Food scarcity / security

Launched in 2022, the Murphy High School Farm-to-Table Program in Mobile is an initiative aimed at addressing urban food deserts and promoting community health through education and sustainable farming practices [Ref 1; Ref 4]. Funded by Spire as part of its “Connected Through Cooking” initiative, the program transforms 28 acres of school grounds into a teaching farm where students learn to grow and cook nutritious food [Ref 1; Ref 6].
The project integrates science, math, and culinary arts into hands-on learning, engaging students in planning, planting, and harvesting crops, as well as developing healthy recipes [Ref 1; Ref 4]. Activities include constructing greenhouses, building raised beds, and installing irrigation systems—33 raised beds and an 800 sq. ft. greenhouse were completed in the first year [Ref 1; Ref 2]. The program also supports nearby food-insecure neighbourhoods by distributing produce and recipe tips, helping address poor access to fresh food in Mobile [Ref 3; Ref 4]. Younger students from local schools are included through farm-based learning, broadening the program’s educational reach [Ref 1; Ref 5].
Key actors include Murphy educators, Spire staff, and community partners such as Jones Valley Teaching Farm and Auburn University [Ref 4]. Outcomes include improved STEM education, increased food literacy, and stronger community ties through urban agriculture [Ref 1; Ref 4].

HortaFCUL is a project created and managed by the Faculty of Sciences at the University of Lisbon to raise awareness and promote the practice of permaculture as a solution to the ecological, social, and economic problems the world is facing (1). This initiative began in 2009 on the University campus through a garden, which allowed HortaFCUL to start conducting some activities that could answer some socio-environmental challenges, such as food security and sovereignty, ecosystem degradation and climate change (13), by raising awareness, teaching, and practising many aspects involved in permaculture and urban agriculture (2). Its focus has been on regenerating soil in an urban environment and creating productive landscapes for people and other beings (12). They grow different types of plants (vegetables, shrubs, trees) in different ways (swales, raised beds, greenhouses) to increase plant diversity and foster ecosystems (13).
The project is managed by students and researchers, who hold educational activities, such as courses, workshops, and dissemination activities (events, discussions, fairs, and conferences) (2). The project is organised according to a non-hierarchical sociocratic model, in which all decisions are made as a group, and where all ideas, critiques, and suggestions are seen as added value and an opportunity to improve techniques and knowledge (3). Additionally, it is open to the community, allowing anyone interested to participate and volunteer (1).
HortaFCUL is also one of the pioneering permaculture projects in operation in the Lisbon region and is now recognized as a national reference centre for permaculture (2). Since its inception, HortaFCUL has sought to be a hub that attracts people, organizations, and other initiatives, and it is currently a point of contact between different projects and associations, such as local businesses, educational institutions, and networks (5).

Public spaces in Colombo are disappearing due to rising land prices, causing infrastructure issues that harm citizens' health, especially in low-income areas (3). One proposed solution to address the problems caused by rapid urbanization is the creation of community gardens, which can at least improve low-income residents' diets and immune systems and address malnutrition (3).
Considering the limited urban space for both citizens and other living beings, the organization Eco-friendly Volunteers decided to create a community garden. The Metta Garden in Colombo (1, 2) aims to bring back urban biodiversity through organic home gardening, generating healthy food for people and creating living space for many other animals and plants (2). Following the Buddhist concept of Metta (loving-kindness to all beings), it promotes walking meditation paths and facilities to experience nature using all five sensory organs (1), in addition to being a place for experiencing loving-kindness for both human and non-human living beings, seen and unseen (4, 5).
It has become a training institute for many stakeholders seeking to grow organic food and earn a better income through the high demand for organic products (2). At the same time, it serves as a biodiversity spot, attracting butterflies, bees, and other forms of wildlife to an urban environment (2).
The area is located in the middle of a semi-urbanized area, on the outskirts of Boralesgamuwa (2, 3). Maintained by a group of volunteers, it features a greenhouse and a plot of land of around 5,000 sq feet, populated with vegetable patches, a butterfly garden, flowers and rare medicinal plants (3, 4). The garden was divided into four sections representing the Buddhist elements: water, heat, air, and solid. Each section features specific plants and designs, like a pond for water, a compost pit for heat, tall plants for air, and a rock garden for solid. The layout follows a mandala design based on permaculture principles (4).

