Increased visibility and opportunity for marginalised groups or indigenous peoples

“The Orchards of the School” is a project led by Antibiotice S.A. through its foundation, "Știință și Suflet" (Science and Soul), which focuses on corporate social responsibility programs. Implemented between 2017 and 2019, employees volunteered to participate in planting orchards in the yards of several schools around the metropolitan area of Iași, including a special education school . The students assisted in planting the orchards and took responsibility for their management afterward.
The primary goal of the project was to instill respect for environmental protection, promote a healthy lifestyle, and cultivate civic spirit within the community among the younger generation. The local authorities prepared the yards for planting, while the Research and Development Station for Fruit Culture in Iași provided standardized methods for proper orchard cultivation.
By 2021 and 2022, the orchards were reported to be thriving and yielding their first fruits for the students (Ref. 1-9).

The Circle Forest project, led by Arboretum Detroit in partnership with Detroit Future City, is transforming a vacant lot the size of a football field in the Poletown East neighborhood into a green space. Once used as a dumping site, the area is being revitalized with 200 native trees, including oak, elderberry, white pine, and juniper. Supported by local groups like Detroit Audubon, Singing Tree, and the US Fish and Wildlife Service, the project aims to improve environmental quality and provide better access to nature for residents. Since 2019, over 120 trees have been planted, with plans to develop a native meadow. This initiative offers a space for recreation and reflection, benefiting the local community, including a nearby nursing home and rehabilitation center. Beyond ecological restoration, Circle Forest fosters connections to indigenous knowledge and respects the wisdom of the original stewards of the land. (Ref.1, 2)

The new 6.5-hectare Anita Berber Park has been created on the site of the former St Thomas cemetery, between Tempelhofer Feld and Hermannstraße. It is named after the dancer Anita Berber, who herself was buried there in 1928. The cemetery was unused and out of use for several years and became accessible to the public through the intervention. (Ref. 3; Ref. 6) The construction period was preceded by a public participation process in which the facilities and design were developed together with the users. The redesign of the space was conducted by a landscape architecture office (Henningsen Landschaftsarchitekten PartG mbB) and financed by the German Federal Government (Ref. 1). The new park, which was planned and financed as a compensatory measure for the construction of the A100 urban highway, increases the quality of local recreation in the densely populated district of Neukölln. (Ref. 2; Ref. 6) An important goal was to achieve high species diversity in the park while preserving its valuable trees and shrubs. The park also offers multiple spots for rest and play as well as a zone for free running dogs. (Ref. 2; Ref. 6)
The park features wooden climbing structures and an old collection of trees with hollows, along with bushes and shrubs. These areas often accumulate rubbish, highlighting the ongoing waste management issues the park has faced since its renovation (Ref. 4).

Lima is grappling with significant challenges driven by climate change, and one of the pressing issues is the shortage of green spaces. According to the PLAM 2035 report, Lima offers only 3.1 square meters of green area per inhabitant, well below the World Health Organization's recommendations (2). Moreover, food insecurity is on the rise, with Peru leading the region in this crisis (4). Compounding these issues is the lack of coordination among state actors tasked with addressing the country's food crisis (2).
In response to these challenges, the Energy Network of Peru (ISA REP) has been running the "Huertos en Línea" project since 2004 in the districts of Villa María del Triunfo and San Juan de Miraflores as part of its corporate social responsibility initiatives (2, 3, 6). This project aims to establish community gardens that promote environmental awareness, reduce pollution in these affected areas (1, 2), provide food for vulnerable populations, and create income-generating opportunities through the sale of surplus produce (1, 6). The gardens are strategically located in power grid easement strips, which are often plagued by encroachment, burning, and waste accumulation—issues exacerbated by poverty, extreme poverty, and weak social organization in these areas (5, 6).
Originally planned with an annual development and growth strategy up to 2011, the project has been extended year by year and has now been active for nearly two decades. Beneficiaries continue to receive technical and material support, and the number of community gardens has grown. In 2019, the initiative expanded to include two bio-gardens in the Trujillo districts of La Esperanza and El Porvenir (7, 9). The project has contributed to improving soil quality, recycling and transforming waste, enhancing landscape aesthetics, reducing burning and waste accumulation, and implementing drip irrigation systems.

Spaces of Opportunity is an initiative created by several organizations in Phoenix, that aims to bring food security and sustainability to the south Phoenix community. The initiative aims to reach its goals through its community garden that incorporates 19 acres of barren land (dessert) that can be used by locals for growing food and earning an income while providing the community organically grown produce. The mission is to enable all South Phoenix families to have affordable access to healthy food, active living and healthy roots of their cultures (1, 2, 4, 6, 8).
The initiative started in 2011 when several local actors formed a coalition with a shared vision of improving well-being by addressing the natural, built, and social environments. Spaces of Opportunity is the only local food system of its kind in the Phoenix metropolitan area, and unique in the country for the diverse strengths of the committed partner organizations and their shared vision to bring food security, build sustainability, and cultivate community.

