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)

The first medicinal plant library in Martinique was created by the Ypiranga Martinique association, which inaugurated the project in 2019. The initiative was developed to preserve and revitalize traditional knowledge of medicinal plants in Martinique, integrating agroecology , modern scientific understanding, and ancestral practices.
The project is located on land provided by the municipality in the Tivoli neighborhood, and it serves as an educational resource, a functional pharmacy, and includes a small shared vegetables garden. Visitors, local residents, and researchers can access information on over 150 native Caribbean plants and their medicinal properties. The site includes two educational trails: one following the river that crosses the garden and a sensory trail designed to help visitors "reconnect with nature." Each plant is identified with information boards detailing its medicinal uses, including whether these uses are scientifically validated.
The project also aims to address social exclusion by offering reintegration workshops to troubled teenagers and the unemployed.
The project was financed through a combination of sources: an EU-funded call for projects, a crowdfunding campaign, and regional and national public subsidies.
As a result of its success, in 2021 the initiative was formally replicated with the support of the Caribbean Interreg "OSAIN" project, which led to the creation of 14 additional plant libraries in schools and public spaces. Volunteers and community-based efforts continue to sustain the project, and it has become a model for similar initiatives. (Ref. 1,2,4,5,6,7)

The BASIC Cartagena Project is an applied research initiative focused on developing tools for integrated coastal water resource management in Cartagena, Colombia (ref 4). It is funded by the International Development Research Centre (IDRC) of Canada, and EAFIT University leads it in collaboration with the University of Los Andes, the University of Cartagena, the Foundation H.E.O., and the Regional Corporation CARDIQUE (ref 4). The goals are to reduce pollution, conserve ecosystem services, and implement climate change adaptation strategies in the coastal area (ref 3). The studies focus on Cartagena Bay (Recognized as the most polluted body of water in the Caribbean), the Dique Canal and the Magdalena River watershed, the local communities in the areas surrounding Cartagena Bay, principally the communities of Ararca and Barú (ref 5). During its first phase (2014-2017), the project concentrated on diagnosing pollution levels and sources. This included extensive monitoring of water quality and the socio-economic conditions of local communities (with a public health focus). The second phase (2018-2021) focused on developing early warning systems for pollution, educational programs, and knowledge transfer through community engagement. The third phase (2023) plans to expand the same activities from phase 1 & 2 to the Rosario and San Bernardo Islands, with continued collaboration among scientists, authorities, and local communities​ (ref 2, 3). Among its most significant achievements are the production of high-level scientific knowledge and the training provided to communities and environmental authorities. A notable impact of the project is its contribution to the formulation of seven policies, including the creation of an intersectoral committee for the environmental management of the Bay of Cartagena. This committee, for the first time, brings together various stakeholders, including fishing and tourism communities, to make decisions about environmental management (3)

Liquid 3 is the first urban photo-bioreactor in Serbia, developed by an interdisciplinary team at the Institute for Multidisciplinary Research at the University of Belgrade (Ref. 1,2,3). Prompted by an appeal of the United Nations Development Programme (UNDP), the team was eager to find novel approaches to combat the city's severe air pollution issues while being space efficient and providing year-round benefits (Ref. 3). The key to the bioreactor are algae which are very efficient in sequestering carbon and filtering heavy metals from the air (Ref. 2). A Liquid 3 feature can be quickly set and occupies a plot of only 3 m². Some of its benefits include its ability to withstand high levels of air pollution and its ease of installation on surfaces like walkways and other sealed infrastructure (Ref. 2,3). Additionally, by design, Liquid 3 integrates amenities such as power outlets, a bench, and nighttime lighting (Ref. 1). The selected strain of algae can tolerate temperatures between 5-35°C making it deployable all year. However, monthly maintenance is required, during which the water and algae are replaced—both of which can be repurposed, for example, as fertilizers (Ref. 6).The project has received global media coverage as well as a prize for the best innovative and climate-smart solution in Serbia. Its success has prompted the installation of two more such bioreactors in Serbia, with interest coming from other countries such as Hungary and the UAE (Ref. 1,4).

