Historic areas (HAs) are highly vulnerable to natural hazards, including earthquakes, that can cause severe damage, if not total destruction. This paper proposes methods that can be implemented through a geographical information system to assess earthquake-induced physical damages and the resulting impacts on the functions of HAs and to monitor their resilience. For the assessment of damages, making reference to the universally recognised procedure of convoluting hazard, exposure, and vulnerability, this paper proposes (a) a framework for assessing hazard maps of both real and end-user defined earthquakes; (b) a classification of the exposed elements of the built environment; and (c) an index-based seismic vulnerability assessment method for heritage buildings. Moving towards the continuous monitoring of resilience, an index-based assessment method is proposed to quantify how the functions of HAs recover over time. The implementation of the proposed methods in an ad hoc customized WebGIS Decision Support System, referred to as ARCH DSS, is demonstrated in this paper with reference to the historic area of Camerino-San Severino (Italy). Our conclusions show how ARCH DSS can inform and contribute to increasing awareness of the vulnerabilities of HAs and of the severity of the potential impacts, thus supporting effective decision making on mitigation strategies, post-disaster response, and build back better.

Resilience, initially a concept rooted in psychology, has traversed disciplinary boundaries, finding application in fields such as urban planning and development since the 2010s. Despite its broad application, most definitions remain too abstract to allow their practical integration into urban planning and development contexts. Addressing this challenge, the European research projects SHELTER and ARCH offer a practicable integration of resilience with planning and development practices surrounding urban heritage. Following a systemic approach to resilience, both projects integrate perspectives from urban development, climate change adaptation, disaster risk management, and heritage management, supported with tools and guidance to anchor resilience in existing practices. This paper presents the results from both projects, including similarities and differences.

Risks related to climate change and natural hazards increasingly affect urban areas such as historic towns, old urban quarters, villages, and hamlets. These, as well as historic landscapes, make up a significant part of an urban area’s identity and cannot just be rebuilt or significantly changed without taking into account the historic value, cultural background, and prescribed regulations. Systematic resilience building for historic areas is becoming essential, and research supporting it will be in the spotlight. However, questions still exist concerning how to best transfer research results into practice at the community level. Standardization of resilience-enhancing methods and tools deriving from research projects is one option, chosen, e.g., for the EU-Horizon 2020 project ARCH. Within the project, a disaster risk management (DRM) framework has been composed and then transferred into a standard, supported by a co-creation approach involving relevant stakeholders. This article outlines the project’s different standardization steps and its impact on the development of the ARCH DRM Framework. It highlights the systematic inclusion of project-external stakeholders who actively contribute to the validation and enhancement of the ARCH DRM framework to guarantee maximum applicability in historic areas, supporting them in their fight against the impacts of climate change and natural hazards.

As the climate crisis accelerates, the resilience of Europe's aging critical infrastructure systems shifts more and more into focus. However, the rising interconnectedness of critical infrastructure systems and the dependency of their operation on multiple stakeholders makes approaches that target the resilience of isolated infrastructures insufficient and might even result in a decrease of the resilience of the whole system. This need for more resilience thinking in interconnected infrastructure systems has resulted in advances in risk analyses of supply chains and analyses of interdependencies in infrastructure systems from a Critical Infrastructure Protection/Resilience perspective. However, results from such analyses on the level of interconnected infrastructure systems have seldomly be broken down to the level of individual corporate value chains, a necessity as national/regional resilience efforts need to be supported on the local level. In this paper we therefore propose a novel approach for value chain climate risk and vulnerability analysis that combines a participatory, indicator-based approach with a semi-quantitative risk matrix approach to allow linking analyses from national to local scale and supports economic assessment of climate change impacts for individual businesses. This approach has been developed and prototypically applied in a case study in a German metropolitan area located at the Rhine River. The results allow to identify where along the dependency chains of interconnected infrastructure systems, hazards and impacts might manifest, which cascading (economic) impacts result on the level of individual infrastructure operators, and where resilience measures should be taken to be most effective and (cost) efficient.

Climate change is a major global threat to our society’s urban areas, with the majority of Europe's population living in cities and their cultural heritage. Historic districts of significant cultural value and the communities connected to these places have an important role to play in fostering location-based identity and economy, social cohesion, innovation, urban regeneration, and climate change adaptation. Thus, it is important to make historic districts climate resilient, by jointly considering climate change adaptation, disaster risk management, heritage management, and sustainable urban development. However, this is often a major challenge for local and regional administrators and relevant stakeholders. This paper constitutes the first major result of the EU R&I Task Force for Climate Neutral and Resilient Historic Urban Districts. It provides an overview of the challenges faced by practitioners and researchers when jointly addressing the needs of resilient historic districts and provides an initial set of recommendations produced by the task force to address these challenges. These challenges cover different issues around five topics (i) data availability, use and its management, (ii) the common responsibility fragmentation in policy and governance, (iii) the challenge on integrating local knowledge and traditions in resilience building, (iv) the difficulties around the co-ownership and co-production in governance and (v) the importance of mainstreaming heritage management in adaptation and resilience policies.
