Using integrated urban models to respond to climate change in cities

Power resources Climate change Urbanisation Australia New South Wales

This paper presents a single, integrated urban model that focuses on the key areas of transport, domestic energy-use, and domestic water use and how these relate to urban planning and other policies. 

The model structure is spatial — requiring a sub-division of the urban region into disjoint sub-regions.  Such a sub-division is necessary, not only because spatial information is essential to any transport model, but also because climatic and demographic factors are common to all resource models, and are spatially heterogeneous.
The model is intended for use by local, regional, and state authorities, government departments, energy, and utility service companies as a modelling and decision support tool for analysing the impact on cities of a range of energy, water, transport, and land use related policies.  In particular, it seeks to understand the impact-reductions possible at household and city scales.  Growing awareness of the threats from climate change has focused attention on greenhouse gas (GHG) emissions and the need to reduce them.  
Using a sample analysis of Sydney, our on-going research collaboration seeks to examine the working relationships between multiple infrastructure sectors through a single analysis platform.  The need to integrate policy for multiple infrastructures is critical given the multiple fronts on which the sustainability of urban systems are now jeopardised.
