Villa Mosha community garden
According to the FAO, in 2022, 16.6 million Peruvians faced moderate or severe food insecurity, representing an increase of 1.5 million compared to the previous year (3). This situation was exacerbated by the health crisis, inflation, and job losses, leaving three out of ten Peruvians in poverty in 2021. The situation was particularly critical in Metropolitan Lima and Callao, with 14% of families reporting difficulties in acquiring protein-rich foods due to their precarious economic situation (2).
In response to this food crisis, the Municipality of Lima implemented the "Lima te Cuida" (Lima Takes Care of You) initiative, in which residents from vulnerable areas got training to create urban gardens and produce organic compost to help the community kitchens in these areas become self-sustainable (1, 2). An example of this initiative is the community garden in A.H. Villa Mosha in San Juan de Lurigancho, where a community garden has been built, and community members have been trained in small-scale planting, cultivation, care, and harvesting of various foods (2).
This initiative has been supported by the MUSA project "Mujeres Unidas por la Seguridad Alimentaria y Ambiental" (Women United for Food and Environmental Security) as part of the project "Alimentando a Lima desde Adentro" (ALDA) (Feeding Lima from within), which has had an impact in eight districts of Lima to strengthen food security (3). In addition to promoting urban agriculture, the project seeks to influence public policy through training and development of proposals to promote urban agriculture at the local level (4).

GLAS Garden in Ballymun
The GLAS Garden in Ballymun was established in 2011 by the NGO Global Action Plan, serving as a community-driven initiative that offers a welcoming and accessible space where people of all ages and abilities can engage with nature, learn new skills, and build connections within their community. The garden is actively utilized on a weekly basis by various groups, including St. Michael’s House, Saol Clubhouse, the Central Remedial Clinic, Ballark Youth Training, and Young Ballymun. It features a polytunnel for year-round growing, a whimsical fairy garden, and numerous microhabitats, including a pond, composting systems, a grow dome, and an innovative rainwater harvesting system made from recycled plastic bottles.
As part of the social regeneration program for Ballymun, the Green Living and Sustainability (GLAS) community garden has been operated by Global Action Plan (GAP) since its inception. It is supported by Dublin City Council under the Social Regeneration Fund and serves as a hub for environmental education and social inclusion in the area.
GAP’s GLAS garden brings together individuals of all ages and abilities, providing a socially inclusive space for participatory learning and active exploration of sustainability. It plays a crucial role in helping individuals and groups reduce their carbon footprint, produce organic food, and enjoy nature, thus transforming the garden into a space for positive change. (1-5)

Floating University
The Floating University was initiated in 2018 at the rainwater retention basin of the former Tempelhof airport in Berlin. Though not an official university, it serves as a space for transdisciplinary, communal learning, transforming an abandoned urban site into a vibrant community resource. The project reclaims the basin, hosting workshops and events that range from ecological lectures to cultural and art programs, fostering collaboration between diverse disciplines and communities.
The architecture collective raumlaborberlin originally envisioned the project as a six-month initiative. Artists, universities, and seminar groups contributed to designing the space and organizing workshops. However, due to its success, an NGO, Floating e.V., was established to sustain the project. Today, the NGO manages the site and continues its mission of engaging communities with urban and ecological themes.
After Tempelhof airport closed in 2008, the basin was infrequently cleaned, leading to contamination and sediment accumulation. Over time, a wetland ecosystem emerged, attracting plants, insects, birds, mammals, and amphibians. This natural development complements the Floating University’s infrastructure, which consists of open timber structures like a kitchen, art installations, communal spaces, vertical gardens, gardening beds, and an auditorium. These structures integrate seamlessly with the basin’s existing technical framework and wetland environment.
Floating e.V. aims to make the basin accessible to Berlin’s urban population while sparking discussions about urban climate, resource management, and water cycles through diverse and artistic programs. Smaller initiatives focus on specific ecological themes, such as plant diversity and soil health, through projects like a seed archive and soil lab.
The Floating University exemplifies how abandoned urban spaces can be revitalized into hubs for learning, creativity, and ecological awareness. (1-3, 8, 9)

