Urban Growth and Decline Issues in the Australian Environment:
Urban Processes
Slide 2
Cities are always changing Urban consolidation Urban decline
Gentrification Urban renewal Change involves four urban
processes
Slide 3
Sydney has changed since 1788 Sydney has grown out from a
centre
Slide 4
The area of first settlement has changed City from Pyrmont
1880s
Slide 5
The same view from in Pyrmont 2010 Can you see anything from
the 1880s?
Slide 6
The view from Pyrmont Bridge 2010 Can you see anything from the
1880s?
Slide 7
The area of first settlement has changed A view of Darling
Harbour, 1880s
Slide 8
View across Darling Harbour 2010 Can you see anything from the
1880s?
Slide 9
The area of first settlement has changed 1902
Slide 10
The area of first settlement has changed Can you see anything
from 1902?
Slide 11
Cities can be represented by circles The area of first
settlement Outward growth Cities grow out from areas of first
settlement, and as they grow certain processes occur: Some areas
Decline In some areas there is Renewal Theres Consolidation of
people in some places In other places change in social and economic
status occurs - Gentrification
Slide 12
As cities growth they spread outwards
Slide 13
Geographers often use models like this Models help us
understand the real world Models arent entirely accurate Models
have aspects that are accurate We can apply this circular model to
Sydney Do you think it applies to Sydney?
Slide 14
As cities growth they spread outwards The area of first
settlement develops as the Central Business District. Here the most
intense business activity takes place Sydney CBD Zone of management
administration & major retailing, where urban transport
converges ensuring accessiblity
Slide 15
Around the CBD a factory zone develops Car factory Zetland
Industry develops close to CBD administration, markets, labour,
port sites and rail yards
Slide 16
Then a zone of housing and factories Rozelle & White Bay
Industry expands into the area. The poorest people and housing
conditions, high levels of pollution and congestion.
Slide 17
Next a zone of newer housing Housing Haberfield Residential
zone working class and upwardly mobile people, close to employment
in inner zones
Slide 18
Then a zone of even newer houses Macquarie Links Higher quality
new housing on larger blocks, residents commute & have higher
transport costs
Slide 19
Beyond is the rural urban fringe Mulgoa Mixed rural and high
class residential area. Residents commute by train, often drive to
railway stations
Slide 20
Does this describe the way Sydney is ? Sydney CBD Car factory
Zetland Rozelle & White Bay Housing Haberfield Macquarie Links
Much has changed Mulgoa There are no longer factories in Zetland
Rozelle has undergone gentrification
Slide 21
Suburbs like Zetland have become areas of urban consolidation
with dense settlement & high rise apartment development Urban
consolidation involves increasing the amount of medium to high
density housing in areas that already have urban infrastructure in
place, such as old industrial areas.
Slide 22
Suburbs like Annandale, Camperdown, Rozelle, Balmain, Lilyfield
& Leichhardt have become expensive places to live. They have
been the sites of Gentrification. Gentrification involves new
groups of wealthy people moving into poor neighbourhoods and
renovating the houses or sometimes building new ones.
Slide 23
Suburbs like Annandale, Camperdown, Rozelle, Balmain, Lilyfield
& Leichhardt have also experienced Urban Decline With Urban
Decline buildings and infrastructure fall into disrepair and
dilapadation. It is sometimes called Urban decay. Businesses close
and sometimes buildings become derelict and the intensity of land
use declines.
Slide 24
Suburbs like Annandale, Camperdown, Rozelle, Balmain, Lilyfield
& Leichhardt have also experienced Urban Renewal In the older
parts of Sydney Urban renewal is apparent as changing economic
conditions, new technology and the increasing expense of locating
people and services on the urban fringe, make inner city living and
working most attractive.. The Old Piano Factory, Annandale
