The Three Mile Creek Hydrological Restoration
The Three Mile Creek Hydrological Restoration project is taking place in one historic channel of the Three Mile Creek, located east of Dr. Martin Luther King, Jr. Avenue, and covering approximately 1,800 linear feet (Ref 3). This project, led by the City of Mobile, aims to remove sediment from the stream channel. This segment of the Creek was bypassed with a straight channel in the early 1980s to control flooding in the area, thus accelerating the accumulation of sediments in the historic channel (Ref 1).
The project's goal is to restore and maintain the natural flow to the historic channel and create a connection to the City and County's Blueway initiatives (Ref 3). This will improve habitat conditions and water quality and help to protect the area’s estuarine and marine water resources (Ref 8). It will also contribute to revitalizing the Three Mile Creek Watershed and provide increased recreational opportunities for citizens, like kayaking and canoeing (Ref 6). Construction work occurred in 2022 and 2023 (Ref 3).
The Three Mile Creek Hydrological Restoration is a key component of the Mobile Bay Shore Habitat Conservation and Acquisition Initiative, which focuses on acquiring, restoring, and preserving habitats, including riparian, wetland, and upland areas that support various fish and wildlife species affected by the environmental disasters of the Deepwater Horizon oil spill that occurred in 2010 (Ref 1). The project spans three critical areas: 450 acres within the Three Mile Creek Watershed (as detailed in this project profile), 300 acres in the Dog River Watershed, and 40 acres of bay shore property in the Garrows Bend Watershed (with the latter two areas being part of separate initiatives) (Ref 4).

Medicinal plant library in Tivoli
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)

Maskinparken
Maskinparken is a new park covering 3700 m2 in the Lindholmen district, a new neighbourhood in a previous industrial/harbour area [Ref. 5]. The park is described as a well-needed green oasis or green lung in the developing area. The park finished construction in 2022 and is intended to provide access to green space for people living and working nearby. It is also designed as a blue-green stormwater management solution, where about 500 m3 of rainwater can be stored in the lower areas during heavy rainfall. Stormwater will be leaked from surrounding grey areas to the park to protect them from flooding. The Swedish National Board of Housing, Building and Planning (Boverket) has highlighted the park as a good example of climate adaptation in urban planning. The park has a variety of plants such as different tree species and flowering meadows, and plants that can withstand being soaked in the lower areas. Plants can grow in different landscape structures, such as hills and a pergola. The park also has amenities such as benches and lights, which are designed to mirror the style of the surrounding, older industrial brick buildings [Ref. 1-4].
Dodder Valley Park Wetlands
Two new wetlands were established in Dodder Valley Park as part of the Dublin Urban Rivers Life Project (DURL). This project aimed to create integrated constructed wetlands (ICWs) at strategic locations in South Dublin County to purify wastewater and storm-water before it discharged into rivers.
The ICWs consisted of a series of cells resembling shallow ponds, typically 200 to 300 mm deep. Heavily planted with specific vegetation, these cells treated water by removing nutrients and harmful impurities, resulting in cleaner, purer water being discharged. The water flowing into the wetlands came from wastewater of misconnected appliances and storm-water pipes located under public roads, which collected rainwater from roads, footpaths, and the roofs and patios of houses.
These wetlands also provided important benefits, including flood alleviation, bioretention of particulates and nutrients, improved habitat conditions, and enhanced biodiversity. The project aimed to promote the relationship between green infrastructure and public well-being, creating a complex biological system that supports a diverse range of plants, animals, microorganisms, and hopefully attracts frogs, newts, and birds.
To increase native biodiversity, the wetlands were designed with pollinator-friendly plants and trees, making them visually appealing for park users and the public. A Wetland Planting Day took place on September 9, 2022, with over 40 participants, including residents and representatives from local organizations. This phase of the project fulfilled not only the objectives of the LIFE project but also those of the River Basin Masin Management Plan 2022–2027, the Water Framework Directive, the Climate Change Action Plan, the Floods Directive.

Corridor of Cartagena - Barranquilla
The Cartagena-Barranquilla Road Corridor project, led by the National Infrastructure Agency (Agencia Nacional de Infraestructura (ANI)), covers 146.7 km to enhance connectivity between Cartagena and Barranquilla (ref 2). While primarily a transportation initiative, the project stands out for its focus on environmental conservation and community development. A major goal is the restoration of ecosystems and biodiversity protection. To this end, over 40,000 mangrove seedlings have been planted in the 34.13-hectare Ciénaga de la Virgen, a vital coastal wetland in Cartagena. These mangroves play a crucial role in restoring habitats, capturing carbon, and acting as natural flood barriers, thereby safeguarding nearby communities (ref 1,4,6). The project also tackles hazards like wildlife-vehicle collisions and habitat fragmentation. Seven wildlife crossings have been built to facilitate the safe movement of species, including the endangered Blue Crab (Cardisoma guanhumi) in the Ciénaga de Mallorquín. These crossings are essential for preserving local wildlife (ref 1,7).
In terms of socio-economic impact, the project has created over 9,000 jobs and established six bioclimatic nurseries, which provide sustainable livelihoods for communities in La Boquilla, Villa Gloria, Tierra Baja, and Puerto Rey. These nurseries support mangrove restoration and offer local people opportunities to participate in planting, monitoring, and maintenance activities. This approach fosters a circular economy, empowering community members, both men and women, to engage in sustainable economic practices (ref 1,2,6).
Overall, the Cartagena-Barranquilla Road Corridor is more than a transport project; it acts as a green corridor with a comprehensive approach that combines environmental conservation, hazard mitigation, and socio-economic development.

