Increased knowledge of locals about local nature

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).

St. Anne's Urban Farm and Ecology Center, nestled within Dublin’s historic St. Anne’s Park and surrounded by the suburban neighborhoods of Dublin 3 and 5, is a unique not-for-profit initiative dedicated to community engagement, environmental awareness, and sustainable urban agriculture. Established in 2019, this farm is the first urban farm within Dublin City Council’s boundaries and aims to reach even more people, believing that every child and adult should have access to a garden space and that everyone in the garden is equal.
Run by a team of over 20 dedicated community volunteers, the farm provides hands-on educational experiences for visitors of all ages and a safe, open space for sharing knowledge and learning from others. Featuring traditional Irish farm animals, such as heritage breeds of chickens, pigs, and goats, alongside native plants grown from heirloom seeds, the farm preserves Ireland’s agricultural heritage while promoting biodiversity and sustainable practices.
With a goal of becoming 75% self-sustaining, the farm is working toward off-grid solutions through solar power and eco-friendly techniques. St. Anne’s Urban Farm empowers local residents with its community allotments and self-management model, which foster greater control and pride in maintaining the shared space. Aligned with Dublin’s Climate Change Action Plan, the farm aspires to improve the quality of life within the city by promoting healthy neighborhoods and sustainable communities. Through this green space, St. Anne’s Urban Farm encourages social and environmental engagement, aiming to ensure that gardens and green spaces remain accessible, welcoming, and educational for generations to come. The initiative is supported by a €50,000 donation from Google and is designed to serve as a community resource rather than a traditional petting farm.

In 2023, the municipality of Cagliari initiated a project to transform 50 school gardens into vibrant, multifunctional outdoor spaces that enhance education and recreation. Co-funded under an EU program, this initiative aims to create environments where students can learn and play outdoors, taking advantage of the city’s favorable climate. The gardens are being upgraded with new features, such as trees, educational vegetable plots, diverse plant species, playground equipment, and furniture, to provide versatile spaces for learning, sports, and play.
Automated irrigation systems are being installed in each garden, conserving water by adjusting based on soil humidity and detecting leaks. This technological upgrade ensures efficient maintenance of the green spaces.
Overall, the project seeks to enrich the educational experience by integrating nature into daily school life. It aims to promote students' physical and psychological well-being through more opportunities for outdoor learning and activities, fostering a connection with nature, and improving the overall quality of the school environment (Refs. 1, 2, 3, 4 & 5).

The Ciénaga de las Quintas is a coastal wetland located alongside one of Cartagena’s main roads, adjacent to the public market square and situated between the Jiménez and Bazurto Bridges. It is home to two predominant mangrove species (Ref 1). The wetland currently faces pollution problems because it is used for the disposal of solid waste, such as plastics and construction materials, and it receives wastewater and household garbage from nearby residences. Las Quintas is also the main waste disposal area for the Bazurto market, which handles 43,430 tons of food products each month (ref 3). The recovery initiatives for the Ciénaga de las Quintas are led by the Environmental Public Establishment of Cartagena (EPA Cartagena) in collaboration with other public institutions, the private sector, and citizens, with the main goal of achieving the ecological restoration of the city's water bodies and to maintain and preserve our mangrove ecosystems (ref 2). Since 2020, key implementation activities have included the removal of solid waste, planting of native tree species, dismantling of informal structures within the mangrove zone, and the rehabilitation of areas previously occupied by debris (Refs 4, 5).

Due to rapid urbanization and development, cities in China, including Kunming, face challenges in managing neglected urban spaces, particularly vacated demolition sites and leftover land (Ref 1, 2, 3). To address this issue and enhance residents' well-being, Kunming has created 400 pocket parks since 2022, transforming forgotten corners into vibrant green spaces (Ref 4, 5).
One of these parks, Wenxing Pocket Park in Xishan District, was built in 2023 on 2.3 hectares of land (Ref 6). Located next to a secondary school and two protected historical relics, the park not only preserves historical heritage but also reflects cultural value (Ref 6, 7). In addition to increasing urban green spaces, the park provides recreational and physical facilities for residents, children, and students (Ref 6). Its design is inspired by traditional architectural styles and incorporates wood craftsmanship, as well as ecological sponge facilities (Ref 6, 7).
The park also features science gardens, promoting awareness and knowledge of herbs and sustainability (Ref 6). The project employs methods such as infiltration, stagnation, storage, purification, and drainage to manage rainwater effectively. By utilizing the natural terrain, it creates ecological dry streams and sunken gardens that absorb and store rainwater, helping to control runoff. This approach aligns with the "sponge city" concept, promoting natural water accumulation, infiltration, and purification.
Additionally, the integration of various plants enhances the microclimate, supporting local wildlife and creating a healthy, vibrant public space. The Wenxing Pocket Park has been implemented by the Municipality of Xishan. (Ref.6,7)

The Urban Forestry Plan for Cartagena, led by EPA Cartagena, outlines a comprehensive strategy for enhancing the city's green infrastructure. The plan focuses on selecting suitable tree species, planting, and management to achieve several goals: reducing heat through shade, creating microclimates, protecting against climatic events such as coastal erosion and windstorms, enhancing food security, and enhancing the landscape's beauty. Over 10 years, the plan aims to establish at least 100,000 additional trees, increase overall tree cover, enhance accessibility to green spaces, and build a main ecological structure based on natural resources and biodiversity. It also emphasises the importance of local knowledge and resources (ref 1).
Formulated with community input, the plan commenced in 2013 and involved a detailed assessment of existing urban vegetation and climate conditions, utilising tools such as iTree. The development included international conferences and expert consultations to ensure a robust and informed approach (ref 1).

