The Floating ecopolis, otherwise known as the Lilypad, is a model designed by Belgian architect Vincent Callebaut for future climatic refugees. He proposed this model as a long-term solution to rising water level as per the GIEC (Intergovernmental group on the evolution of the climate) forecast. It is a self-sufficient amphibious city and satisfies the four challenges laid down by the OECD (Organisation for Economic Co-operation and Development) in March 2008 namely, climate, biodiversity, water and health.[1]