This project aimed to create an urban forest that will grow within Dublin’s Darndale Park, which is popular among students and sports clubs. The objective is to offer the community a green area where they can gather, appreciate nature, and enhance their knowledge about it. The new forest will act as a windbreak for the nearby fishing pond and aims to address challenges related to heatwaves that endanger the lives of young and elderly people. To foster a sense of inclusion and unity, the forest is designed in a doughnut shape, consisting of 3,000 native species like oaks, birch, willow, and hazel, with the trees forming the outer ring (1, 2). This urban forestation initiative is a component of the Uforest project, which is funded by the European Commission and supported by Etifor (environmental consulting company established within the Department of Land, Environment, Agriculture and Forestry of the University of Padua) and Ersaf (an instrumental body of the Lombardy Region) . The Uforest project seeks to enhance Europe's innovation capacity by fostering collaboration among universities, cities, and businesses to develop a novel approach to urban forestry (1).

The himmelbeet is an intercultural, inclusive community garden in Berlin that has been inviting people to garden and harvest their own produce since 2013. The garden offers around 200 raised beds that are communal and can be rented by neighbors, individuals and institutions (Ref. 1; Ref. 3). The project aims to familiarize children and adults with ecology, sustainability and healthy eating and to offer space for social exchange and education, while being inclusive to people with different (dis)abilities and backgrounds (Ref. 2; Ref. 6). The design and implementation of environmental education workshops are a vital part of the work. (Ref. 1; Ref. 6) With its own café and vegetable production, himmelbeet is strongly oriented towards the principles of the economy for the common good. The garden team also looks after other gardens in the city - on behalf of educational institutions, social institutions, housing associations and neighborhoods. (Ref. 1; Ref. 6)
Originally located in Ruheplatzstrasse, the garden moved in 2021 to Gartenstrasse, because of land disputes with the providing land owners and the demand of the space for other social projects. (Ref. 8; Ref. 11)

Trénelle-Citron, located north of downtown Fort-de-France and separated by the city bypass, La Rocade, was originally established in the 1940s by Black Martinicans migrating from rural areas. Today, the neighborhood faces significant economic and social challenges. In 2016, young residents from the neighborhood alongside a local NGO launched a grassroots initiative to improve their community. They transformed a former municipal quarry, which had deteriorated into an informal dump, into a thriving shared urban garden, benefiting the local population. This project, based on traditional ecological gardening techniques and the cultivation of native crops, aimed to revitalize Trénelle-Citron—a densely populated area grappling with social exclusion, a shortage of green spaces, and limited economic opportunities for its youth (Ref 2).

The garden, developed on municipal land with guidance from the Ypiranga Martinique NGO, support from the local school, and collaboration from various stakeholders, now plays a vital role in the area. It raises awareness about agroecology, offers socioeconomic opportunities, promotes healthier lifestyles, and fosters social connections among residents. Spanning approximately 1,000 m², the site includes an office, a covered area, tool storage containers, market garden plots, a composting area, and a chicken coop managed by a local resident (Ref 7). In Martinique, such shared urban gardens are increasingly seen as important tools for sustainable development (Ref 5).

Detroit’s neighborhoods grapple with a dual challenge: neglect and flooding. When the city stopped maintaining alleys in the late 1980s, responsibility shifted to residents. However, with limited resources and a declining population, many of these alleys fell into disrepair, becoming symbols of urban decay. This neglect is further compounded by the increasing frequency and intensity of severe storms, which have exposed the city's vulnerabilities in stormwater management, leading to regular flooding.

To address these challenges, the "Alley Activation" project, launched in 2020 by a team of researchers at the UM-Dearborn in partnership with local residents and organizations, seeks to transform neglected alleys into vibrant greenways, rain gardens, and pollinator habitats. The project focuses on cleaning and greening alleys located in 2 neighborhoods namely Littlefield and McNichols. The activated alleys are bounded by Littlefield, Hartwell, McNichols and Outer Drive roads. These roads enclose an area of 141,436 square meters, located in the Bethune community and the Hubbell Puritan neighborhoods. Alley Activation involves clearing blocked alleyways and turning them into inviting, productive spaces that support sustainability goals. These revitalized alleys serve as a "green capillary system," contributing to the city's environmental, cultural, and social well-being. As these spaces are cleared, they offer a fresh opportunity to re-imagine their role and potential within the community. (1,2,3,4,5)
