Collaboration with local community organizations or advocacy groups representing these communities

D-Town Farm, located within Detroit’s River Rouge Park, is a landmark urban agriculture initiative led by the Detroit Black Community Food Security Network (DBCFSN). Since its establishment in 2008, this seven-acre farm—the largest in Detroit—has embodied the organization’s commitment to food sovereignty, justice, and security for the city’s African American community. Each year, the farm cultivates over 30 varieties of fruits, vegetables, and herbs using sustainable and regenerative practices. Key operations include large-scale composting, rainwater retention, solar energy generation, and beekeeping, all of which support its ecological and educational missions.
Beyond production, D-Town Farm serves as a community hub. From May through September, it hosts public events that offer educational and recreational opportunities for children and families. The farm also provides hands-on training for aspiring growers through internships and volunteer programs, fostering community engagement and agricultural skill development. Volunteers play a crucial role in daily operations, with ongoing opportunities available throughout the growing season.
D-Town Farm’s mission extends beyond agriculture, serving as a platform for broader advocacy. By challenging barriers to food access, it addresses food deserts with a focus on empowerment and education. The farm supports the local economy by supplying fresh produce to restaurants, farmers markets, and residents, while its health-focused initiatives, such as the youth-centered Food Warriors Development Program, aim to reduce health disparities within the community.
The DBCFSN’s work at D-Town Farm exemplifies a model of community cooperation and self-determination, promoting equity and justice in the food system. By engaging with both local and broader urban communities, D-Town Farm not only strengthens Detroit’s leadership in urban agriculture but also contributes to food justice movements nationwide.

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).

A small biodiversity park was established in Härlanda Park, an old prison complex which today houses a culture centre, a pre-school and office space. The area was previously used as a small lily garden, but this project implements more biodiversity-promoting features such as a bee hive, varied flowers and trees, different types of soil and insect hotels. The municipal real estate company Higab owns the park and partnered with Stadskupan, which works with urban beekeeping, biodiversity, and rewilding, to design and create the park. They also involved Vägen ut! (translates to "the way out"), a social enterprise that employs people who are far from the labour market due to substance abuse issues to help maintain the park in a socially inclusive way. The park has pedagogic features and events for local businesses and organisations as well as the public. The beehive was established in 2022, while the entire biodiversity park was established in 2023. The project will go on for three years and be evaluated yearly. [Ref. 1, 2, 3].

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.

In 2018, a group of residents from Sector II in the Villa El Salvador district initiated a communal effort to transform an abandoned space into an urban garden (3). This is how Ayllu 21, the first community-based agroecological garden in Villa El Salvador, was born. The project was spearheaded by a group of mostly migrant senior women who decided to dedicate their time and labour to reclaiming a landfill space, to turn it into a productive green area (1). Their philosophy is rooted in the concept of "ayllu," a Quechua word signifying family, collective identity, solidarity, and respect for the environment to foster harmonious coexistence (3).
Today, Ayllu 21 spans 1400 square meters and features 40 plots where agroecological practices are employed (1, 3). The garden aims to become a space for comprehensive development, through promoting environmental awareness, political advocacy, and the fight against gender-based violence in a district that ranks third in the number of violence cases (1).
The vegetables produced are primarily for self-consumption, with any surplus distributed among neighbouring families. If there are any sales, the profits are shared among the members, who work an average of two days per week in the garden (3).
This space seeks to strengthen socialization among women and seniors and foster learning and community-building among neighbours through agriculture. It was initiated with the support of IPES Promotion of Sustainable Development as part of the Sowing in the Desert program (3, 6), and it has received support from a diversity of programmes, such as the framework of the Women United for Food and Environmental Security (MUSA) (1).

Maya’s Farm is a small, CSA (Community Supported Agriculture) sustainable urban farm located in Phoenix, Arizona, where urban development has limited farmland availability. In 2020 alone, Phoenix lost nearly 200 acres of farmland to urban sprawl, putting farms like Maya’s at risk. The farm faced potential closure until the City of Phoenix intervened, providing funding through the Farm Preservation Program, which established the city's first urban agricultural conservation easement. Maya's Farm strives to inspire a local appreciation for sustainable food and to bring renewed value to local food systems.
The farm’s mission is to provide accessible, fresh, locally grown produce to the community while promoting awareness of healthy, sustainable food practices. Through its CSA program, members receive a weekly produce box and have opportunities to come together, honor food traditions, and share stories over locally harvested food. As a CCOF (California Certified Organic Farmers) certified organic farm, Maya’s Farm is committed to organic practices that exclude GMOs, nurture the soil, foster biodiversity, and innovate growing systems. These methods result in healthy soil and cleaner air, contribute to carbon sequestration, and support critical wildlife habitats.
To broaden educational outreach, Maya’s Farm offers several programs that promote sustainable food practices, including its CSA program, an edible classroom series, and a partnership with Arizona State University (ASU). Through this ASU partnership, students gain hands-on experience by participating in daily farm operations.
Building stronger community connections is another cornerstone of Maya's Farm’s work. The farm collaborates with local restaurants, farmers' markets, and community groups to expand its impact. Maya’s Farm, ASU, and Arizona Sustainability Alliance launched an agrivoltaics project with solar-shaded crops. (2, 9, 11, 13, 15)