The World Health Organization estimates that 80% of the population in developing countries use medicinal plants for health prevention and care, primarily in rural areas (3). These plant species have therapeutic potential in treating various diseases, and they are considered safe and effective medications with fewer side effects and affordable prices (3). In Peru, medicinal plants have historically been used to treat respiratory, gastrointestinal, and digestive ailments. To this day, they continue to be used by both native and urban communities (3).
To promote, develop, and encourage research, innovation, and technologies related to the use, preservation, conservation, and employment of medicinal and food plants, the National Center for Social and Intercultural Research in Health (CENSI) of the National Institute of Health (INS) has inaugurated its medicinal and food plant nursery located in one of its facilities (Chorrillos) in Lima (1, 3). The primary objective of this project is to adapt various species from the coast, mountains, and jungle of the country and initiate a plant production program that contributes to improving public health, environmental quality and the revitalization of the ancestral knowledge of indigenous, Amazonian, Andean, and Afro-Peruvian communities (1). Additionally, it aims to contribute to mitigating the effects of climate change by creating green areas, reducing atmospheric carbon dioxide levels through plant photosynthesis, improving soil quality, and promoting the responsible use of water resources, among others (3).
For the development of this project, the INS is working in collaboration with the International Organization for Migration to benefit not only the health and well-being of the Peruvian community but also promote the integration and care of the migrant population in the country (2).

A new addition has enriched Gdańsk's green spaces: the park at Szubieniczna Mountain near the Gdańsk University of Technology. This area, located behind the cutting-edge STOS building housing the "Kraken" supercomputer, has been transformed into a vibrant urban oasis. Covering approximately 7,500 square meters and costing 3.5 million zlotys, the park introduces a sustainable and welcoming environment for students, residents, and visitors alike.
The park aligns with the university's PG Climate Plan, a strategic initiative promoting environmental sustainability through research, education, and green infrastructure. Historically a neglected area with overgrown trees and bushes, it has now been revitalized to create a functional and aesthetic space that merges ecological values with public utility.
Key features of the park include over 1,500 new plantings—trees, shrubs, and flowers—that enhance biodiversity and create a visually appealing landscape. Ecological innovations such as a rain garden and energy-efficient lighting reflect the park's commitment to sustainability. Recreational and educational facilities include a mini amphitheater, an outdoor gym, and walking paths interspersed with gravel squares surrounded by flower meadows.
A new pathway connects the campus to Szubieniczna Hill, granting access to Gdańsk's largest water reservoir and offering stunning panoramic views. This transformation underscores how urban green spaces can address climate challenges while improving quality of life for the community. The Szubieniczna Mountain Park is not just a park—it’s a symbol of progress toward a greener future for Gdańsk. (1-2)

The Chaowan Nursery Garden Base Project (潮玩苗圃基地), located along the Dianchi Greenway in Kunming, was established by the Kunming Gardens Virescence Bureau (昆明市园林绿化局) in 2022 as part of the city's efforts to transform into a "city of parks" (Ref 2, 3). Covering 639 mu (42.6 hectares), the Chaowan Nursery Garden has introduced over 1.4 million plants, including trees, flowers, and grasses, greatly expanding the city's green spaces (Ref 3). It serves as a key resource for the Kunming Greening Service Center (昆明市绿化服务中心), providing seedlings for major greening projects along roads like Guangfu Road, Airport Road, Beijing Road, and the Second Ring Elevated Road (Ref 4).
Innovatively designed, the nursery also functions as a park, offering an "immersive" experience with various themed areas such as rainwater gardens, rural gardens, Chinese gardens, and scenic balconies. These spaces allow visitors to stroll through and enjoy the beauty of various flowers and natural surroundings (Ref 4). The project also collaborates with local universities on seedling research, capacity building, and resource sharing, further enhancing its multifaceted role (Ref 3).
Since opening to the public in 2023, the Chaowan Nursery Garden has become a popular destination for families, young people, and children, offering both recreational and educational experiences (Ref 5, 6, 7, 8).

