More than half of the world's population now lives in urban regions, mostly in cities. The vulnerability of these cities has significantly increased due to the complexity of new challenges, which range from economic to social to ecological. According to several studies, ongoing stressors and unexpected hazards can worsen social breakdown, economic hardship, and even cause physical collapse. Even though many cities have endured for centuries, the more recent emergence of urban-related stresses and shocks, such as climate change, major natural disasters, diverse complicated conflicts, and a lack of natural resources, is causing a need for more resilience than ever before. When populations are subjected to hazards and stressors, they may become a risk, and when infrastructure, buildings and communities lack the resilience to deal with, adapt to, and recover from their effects, they may become "vulnerable." Therefore, it is plainly evident that urban environments and communities, including the architecture of cities, must become more resilient and sustainable.
