Abstract:
Worldwide urbanization has resulted in the creation of so called “megacities” with populations of 10 million or more. It is estimated that 68% of the world’s population will reside in urban centers by the year 2050 up from 55% in 2018 [1]. This pace of urbanization is staggering, especially in China where urban populations have more than doubled over the last 30 years, while urban land extent has more than tripled [2]. Today, urban planners and engineers are faced with challenging decisions regarding land management planning. To manage this population increase, there is a need to cultivate urban underground space to reduce congestion on the surface, control urban sprawl, and provide opportunities to re-purpose land for recreational space. This discussion paper provides a review of several recommended practices for urban underground space development addressing planning, intended function, and environmental sustainability/resiliency.
