As cities grapple with the impacts of heatwaves, exacerbated by the urban heat island effect and progressively amplified by climate change impacts, green spaces can cool urban areas, as well as providing many other functions and benefits to city dwellers’ health and wellbeing. Public policies can contribute to retaining and maximising urban green spaces.

In a study of green space policies in Melbourne and in London, policy success – developing, endorsing and implementing policies that effectively contribute to urban green space provision – differs across jurisdictions and between cities, but common factors were identified. Conversely, the lack of these factors contributed to less effective implementation. These success factors include both organisational and individual policy maker’s characteristics.
