Giulia's Farm is the first project launched by the Italian NGO Terre Colte in Sardinia, focused on transforming unused agricultural plots into a productive community garden. Initiated in 2014, the project covers approximately 3,000 square meters (out of 18,000 sqm owned by the NGO). The garden leases 50-square-meter plots to local residents, known as "ortisti," who cultivate the land using organic and natural farming methods. This approach not only revitalizes neglected land but also strengthens community bonds and promotes sustainable agriculture (Refs. 1 & 2).
The project operates on a cooperative model, ensuring that the land remains accessible and productive while fostering a connection between people and the environment. Participants share resources and knowledge, creating a network of mutual support that enhances both social and environmental resilience.
Beyond its agricultural impact, Giulia's Farm aims to preserve Sardinia's agricultural heritage and combat land speculation. By involving the community in farming, the initiative helps protect these plots from being sold for non-agricultural purposes, ensuring they remain dedicated to food production. The project also demonstrates the potential for reclaiming abandoned land, fostering local food production, and building a more sustainable and resilient food system.
Giulia's Farm has gained attention as a replicable model for other regions facing similar challenges of land abandonment and environmental degradation (Refs. 2, 3 & 4).

The Ciénaga de la Virgen is a coastal wetland (cienaga) located on the north side of the border of the city of Cartagena, separated from the sea by La Boquilla's sandy beach. It has a maximum width of 4.5 km, a length of approximately 7 km, a water body area of about 22.5 km², and depths of up to 1.6 m. It is connected to the city's canal system (ref 1). The recovery project of la Cienaga de la Virgen, led by EPA Cartagena, is proposed as a strategy to address the issues affecting the water body, local communities, the economic activities that depend on it, and the ecosystems that regulate the water cycle and provide multiple services, many of them essential, with an integrated and global management approach based on the basin as the unit for planning and resource management (ref 14). Some of the main problems of the wetland are related to illegal settlements on its shore, as well as illicit dumping of waste, pollution by wastewater from the illegal settlements and deforestation of mangroves (ref 4). Key activities include stopping illegal occupation by relocating established families, improving roads, promoting reforestation, encouraging social participation, managing wastewater, and enhancing tidal systems (ref. 1 and 15).
Alonside the EPA, other stakeholders involved include the regional authority "Regional Autonomous Corporation of the Canal del Dique" (Cardique), with jurisdiction in the rural area, and Cartagena Mayor's Office, and the local community, involved in all the stages of the plan thanks to the “mesas de governance” or "governance tables", discussion spaces where different actors participate in the decision-making (ref 2).

“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 mangrove area of Morne Cabri, located in the municipality of Le Lamentin and sharing the bay of Fort-deFrance, is the largest mangrove area in Martinique. Since 2011, the municipality has led efforts to understand and better manage the area (Ref 1). The natural regeneration of the mangrove is threatened by fresh water run-off (from waste and rainwater), invasive species and pollution. However, it is an important protection against extreme weather events, operates as a carbon sink for the island and provides recreational activities (Ref 1). The municipality has led several initiatives supported by volunteers, local businesses, national subsidies and private donations (See: Ref 2, 3, 4, 11).

The NatureRx Rain Garden Pilot is a community-driven initiative aimed at addressing urban runoff and its associated challenges, implemented by Bí URBAN, a community hub and social enterprise in Dublin focused on urban regeneration. The pilot project developed in Stoneybatter, Dublin involves diverting rainwater from residential rooftops into specially designed rain gardens (1). The area is used as the first trial area by installing around 100 rain gardens (3, 11). Built to fit neatly into available spaces, these self-sustaining planters will filter rainwater through the garden, with overflow pipes in place to prevent flooding during heavy downpours (1).
It is expected that these gardens will transform sterile urban spaces into green areas, enhancing biodiversity, providing habitats for pollinators, and acting as carbon sinks (1,3).

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.

The Productive Backyards Program is led by the NGO Granitos de Paz with the goal of promoting food security and income generation for vulnerable families in Cartagena. The program supports the creation of green gardens in household yards, provide technical training in planting, plant care, and supplies, as well as guidance and support for the creation of productive gardens, it also supports the commercialization of crops, fostering social cohesion within homes and positively impacting their environmental surroundings, nutrition, and health (ref 2, 3). A productive backyard is a small plot of land dedicated to growing vegetables for the family's daily consumption, providing fresh, healthy, and nutritious food. Family labour is utilised, offering both economic and nutritional benefits. This activity helps reduce malnutrition, improve the environment, and enable the commercialisation of organic products by making use of household yards (ref 6).
The program is led by the NGO and occasionally receives support from the mayor's office. The mayor's office has provided kits to the families with gardening tools, a watering can, mesh for enclosures, and seeds for 12 species, including tomatoes, sweet peppers, eggplants, bell peppers, Swiss chard, cabbage, and other vegetables. In addition to these supplies, families received training in entrepreneurship and business ideas for marketing their products, self-consumption, and all related concepts aimed at increasing production (ref 1 and 2). Currently, the program counts with 450 backyards in different neighbourhoods of Cartagena (ref 1).

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 project consists in creating an urban orchard at a juvenile detention center. Strickland Youth Center welcomes troubled youth with the final aim of the intervention is to ensure a successful reintegration of youth into the community (Ref 4). The orchard is aimed to be maintained by the youth of the center, providing them with skills and preparing them for the job market (Ref 2). The orchard harvests will provide healthy food options for low-income and minority residents (Ref 1) in the surrounding neighbourhood that has been identified as a food desert (lack of nutritional options available) (Ref 2). The project also has an educational purpose on healthy food for the youth and residents (Ref 3). Besides, the orchard's green space aims to contribute to beautification (Ref 1) and to sequester carbon dioxide (Ref 1).
