Item Climate change risk assessment: A holistic multi-stakeholder methodology for the sustainable development of cities: A holistic multi-stakeholder methodology for the sustainable development of cities(2021-02) Gandini, Alessandra; Quesada, Laura; Prieto, Iñaki; Garmendia, Leire; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANACities are at risk due to global climate change, increasing both the frequency and the intensity of storms and extreme precipitation, sea-level rise, and other extreme weather events. Disaster risk reduction and adaptation to climate change should include a holistic and multi-scale perspective, to address the challenges of sustainable urban development and the conservation of the cultural value of our cities. In this research, an integral multi-stakeholder methodological approach is presented for risk assessment, supported by a data-collection and analysis strategy and a multi-scale urban model based on CityGML. A method of sampling buildings is presented together with the necessary data analysis, in order to perform the analysis at city scale. The methodology is implemented in Donostia- San Sebastián (northern Spain), a city located alongside a river estuary on the coastline. A sample of 2262 buildings are analyzed with varied characteristics at risk of extreme precipitation and/or storm surges and sea-level rise. The results demonstrated the effectiveness of the methodology at generating a unique risk index through a balance between the resources for data collection and the accuracy of the results, supported by a graphical 3D representation to facilitate results interpretation, and the subsequent evidence-based decision-making for prioritizing sustainable interventions.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.
