Parameter Based Assessment Model for Measuring Climate Risk of Cities

A methodology for assessing vulnerability and risk at the urban scale was developed and tested in this study. This facilitates the development of climate change adaptation measures and strategies by planners, designers, and decision -makers at the urban level and guides their decision -making processes. The methodology combines spatial information based on a 100x100m grid with indicators such as exposure, vulnerability and adaptive capacity to determine the level of risk by defining and weighting spatial information as indicators and produces a risk result through multi -criteria decision -making. In this scope, physical parameters affecting the risk level were determined according to the heat wave and heavy rainfall hazards, which are the two prominent hazards in urban areas for vulnerability and risk analysis. These parameters were included in the analysis as artificial surface ratio, presence of trees, population density, building density, wind and street direction, storey height, building facade colors, presence of flood risk, building construction year -building age, roof type and building material. The methodology was then tested on the urban fabric of Erzurum. The results show that different risk values correspond to different typologies of urban areas and provide areas for immediate intervention. The sensitive spatial information provided by indicators and land use categories is of great importance to support adaptation to climate hazards.
