Exploring the interrelationships between urban form and air quality

This thesis examines how urban form—specifically factors like the built environment, green spaces, and economic activity from the perspective of compactness—affects local air quality, focusing on particulate matter concentrations in Melbourne. Through various analytical methods, it demonstrates that pollution sources and green infrastructure exert a more significant influence on air quality than urban density or compactness alone. The findings encourage policymakers to address pollution sources comprehensively, considering their generation, dispersion, and exposure impacts, while prioritising green space enhancement. This approach supports sustainable urban development that safeguards public health and fosters environmental resilience amid rapid urbanisation and population growth.
