Options Analysis: Costs and Benefits of Urban Tree Canopy Options for Minor Infill Development in the Planning and Design Code, A Report to the Attorney-General’s Department

To determine the most cost-effective way to balance urban tree canopy and infill outcomes, this study tested two policy options for the new Planning and Design Code: # Option 1: Draft Planning and Design Code policy for one onsite tree per allotment # Option 2: Offsite tree planting, via an offset scheme. The ‘One Tree […]

Climate change adaptation and carbon emissions in green urban spaces: Case study of Adelaide

Concentrations of building mass and insufficient greenery in cities are identified to contribute significantly to extended heat stress in the built environment, commonly known as the urban heat island (UHI) effect. This paper presents a scenario-based modelling built on climate change projections and potential alterations of urban greenery in 2030 and 2090 in Adelaide, South Australia…

Urban agriculture could provide 15% of food supply to Sydney, Australia, under expanded land use scenarios

Highlights Sydney could grow 15 % of its food supply on verges, vacant land and 25 % of yard space. All required water and compost for soil amendment could be sourced from urban waste. Available amateur labour is insufficient to manage the land cultivated in these scenarios. A professional urban agriculture workforce may be viable,

CFD simulation of the drag effect of urban trees: Source term modification method revisited at the tree scale

Local air circulation is influenced by the drag forces exerted by urban vegetation. In this study, tree canopy parameterization in computational fluid dynamics (CFD) with source term modifications is conducted at the tree scale, which builds upon the models previously used in the literature…
