Q

what are the causes of urbanisation in HICs?

A

industrialisation led to the creation of the factories

the factory system contributed to the growth of urban areas as large numbers of workers migrated into the cities in search of work in the factories (pull factors)

E.g. in England + Wales, the proportion of the population living in cities jumped from 17% (in 1801) to 72% (in 1891)

Q

In what ways are the causes of urbanisation in today’s LICs/NEEs similar/different to these causes?

A

similarities:
- both caused by rural to urban migration (push + pull factors play a big role)
- both caused by natural increase

differences:
- driven in HICs by natural economic progression (Industrial Revolution) whereas often dictated by presence of TNCs in NEEs/LICs
- HICs status means they are able to industrialise quicker

Q

what negative impacts does urban sprawl have?

A

more roads/infrastructure needed- economic + environmental - loss of green space/extra air pollution

habitat loss- environmental - displaces local species + reduces biodiversity

increased commuting- social - increases stress for people before they even start work
environmental- more cars on the road = more CO2 in atmosphere

increased air pollution- social - can lead to health issues
environmental - contributes to climate change

loss of farmland/open space - economic - can lead to loss in agricultural industry
social - can have health/mental health impacts on people

reduced urban drainage- environmental- increases surface run off as drains are blocked which can lead to flooding and water quality issues – becomes increasingly important due to pollutants from urban areas being washed into rivers or ground water

decentralisation- trying to improve economies in specific areas + creating jobs

homogenisation of the landscapes- increases similarities between towns + cities regardless of their geographical location

Q

what are the management strategies to reduce economic inequality in Rio?

A

using education to reduce unemployment

17
Q

what environmental problems has urbanisation led to in Rio and the management strategies used?

A

atmospheric pollution- 40% of cars increase in last decade
- management: coast roads are one way during rush hour; expansion of the metro system (train + subway); toll roads to reduce traffic congestion

water pollution- due to problematic pipes
- management: ships are fined for disposing of their fuel into the bay; 12 new sewage works have been built since 2004; 5km of sewage pipes built around favelas

dereliction- can sometimes cause contaminated land
- management: treatment of land; use brownfield sites to create olympic venues (reused for community sporting activities)

18
Q

what has caused a rapid rise of megacities?

A

globalisation
economic competition
perception of a better life in cities
mass migration

19
Q

what problems occur with megacities forming in LICs/NEEs?

A

growth in population is not matched by a growth in resources + infrastructure

challenge of providing employment, housing and basic services

concerns about how city authorities can effectively govern such large cities

20
Q

what are the benefits of megacities?

A

globally:
- on average, they produce 2-3x more GDP than other cities

  • centres of innovation - many solutions to global problems are trialled
  • less damaging to the environment to provide transport, electricity, housing, water + sanitation for a dense urban population than a dispersed rural one

regionally:
- on average, they produce 2-3x more GPD than other cities

  • offer opportunities to expand access to services such as health care and education for large numbers
  • less damaging to the environment to provide transport, electricity, housing, water + sanitation for a dense urban population than a dispersed rural one
  • urban dwellers have access to larger + more diversified employment markets
  • better levels of employment and healthcare - can improve quality of life and empower women
  • growth of large urban areas can fuel public pressure for change
21
Q

what is the link between megacities + economic development?

A
  • megacities dominate national + regional economies of countries
  • many companies have their HQ in megacities
  • encourages population growth which leads to the desirability of goods + services
  • all megacities act as service centres within the formal economic sectors
  • megacities in the developing world are also important manufacturing centres (e.g. Mumbai in India/ Dhaka in Bangladesh) with thousands working in the informal sector
22
Q

Urban change in HICs (Britain)…
(past)

A
  • 1851 census recorded 1/2 of Britain’s population as living in urban areas (first society in history to do so)
  • Inner cities at the time were poverty stricken, life expectancy was low (30), poor sanitation, high levels of pollution (land, air and water) due to lack of legislation
  • chances of employment and higher wages were greater in urban areas
  • community spirit was strong + crime was low
  • since Victorian times, contrasts between the rich + poor have progressively increased + diverse spatial inequalities have occurred as a result
23
Q

recent characteristic features of Britain’s inner cities…

A
  • high levels of out migration
  • empty + derelict properties
  • low levels of educational attainment/aspirations
  • high levels of unemployment
  • high rates of crime, vandalism + graffiti
  • low levels of participation in local democracy
  • economic decline, personal poverty, social problems + environmental decay
24
Q

what is decentralisation?

