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].

This project involves collaboration among government, private, and educational entities focused on developing an agroforestry initiative that integrates economic activity, labor market integration, and educational opportunities for young children at the “Foyer de l’Espérance” [school and child welfare center] in Fort-de-France. The objective is to plant 1,500 cacao trees on the Foyer's premises by 2025. These trees will serve as pedagogical support for teachers and children. Planting activities commenced in 2022, and the first cacao pods are expected to mature in 2-3 years. Subsequently, these pods will be processed and transformed by the Martinican Lauzéa chocolate factory under the brand “Chocolat de l’Espérance” (Refs 2; 4).
The idea for this project emerged in June 2022 when young students engaged in a discussion about cocoa farming with Thierry Lauzéa during "Business Thursdays," organized by “Espérance Formation Insertion.” These meetings allow young beneficiaries to explore the business world and discuss their career paths with professionals. During one of these sessions, the young participants inquired about the origins of the cocoa used in Lauzéa's chocolates, leading to the concept of producing cocoa for the Frères Lauzéa company (Refs 3; 5).

The Gnomes Project was launched to breathe new life into the abandoned Dublin City University (DCU) Community Garden, transforming it into a thriving urban micro-farm. Led by three friends—Martin, Jason, and Shane, collectively known as "The Gnomes"—the initiative grows pesticide-free, organic produce for the local community while championing regenerative farming practices.
The Gnomes employ bio-intensive agriculture, a sustainable approach designed to maximize yield from small spaces while maintaining biodiversity and enriching soil health. This method supports long-term productivity by promoting crop diversity, improving soil quality, and reducing dependence on external inputs through a closed-loop system.
The project’s journey began in 2015 when Jason and Martin enrolled in DCU's horticulture program and saw potential in the overgrown community garden. Shane joined as a volunteer in 2016, and by 2017, the trio had formalized their efforts to revitalize the garden. In 2019, they registered their business and began growing over 30 types of crops, eventually selling their produce through local farmers’ markets and small businesses.
Working tirelessly to restore the garden, The Gnomes cleared debris and removed invasive weeds using organic methods, transforming the area into a productive micro-farm. After negotiating with the university, they secured a lease for a 10,900 sq.-ft. plot (approximately 1/4 acre), with access to water. This space became the foundation for their bio-intensive, small-scale farming model, enabling them to grow quick-yield, high-value crops that thrive in limited spaces.
Some of their 20+ crops include a variety of leafy greens, herbs, tomatoes, cucumbers, zucchinis, green beans, onions, carrots, beetroots, baby turnips, apples, and recently added microgreens.
The Gnomes Project demonstrates the potential of urban farming, combining sustainable agriculture with community engagement. (2-5, 7-10)

The beach of Vétiver, located in the municipality of Case-Pilote, is one of the most important nesting sites for the critically endangered hawksbill turtle (Eretmochelys imbricata) in Martinique. It is also a nesting ground for the green sea turtle (Chelonia mydas), another endangered species. As one of the last minimally urbanized beaches in the North Caribbean of Martinique, the site plays a vital role in the conservation of these species. In addition, fishing restrictions in the area significantly reduce the risk of turtle mortality caused by accidental capture in fishing gear, which is the leading cause of human-related sea turtle deaths in the Antilles.
However, the site faces several stressors that hinder successful nesting. The surrounding vegetation is severely degraded due to invasive alien species, and much of the shrub and tree cover has disappeared from the backshore, where turtles prefer to nest. Without adequate vegetation, hatchlings are left exposed to the heat. Additionally, the beach is frequently disturbed by local residents and visitors for recreational activities. With no designated parking area, cars often park directly on the beach, compacting the soil and further limiting the chances for vegetation to recover or turtles to dig nests. This compaction forces turtles to lay their eggs closer to the shoreline, increasing the risk of nests being washed away by heavy swells.
In 2022, the non-profit organization "Asso-mer" and its partners launched the Véti’Vert project on a previously neglected public green space. Through environmental restoration efforts, they created a nesting enclosure on the backshore to mitigate these stressors and improve the conditions for sea turtle nesting. The project also engaged with local residents to increase the chances of success (Refs 1-3).

Airfield Estate, based in Dundrum, South County Dublin, is a dedicated sustainable food hub and Dublin’s only working urban farm and gardens. The 38-acre site, originally owned by the Overend family, attracts over 120,000 visitors for a fun day out including families, garden enthusiasts, schools, weddings and businesses.
The community garden at Airfield Estate is based on a partnership between the Estate and Toast corporation, a digital technology platform built for restaurants with an office in Dublin. The community garden was created to produce sustainable fruit and vegetables while also offering opportunities for people to learn about environmentally-friendly food production, empowering them to make more informed food choices. The Toast.org Community Garden at Airfield Estate will be a resource centre for education on nutrition, food sovereignty, seed saving, biodiversity, conservation, and resource management, supporting Toast.org’s mission to enrich the food experience for all. The community garden will also support Airfield Estate’s ambition to be Dublin’s sustainable food hub and help bring Dublin on its journey to be known as a world-leading sustainable food city (2, 3). The grounds will be accessible to everyone, from the local community and vulnerable groups to corporate employees, and the space will host horticulture talks and workshops on various topics. The partnership between Toast.org and Airfield Estate began in 2021 when some of Toast’s Dublin-based employees volunteered with the charity. The launch of the community garden is one of several ways Toast.org will support Airfield Estate throughout 2023. (2)

