Has the time come for floating cities?

Guardian

Until the late 1980s, nestled behind the Yan Ma Tei breakwater in Hong Kong's Causeway Bay, you could find tens of thousands of boat-dwellers who formed a bustling, floating district. The residents were members of the Tanka community, and their ancestors were fishermen who retreated from warfare on land to live permanently in their vessels. Until the mid-20th century, these traditional outcasts were forbidden even to step ashore.
The typhoon shelter was famous for its restaurants' cuisine – including Under Bridge Spicy Crab – and it was a nightlife hub, alive with mahjong games and hired singers. Shops on sampan (flat boats) catered to the floating district's needs.