Green Corridor "Lazaro Cardenas" in New Belgrade
Named after the former Mexican president Lázaro Cárdenas, this green corridor project stretches over 4,5 km throughout one of the most densely populated areas in Belgrade. It was first built in the 1970s, connecting the building blocks 45, 44 and 70 of Novi Beograd, but has deteriorated since then (Ref. 4,9). Given the fact that close to 40.000 people live in the area which its highly vulnerable to climate change, action was taken to fully reconstruct the corridor for the benefit of local and surrounding residents (Ref. 3,4).
The project was implemented in three phases, according to the three blocks adjacent to the construction site starting in 2019. During the third implementation phase in 2022, however, major delays occurred due to disagreements with the local neighbourhood association "Common Action Block 70 and 70a", which demanded to be taken into consideration in the project's design (Ref. 2,5). Despite some cooperation between the responsible authority (Greenery Belgrade) and the association, demands could not be met (Ref. 5). In the end, the project was carried out as originally planned by the authorities, with a delay of approximately one year. Ultimately, the green corridor provides ample amenities for sports (bicycle lanes, basketball courts, playgrounds, etc.) and recreational activities (benches, chess area) as well as low-barrier infrastructure for all age groups (Ref. 9).
The project was initiated by President Aleksandar Vučić and supported by the current mayor of Belgrade, Šapić, who both have roots in the district (Ref. 4,6).

GLAS Community Garden in Blanchardstown
A community garden opened in 2023 on the Technological University (TU) Dublin Blanchardstown campus. This environmental education and social inclusion project is a collaborative effort involving Fingal County Council, Global Action Plan Ireland, TU Dublin, and the local community. It provides a space for local groups and schools to grow fresh produce, reconnect with nature, and foster a stronger sense of community.
Rooted in a successful template developed by Global Action Plan in Ballymun, this initiative promotes social and cultural inclusion alongside environmental education. The Green Living & Sustainability Community Garden (GLAS) aims to create an inclusive environment that welcomes individuals of all ages, abilities, and backgrounds. More than a site for cultivating plants, flowers, and vegetables, the garden serves as a hub for fostering social connections, enhancing well-being, and offering valuable educational opportunities.
The garden provides individuals with the chance to engage in social horticulture, exploring the connections between food, health, biodiversity, and global issues such as climate change. It operates on organic and regenerative principles, with all tasks and harvests shared by volunteers. Additionally, the garden will support youth gardening projects and public workshops on topics such as growing food, composting, water harvesting, and waste management. Beyond its environmental benefits, the garden helps people connect with one another, positively impacting social, physical, and mental well-being.

River corridor restoration: Love Your River Stour
Sourced from Northern Worcestershire, the River Stour has played a significant role in the industrial heritage of Birmingham and the Black Country (Ref 1). It consists of 11 Water Framework Directive water bodies and multiple tributaries, spanning 200 km in length (Ref 2, 3). Once a pristine Salmonid river that powered the Industrial Revolution, rapid industrialization severely impacted the river, leaving it heavily polluted with sewage (ibid.).
Initiated by the Birmingham and Black Country Wildlife Trust (BBCWT) in 2021, the Love Your River Stour (LYRS) project focuses on Dudley and Wolverhampton, aiming to transform the River Stour and its surrounding green spaces into a beautiful, wildlife-rich source of pride for local communities and to create a corridor for wildlife to thrive through the heart of the Black Country (Ref 4).
Phase 1 of the project was completed in June 2023, bringing significant improvements along the river (Ref 5, 6, 7, 8). In Phase 2, the project will extend to a stretch running through Cradley Heath and Lye (Ref 7, 8). This initiative is funded by the UK Government's Green Recovery Challenge Fund.

