Study Notes

  • Rising sea levels are increasing due to global warming, threatening coastal communities worldwide.
  • By 2050, approximately 300 million coastal residents may experience annual flooding.
  • N-Ark, a Japanese company, has proposed an innovative floating city concept to combat climate change effects.

Dogen City

  • The proposed city will measure roughly 1 mile (1.58 km) in diameter and about 2.5 miles (4 km) in circumference.
  • The circular design aims at protecting against tsunamis.
  • This city will have a two-layer structure:
    • A self-sufficient maritime city on the top layer.
    • An undersea layer houses a sea-cooled data center supporting city management, healthcare, and drug discovery.
  • Dogen City will accommodate 10,000 residents and up to 40,000 visitors.
  • The city aims to be self-sufficient, featuring food production facilities, schools, hospitals, sports areas, offices, and parks.
  • It will use new farming technology to produce up to 7,000 tons of food annually using seawater.
  • State-of-the-art healthcare assessments and medical care will be available to residents and visitors.
  • The plan includes an area for rocket launches and landings for space tourism.
  • The target completion date for Dogen City is set for 2030.
  • Specifics like location and cost are not yet disclosed.

Other Floating City Projects

  • Busan, South Korea, announced similar plans in 2022 for a sustainable maritime metropolis.
  • Busan's floating city seeks at housing up to 100,000 people.

Schoonship, Netherlands

  • The Netherlands has a thriving floating community called Schoonship since 2021.
  • Schoonship consists of 46 homes on 30 water plots, housing around 100 residents.
  • It serves as a small-scale model for self-sufficient, eco-friendly floating cities.