A

movement of population + industry form the urban centre to outlying areas

25
Q

process of suburbanisation in HICs…

A

began in 1830s - few planning controls + urban growth took place along main roads (ribbon developments)

presence of arterial routed enabled wealthier people to move out + live some distance from their place of work

by the 1940s - this growth + growth between the ‘ribbons’ was a concern and led to the creation of green belts

during 1950/60s - large scale construction of council housing took place on the only land available - suburban fringes

1970s - move towards home ownership - led to private housing estates bring built on urban fringe - allowed people to have more land for gardens + more public open space

as car ownership grew, edges of towns had space for car parking + became the favourite location for new offices, shopping centres + factories that were being built

26
Q

Didsbury….

A

prior to Industrial Revolution, it was a small agricultural hamlet

with growth of railways, Didsbury was absorbed by the resultant urban sprawl, became part of city of Manchester in 1904

nowadays, one of most desirable places to live

population approx 27,000

a number of business are located in Didsbury on the Towers Business Park (e.g. British Airways (consumer sales department))

27
Q

what are the social effects of suburbanisation? (Didsbury)

A
  • the influx of newcomers results in landuse change
    -> new housing estates are
    constructed
    -> new services appear such as retail (e.g. Tescos, M&s simply food) and entertainment facilities (Parrs Wood entertainment complex)
  • social segregation becomes an issue
  • good schools (however can reinforce social segregation as affluent move into areas to get their kids into good schools)
  • 10% most deprived in UK - 1/2 of children living in central Manchester are in poverty
28
Q

what are the economic effects of suburbanisation? (Didsbury)

A
  • highly sought after expensive housing - Didsbury over £750K for a detached family home
  • shops and other businesses relocate to the suburbs - town centres may go into a decline as a result
  • town centres respond with redevelopment schemes to revitalise the CBD
  • can lead to high unemployment and deprivation
  • Towers Business Park: businesses relocate to suburbs in search of easy access to M60 and Manchester airport
  • cheaper land (+ nicer environment)
29
Q

what are the environmental effects of suburbanisation? (Didsbury)

A
  • extension of the urban area = more impermeable tarmac and concrete surfaces - increases flood risk (in the Mersey Valley area, Didsbury)
  • new residents and commercial developments intrude on open space/ countryside (e.g. designated green belt land to the south of Didsbury, bordering the river Mersey.)
  • wildlife habitats and small scale ecosystems may be negatively effected
  • brownfield sites become available for redevelopment (e.g. Castlefield)
  • congestion and air pollution
30
Q

What are edge cities?

A

self contained settlements which have emerged beyond the original city boundary + developed as cities in their own right

form largely as a result of urban sprawl

31
Q

where do they form?

A

develop close to major roads/airports + tend to be found in close proximity to shops, offices + other businesses which decentralised from the original city

may lack a clear structure but they do have a wide range of amenities (incl. shopping malls, schools + entertainment facilities)

32
Q

what are the advantages of edge cities?

A
  • nicer surroundings
  • houses tend to be more affordable and bigger
  • not often tightly packed like inner cities
  • new jobs by attracting workers from the metropolitan areas around it leading to urban development + business expansion
33
Q

what are the disadvantages of edge cities?

A
  • social segregation
    -> this is where the wealthy have moved to the new suburban settlements leaving the poor + disadvantaged sections of society in the original city boundaries
  • people move to these areas + can still work in cities thus more cars on the road - more CO2
34
Q

why are edge cities an effect of suburbanisation?

A

suburbanisation = the physical spreading of a city into surrounding countryside areas (urban sprawls) = edge cities

as people move out of inner city areas into suburban areas = more demand for services rising in these areas = edge cities become functioning area of its own

35
Q

what is deindustrialisation?

A

refers to loss of jobs in the manufacturing sector - occurred in UK end of 20th C

36
Q

why did deindustrialisation occur in UK?

A
  • fall in employment in traditional manufacturing industries (coal, steam power, railways etc)
  • between 1961 + 1981 >1.6m manufacturing jobs were lost in major urban areas - 75% jobs lost nationally
37
Q

what are the causes of deindustrialisation?

A
  • mechanisation: cheaper to use machines for produce rather than people
  • competition from abroad: rapidly industrialising economies (India, China, Taiwan, S. Korea etc)
  • reduced demand for trad products as new materials and tech developed
