Expected improvement in people’s connection to nature

The Çukurova Arboretum is located 17 km from the city centre of Adana, close to the Seyhan Dam lake. Established in 1997, it aims to conserve and protect plant species and vegetation from the region and those adapted to the Mediterranean climate (Ref. 2,5). Given its location outside the city centre and its proximity to freshwater resources, the Arboretum has been praised as a refuge for relaxation and recreation away from the stress of the city (Ref. 1,3). The area has been established by the Regional Forest Directorate of Adana in cooperation with the Istanbul University, department of Forestry (Ref. 2,3). In 2011 and 2013 new infrastructure was added to the arboretum, including a nursery, main road network connection and irrigation (Ref. 2). Visitors and researchers can access over 1050 ha hosting more than 700 plant taxa in different thematic areas, such as mediterranean vegetation, rose gardens, succulent and cactus areas, medicinal and aromatic plant gardens and an aquatic plants exhibition center which is a special feature to the site (Ref. 2). For research specifically, laboratory projects have been established and nurseries continue to ensure the supply of plant material (Ref.1). Over the years, the Arboretum has been equipped with more elaborate infrastructure and exhebition sites as well as educational material available to visitors (Ref.1,2,4).

The project to revitalize the Huveaune River and its biodiversity is taking place in Aubagne, a city within the Marseille Metropolitan area. For a long time, the river received little attention, constrained by urbanization, and was even covered for several hundred meters. Urbanization and the construction of a road have made the floodplain more susceptible to flooding (Ref 2). The initiative aims not only to restore the Huveaune and its environment but also to strengthen the connection between residents and the river (Ref 1) while reducing flood risk as a critical objective (Ref 1).
The challenge is transforming the area into a higher-quality environmental space with resilient ecosystems. A diagnostic conducted during the project's design phase revealed the site's degraded state, including the presence of invasive species, steep banks unsuitable for riparian vegetation, poor waterway conservation, and disrupted ecological continuity (Ref 2).
Key actions include revitalizing the river and its biodiversity, removing artificial banks, and creating new meanders to give the river a more natural shape. Diversifying flow patterns will create habitats for aquatic and fish species by varying water heights and flow speeds. This involves increasing the river's sinuosity and varying the width of the minor riverbed (Ref 2). Additional steps include planting trees and shrubs adapted to the Mediterranean climate with low water needs (Ref 2). To bring residents closer to the river, plans include creating walking and cycling routes, sports equipment, educational panels, and useful visitor facilities such as benches, water points, and restrooms (Ref 3).

The Adana Central Park stretches along both riverbanks of the Seyhan River. The idea was first introduced by the former mayor of the city, Aytaç Durak, in the late 80s to address the need for accessible green spaces in the developing area (Ref, 2). Previously, citrus gardens and informal settlements were located on these riverbanks, which now host over 400.000 plants and 67 different tree species on an area of 33 ha (Ref. 2,5,6). In 1998 construction of the park began, which lasted until 2004 (Ref. 2,5). The park is appreciated by visitors for its aesthetically landscaped appearance and the many amenities for children, youth, relaxation and socializing (Ref. 7). The two sides of the river are connected via bridges or, alternatively, visitors can board the Venetian style gondolas to access either side (Ref. 5). In 2021, park lighting infrastructure has been extensively replaced to ensure accessibility and safety during day and nighttime (Ref. 3).

