Q

Advantages of megacities

A
  • POLITICAL: more liberal and carry global political power due to size of populations
  • ECONOMY: UN estimates megacities generate 2-3 x more GDP than other cities
  • ENVIRONMENT: better for environment in terms of transport, electricity water and sanitation as population is all in 1 place
  • SOCIAL: better access to services like HC and ED
  • EMPLOYMENT: population have more access to diversified employment markets. informal economy provides work for poorest or those without official status.
  • TECHNOLOGICAL: megacities are often centres of innovation where solutions for global problems are trailled.

Q

Disadvantages of megacities

A
  • TRANSPORT: can be bad if not managed leading to congestion and pollution
  • POVERTY: as its hard to provide jobs, housing and infrastructure
  • ENVIRONMENT: as more dumps to deal with waste EG. Mumbai produces 6,500 tonnes a day in a creek near a residential. climate change is also affected and expansion removed biodiversity EG urban land will have expanded 3.3 million km2 by 2030
  • People pushed to MARGINAL LAND facing flooding and disease
  • Slum dwellers face an increased CRIME levels because of poor migrants
  • CONFLICT and riots due to bad governance EG Data
  • Not enough resources or services

Q

How has the growth of megacities changed?

A

In 1960 the only 2 megacities were NY and Tokyo
It took 150 years for London to grow to 7 million, but only took 50 years for Mexico City to grow to 15 million, so they are growing more rapidly
Asia has the most megacities, due to its high population. there are 9 megacities in china.
Mostly in LIC/NEE now

Q

History of suburbanisation

A

First happened in USA during WW1 where many African Americans moved north to south looking for jobs
As a result many white families moved out of the cities-white flight
This was also seen in the UK in 1950-60’s as there was a shortage of workforce after the world war so government encouraged people from British empire to move to the UK, where they searched for jobs in city and white flight occurred
2019 onwards far more people work from home and some jobs have moved to the suburbs (decentralisation)

Q

factors leading to increased demand in housing

A

natural increase (better HC)
migration
increased divorces so less people per house

22
Q

Deindustrialisation

A

decline in importance of industrial activity for a place , specifically may refer to a falling % or population who work in manufacturing/declining contribution of manufacturing to GDP

23
Q

Causes of deindustrialisation

A
  • global shift occurred due to lower land prices and low labour costs EG.china
  • technological changes have made some industries obsolete
24
Q

Cities where deindustrialisation occurred

A

Liverpool- was a port but ended in 1970’s when changes in global trade made Bristol down south more popular. 2,000 businesses closed like textiles and engineering and 200,000 jobs were lost
Manchester- 50,000 jobs were lost in textiles and heavy engineering and chemicals with 1/5 of population lost
Cardiff- decline of coal and steel industries made the port suffer from being the 2nd largest in the world

