Underground spaces of cities have a hidden capacity for sustainable urban development

One way to deal with urban problems is to use subsurface spaces. Subsurface spaces have received more attention in recent years due to protection against adverse conditions, environmental protection, increased transport system efficiency and economic efficiency. Underground spaces can be an effective means of achieving sustainability Unlike the prevailing notion, underground spaces can be used in recreational (sports, parks, etc.), commercial and office applications (markets, libraries, etc.). , Cultural (museum, cultural, cinema) and services (parking spaces). That is, subsurface spaces can. Underground development is a potential potential that, if managed properly, can also contribute to sustainable development while addressing new needs and helping urban management. The purpose of this paper is to focus on the subsurface space as the missing link of urban management in achieving sustainable urban development. The research method is descriptive-analytical and research literature has used documentary-library sources and internal and external sources. The results show that subsurface spaces can help solve many urban problems and lead to urban sustainability and sustainable development as a long-term goal of cities. Sustainable urban development with the approach of using underground spaces is one of the new approaches in urban planning. While taking advantage of the positive capabilities of subsurface spaces, this approach seeks to address urban problems such as space shortages and environmental issues.
