Transformation of the motor vehicle fleet has been an important feature of the world’s peak car phenomenon. Very few urban transport studies have explored such important changes in large urban cities. Using an innovative green vehicle datasets constructed for 2009 and 2014, this paper investigates the ongoing change in urban private vehicle fleet efficiency (VFE) in Brisbane.
Across the world, the role and functionality of urban water utilities has evolved over time, in response to urban challenges. The role of the urban water sector in each region has generally begun with water supply, and then been followed by sewerage, drainage, environmental protection, and then water security efforts through the collection of alternative water sources, such as desalination and recycled water. Typically these services have been delivered through networks of underground pipes, and publicly inaccessible treatment facilities.
The separation of Australian housing production from its consumption has long-term consequences for sustainability in the built environment, and for anticipatory adaptation to climate change. This article investigates how the institutional structure of the Australian private housing development industry influences its risk profile and its ability to innovate, particularly in the type of housing produced. Consumers on the other hand are reluctant to invest in climate-adapted housing, particularly if adaptive products are costlier.
This short, exploratory paper reviews the concept of urban density from a historical and sociological perspective.
