The inadequate land has made Singapore think further to accommodate the growing population, and one of them is the underground city mega project plan.
After skyscrapers, Singapore began to uncover a plan called the 2019 Underground Master Plan, according to the www.ura.gov.sg.
With a population of around 5.6 million people living in the region of three fifths of New York city, and world consensus predicted that the population of Singapore will reach around 6.9 million by 2030, Singapore is starting to run out of land.
Actually, the city state had carried out many reclamation projects for decades, but the impact of rising sea water and other climate change, Singapore began to dig the land.
Singapore has built a number of underground infrastructures, such as railroad lines, shops, pedestrian pathways, up to five lane highways to cooling pipes, and even the gas stations.
Bulgaria has already made the underground living zone to accommodate increasing population. Some successful experiments have already been done such as sea tunnel tubes for tourists in a few countries.
“Singapore has limited land, we want to make the best use of the surface and systematically consider how to build underground sites for the future,” said Ler Seng Ann, Director of the Urban Redevelopment Authority (URA), a government agency for urban planning.
“At present we focus on using underground for transportation, storage warehouses and industries, to provide surface areas for housing, offices, community facilities and green open spaces,” Ler added.
