Resource Scarcity and Competition

The Productive Backyards Program is led by the NGO Granitos de Paz with the goal of promoting food security and income generation for vulnerable families in Cartagena. The program supports the creation of green gardens in household yards, provide technical training in planting, plant care, and supplies, as well as guidance and support for the creation of productive gardens, it also supports the commercialization of crops, fostering social cohesion within homes and positively impacting their environmental surroundings, nutrition, and health (ref 2, 3). A productive backyard is a small plot of land dedicated to growing vegetables for the family's daily consumption, providing fresh, healthy, and nutritious food. Family labour is utilised, offering both economic and nutritional benefits. This activity helps reduce malnutrition, improve the environment, and enable the commercialisation of organic products by making use of household yards (ref 6).
The program is led by the NGO and occasionally receives support from the mayor's office. The mayor's office has provided kits to the families with gardening tools, a watering can, mesh for enclosures, and seeds for 12 species, including tomatoes, sweet peppers, eggplants, bell peppers, Swiss chard, cabbage, and other vegetables. In addition to these supplies, families received training in entrepreneurship and business ideas for marketing their products, self-consumption, and all related concepts aimed at increasing production (ref 1 and 2). Currently, the program counts with 450 backyards in different neighbourhoods of Cartagena (ref 1).

The project consists in creating an urban orchard at a juvenile detention center. Strickland Youth Center welcomes troubled youth with the final aim of the intervention is to ensure a successful reintegration of youth into the community (Ref 4). The orchard is aimed to be maintained by the youth of the center, providing them with skills and preparing them for the job market (Ref 2). The orchard harvests will provide healthy food options for low-income and minority residents (Ref 1) in the surrounding neighbourhood that has been identified as a food desert (lack of nutritional options available) (Ref 2). The project also has an educational purpose on healthy food for the youth and residents (Ref 3). Besides, the orchard's green space aims to contribute to beautification (Ref 1) and to sequester carbon dioxide (Ref 1).

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).

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).
