Identifying Major Components of Extreme Heatwave Risk Assessment Indexes in Urban Areas

Abstract

Purpose: The risk of urban heatwaves is increasing due to climate change. High temperatures which last for a long periods affects people, society and the environment. The risk assessment herein can play a crucial role in establishing a response plan for urban heatwaves. The factors affecting heatwaves include; size, shape and duration of the heatwaves. The aim of this study is to establish the indicators to be considered for the risk assessment of urban heatwaves and suggest a direction for creation of a basis for risk assessment. Method: In this study, the indicators were assessed through review of previous case studies. Result: Consequently, the evaluation index with the urban scale was created afresh by listing the indicators that could be considered in the heatwaves risk assessment. The indicators are divided into three categories: risk factors, vulnerability factors, and exposure factors. The results of this study enhance the understanding of the heatwaves in different cities and improve the heatwaves risk assessment. Additionally, it suggests a direction for urban planners to develop counter-measures strategy in regards to heatwaves.
