Revitalization of Urban Central Park
In 2001, the local municipality of La Paz, in collaboration with the International Union of Architects (UIA), launched a design contest to create a central park within a protected natural area (3). The park's aim was to develop urban infrastructure while connecting nature with the city (3). The winning architectural design envisioned an infrastructure that would harmonize with the existing natural surroundings and minimize interference with the environment (4).
The park's implementation included pedestrian and bike pathways, numerous panoramic viewpoints, facilities for exercise and cultural events, buildings dedicated to science, historically significant monuments, playgrounds, and the rehabilitation and creation of multiple green spaces (1 & 4 to 6).
While most of the project was completed by 2009, the area's exposure to recurrent landslides, droughts, and illegal waste disposal, combined with ongoing degradation, has necessitated afforestation efforts and maintenance actions from the municipality to ensure the protection of the natural area and enhance its benefits (7 & 8). Recently, the park has been part of a national citizen monitoring program for species, which has improved the categorization of wildlife in the area (11 & 12). Additionally, 2,000 trees were planted in the park in 2023 as part of a reforestation campaign, and cleaning and watering maintenance work has been carried out to support their growth (7 & 13). This initiative is part of a larger project to revitalize the park (10 & 13).
Overall, the park aims to protect local wildlife and plant species while acting as a "green lung" for the city, regulating the climate, providing recreational spaces, and improving livability (14).

Park at the triangular track
The Park am Gleisdreieck is a public urban park in the city centre of Berlin, spanning more than 30 hectares across three individual sites (Ostpark, Westpark, Flaschenhalspark) on former railway tracks. The landscape of the Park am Gleisdreieck is characterised by the central, extensive lawn and meadow areas, which are bordered by woodland-like areas - the so-called track wilderness - as well as various park trees and crossed by wide paths or old railway tracks. The park space features various recreational activities for sports and play as well as community gardens for intercultural exchange (Ref. 12). Being abandoned after WW II, the land rewilded and after being partially opened to the public in 2011, the primary aim of the maintenance and development measures was to harmonise the interests of nature conservation and recreational use. (Ref. 1; Ref. 3)
Many of the plant species in the Park am Gleisdreieck once travelled a long way by train. This is what makes the biodiversity in the park so special. It is a wild mixture of long-established Berlin plants and exotic species that specialise in dry, nutrient-poor soils. The park is part of Berlin's open space network, which extends from Tiergarten to Schöneberger Südgelände. It therefore makes a significant contribution to connecting habitats. (Ref. 1)
Initiatives of citizens have been working for years for the realisation of a park on the former railroad site at Gleisdreick, and so the residents have been involved in the park planning and design in an intensive dialogue process from the beginning and are still involved in the park management. (Ref. 2) The opening of the park served as a compensation measure for the construction of the urban development projects at Potsdamer Platz and aimed at increasing accessible green space in a densely and rapidly built urban environment.

Poppintree Park
Ballymun is a suburban area on the north side of Dublin, Ireland. Originally developed in the 1960s, Ballymun was built to address Dublin’s post-war housing shortages, with iconic high-rise towers and flat complexes. However, over the years, the area faced social and economic challenges, leading to a reputation for issues such as poverty, unemployment, and lack of services.
In response, the Irish government launched the Ballymun Regeneration Project in the late 1990s. As part of the Ballymun Regeneration, Poppintree Park has been transformed into a 45-acre public space at the heart of Ireland’s celebrated urban renewal project in Ballymun Town Centre. This redevelopment followed an extensive public consultation process, incorporating input from local residents, sports clubs, community groups, and youth organizations.
Poppintree Park now offers a range of upgraded amenities, including a Tree Trail featuring 15 native tree species, enhanced biodiversity, extensive wetlands, sustainable drainage systems, and spaces for passive and active recreation. The park also features a 1.25-acre playground for children aged 0-12, an amphitheater with a permanent pond, and a fully accessible pathway network with abundant seating and viewing areas. Over 50,000 plants have been added to enhance the park’s natural beauty.
The park’s transformation, led by Ballymun Regeneration Ltd., involved significant engineering and landscaping efforts. Mitchell + Associates provided the detailed landscape design, construction drawings, and supervised the landscape works.
Completed in 2010, Phase 1 of Poppintree Park’s redevelopment represents an investment exceeding €6 million. The project includes substantial earthworks, drainage systems, gabion walls, three limestone-paved entrance plazas, structural retaining walls, a cantilevered pond walkway, diverse path surfaces, and high-quality playground construction.

