Key Knowldge Flashcards
Urban growth
The increase in the total population of a town or city
Urban expansion
The increase in size or geographical footprint of a city
Urbanisation
The increase in the proportion of people who live in urban settlements
Suburbanisation
Outward spread of built up area, often at lower densities. People moving from urban centre to the edge of the urban area
Urban sprawl
Continued outward spread consuming smaller towns/villages
Counter urbanisation
The movement off people and employment from major settlements to smaller settlements
reurbanisation
The movement of people and employment back into city centres
What is the Brandt line
Division of the world on rich north and poor south, (USA, Europe, Asia and Australia)
Mega city
A mega city is a metropolitan area (urban) with a total population in excess of 10 million people
Million city
A city of more than a million people
World city
Cities that are seen to have an important role in the global economic system (London, Tokyo, NYC, Paris)
As of 2008 what % of people live in urban areas
More than 50%
What are the top 3 biggest cities
- Tokyo - 37.5m
- Delhi - 29.4m
- Shanghai - 26.3m
How has the location of the worlds biggest cities changed since 1945
1945 = London & Paris -> now = south-east asia
How has the size of the worlds biggest cities changed since 1945
1945 = around 5m people -> today biggest mega city is over 30 m
The global pattern of the % of people living in urban areas
- most of the worlds population still has less than 80% living in urban areas
- anomalies -> large cities found on the west coast of Africa
- many cities with 5m+ people living there are found in south-east asia
How are the rates of urbanisation changing in each continent
- Europe: slowest 9already urbanised)
- Asia: faster rate but slowing Dow in some regions
- Africa: fastest rates of urbanisation
Causes of urban growth
- natural population growth
- rural-urban migration (better opportunities, better healthcare, agricultural problems, quality of life, education)
Deindustrialisation
Refers to the loss of jobs in the manufacturing sector
Impacts of deindustrialisation
- economic: increased demand for benefits, loss of tax leading to a decline in services, de-multiplier affect in urban areas
- social: loss of confidence ad morale, increased levels of crime + family breakdown and substance abuse
- environmental: increase in noise, land and water pollution and traffic congestion, decline in maintenance of local housing caused by lower incomes, long-term pollution from dirty industries
The burgess model structure
- CBD (shops, offices, entertainment, few houses, expensive land)
- Inner city (small terraced houses - high density, land still expensive, some old disused factories)
- inner suburbs (semi-detached housing, open space/parks, shopping centres, medium density housing, near main roads, council estates
- outer suburbs - rural-urban fringe (large detached houses, plenty of open space, some council estates, culdesacs, low density housing, commuters)
Decentralisation
Movement of people and businesses out of city centre to edge
Causes of decentralisation
- cheaper to build on greenfield site
- better infrastructure
- links to universities
Mixed development and an example
- blends residential, commercial, cultural, institutional and industrial uses which re interconnected physically and also functually
- example: Cardiff bay
Pros of mixed development
- more socially diverse
- attracts people back to the city
- developed night life
- should help prevent/address CBD decline
cons of mixed development
- necessary high level of security
- potential social segregation
Cultural and heritage quarters and examples
- heritage quarters focus on the history of the area based around small scale industries -> Birmingham jewellery quarter
- cultural production (making objects, goods, products) or consumption (galleries, sows etc) -> Sheffield cultural industries quater
Pros of cultural and heritage quarters
- increased busses
- links to cultural past
Cons of cultural and heritage quarters
- mixed development want to remove them
Gentrified areas and an example
The buying and renovation of holders and stores in deteriorated urban neighbourhoods by upper or middle income families or individuals, thus improving property but often displacing low income families and small businesses in the area -> Notting Hill, Islington
Pros of gentrified areas
- increase housing value
- attracts young professionals to area, therefore bringing wealth
- improved social + building fabric
Cons of gentrified areas
- displacement of poor
- social tensions (divides)
- culture of area can be lost
- loss of people in state schools
Fortress landscapes with an example
- refers to landscapes designed around security, protection, surveillance and exclusion -> US embassy in London
- greater use of CCTV
- railing/fencing around private spaces
Pros of fortress landscapes
- feeling of safety
- detergent - reduces chances of incidents occurring
- creates security jobs
Cons of fortress landscapes
- intimidation
- can be exclusive
- expensive
Edge cities and an example
Characterised by mixed office, residential and leisure spaces and tend to be located in the outer suburbs near to motorway or main road junctions (self contained0 9happens because of urban sprawl) -> LA
Pros of edge cities
- greenfield site is cheaper
Cons of edge cities
- huge amounts of segregation
What are the characteristics of PMWC’s
- Fragmentation
- Globalisation
- Simulation
- Beautification
- Fortification
- Information
- Gentrification
- Decentralise
- Privatisation
Fragmentation (PMWC)
Cities are more ethnically diverse, but social and cultural inequalities and segregation are made common the division between ‘rich’ and ‘poor’ is often stark and planned resulting in areas of extreme wealth alongside areas of extreme poverty