"The Neighborhood, Environment & Water Research Collaborations for Green Infrastructure (NEW-GI)" project in Warrendale, Detroit, aims to advance green stormwater infrastructure (GSI) knowledge and practice in legacy cities by integrating research on water quality, community well-being, governance, and ecological design. This collaborative effort, involving community members, government entities, and academic researchers, seeks to develop evidence-based strategies for sustainable stormwater management while enhancing urban landscapes and improving residents' quality of life.
In its first phase (2014-2015), the project created bioretention four bioretention gardens, each on two vacant residential properties in the Warrendale neighborhood. in Detroit's Warrendale neighborhood. These sites, constructed by the Detroit Water and Sewerage Department (DWSD) on vacant lots owned by the Detroit Land Bank Authority (DLBA), were monitored for water quality, and resident surveys were conducted to gauge the gardens' impact on neighborhood satisfaction and stormwater management.
The second phase (2016-2019) expanded the scope to refine GSI designs to reduce maintenance needs and further assess their effects on water management and community well-being. It also explored governance structures that impact GSI success, both in Detroit and other legacy cities, contributing to the development of guidance documents for GSI planning and decision-making.
Funded by the Fred A. and Barbara M. Erb Family Foundation, the NEW-GI project represents a transdisciplinary approach to urban ecological challenges, offering valuable insights into how GSI can deliver both environmental and social benefits in cities like Detroit.

The Africatown Connections Blueway project aims to create a recreational water trail by linking 14 culturally and historically significant points along a 10-mile route (Ref 1). Central to this initiative is the preservation of Africatown's rich heritage and natural resources. The project seeks to reconnect residents of Africatown, descendants of the original founders of this self-governing community, which maintained a strong sense of African cultural heritage, to waterways that were historically vital for food, transport, and spiritual practices (Ref 1). By restoring access to these waters, the community can address both environmental and social issues, promoting eco-tourism and business growth while safeguarding cultural heritage (Ref 2). Local leaders emphasize the environment’s role in healing the community and preserving history, highlighting how this initiative can provide economic opportunities and improve quality of life (Ref 2). The project seeks to address the environmental injustices that Africatown communities have endured for decades. The area surrounding Africatown has long been dominated by harmful industries, including aluminium plants and paper mills, which have heavily polluted the water and restricted residents' access to it (Ref 1). With support from the National Park Service and contributions from Mississippi State University, the Blueway transforms neglected river access points into recreational areas, promoting environmental stewardship and cultural awareness (Ref 2).

The Joe Louis Greenway is a 27.5-mile recreational pathway designed to create safe, connected, and equitable spaces throughout Detroit. It will link 23 neighborhoods across Detroit, Hamtramck, Highland Park, and Dearborn, connecting them to each other and to the Detroit riverfront. The greenway will transform a blighted, abandoned rail corridor into a park that runs through the heart of Detroit's communities. (Ref. 2, 3)
This project is guided by a Framework Plan funded by the Ralph C. Wilson, Jr. Foundation and shaped by extensive community input. Residents voiced a strong desire for the greenway to provide off-street recreation and increased access to green spaces across Detroit. Additionally, they advocated for the restoration and remediation of former industrial sites, which the Conrail section of the greenway will address. (Ref. 4) The design incorporates stormwater management to mitigate flooding, native meadow plantings to support bird habitats, and tree-lined paths for shade and improved air quality. The Framework Plan ensures the Joe Louis Greenway will transform infrastructure that once divided neighborhoods into one that unites them, reconnects natural systems, drives economic redevelopment, and fosters a resilient social network. (Ref. 13)
The concept originated in 2007 with the Friends of the Inner Circle Greenway local NGO and became part of the Detroit Greenways Coalition Network Vision in 2009. The Detroit Greenways Coalition Network Vision is a comprehensive plan developed by the Detroit Greenways Coalition (NGO), an organization dedicated to promoting non-motorized transportation and green infrastructure throughout the city. After years of advocacy and collaboration with the city of Detroit, the project’s route was finalized. In 2017, Mayor Mike Duggan announced the greenway would be renamed in honor of Joe Louis, the legendary boxer and Detroit native who championed African Americans' rights and symbolized social justice.

The pilot project in Bairro Padre Cruz, Carnide, Lisbon, is a groundbreaking initiative aimed at enhancing women's safety in public spaces and improving access to public transport. Launched in June 2024, this project stems from extensive consultations with local women to address their specific security concerns (Ref1). It involves strategic interventions like better lighting and the relocation of bus stops to safer areas, ensuring a more secure environment for women (Ref4). A key element of the project is the greening of the area through tree planting and the creation of more harmonised public spaces, contributing to a more pleasant and welcoming neighbourhood (Ref2). Funded by the Recovery and Resilience Plan (RRP), this initiative aims to foster greater inclusivity and safety in urban design, with completion expected by 2025 (Ref4).