Mapinguari National Park, located in the Amazon region of Brazil, is a protected area distinguished by its rich biodiversity and vast expanse of untouched tropical rainforest (2). It was officially created on June 5, 2008, by decree, covering an area of 1,776,914.18 hectares (2). The Chico Mendes Institute for Biodiversity Conservation (ICMBio) manages the park. It is linked to a management plan encompassing several nearby conservation units and their areas of influence (2, 3). Its main goal is to preserve the valuable natural ecosystems and scenic landscapes of the Purus-Madeira interfluvial region, which includes savanna enclaves (2, 3). The ecoregion where it is located has a high priority for botanical conservation due to parameters such as species richness and endemism (3). Additionally, the area presents great environmental heterogeneity, with several isolated and unique ecosystems, aspects that have been considered for fostering scientific research and public visitation, with programs for environmental education, recreation in contact with nature, and ecotourism (3). On March 8, 2013, an advisory council for the park was established to involve various stakeholders in decision-making and the effective conservation of the park (2), and in 2018 a Management Master Plan was established, seeking to develop an integrated approach for the protection and proper management of the region, especially considering the socio-environmental impacts of the construction of the BR-319 highway and the deforestation caused by fires, the expansion of soybean cultivation, land appropriation (7) and cattle ranching from the neighbouring state (3, 10). It was established as a Natural Park in 2008, but over the years it has undergone changes in land regulations, adding or decreasing its size as certain mining activities have been allowed in the buffer zone (2)

In Phoenix, over half a million people are facing hunger, including schoolchildren, working parents, seniors on fixed incomes, and other marginalized groups. Factors such as limited food access and poor food quality—commonly referred to as 'food deserts'—worsen the problem. Food deserts are areas where residents have little to no access to fresh, healthy, and affordable food. Of the 55 food deserts in Maricopa County, 43 are located in Phoenix, affecting nearly half of the city's population
Agave Environmental Contracting, an NGO, is working to address food scarcity through education. The organization founded the Urban Farming Education (UFE) program to teach people how to grow their own food as a solution to food insecurity and to promote agricultural opportunities throughout the Valley. The goal of UFE is to educate individuals on creating their own gardens for sustenance, ecotherapy, social impact, and even urban farming for profit.
The program specifically targets schools, domestic violence shelters, homeless shelters, foster care prevention centers, and communities with disabled or elderly residents. In 2024, UFE partnered with the Valencia Newcomer School to install raised garden beds filled with roses and fruit trees. This project provided hands-on STEM learning during the installation, fostered networking opportunities through industry experts and community members, and helped promote the UFE program. It also highlighted how the initiative contributes to urban farming education and empowers local communities. (1-5, 7)

The rate of deforestation in the Brazilian Legal Amazon in 2023 was consolidated at 9,064 km2. Initiatives that promote forest restoration in this biome are emerging to overcome this scenario. One such initiative is Floresta Productiva which aims to reforest more than 200 hectares of degraded land in the southwest of the Brazilian Amazon, known as the ‘arc of deforestation’ (1). Led by the Instituto Socioambiental in partnership with the NGO Rioterra, it focuses on creating and disseminating native forest restoration models that combine ecosystem recovery with income generation for rural producers in Porto Velho (2). By fully integrating local communities, the project promotes traditional agroforestry practices (muvuca) and trains communities to maintain the planted land. This not only restores the forest but also provides economic benefits through the cultivation of timber, fruit trees and other species (2), strengthening sustainable agriculture, breaking the cycle of deforestation and restoring deforested areas through various native species grown in nurseries (1). The project is being developed in the cultivation area of the Amazon Bioeconomy Centre (CBCA), from 2023 to 2025, where it will directly benefit the rural community of Vila Nova de Teotônio (3).
The project started in 2019 and has impacted other communities in the area, such as the communities in Nova Mutum Paraná and Ji-Paraná (1). During these years, more than 123,000 trees have been planted in agroforestry on about 110 hectares of land, and edible forests have been created. Since 2022, a new planting phase has been underway, to plant more than 100,000 trees of 87 native species on 40 hectares of degraded forest (4). In conclusion, this project focuses on the development of agroforestry in the face of widespread monospecific soybean fields and intensive cattle ranching (3); the creation of edible forests (3); and the restoration of forest cover to ensure the long-term resilience of the forest (3).