Recovery plan of the Juan Angola Channel
The Juan Angola River is an urban channel included in the system of rivers and channels of Cartagena, and it connects the Ciénaga de la Virgen wetland and the Bay of Cartagena, facing similar issues as the Cienaga de la Virgen such as illegal occupation of its shores, illegal waste dumping, deforestation of mangroves, and pollution. The recovery plan for the Juan Angola River is led by the EPA Cartagena (Environmental Protection Agency), with the support of other institutions, aiming to restore the Juan Angola’s ecosystem. This includes targeting the mangrove forest, dredging the natural channel, and delineating buffer zones with urban infrastructure to create public recreational spaces. The activities involve relocating people illegalling cupping informal settlements from the river shore, moving an existing bridge (the Benjamín Herrera bridge) which obstructs the current, recovering the low tide and riverbed areas, building pedestrian paths, clean the riverbank, recover mangrove areas and establish programs of education and environmental awareness (ref 1 and 2).
Tres Rios, Arizona Ecosystem Restoration Project
The Tres Rios Ecosystem Restoration Project is an ambitious initiative aimed at revitalizing a seven-mile stretch of the Salt and Gila Rivers in Phoenix, Arizona. The Tres Rios Environmental Restoration project involves the rehabilitation of nearly 700 acres in and around the Salt River, restoring a vital wetland and riparian habitat. Initially conceived in 1993 to tackle water quality issues and improve flood control, the project gained significant traction in the 2000s through a partnership between the City of Phoenix and the U.S. Army Corps of Engineers (USACE). Funding was structured with 65 percent from the USACE and 35 percent from the City of Phoenix and the Sub-Regional Operating Group Members, including Scottsdale, Tempe, Glendale, and Mesa.
The Tres Rios project encompasses habitat restoration, flood control, and recreational development, with the primary objectives being to restore a degraded ecosystem, enhance water quality, and provide new recreational spaces. Construction involved relocating 1.6 million cubic yards of earth to shape three large wetland zones and two deep-water retention basins. Additionally, 18,000 feet of underground water lines and 600 feet of 84-inch fiberglass effluent pipelines were installed. To establish a thriving wetland habitat, the project coordinated the planting of over 300,000 aquatic and terrestrial plants.
Habitat restoration efforts re-establish native vegetation and create wetland areas that support local biodiversity. The lush and scenic Tres Rios is now home to more than 150 different species of birds and animals like muskrats, raccoons, skunks, coyotes, bobcats, and beavers. By using treated wastewater to sustain the ecosystem, the project reduces dependency on natural water sources, thereby helping to mitigate water scarcity. The Tres Rios Ecosystem Restoration Project serves as a model for sustainable urban ecological initiatives, combining environmental health with community benefits. (1-8, 10-13)

Gardens in schools project
The "Gardens in Schools" project (September 2021 to December 2022) aimed to establish gardens in 15 schools across four municipalities within the Communauté d'Agglomération du Centre de la Martinique (CACEM), including Fort-de-France. The goal was to provide educational and technical resources for teachers to conduct workshops on sustainable development, pollution, and agroecology. The project encouraged schools to maintain these gardens autonomously as long-term educational tools. Students were involved in greening their schools and growing their own fruits and vegetables, while teachers received three training sessions and ongoing support through the community-based "Koudmen" tradition (Ref 1; 3). The project also involved distributing 45 gardening kits to schools across the island.( 1; 2; 3).
The project was led by the Ypiranga da Pastinha Popular Cultural Center (CCYPM) in collaboration with the STE2D academic mission on sustainable development education (a joint effort of the Martinican School Rectorate and CACEM). Financial support came from the Ministry for Food, Agriculture, and the Forest (DAAF) and CACEM (Ref 1; 3).
The project was designed to promote sustainable development education, enable self-sustaining school gardens, and raise awareness about pollution and agroecology among students and teachers.
The project supported the municipal strategy to develop urban gardens and aimed to integrate environmental education into school curriculums and it aligned with the urban gardening strategy "Jaden l’anmou," which included the municipality of Fort-de-France (Ref 1; 2; 3). (Ref 1; 2; 3)

Independencia's Green Belt
The Cinturón Verde de Independencia initiative is a pilot intervention that seeks to plant an urban forest in the lower middle-class district of Independencia (1) in the northern part of the urban territory (3). Here, 19% of the population lives in high-risk conditions, settled on steep slopes, and threatened by landslides (3).
It is part of a broader planning strategy that involves proposals engaging different levels of government (4). This project seeks to afforest the district's hillsides to improve the environment, reduce air pollution, improve the quality of life of its inhabitants, manage waste, regulate shade, control erosion, increase wild biodiversity, and provide spaces for environmental education (2). The Independence Green Belt is linked to a wide range of plans, projects, and decrees that have been developed by actors at different levels of government since 2016 (4). It works hand in hand with the EBA Lomas programme and seeks to create a green belt along the Lomas-city interface, which acts as a buffer zone for this sensitive ecosystem and creates a protective boundary against the expansion of irregular human settlements while providing a space for environmental awareness (2).
This program was developed by a consortium of multiple private, public, national, and international parties with strong community support (3). In two phases, an urban forest park of 4,800 of native trees irrigated with treated wastewater has been planted. During the first phase, PREDES planted 3,300 trees with USAID support in 2015, and another 1,500 were recently planted by PERIFERIA (consultants) (3).
The Independencia Green Belt occupies the hill areas of the district of the same name and relates to a possible metropolitan-scale buffer belt.
Its boundaries take advantage of the seven Sustainable Ecotourism Forest Parks (PFES) in the District Municipality of Independencia (MDI), as well as 115 hectares of the Amancaes Lomas (4). It aims to conserve 400 hectares (4).
