Benches and drinking water stations

Tempelhofer Feld stands as an innovative green solution in the heart of Berlin, addressing several issues of environmental justice, biodiversity, and urban resilience. Within the S-Bahn ring, only one in 20 residents lives in areas well-served by green spaces, and districts like Neukölln, Kreuzberg, and Tempelhof would face even greater scarcity without this vast expanse. Many residents in these neighborhoods lack access to private green spaces such as gardens or balconies. Without nearby parks, people are compelled to travel to other districts, exacerbating the congestion of green spaces and increasing local traffic.
Since its opening in 2010, Tempelhofer Feld has provided Berlin with over 300 hectares of open, green, leisure, and recreational space, making it one of the largest urban open spaces globally. Once the site of bustling air traffic, it is now a sanctuary for activities such as skating, strolling, gardening, picnicking, birdwatching, kiteboarding, and more. These wide-ranging uses showcase its transformation into an accessible, multifunctional green space that serves as a social equalizer, particularly for disadvantaged neighborhoods, a significance amplified during the Covid-19 pandemic.
The field is not just a recreational haven but also a vital ecological refuge. With over two-thirds of its area designated as green space, it hosts diverse ecosystems, including extensive natural meadows, lawns, and protected habitats for birds and other species. Certain areas are closed to the public to preserve these sensitive environments, emphasizing the balance between human activity and ecological conservation. Since 2019, animal landscape keepers, including around 100 resident sheep, have contributed to sustainable land management practices, promoting biodiversity and ecological health (Ref. 2).
Managed collaboratively by political, administrative, and societal actors, the site exemplifies integrated citizen participation in urban planning. (Ref. 3)

The Upper Detroit Riverfront Habitat and Parks Restoration Project aims to restore and enhance vital fish and wildlife habitats along the Detroit River. This initiative seeks to rehabilitate approximately 30 acres of upland and shoreline habitats within Riverfront-Lakewood East Park, A.B. Ford Park, and Mariners Park (all located alongside the river), covering nearly one mile of the Detroit River and its shorelines.
Key outcomes include improving approximately 1,000 linear feet of existing shoreline along the Detroit River by incorporating native wetland edges and fish spawning shelves into the restoration efforts. The project also plans to enhance around 2,000 linear feet of canal shoreline and 800 linear feet along Fox Creek to create or improve habitats for fish and herpetological species. In Riverfront-Lakewood East Park, 28 acres are targeted for the establishment or enhancement of native vegetation to support birds, mammals, and pollinators. If feasible, the creation of about 7 acres of wetlands, along with shallow and deep-water habitats, is also part of the vision.
The project is guided by the City of Detroit's 2017 Parks and Recreation Improvement Plan and represents part of a broader strategy to revitalize the city’s green spaces after years of underfunding. With renewed commitment, the city has allocated nearly $12 million to enhance neighborhood parks, particularly in areas that have lacked investment over the past decade.
However, the project was temporarily halted in 2020 due to high water levels causing flooding in the adjacent neighborhood. As of 2024, it remains on hold while the City of Detroit conducts a flood mitigation study. Despite this delay, the project remains a critical step toward fostering community stewardship and creating sustainable green spaces that improve the quality of life for all Detroit residents.

