The "Há Vida no Meu Bairro" project is an innovative urban initiative led by the Lisbon City Council aimed at transforming the city into a "15-minute city." This concept ensures that all essential urban functions, such as commerce, green spaces, education, sports, culture, health, and social support, are within a 15-minute walk from residents' homes. The project promotes neighbourhood identity, quality of life, active mobility, and the development of safer, more comfortable public spaces. By integrating these elements, the initiative seeks to create multifunctional neighbourhoods where daily needs can be met locally, reducing dependence on cars and enhancing pedestrian accessibility (Ref 1).
Lisbon's approach is both city-wide and neighbourhood-specific, with pilot projects being developed in collaboration with the city's 24 parishes. These projects focus on improving public spaces and pedestrian mobility, reinforcing the city's commitment to sustainability and community engagement (Ref 2). The initiative also emphasizes the importance of public participation, encouraging residents to contribute to the design and development of their neighbourhoods and enhancement of local identity and green spaces (Ref 3).

The "Parque Espíritu del Manglar" in Cartagena is a multi-zone public space designed to promote recreation, environmental awareness, and cultural identity. The park, which has undergone a significant reconstruction, offers a wide array of recreational equipment and spaces for contemplation in a natural setting. It is divided into six thematic zones: Entrance Zone; Sports Area, Open-Air Theatre, the Tertulia Island, offering scenic views, public restrooms, and statues such as the iconic "Macondo" tree, a tribute donated by Gabriel García Márquez’s family; Children’s Central Zone, featuring a pirate-themed mangrove ship and an Environmental Observation Deck. (ref 1).
With the reopening of the park, EPA Cartagena introduced an ecological trail on Tertulia Island, where a mangrove restoration process has been carried out, focusing on plant health and climate resilience. This area also hosts wildlife such as macaws, sloths, turtles, raccoons, and green herons—species that cannot be reintroduced into their natural habitats. (ref 2)
The park now serves as an active site for environmental education, particularly for children, with programs addressing solid waste separation, climate change, and the protection of natural resources. Its reopening has also been recognized as a key step in strengthening family-oriented tourism and promoting sustainable urban development in Cartagena. (ref 2)

The project features a vertical garden, or "living wall," on the facade of a residential building in Berlin’s Kreuzberg district. Constructed in 2016, the building replaced a WWII-damaged plot situated between two existing structures. With a strong emphasis on sustainability, the project minimizes its ecological footprint in various ways. The 660-square-meter plot retained original elements of the location’s history: the two surviving sections along Glogauer and Reichenberger Strasse were restored after the war, while the rubble from the destroyed corner was used to fill in the basement. This approach allowed the new construction to be built over the original foundations, preserving historical integrity while reducing construction costs and material use.
At the core of the building’s design is a green agenda, embodied in the vertical garden that helps absorb noise and pollution from the bustling street below, improving air quality for residents and passersby. The selection of winter-hardy plants ensures that the facade remains green year-round, while also cooling the surrounding area and mitigating the urban heat effect, which is especially valuable in densely populated neighborhoods. The greenery contributes to the local microclimate, providing both environmental and aesthetic benefits.
For residents, the garden is made accessible through rectangular box balconies that project from the green wall, allowing them to engage closely with the plants and enjoy the immersive garden atmosphere. The plants grow on a support structure that is securely anchored in the brickwork, receiving water and nutrients through an integrated, precision-controlled irrigation and fertilization system. Maintenance of the plants occurs twice a year, with new additions planted each spring to maintain the garden’s health and visual appeal.
The building itself, privately owned, contains a mix of holiday rentals and residential apartments. Architect Sarah Revière designed the project. (1-6)

