Agriculture/ crop production

The urban garden in Miraflores park (Huertas las Moreras) was established already in 1991 on an old waste dump and contains 10500 m2 of plots for locals to grow fruits and vegetables [Ref. 1]. The creation of the gardens was initiated by citizens who formed an association and implemented it in cooperation with the City of Seville. The citizens were discontent with the lack of green space in the area, and the urban gardens came to be alongside Miraflores Park, which was also pushed by the locals. The initial goals of the gardens were to allow locals to produce their own food and to host educational activities [Ref. 2]. More recent developments exemplify the focus on education and knowledge. In 2022, the citizen science project "Planta Bienstar" was carried out in the gardens, where high school students measured the lead levels in the soil and crops. The project aimed to investigate if lead levels posed a health risk and if the gardens could reduce levels over time. The project was organised by the non-profit Descubre Foundation and funded by the foundation and the regional Government of Andalusia. The project relied on the knowledge and efforts of the citizens, the students and gardeners in an intergenerational collaboration where the young could learn methods from their elders [Ref. 3, 4].

The Swedish Geotechnical Institute, a government agency, and the county administrative boards in Västra Götaland and Scania are running a project which tests methods to prevent erosion of coastal salt meadows. Erosion risks destroying unique ecosystems, and the aim is to develop cost-efficient, nature-based mitigation methods that can be replicated in other sites with similar problems. The project is part of an EU-funded Interreg North Sea project called MAinstreaming NAture BAsed Solutions through COASTal systems (MANABAS COAST), which involves other countries in the region [Ref. 1, 5]. Four different salt meadows are included in the Swedish part of the project. The sites are called pilot areas and are meant to test and showcase NBS to inform policy and develop methods that can be used in larger scales in the future. One of the sites is located at Glose in Kungälv municipality within the Gothenburg FUA [Ref. 2-4]. Here, the biodiversity of a salt meadow used for grazing and the adjacent coastal waters are threatened by erosion. According to a new management plan, NBS such as natural barriers will be implemented to break waves and halt erosion, preserving the ecosystems, improving water quality and ensuring the land continued use as a pasture for grazing cattle [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 Urban Center of Good Initiatives (CUIB), a social enterprise launched by the NGO Mai Bine in 2013, is designed to drive social economies and support sustainable development in Iasi. The enterprise operates a bistro that promotes social consumption by supporting local producers, adhering to slow food principles through the use of local and seasonal ingredients, minimizing food waste, and encouraging sustainable transportation, among other eco-friendly activities (2 & 4).
In 2020, CUIB and Mai Bine joined the FoodE program, a European research and social project focused on local agri-food systems. Funded by the EU’s Horizon 2020 Framework Programme for Research and Innovation (2014-2020), the initiative empowered grassroots organizations through co-creation and collaboration among diverse stakeholders (5).
The FoodE project strengthened CUIB’s mission to provide low-carbon-impact food, promote ecological, ethical, and artisanal products, offer solidarity services such as free meals for the most vulnerable, engage in low-waste operations, provide education on mental and human ecology, and foster community through social and cultural events (1, p. 98). To further these goals, CUIB organized co-design workshops with 100 community members, focusing on achieving zero food miles, zero waste, and eliminating food waste (1, p. 99).
The program also led to improvements at the bistro, including the creation of a courtyard garden, a small terrace garden, along with a community garden (1, p. 100). These gardens supplied food to the bistro, and bio-waste was composted to fertilize the plots (1, p. 102). CUIB also hosted 17 outreach events as part of the initiative, including ecological workshops and the creation of a vegetable garden at a local kindergarten (3, p. 114 & 6).
Beyond its environmental work, CUIB provides free meals for 100 beneficiaries and organizes food donations for 400 vulnerable children and individuals (1, p. 103).

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)

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)

The initiative focuses on the creation and implementation of a management plan for the Natura 2000 areas of Ciurbesti Lake and Fânațele Bârca to protect their biodiversity and promote sustainable tourism and land use. These areas were designated as part of the Natura 2000 network in 2016, but until recently, lacked a formal management plan. In 2019, the environmental group "Asociaţia Scutierii Naturii Bacău," in partnership with the Environmental Protection Agency of Iași (APM Iași), secured EU funding to develop the plan. While the plan was being developed, minimal regulations were established in 2022 to ensure interim protection.
The finalized management plan was released in 2024. It assessed species and habitats of European, national, and community importance, identifying 18 bird species, 3 plant species, 1 mammal species, and 4 key habitats. The plan also identified environmental pressures and set objectives and actions to ensure the conservation of this biodiversity. Before the plan's completion, two rounds of public consultations were held, involving a broad range of stakeholders, including surrounding municipalities, private landowners, public administrators, and local community representatives, to define optimal management practices.
The plan mandates continuous monitoring and reporting on the state of species and habitats. It also includes specific conservation measures, such as the partial reconstruction of endangered habitats, meetings with local land users to restrict harmful activities, public awareness campaigns, and regular monitoring. Additionally, it emphasizes the sustainable use of the area, including tourism. The creation of the plan was financed with EU funds totaling €1,036,014.27, and the projected cost for its implementation is €259,627.99. (1-5)

