Achieved increased green space area

The Parco della Musica in Cagliari, inaugurated in 2011 by the municipality of Cagliari, blends modern urban design with a focus on green spaces, music, and culture. Spanning approximately five hectares, the park features a small, winding artificial river that flows from north to south, creating a micro-habitat for various bird species. This waterway, lined with benches on the western side and open green spaces on the eastern side, offers a peaceful setting for both wildlife and visitors. The use of native plants, trees, and shrubs further enhances the biodiversity.

In terms of construction, the use of sustainable materials like marble paving and wooden platforms reflects a commitment to modern design. This makes the Parco della Musica an ideal venue for hosting events and fostering social interaction where culture can thrive, and people can relax and enjoy fresh, calm spaces. Overall, the Parco della Musica serves as an example of how modern urban spaces can be designed to promote ecological balance while offering cultural and recreational benefits to the community (Refs. 1, 2, 3, 4 & 5).

The "Parco degli Anelli" is a new green space project in Cagliari, located along the waterfront in the Sant'Elia district. Designed by Portuguese landscape architect João Ferreira Nunes and inaugurated in 2019, the park spans approximately 15 hectares, with over 4 hectares currently accessible to the public. The remaining area will undergo renovation in the next two phases of the project. The park is notable for its open design, free of walls and fences, and its direct access to the sea, making it a unique addition to the city's green spaces (Refs. 1, 2 & 7).
This park exemplifies urban renewal by transforming a previously neglected and degraded area into a green, accessible to all public space. It is part of a broader context of redevelopment of peripheral neighborhoods, in this case the Sant'Elia district.(Refs. 6 & 9).
Parco degli Anelli features flat terrain with numerous pedestrian and cycling paths for individual sports activities, along with expansive grassy areas covering about 27,000 square meters. The park is surrounded by approximately 500 newly planted trees and shrubs typical of Mediterranean maquis, including Aleppo pine, dwarf palm, European olive, and jacaranda.
Future plans for the park include expanding into additional areas and connecting it to the rest of the city via a pedestrian and cycling bridge over the Palma Canal, as well as connecting it to the new waterfront promenade that is being built from Via Roma to Marina Piccola (Refs. 1, 2 & 7).

The Praderas de Vida garden is an initiative to transform a former rubbish dump into a source of employment and empowerment for the residents of the Praderas de San Juan de Miraflores Human Settlement (1). This agroecological community garden was developed as part of ISA REP's Sustainable Easements programme (13), located in the easement area of Peru's energy network, and it has collaboration efforts with KUNAN, Misha Rastrera, and La Muyita, brings together twelve female heads of households who cultivate, harvest, and process a variety of medicinal plants that have aromatic, antiseptic, and relaxing properties (2, 3).
Beyond agricultural production, the garden has become a hub for emotional and economic support, fostering a connection with nature through plant care and interaction with the local ecosystem (3). It has also led to the establishment of a social enterprise, "Praderas de Vida," allowing women to participate in agroecological fairs to market the products derived from the medicinal plants grown in the garden (3).
The garden has evolved into a space for learning and community collaboration, promoting the importance of sustainability and biodiversity conservation (6).

The reforestation project at Bela Vista Park in Lisbon is a collaborative effort by the MEO Kalorama music festival, the Lisbon City Council, and Quercus (local NGO). The intervention began with a community planting event in February 2024 with the planting of 80 native trees, and the goal to plant a total of a total of 1,000 trees. The project aimed to improve the park's biodiversity, enhance carbon absorption, and support local wildlife. The tree species were chosen for their suitability to the local climate and their ability to integrate with existing vegetation. Local schoolchildren and residents participated in the planting, serving as a community engagement activity. This initiative is part of broader efforts to make Lisbon greener and to positively contribute to the local environment, given the disturbance caused by the MEO Kalorama festival (Ref 1, 2, 3).

