Tulla Urban Farm
Tirana's urban development has set a new record in 2022, when more than 1.8 million square meters of new buildings were constructed (Ref. 5). This rapid development increased the need for accessible urban green areas. At the Tulla Urban Farm, a wide audience is trained to create those green areas in their yards, balconies and roofs with the added benefit of growing produce for their own needs (Ref. 1,2,5). This practice of food autonomy is deeply rooted in Albanian culture but has been lost in urban settings where concrete has taken over the city (Ref. 1). Tulla Urban Farm addresses this issue by providing an inclusive space for people of diverse backgrounds to come together and experience urban gardening first hand under the guidance of professionals from the Agricultural University of Tirana (Ref. 2,3). In these "urban agricultural schools", workshops, seminars and discussions are held to re-cultivate traditional agro-cultural practices and knowledge that will benefit the participants, many of which are from marginalised backgrounds (Ref. 1, 4). All these activities are facilitated through the rooftop greenhouse of the Tulla Cultural Center, which harbours over 300 plants (Ref.1). As such, Tulla Urban Farm not only provides a space for experiencing and learning about plants but also for social interaction and building a community that also addresses more serious issues such as mental health in a society that faces high rates of unemployment (Ref. 1).
The project had received inital funding from the German GIZ in 2022 and won the Cultures of Resistance Award through which it financed the first two years of its programme and enabled free participation at the urban agricultural school for all participants (Ref. 2,4).

The Pantanos de Villa Wildlife Refuge
The Pantanos de Villa Wildlife Refuge is a natural oasis in the heart of Lima. It is considered a marsh of international Ramsar importance, as it is home to a large number of species of flora and fauna. It includes 5 bodies of water with about 210 species of birds, 13 species of fish, and 5 species of amphibians and reptiles, among others (1). It was created in 2006, by Supreme Decree N°055-2006-AG, which established the definitive category for the Pantanos de Villa, under the name of The Pantanos de Villa Wildlife Refuge (2). This protected area was established over an area of 263.27 ha, and its main goal is to conserve a representative sample of the Marshes of the Subtropical Pacific Desert, including important plant communities, as well as migratory and resident avifauna, focusing mainly on species with some degree of threat (1, 2, 6).
In 2016, a Master Plan was approved aimed at strengthening the conservation of the biological diversity of this coastal marsh and ensuring conditions to promote inter-institutional cooperation and participatory management, including neighbours, authorities, municipalities and interested institutions (2).
This Master Plan establishes environmental, economic and cultural indicators defined to be met over 5 years. These are focused on protecting water resources, conserving migratory and resident bird species, ensuring the conservation of the cattail, promoting tourism and recreational activities, fostering environmental awareness activities and engaging citizens in the management of the Refuge (2)
This plan seeks to confront a series of threats that endanger the conservation of this ecosystem. Among the main problems are the illegal extraction of natural resources, such as cattail; the improper use of the space for activities such as bonfires, consumption of illicit substances and pet walks; the change in land use due to urban expansion; pollution from effluent discharges and solid waste disposal; and illegal fishing (2)

Thessaloniki's New waterfront
Thessaloniki, Greece's second-largest urban center, is a key hub for economic growth and outward trade in the Balkans. The city hosts the country’s second-largest export port, which plays a crucial role in connecting European trade routes with Asia and China. However, until 2014, Thessaloniki's waterfront was poorly maintained, largely inaccessible, and unattractive. Moreover, major flooding events, connected to extreme weather events, exposed significant deficiencies in the city's flood mitigation infrastructure, leading to damage to housing and critical services. (5, 10, 11)
To address these issues, the Municipality of Thessaloniki launched an International Architectural Competition for the redevelopment of the New Waterfront. From 2006 to 2014, Thessaloniki's waterfront underwent a significant regeneration aimed at benefiting the city's population of 1.1 million and stimulating the local economy. The revitalized waterfront now stretches 3 kilometers between land and sea, featuring 58,000 acres of green space an playgrounds.. In total, 2,353 new trees and 118,432 plants were added across an area of 238,800 m² (Refs 1, 3, 4).
The project also introduced walking routes, sports and recreational facilities, seating areas, and scenic viewing points. The waterfront now has a bicycle path along the entire walkway, and an arbour of 660 umbrella pine trees, serving as shade from the midday sun. Completed in 2014, the New Waterfront has already become a vibrant urban green space, enjoyed by both Thessaloniki's citizens and visitors alike (Ref 4).

