Increased provisioning of ecosystem goods (e.g. Food, water, etc)
Yes
Increased infiltration, water retention and flood protection
Yes, tree cover significantly increases soil infiltration rates and storage thereafter, reducing runoff and helping to mitigate flooding (Zhang et al., 2019). The newly created wooden area, with a surface of 30,000 m2, will contribute towards reducing the risk of flooding through implemented sustainable urban drainage systems (SUDS) that prevent runoff of water and flooding and, at the same time, increase soil humidity.
Improved air quality
Yes, the wooded area will improve air quality by increasing vegetation cover over an area of 30,000 m2 which was previously devoid of arboreal vegetation.
Reduced drought risk, cooling effect, urban heat island mitigation
Yes, the increase of evapotranspiration in cities, derived from vegetation, urban agriculture, and water bodies, can effectively mitigate the effect of urban heat islands (QIU et al; 2013). In this context, measures such as increasing the volume of irrigation water and the surface of wooded areas of a territory are essential for mitigating temperature increase and stopping the process of desertification, as urban centers are important heat source and these green areas are able to significantly reduce the local temperature, reduce erosion and naturally increase the water reserve of a territory. (lifeadapte, 2021).
Biodiversity conservation or increased biodiversity
Yes, an increase in wooded areas permits an increase in biodiversity.
Ecosystem restoration and/or improved ecological connectivity
Yes, through the implementaton of a green zone.
Increased quality and quantity of green and blue infrastructures
Yes, by increasing tree cover, which is expected to contribute to an improved urban ecosystem services capacity.
Sustainable urbanisation
Yes, the project plays an essential role in sustainable growth and the increase of ecosystem services. This newly created wooded area may be considered as a urban sprawl garden in Águilas. It can be considered as an urban expansion area, mainly due to the fact that this area was previously classified as a green zone in the urban planning regulations for the municipality.
Improved aesthetic value
Yes
Creation of green jobs relating to the construction and maintenance of NBS
Yes, the creation of this new area involved manpower, and its maintenance will imply an increased demand on human resources within the public garden maintenance service.
Increased access to green infrastructure
Yes
Increased willingness, participation, investment in NBS
Yes, with the construction of this forest area, the concept of public gardens has changed. From now on, the design of public gardens will take into account the use of endemic species with a low demand for water resources and a high adaptive capacity, instead of introduced exotic species.
Provision of health benefits
Yes, urban green interventions play an important role in creating a culture of health and wellbeing (Hunter at al; 2019).
Education, knowledge exchange and learning
Yes, this action is aimed at creating an informative space.
Low provisioning of ecosystem goods (e.g. Water, food)
Yes, this wooded area requires a low demand for drinking water because all irrigation water comes from urban wastewater treatment.
Flooding risk
Yes
Low air quality
Yes
Drought and heat risk
Studies have shown that heat and drought waves in Europe are induced by the Mediterranean rainfall deficit (Vautard et al; 2007). This region has been subject to frequent and extensive forest fires in recent years. Based on future climate scenarios, the frequency and extent of large wildfires will increase throughout the Mediterranean Basin (Ruffault et al; 2020). Drought impact on society can be very high, being one of the natural disasters that cause more economic damage. The lack of water intensifies erosion, since the air and water drag away the surface particles of the soil, which leads to the loss of this fertile and protective layer. Thus, the regeneration of the vegetal cover becomes increasingly slower. In this context, measures such as increasing the volume of irrigation water and the surface area of wooded parts of a territory are essential for mitigating temperature increase and stopping the process of desertification, as urban centres are a significant heat source and these green areas are able to significantly reduce the local temperature, reduce erosion and naturally increase the water reserves of a territory. (lifeadapte, 2021).
Loss of biodiversity
Yes, the resulting occurrence of recurrent forest fires is a key factor in the impoverishment of biodiversity in forest ecosystems.
Ecosystem degradation
Yes, the region suffers from intensified soil erosion with a great impact on agriculture which it is the main source of Águilas's economy. (lifeadapte, 2021).
Low availability of green infrastructure
Yes, the very forest-friendly nature of the project has resulted in the use of the least possible resources for the necessary infrastructure elements. This area has benches, descriptive panels and overhead covers, all made of wood from environmentally friendly sources.
Good health and well-being (SDG3)
Yes, the SDG3 is well-represented in this project through an ideal circuit for outdoor sports, which also has a section of cycle path that runs longitudinally through the forest area, which also has several rest areas with shaded benches.
Clean water and sanitation (SDG6)
Yes, by promoting the saving of safe drinking water, as it has vegetation with low watering demands and an irrigation system based on the reuse of urban wastewater.
Industry, innovation and infrastructure (SDG9)
Yes, the use of new technologies have been implemented, mainly concerning the reuse of treated wastewater using photovoltaic solar energy and a system for remote control of the physico-chemical parameters of this recycled water.
Sustainable cities and communities (SDG11)
Yes, urban trees are passively subject to and actively mitigate urban environmental pressures. They perform important urban ecosystem services and play a key role in contributing to sustainable cities. (Lüttge, Buckeridge, 2020).
Climate action, resilience, mitigation and adaptation (SDG13)
There is great demand for water which has intensified due to the incipient growth of the population (more than double the usual population) during the holiday season in summer and the enormous amount of water needed to carry out the main activity of the Águilas economy, which is agriculture. Droughts impact on society can be very high, being one of the natural disasters that cause a greater economic damage. The lack of water intensifies erosion, since the air and water drag the surface particles of the soil, which lead to the loss of this fertile and protective layer. (lifeadapte, 2021).
Terrestrial biodiversity (SDG15)
Yes, this project supports the representation of typical biogeographical habitats of the Mediterranean region, thanks to the availability of a significant volume of treated water which, if not reused for irrigation of public gardens, would flow into the Mediterranean Sea.
