: This underground garage in Alicante Spain was provided with special treatment “with a green roof makeover". The garden is ultra low‐maintenance and doesn't require any irrigation at all. It is located in a relatively protected area, within the inner courtyards and at the entrance of the building, and this feature has enabled a rise in the number of species and an increase in the variety of colours “that would otherwise have been more limited in a more exposed area”. (IUCN, 2019; Naturvation project, 2019).
Increased infiltration, water retention and flood protection
Yes, green roofs can slow down runoff generation, and therefore contribute to providing flood protection benefits to the surrounding areas.
Improved air quality
Yes, this vegetable cover boosts air quality (IUCN, 2019).
Reduced drought risk, cooling effect, urban heat island mitigation
Yes, this vegetable cover serves to decrease the ambient temperature in the patios and houses in summer. (IUCN, 2019).
Biodiversity conservation or increased biodiversity
Yes, this garden has led to an increase in the number of species (IUCN, 2019).
Increased quality and quantity of green and blue infrastructures
Yes, introducing green space into the built environment.
Yes, enhancing natural capital in the built environment. The green roof helps to cool the underground area cooler further and embellish the location. (IUCN, 2019).
Improved aesthetic value
Yes, this vegetable cover contributes to the landscape aspect of the building and embellishes the location. (IUCN, 2019).
Provision of health benefits
Yes, this vegetable cover not only serves to enhance the landscape aspect of the building but also improves air quality and serves to decrease the ambient temperature in the patios and houses in summer. (IUCN, 2019).
Low air quality
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).
Low availability of green infrastructure
Low aesthetic value
Yes, the green roof is located on the underground parking.
Good health and well-being (SDG3)
Yes, urban greenery contributes significantly to human well-being.
Sustainable cities and communities (SDG11)
Climate action, resilience, mitigation and adaptation (SDG13)