Westwood Tree Planting
Minimizing heat stress is a top priority for Phoenix, the hottest major city in the U.S. In 2023, extreme heat contributed to at least 359 deaths across Maricopa County. Phoenix is particularly vulnerable to climate change, with extensive concrete and asphalt, increased pollution, higher population densities, and concentrated infrastructure that exacerbate the urban heat island effect, drought, and extreme weather. Moreover, the heat disproportionately impacts lower-income and Hispanic neighborhoods, which tend to have less tree canopy and fewer resources to cope with rising temperatures.
To address these challenges and promote tree equity in underserved neighborhoods, the City of Phoenix, along with the Office of Heat Response and Mitigation, launched the Community Canopy Grant Program in 2023. The concept of tree equity refers to identifying areas with low tree coverage and high social need, then prioritizing investments in these areas. By improving tree equity, the program aims to assist neighborhood associations and community members in areas that need it most.
The Community Canopy Grant Program targets neighborhoods within Qualifying Census Tracts across Phoenix, and one of the first neighborhoods to benefit was Westwood. In early 2024, community members gathered to plant 200 box trees for residents who received grants, marking the largest City-sponsored neighborhood tree planting event of the season. These tree plantings aim to provide much-needed shade for homes while fostering community engagement, helping to mitigate heat stress and build stronger, more resilient neighborhoods. (1-5)

"Rain garden" along the October 28th street in Thessaloniki
The 28th of October Street (28ης Οκτωβρίου) was one of the most neglected streets on the eastern side of Thessaloniki, completely devoid of trees despite its central importance. Additionally, the street suffered from severe flooding during heavy rainfall. In 2011, the Municipality of Thessaloniki, in collaboration with Konstantinos Zervas, the Deputy Mayor for the Environment, Quality of Life, and Free Space, proposed a redevelopment project aimed at transforming the street through the planting of trees and the installation of flower beds that would function as rain gardens (Refs 3, 5). This initiative was part of the "Integrated Green Cities" action, which falls under the European territorial cooperation program Greece-Bulgaria 2007-2013 (Refs 1, 2, 3, 6).
To achieve the dual goals of sustainable rainwater management and urban beautification, decorative trees were planted in specially constructed bioretention tree stands. These stands, along with the flower beds, were designed to collect rainwater, which would then be used to irrigate the trees along the road and the plants forming the rain gardens. Rainwater was gathered from the road surface, pavements, and the gutters of apartment buildings through these bioretention systems (Refs 1, 2). This sustainable water management solution significantly reduced rainwater runoff, improved water quality, and enhanced the area’s aesthetic appeal (Refs 2, 6, 7).

Tree Plantation Month
The "Tree Plantation Month" is an annual national initiative in Romania, organized by the Ministry of Environment, Water, and Forests through the National Directorate of Forests. This initiative focuses on afforestation, forest regeneration, and raising awareness about the ecological benefits of forests, while promoting sustainable behaviors (4, 9, 10). Having been in place for 60 years, the program has recently aligned with the principles outlined in the 1991 Paris Declaration on the Sustainable Development of Forests (10). At the national level, the initiative is regulated with overarching goals aimed at protecting and sustainably managing Romania's forests (9). The program allows for the involvement of various actors, including public institutions, municipalities, NGOs, and schools, who collaborate with regional forestry directorates to implement local activities (4).
In 2019, as part of this initiative in Iași, the Asociația Tineretul Ortodox Român Iași (ATOR), a youth-led religious association, actively participated in one of the campaigns . They planted 1,000 tree saplings in the Moara de Vânt district, an area that had suffered from deforestation and was prone to landslides (1, 2). The afforestation efforts were designed to address these environmental challenges by stabilizing the soil, reducing the risk of overflow and flooding, maintaining soil moisture, and regulating extreme temperatures (1). To ensure long-term success, the saplings were regularly monitored, and restoration efforts were carried out in cases where the trees were affected by fires or drought (3).

South Hennepin Marsh Habitat Restoration
The South Hennepin Marsh habitat restoration project, located below the Grosse Ile Toll Bridge causeway, within the Detroit River's Trenton Channel near Grosse Ile, Michigan, aims to restore and protect one of the region's most critical wetland habitats. This emergent marsh, historically vital for fish and wildlife, has suffered significant degradation due to river currents, boat traffic, and winter ice flows. The project, identified as a priority in the 2002 Habitat Protection and Remediation report for the Detroit River, encompasses the restoration of over 1,000 linear feet of protective shoals and 20 acres of productive wetlands, home to various native plant species such as rushes and submergent macrophytes.
The primary goal of the project is to stabilize and enhance the marsh's habitat, improving conditions for fish, waterfowl, reptiles, amphibians, and other wildlife. Restoration activities include the placement of approximately 10,000 cubic yards of rock and soil to rebuild eroded shoals, installation of erosion matting, and re-establishment of native vegetation. Additional habitat features, including habitat logs, mudpuppy structures, and stone spawning beds, will provide crucial breeding and feeding areas for species such as walleye, northern pike, and lake whitefish.
The project also incorporates soft engineering solutions, such as fallen branched trees and strategically placed stones, to support pollinators, birds, and reptiles. Feasibility studies and design plans were completed by Environmental Consulting and Technology, with funding from NOAA, and construction was carried out by E.C. Korneffel Company beginning in 2021. The project reached completion in November 2022, successfully restoring the shoals and protecting the marsh from further degradation. These efforts have significantly enhanced habitat availability, ensuring the sustainability of the South Hennepin Marsh as a critical ecological site within the Detroit River system.

