NY12018 - Greening Neighbourhoods - Mitigating Heat Stress with Vegetation

In Australia’s major cities, population growth and rapid development has led to the transformation of many urban landscapes, resulting in engineered infrastructure dominated by heat absorbing surfaces. This heat accumulation can cause the ambient temperature in urban areas to be several degrees higher than that of nearby rural areas, known as the urban heat island (UHI) effect. In summer, the risk of heat-related health impacts in urban areas may be further exacerbated by climate change, as heat waves are projected to increase in frequency, intensity and duration. These multiple and interacting factors present enormous challenges for governments, industries and communities.
