In recent years, cities have been confronted with increasing risks induced by climate change and natural hazards impacts. The experience gained highlights how cascading failures of critical infrastructures and basic services can affect both inherent and adaptive capacities of cities in time of an adverse event and create post disaster conflicts. At the same time, international policy circles have acknowledged the need to have sufficiently consistent and comparable disaster-related data to allow meaningful measurement of progress and impact. Therefore, to serve this need, understanding the link between resilience qualities of critical infrastructures and Open Data can lead to increase the level of disaster resilience, preparedness and response. It can also influence future-oriented urban and infrastructural planning at the local level. This paper offers a theoretical framework for building resilience in basic infrastructures and services across disaster preparedness and response concerning the contribution of Open Data for climate and natural hazard risk management in Tehran, Iran.
