Achieved restoration of derelict areas

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).

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)

The Jardim do Caracol da Penha project transformed a vacant urban area into a community garden and recreational space in Lisbon. Initially planned as a parking lot, the project was reimagined by local residents, led by Rita Vieira Cruz, and submitted to the Participatory Budget in 2016, garnering over 9,000 votes (Ref 2). The one-hectare garden connects the Arroios and Penha de França parishes and features leisure areas, an amphitheatre, playgrounds, and a community garden (Ref 4). Its design was shaped by citizen input, emphasizing sustainability and accessibility, with plans to support activities such as outdoor cinema and community gatherings (Ref 2).

The Oxygen Alley project, developed by the NGO Arboretum Detroit, is a green space located in the Poletown East neighborhood of Detroit. Spanning four formerly abandoned lots, the project, completed in 2023, serves as a significant environmental and community initiative aimed at improving local resilience and promoting environmental justice. Named in recognition of the closure of the Detroit waste incinerator—a major source of pollution for over 30 years—the project replaces a long-abused landscape with a thriving greenway that enhances both the ecological health and social well-being of the area.
Key features of Oxygen Alley include the planting of air-filtering trees and the creation of a shaded greenway lined with wildflowers, benches, and walking paths. This new green space not only provides a recreational area for residents but also functions as a natural air conditioner, stormwater sponge, and wildlife habitat. It addresses the neighborhood’s lack of tree cover, offering shade and cleaner air while helping mitigate the effects of climate change.
The project also underscores the neighborhood's longstanding struggle for environmental justice. The removal of 400 feet of asphalt and the remediation of a polluted landscape highlight the community’s efforts to reclaim and revitalize their environment. Oxygen Alley serves as both a functional green space and a monument to the residents’ victories over the waste industry, symbolizing their continued fight for clean air and livable spaces.
Supported by grants from the City of Detroit, Michigan Department of Natural Resources, and DTE Energy Foundation, among others, the project was brought to life through over 300 hours of volunteer labor. The creation of this greenway not only improves the neighborhood’s walkability but also offers a vision for a more sustainable and equitable future, serving as a model for urban revitalization projects across Detroit and beyond.

The Praderas de Vida garden is an initiative to transform a former rubbish dump into a source of employment and empowerment for the residents of the Praderas de San Juan de Miraflores Human Settlement (1). This agroecological community garden was developed as part of ISA REP's Sustainable Easements programme (13), located in the easement area of Peru's energy network, and it has collaboration efforts with KUNAN, Misha Rastrera, and La Muyita, brings together twelve female heads of households who cultivate, harvest, and process a variety of medicinal plants that have aromatic, antiseptic, and relaxing properties (2, 3).
Beyond agricultural production, the garden has become a hub for emotional and economic support, fostering a connection with nature through plant care and interaction with the local ecosystem (3). It has also led to the establishment of a social enterprise, "Praderas de Vida," allowing women to participate in agroecological fairs to market the products derived from the medicinal plants grown in the garden (3).
The garden has evolved into a space for learning and community collaboration, promoting the importance of sustainability and biodiversity conservation (6).

Earthworks Urban Farm, located on Detroit's east side, is a pioneering initiative of the Capuchin Soup Kitchen that integrates sustainable agriculture, social justice, and community development. The Capuchin Soup Kitchen is a religiously affiliated soup kitchen and non-profit organization located in Detroit, Michigan. It was founded by the Capuchin friars to provide food for the poor during the Great Depression and is sponsored by the Capuchin Franciscan Province of St. Joseph. The farm was founded in 1998 by Brother Rick Samyn, and began as a small garden focused on educating local youth about healthy food and its origins. Over time, this modest garden expanded into a 2.5-acre urban farm, including 1.5 certified organic acres—making it Detroit's only certified organic farm.
The farm’s growth included adding a large plot behind its partner, Gleaners Community Food Bank, as well as establishing an apiary with up to 40 hives, a greenhouse for transplant production, a hoop house for year-round crops, and a community orchard. Earthworks' work has evolved along with its physical space, significantly extending its reach.
A wide variety of vegetables are cultivated here without herbicides or pesticides, with harvests distributed to local residents and included in meals at the Capuchin Soup Kitchen, ensuring fresh, nutritious food for those in need. Beyond agriculture, Earthworks serves as a community hub, engaging volunteers, offering educational tours, and supporting thousands of community gardens across Detroit with transplants and expertise.
Committed to evolving its programs, Earthworks has experimented with mobile markets, community-supported agriculture (CSA), and local market stands, demonstrating its dedication to meeting community needs through sustainable practices.