25
Negative effects of deindustrialisation
positive feedback cycle of deprivation: people move out as loose jobs -> empty houses boarded up -> poorer residents move in -> less community cohesion, environment deteriorates -> vandalism, crime drugs -> reputation or area declines so lack of investment -> poor services as less income for council -> people leave ect.
26
Positive feedback cycle of deprivation from deindustrialisation
people move out as loose jobs -> empty houses boarded up -> poorer residents move in -> less community cohesion, environment deteriorates -> vandalism, crime drugs -> reputation or area declines so lack of investment -> poor services as less income for council -> people leave ect.
27
Benefits of deindustrialisation for UK
Social- fewer people working in dangerous or unhealthy conditions. improved working opportunities for women in tertiary work Economic- more people earning high salaries tertiary industries Environmental- fewer polluting industries and lower carbon emissions
28
Costs of deindustrialisation for UK
Social- loss of sense of place for communities built around factories and mines social problems from cycle of deprivation- crime rates increase, less shops and services Economic- loss of industry long term unemployment of older factory workers or miners Environmental- carbon emissions have been offshore not reduced as imports and mechanisation brownfield sites, dereliction, pollution from chemicals
29
Premature deindustrialisation
the fall in the relative importance of manufacturing that occurs sooner than expected in emerging economies based on previous countries
30
Premature deindustrialisation
the fall in the relative importance of manufacturing that occurs sooner than expected in emerging economies based on previous countries (after just decades of first factories)
31
Impacts of premature deindustrialisation
shorter gap between industrial take off and peak industrialisation after just decades means income due to industrialisation has been lower fewer jobs created -doesn't make use of demographic dividend. not good as violence in Middle East stems from youth unemployment if populations can be well educated then they can skip the factory employment and work in the tertiary sector
32
cause of premature deindustrialisation
mechanisation- AI and robotics | EG. sewbots in Bangladesh for sewing
33
What are the changes in industries and why?
PRIMARY- Decreased in industrial period as mechanisation occurred. work went to china as strength of pound increased. SECONDARY- increased in pre-industrial as rebuilt after war. peaked in industrial period because the invention of machinery started factories and people built ships and worked in steel making and textiles. People demanded these products. decreased in post industrial because foreign industries became competitive and imports more affordable in NEE's. manufacturing was 25% of jobs in 1970's Uk but now only 8%. TERTIARY- increased in industrial and peaked in post industrial because people needed to sell the manufactured products. demand for work increased in schools, hospitals and retail. Rural urban migration for better jobs. greater demand as QOL increases, and more women working. QUATERNARY- relatively new concept as technology has only been developed recently.
34
Why was urban resurgence needed? | what will it do?
Environmental: pollution from old factories, vandalism, lack fo green space Economic: unemployment, poverty, low income, lack of space for new industries and poor access Social problems: crime, falling birth rates, high concentration of ethnic groups and concentrations of very young and old Attract young professionals who desire to be near work, close to leisure and entertainment with a lively atmosphere of cities without city problems
35
Regeneration policies:
URBAN DEVELOPMENT CORPORATIONS: property lead initiatives set up in 1980's where local businesses were encouraged to invest in derelict land and then less to private businesses. A- attracts new businesses and improves environment . by 1990's £12 billion private sector investment and 190,000 jobs D-locals didn't get much say, new housing and jobs didn't benefit them EG. London Docklands CITY CHALLENGE: 1990's competition led policy where best scheme won government grant. local leadership. A- better schemes were created. created 53,000 jobs and reclaimed 2,000 Ha of derelict land D- previously funded areas lost funding, money lost repairing bids, resources spread thinly EG. Manchester Derm valley partnership NEW DEAL FOR COMMUNITIES: 2000's involved 10yr programmes to transform the 39 most deprived neighbourhoods and improve QOL. A- improvement in 32/36 core indicators. urban design was dressed with an architect. managed by locals so specific needs met. D- bigger impact on places than people. little change in unemployment and education- main aims EG. New islington millennium village Future- devolution of power EG greater Manchester 2014
36
What is gentrification?
richer people buy property and do it up, improving environment and taxes, but pushing poorer locals out by increasing rent and property values. bigger chain stores move in due to increased rent. EG. Nine elms in Battersea- 20,000 new homes are developed on brownfield site. state led gentrification encouraged by local government. however most housing is sold to out of area, even If a fraction must be affordable, as developers want money.
37
Types of industries:
Primary- produce raw materials for industry EG mining Secondary- manufacturing and assembly industries taking raw materials into finished products EG steel manufacturing Tertiary- service industries EG teachers Quaternary- research and development industries EG development of new computer components
38
why has the service industry increased?
increased foreign investment increased demand at home slow growth of manufacturing and construction 77% of Uk economy in 2015
39
How is decentralisation achieved? | what is an example?
by the devolution of power | greater Manchester in 2014 selected its own mayor
40
What is the purpose of greenbelts?
1. prevent urban sprawl 2. prevent neighboring towns and cities merging 3. preserve character of historic towns and cities 4. protect green open space 5. provide recreational areas close to population areas 6. to protect agricultural land 7. to assist in urban regeneration by forcing developers to build on brownfield sites
41
Advantages of greenbelts
stop urban sprawl | stop unwanted development on rural urban fringe
42
Disadvantages of greenbelts
developers forced onto more rural land beyond greenbelt encouraging counter urbanisation which causes more commuting, more roads, increased car use, traffic, congestion and pollution densely packed housing estates land prices increase and so do house prices
43
Issues of suburbanisation and management strategies::
ECONOMIC: businesses choosing to locate in inner city (urban resurgence) when young are- marrying and children later, less likely to drive EG. google moved to kings cross industries like IT don't need central base as work from home economy of suburbs under pressure MANAGEMENT:green economy and medicine may be future industries HOUSING: more deprived areas that are older and more children, and more ethnically diverse complex needs and needs more resources MANAGEMENT: London mayor has plans to change housing policies to more affordable and more facilities to support growth TRANSPORT: inadequate public transport for off peak trips heavy traffic on key routes 2/3 of all journeys in outer London are made by car MANAGEMENT: investment into bus network crossrail reclassification of travel zones to make journeys cheaper EG Waterloo new bike storage and pedestrian access improved ENVIRONMENTAL: higher carbon emissions in suburbs due to car use energy inefficient homes MANAGEMENT: bike storage units to reduce pollution retrofitting schemes to improve energy efficiency and new builds are efficient
44
Facts about suburbs
home to 60% of city's population | provide 1.9 million jobs generating 1/3 of Londons GDP
45
Consequence of suburbanisation on the inner city:
``` A- lower density housing can be made better environment as derelict land is removed and recreational land created D- loss of jobs in city and poverty derelict buildings deter investment decline of CBD ```
46
Consequence of suburbanisation in suburbs:
A- increased employment in offices and shops recreational facilities D- villages loose character, school places for locals increase house prices mean hard for young ppl to stay increased congestion and pollution from commuters greater polarisation between suburbs and inner city in terms of ethnicity, affluence, education, employment pressure on greenbelt
47
burgess model
``` CBD Inner city inner suburbs outer suburbs R-U Fringe Greenbelt 1930's along roads 1940's further back from roads 1950's council estates 1970's private estates ```
48
Facts about green belts
first put into law in 1947 14 today around most major UK cities cover 15% of Uk land area owned by local authorities with strict restrictions on development
49
Can megacities be sustainable?
if regulations for environment keep green spaces and low carbon emissions services and housing need to grow quick to reduce poverty
50
General economic, social, technological, political and demographic processes associated with urbanisation:
Employment opportunities access to HC, education, transport services towns loose customers due to internet or large shopping centres new advances in technology allow buildings to be even taller politically urban areas are becoming more influential in national and international affairs natural increase and migration is a key component, with rural urban migration very fast in developing countries economic growth is helped by flow of migrant workers keeping wages low and maximising profits more bars, restaurants and pedestrianised areas and public transport also increase economic prosperity
