Following the forecasts of GIEC (Intergovernmental group on the evolution of the climate), the ocean level should rise from 20 to 90 centimeters during the 21st Century. This would lead to significant ground losses for a number of countries, with a lot of people that are expected to be displaced from their homes.
Paris-based architectural practice Vincent Callebaut Architectures proposed a concept of a self-sufficient amphibious city for the year 2100 that will provide shelter for the future climate change refugees. Titled Lilypad, the city will travel across oceans, from the equator to the poles, following the sea streams.
It is a true amphibian half aquatic and half terrestrial city, able to accommodate 50,000 inhabitants and inviting the biodiversity to develop its fauna and flora around a central lagoon of soft water collecting and purifying the rain waters. This artificial lagoon is entirely immersed ballasting thus the city. It enables to live in the heart of the subaquatic depths. The multifunctional programming is based on three marinas and three mountains dedicated respectively to the work, the shops and the entertainments. The whole set is covered by a stratum of planted housing in suspended gardens and crossed by a network of streets and alleyways with organic outline. The goal is to create a harmonious coexistence of the couple Human / Nature and to explore new modes of living the sea by building with fluidity collective spaces in proximity, overwhelming spaces of social inclusion suitable to the meeting of all the inhabitants – denizen or foreign-born, recent or old, young or aged people.