Baštalište is an organic community garden initiative located in the town of Slanci, some 20 minutes from the city centre of Belgrade (Ref. 3). It is one of the first initiatives of its kind in Serbia, emerging after organizations such as WWOOF Serbia and the Belgrade Flower Festival, along with activists and citizens, united with the goal of growing vegetables for their own needs. Additionally, they aimed to highlight the numerous neglected and abandoned urban spaces in the city that could be repurposed in this manner (Ref.1). Even though more and more people would like to join Baštalište, the community has been struggling to grow beyond their original plot of 1800 m2, shared between some 30 people of mixed demographics (Ref. 3). They have turned to the municipality to provide more such spaces for urban community gardening but their appeals bear little success (Ref. 2,3). Despite their spatial constraints, the initiative remains open to anyone who would like to visit and help while being financed by membership fees (Ref. 1,2,3). The initiative hopes to eventually scale this type of activity, drawing inspiration from the example of Zagreb, where over 2,000 garden communities were established within 2.5 years after the city decided to repurpose its neglected areas (Ref. 2).

The Mobile Bay National Estuary Program is one of 28 National Estuary Programs established by the United States Environmental Protection Agency, focused on safeguarding and restoring the water quality and ecological health of nationally significant estuaries (Ref 2). One of the four main areas of work of the project (Ref 2) is focused on Ecosystem Restoration and Protection (ERP), aiming at restoring and protecting ecosystem function and services (Ref 4). One of the projects implemented in 2023-2024 in the ERP category is the Deer River Coastal Marsh Stabilization and Restoration project, aiming at restoring and protecting the saltwater marshes of the area (Ref 8).
The issues faced in the Deer River Shoreline are shoreline recession, marsh deterioration, and loss of natural function from erosion, apparently caused by heavy storms, tidal impacts, and wakes from cargo ships entering or exiting the Theodore Ship Channel (Ref 8). Indeed, the saltwater marshes of this area have started to erode at a rapid rate, up to 12 feet per year (Ref 7).
The project aims to enhance the natural function of ecosystem services to improve the area's resilience. It will restore the eroded marsh by creating offshore structures to protect the shoreline and attenuate the waves. The project also aims to restore the water quality of the Deer River by dredging it out, thus improving the water flow. The material dredged out will be used to nourish the marsh (Ref 9).

The Meama Coffee Factory incorporates ecological elements and functionality with architectural design to create a visually striking building. By doing so, the developers respond to requirements set by the city of Tbilisi for a factory that blends into the peri-urban landscape while avoiding the typical industrial appearance. This requirement corresponds to the architect's values of creating a sustainable and durable structure, implemented through multiple measures (Ref. 1,2). Firstly, a 3,680 square meter green roof has been installed, fully covered with local wild grasses and plants (Ref. 1). This green roof serves multiple purposes: it acts as a thermal barrier, reducing the need for additional roof insulation, mitigates noise pollution from the nearby airport and serves as a recreational and meeting area for visitors and employees (Ref. 1,2,3,4). The factory area also features a pine forest to its backside as well as multiple inside atriums covered in greenery (Ref. 2,3).
Lastly, building materials and installation methods have been selected to ensure the durability of the project, such as roofing membranes that withstand root penetration as well as reinforced concrete structures that are waterproofed and protected against corrosion (Ref. 4&5)

The Tbilisi Urban Forest is an ecological restoration project of 5,5 ha spanning two pilot areas initiated in 2020. Located on Mtatsminda ridge around Tbilisi, it is part of a larger reforestation effort within the 700-ha forest territory (Ref. 1,2). The project is funded by the Cartu Foundation and led by the Development and Environment Foundation along with Tbilisi City Hall. Restoration is undertaken to addresses significant challenges such as forest dieback caused by pest infestations, climate change adaptation as well as the creation of recreational infrastructure (Ref. 3,5). Through collaboration among interdisciplinary scientists and urban planners, a novel reforestation strategy has been developed that integrates patches of locally sourced plant communities tailored to diverse soil and slope conditions. This approach incorporates existing trees with new saplings, carefully grafted into existing soil pockets, and focuses on a biodiverse palette of endemic and climate-adapted species (Ref. 1,5). While the project implementation could not be carried out as planned, lacking public participartory due to Covid 19, still 100 jobs were created locally (Ref. 2). Ultimately, the Urban Forest project will enhance ecological connectivity, biodiversity and tourism and also serve the public as an improtant recreational site (Ref. 1,2).