The Grand Parc des Aygalades project involves the creation of a 14-hectare metropolitan park (connecting Aygalades Park with Bougainville Park and François Billoux Park) that will connect the northern neighbourhoods of Marseille to the port located further south (Ref 1). This project is part of the green conversion of Marseille's northern districts, historically among the most disadvantaged areas in France (Ref 1). The Grand Parc des Aygalades project will enhance the city's greenery, reduce flood risks, create cool zones, restore and develop biodiversity, and significantly improve residents' quality of life and air quality (Ref 1, Ref 2). The environmental and social challenges include reconnecting the populations of these neighborhoods to green spaces, services, education, sports opportunities (Ref 2).
The park project includes redesigning urban infrastructure to improve rainwater absorption and reduce flood risks, addressing the issue of impermeable and artificialized soils that exacerbate flooding during heavy rainfall (Ref 1). It also involves renaturing a 17-kilometre-long stream currently buried under railway tracks, improving flood management and rainwater drainage (Ref 1, Ref 4). The project will also convert a heavily degraded former industrial site, requiring the rehabilitation of polluted soils (Ref 1). Additionally, creating green corridors aims to mitigate the heat island effect, particularly severe in these northern districts due to the high concentration of buildings and concrete surfaces, and the lack of green spaces. Public participation will be encouraged through information meetings, thematic workshops, and an online platform for submitting ideas and feedback (Ref 4).

As part of France's New National Urban Renewal Program (NPNRU) and its strategy to enhance urban quality of life, the Urban Integrated Farm in Desclieux was established in 2021, with a particular emphasis on urban agriculture.
This project is implemented by the Centre de Culture Populaire Ypiranga de Pastinha Martinique (CCPYPM or Ypiranga Martinique) in collaboration with the city of Fort-de-France and is located in the socioeconomically disadvantaged Ravine-Bouillé neighborhood. It aims to create a farm on a 2-hectare former military site that previously housed fuel cisterns connected to the French Navy at Fort Saint-Louis. Since falling into disuse in the 1990s, only the reinforced concrete structures remain.
The farm will feature various activities, including a composting zone, a café, a beehive, a botanical trail, a play garden, and areas for crop and animal production. Additionally, it will house a decontamination and materials library and a public living space for community use. Overall, this site aims to serve educational, recreational, and socioeconomic purposes, enriching the local urban ecosystem.
Even though the intervention commenced in 2021 it has encountered several challenges since 2022 due to administrative hurdles. The implementers are currently awaiting temporary authorization to proceed. The primary obstacle remains the development and execution of a comprehensive soil decontamination plan. (Ref 2; 3; 4)

The Dog River Watershed Restoration project aims to protect and enhance the chemical, biological, and cultural integrity of the Dog River Watershed in Mobile County, Alabama (Ref 1). Guided by the Dog River Watershed Management Plan (WMP), the project addresses key issues such as pollution, litter, stormwater management, and habitat degradation (Ref 2). Funded by the National Fish and Wildlife Foundation's Gulf Environmental Benefit Fund and completed in partnership with stakeholders, the project focuses on implementing targeted restoration activities to improve water quality, protect critical habitats, and increase public awareness and access to the watershed (Ref 2). The Dog River Watershed faces significant hazards, including pollution, sedimentation, erosion, and the impacts of urban development (Ref 3). These challenges are intensified by the watershed’s role as an urban estuary, where land use heavily influences water quality and habitat conditions (Ref 3). To mitigate these threats, the project incorporates pollution prevention measures, shoreline restoration efforts, and community engagement initiatives (Ref 4). By prioritizing scientifically supported actions and aligning with broader environmental goals, the project seeks to restore ecological balance and ensure the long-term health and resilience of the watershed and its connected ecosystems in Mobile Bay (Ref 4).
The Watershed Management Plan for the Dog River Watershed is a key component of the Mobile Bay Shore Habitat Conservation and Acquisition Initiative, which focuses on acquiring, restoring, and preserving habitats and wildlife species affected by the environmental disasters of the Deepwater Horizon oil spill that occurred in 2010 (Ref 6). The project spans three critical areas: 300 acres in the Dog River Watershed (as detailed in this project profile), 450 acres within the Three Mile Creek Watershed, and 40 acres in the Garrows Bend Watershed (not in focus here) (Ref 7).