The park called Järnvågsparken will be constructed in the developing neighbourhood of Masthuggskajen as the main green space of the area, measuring about 8000 m2. The park will offer recreational activities for people living and working in the area, with spaces designated for rest, meetings, picnics, walking and play. For example, there will be a large playground, many different places to sit, grass lawns and a space to host cultural events in [Ref. 1-4]. The park will also be designed to manage stormwater and reduce flood risk [Ref. 5, 6]. The park will be built over an existing highway, turning it into a tunnel while reconnecting the new neighbourhood. The remaining future park area next to the road are currently parking spaces [Ref. 1, 4, 5]. The adjacent streets will also see more greening, increasing the connectivity of green spaces and mobility [Ref. 4-6]. The location on top of a tunnel limits the soil depth of the park, but the ambition is still to house a rich plant and animal life, including trees, providing ecosystem services [Ref. 1-6]. The project is managed by the City of Gothenburg [Ref. 1, 7].

The project, implemented by the municipality of Cagliari, involves the creation of a new garden in 2021 on Via Eroi d’Italia, in the Pirri municipality, located about 5 km from the center of Cagliari. This initiative is part of a broader effort to reclaim degraded urban green spaces. The garden spans approximately 900 square meters and was previously an unused lot serving as a parking area. Its transformation required substantial groundwork, including soil scarification and leveling, to prepare the area for its new purpose. The garden is now enclosed, with pedestrian access via two gates leading to a paved walkway.
Inside, the garden is divided into two main sections: a children's play area and a landscaped green space. The play area covers about 100 square meters and features durable artificial grass, swings, a spring toy, a universally accessible table, a children's table, benches, and a multi-compartment recycling bin. The green space, approximately 200 square meters, is planted with low-water-use grass and surrounded by drought-resistant plants like albizia, oleander, and lantana, chosen for their low water consumption and resilience to environmental stress. An underground irrigation system, linked to a 5,000-liter water tank, ensures efficient water use.
The remaining 600 sqm outside forms a parking area with 1 disabled space, 2 motorcycle spaces, 1 bicycle rack, and 15 car spaces.
The garden also incorporates sustainable elements, such as LED lighting for energy efficiency and a mural by renowned Sardinian artist Manu Invisible, depicting sunlit forest undergrowth in shades of green. This project responds to citizens' requests and prioritizes resource efficiency by reducing hazardous substances and minimizing waste. The materials used, including recycled plastics, and the selection of plants were chosen to match local ecological conditions, enhancing the garden's sustainability and reducing its environmental impact (Refs. 1, 2, 3, 4 & 5).

Earthworks Urban Farm, located on Detroit's east side, is a pioneering initiative of the Capuchin Soup Kitchen that integrates sustainable agriculture, social justice, and community development. The Capuchin Soup Kitchen is a religiously affiliated soup kitchen and non-profit organization located in Detroit, Michigan. It was founded by the Capuchin friars to provide food for the poor during the Great Depression and is sponsored by the Capuchin Franciscan Province of St. Joseph. The farm was founded in 1998 by Brother Rick Samyn, and began as a small garden focused on educating local youth about healthy food and its origins. Over time, this modest garden expanded into a 2.5-acre urban farm, including 1.5 certified organic acres—making it Detroit's only certified organic farm.
The farm’s growth included adding a large plot behind its partner, Gleaners Community Food Bank, as well as establishing an apiary with up to 40 hives, a greenhouse for transplant production, a hoop house for year-round crops, and a community orchard. Earthworks' work has evolved along with its physical space, significantly extending its reach.
A wide variety of vegetables are cultivated here without herbicides or pesticides, with harvests distributed to local residents and included in meals at the Capuchin Soup Kitchen, ensuring fresh, nutritious food for those in need. Beyond agriculture, Earthworks serves as a community hub, engaging volunteers, offering educational tours, and supporting thousands of community gardens across Detroit with transplants and expertise.
Committed to evolving its programs, Earthworks has experimented with mobile markets, community-supported agriculture (CSA), and local market stands, demonstrating its dedication to meeting community needs through sustainable practices.

