Preparation for various crises such as climate related disasters is necessary for governments of different scales. Local governments, especially city governments, need to play the role of hubs to facilitate the collaboration of stakeholders at local, national, and international levels. In this circumstance, science-based benchmarks for the preparedness of cities for crises are required to assess the status of their policymaking and implementation and its effects. Such benchmarks can identify the potentials and challenges of cities and support the improvement of relevant policies and actions. Considering the needs of the benchmarks, this project develops City Preparedness Index (CPI) based on the collaborations between three countries (Japan, Philippines, and Thailand) which are facing the risks of similar issues such as flooding and urban heat island effect. Those issues are becoming more severe because of the direct and indirect influence of climate change. The project will be implemented with the following two stages; (1) Development and application of CPI to identify key indicators and priority policy topics of cities in terms of preparedness and (2) Network analysis of policy and action which can provide combinations of policies to improve the preparedness of the cities. CPI can contribute to connecting the preparations with policies in various fields such as Eco-DRR, economic and material circulations, and community practices for enhancing long-term urban resilience.
