The Dublin Open Air Laboratory
The Ringsend Open-Air Laboratory project in Dublin, Ireland, is part of a broader effort to adapt urban areas to increasing climate change risks. This initiative focuses on installing green roofs and deploying a network of environmental sensors to enhance urban resilience. Launched in 2018 under the Horizon 2020 OPERANDUM project, the effort seeks to find nature-based solutions for climate change impacts worldwide. Led by the University of Bologna, OPERANDUM involves over 20 partners, primarily in Europe, working together to address environmental challenges like flooding, drought, and coastal erosion through the establishment of ten "Open Air Laboratories" globally.
In Dublin, the project aims to bolster flood resilience in Ringsend, a critical economic area near the city’s tech district, which faces substantial flood risks due to its low elevation and proximity to the Dodder River. This river, which flows through both rural and urban areas before meeting the River Liffey near Ringsend, has caused property and infrastructure damage from extreme rainfall and combined river and tidal flooding.
Green roofs play a key role in mitigating urban flood risks in this project. These rooftop gardens absorb large volumes of rainfall before it reaches the streets, easing the load on existing flood prevention systems like storm drains and gullies and reducing the need for additional "grey" infrastructure. Based on community insights and recommendations, construction has begun on a green roof on top of the CHQ building in Dublin’s Docklands, in partnership with Dogpatch Labs.Complementing this, over 100 sensors have been deployed in recent research trials across Dublin. OPERANDUM researchers are now building on this foundation to create a denser, more reliable, and cost-effective sensor network, with data from earlier low-cost sensor trials made publicly accessible via Dublinked, Dublin’s open data platform, and exploring the use of LPWAN for environmental sensing.

Community mangrove nurseries "Mangle Verde"
The "Mangle Verde" project is a community-led intervention aimed at reforesting mangrove areas in Cartagena, particularly around the Ciénaga de la Virgen and Ciénaga de Juan Polo. Initiated by Gloria Sánchez and other members of the Villa Gloria community, this project is a response to the environmental degradation caused by urban development, including the construction of a viaduct, and the damages inflicted by invasive settlements and pollution(ref 1,4). The primary goal of the project is to restore the mangrove ecosystems, which are essential for maintaining water quality, preventing coastal erosion and supporting marine biodiversity conservation (ref 4). In addition, this initiative provides socio-economic benefits by fostering ecotourism and increasing fish populations, which directly benefit the local fishing economy(ref 1). The "Mangle Verde" project emerged as a grassroots response to compensations granted by the Concesión Costera for the damage caused by infrastructure projects in the region. Local residents of Villa Gloria, recognizing the importance of the mangrove ecosystem, established nurseries in their homes where they cultivate three types of mangroves (ref 2,4). So far, the initiative has planted over 26,860 mangrove saplings and is committed to continuing the reforestation efforts, which also include cleaning and maintaining the canals around the mangroves (ref 1). Beyond ecological restoration, the project also addresses key environmental risks in Cartagena, including coastal flooding and habitat degradation, driven by both natural phenomena (e.g., tides) and human activities such as urban sprawl and illegal dumping (ref 6, 7).
Rehabilitation of Hon. John N. Michuki Memorial Conservation Park
The John Michuki Memorial Park was transformed from a vast dumpsite in 2008 and established in honor of John Michuki, the Environment Minister during the Kibaki administration, in 2012. Michuki garnered admiration and accolades for his enthusiasm and determination to clean and preserve the environment (Ref 1, 2). Situated along the Nairobi River, the park serves as a historically rich recreational facility (Ref 3).
However, several issues arose after the park was transferred to the county administration in 2013 (Ref 2). A section of the Nairobi River flowing through the park experienced severe environmental degradation due to illegal discharges and poor waste management, negatively impacting the riparian ecosystem and biodiversity (Ref 4). Additionally, the park became a refuge for drug users, street children, and thieves, with stray dogs posing safety threats in the area (Ref 1, 2).
As the first project within the Cleaning Up Kenya Campaign, the restoration of Michuki Memorial Park was launched in 2020 by the government (Ref 5). The park is now managed by the Kenya Forest Service (KFS) following a directive from the national government (ibid.). With funds from the treasury, a perimeter fence was erected, a 2.4 km walkway was constructed, and 4,200 seedlings and 6,357 indigenous trees were planted, along with the establishment of a nursery (Ref 1, 6). A total of 20,000 tons of solid waste were removed (Ref 6). Additionally, a community forest association was formed to ensure community engagement (Ref 2).