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)

At the beginning of the twenty-first century, Kunming’s urban planning faced major challenges, including fragmented development, environmental degradation, and limited green spaces (Ref 1). In response, the municipal government launched a series of strategic plans aimed at promoting high-quality urban development and environmental restoration.
Baisha Lake was identified as a key area in these strategies, with plans for Baisha Lake Park first highlighted in 2017 (Ref 2) and reaffirmed in the "Opinions on Supporting High-Quality Development in Kunming" in 2021 (Ref 2). To implement parts of this broader strategy, the government entered into public-private partnerships. In 2018, land development rights for parts of East Baisha Lake were granted to Dahua Group, on the condition that 40% of the area be reserved as green space and that ecological restoration efforts be undertaken (Ref 3, 4).
The Eastside Baisha Lake Park project, launched by Dahua Group in February 2023 (Ref 3, 5), is thus one component of this larger government-led urban renewal effort. The project follows the city's planning framework of “one lake, six zones, 46 scenic nodes” and includes 55 hectares of green space, with 40% designated as parkland. By the end of 2023, 6.5 hectares had been completed, and the south bank of the park opened to the public in September 2023 (Ref 3, 6).
The broader East Baisha Lake area's development was originally planned by the state-owned Kunming Urban Construction Company, but land rights were later transferred to Dahua Group. Thus, while a private developer is leading the construction, the project remains a part of Kunming’s publicly driven strategy to restore the lake and enhance urban livability.

Project Roots is a community-based nonprofit organization dedicated to fostering sustainable living and enhancing food security in South Phoenix, Arizona. Founded in 2020 in response to rising food insecurity—an issue impacting one in seven Arizonans—Project Roots aims to provide lasting solutions through community education, accessible fresh produce, and supportive services for vulnerable populations.
Central to Project Roots’ mission is its work in community gardening. The organization manages and maintains several community gardens, including 20 reserved rows at the Spaces of Opportunity Garden, where individuals and families can cultivate their own produce. Through these gardening spaces, Project Roots empowers community members to grow their own food, promoting self-sufficiency and healthier food choices.
Education is a cornerstone of Project Roots' outreach. The organization offers hands-on gardening classes, workshops, and educational resources that teach sustainable food production practices. A significant part of this educational effort focuses on South Phoenix's youth, helping them understand where their food comes from and how to grow it, fostering both awareness and skills that encourage lifelong healthy habits.
Project Roots also works to ensure that fresh, locally grown produce reaches the wider community. By distributing produce through farmers' markets, produce bags, and partnerships with local food banks and soup kitchens, Project Roots provides a consistent source of nutritious food to those who need it most. The produce bags, often delivered to community centers and low-income housing areas in Phoenix, help bridge the gap for those with limited access to fresh food.
In addition to its food-centered programs, Project Roots extends its support to include essential services such as food assistance, hygiene items, and temporary shelter, making it a vital resource for individuals and families experiencing hardship. (1-5, 8-14)

The Miraflores Bicentennial Park has been built on the Malecón de la Reserva and the Quebrada de Armendáriz. It was inaugurated in June 2022 as one of the created projects within the framework of the commemorations of the 200 years of Independence celebrations (1). It is considered a new green lung of Lima (2), as it has a green area of 30,400 square metres and stands on one of the cliffs of the Costa Verde (1). It has a system of terraces that replicates the construction model of the Incas, which has made it possible to additionally reinforce the soil and the slopes with the use of retaining walls up to 10 metres high, with horizontal geogrids and vertical geocells (1, 2). It was structured on a stabilised slope in order to mitigate the risk of landslides (4), and an irrigation system was implemented to stabilise the soil (4).
This space was built as a biodiversity garden with more than 160,000 xerophilic coastal species with low water consumption, 300 trees and 80 palm trees. It also offers places for tourism, such as viewpoints and squares, where cultural events, open-air activities and rest areas are held (1). It also aims to connect aspects of landscape conservation, preservation of biodiversity in the city, and the construction of a cultural landscape in which human action is complementary and friendly to the natural environment (9). Finally, it seeks to contribute to the reduction of the municipality's carbon footprint by reducing the harmful effects of urban expansion on the Lima cliff ecosystem, such as deforestation, water pollution and loss of biodiversity (9).