Renovation of Tapolca nature park
Miskolctapolca is a district of Miskolc and features a nature park (which includes a lake, Csonakazo-to) originally planted in the 1920s using the exotic trees and bushes. In 2022 the municipality decided to renovate the area under a EU funded project called "Creating a Green City in Miskolc-Tapolca". The project aimed to establish a modern urban green space focused on active recreation for various age groups, enhancing Miskolc's appeal for tourism.
The renovation included new concrete paving system and updated utilities for the lakes' promenades with a strong emphasis on accessibility ensured smooth mobility throughout the area. The renovation added informative signs detailing local attractions, historical trees, and the park's history. To enhance visitor comfort, a new accessible restroom was constructed. Renovations to the Csonakazo-to lake included removing accumulated silt and reinforcing the shoreline, alongside the addition of new street furniture, lighting, and wooden sunbathing terraces and platforms. The two bridges around the lake were renewed, and the squirrel installation, a favorite among locals, were restored. Furthermore, a square in the park, Kilátó Square was transformed with benches and drinking fountains, creating a welcoming space for relaxation.
Additionally, extensive landscaping was carried out, including the planting of approximately 100 trees, 9,000 shrubs, 18,000 perennial plants, 2,300 annuals, 350 roses, and 6,600 bulbs.
The surrounding park, which had been in disrepair for decades, was thoroughly revitalized, blending traditional and modern aesthetics. This long-overdue renovation significantly enhanced the environment. The construction was carried out by FEDRID Építőipari Kft., starting in spring 2022, and was completed in May 2023 after some delays.

Shared gardens in vulnerable neighbourhood
Terres Sainville is one of Fort-de-France's priority neighborhoods, known for the precarious living conditions of its residents and the prevalence of illicit activities. Many plots of land in the area have been abandoned and are used as informal dumpsites. In response, the City of Fort-de-France developed the "Jaden Lanmou" (Garden of Love) program, which aims to revitalize neglected spaces across the city’s 145 neighborhoods, Terres Sainville being one of them.
With support from the Terres Sainville town hall, neighborhood associations (such as the Terres Sainville Citizens' Council and local schools), and the Ypiranga Martinique association, the community has been working to transform these wastelands into shared gardens. Since 2021, Ypiranga has created 10 productive gardens, designing each based on the land's configuration, soil quality, and the preferences of local residents, including options for market gardening, medicinal plants, fruit trees, and above-ground containers (Ref 1; 7).
This initiative prioritizes the development of city-owned land and strategic transit sites, while also encouraging private landowners to maintain their abandoned plots or share them with the community. Additionally, the program seeks to enhance existing flowerbeds, create new ones, and incorporate artistic elements like street art and graffiti. Public meeting spaces are being developed to foster community interaction.
The city aims to involve residents by providing equipment, training, workshops, and advice on best practices. Ultimately, neighborhood representatives and residents will be responsible for maintaining these new communal spaces and ensuring they are respected (Ref 2).

Horvath-hill recreational green area development
The "Active Recreational Green Area Development at Horváth-tető" in Miskolc is a project aimed at revitalizing a central yet underutilized urban space, commissioned by the Municipality of Miskolc in 2017. A distinctive feature of Miskolc is the Avas hill, located in the city center, which beautifully blends nature with urban elements. Despite its potential, the area had been neglected, particularly following the decline of vineyard culture and the reduced use of old wine cellars. To address this, a comprehensive development plan was initiated to rejuvenate the Avas region, with Horváth-tető at its core.
The project aimed to transform the area into an outdoor recreational hub for all age groups. The hill's historic terraces, once popular promenades, were repurposed into distinct, multifunctional spaces. Sports enthusiasts can enjoy facilities such as street workout stations, an outdoor gym, a skate park, a climbing wall, and parkour elements. For those looking to relax, picnic areas, sunbathing spots, and a retro-style terrace are available. The entire development prioritizes accessibility, providing inclusive options for visitors with mobility challenges.
The park also features significant landscaping, including the planting of trees, shrubs, perennials, ornamental grasses, and ferns, enhancing its overall appeal. Infrastructure improvements were made, including the restoration of stairs, paths, retaining walls, and the rainwater drainage system. A special shallow basin was designed to collect rainwater and support plant roots while also serving as a playful area for dogs within the dog park.
Since its opening in 2022, the park has become a popular destination, offering a tranquil escape in a beautiful setting. It provides a wide range of recreational opportunities for people of all ages, making it a valuable addition to Miskolc’s urban landscape and connecting the historical Avas hill with modern city life.(Ref.1,2)
