To accommodate rapid population growth, coastal city dwellers create mounds of sand in the ocean, on which they erect new buildings. Such projects often destroy fragile marine habitats and can be partially submerged within a decade due to rapidly rising water levels. The modular design of the Oceanix floating city solves both problems, Elle.ru reports[49].

"Sustainable floating cities are a part of the arsenal of climate adaptation strategies available to us. Instead of fighting with water, let us learn to live in harmony with it. We look forward to developing climate adaptation and nature-based solutions through the floating city concept, and Busan is the ideal choice to deploy the prototype," said the Executive Director of UN-Habitat, Maimunah Mohd Sharif[50].

As stated on the project website, the city will span over 6 hectares and provide accommodation to 12 thousand people. The city will be built on top of three platforms connected by bridges. Each platform will serve a specific purpose — lodging (eco-hotels), research, and living. Each platform area is 30,000 to 40,000 square meters[51].

The city will have integrated systems for generating electricity, reducing waste and recycling resources, and providing a comfortable temperature for growing various crops.

"9 out of 10 of the world’s largest cities will be exposed to rising seas by 2050. The sea is our fate — it may also be our future," says Bjarke Ingels, founding partner of BIG.

The first modular maritime metropolis is planned to be built by 2025.

WOVEN CITY

COUNTRY — Japan

In 2020, Toyota announced that it would build a city of the future at the foot of Mount Fuji.

It is being designed by the Danish architect Bjarke Ingels.

The city is expected to be completely environmentally friendly, with buildings made mainly of wood, following the style of Japanese wooden architecture combined with robotic production methods. The roofs will be covered with photovoltaic panels to harvest solar energy in addition to the electricity produced by hydrogen fuel cells. The houses will be fitted with smart technology and artificial intelligence.

Only fully autonomous, zero-emission vehicles will be allowed to move residents around the city on major thoroughfares, according to a press release from Toyota[52].

"Building a complete city from the ground up is a unique opportunity to develop future technologies, including a digital operating system for the city’s infrastructure," said Akio Toyoda, president, Toyota Motor Corporation.

AKON CITY

COUNTRY — Senegal

Back in 2018, rapper and businessman Akon Thiam took it upon himself to build an African city of the future. He was inspired by Wakanda, the fictional African country from the Marvel Comics superhero movie Black Panther.

Akon comes from Senegal. Several years ago he was donated 800 hectares of land by Senegalese President Macky Sall. According to the rapper, the city should become the world center of ecotourism.

Akon City will be solar-powered. The city will be surrounded by artificial islands and eco-resorts. Inside, there will be a port for cruise ships, skyscrapers with apartments and business centers, shopping centers, condominiums, a hospital and a university. The city will even have its own cryptocurrency — Akoin, according to RBC[53].

The city is expected to be completed by 2025.

TENGA

COUNTRY — Singapore

Singapore is building an eco ‘smart’ city of the future. The project is being implemented by the Housing & Development Board of Singapore. Giant solar-powered air conditioners, vacuum waste collection, underground roads for electric cars, urban farms, and lots of green spaces — this is what the country’s most ambitious project will look like.

According to studies, the average temperature in the tropics is about 27 degrees Celsius.

The amount of electricity needed for cooling in Singapore is projected to increase by 73 % between 2010 and 2030.

In the new city, air conditioners will be solar-powered and installed on the roofs of residential buildings. This will cut energy consumption by 30 % — this will generate emission savings equivalent to taking 4,500 cars off the roads each year, Bloomberg reported[54].

Each of the 42,000 apartments will be equipped with a smart control panel that will allow homeowners to control their energy consumption. Railroads, driveways, and parking lots will be moved underground for most part, making room for gardens, urban farms, and walking and biking. Houses will also have a system for vacuum garbage collection via underground pipes. A gasification plant will turn garbage into energy — a more efficient way to produce fuel than incineration.

"Developments like this, in addition to efficient design of amenities, will have a far greater effect on reducing long-term carbon footprint than the actual greenery," said Lahiru Wijedasa, co-principal investigator and senior research fellow at the National University of Singapore’s Environmental Research Institute in an interview to Bloomberg.

MASDAR CITY

COUNTRY — UAE

A city of the future in the middle of the desert is a project launched back in 2006, but the construction ran into a number of problems since then. The works are scheduled to be completed by 2030.

According to the project website, Masdar City is a sustainability pioneer and research and development center[55]. The city is located near the Abu Dhabi airport. It combines traditional Arabic architecture with modern technology and design. Buildings made of eco-friendly materials are designed to cut water and energy consumption by 40 %.

Residential areas, business center, parks, pedestrian zones, manned and unmanned electric vehicle parks will make the city accessible to all.
