Knowledge creation and awareness raising

This project, implemented in several schools across Fort-de-France in 2018, focuses on creating arboretums in schools to educate children about Martinique's native natural heritage and raise awareness of biodiversity loss. An arboretum is a curated collection of trees selected for scientific, conservation or public enjoyment.
The initiative, led by the Martinican National Botanical Conservation, is supported technically by the municipal landscaping department and administratively by the city of Fort-de-France and the Martinican School Rectorate. It includes three main activities: a seminar on Martinique's rich yet fragile botanical heritage, an excursion into a forest, and a tree planting event at schools featuring native or endangered plant species. The program has reached at least six schools in and around Fort-de-France.

The Avas Tomato Community Garden, located in a formerly neglected area of the Avas hill of Miskolc, has transformed from an overgrown, rat-infested, and litter-strewn space into a thriving community garden. Just a few years ago, this site was a source of concern for local residents, plagued by issues such as homelessness and illegal dumping. Today, however, it stands as a flourishing green space with fresh garden beds, composting boxes, a pavilion offering shade to gardeners, and a renewed sense of community spirit.
The seeds of the Avas Tomato Community Garden project were planted in the fall of 2014, led by Zsolt Jakab and Ákos Káli-Nagy. The initiative began with the establishment of the "Panelkertész" club, and by 2016, with the support of a local representative, the garden began to take shape. The gardening community that blossomed in the spring of 2017 was built upon the strong relationships within the established Avas neighborhood. Working together, members constructed the garden beds according to a precise schedule and, through frequent discussions, developed a close-knit community. The garden now consists of 20 large and 6 smaller beds, with 18 families actively growing vegetables, herbs, and spices, alongside raspberry and strawberry plants by the fence.
The community has greatly benefited from both the professional support and supply donations provided by the Miskolc Ecological Institute Foundation. Additionally, the Dialóg Association has played a key role in organizing the garden users and fostering collaboration. Initially, Dialóg appointed a coordinator for the garden, but this responsibility has since been handed over to the gardeners themselves. Owned by the Municipality of Miskolc, the Avas Tomato Community Garden continues to thrive as a model of successful urban gardening, uniting people with a shared passion for gardening and a commitment to building a strong, supportive community.

The first medicinal plant library in Martinique was created by the Ypiranga Martinique association, which inaugurated the project in 2019. The initiative was developed to preserve and revitalize traditional knowledge of medicinal plants in Martinique, integrating agroecology , modern scientific understanding, and ancestral practices.
The project is located on land provided by the municipality in the Tivoli neighborhood, and it serves as an educational resource, a functional pharmacy, and includes a small shared vegetables garden. Visitors, local residents, and researchers can access information on over 150 native Caribbean plants and their medicinal properties. The site includes two educational trails: one following the river that crosses the garden and a sensory trail designed to help visitors "reconnect with nature." Each plant is identified with information boards detailing its medicinal uses, including whether these uses are scientifically validated.
The project also aims to address social exclusion by offering reintegration workshops to troubled teenagers and the unemployed.
The project was financed through a combination of sources: an EU-funded call for projects, a crowdfunding campaign, and regional and national public subsidies.
As a result of its success, in 2021 the initiative was formally replicated with the support of the Caribbean Interreg "OSAIN" project, which led to the creation of 14 additional plant libraries in schools and public spaces. Volunteers and community-based efforts continue to sustain the project, and it has become a model for similar initiatives. (Ref. 1,2,4,5,6,7)

Over the past two decades, as Phoenix’s population has surged since the 1990s, large expanses of farmland have been paved over to make way for urban development. This transformation has increasingly disconnected the city from its agricultural roots. In 2000, Janna Anderson recognized a growing need for local farms to strengthen their ties with the community and for increased access to fresh, locally sourced produce. With a vision to reconnect the community with its agricultural heritage, she purchased a historic orchard property in southern Phoenix, near South Mountain, in 2011. The property, which included a 1918 adobe home, was transformed into a thriving mixed-fruit orchard.
At Pinnacle Farms, Janna planted over 1,200 trees, including peaches, apricots, and rare Maktoom Dates, which were brought to the U.S. from Iraq in 1910. These heritage crops have unique flavors and textures not commonly found in grocery stores. In 2015, the farm became certified organic, underscoring Janna’s commitment to sustainable farming practices. Her focus is on cultivating varieties that are uniquely suited to the arid Southwest climate, using methods that conserve water and promote soil health.
Janna’s approach to farming also highlights the potential of heritage varieties to support food security in the desert. By growing these rare and resilient crops, she not only preserves biodiversity but also brings attention to how such practices can contribute to a more sustainable, local food system. Pinnacle Farms serves as a living reminder of Phoenix’s agricultural history, a place where fertile soil and sustainable farming practices continue to thrive. The farm embodies the deep agricultural roots of the region, connecting Phoenix’s past to its future and proving that the city’s rich farming tradition is far from lost. (1, 2, 6, 8)

The project at Poetto Beach in Cagliari, Italy, implemented by the municipality of Cagliari, began in 2022. It focuses on protecting and restoring the dune system while raising public awareness about the importance of preserving the coastal ecosystem. The project recognizes the delicate balance between environmental preservation and public enjoyment of Poetto Beach.
Key activities include installing barriers and signs to prevent trampling and littering, modifying beach access points to reduce erosion, and implementing significant interventions to restore the beach. These interventions involve strengthening anti-erosion measures with dune confinement and sand retention systems, as well as creating natural barriers (natural repopulation of native plants ) to protect the seashore. Public education initiatives aim to encourage responsible beach use and enhance understanding of the dunes' fragility. Additionally, new access walkways will be installed, and existing ones will be improved, including the creation of four wheelchair-accessible pathways to the water, designed for easy entry.
This comprehensive plan for protecting and enhancing Poetto's environmental resources is valued at €945,000 and is funded by the European Regional Development Fund.
Overall, the goal is to enhance environmental quality, promote sustainable beach use, and prevent both natural and economic losses. By balancing enjoyment of Poetto's natural resources with their protection, the project aims to ensure the long-term preservation of this valuable coastal area (Ref. 1, 2 & 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)

