Q

Fragmentation (PMWC)

A

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

41
Q

Globalisation (PMWC)

A

Shops, services and business are global brands and companies, rather than local. The has lead to the ‘clone town’.the Hugh street begins to die. A service sector economy that focuses on niche markets. Telecommunications dominate

42
Q

Simulation (PMWC)

A

Buildings often simulate heritage or other famous buildings/places. Cities planned in fragments, and focusing on aesthetic need rather than social needs. Buildings are often iconic and architecturally unusual often resulting in shock

43
Q

Beautification (PMWC)

A

Architecture is more an expression of art than a function in PMWC it is very varied with decorative ornamentation more common, often linked to the heritage of the city

44
Q

Fortification (PMWC)

A

-security is a key concern in PMWC’s, so fortress landscapes portend common: CCTV, bollards,street lights

45
Q

Information (PMWC)

A

PMWC’s are dominated by the service and knowledge economies - many people are employed in these sectors with global companies with commonly located in these cities

46
Q

Gentrification (PMWC)

A

This is a common process leading to change in the social landscape of cities, it also contributes to the increased polarisation (division into two sharply contrasting groups or sets of opinions or beliefs) between people in cities in term of wealth and access to service

47
Q

Decentralisation (PMWC)

A

Edge cities are commonly associated with PMWC’s especially as the term was first used in NA to describe cities like LA

48
Q

Privitisation (PMWC)

A

Cities are becoming more privately owned - thus could be public space, streets, squares or shopping centres

49
Q

Modern vs PMWC - how can they be compared

A
  • urban structure/form
  • landscape/architecture
  • economy
  • planning
  • culture&society
50
Q

How does urban structure/form differ in modern cities than in PMWC’s

A

In modern cities they are planned in totality rather than in smaller sections whereas in PMWC’s cities are planned in fragments + focusing on aesthetic needs rather than social needs

51
Q

How does landscape/architecture differ in modern cities than in PMWC’s

A

In modern cities a landscape is dominated by very functional architecture whereas in PMWC’s architecture is more of an expression of art than a function

52
Q

How does economy differ in modern cities than in PMWC’s

A

In modern cities it was focussed on mass production (EOS, service secor gaining in importance) whereas in a PMWC’s it is a service secor based economy focusing on niche markets (telecommunications dominate)

53
Q

How does planning differ in modern cities than in PMWC’s

A

In modern cities CBD + steady decline in land values away from centre whereas in PMWC’s there is a multi-nodal structure containing high-tech corridors and post suburban developments (edge cities may be evident

54
Q

How does culture&society differ in modern cities than in PMWC’s

A

In modern cities there are divisions of lass found within the city (a large homogeneity across city) whereas in PMWC’s there is ethnic diversity, resulting in a city that is heavily fragmented culturally with a Hugh degree of social polarisation in some areas (groups distinguished by their consumption patterns)

55
Q

Cultural diversity

A

Existence of a variety of cultural/ethnic group within a society

56
Q

Diaspora

A

A group of people with similar heritage or homeland who have settled elsewhere I’m the world

59
Q

60
Q

Poverty

A

An absolute term referring to a poor standard of living which doesn’t change over time

61
Q

Inequality

A

Refers to the economic differences between people at a variety of scale. This is all relative and not like poverty

62
Q

7 Dimensions of deprivation

A
  1. Income
  2. Employment
  3. Health and disability
  4. Education, skills and training
  5. Crime
  6. Housing and services
  7. Living environment
63
Q

Venturi effect

A

Wind funnelled into narrow urban canyons crated by tall buildings, speeds up as it becomes more restricted

64
Q

Urban heat island (UHI)

A

Is an urban area or metropolitan area that is significantly warmer than its surrounding rural area due to human activities

65
Q

Albedo

A

Is measure of how much light that hits a surface is reflected without being absorbed

66
Q

Sky-view factor

A

The amount of sky we can see without our view being impeded by tall buildings

67
Q

Specific heat capacity

A

A measure of the energy required to raise the temperature of 1kg of material by 1 degrees Celsius

68
Q

What causes the urban heat island effect

A
  • anthropogenic heat
  • height/arrangement of buildings
  • the presence of water
  • pollutants
  • building materials
69
Q

Anthropogenic heat

A

human activity - vehicles, heating, industry

70
Q

Height/arrangement of buildings

A

urban albedo is much higher than rural - absorb more heat, verticals buildings reflect heat + close together = lower sky-view factor, radiated heat gets trapped

71
Q

The presence of water

A
  • Radiated heat can be transferred as sensible heat (heat that can be felt) or latent heat (evaporates water). After evapotranspiration any left over heat is used to warm the air
  • the more sensible heat that enters the atmosphere, the warmer it gets. As there is little water in urban areas latent heat is needed less so becomes sensible heat further warming the air
72
Q

Pollutants

A
  • These have both a cooling and heating effect
  • dust and smog can reduce sunlight by as much as 6% causing a cooling effect
  • CO2 absorbs long-wave radiation which heats the urban dome further
73
Q

Building materials

A

Compared to rural areas, urban areas heat up more quickly. The specific heat capacity for concrete is one third that of bare soil, and so for a given input of energy, concrete will warm up more quickly. With vertical buildings, surface area is increased in cities and so absorbs more heat. This gets released at night

74
Q

How much more precipitation than rural areas

A

5-15%

75
Q

Sustainable urban drainage systems (SUDS)

A

A sustainable way to prevent flooding by reducing surface run off using a variety of techniques

76
Q

Types of SUDS

A
  • Swales
  • wetland
  • permeable pavement
  • infiltration trenches
77
Q

Swales

A
  • A sunken/marshy place incorporated into ornamental amenity and screen planned areas where they would be looked after as part of normal maintenance control
  • they provide temporary storage for storm water, reduce peak flows to facilitate a bit of extra area for infiltration. Installed alongside roads to replace kerbs (saving costs)
78
Q

Wetland

A
  • contribute to visual amenity and biodiversity. Can accommodate considerable variations in water levels during storms (enhancing flood storage capacity)
  • the algae and plants of wetlands provide a partially good level of filtering and nutrient removal
79
Q

Permeable pavements

A

Changing surface to make them more pores so more water can infiltrate.

80
Q

Infiltration trenches

A

Store filled reservoirs to which storm water runoff is directed, then infiltrates into the ground. Longevity enhanced by incorporating a filter grip[, guly or sump pit to remove excess solids at the inflow

81
Q

What is the hierarchy from waste from best to worst

A
  • reduce (diversion)
  • reuse (diversion)
  • recycle (diversion)
  • recovery (diversion)
  • landfill (disposal)
  • incineration (disposal)
  • controlled dump (disposal)
82
Q

Reduce (waste diversion)

A

Reduce the quantity of waste by reducing packaging and reducing consumption

83
Q

Reuse (waste diversion)

A

Reuse products/containers. For example a number of outlets now encourage you to bring your old containers to fill up items such as washing liquid and detergent

84
Q

Recycle (waste diversion)

A

Recycling is carried out when materials from the item can be reprocessed into new products. In recent years global demand for recyclables has grown enormously

85
Q

Recovery (waste diversion)

A

Recovery is the process of recovering compounds and elements from products, buildings, and waste materials, composting or energy production

86
Q

Landfill (waste disposal)

A

The placing of waste in man-made pits or excavations

87
Q

Incineration (waste disposal)
