Australia’s cities face significant social, economic and environmental challenges, driven by population growth and rapid urbanisation. The pressure to increase the availability of housing, including a move to a more compact urban form, will lead to greater levels of high-density and medium-density stock.
Cities are comprised of hundreds of thousands, if not millions, of small parcels of individually owned land. The fractured nature of these tenures, combined with the network of administrative and infrastructural bodies governing them, makes any form of significant and coordinated planning change incredibly complicated, if not untenable.
This paper explores the redevelopment potential of ageing and underutilised public housing properties in the middle suburbs of major Australian cities. State governments lack strategies for the renewal of this housing in the current fiscally constrained environment.
Due to the unsustainable nature of urban sprawl, Australian metropolitan strategies have increasing been pushing for increased levels of infill: the redevelopment of existing urban (typically residential) land. However, the current infill models of Brownfield and lot-by-lot redevelopment are largely incapable of generating the volume or range of future housing needs.
This short, exploratory paper reviews the concept of urban density from a historical and sociological perspective. It argues the emphasis dedicated to urban density in Australian planning schemes risks diverting energies away from potentially more fruitful avenues for the achievement of sustainability.
Trees are known for their positive impacts in cities including: the provision of shade, reducing heat island effects, improving amenity, reducing social vulnerability, processing carbon and improving health outcomes. Perhaps unsurprisingly, greening policies at the local and state level have proliferated. Despite these initiatives, tree cover remains stubbornly uneven.
Abstract: Visions and Pathways 2040 is a research and engagement project that seeks to envision possible future forms of Australian cities and lifestyles in 2040 if they have achieved an 80% reduction in their greenhouse gas emissions (on 2013 levels) and have addressed broader resilience issues, and, secondly, to ‘backcast’ from visions possible pathways to the present that may, in turn, sugge
This paper proposes a methodology and a conceptual framework for evaluating green infrastructure performance. This proposed framework combines three key themes: ecosystem services, human health and wellbeing and ecosystem health.
