Item Do we know how urban heritage is being endangered by climate change? A systematic and critical review(2021-11) Quesada-Ganuza, Laura; Garmendia, Leire; Roji, Eduardo; Gandini, Alessandra; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANAIt is worldwide accepted that climate change is affecting cities and that the conservation of the cultural heritage contributes to sustainable development. However, despite the high level of interest and research in climate-change risks on socioeconomic, urban and natural systems, studies that assess climate change impacts on urban cultural heritage and contribute to a holistic understanding on the subject present noticeable gaps in knowledge. A systematic review and meta-analysis was carried out to assess the state-of- the-art of cultural heritage risk assessment methodologies within urban systems in the context of climate change, specifically historic urban areas. For this purpose, a systematic search was applied using Web of Science and Scopus. The search identified and characterized existing methodologies on vulnerability and risk assessment for cultural heritage in a changing climate following the PRISMA protocol, and it synthesized knowledge gaps to be addressed in the near future. This study aims to bring risk assessment methodologies closer to urban planners for more efficient climate change adaptation policies. The research concluded that there is an unbalance between the amount of methodologies for the different climate change derived hazards and their impacts on historic urban areas. The amount of methodologies focused on flooding highlights that further research is needed for other relevant hazards, like heat and cold waves, that contribute to a holistic perspective.Item A holistic and multi-stakeholder methodology for vulnerability assessment of cities to flooding and extreme precipitation events(2020-12) Gandini, Alessandra; Garmendia, Leire; Prieto, Iñaki; Álvarez, Irantzu; San-José, José-Tomás; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANAOver recent years, the frequency and intensity of torrential rain and flooding events linked to climate change have been impacting on cities throughout the world. Adaptation to climate change must therefore be integrated into urban planning and coupled with sustainable urban development and conservation policies. To do so, a good understanding of the vulnerability of cities to these extreme events is necessary, lending special attention to the specifics of the different urban areas, such as historic city centres. In the present study, a vulnerability evaluation methodology is presented for cities against extreme rainfall and flooding, which follows a holistic and multi-stakeholder approach, integrating architectural, socio-economic, and cultural perspectives, that supports evidence-based decision-making for the sustainable development of the agents that intervene in the process. The MIVES method, based on a multiple criteria decision-analysis process and a CityGML-based data model are used for that purpose, with which a process for capturing, evaluating, and representing information in an objective, organized, and systematic way has been developed. These advantages are demonstrated through the application of that process to a case study in Donostia-San Sebastián (northern Spain), located on a river estuary in front of the sea, with a wide diversity of building styles.
