Digitalized Disaster Prevention, Mitigation and Relief Empowering Resilient City Development: A Case Study of Chongqing Heatwave Emergency Management

Abstract

Disaster prevention, mitigation and relief remain long-term challenges for urban governance. Accelerating the development of digital capabilities in disaster risk management is essential for building resilient cities. Taking Chongqing’s heatwave emergency management as a case study, this paper examines how digitalized disaster prevention, mitigation and relief empower resilient city development. The study finds that digital empowerment can effectively enhance urban emergency management capacity through three dimensions: strengthening digital organizational systems, constructing integrated digital platforms, and promoting deep integration of digital technologies. The practice of Chongqing demonstrates that digital transformation enables precise early warning, rapid emergency response, and coordinated disaster management under extreme weather conditions such as heatwaves. This research provides a practical pathway for improving urban resilience through digital governance and offers theoretical implications for the modernization of urban emergency management systems.
