Urban green space cooling effect in cities
Aram et al. (2019) conducted a systematic review of research studies on how improved urban green spaces create a cooling effect and reduce the ground level temperature. The review searched for articles that critically discussed the relationship between reduced ground level temperature and urban green spaces. From this study, it was deduced that urban green spaces with an area of 0.5-2 hectares can only reduce the temperature by up to 0.3 °C over a distance of 40 m, whereas those with an area of 3-5 hectares may reduce it by up to 0.7 °C over a distance of 70–120 m.