Historically, the area of San Paolo in Cagliari has suffered from environmental degradation and illegal dumping, making it an unsightly entrance to the city. In 2022, the Città Metropolitana di Cagliari, initiated a project to transform this degraded area into a urban park featuring 7,000 new plants, including olive trees, junipers, lentisks, myrtle, rosemary, tamarisks, and Aleppo pines. Managed by the municiplaity of Cagliari, and funded by a €500,000 grant from the Ministry of Ecological Transition, this initiative will cover 4.7 hectares between Via San Paolo and the Santa Gilla Lagoon, creating a natural corridor connecting the city to the lagoon. The project aims not only to restore the land but also to enhance both metropolitan and municipal environmental requalification plans.
A multidisciplinary team, including a forestry technician, agronomist, and biologist, developed the project to ensure it is environmentally sustainable and suited to the local ecosystem.
The work on the project began in June of 2022 with land preparation, removal of invasive species, and waste collection, resulting in the clearing of over 5 tons of rubbish. By December, around 3,000 plants had already been planted, with the remaining work, including the installation of an irrigation system, scheduled for completion by January 2023. The selected plant species are fast-growing, and within two years, the shrubs are expected to reach a height of about two meters. The park is planned to open to the public in 2024, providing a new green space for walking and outdoor activities.
The San Paolo urban park project has encountered obstacles, mainly due to the expropriation of buildings, leading to legal disputes, permit delays, and a temporary halt caused by a tender-related issue. The site is currently overgrown and unused, showing clear signs of neglect. (Refs. 1, 2, 3, 4 & 5).

The Africatown Connections Blueway project aims to create a recreational water trail by linking 14 culturally and historically significant points along a 10-mile route (Ref 1). Central to this initiative is the preservation of Africatown's rich heritage and natural resources. The project seeks to reconnect residents of Africatown, descendants of the original founders of this self-governing community, which maintained a strong sense of African cultural heritage, to waterways that were historically vital for food, transport, and spiritual practices (Ref 1). By restoring access to these waters, the community can address both environmental and social issues, promoting eco-tourism and business growth while safeguarding cultural heritage (Ref 2). Local leaders emphasize the environment’s role in healing the community and preserving history, highlighting how this initiative can provide economic opportunities and improve quality of life (Ref 2). The project seeks to address the environmental injustices that Africatown communities have endured for decades. The area surrounding Africatown has long been dominated by harmful industries, including aluminium plants and paper mills, which have heavily polluted the water and restricted residents' access to it (Ref 1). With support from the National Park Service and contributions from Mississippi State University, the Blueway transforms neglected river access points into recreational areas, promoting environmental stewardship and cultural awareness (Ref 2).

In 2017, many public parks in Iași were in poor condition, suffering from neglect and inadequate maintenance. Parks like Barboi were left unmanaged, with deteriorating infrastructure and overgrown vegetation. In response, the municipality of Iași initiated efforts to revitalize these green spaces.
The Barboi Park revitalization focused on rehabilitating 8,200 sqm of a degraded area (1 & 6, p. 106). Accessible pathways were repaired, and benches were installed to create a relaxing environment (1 & 4). Existing trees and vegetation were pruned, new trees and ornamental plants were introduced, and the soil was enhanced with more fertile layers to correct uneven levels (1 & 4). The primary aim of the new vegetation was to improve the park’s aesthetic appeal and boost biodiversity (1).
The project was led by the Municipality of Iași through its Public Services Department (Servicii Publice Iași), which oversaw the improvements (1 & 6, p. 106). It was part of a larger urban plan to expand and enhance the city’s green spaces (6, p. 106 & 7, p. 336). This plan aimed to improve the city’s visual appeal and increase livability for residents (6, p. 106). The project’s total cost was approximately €260,450.45 (6, p. 107). Later that year, the park was renamed "Woodrow Wilson" to commemorate the 100th anniversary of the U.S. mission to Iași during WWI, with a small monument erected to mark the occasion (5). The initiative also aligned with national guidelines on green space regeneration, per capita green space, and accessibility (7 & 9).

