  5. 5. Urban Processes a) Urban growth – physical growth of cities. b) Urban Sprawl – uncontrollable growth of cities into surrounding rural land. c) Suburbanisation (LEDC cities) – when wealthy live often in gated communities to escape crime, poverty and pollution from the CBD. Common in South Africa. d) Counter Urbanisation (MEDC cities) – movement of people out of city to rural area. e) Reurbanisation (MEDC cities) – Attempts to regenerate cities, especially in Asian cities.

  16. 16. Reasons for the growth of London suburbs 1. Transport For suburbs to develop excellent transport networks are needed. The underground, overland trains, buses and now even bike hire means that it is easy to get from the suburbs into the city centre. In London the average commute is 40mins. Video here 2.