Afforestation of the Mallasa Landfill
This initiative was launched by the local government of La Paz, focusing on afforestation of the Mallasa landfill, which was closed in 2004 (1-4 & 6-10). While some plantations were established in the area when the landfill was closed, the overall plan aimed to manage the waste until the site was sufficiently clean for new projects—a process expected to take at least a decade (6). By 2021, signs of biodiversity, including flora and fauna, had begun to return to the former landfill. In response, the municipality of La Paz implemented a project to plant 6,000 native tree species, along with other shrub species, to further enhance biodiversity regeneration and establish a second urban forest in the city (3 & 4 & 7 & 8).
The afforestation efforts took place between 2021 and 2022, coordinated through "forestry brigades" made up of diverse volunteer groups. These groups included members from public institutions, private company representatives, NGOs (both environmental and non-environmental), universities, religious organizations, and local citizen groups (8-10). A total of 12 hectares were reforested out of the 33-hectare area (1 & 7). Following this, the area was closed to the public and is expected to become a biodiversity sanctuary within ten years, with ongoing monitoring by the municipal environmental agency (7). Among the trees planted, some were chosen to attract birds with their fruit, others to support the pollination of hummingbirds and bees, while others were intended to enrich the soil with nutrients—all species being native to the region (3 & 7).
Additional goals of the initiative include raising awareness about climate change, fostering a sense of environmental stewardship through community engagement, and advancing the municipality's decarbonization plans (3 & 9). Some of the seedlings and saplings were purchased by the municipality at a cost of 6,160 euros, with private companies also contributing financial support to the initiative (1 & 7).

Revitalization of Loma El Marion
The Loma del Marión recovery project in Cartagena, Colombia, is a community-driven initiative supported by EPA Cartagena that focuses on restoring and conserving the remaining 1.2 hectares of tropical dry forest. Initially covering 33 hectares, the area has suffered degradation due to illegal encroachments, deforestation, and waste burning. The project has included planting over 3,000 plants and fostering community involvement in environmental conservation (ref 1). The main goals are to restore the ecosystem by reforesting native species, preventing landslide risks, and developing an ecopark that will serve as an educational and recreational space. Planned facilities include a library for learning about local flora and fauna, hiking trails, and a community garden to enhance local food security (ref 1,4). A notable educational initiative in the project is the formation of "Vigías del Ambiente" (Environmental Watchers), a group of 40 youths from the Red Nacional Jóvenes de Ambiente, supported by EPA Cartagena and CDKN. This initiative educates young people on climate change, conservation, and waste management through workshops and activities (ref 2, 3). In addition, the EPA is leading detailed studies of the tropical dry forest to identify and protect endemic species (ref 5). The project has resulted in significant environmental and social benefits, such as planting thousands of trees, boosting community engagement in conservation, and establishing youth groups dedicated to sustainable development and climate action (ref 3, 5).
Extension of the Tagus Estuary Linear Riverside Park
The Tagus Estuary Linear Riverside Park is a significant environmental and recreational project in Vila Franca de Xira. As part of a broader urban regeneration initiative, the park aimed to enhance the natural and cultural landscape by promoting ecological regeneration while providing public access to the Tagus River (Ref 1). Created in 2013, the park has won several international awards and since then, the park has undergone several extensions. In 2017, another 700-meter walkway was added towards Santa Iria, and the inhabitants of this urban area of Vila Franca de Xira widely use it (Ref. 6). The park covers over 14 hectares and includes pedestrian and cycling paths, environmental education facilities such as the Bird Observatory, and the Environmental and Landscape Interpretation Centre (Ref 2).
Recently announced in 2023, the park's newest expansion is set to extend the riverside trails further, creating a continuous route from Lisbon to Alhandra (Ref 5). With future phases planned, the project is expected to significantly increase public interaction with the riverfront and its biodiversity (Ref 5). In this new project phase, the Vila Franca de Xira Municipal Council begins the requalification and environmental and landscape conservation of another section of the riverfront of the Municipality of Vila Franca de Xira, between Alverca and Sobralinho, covering an extension of approximately 4.9 km and an area of approximately 14.1 hectares (Ref. 7). The extension of the park will be developed similarly to its existing infrastructure. New paths for pedestrians and cyclists will be created using elevated wooden structures (walkways). In total, two new cycle-pedestrian trails will be created – Trilho das Comportas (3.32 kilometres long) and the Trilho dos Salgados (594 metres long) –, and the Trilho do Tejo will be extended by a further 990 metres (Ref. 5).