Lima is the capital of the region with the lowest coverage of green spaces. According to the World Health Organisation (WHO), a city should have at least 9m2 of green space per inhabitant. Lima is just over 3m2 square metres, which means a deficit of almost 60 million square metres. In this context, actions from the public and private sectors are essential to add this type of space to the city. In response to this need, Grupo Centenario carried out a green project on one of its plots of land in San Isidro, where real estate projects will be developed (1, 2, 3, 4).
A square was built with a green area with wild and low-consumption species, knocking down the walls that surrounded the land for years, turning it into a place for everyone to see and use (1, 2, 3, 4). The Choquehuanca Square was built to contribute to the community and make it a better place to live. It is located on a plot of land that was previously enclosed by walls, converting it into an area of 3,945 m2 with a green space that occupies 70% of the square (1, 2, 3). This is a temporary project, as the green space was opened while projects are being developed on this land (1, 2, 3).

The initiative involved the creation of three educational spaces in social service centers for children (Bucium, Ion Holban, Bogdanesti) in Iasi and its peri-urban area that included urban gardens, the development of green spaces, and facilities for sports activities. In the urban gardens, raised and arranged in a circular design, various orchards and food-producing plants were planted, along with bushes and perennial plants introduced in the new green spaces. Additionally, benches, workshop stations, a volleyball court, and a ping-pong table were constructed alongside the green areas.
The initiative was implemented by the NGO "Asociatia Outventure" and financed through the "In stare de Bine" program, funded by Kaufland Romania and managed by the Fundatia Pentru Dezvoltarea Societatii Civile (Foundation for the Development of Civil Society). The project also included training for permanent volunteers involved in the initiative and conducted 16 thematic workshops on healthy living and ecological behaviors.
The primary target group for the initiative was children and young people at risk of social exclusion, whose circumstances worsened after the COVID-19 pandemic. The objective was to provide them with "an alternative space to develop their personalities, as well as the necessary tools to adopt a healthy lifestyle in harmony with the surrounding environment." The project had a budget of 22,127 euros and was implemented over the span of six months. (1-5)

Over the past 10 years, Lima's population has grown from 8.2 to 9.6 million people. As the city's urban sprawl and population density have increased, green spaces have been replaced by grey infrastructure. Consequently, it has become challenging to ensure that residents enjoy a good quality of life (1, 2, 3). In December 2019, Lima City Hall launched "Limeños al Bicentenario," an initiative to revitalise the city's public spaces (1, 3). This program seeks to transform public areas through low-cost interventions, based on criteria such as vulnerability, citizen participation, and catalytic potential, among others (3). It also aims to foster social cohesion by involving residents in the maintenance of these newly renovated areas, while improving the city's resilience to climate change (1, 2, 3). Since its inception, the project has reclaimed 17 public spaces, covering an area of 41,000 m² (3). 430 trees have been planted, and the project has benefited from the collaboration of civil society and private sector partners (3). The programme also focuses on addressing climate change. Heat waves, droughts, floods and mass migration are the main climate-related risks affecting the city. In particular, the expansion of grey infrastructure at the expense of green spaces has exacerbated the risk of heat waves, causing temperatures to rise by up to 3.5 °C in certain areas of Lima (3).
One of the projects involved the recovery of public spaces in Teniente Pavia. For many years, the space was used as a public parking lot, and at night it accumulated garbage, there was alcohol consumption, drug use, and other problematic issues. There was no vegetation, benches or infrastructure for recreation. The neighbours, especially children, did not have access to green areas or recreational spaces (5). For this reason, in 2020 the project was initiated to repair sidewalks, plant vegetation, create gardens, and install infrastructure for play, rest, and exercise (3, 4).

Phoenix is grappling with severe urban heat problems. As the city continues to grow, it is expected to experience a rise in temperatures of three to five degrees on average in the coming years. This makes urban heat a significant concern, especially for vulnerable populations. Phoenix’s extensive urban sprawl, combined with a lack of green space, has exacerbated the urban heat island effect, where cities become significantly hotter than surrounding rural areas due to the high concentration of concrete, asphalt, and infrastructure. In 2022, Nick Lodato, the principal of Emerson Elementary School, wanted to mark the school's 100th anniversary in a meaningful way. He decided that planting trees would be the perfect way to celebrate this milestone while also benefiting the community. The tree planting event not only symbolized the school's strong sense of community but also represented an investment in its sustainable future. Prior to the project, Emerson had only 9% tree canopy cover, which was far below what is necessary to address some of the pressing environmental challenges Phoenix faces.
Tree cover has become critical infrastructure for heat mitigation. Trees provide natural shade and help cool the environment by reducing surface temperatures, which in turn lowers energy consumption and promotes better public health. In addition to offering shade, the native, drought-tolerant trees and plants planted at Emerson will also contribute to carbon sequestration, purify the air, and improve mental health by creating more green spaces for relaxation and outdoor activities.
To complete this project, Emerson Elementary partnered with the Arizona Sustainability Alliance (ASA), a local nonprofit. Together, they planted over 100 trees and plants across the school’s campus, with approximately 125 people attending the event. Volunteers included students and their parents, Tau Psi Omega fraternity members, APS employees, neighbors, former Emerson students and teachers. (1-3)

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).