The Ballymun City Farm
The Ballymun City Farm project began as a grassroots initiative when local residents envisioned turning an underutilized green space into a vibrant community resource. Though initially rejected by the City Council, the project’s supporters recognized its potential to contribute to Ballymun’s environmental, social, and economic regeneration. With a vision to create something unique for the area, the farm was designed to foster community engagement, environmental education, and local sustainability. Over time, it has grown into more than just a recreational space—it has become a symbol of community resilience, offering people of all backgrounds and abilities a place to connect, learn, and grow together (4).
Situated on 6.6 acres provided by Dublin City Council, the farm aims to strengthen community bonds, enhance civic involvement, and combat social exclusion and isolation. It serves as both an educational and recreational space, providing opportunities for people of all abilities and backgrounds to engage with environmental topics, organic food production, native breed conservation, and traditional crafts. It is envisioned that the farm will include a designated ornamental garden, consisting of shrubs, flowers, grasses and bulbs, which will become a focal point for community activities/gatherings. In addition, we plan to install raised vegetable beds, fruit bushes.
Through urban food production and community gardens—effective tools for educating schoolchildren and engaging youth—the farm addresses the gap between food production and consumption, helping to increase appreciation for local food. Investments in green infrastructure like Ballymun City Farm also support urban and regional development, including the creation of jobs. (1, 2)

Therapy Forest - Rescue MI Nature Now
The Therapy Forest project in Nolan, Detroit, initiated in 2022 and completed in 2024, represents a step forward in urban renewal and ecological restoration, led by Rescue MI Nature Now (RMNN) and local volunteers. RMNN, founded in 2019, aims to transform vacant lots in the Nolan neighborhood—an area heavily impacted by the mortgage lending crisis—into green spaces that combat urban decay. The Therapy Forest, a 2.25-acre site, is designed as an accessible, restorative environment inspired by the Japanese practice of “Shinrin-Yoku,” or forest bathing, which encourages individuals to engage with nature through all their senses.
This project not only enhances the aesthetic appeal of the neighborhood but also serves as a habitat for native plants and pollinators, such as goldenrod and honeybees. Through a participatory planning and design process, RMNN has actively involved community members, particularly youth, in the development and ongoing maintenance of the forest. The project includes flowering beds, perennial gardens, and other landscaping features aimed at creating a serene and therapeutic environment.
The Southeast Michigan Resilience Fund provided key financial support, recognizing the project's potential to transform neighborhood decay into a green space that serves both ecological and social purposes. The Therapy Forest is expected to become a communal asset, offering hands-on learning opportunities for local students while also providing a peaceful retreat for residents and visitors.
By converting over 2.25-acre of vacant land, RMNN’s Therapy Forest stands as a model for how urban areas can reclaim unused spaces, fostering resilience, community engagement, and environmental stewardship. This initiative not only revitalizes the Nolan neighborhood but also serves as a beacon of hope and renewal, demonstrating the impact of green spaces on urban communities.

Chandler Park Marshland
Chandler Park, a historic park in Detroit constructed in the 1800s, underwent multiple expansions from 1922 to 1950 to include amenities such as a pool (later converted into a water park), a golf course, and public green spaces. In 2013, an expert panel recommended constructing a 2.5-million-gallon marshland within the park to provide a unique recreational and educational feature and incorporate green infrastructure principles for improved stormwater management. Completed in December 2019, the Chandler Park marshland was a collaborative project between The Greening of Detroit and the Chandler Park Conservancy, designed to enhance Green Stormwater Infrastructure (GSI) across 200 acres.
The marshland manages 2.5 million gallons of stormwater, substantially reducing the load on Detroit’s combined sewer system and minimizing basement flooding during heavy rains. Engineered with rain gardens, bioswales, and a pump system circulating up to 4 feet of water, the marshland fosters a balanced ecosystem with higher oxygen levels, benefiting local flora and fauna.
With 4,500 native plants, the marshland supports diverse wildlife, including migrating birds, turtles, frogs, pollinators like bees and butterflies, and natural mosquito predators. This project not only contributes to flood mitigation but also improves water quality by capturing stormwater and allowing pollutants to settle.
Additionally, the marshland provides a foundation for future environmental education, with plans to add an outdoor classroom and public learning spaces. The use of native plants ensures low maintenance and sustainability, requiring minimal water and fertilizers. By creating new habitats and recreational areas, the Chandler Park Marshland promotes biodiversity, environmental education, and community engagement, while alleviating urban runoff’s impact on Detroit’s sewer system.

