Evaluating the effectiveness of the urban forestry as an UHI mitigation strategy at city scale
(2010 – current)
Darien Pardinas Diaz
The increment of temperatures in the urban ecosystems due to the urban heat island phenomenon brings about important environmental, social and economic implications: increased energy consumption, elevated emission of air pollutants and greenhouse gases, compromised human health and thermal comfort and impaired water quality. The green infrastructure has the potential to mitigate this additional heat, but its cooling effectiveness needs to be quantified at different time scales in order to support heat mitigation programs at neighbourhood and city scale.
The aim of this PhD project is to study the potential of the urban forestry for heat mitigation taking into consideration the existing urban vegetation infrastructure, the physical constraints for further increment and the underlying climate of the target city. A combination of remote sensing imagery classification, urban planning information, GIS techniques and local-scale urban climate modelling will be used as primary tools. Expected outcomes include a comprehensive description of the temporal and spatial variability of the cooling effectiveness in two Australian cities (Melbourne and Brisbane) with contrasting climate characteristics.