Urban areas are particularly vulnerable to climate change due to the extensive use of concrete and asphalt, higher levels of pollution, increased population densities, and the concentration of infrastructure, all of which amplify the effects of extreme heat, drought, and severe weather. Urban tree cover play a vital role in helping cities mitigate the impacts of climate change by reducing greenhouse gases and alleviating the effects of extreme heat and other climate alterations that negatively impact human health. In 2023, dozens of volunteers from Bethune Elementary School planted 33 trees on the school grounds to provide future shade and help cool the environment. The project was funded by Arizona’s Public Service (APS) Community Tree Program, which aims to reduce the urban heat island effect by increasing tree canopy coverage in vulnerable communities.
The initiative was driven by Trees Matter, a local nonprofit organization focused on enhancing tree infrastructure in schools while educating students and staff on the importance of trees and tree care. Involving children in the tree planting process allows them to take what they’ve learned in textbooks and apply it in real-life situations, while also fostering a sense of community and belonging. This hands-on involvement not only educates but also creates lasting memories. The project’s goal is to combat the urban heat island effect by expanding tree canopy coverage, thus creating cooler, healthier shaded spaces for students in areas of Phoenix most affected by high temperatures.
With support from APS and Trees Matter, the volunteers worked together to plant trees that will provide much-needed shade on the school campus. APS’s Community Tree Program aims to provide shade and cooler spaces in neighborhoods that need it most, helping to reduce temperatures by 20 to 45 degrees. This effort is part of a broader initiative to improve the quality of life and mitigate the impacts of extreme heat in Phoenix (1-5).

Maya’s Farm is a small, CSA (Community Supported Agriculture) sustainable urban farm located in Phoenix, Arizona, where urban development has limited farmland availability. In 2020 alone, Phoenix lost nearly 200 acres of farmland to urban sprawl, putting farms like Maya’s at risk. The farm faced potential closure until the City of Phoenix intervened, providing funding through the Farm Preservation Program, which established the city's first urban agricultural conservation easement. Maya's Farm strives to inspire a local appreciation for sustainable food and to bring renewed value to local food systems.
The farm’s mission is to provide accessible, fresh, locally grown produce to the community while promoting awareness of healthy, sustainable food practices. Through its CSA program, members receive a weekly produce box and have opportunities to come together, honor food traditions, and share stories over locally harvested food. As a CCOF (California Certified Organic Farmers) certified organic farm, Maya’s Farm is committed to organic practices that exclude GMOs, nurture the soil, foster biodiversity, and innovate growing systems. These methods result in healthy soil and cleaner air, contribute to carbon sequestration, and support critical wildlife habitats.
To broaden educational outreach, Maya’s Farm offers several programs that promote sustainable food practices, including its CSA program, an edible classroom series, and a partnership with Arizona State University (ASU). Through this ASU partnership, students gain hands-on experience by participating in daily farm operations.
Building stronger community connections is another cornerstone of Maya's Farm’s work. The farm collaborates with local restaurants, farmers' markets, and community groups to expand its impact. Maya’s Farm, ASU, and Arizona Sustainability Alliance launched an agrivoltaics project with solar-shaded crops. (2, 9, 11, 13, 15)

The Bela Flor Respira (BFR) project, also known as "ComBOA", is an urban agroecology initiative located in the Campolide neighbourhood of Lisbon, Portugal. This project exemplifies a transformative approach to community development and environmental sustainability by repurposing a neglected urban space into an agroforest. Launched in 2018 by the NGO Circular Economy Portugal, BFR engages local residents of the neighbourhood, from children to the elderly, volunteers, and academic partners, in creating a regenerative space that combines food production with social interaction (Ref 1). The project emphasises the co-production of public policies, fostering social cohesion through collective intelligence and civil society entrepreneurship (Ref 1). BFR’s innovative approach integrates syntropic agriculture, blending fruit trees, vegetables, and native species to create a resilient ecosystem that supports both the environment and the community. Through this initiative, BFR not only enhances urban green spaces but also strengthens community bonds, making it a model of sustainable urban development (Ref 3).

Fondo Unido Chihuahua, in collaboration with its corporate partners, is committed to raising awareness about environmental care and reforestation. One of its flagship initiatives is the annual tree-planting campaign, "Planting Today to Have Oxygen Tomorrow," organized by United Way Chihuahua in Ciudad Juárez. This environmental initiative focuses on improving the quality of different urban green spaces (parks, school grounds, streets) while fostering ecological awareness in vulnerable communities across the city. The primary objective is to plant a significant number of trees throughout Ciudad Juárez, using native species that are water-efficient and well-adapted to the local climate and soil. In 2022 the initiative aimed to reforest 18 parks located mainly in the south-eastern part of this border city with 1,000 trees. In 2023 and 2024 the intervention focused on planting 850 trees scatted all over the city.

The campaign brings together donations and volunteers through partnerships with various stakeholders, including local and regional governments, private companies, community organizations, and the general public.
United Way Chihuahua oversees the planning, coordination, and logistical efforts for the campaign. On planting days, volunteers gather at designated sites, guided by the organization to ensure successful planting efforts and community engagement (Ref 1-4).