Emerson Elementary Tree Planting
Phoenix is grappling with severe urban heat problems. As the city continues to grow, it is expected to experience a rise in temperatures of three to five degrees on average in the coming years. This makes urban heat a significant concern, especially for vulnerable populations. Phoenix’s extensive urban sprawl, combined with a lack of green space, has exacerbated the urban heat island effect, where cities become significantly hotter than surrounding rural areas due to the high concentration of concrete, asphalt, and infrastructure. In 2022, Nick Lodato, the principal of Emerson Elementary School, wanted to mark the school's 100th anniversary in a meaningful way. He decided that planting trees would be the perfect way to celebrate this milestone while also benefiting the community. The tree planting event not only symbolized the school's strong sense of community but also represented an investment in its sustainable future. Prior to the project, Emerson had only 9% tree canopy cover, which was far below what is necessary to address some of the pressing environmental challenges Phoenix faces.
Tree cover has become critical infrastructure for heat mitigation. Trees provide natural shade and help cool the environment by reducing surface temperatures, which in turn lowers energy consumption and promotes better public health. In addition to offering shade, the native, drought-tolerant trees and plants planted at Emerson will also contribute to carbon sequestration, purify the air, and improve mental health by creating more green spaces for relaxation and outdoor activities.
To complete this project, Emerson Elementary partnered with the Arizona Sustainability Alliance (ASA), a local nonprofit. Together, they planted over 100 trees and plants across the school’s campus, with approximately 125 people attending the event. Volunteers included students and their parents, Tau Psi Omega fraternity members, APS employees, neighbors, former Emerson students and teachers. (1-3)

Kottedala biodiversity park
A biodiversity park was built on an abandoned plot of land that felt unsafe to local residents. In the future, the plot may eventually be used for the construction of something more permanent. In the meantime, this project seeks to increase safety and access to greenspace while benefiting biodiversity, specifically flowers and insects.
Recycled materials were used to create the structure of the park, places to sit and insect hotels, while trees and a flowering meadow were planted. A mix of annual and perennial flowers was used to promote biodiversity over time. The locals are reported to be happy with the project. Familjebostäder i Göteborg AB, a publicly owned real estate company, conducted the project. [Ref. 1-5]

Blue Pearls for Berlin
Berlin has faced severe water shortages in recent years, with ponds, small lakes, and pools suffering significantly. Many have dried out or disappeared, causing habitats for countless animals and plants to vanish. Urbanization exacerbates the issue, as more areas become sealed, preventing rainwater from replenishing soil and water bodies. Recognizing the urgency, Berlin introduced the Eco-Account, a strategic reserve of areas and initiatives to mitigate the effects of urban development on nature and landscapes. Central to this is the Blue Pearls for Berlin program, focusing on revitalizing small water bodies to restore biodiversity and ecological balance.
The project identified approximately 30 ponds, pools, lakes, and ditches from over 100 candidates to be transformed into "blue pearls." These revitalized areas will support local ecosystems and improve Berlin’s water cycle. The Berlin Rainwater Agency, alongside departments responsible for nature, climate protection, and water management, is spearheading the initiative in collaboration with the Berlin Nature Conservation Foundation.
Two pilot sites—the Schleipfuhl/Feldweiher water complex in Marzahn-Hellersdorf and the Lankegrabenteich in Steglitz-Zehlendorf—were prioritized for restoration in 2024. These efforts include improving water quality and creating diverse habitats for wildlife. Enhancing small water bodies not only provides a refuge for animals and plants but also contributes to climate adaptation. Restored ponds and lakes can cool surrounding areas and improve the urban microclimate by utilizing locally accumulated rainwater. Blue Pearls for Berlin, approved by the Senate in 2022, aligns with the city’s Eco-Account framework, ensuring that these restored blue spaces offset ecological damage caused by infrastructure and urban projects. The initiative offers Berliners new ways to experience nature, fostering a balance between development and environmental preservation. (Ref. 1, 2, 4, 6, 7)

D'Olive Watershed Restoration
The D'Olive Creek Restoration project is designed to address the significant environmental challenges facing the D’Olive Creek Watershed and its tributaries (Tiawasee and Joe’s Branch), primarily caused by increased urbanization. Over the last several decades, the area has experienced severe erosion, sedimentation, and habitat degradation due to stormwater runoff from new residential and commercial developments. This runoff has led to stream channel instability, loss of wetlands, and impaired water quality in both D'Olive Creek and Mobile Bay, threatening aquatic and wildlife habitats (Ref 2).
The project involves restoring degraded streams and implementing management measures to reduce the downstream impacts within the watershed. Key activities include stormwater retrofits, stream restorations, and continuous monitoring. These efforts aim to stabilize stream segments and significantly reduce sediment loading into the northeast quadrant of Mobile Bay. This is crucial for improving water quality and clarity, which is necessary for re-establishing submerged aquatic vegetation (SAV) beds that serve as critical nursery areas for shellfish and finfish (Ref 1). By using natural materials like rock and living plants, the project also seeks to create a sustainable and ecologically balanced watershed system (Ref 3).
The anticipated outcomes include enhanced water quality in D'Olive Creek and Mobile Bay, reduced erosion and sedimentation, and the restoration of vital habitats, which will contribute to the region's overall ecological health (Ref 1, 3). This restoration project is part of a broader strategy outlined in the 2002 Comprehensive Conservation Management Plan for the Mobile Bay Estuary (Ref 1).
