  • Urbanisation: growth in proportion of a country's population living in urban areas

Urban Areas and Urbanisation

Urbanisation caused by rural-urban migration and naturally increasing populaiton.  Migrants are young people looking for work.  They have children, increasing population.  Takes place because of push and pull factors.

In developing countries: Push:

  • desertification, land cant support population
  • farmers take out loans, crops fail, cant pay back so lose land
  • conflict and civil war, killed or injured - less people wokring so food shortages
  • natural disasters
  • changes in land use
  • mechanisation of agriculture

Pull:

  • more jobs - better pay
  • health and education services
  • family members help find work and homes
  • perception of better quality of life

Urbanisation

Urban population grows; need for space,resources, services increases; if cannot be met, poor quality of life

Developing countries cannot afford extra needs and growth or urbanisation. -ve impacts:

  • not enough houses; live on streets or shelters
  • build own - slums/shanty towns
  • competition for jobs in formal sector, have to accept low wages/poor working conditions
  • informal sector, dangerous
  • pressure on roads and railways, increasing congestion and air pollution

Management

  • new housing to replace slums
  • improving servics in slums
  • residents involved in improving area
  • redeveloping slums into independant townships

Suburbanisation

Push:  housing in city is poor quality - clear low qual housing and build new houses out of city; deindustrialisation - lose jobs - unemployment increases - less money - shops shut

Pull: planning laws more relaxed; improvements in public transport and car ownership; businesses and shops move out of city centre

Impacts on city centre: abandoned, run down;  lower living standards and poverty - unemployment;  people are poorer/foreign = economic and ethnic segregation;  commuting - increased congestion and pollution

Impactss on suburbs: new housing - affects wildlife habitats;  more ground conreted over - increased surfact runoff and risk of flooding;  own cars - cars on road increase = congestion and pollution

Managing impacts: redevelopment schemes encourage moving back, improving brownfield sites; greenbelt to prevent urban areas getting too large - protects countryside; schemes to reduce traffic congestion in city centre; flood defence schemes

Counter-urbanisation

Push: escape air and noise pollution; cities have congestion and problems parking; house prices rise, not getting value for money

Pull: housing developments less densely packed; quieter and open space; improve quality of life; improved communication services = work from home; technological improvements = companies move to rural; increased jobs; increased car ownership; increased rail services; commute to work

Impacts on rural areas

Positive: increase in business; residents have higher disposable income; farmers make money selling unwanted land/buildings; schools in rural areas can stay open

Negative: developments unattractive; rural shops and services shut (wealthy residents have cars); roads and infrastructure cant cope with extra traffic; schools close if residents dont have kids; house prices increase = old population

Manage: developments allowed if similar to current buildings; companies offer mobile services (banks); local occupancy clauses

Re-urbanisation

Pull: redevelopment of brownfield sites (new developments); urban development corporations = buy land and plan how to use to encourage businesses and people to move back; universities; young single people want to live close to work with good clubs; once it has started it continues

1. Decline in industry - movement of manufacturing oversees, sites outside city centre

2. Increase in unemployment - industry decline = job loss, people move away for work - jobs unskilled/low paid

3. Shops and services decline - fewer people ot use shops, remaining have less money, shops close down

4. Physical environment declines - empty buildings = derelict = vandalism and grafitti, parks neglected = crime, becomes unattractive = more decline

Gentrification - regeneration by wealthier group

+ves: housing improved; value of housing increases; new businesses = jobs; crime rates fall

-ves: high demand for housing = tennants forced out - landlords sell for money; children of original homeowners unable to buy/rent; original shops/services replaced by upmarket shops; tension between old and new
