1 . The global sea level has risen by eight to nine inches since 1880. What’s more disturbing is that one-third of the rise in sea level happened in the last 25 years. Rising sea levels pose an existential threat for some small islands and some low-lying coasts. In a response to this threat, UN-Habitat, the Busan Metropolitan City of the Republic of Korea, and the company OCEANIX revealed the world’s first model floating city, OCEANIX Busan.

OCEANIX Busan has six integrated systems focusing on energy, food, water, waste, mobility and coastal habitat regeneration to ensure the floating city reuses and wastes as little as possible. The floating city has no roadways, only “pedestrian-friendly paths” to support walking, biking, and autonomous electric vehicles, so it won’t produce any vehicle emissions. Floating and rooftop photovoltaic panels(光伏板)will generate 100% of the operational energy needed for the city. Each neighborhood will treat and replenish(重新补充)its own water, recycle resources, and have urban farm areas to grow food.

OCEANIX Busan will consist of three floating neighborhoods totaling 15.5 acres. That’s about as much surface as a dozen football fields, and according to the developers, it has enough room to accommodate 12,000 people. The neighborhoods will connect to one another and the mainland via bridges, and each will serve a specific purpose. The living neighborhood will have residential buildings, shops and food sellers, and a “community backyard” where residents can gather at its center. The lodging neighborhood will be built to support visitors-it’ll have many shopping and dining options, as well as guest rooms designed to maximize ocean views. The third neighborhood will be a co-working and research center, with a temperature-controlled atrium(中厅)at its center for hydroponic agriculture.

“Today is an important milestone for all coastal cities and island nations on the frontlines of climate change. We are on track to delivering OCEANIX Busan and demonstrating that floating infrastructure can create new land for coastal cities looking for sustainable ways to expand onto the ocean, while adapting to sea-level rise,” said Philipp Hofmann, CEO of OCEANIX.
