In Lagos, Nigeria, one of the world's largest cities and one which is very prone to damages from rising seas, the swampy economically deprived community of Makoko, a floating community school has been built in anticipation that land based buildings may be in jeopardy in the future. Images of the school show an A-framed wooden building atop a barge like platform.
The architect is Kunle Adeyemi and he proposes that this may be a model for other at risk cities. His idea is gaining attention as storms ravage east coast cities this last year like New York and Boston as mentioned in this article. Maybe we can extend this idea to include floating gardens and crops. This could help preserve precious land resources and prevent overuse. Some thought leaders have already conceptualized floating cities and near shore based urban buildings in which people live and work and which also have large urban gardens supporting the off-shore community.
Whether its changing climates, land overuse, or diminishing resources to supporting land based mega-population centers, evaluating near-shore platform cities may lead to acceptable living options in the future.
