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).

Recovery project for La Cienaga de la Virgen
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).

In-Line Gardens
Lima is grappling with significant challenges driven by climate change, and one of the pressing issues is the shortage of green spaces. According to the PLAM 2035 report, Lima offers only 3.1 square meters of green area per inhabitant, well below the World Health Organization's recommendations (2). Moreover, food insecurity is on the rise, with Peru leading the region in this crisis (4). Compounding these issues is the lack of coordination among state actors tasked with addressing the country's food crisis (2).
In response to these challenges, the Energy Network of Peru (ISA REP) has been running the "Huertos en Línea" project since 2004 in the districts of Villa María del Triunfo and San Juan de Miraflores as part of its corporate social responsibility initiatives (2, 3, 6). This project aims to establish community gardens that promote environmental awareness, reduce pollution in these affected areas (1, 2), provide food for vulnerable populations, and create income-generating opportunities through the sale of surplus produce (1, 6). The gardens are strategically located in power grid easement strips, which are often plagued by encroachment, burning, and waste accumulation—issues exacerbated by poverty, extreme poverty, and weak social organization in these areas (5, 6).
Originally planned with an annual development and growth strategy up to 2011, the project has been extended year by year and has now been active for nearly two decades. Beneficiaries continue to receive technical and material support, and the number of community gardens has grown. In 2019, the initiative expanded to include two bio-gardens in the Trujillo districts of La Esperanza and El Porvenir (7, 9). The project has contributed to improving soil quality, recycling and transforming waste, enhancing landscape aesthetics, reducing burning and waste accumulation, and implementing drip irrigation systems.

Trénnelle-Citron Experimental Garden
Trénelle-Citron, located north of downtown Fort-de-France and separated by the city bypass, La Rocade, was originally established in the 1940s by Black Martinicans migrating from rural areas. Today, the neighborhood faces significant economic and social challenges. In 2016, young residents from the neighborhood alongside a local NGO launched a grassroots initiative to improve their community. They transformed a former municipal quarry, which had deteriorated into an informal dump, into a thriving shared urban garden, benefiting the local population. This project, based on traditional ecological gardening techniques and the cultivation of native crops, aimed to revitalize Trénelle-Citron—a densely populated area grappling with social exclusion, a shortage of green spaces, and limited economic opportunities for its youth (Ref 2).
The garden, developed on municipal land with guidance from the Ypiranga Martinique NGO, support from the local school, and collaboration from various stakeholders, now plays a vital role in the area. It raises awareness about agroecology, offers socioeconomic opportunities, promotes healthier lifestyles, and fosters social connections among residents. Spanning approximately 1,000 m², the site includes an office, a covered area, tool storage containers, market garden plots, a composting area, and a chicken coop managed by a local resident (Ref 7). In Martinique, such shared urban gardens are increasingly seen as important tools for sustainable development (Ref 5).

Cerro de la Popa recovery Project
Reforestation project for the "Cerro de la Popa", which is Cartagena's highest point and one of the main tourist attractions because of the view and its colonial convent (Ref 6). The hill currently faces illegal occupation and environmental deterioration caused by deforestation, poor solid waste management, burning, logging, and the loss of vegetation cover (Ref 4, 5). The intervention in La Popa consists of reforestation activities, environmental education activities with children, and awareness-raising activities with adults about caring for fauna, flora, and water bodies (ref 2, 3). SSince 2020, the Establecimiento Público Ambiental (EPA Cartagena) has led the recovery initiative, prompted by the urgent need to counter the increasing encroachment by migrants and vulnerable populations (Ref 4). The project comprises reforestation efforts, environmental education sessions with children, and community outreach to raise awareness among adults regarding the protection of local fauna, flora, and water bodies (Refs 2, 3). As part of a broader municipal agenda, the initiative remains active, with the most recent intervention conducted on July 11, 2024 (Ref 2).
