An integrated computational and collaborative approach for city resilience planning

Given the rise in climate change-related extreme events, there is an urgent need for cities and regions to implement resilience plans based on data and evidence and developed in collaboration with key stakeholders. However, current planning and decision-making processes rely on limited data and modelling. Moreover, stakeholder engagement is significantly inhibited by social, political, and technological barriers. The research presented in this thesis aims to enhance resilience planning practice through the development and evaluation of an integrated computational and collaborative scenario planning approach. The scenario planning approach is tested within a geodesign framework and supported by several planning support systems (PSS), including urban growth models. These PSS tools are made accessible to key stakeholders through dedicated planning support theatres, enabling participants to collaborate both in-person and online. Through two empirical case studies conducted in Australian regions, this research integrates data-driven modelling (computational) with people-led geodesign (collaborative) approaches for scenario forecasting and planning. The first case study explores anticipatory/normative scenarios, while the second focuses on exploratory scenario planning, with both aiming to enhance city and regional resilience. This thesis examines the roles played by both simple digital tools and purpose-built planning support theatres in scenario planning processes with key stakeholders. The research investigates the utility of data-driven models in supporting collaborative scenario planning. Both integration experiments received positive feedback from most participants. However, to truly improve the process, there is a need for widely available high-quality spatial and temporal datasets, including localised climate change impact data. In summary, an integrated computational and collaborative approach, augmented by data and technology, can provide an evidence base for decision-making towards a resilient future, fostering deeper engagement of the local community and across-government collaboration in scenario planning.