A green area was turned into a "reuse park" to save trees, bushes and other plants that had to be moved from elsewhere due to construction work. The project resulted from constructing the new business school at the University of Gothenburg, where circular economy initiatives are being tested. Plants that would have to be removed from that site were moved to the park at Medicinareberget temporarily. They will later be replanted elsewhere on campus, saving money and reducing the environmental impact of buying new plants. The lead actor in the project is the public real estate company Akademiska Hus, which owns and manages the affected parts of the university campus. The reuse park was established in 2021, and it's implied that it can continue to function as a storage site for plants from different construction locations. The project is highlighted as a learning opportunity for how the reuse of plants can be implemented in future construction projects. The project is connected to the regional initiative Återbruk Väst within the national platform CCbuild, which promotes circular solutions in the construction centre [Ref. 1-5].

The Rain Garden 2.0 project at Gdańsk University of Technology is an innovative green infrastructure initiative that manages and purifies rainwater while enhancing biodiversity. Part of the international NICE (Nature-based solutions for urban climate adaptation) initiative, this project serves as a living hub for testing solutions to address urban climate challenges. Opened in July 2023, the rain garden exemplifies a multifunctional approach to water retention, pollutant filtration, and urban biodiversity support. It is located behind the Faculty of Chemistry's Building C and has a capacity exceeding 11 cubic meters. (Ref. 1; Ref. 6)
The garden, designed by researchers from the Faculty of Civil and Environmental Engineering under the leadership of Prof. Magdalena Gajewska, captures rainwater runoff to prevent urban flooding and mitigate the strain on storm sewer systems. It absorbs pollutants, improves water quality, and supports over 1,100 hydrophyte plants, creating a natural solution for heavy rainfall events.
Beyond water management, the garden contributes significantly to urban biodiversity. Its moist soil and diverse plant species—designed to thrive in a range of conditions—help create habitats for insects and other small wildlife, boosting ecological resilience. (Ref. 1)
The rain garden’s innovative design consists of several key components. The first stage channels rainwater into reservoirs, reducing the energy of inflowing water. Subsequent parts purify the water through sedimentation processes, effectively filtering out pollutants such as those from streets and roads. Early research shows that these purification methods work exceptionally well, retaining a broad spectrum of pollutants before the water reaches the garden’s main basin. The project also benefits from cutting-edge laboratory equipment, allowing for detailed monitoring and analysis of water quality. (Ref. 1)

The "Line Park" project in Belgrade aims to create a continuous green belt spanning 4.6 kilometres and covering over 48 hectares. As such, the project will revitalize the former railway corridor from "Beton Hala", just below the Belgrade Fortress, to the Pancevac Bridge. Inspired by notable urban parks like New York's "High Line", Moscow's "Zagrađe," and Toronto's "Rail Corridor," it will become a major recreational destination and also help to alleviate the pressures from the city's heavy air pollution and summer heat (Ref. 5, 6).
The park will be divided into ten thematic sections dedicated to aromatic plant and flower gardens, urban gardening and beekeeping, sports facilities, a newly built university campus and more. Additionally, there will be an amphitheatre and facilities for outdoor education. To further integrate green infrastructure, new buildings will have green roofs and walls (Ref. 2,5). Ultimately, the park integrates a number of amenities into the entire city.
The development of the park also introduced innovative co-creation mechanisms in terms of governance and planning. Since Belgrade is part of the multinational CLEVER Cities Initiative, the city's Secretariat for Environmental Protection suggested the use of the site as a pilot test for introducing nature-based solutions in urban planning and with diverse stakeholders' input. Several workshops, focus groups, and consultations took place between 2019 and 2021, which facilitated the diversity of ideas that have been adopted into the official construction plan (Ref. 1, 2). Despite these successes, civil society groups raise concerns over the extraordinary cost of 70 million euros, displacement of Roma communities and the interest of real estate developers that may undermine the project's original cause (Ref. 3, 8).
