Strategies for Maintenance and Resilience of Aging Critical Infrastructure in the Climate Crisis Era

In 2002, with the publication of Human Geography in Nature magazine, Paul Jozef Crutzen proposed the concept of “Anthropocene” in his article. The core of the concept of “Anthropocene” is that the current impact of human activities on the earth far exceeds the impact of natural changes. Since the beginning of the Industrial Revolution, human society has gradually invaded and changed the ecological balance of the earth through landform transformation, land use, mineral mining, surface and groundwater extraction, etc. At the same time, “climate”, one of the attributes of the earth, has also gradually undergone irreversible changes. These changes eventually formed the “global climate crisis” we know now. The process of mutual influence can be explained by the “Mobius Strip Theory”, that is, humans and the earth's ecology and natural environment are interdependent and influence each other. All influences will act on the time process and gradually expand as time goes by. Eventually, like a boomerang, it will act on human society. This “evil influence” and “global disaster” will once again trigger changes in the infrastructure and living environment of human society, as well as disaster avoidance patterns. “Critical infrastructure” is the core component of the “urban lifeline” that human survival depends on. In the current global climate crisis disaster, the degree of loss and wear rate continues to rise, so that it enters the “middle-late stage” of its life cycle too early, which will lead to the inability to provide equivalent disaster resistance and shelter capabilities when facing climate disasters that cannot be accurately predicted. At the same time, this process will affect the entire disaster emergency response system, and the city will inevitably be in a state of chaos. This study will focus on providing timely maintenance and protection strategies for aging critical infrastructure under the global climate crisis. The process is not limited to mechanical structures. The research scope is expanded to maintenance model description, maintenance system analysis, etc., and from the perspective of crisis management scholars, maintenance suggestions are provided for the stability of urban lifeline structures.
