This paper describes methodologies for assessing risk at conurbation and neighbourhood scales that have been developed in order to provide urban planners with a toolkit for the assessment of risk due to climatic hazards. The methodologies treat risk as a function of hazard, vulnerability and exposure, all three of which elements are influenced by climate change. These three elements are represented as geospatial data layers in a geographical information system (GIS), in order to provide a logical framework to assist planning and management for communities that are safer, more sustainable and more resilient in the face of climate change. The risk assessment methodologies have initially been developed and applied at two different scales: a conurbation scale, using a screening process to locate areas of high risk to assist with land use planning tasks, and a neighbourhood scale, focusing on the influence of the vulnerability of the building stock on this risk. However, using the two methodologies in tandem can refine the assessment further, so the potential development and application of a combined methodology is explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