The Parque Lineal de Crespo in Cartagena, Colombia, is an urban green space built in 2016-2017 that had fallen into neglect (ref 4) and recently has undergone revitalization initiatives (ref 2). Announced in January 2024 by the Mayor of Cartagena, Dumek Turbay Paz, the project aims to reclaim and enhance this public park as a hub for recreation and community activities, fostering urban well-being and environmental stewardship​ (ref 2 and 3). The local government spearheads the intervention, and the Instituto Distrital de Deporte y Recreación (IDER) has been tasked with the park's management, ensuring its upkeep and the development of activities. The project was launched following an inspection by the Mayor and other local officials, who underscored the need for better infrastructure, safety, lighting, and green coverage through tree planting ​(ref 2 and 3). The primary objectives of the Parque Lineal de Crespo project include revitalising the park through enhanced maintenance, security, and the introduction of recreational and sports facilities. The project also aims to relocate weekend recreational activities, such as a popular bike path (ciclovía), from the congested Avenida Santander to the park, thereby reducing traffic disruptions and enhancing safety ​(ref 2 and 3). The park is relevant for the city because it combats coastal erosion caused by the rising Caribbean waters (Ref 1). The Park aims to be an icon of culture and recreation (ref 1). The project inspired a neighbours initiative, the Friends of the Crespo Linear Park, are a non-profit organization whose objective is to collaborate in the conservation of the Park by contributing awareness initiatives to the population, alerting authorities, and developing new ways to interact with the environment, such as guided bird watching activities and sports (ref 1).

An old park in Gothenburg was renovated to become "the world's best park when it rains" and attract visitors all year round. Rainfall is common in Gothenburg, but more importantly, the amount and intensity of rain are expected to increase in the future due to climate change. Municipal real estate company Higab had the park renovated to make the entrances more accessible and show that the park is open to everyone. A few rain gardens were created to better take care of rainwater, as well as a roof and sculptures interacting with the rain for aesthetic purposes. Additionally, existing plants and trees were cared for, and new ones were planted to create varied vegetation year-round. The area has been a park since 1860, therefore, efforts were made to preserve the historical space, such as using necessary amenities (benches, light sources) as well as improve the ecological function of the park. Special care was taken not to damage grown trees, such as the cherry trees, which blossom in the spring and are a popular attraction [Ref. 1, 2, 4, 5]

The Africatown Connections Blueway project aims to create a recreational water trail by linking 14 culturally and historically significant points along a 10-mile route (Ref 1). Central to this initiative is the preservation of Africatown's rich heritage and natural resources. The project seeks to reconnect residents of Africatown, descendants of the original founders of this self-governing community, which maintained a strong sense of African cultural heritage, to waterways that were historically vital for food, transport, and spiritual practices (Ref 1). By restoring access to these waters, the community can address both environmental and social issues, promoting eco-tourism and business growth while safeguarding cultural heritage (Ref 2). Local leaders emphasize the environment’s role in healing the community and preserving history, highlighting how this initiative can provide economic opportunities and improve quality of life (Ref 2). The project seeks to address the environmental injustices that Africatown communities have endured for decades. The area surrounding Africatown has long been dominated by harmful industries, including aluminium plants and paper mills, which have heavily polluted the water and restricted residents' access to it (Ref 1). With support from the National Park Service and contributions from Mississippi State University, the Blueway transforms neglected river access points into recreational areas, promoting environmental stewardship and cultural awareness (Ref 2).

The Lower Salt River Restoration Project (LSRRP) is a riparian restoration initiative located along the Lower Salt River within the Mesa Ranger District of the Tonto National Forest. This collaborative project seeks to restore a section of the Lower Salt River Recreation Area that was severely impacted by the 2017 Cactus Fire. The Cactus Fire was a significant wildfire that caused extensive damage to vegetation and habitat in the area, highlighting the need for targeted restoration efforts to rebuild the ecosystem and mitigate future fire risks.
The LSRRP’s primary activities focus on removing invasive tamarisk trees, which are highly flammable and contribute to the intensity of wildfires, and planting native seedlings to reestablish local flora. By removing tamarisk trees, the project aims to create a landscape that is more resistant to fire, reducing the wildfire risk for the region. Additionally, the project supports the abundance and diversity of native plant species by removing invasive plants and planting thousands of native riparian tree species.
The restoration efforts also aim to enhance the riparian habitat by expanding two critical vegetation communities—the mesquite bosque and the cottonwood-willow gallery forest. These communities support rich biodiversity and offer essential habitats for local wildlife.
Beyond ecological restoration, the project emphasizes community involvement and awareness. It provides opportunities for the local community to participate in the project through environmental education events for K-12 students and ongoing volunteer involvement in monitoring and maintaining restored areas.
Overall, the Lower Salt River Restoration Project is a proactive effort to protect and revitalize the Lower Salt River Recreation Area, enhancing its ecological resilience and engaging the community in long-term conservation. (2-4, 6, 8, 11)
