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.
Biodiversity conservation or increased biodiversity
Increased quality and quantity of green and blue infrastructures
Yes, by increasing tree cover which would be expected to contribute to an improved ecosystem services capacity (Balzan et al., 2018).
Drought and heat risk
The Mediterranean Region is considered as a "hot-spot" of climate change, having been identified in global climate scenarios as one of the most responsive regions to climate change (Lionello and Scarascia, 2018). There is a consensus in scientific literature that average temperatures will rise across most of the Mediterranean Region, and that precipitation will decrease (Ulbrich et al. 2013; Lionello and Scarascia, 2018). Observed annual mean temperatures in the Mediterranean Region are now 1.4 °C higher than the average late-nineteenth-century levels particularly during the summer months (Cramer et al., 2018).
Loss of biodiversity
Yes, whilst improvements have been recorded for several species and habitats, Malta’s biodiversity continues to experience various pressures and threats (ERA, 2018d), including land development, invasive species, over-exploitation of species and climate change. (Malta Voluntary National Review on the implementation of the 2030 Agenda, 2018).
Low aesthetic value
Terrestrial biodiversity (SDG15)
Yes, this action increased tree cover at the Mizieb woodland. Only around 0.7% of Malta's land area is covered by forests (ERA, 2018a).