The Çukurova University Botanical Garden was initiated in 1972 by the Department for Landscape Architecture to protect and conserve the rich native and non-native biodiversity of the region for future generations (Ref. 5,9). Its establishment responds to the lack of Botanical Gardens in Türkiye despite the country's great diversity. The Garden also wants to offer protection for increasingly threatened species in the face of rapid and uncontrolled urbanization (Ref. 5,9). Being located close to two Deltas and an important agricultural region, the collection also aims to include a great number of wetland and agricultural species, drawing public attention to the importance of these ecosystems (Ref. 6). As such, the University invites every school in Adana to visit and participate in its ongoing educational activities and primary school children are offered hands-on gardening programmes (Ref. 1,2). Furthermore, visitors can immerse themselves and learn about various vegetation zones, including endemic maquis, where stairs, walking paths and information boards have been installed (Ref. 4). The University maintains research activities in the Botanical Garden and in on site laboratories, which regularly host interns (Ref. 4). To ensure the stready supply of plant material for landscaping and education, nurseries have been set up and in 2020 a 250 m² medicinal and aromatic plant greenhouse was added where students of the Faculty of Agriculture are trained and endemic species grown (Ref. 9,10).

The Phoenix Park initiative was carried out by the "Gheorghe Asachi" Technical University of Iași in partnership with the Iași Communitarian Foundation, the BorgWagner Fund, and the Municipality of Iași. It involved the rehabilitation of a green space within the university campus. Covering an area of 3,000 square meters, the renovation was based on the winning design from a student competition focused on improving campus spaces.
The park was designed to include facilities for physical exercise (calisthenics equipment), recreation (badminton court and ping-pong table), and social interaction spaces. It also serves as a buffer to reduce noise from the surrounding areas.
The total cost of the project amounted to 121,200 euros, with the university covering infrastructure expenses, the municipality providing the labor for rehabilitation, and the private fund contributing 15,150 euros. The implementation of the design was overseen by the student designer and coordinated by the NGO and the university’s Association of Student Architects.
This initiative is part of a larger urban regeneration project by the university, in collaboration with the municipality and the Communitarian Foundation, where several campus green spaces are being rehabilitated based on student designs. The overarching goal is to enhance students' quality of life and promote healthy lifestyles through the creation of green spaces during their time at the university. (1, 2, 5, 6, 8, 13, p. 92)

Phoenix is one of the hottest cities in the United States, with temperatures regularly exceeding 40°C (104°F) for more than 90 days each year. The urban heat island effect is severe here, posing a significant health risk. Many communities in Phoenix lack equal access to shade cover—often, the impact of extreme heat disproportionately affects low-income neighborhoods that lack resources for tree planting and maintenance. In contrast, wealthier areas tend to have more trees and are visibly greener, which helps reduce the heat residents experience.
To address these disparities, the City of Phoenix partnered with SRP, a not-for-profit public power utility, to launch the "Right Tree, Right Place" program in 2018. This initiative aims to bring shade relief to areas most in need, such as parks, public transit stops, and schools, while replacing older trees that interfere with SRP power lines. SRP and the city work together to identify trees that pose risks to overhead power lines, and for each tree removed, three new trees are planted—either in a different location or with a species better suited to coexist with power lines.
One of the program’s notable projects took place in West Phoenix’s Cortez Park, where 24 drought-tolerant trees from four different species were planted. This diversity helps protect the trees against pests and other natural threats, ensuring their longevity and resilience. Through initiatives like these, the "Right Tree, Right Place" program contributes to Phoenix’s larger goal of developing a robust, biodiverse urban forest. By expanding green infrastructure, the city aims to reduce local temperatures, improve air quality, and create cooler, healthier neighborhoods for all residents. (1-8)