Tirana's urban development has set a new record in 2022, when more than 1.8 million square meters of new buildings were constructed (Ref. 5). This rapid development increased the need for accessible urban green areas. At the Tulla Urban Farm, a wide audience is trained to create those green areas in their yards, balconies and roofs with the added benefit of growing produce for their own needs (Ref. 1,2,5). This practice of food autonomy is deeply rooted in Albanian culture but has been lost in urban settings where concrete has taken over the city (Ref. 1). Tulla Urban Farm addresses this issue by providing an inclusive space for people of diverse backgrounds to come together and experience urban gardening first hand under the guidance of professionals from the Agricultural University of Tirana (Ref. 2,3). In these "urban agricultural schools", workshops, seminars and discussions are held to re-cultivate traditional agro-cultural practices and knowledge that will benefit the participants, many of which are from marginalised backgrounds (Ref. 1, 4). All these activities are facilitated through the rooftop greenhouse of the Tulla Cultural Center, which harbours over 300 plants (Ref.1). As such, Tulla Urban Farm not only provides a space for experiencing and learning about plants but also for social interaction and building a community that also addresses more serious issues such as mental health in a society that faces high rates of unemployment (Ref. 1).
The project had received inital funding from the German GIZ in 2022 and won the Cultures of Resistance Award through which it financed the first two years of its programme and enabled free participation at the urban agricultural school for all participants (Ref. 2,4).

The urban farm of Lak'a Uta is an initiative launched by the NGO Fundación Alternativas, which established the first community garden in Bolivia, located in the city of La Paz at an altitude of 3,600 meters above sea level (1-3). The initial plan was to develop the garden on private land, but since the goal was to create an open space accessible to all citizens, the project eventually sought a public location (3). The subdistrict of Cotahuma granted them permission to use the Lak'a Uta park, an abandoned area rendered unusable by two landslides in the previous year (3). Through voluntary efforts and an investment of 2,800 euros, the land was transformed over three years to accommodate 40 plots of 16m² each, with individual families cultivating a variety of vegetables (3).
Now celebrating its 10-year anniversary, the project adheres to many principles of organic agriculture in an urban setting (5). The area has become a biodiversity hotspot, featuring an artificial pond, 16 wild plant species, and 39 fauna species, including 34 bird species, two types of frogs that provide natural pest control, and three bee species (3-5). Compost is produced naturally using waste management practices and worms (4-5). In addition to edible vegetables, the garden produces medicinal plants, some of which help stabilize the soil and prevent further landslides (3-4). The infrastructure also includes a rainwater collection system (3-5).
Originally, the project aimed to improve access to food, particularly in response to the growing urban population (1-3). Over time, it has also fostered a strong sense of community, while promoting urban gardening through educational workshops and disseminating information nationwide (1-5). It is estimated that 20,000 people have been educated on urban agriculture, healthy eating, and reconnecting with nature (5). The project has also contributed to shaping a local government law supporting urban gardening within the municipality (3).

Terres Sainville is one of Fort-de-France's priority neighborhoods, known for the precarious living conditions of its residents and the prevalence of illicit activities. Many plots of land in the area have been abandoned and are used as informal dumpsites. In response, the City of Fort-de-France developed the "Jaden Lanmou" (Garden of Love) program, which aims to revitalize neglected spaces across the city’s 145 neighborhoods, Terres Sainville being one of them.
With support from the Terres Sainville town hall, neighborhood associations (such as the Terres Sainville Citizens' Council and local schools), and the Ypiranga Martinique association, the community has been working to transform these wastelands into shared gardens. Since 2021, Ypiranga has created 10 productive gardens, designing each based on the land's configuration, soil quality, and the preferences of local residents, including options for market gardening, medicinal plants, fruit trees, and above-ground containers (Ref 1; 7).
This initiative prioritizes the development of city-owned land and strategic transit sites, while also encouraging private landowners to maintain their abandoned plots or share them with the community. Additionally, the program seeks to enhance existing flowerbeds, create new ones, and incorporate artistic elements like street art and graffiti. Public meeting spaces are being developed to foster community interaction.
The city aims to involve residents by providing equipment, training, workshops, and advice on best practices. Ultimately, neighborhood representatives and residents will be responsible for maintaining these new communal spaces and ensuring they are respected (Ref 2).

The Jardim do Caracol da Penha project transformed a vacant urban area into a community garden and recreational space in Lisbon. Initially planned as a parking lot, the project was reimagined by local residents, led by Rita Vieira Cruz, and submitted to the Participatory Budget in 2016, garnering over 9,000 votes (Ref 2). The one-hectare garden connects the Arroios and Penha de França parishes and features leisure areas, an amphitheatre, playgrounds, and a community garden (Ref 4). Its design was shaped by citizen input, emphasizing sustainability and accessibility, with plans to support activities such as outdoor cinema and community gatherings (Ref 2).
