Cycle of urbanisation
Urbanisation → suburbanisation → counter-urbanisation → re-urbanisation
All happening in different parts of a city
Urbanisation
a process of change whereby places and people become increasingly urban. 50% world urbanised
Urbanisation characteristics
change in economy, population, size, character, environment and lifestyle of settlements
Causes of urbanisation
- Rural - urban migration (young)
- Natural increase
PUSH FACTORS
- Human activity and climate change - desertification
- Crop failure
- Conflict
- Natural disasters
- Change in landuse
- Fewer people needed to work on farm - less jobs
PULL FACTORS
- More employment
- Better paid jobs
- Better access to health and eductaion
- Family
- Perceived better quality of life
Impacts of urbanisation
- Not enough housing/expensive - increased demand for space, poor quality of life
- Slums - poorly built, landslide/flood risk, lack of basic services, high risk of disease, little access to education → cycle of poverty
- Infomal work, mistreating, low wages, poor conditions, little job security, dangerous
- Congestion and air pollution
Management of urbanisation
- New houses to replace slums
- Improving slum services
- Get residents involved in local areas
- Redevloping areas of slum into independent townships
- Difficult due to scale of problem
Urbanisation case study 1: Mumbai → charactersitics and causes of urbanisation
- West coast of India
- Currently population over 20 million
- India’s largest city
- Population desnity of 21800/km2
- Low taxes to encourage investment
- Grew due to outsourcing of large western companies eg BT, port, manufacturing etc.
- Growth problem due to peninsula
- Split of rich (uni, towers, stocks, bollywood) and poor (informal housing, 1500 single room factories, over 1000 migrants per day)
Urbanisation case study 1: Mumbai → consequences
Dharavi - biggest slum in Asia - 1 million in 2km2
- Up to 20 people per house
- Open sewers - diptheria, typhoid and TB → 4000 cases each day
- Sanitation poor - washing in contaminated water
- Rubbish and rats
- Strong sense of community
- 15000 1 roomed factories making $1billion a year
- High employment - cottage inductries eg soap, tanneries, potteries
- Industry unregulated and illegal - cheap labour
- Appalling work conditions - children as young as 12
- Sort recycling with no protective clothong for less than £1 a day
- e.g. Kumbharwada potters colony - 10000 live and work
Urbanisation case study 1: Mumabi → solutions
- Buldoze slums and build 7-storey apartment blocks
- Safer and healthier
- Business has room to expand
- Better standard of living and infrastructure
- Less of an eyesore - tourism
- Proper drainage
- Not everyone entitled to a tennament - slums
- Loss of jobs, business and community
- Focus on money and profits, not people
- Crowded living spaces
- Long time
- Outdoor spaces neglected
- Temporary housing needed in the process
- Self-help schemes - LAs to provide basic building material to help improve homes→ electricity, water and sanitation
- Maintain infrastructure themselves
- Cleaner, healthier and safer
- Improved community, same homes
- Residents involved - cheaper
- Won’t take as long
- People don’t have the skills to build - teaching needed
- $11 billion economy not expanding
- Eyesore
- Some won’t get involved → new migrants everyday
Urbanisation case study 2: Bangalore → causes and characterstics
- Centre of new technology, banking, finance and new economy.
- 40% India’s 1.3 million workers in IT industry based here
- 1990 economy liberalised and allowed overseas companies to locate - employment and population rose rapidly
- Tradiational values found alongside urban growth
- 1996 BA set up account operations in Bangalore - set off outsourcing trend in Bangalore. Wages 10% those in London.
- Bangalore university provides a highly educated workforce - highest incomes in India
- Increase in affluence, new shops, bars, cafes → 6 new malls, large investment banks
- Develop out of town business parks
*
Urbanisation case study 2: Bangalore → Problems
- Rich/poor caste system - low caste Dalits reomve human excrement from pits
- Poor see few benefits of economic boom
- Only highly skilled and educated gain jobs
- Increased population puts more pressure on housing and services
- Dalit children sit at the back of classrooms, prohiting education
- Exploitation of cheap labour
- 1/4 population in slums
- Rents beyond workers on average pay
- Air/noise pollution
- Only 1/3 of 3000 tonnes waste collected
- Contaminated water
- Farming soils less fertiles due to pressure
Urbanisation case study 2: Bangalore → Solutions
- Internationsla airport enlarged
- Develop energy provision - provate generators needed due to power failures
- Improve public transport - 5 million vehicles clog roads
- Build more housing with lower prices
Suburbanisation
The movement of people from living in the inner parts of a city to living on the outer edges
Suburbanisation causes
PUSH
- Congestion
- Pollution
- Low quality of life
- High land prices
- Decrease in employment
- Poor services
- Crowded - saftey questionable
PULL
- Open space
- Lower land prices
- Job opportunities
- Transport provides access to city
- Safer
- Lower desnity housing
- Better services

Effects of suburbanisation
- Edge cities - office builiding built around suburban business districts and malls
- Traffic congestion
- Donut cities - economic activities into suburbs
- Urban sprawl - green belt policies
- Urban redeclopmnet
- Urban smog
- Social segreagtion
Suburbanisation case study 1: Los Angeles → Cuases of growth
- Transport - transcontinental railway 1876, 1/2 million within 40 years, LAX 2010 6th busiest
- Employment - oil, ford etc.
- Image - film industry in Hollywood 1920s, 1960s Disneyland and Universal
- Great affluence - choice, 60s/70s fastest population growth, sun belt of California
Suburbanisation case study 1: Los Angeles → Problems
- Suburbanisation
- 14 million
- Better quality of life
- Transport - electric tram 20s/30s can live further away from work, freeways allow driving into CBD, 1980s petrol cheap → less than $1 per gallon, 1980s as far as San Bernadino - 2 hours
- LA declined
- Dormitary settlements
- Urban smog
- 10 million car owners

- Cause health hazards eg asthma
- Poor public transport - 2005 10.2% used compared to 40% in LOndon. 1.7 millioj journeys a day
- Donut cities and edge cities
- Long established car factories closed due to competition from overseas
- Businessed follwed people out - more space, cheaper land, lower tax
- Umemployment in inner city and dereliction
- Edge cities e.g. Ontario developing freeways - little contact with city
- Social segregation
- Deprived in centre, wealthy in suburbs
- High income in small clusters
- Ethnic enclaves
- Other
- Water - piped from 350km away - 50% evaporated before reaching city
- Water - 50000 tonnes produced per day - despost scheme 25% refund for container
- Energy - air con, over 45oC 2010 blackouts

Countwe urbanisation
The migration of people from major urban areas to smaller towns, villages or rual areas - often leapforgging the green belt