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 Green Corridor Südpanke is a transformative restoration project that unveiled 700 meters of the river Südpanke, connecting Invalidenpark and Südpankepark in the heart of Berlin. This initiative, part of Berlin's broader mission to restore the Panke River, was spearheaded by the state of Berlin with a focus on ecological restoration, biodiversity enhancement, microclimate cooling, and creating recreational spaces to improve the quality of life for residents (Ref. 2; Ref. 3).
Historically, the river in this area was channeled underground. The project brought the Südpanke back to the surface, integrating ecological principles and landscape planning into the design. The restored section of the river now flows openly in a natural watercourse bed, making it accessible to the public (Ref. 5). The restoration was completed in 2021, transforming the area with features such as playgrounds, lawns, benches, and a continuous biking and walking path that weaves through the green spaces.
Work on the project began in 2010 but was interrupted by the construction of the neighboring headquarters of the Federal Intelligence Service. As a result, parts of the green corridor were opened to the public in 2012, with the full restoration completed nearly a decade later, in 2021 (Ref. 3; Ref. 6).
The project established a seamless connection for cyclists and pedestrians from Invalidenpark in the south to Südpankepark in the north. The new open water section cools the microclimate in Berlin's densely built-up center while providing a critical habitat for plants and animals. Embankments and meadows near the Federal Intelligence Service's property support wild bees and other pollinators, fostering biodiversity. The Green Corridor Südpanke is a vibrant example of how urban ecological restoration can contribute to sustainability, quality of life, and resilience in a growing city. (Ref. 2)

Brookley by the Bay is a 98-acre new waterfront park project along Mobile Bay's western shore (Ref 1). The park aims to reconnect people with the Mobile waterfront and coastal ecosystem (Ref 2). The area, once an abundant mosaic of tidal marshes, forested wetlands, and shallow lagoons, became a port, leading residents to lose contact with the natural landscape (Ref 2).
The park serves both recreational and environmental purposes, aiming to create and restore areas that enhance habitat resilience and allow coastal ecosystems to thrive (Ref 1). It features sports facilities, including kayaking, volleyball, golf, and biking, along with social gathering and educational spaces such as an amphitheatre lawn, a performance pavilion, and picnic tables (Ref 3, Images 1-3). The park provides safe and equitable access for all Mobile residents to nature, beaches, tree canopies, open fields, and varied shorelines, all connected by pedestrian and bike lanes (Ref 2). The project also focuses on habitat enhancement and restoration for biodiversity (Ref 3, Images 1 & 4), as well as flood protection through shoreline get-downs, vegetated edges (Image 4), and undulating berms and swales that serve as a layered protection system against stormwater and coastal flooding (Ref 2).
The development of Brookley by the Bay was guided by input from over 300 community members (Ref 1), local stakeholder organizations, and project partners, with the goal of establishing a more resilient, accessible, and enduring space for generations to come (Ref 2).

The PARK(ing) project, completed in April 2022, is an urban private intervention in Core City neighborhood in Detroit, that re-imagines a vacant 24,000-square-foot lot into a dual-purpose public park and a 28-car parking lot. Designed by Julie Bargmann of D.I.R.T. Studio, in collaboration with Prince Concepts and in-house landscape designer Andrew Schwartz, this innovative green space harmonizes urban infrastructure with natural elements. The site is punctuated with 78 newly planted trees, including sumac, maple, and evergreen species, creating an environment rich in vegetation that seamlessly integrates with its urban surroundings.
The design incorporates permeable pavers and sloped berms, which effectively manage storm-water by absorbing and channeling rainwater, mitigating the risk of flooding—an often-overlooked challenge in traditional parking lots. This approach reflects sensitivity to the local environment and a commitment to sustainable urban design.
By day, the park discreetly functions as a parking facility, with cars nestled among dense greenery, while by evening, it transforms into a public garden, extending the communal space of Core City Park. This dual functionality addresses the needs of a car-dependent community while promoting walkability and enhancing the neighborhood's ecological footprint.
PARK(ing) exemplifies a shift in Detroit's urban planning, moving away from the car-centric developments of the past toward a more balanced relationship between people, nature, and infrastructure. The project stands as a testament to the evolving identity of American cities, particularly those like Detroit, historically shaped by the automobile. It offers a vision of urban spaces that prioritize community well-being and environmental stewardship while acknowledging the realities of modern urban life. (Ref. 1, 2)

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)
