Is it a possibility that megacities are too big and fast moving to foster any kind of community?
Megacities that house populations over 10 million people, such as Tokyo, Shanghai, Jakarta, Delhi, Seoul, Sao Paulo, Lagos, London, New York, are in a constant state of flux. People, businesses and trends come and go at an astonishing rate. It could be argued, based on homo-sapiens inclination to form small communities in the wild natural world, that these populations are just too large to foster any meaningful feeling of community spirit.
Arguably nothing can be done to artificially foster this feeling in these massive urban environments. With this in mind, people that complain about gentrification are the people that are being left behind and seeing their once more quiet, slightly more isolated area, being swallowed up by the urban landscape. This development is far more complex and bigger than some individuals can cope with financially or socially, as the situation really becomes a question of the urban landscape changing to a degree more than what most individuals are comfortable with.
Tokyo, the world’s largest and most heavily populated urban area, is a good example. Here the urban areas go through 30 year redevelopment cycles, buildings usually being removed and completely rebuilt rather than regenerated or preserved in any way. However, this often takes the form of top down regeneration that comes from more of an urban redevelopment approach, but as a result areas are constantly changing. This coupled with a great transport infrastructure means that the area you live in is less of a problem, and individuals choose to live is less of an issue, making moving also less of an issue, and meaning any community is too short lived to really take hold in an area. The result of all this is that the city stays modern on the whole and people are happy to move around and cope with change a lot more effectively.
