Rings Park
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).

Medicinal Garden ‘Meadows of Life’
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).

Görömböly sandwall European Bee-eater habitat
The Görömböly European Bee-eater Habitat Protection Project, launched in 2002 in Miskolc-Görömböly, Hungary, is a key conservation initiative dedicated to protecting 26.5 hectares of critical habitat for the highly protected European Bee-eater (Merops apiaster) and the Sand Martin, along with the diverse ecosystems thriving in this area.
The site comprises three unique zones: an abandoned sand quarry, a young acacia woodland, and a quarry lake surrounded by marshlands. The sand quarry’s vertical walls provide nesting sites for 15-40 European Bee-eaters and Sand Martins each year, supporting Red-listed species vital to Hungary’s biodiversity. The acacia woodland serves as a feeding ground, while the quarry lake nurtures a rich aquatic ecosystem, hosting protected species like the European Bitterling fish, amphibians such as Green Toads, and a variety of waterfowl, including Mallards, Little Grebes, and occasionally Kingfishers.
This project not only safeguards these vulnerable species but also fosters community engagement, offering residents the chance to learn about local wildlife and ecosystems. Additionally, the initiative promotes scientific study of the area’s ecological development, contributing valuable insights into species behavior and habitat evolution. With an emphasis on nature education and recreation, the project raises public awareness of environmental conservation.
The Municipality of Miskolc plays a crucial role, having designated the area as a protected site and managing its regulatory enforcement and maintenance.

Filter Ecosystem in Molentargius
The Filter Ecosystem project, completed in 2007, aims to improve water quality and enhance the ecological health of the Molentargius wetland area in Sardinia, Italy, also known as the Molentargius Saline Regional Nature Park. This diverse territory includes freshwater basins such as Bellarosa Minore and Perdalonga, saline water basins like Bellarosa Maggiore and Stagno di Quartu, and the predominantly dry area known as Is Arenas.
The Molentargius ecosystem is a crucial European site for various aquatic birds and features diverse flora, including endemic species and endangered plants on the "Red List." It is one of the few globally recognized wetlands of international importance for aquatic birds located entirely within a large urban center, protected as a biotope by the RAMSAR Convention in Sardinia's major urban area. Since the 1980s, it has suffered environmental degradation due to inadequate infrastructure for wastewater management and human pressures.
Implemented by the city of Cagliari, the project employs a phytoremediation technique to supply water to the ponds. This involved constructing a phytoremediation system between the Bellarosa Maggiore and Bellarosa Minore ponds, functioning as a surface flow filter ecosystem resembling a marsh or wetland.
The system enhances natural self-purification processes, promoting prolonged contact between water, organic matter, and plants. This setup creates microhabitats that support microbial flora crucial for purification. The project's primary goal is to treat wastewater from the Is Arenas treatment plant, ensuring that the treated water meets optimal conditions for sustaining the wetlands' biodiversity. Additionally, the project will expand reed bed areas, vital habitats for avian species, and is designed to purify up to 300 liters of water per second to meet the area's needs (Refs. 1, 2, 3).

Green Area - Via Eroi d'Italia
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
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.

Cuihu Lake Restoration
In the 1980s, rapid industrialization, urban population growth, and increased water usage led to severe pollution in Dianchi Lake, exceeding its environmental capacity and significantly degrading its water quality (Ref 1). This deterioration had serious effects on nearby ecosystems, including Cuihu Lake (Ref 2). Cuihu Lake (翠湖), also known as Green Lake Park, is a well-known park and body of water in the center of Kunming, Yunnan Province, China. In Cuihu lake the decline in water quality caused a sharp reduction in native species like the golden line barb, which depend on the local ecosystem for survival, pushing them to near extinction and destabilizing the entire ecosystem (ibid.).
To address this, several effective initiatives have been launched to restore Cuihu Lake’s ecosystem in recent years (Ref 2, 3). One of them was started in 2020 when a restoration project was initiated by the site's administration in collaboration with Dr. Li Weiwei’s team from the Kunming Institute of Zoology, Chinese Academy of Sciences. The project focused on creating micro-habitats and restoring the aquatic ecosystem (ibid.). Ecosystem and biodiversity restoration efforts were conducted across a 5,000 m² area on the east side of Green Lake Park, covering approximately 1/27th of the lake (ibid.).
As a result, more than 20 aquatic animal species are now thriving and contributing to water purification, while three submerged plant species cover over 50% of the project area (Ref 2, 3, 4). Bird diversity and numbers are also increasing, with species like white-breasted kingfishers, green-winged teals, and crested guinea-fowls returning to the area (ibid.). Additionally, there has been a significant improvement in water quality (ibid.).

Härlanda biodiversity park and farm
A small biodiversity park was established in Härlanda Park, an old prison complex which today houses a culture centre, a pre-school and office space. The area was previously used as a small lily garden, but this project implements more biodiversity-promoting features such as a bee hive, varied flowers and trees, different types of soil and insect hotels. The municipal real estate company Higab owns the park and partnered with Stadskupan, which works with urban beekeeping, biodiversity, and rewilding, to design and create the park. They also involved Vägen ut! (translates to "the way out"), a social enterprise that employs people who are far from the labour market due to substance abuse issues to help maintain the park in a socially inclusive way. The park has pedagogic features and events for local businesses and organisations as well as the public. The beehive was established in 2022, while the entire biodiversity park was established in 2023. The project will go on for three years and be evaluated yearly. [Ref. 1, 2, 3].
Phoenix Park
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)

Pedagogical Arboretum in schools
This project, implemented in several schools across Fort-de-France in 2018, focuses on creating arboretums in schools to educate children about Martinique's native natural heritage and raise awareness of biodiversity loss. An arboretum is a curated collection of trees selected for scientific, conservation or public enjoyment.
The initiative, led by the Martinican National Botanical Conservation, is supported technically by the municipal landscaping department and administratively by the city of Fort-de-France and the Martinican School Rectorate. It includes three main activities: a seminar on Martinique's rich yet fragile botanical heritage, an excursion into a forest, and a tree planting event at schools featuring native or endangered plant species. The program has reached at least six schools in and around Fort-de-France.
