, and GNSS into subaquatic devices, we enhance the precision and versatility of real-time monitoring and positioning. By seamlessly integrating technological innovation with practical considerations, we aim to provide a comprehensive and efficient means of safeguarding these invaluable cultural and environmental treasures.

Underwater and Coastal Cultural Heritage (CH) sites face unprecedented threats from climatic risks and natural hazards, making their preservation, conservation and protection complex and challenging issues. One primary challenge for designing efficient preservation strategies is the absence of curated open data streams that could allow local authorities to have a better understanding of the evolving degradation parameters at CH sites. The existing data silos and the lack of circular, sustainable and curated open data ecosystems (ODE) also leave the key players (i.e., asset managers, local authorities, etc.) of the heritage sites and their connected communities defenceless as they are usually equipped with obsolete and coarse information, a condition that generates a knock-on effect on the adaptation and mitigation strategies against these threats.

This study focused on providing a methodological approach towards data circularity by leveraging on the Open Data Institute's (ODI) Data Landscape Playbook (DLP) methodology. The ODI DLP serves as a comprehensive guide for developing effective data ecosystems. By adapting this playbook to the unique challenges posed by underwater and coastal cultural heritage preservation, stakeholders can harness the power of data to enhance resilience, response, and recovery efforts in the aftermath of natural disasters. This specific methodology consists of four consecutive steps, involving the investigation of the context of the objectives of each pilot case, the identification of all the relevant Data Assets and Data Owners, and therefore details related to the interfaces/infrastructures and standardised data formats that are commonly adopted. The last pillar of this methodology is declared as a prerequisite towards the data circularity, as it tries to profile heritage sites perspectives regarding the ethical, legal, and regulatory context that is chosen based on the Data Spectrum classification so as to disseminate the data sources through the public. The DLP also emphasises the importance of data quality assurance and control measures, ensuring this way about the credibility of the existing information and acknowledging the best practices so as to succeed.

The engagement of diverse stakeholders under the prism of the ODI-DLP attempts to foster collaboration and partnerships among governments, archaeologists, marine biologists, and local communities, and thus facilitate to formulation of sustainable strategies for risk assessment and mitigation, forming the cornerstone of resilient preservation practices. Towards this process, community involvement not only enriches the data ecosystem but also facilitates the integration of traditional knowledge, ensuring a more holistic and culturally sensitive approach to CHs’ preservation. This ODI-DLP methodology is currently applied to seven underwater and coastal heritage sites of THETIDA project, i.e., Mykonos (Greece), Gallinara and Equa (Italy), Algarve (Portugal), Paralimni (Cyprus), Svalbard (Norway), and Ijsselmeer (Netherlands) and thus, will contribute to the digitalisation of each site, creating this way a framework towards the generation of resilient data ecosystems and pathways to improve and enhance CH protection.

It is acknowledged by International declarations and policy guidance documents that cultural heritage (CH) can contribute directly to many of the Sustainable Development Goals (SDGs), including resilience and adaptation to climate change (SDG 13). CH can support climate change action as it conveys local knowledge that builds resilience for change through mitigation and adaptation. Moreover, the vulnerability of the built environment to climate change possesses inherent resilient properties that allow it to resist damage. The integration of policies and practices of CH conservation into the wider framework of sustainable urban development entails the application of a landscape approach that (i) responds to local cultural contexts and value systems, (ii) integrates distinct theoretical perspectives to address the complex layering of the spatial, mental, and functional process-related dimensions of the landscape, and (iii) addresses policies and governance concerns at international and local levels (Ginzarly et al., 2019). Yet, the application of a landscape approach to CH conservation in the context of climate change is faced with different challenges.
First, while at the turn of the twenty-first century the concept of CH has extended from monuments to cultural landscapes and cities as living heritage, assessment processes have been slow to evolve and address the interdisciplinary nature of heritage (Déom & Valois, 2020). Second, there is a challenge around assessing the vulnerability of CH to climate change and integrating its vulnerability status into the broader context of sustainable urban development. This challenge is imposed by the lack of a framework that addresses landscapes rather than heritage sites in isolation (Cook et al., 2021).
To address the above-mentioned challenges, this presentation presents a landscape people-centered conceptual framework for resilient CH that is applicable at the city scale (i) to map how different stakeholder groups value heritage in the context of climate change, (ii) using social networks as a tool to engage communities and get access to information about heritage values, and (iii) assess the vulnerability of urban heritage and its associated values to climate change.The conceptual framework is structured around four prominent themes: (1) the city is a living heritage that encompasses the physical, mental, and digital heritage landscapes; (2) digitally mediated heritage practices provide new prospects for digitally-enabled forms of co-creation of heritage values; (3) longitudinal records on social media serve as a data source for the assessment of heritage values and their vulnerability to change; and (4) online communities contribute to communities’ disaster resilience.