Restoration of the Panke river
The Panke is a watercourse that rises outside Berlin and reaches the urban area of the city, flows through the districts of Pankow and Mitte and flows into the Berlin-Spandau Ship Canal in Wedding. The length of the Panke is around 29 kilometres. Almost the entire length of the Panke in Berlin (around 17.6 km) is to be renaturalised - on the section from the state border in the north of Berlin to its confluence with the Berlin-Spandauer-Schifffahrtskanal (BSSK). The Panke is currently a small watercourse that has been heavily remodelled by humans. In large parts of the watercourse, the banks have been straightened like a canal and reinforced with sheet piling, among other things. Existing riverbed drops and weirs prevent fish from travelling unhindered through the watercourse. Studies on water body (structural) quality, typification and other biological quality characteristics have shown that the Panke has poor status values in the majority of Berlin's sections, e.g. in terms of the fish population. The negative assessment results are primarily attributed to the lack of habitat and structural diversity, the lack of passability of the watercourse and, in some cases, high nutrient loads. (Ref. 1)
The restoration of the river was initiated by the State Berlin, following the European Water Framework Directive. The central aim is to implement flood plains and recreate the pre-straightened water course, to ensure space for flooding, habitats for more diverse flora and fauna, increase water flow for better water quality and create a site for recreation in a densely built city. (Ref. 1; Ref. 2) The project started back in 2003 and is expected to be finished in the 2030s (Ref. 2; Ref. 7).

Improving Ngong Hills Forest Conservation Efforts through Raising Local Community Awareness of Biodiversity Conservation
Ngong is a town in southern Kenya, located near Nairobi in Kajiado County, on the slopes of the Ngong Hills. The municipality has experienced significant development and population growth due to improved infrastructure and social amenities. However, this expansion poses a threat to biodiversity, as increased demand for agricultural land, wood, and raw materials is depleting the area's forests and putting many species at risk of extinction. Overgrazing, illegal logging, invasive species, and climate change-induced extremes like droughts and floods have further exacerbated the situation.
In response, the Rufford Foundation proposed the Improving Ngong Hills Forest Conservation Efforts through Raising Local Community Awareness of Biodiversity Conservation project. The initiative seeks to restore the Ngong Hills forest ecosystem through community-driven conservation. A nursery for native species was established, and tree planting campaigns were conducted in collaboration with national and local governments, community-based organizations, indigenous groups, and schools. Additionally, awareness programs and capacity-building efforts were launched, engaging local schools in restoration activities and organizing workshops to train community members and officials.

Santry River Restoration and Greenway Project
A new landscape plan for the Santry River, developed since 2019, envisions it as “the backbone of a green infrastructure project,” designed to support nature, pedestrians, and cyclists. The project will create a continuous route from the Dublin Bay Biosphere at St Anne’s Park to the wider hinterlands of Dublin at Sillogue.
The plan proposes transforming the Santry River into an “integrated green-blue landscape for ecology and recreation,” incorporating a variety of sports, cultural, and leisure activities. Through an agreement with Fingal County Council and the National Transport Authority, Dublin City Council has commissioned studies to address the existing flood risks along the river.
The council’s goals for the Santry River include river restoration, flood mitigation, greenway development, and environmental protection, extending from the river’s origin in Harristown within Fingal County to its outlet at James Larkin Road. The project framework will span four years, with annual reviews and budget assessments.
The project team has engaged the public in early autumn of 2022 to gather input on these plans, as the Santry River project aims to create a vibrant River Park that integrates natural and recreational elements. Running through North Dublin, this new green-blue infrastructure will serve both ecological and community needs, offering opportunities for sports, culture, and relaxation. Ultimately, it will form a natural corridor linking the Dublin Bay Biosphere at St Anne’s Park with Sillogue, promoting biodiversity while enhancing accessibility for pedestrians and cyclists (2).

Trees of Friendship
In 2020, the European Fund for the Balkans (EFB) launched the Trees of Friendship project, which plants over 400 trees annually across six Western Balkan capitals, known to be some of the most air-polluted cities in Europe (Ref. 5). Tirana has been involved from the start, having planted over 110 trees in locations such as Great Lake Park in 2020 and Farka Park in 2022 (Ref. 1,2).
The project is carried out with the support of local municipal and civil society partners, including Tirana's Parks and Recreation Agency and the Environmental Territorial Management Institute, along with activists and volunteers (Ref. 1,2). The initiative was planned in 2019 when the EFB board decided to mitigate its CO2 emissions from business-related flights and enhance local and regional cooperation on air pollution (Ref. 3,4,5). Despite challenges in citizen engagement during the COVID-19 pandemic, the Trees of Friendship project continues to raise awareness about the role of trees in mitigating the impact of air pollution on health and well-being (Ref. 2). Its strong and well-established local and regional partnerships have facilitated the project's implementation in the past and continue to benefit in scaling the project (Ref. 1,5).
