Impacts of the urban sprawl challenge

Question 1

what does urban sprawl affect

Answer 1

Urban sprawl affects the environment, economy, and society, with consequences for biodiversity, infrastructure costs, transportation, and community well-being.

Question 2

Environmental impacts:

Answer 2

Greenfield developments in outer areas lead to land clearing and habitat fragmentation.

Only 29% of original vegetation remains in the metropolitan area.

Threatens unique flora and fauna, like Carnaby’s black cockatoo.

Habitat destruction and fragmentation negatively affect native species.

Question 3

Economic impacts:

Answer 3

Government faces higher costs for infrastructure services in outer areas.

Greenfield sites cost three times more to the government than infill sites.

Concentration of jobs in the city center results in longer commutes for outer suburb residents.

High car dependency leads to congestion, air quality issues, and economic costs

Question 4

Social impacts:

Answer 4

Sprawling suburbs lack urban amenity and greenery.

Canopy cover in the metropolitan area is only 20%, compared to 30% average in other Australian capitals.

Higher tree coverage leads to increased property values, mental wellness, and reduced stress.

Socio-spatial inequality arises due to delayed availability of services in new developments.

Example of Ellenbrook suburb waiting for essential infrastructure like a trainline.