The Avas Tomato Community Garden, located in a formerly neglected area of the Avas hill of Miskolc, has transformed from an overgrown, rat-infested, and litter-strewn space into a thriving community garden. Just a few years ago, this site was a source of concern for local residents, plagued by issues such as homelessness and illegal dumping. Today, however, it stands as a flourishing green space with fresh garden beds, composting boxes, a pavilion offering shade to gardeners, and a renewed sense of community spirit.
The seeds of the Avas Tomato Community Garden project were planted in the fall of 2014, led by Zsolt Jakab and Ákos Káli-Nagy. The initiative began with the establishment of the "Panelkertész" club, and by 2016, with the support of a local representative, the garden began to take shape. The gardening community that blossomed in the spring of 2017 was built upon the strong relationships within the established Avas neighborhood. Working together, members constructed the garden beds according to a precise schedule and, through frequent discussions, developed a close-knit community. The garden now consists of 20 large and 6 smaller beds, with 18 families actively growing vegetables, herbs, and spices, alongside raspberry and strawberry plants by the fence.
The community has greatly benefited from both the professional support and supply donations provided by the Miskolc Ecological Institute Foundation. Additionally, the Dialóg Association has played a key role in organizing the garden users and fostering collaboration. Initially, Dialóg appointed a coordinator for the garden, but this responsibility has since been handed over to the gardeners themselves. Owned by the Municipality of Miskolc, the Avas Tomato Community Garden continues to thrive as a model of successful urban gardening, uniting people with a shared passion for gardening and a commitment to building a strong, supportive community.

The first medicinal plant library in Martinique was created by the Ypiranga Martinique association, which inaugurated the project in 2019. The initiative was developed to preserve and revitalize traditional knowledge of medicinal plants in Martinique, integrating agroecology , modern scientific understanding, and ancestral practices.
The project is located on land provided by the municipality in the Tivoli neighborhood, and it serves as an educational resource, a functional pharmacy, and includes a small shared vegetables garden. Visitors, local residents, and researchers can access information on over 150 native Caribbean plants and their medicinal properties. The site includes two educational trails: one following the river that crosses the garden and a sensory trail designed to help visitors "reconnect with nature." Each plant is identified with information boards detailing its medicinal uses, including whether these uses are scientifically validated.
The project also aims to address social exclusion by offering reintegration workshops to troubled teenagers and the unemployed.
The project was financed through a combination of sources: an EU-funded call for projects, a crowdfunding campaign, and regional and national public subsidies.
As a result of its success, in 2021 the initiative was formally replicated with the support of the Caribbean Interreg "OSAIN" project, which led to the creation of 14 additional plant libraries in schools and public spaces. Volunteers and community-based efforts continue to sustain the project, and it has become a model for similar initiatives. (Ref. 1,2,4,5,6,7)

The "Recuperación del Laguito" project aims to restore El Laguito, a coastal water body in Cartagena, Colombia, severely affected by sedimentation that blocks natural water exchange with the Caribbean Sea. This blockage has led to stagnant, low-oxygen water, degrading water quality and aquatic ecosystems (ref 1). The project seeks to restore El Laguito’s environmental and social functions by reestablishing seawater flow, reducing sediment impact, improving water quality, and reviving the ecosystem. Additionally, it aims to provide data to guide long-term solutions for sustainably managing this community resource (ref 1).
The project is a response to recurring ecological crises, such as frequent fish die-offs due to low oxygen levels. Local residents initially took matters into their own hands, manually attempting to reopen the channel. The formal intervention started following a 2019 directive from the Ministry of Environment and Sustainable Development, outlining a phased strategy: short-term installation of an axial pump for water exchange, medium-term studies for a permanent fix, and long-term construction plans (ref 3). Currently, the project involves using heavy machinery to clear sediment and allow seawater inflow, supported by the Gobernación de Bolívar, Cardique, and the Cartagena Mayor's Office. This phase serves as a transitional step towards a more sustainable, permanent solution (ref 2). The project’s impacts focus on ecological restoration. Short-term benefits include better oxygenation, reduced harmful algal blooms, and revived marine life. Long-term goals encompass sustainable water management, ecosystem stabilization, tourism enhancement, and the development of recreational and sports facilities in harmony with environmental conservation (ref 4).

Over the past two decades, as Phoenix’s population has surged since the 1990s, large expanses of farmland have been paved over to make way for urban development. This transformation has increasingly disconnected the city from its agricultural roots. In 2000, Janna Anderson recognized a growing need for local farms to strengthen their ties with the community and for increased access to fresh, locally sourced produce. With a vision to reconnect the community with its agricultural heritage, she purchased a historic orchard property in southern Phoenix, near South Mountain, in 2011. The property, which included a 1918 adobe home, was transformed into a thriving mixed-fruit orchard.
At Pinnacle Farms, Janna planted over 1,200 trees, including peaches, apricots, and rare Maktoom Dates, which were brought to the U.S. from Iraq in 1910. These heritage crops have unique flavors and textures not commonly found in grocery stores. In 2015, the farm became certified organic, underscoring Janna’s commitment to sustainable farming practices. Her focus is on cultivating varieties that are uniquely suited to the arid Southwest climate, using methods that conserve water and promote soil health.
Janna’s approach to farming also highlights the potential of heritage varieties to support food security in the desert. By growing these rare and resilient crops, she not only preserves biodiversity but also brings attention to how such practices can contribute to a more sustainable, local food system. Pinnacle Farms serves as a living reminder of Phoenix’s agricultural history, a place where fertile soil and sustainable farming practices continue to thrive. The farm embodies the deep agricultural roots of the region, connecting Phoenix’s past to its future and proving that the city’s rich farming tradition is far from lost. (1, 2, 6, 8)
