CUE Flashcards
where are the main urbanised areas
North America (82%), Latin America, Caribbean and Europe
1950s suburban dream
- wanted own garden
- send children to good schools
- escape the crime in the cities
Albedo
Measure of how much light that hits a surface is reflected without being absorbed
Anthropogenic heat
Heat given off through human activity
associations of living in urban areas
- higher levels of literacy and education
- better health
- greater access to social services
- enhanced opportunities
benefits of counter urbanisation
- easier to find less skilled work in the countryside
- landowners can sell at a much higher price
- increase in demand and profit of rural services
- newcomers help to improve the environment eg conserve historical buildings and renovations
bid rent model
- the further from the CBD the cheaper the price of land
- the highest footfall is more expensive (CBD, retail areas)
Building materials
Specific heat capacity for concrete is one-third of soil
- vertical buildings surface area is increased in cities so absorbs more heat and releases it at night
Burges model
circle showing land use zoning in a city CDB, light manufacturing, low class residential, middle class residential, exclusive residential
causes of the heat island effect
- the presence of water
- arrangement and height of buildings
- pollutants
- building materials
- anthropogenic heat
consequences of urbanisation and urban growth
- urban sprawl
- shortage of houses is LICs and shortage of affordable housing in HICs
- lack of urban services and waste disposal
- unemployment and underemployment
- transport issues
core frame model
spatial variation in the CBD
- inner core - retail
- outer core - offices, cinemas etc
- frame - services - education, warehouses, transport, car sales etc
- zone of assimilation - an area of gentrified building
- zone of discard - land that is now derelict
Counter-urbanisation
The movement of people and employment from major settlements to smaller settlements
Decentralisation
New investment at the edge of the city
Deindustrialisation
The loss of jobs in the manufacturing sector
dry points
areas away from the risk of flooding
ecological footpront
the total area of productive land and water required to produce the resources a population consumes and absorb the waste product
edge cities
mixed offices, residential, and leisure spaces on the outer suburbs and near main roads
- land is cheaper
- people travel there for work or the services
- developed since 50s and 60s when car ownership increased
effects if suburbanisation
- urban sprawl
- congestion
- air pollution
evidence of counter urbanisation
- increase in commuter train stations
- increase house prices in these settlements
- increase in farm buildings being converted into housing
fortress landscapes/ development
anti-terrorist and crime prevention measure that produces a hostile urban environment
- increase security
- in suburban areas
- only those with permission can entre
- designed to give a safe environment
- divisive - only for rich
gap towns
towns between two areas of high land
gentrification and gentrified areas
the buying and renovation of houses and stores in deteriorated urban neighbourhoods by upper or middle income families or individuals - improving property values
- displaces poorest
- has a large range of services
government policy
the focus of regeneration will result from government ideologies at the time
Height/ arrangement of buildings
Tall buildings in close proximity - urban albedo is is lower than in rural areas
- vertical surfaces reflect heat and the radiated heat gets trapped as they are close together
how many people live in urban areas
over half the worlds population (2014)
- it was 30% in the 50’s
Hoyt model - 1939
based on the circles of the Burgess model but adds sectors of similar land uses concentrated in parts of the city
> zones radiate out from the CBD - follows lane of main roads and railways
human factors of an area
- trading centre
- government policy
- transport links
hyper-urbanisation
the urban increase in the urban population is happening so rapidly that the city cannot cope with the need of the people
impact of urban areas on wind
high pressure (rural) to low pressure (urban) > downdraught effect, speed effect, downwind eddy and counter-current effect, venturi effect
inequality
the economic differences between people at a variety of scale - relative
Infiltration trenches
- stone filled reservoir
- gradual infiltration
- enable storage, filtering and infiltration
- water and pollutants are moved into surrounding soil
liveability
the characteristics of a city, which improve the quality of life for the people living there
main changes to water balance in urban areas
- greater inputs from precipitation
- artificially imported water
- greater runoff
- runoff water has poor quality
- reduced evapotranspiration
- reduced infiltration
- less water is stored
- artificial drainage systems added
- more impermeable surfaces eg concrete
main groups that counter urbanise
- retired
- long distance commuters that can afford the cost
- people that work for rural firms
- people that work from home
main reasons for deindustrialisation
- mechanisation
- competition from abroad
- reduce in the demand
Mann model
combines Burges and Hoyt model > high class from south west has high class housing on the south west >heavy industry found along the main lines of communication
mature gentrification
high earning private sector professionals who buy properties already improved by others
Mega city
Population of over 10 million
Millionaire city
Population of 1 million to 10 million
municipal waste
everyday items discarded by the public collected by public bins
Permeable pavement
- run off through pours pavements
- filters and removes pollutants
- stored underground reservoir or goes straight into sub soil
- removes the need for drains and off site sewers
physical factors of an area
- wet points
- dry points
- gap towns
- resources
- relief
pioneer gentrification
purchase of rundown properties in deprived areas of the inner city
PLVI
Peak Land Value Interest
- land value gradually decreases the further from the city centre you get
- infrastructure intersection can increase footfall and therefore land value (causing peaks in value)