According to data from the National Institute for Space Research (Inpe), Rondônia ranks fourth nationally among the states with the highest number of detected fire outbreaks (2). In response to this issue and to restore devastated areas in the Amazon, Terra Cura was established in 2016 by resident Luana Lopes, promoting the planting of more than a thousand trees in the Porto Velho region (1). The areas benefiting from this initiative were those degraded by deforestation, causing erosion along the riverbanks (1).
This reforestation effort took place in the scenographic city of Jerusalem of the Amazon, from 2016 to 2022, a cultural and touristic complex in Porto Velho, where erosion caused by deforestation was observed along the riverbanks next to it (2). It was developed as a collaboration with the club and the founders of the Associação Clube Teatral Êxodo, who gave the space so that we could recover the land (3).
The project focused on developing an agricultural strategy known as syntropic farming, by implementing an agroforestry system. This approach seeks to reorganize and restore the natural environment, creating better conditions for planting and allowing trees to thrive. In the reforestation process, volunteers and experienced technicians worked together Additionally, the project included a nursery used for donating seedlings and for offering forestry and agro-construction courses to the community, held in the reforestation area (2).
The Terra Cura project, in addition to working on reforestation and recovery of degraded areas, promoted environmental and cultural integration at the site, promoting sustainable fairs and bazaars, training courses in ancestral practices such as soil cultivation and bioconstruction, and thematic events, bringing together artists and local communities (3). Although they were evicted from the area surrounding the scenic city of Jerusalem (5, 6), they are still active in the area.

The Growroom is a spherical urban garden made of plywood, designed as a temporary installation in Gdańsk’s Strzyża district. Originally created by Danish architects Sine Lindholm and Mads-Ulrik Husum, the structure was adapted for this location as part of a collaborative initiative. It provides a small, functional space where residents can plant and enjoy greenery within the city.
In Gdańsk, the Growroom was used to cultivate flowers, herbs, and strawberries, with the plant selection curated by Joanna Paniec, a specialist in the city’s green initiatives. A central bench within the structure offers a simple resting spot for visitors. While visually appealing, the installation primarily served as a short-term experiment in integrating greenery into urban settings.
The project was co-financed by the Danish Cultural Institute, the Danish Ministry of Culture, the Danish Ministry of Foreign Affairs, and the Environmental Department of the Gdańsk City Office. It was brought to Gdańsk by the Polish foundation Kultura nad Kulturą and conceptualized by Agnieszka Wołodźko, a painter, exhibition curator, and author of the blog Pomiędzy sztuką a życiem. The installation was in place from [add dates if available], after which maintenance was handed over to the local community.
The Growroom was not intended as a long-term urban feature but rather as a temporary initiative to explore the role of small-scale green spaces in cities. While it provided a brief opportunity for local engagement with urban gardening, it was ultimately a short-lived addition to the district. (1-4)

Martinique is a biodiversity hotspot, home to over 1,500 endemic plants, 70% of which are under threat from human activities. In response to these pressures, the Péyi Vert [Green Country] initiative was launched to plant endemic trees and strengthen the island's biodiversity. Beyond simply preserving species, these trees are crucial in maintaining healthy ecosystems, as they provide essential services such as carbon sequestration, shade, food for human consumption, soil decontamination, pollination, and protection against coastline erosion.
Launched in June 2020 by Entreprises et Environnement (EE), a not-for-profit business association representing 80 Martinican companies, the Péyi Vert initiative aims to plant 1 million native trees (either Martinican or Caribbean) over five years. It can be seen as a Martinique-wide strategy to adapt to and mitigate climate change. Péyi Vert facilitates connections between people who want to plant trees and Martinican companies that serve as financial sponsors. The initiative emphasizes conserving natural heritage by planting endangered species, as well as promoting native species that, while not necessarily threatened, provide valuable ecosystem services or contribute to biodiversity restoration.
Between 2020 and 2023, EE reported planting 50,000 trees (Refs 1, 4, 6, 7). Although individuals can make donations, Péyi Vert primarily seeks funding from companies looking to offset their carbon emissions or enhance their Corporate Social Responsibility (CSR). To achieve its goals, the initiative mainly collaborates with municipalities, companies, and farmers (Ref 3).
