Urban Growth and Decline
Issues in the Australian Environment: Urban Processes
Cities are always changing
Urban consolidation
Urban decline
Gentrification
Urban renewal
Change involves four urban processes
Sydney has changed since 1788
Sydney has grown out from a centre
The area of first settlement has changed

Cities can be represented by circlesThe 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
There’s Consolidation of people in some places
In other places change in social and economic status occurs - Gentrification
As cities growth they spread outwards
Geographers often use models like this
Models help us understand the real world
Models aren’t entirely accurate
Models have aspects that are accurate
We can apply this circular model to Sydney
Do you think it applies to Sydney?
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
Sydney CBD
Zone of management administration &
major retailing, where urban transport
converges ensuring accessiblity
Around the CBD a factory zone develops
Car factory Zetland
Industry develops close to CBD
administration, markets, labour, port
sites and rail yards
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.
Next a zone of newer housing
Housing Haberfield
Residential zone working class and upwardly mobile people, close to
employment in inner zones
Then a zone of even newer houses
Macquarie Links
Higher quality new housing on larger blocks, residents commute & have
higher transport costs
Beyond is the rural urban fringe
Mulgoa
Mixed rural and high class residential area. Residents commute
by train, often drive to railway stations
Does this describe the way Sydney is ?

Much has changed
Mulgoa
There are no longer factories in Zetland
Rozelle has undergone ‘gentrification’
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.
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.
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.
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..
