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).

This project, implemented in several schools across Fort-de-France in 2018, focuses on creating arboretums in schools to educate children about Martinique's native natural heritage and raise awareness of biodiversity loss. An arboretum is a curated collection of trees selected for scientific, conservation or public enjoyment.
The initiative, led by the Martinican National Botanical Conservation, is supported technically by the municipal landscaping department and administratively by the city of Fort-de-France and the Martinican School Rectorate. It includes three main activities: a seminar on Martinique's rich yet fragile botanical heritage, an excursion into a forest, and a tree planting event at schools featuring native or endangered plant species. The program has reached at least six schools in and around Fort-de-France.

The Köprüköy Mosque in Adana, commonly named "green mosque", is one of a kind in Türkiye (Ref. 2,5). Its building and minaret are almost entirely covered by poison ivy and appear in vivid green colour from afar. Founded in 1929, it had to be remodelled in the early 60s as it couldn't sufficiently accommodate worshippers in the growing district. The mosque was then entirely built and rebuilt by the community, with its maintenance overseen by the mosque's protection association (Ref. 4). In the 70s, the ivy was planted and has since helped to protect the building from environmental stressors and keep visitors inside the garden and mosque cool during the summer heat (Ref. 4,5,6) Furthermore, the mosque’s well-maintained garden, home to around 280 species, is adored by local, national, and international visitors and tourists, as well as the media (Ref. 1,3,7). Frequent maintenance and rotation of the garden's flowers keep its appearance and function intact, one of which is the profound impact on visitors’ well-being, with many praising the unique atmosphere of the mosque that evokes peace, comfort, and spirituality (Ref. 1,3,4).
During COVID-19, the mosque could only host worshippers during praying hours, after which it quickly continued to bring people back together to garden, rest and socialize throughout the day (Ref. 1).

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)

The Horta Nova Urban Park, located in the Carnide parish (Lisbon), is a recently inaugurated green space that combines horticulture with community recreation. The Carnides neighbourhood is characterised by an inspiring history of overcoming hardship, with residents turning food shortages into opportunities by cultivating community gardens since the 70s. Currently, "the neighbourhood continues to be an example of solidarity, innovation and community spirit" (Ref. 2). In 2013, as a response to food scarcity caused during the post-Troika economic crisis, a group of local residents created an unauthorised vegetable garden overnight, on previously derelict space in the neighbourhood. Only in 2021 did the local authorities officially recognise the vegetable gardens, which since 2013 had operated under an informal agreement (Ref. 3). With the official establishment of the horticultural park, in addition, the park has a newly planted broad lawn, an open-air gym, and a dedicated dog park, creating a versatile space for residents (Ref 3).
Currently, this park features 80 vegetable plots, each with a dimension of 100 m2 per plot, attributed by the municipality through an official application process (Ref. 1). The park is a great reflection of the neighbourhood’s resilience and its history of small-scale citizen-oriented agricultural production that began as a response to social difficulties (Ref 1, 2).

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 D'Olive Creek Restoration project is designed to address the significant environmental challenges facing the D’Olive Creek Watershed and its tributaries (Tiawasee and Joe’s Branch), primarily caused by increased urbanization. Over the last several decades, the area has experienced severe erosion, sedimentation, and habitat degradation due to stormwater runoff from new residential and commercial developments. This runoff has led to stream channel instability, loss of wetlands, and impaired water quality in both D'Olive Creek and Mobile Bay, threatening aquatic and wildlife habitats (Ref 2).
The project involves restoring degraded streams and implementing management measures to reduce the downstream impacts within the watershed. Key activities include stormwater retrofits, stream restorations, and continuous monitoring. These efforts aim to stabilize stream segments and significantly reduce sediment loading into the northeast quadrant of Mobile Bay. This is crucial for improving water quality and clarity, which is necessary for re-establishing submerged aquatic vegetation (SAV) beds that serve as critical nursery areas for shellfish and finfish (Ref 1). By using natural materials like rock and living plants, the project also seeks to create a sustainable and ecologically balanced watershed system (Ref 3).
The anticipated outcomes include enhanced water quality in D'Olive Creek and Mobile Bay, reduced erosion and sedimentation, and the restoration of vital habitats, which will contribute to the region's overall ecological health (Ref 1, 3). This restoration project is part of a broader strategy outlined in the 2002 Comprehensive Conservation Management Plan for the Mobile Bay Estuary (Ref 1).

Fondo Unido Chihuahua, in collaboration with its corporate partners, is committed to raising awareness about environmental care and reforestation. One of its flagship initiatives is the annual tree-planting campaign, "Planting Today to Have Oxygen Tomorrow," organized by United Way Chihuahua in Ciudad Juárez. This environmental initiative focuses on improving the quality of different urban green spaces (parks, school grounds, streets) while fostering ecological awareness in vulnerable communities across the city. The primary objective is to plant a significant number of trees throughout Ciudad Juárez, using native species that are water-efficient and well-adapted to the local climate and soil. In 2022 the initiative aimed to reforest 18 parks located mainly in the south-eastern part of this border city with 1,000 trees. In 2023 and 2024 the intervention focused on planting 850 trees scatted all over the city.

The campaign brings together donations and volunteers through partnerships with various stakeholders, including local and regional governments, private companies, community organizations, and the general public.
United Way Chihuahua oversees the planning, coordination, and logistical efforts for the campaign. On planting days, volunteers gather at designated sites, guided by the organization to ensure successful planting efforts and community engagement (Ref 1-4).