Al-Nasr Youth Center Seed Planting
In Egypt, knowledge about climate change remains limited, particularly among the younger generation. While all children globally face the challenges of a degrading natural environment and climate change, some are more vulnerable than others. This vulnerability is often influenced by the quality, availability, equity, and sustainability of essential services such as water, sanitation, healthcare, nutrition, and education. In response to these concerns, Egypt has taken steps to empower its youth to engage meaningfully in international efforts to combat climate change.
In 2022, with the support of UNICEF, the United Nations in Egypt, USAID, and the Embassy of Switzerland, Egypt's Ministry of Youth and Sports and Ministry of Environment launched the EGYouth4Climate Caravan. This initiative aims to raise awareness among children and young people about climate issues, encourage climate action, and provide a platform for youth to share their opinions and ideas. The caravan hosts a range of activities, including capacity-building sessions, youth dialogues, competitions, festivals, theatrical performances, bootcamps, and awareness campaigns.
One of the caravan’s stops was at the Nasr Youth Center in Alexandria, where a seed-planting workshop was held as part of the caravan’s reforestation activities. This workshop offered children a hands-on learning experience, teaching them about the importance of trees and providing an opportunity to plant seeds and trees across the center’s grounds. Through such initiatives, the EGYouth4Climate Caravan fosters climate literacy and environmental stewardship among Egypt’s youth, empowering them to take active roles in shaping a sustainable future.

Green Blue Axis of Sintra, Oeiras and Amadora
The Green and Blue Axis (Eixo Verde e Azul, EVA) is an inter-municipal green corridor project connecting the municipalities of Sintra, Oeiras, and Amadora through a 15-kilometre green ecological axis along the Jamor River (Ref 2). It aims to renaturalize the river, improve water quality, and control flooding while promoting sustainable mobility through pedestrian and cycling routes (Ref 5). The project also enhances public access to green spaces and cultural heritage sites, such as the Queluz National Palace (Ref 6). EVA supports the Lisbon Metropolitan Area’s regional strategy for climate change adaptation, risk prevention, and low-carbon economy (Ref 4). Funded by the European Regional Development Fund and municipal budgets, the project has an overall investment of €11 million (Ref 1). EVA exemplifies inter-municipal cooperation, overcoming policy conflicts to achieve shared environmental, social, and economic goals, making it a model for integrated territorial development (Ref 4). The project’s long-term impact includes reduced carbon footprint and increased territorial cohesion.
Metropolitan Lineal Park
The Metropolitan Linear Park is a project initiated by the national government of Bolivia, funded by the Inter-American Development Bank (IDB) (1-8). The proposed park will be located along a disused railway corridor between the cities of La Paz and El Alto, spanning 18.2 km (8, p. 8). The project involves the construction of a linear park, divided into five sections, each with distinct objectives, uses, and designs (8, p. 9). This large-scale initiative aims to improve access to public spaces in La Paz and El Alto, enhance connectivity between the two cities, protect surrounding biodiversity and natural spaces, and strengthen resilience to and mitigate the effects of climate change (3 & 8, pp. 11-12).
To achieve these goals, the project design includes outdoor sports and recreational facilities, pedestrian and cycling circuits, as well as the restoration of parks, squares, and public spaces adjacent to the park corridor (8, p. 9). Some features include balcony corridors, flower and food-producing urban gardens, and viewpoints (5). The project also plans for the re-vegetation of the area with native species and aims to stop the environmental degradation of surrounding natural environments, such as the Pura Pura forest, which has been suffering from ongoing deforestation and waste dumping (8, p. 9). These efforts are expected to increase and support biodiversity in the area (7 & 8, p. 12).
Additionally, the project emphasizes social inclusion, with policies designed to incorporate women, indigenous populations, and persons with disabilities (8, pp. 7-8). The park is intended to raise awareness about climate change and biodiversity, ultimately improving the quality of life and health of nearby residents and the citizens of La Paz and El Alto (8, p. 13).

Cypress Shore Park
A new park is being planned for the Cypress Shores area in Mobile (Ref 1). Five civil engineering students from the University of South Alabama contributed to the design of the park (Ref 1). This collaboration offers students practical experience while providing city designers with innovative ideas for the site (Ref 2). The design emphasizes sustainability and cost-effectiveness (Ref 3). The project will feature a small park and boat launch on a 5.6-acre plot (Ref 1) located within a residential neighbourhood (Ref 3).
The park's societal goal is to improve public access to Halls Mill Creek, giving the community a new way to enjoy the waterway, and this focus aligns with the Mobile Bay National Estuary Program (MBNEP) goals (Ref 3). Historically, the property was used as a shipyard with a nearby railroad crossing (Ref 1), marking its transition from an industrial site to a public park.
Several amenities have been identified for the park’s development, including a boat ramp and kayak launch, a boardwalk adapted to sea-level rise, a pavilion and gazebo designed for flood resilience, a wetland nature trail with solar lighting and educational signage, and composting toilet restroom facilities (Ref 3). An armoured shoreline will be implemented to withstand medium water currents, and wave action will be constructed. Additionally, a living shoreline will be restored with local plants (Ref 3). While the project is still in its preliminary design phase, the timeline for completion is estimated at 12 to 18 months (Ref 1). The designers highlighted a potential trade-off, noting that an influx of visitors to the park could disturb the surrounding residential area (Ref 3).
