Improved air quality
Yes, tree and woodland cover was associated with air quality improvement ecosystem services (Balzan et al., 2018).
Reduced drought risk, cooling effect, urban heat island mitigation
Yes, trees and plants provide shade and reduce the urban heat island effect.
Sustainable urbanisation
Yes, Urban green spaces (UGS) provide multiple benefits, and public parks in particular have a key role in supporting ecological and social sustainability in cities, contributing to human-nature interactions (Vierikko et al; 2020).
Increased access to green infrastructure
Yes, provision of a pleasant green space for enjoyment.
Provision of health benefits
Yes, the importance of trees in urban areas has been associated with the provision of valuable environmental services to combat challenges such as pollution, urban heat, and flooding, as well as to improve social cohesion, human health, and well‐being (Cavender and Donnelly, 2019). Urban Green interventions has an important role to play in creating a culture of health and wellbeing (Hunter at al; 2019)
Low air quality
Yes, urban trees help to improve air quality by facilitating widespread deposition of various gases and particles through the provision of large surface areas as well as through their influence on microclimate and air turbulence (Grote et al; 2016).
Drought and heat risk
Yes, the Mediterranean Basin is undergoing a warming trend with longer and warmer summers, an increase in the frequency and the severity of heat waves, changes in precipitation patterns and a reduction in rainfall amounts (Linares et al; 2020).
Low availability of green infrastructure
Yes, densely populated urban areas were characterised by a lower availability of green infrastructure (Balzan et al. 2018).
Sustainable cities and communities (SDG11)
Yes, increasing urban greenery are intended to make the city more sustainable through the provision of cleaner air and reduction of ambient temperatures and soil erosion.
