Q

What does the process of urbanisation involve?

A
  1. Rural to urban migration - mass movement of people from countryside to city
  2. Industrialisation- the growth of industry (UK Industrial Revolution from 1760-1840)
  3. Improvements in transport followed - trains/ cars developed quickly
    . Happened hundreds of years ago in HICS but now happening in LICS

22
Q

A

. A metropolitan area with total population over 10 million people
. There are 38 global megacities

23
Q

24
Q

What is happening to the world’s megacities?

A

. Asian cities growing most rapidly e.g Guangzhou growing by 5.2% , Beijing 4.6%
. African cities beginning to grow slowly too e.g Lagos 3.9%, Kinshasa 4.2%
. Europe, North and South America aren’t growing that quickly in their megacities

25
Q

What factors have caused growth of megacities?

A
  1. Rural to urban migration - lack of jobs in countryside. Overpopulation+ poor crop yields = push factors to leave countryside
    . Better jobs in cities and more reliable food+ higher living standards = pull factors
  2. Natural increase- people who migrate to cities have children due to better medical conditions and more successful births
26
Q

What is a world city?

Cities which are seen to have an important role in the global economic system

27
Q

What are world cities categorised into and what are some examples?

A

. Categorised into Alpha, beta and gamma
. Alpha cities are most important and categorised into alpha ++, alpha+, alpha and alpha -
. Alpha ++ = most important
. Alpha++ London, New York
. Alpha+ Hong Kong, Paris, Tokyo
. Alpha Johannesburg, Moscow, Mexico City

28
Q

  2. Status
  3. Power
    . Economic e.g TNC’s, equity market, international banking and stock exchange
  4. Influence
    . Political e.g government ambitions, democratic government
    . Cultural e.g rich heritage, universities, arts and entertainment
29
Q

What are the causes of urban growth?

A
  1. Natural increase- the difference between birth and death rate
    . Urban areas tend to have a higher percentage of younger people
  2. Rural to urban migration- the movement of people from countryside to city
    . Migrate due to push factors in countryside and pull factors in the city
30
Q

The ‘Nappy Valley’ as there are so many young families

31
Q

  4. Agricultural problems including desertification
  5. Agriculture being organised globally
32
Q

  2. Employment in factories and service industries
  3. Better quality of life
  4. Better quality social provisions
  5. Better education opportunities
33
Q

What are some positive impacts of urbanisation?

A
  1. Better public transport
  2. Lower unemployment rates
  3. Better overall infrastructure
  4. More education opportunities
  5. Easier to socialise
34
Q

A
  1. Littering
  2. Higher level of air pollution
  3. Traffic jams
  4. Development of slums
  5. Lack of natural spaces
35
Q

What are the consequences of urban growth?

A
  1. Urban sprawl - spread of urban area into surrounding countryside
    . Loss of open spaces + increase fossil fuel consumption due to commuting
  2. Shortage of housing in LIC’s
    . Population density increase = shortage in housing+ lack of basic essentials
  3. Shortages of affordable housing in HIC’s- in Uk increase house demand= increase in house price + rental costs
    . Houses prices rose by 50% between 2010-2015
  4. Lack of urban services and waste disposal
    . Financial restraints= lack of basic services + maintenance of infrastructure limited
  5. Unemployment and underemployment - so many young people = pressure to create jobs
    . Underemployment = person not doing work that makes use of their skills + abilities
  6. Transport issues- urbanisation + suburbanisation led to increased traffic across world
    . Increased congestion+ pollution damaging the environment and human health
36
Q

What are the 3 main contemporary urban processes that occur in HIC cities?

A
  1. Suburbanisation (urban sprawl)
  2. Counter-urbanisation ( go into surrounding villages)
  3. Urban resurgence?? (Going back into cities)
37
Q

What is suburbanisation?

A

The increased movement of people/services and industries from the centres of inner urban areas outwards, towards and onto the edges of the built up area

38
Q

When did suburbanisation begin in the UK?

A

. Suburbs continued to grow rapidly in all British cities in the inter and post war periods
. During this period were fewer planning regulations+ urban growth took form of ribbon development along main routes
. 1800-1900 very rapid urban industrialisation
. Industry could pay most for city centre cities
. Unplanned housing develop around factories
. Middle class began to move in suburbs= most known as ‘white flight’

39
Q

What are the causes of suburbanisation?

A
  1. Decentralisation
    . Shift of jobs into service sector
    . Non centralised locations = cheaper land
    . Many service industries located in suburbs
  2. De-industrialisation
    . Loss of manufacturing jobs in inner cities
    . Inner cities experience spiral of problems e.g unemployment, deprivation
    . Workers often lacked skills for jobs in service sectors
  3. Attractions of edge of city location
    . Green space
    . Cheaper land
    . More pleasant environment
  4. Technology
    . Can commute longer distances
    . ICT and communication developments = people can work from home
40
Q

What are some positive effects of suburbanisation?

A
  1. Development of brownfield sites
  2. Gentrification of certain areas
  3. Green belt policies in place
  4. Development of science parks, shopping malls e.t.c
41
Q

What are some negative effects of suburbanisation?

A
  1. Infilling of houses and buildings in open spaces
  2. Traffic congestion increase
  3. Segregated city ‘WHITE FLIGHT’
  4. Cost of land cheaper in suburbs so people want to do live in the suburbs instead of in the city
42
Q

What is counter-urbanisation?

A

Movement of people from urban areas into rural areas surrounding the city ( beyond green belt)

43
Q

Who does counter-urbanisation?

A

. Most affluent and mobile people
. Families with children ( keen to avoid inner city issues)

44
Q

What are the push factors for counter-urbanisation?

A
  1. Traffic congestion
  2. Pollution
  3. Fear of crime (burglary, theft e.t.c)
45
Q

What are the pull factors for counter-urbanisation?

A
  1. Rural dream
  2. Improved transport
  3. Estate agents, housing developers e.t.c (encourage outward movement)
46
Q

What factors have helped counter-urbanisation?

A
  1. Technological change - Emails,+ phones = teleworking and working at home
  2. Freezers, telephone TV e.t.c- allow rural lifestyle but not isolation
  3. Improvements in transport- commuting easier from rural to urban areas
  4. Urban renewal process during 50’s and 60’s- rehoused council estate estates on edge of the city in New Town/ overspill settlements
47
Q

What are the steps of counter-urbanisation?

A
  1. Individual new homes (barns converted into homes) built on vacant land in village
  2. Ribbon development of more homes along main roads
  3. Land between roads entering village is infilled with larger housing developments- many occupied by people from nearby towns and cities hoping to find balance between rural and urban lifestyle
48
Q

What may be the differences between a normal village and a suburban village?

A
  1. Social- small close knit community ➡️ ‘dormitory village’ + resent,ent of new arrivals
  2. Inhabitants- primary jobs e.g farming, manual labour jobs+ working locally ➡️ professionals, executives, often wealthy middle class families or retired
  3. Transport- limited cars, rural bus service ➡️ declining bus service, congestion, improved roads
  4. Environment- quiet, relatively pollution free + green spaces ➡️ more noise and pollution+ loss of open space and farmland
49
Q

What is urban resurgence?

A

. Movement of people back to live in old inner city areas which have been redeveloped

50
Q

What are the 2 processes of urban resurgence?

A
  1. In-movement by individuals or groups of upper middle class white individuals, into older hosing which is improved- GENTRIFICATION
  2. In- movement of people as part of large scale investment programmes aimed at urban regeneration in a wider social, economic and physical sense - PROPERTY LED REGENERATION SCHEMES e.g Birmingham, London docklands
