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).

The Mediterranean climate in Lisbon, already characterised by low precipitation, has been further exacerbated by climate change. The city faces challenges related to biodiversity loss, urban loneliness, and climate anxiety (1). To address these issues, Lisbon's urban development plans have prioritised the re-naturalisation of urban spaces and the integration of ecological networks. Urban nature is now a central component of the city's Master Plan (2012) and other strategic agendas (1).
It is being developed by the LISGREEN project, which aims to enhance ecological connectivity and mitigate the effects of urban heat islands in Lisbon. By establishing nature-based solutions, it aims to restore forests within the city (1, 2, 3). This project encompasses different strategies, such as the RENATURA pilot project. It is a collaboration with the NGO URBEM and involves active public participation in tree planting and forest maintenance. This initiative aims to educate the community about nature, promote well-being, and mitigate extreme climate events (1), through the creation of urban forests.
The main strategy is to create fast forests using the Miyawaki method, which involves dense planting of native trees, removal of invasive plants, and intensive initial care. This approach accelerates the growth of natural forests within a short period, using native species and reducing the need for watering (1)
The first fast forest was developed in Parque Casal Vistoso within Bela Vista Park, within the Eastern Green Corridor of Lisbon. The park is being underutilised because of the lack of shade (1). Thus, this initiative encouraged volunteers to participate in tree planting and forest maintenance activities (3). The NbS intervention began with a 300m² experimental plot near the Vale da Montanha pedestrian bridge and has since expanded to a new 1,500m² plot on the opposite side of the bridge (2). Over 500 volunteers joined the effort, planting more than 3,800 trees (1)

Lisbon is facing an increasing threat linked to climate change due to its geographical location and climate (6), which has had a negative impact on health and quality of life in the city (5). Its average annual precipitation is decreasing, although the city experiences more winter precipitation. This results in longer droughts and more seasonal flooding, which reduces water retention and soil conservation (6). Average temperatures are increasing by 14°C per year, with maximum temperatures up to 5°C higher (6).
As an adaptation measure to these challenges, the LIFE LUNGS project aims to increase Lisbon's resilience by implementing green infrastructure and promoting related ecosystem services (1, 3, 5, 6). Thus, it focuses on measures aimed at coping with temperature increase, mitigating the effects of heat waves and water scarcity, which are expected to become more frequent, being in line with the climate policies adopted by the municipality. The project runs from 2019/2020 to 2024/2025 (1, 5, 6). It aims to address cross-cutting issues such as climate, water and biodiversity (3). The project expects to work hand in hand with the City of Malaga, which has been developing projects aimed at adapting the city to climate change. It is expected to replicate the work in Malaga and post-project to 2 national territories, and 1 in the EU (4). It is also intended to transfer the project work to be implemented in private areas that are part of Lisbon's green infrastructure, and to disseminate and technically train municipalities of the Lisbon Metropolitan Area and other municipalities committed to climate change adaptation (4).

To reduce the risk of urban flooding, the city of Seville, through its metropolitan water company Emasesa, established several "sustainable urban drainage systems". One of the pilot locations is on the Avenida de las Ascociaciones de Vecinos, where a rain garden complemented by an infiltration zone was established. The main aim of the project is to reduce the risk of flooding, but the system can also improve the urban landscape by offering green space, preventing desertification and reducing pollutants carried by runoff [Ref. 1-4]. After implementation, the project was shown to be effective during heavy rain [Ref. 5]. The system can store up to 34 m2 of water and reduce flow rates to the sewage network by 69 % and the total runoff to sewage by 93 % [Ref. 3-5]. The project was initiated and led by Emamesa, while two different companies were employed to design and construct the system [Ref. 1, 2, 6, 7]. The total budget of the project, which also included some renovations of grey infrastructure along the street, was 165000 EUR [Ref. 1].

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).

This project aims to increase water retention capacity in the landscape around urban areas and promote biodiversity by restoring wetlands and natural streams in the forested areas on the island of Hisingen in northern Gothenburg. Many wetlands and streams in the area have been drained or otherwise affected by human activity, reducing biodiversity, increasing the risk of floods and droughts and causing greenhouse gas emissions from peatland. The goals of the project are to reduce the risk of floods downstream, reduce the effects of dry periods, increase groundwater infiltration and benefit species living in and around wetlands and streams in the forest [Ref. 1-3]. The Swedish Anglers Association has initiated the project in cooperation with the City of Gothenburg and the environmental engineering company Miljöteknik I Väst AB [Ref 1]. The project's first stage is a continuation of an earlier project to make an inventory of wetlands and their status [Ref 1, 2]. For the second part, 6,9 ha of wetlands and streams on land owned by the city were restored [Ref. 1, 3]. The project will lead to further efforts in wetland restoration around Gothenburg [Ref. 2, 4].

Pollinators—including bees, butterflies, moths, hummingbirds, sunbirds, and bats, all found in the Sonoran Desert—play a vital role in plant reproduction, contributing to the production of fruits, vegetables, and seeds. However, these essential species face growing challenges, such as habitat loss, pesticide use, and climate change.
In 2023, the Rio Reimagined project, a two-year regional river revitalization initiative, received a grant from the Society for Ecological Restoration’s Standards-based Restoration in Action program, in collaboration with Microsoft. This grant is funding the creation of a riparian pollinator garden designed by ASU students at the Nina Mason Pulliam Rio Salado Audubon Center, situated on the banks of the Salt River in Phoenix. With strong support from the City of Phoenix, Microsoft’s Community Environmental Sustainability (CES) program, and planting expertise from the Tiger Mountain Foundation, a one-acre garden was restored in 2024 to establish a thriving pollinator habitat.
This restored garden includes interpretive signage and programming designed to educate visitors on the importance of riparian ecosystems. More than one hundred volunteers planted native species along the Rio Salado to attract and support pollinators such as bees, butterflies, and birds. The garden is specifically designed to be climate-resilient and drought-tolerant, enhancing the biodiversity of the Salt River.
This initiative not only revitalizes the Rio Salado Audubon Center but also cultivates native plants, supports pollinator populations, and benefits the broader community through increased environmental awareness and sustainability. (1-3)

The Kikås dump is a landfill in Mölndal, south of Gothenburg, where an area has been permanently covered with a sealing layer and inert material. This project aimed to utilise the area to increase biodiversity by establishing flowering meadows and an insect hotel, creating a habitat for wild bees, butterflies and birds [Ref. 1-3]. The City of Mölndal initated the project and sowed meadow flowers, established sand beds for burrowing insects, an uneven, rocky terrain and a large insect hotel [Ref. 1, 3]. The area is also meant to be a destination for recreation and learning about biodiversity. The Insect Hotel is marketed as the largest in Sweden, and it includes information signs and an outdoor classroom. The project is meant to raise awareness about biodiversity and ecosystem services such as pollination [Ref. 1, 4-6]. The area borders natural areas such as forests and wetlands and is meant to have positive ecological effects in the border zones. The project will contribute to the environmental goals of the city, in particular, "a rich plant and animal life" [Ref. 3]

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.
