Ever since mankind first appeared on Earth, people have confronted a variety of threats caused by global environmental changes and catastrophic natural disasters. In recent years, there has been a huge necessity to attempt the complementary co-evolution among technologies, urban management, and policy design by putting greater emphasis on local orientation while fully utilizing academic traditions of civil engineering, architecture, environmental engineering and disaster prevention research. This book seeks to meet the challenge of defining the new concept "human security engineering" via the implementation of such applicable technologies in Asian megacities.
