Around the world, people and societies are at risk of being affected by disasters, both natural and man-made. In the face of climate change and human activity, the threat posed by unexpected disasters is likely to increase in future. This book, the first of its kind in Hong Kong, offers insights from experts in healthcare and higher education both locally and further afield. Some of the authors have first-hand experience with various elements of disaster management through such events as the 2008 earthquake in Sichuan, the COVID-19 pandemic, and large-scale competitions including the Standard Chartered Hong Kong Marathon. Key learnings and recommendations are presented in three sections: disaster management and reconstruction, including what we can learn from past earthquakes; the importance of healthcare and emergency medicine in disasters and community events; and the way forward, in particular how technology and systems thinking can be used for disaster mitigation.
