Lightning Point Restoration
The Lightning Point Restoration Project focuses on protecting Bayou La Batre, one of the Gulf Coast’s few remaining working waterfronts. The community relies on fishing and seafood industries but faces increasing hazards from shoreline erosion, storm surge, hurricanes, and tropical storms. Past events such as Hurricane Katrina (2005) and oil spill (2010) caused major damage to infrastructure and livelihoods, highlighting the need for greater coastal resilience
Led by The Nature Conservancy and partners, the project combines engineered and natural approaches to safeguard the shoreline while supporting local livelihoods. Core activities include constructing approximately 1–1.5 miles of segmented breakwaters and jetties at the mouth of the Bayou La Batre River, and creating about 28–40 acres of coastal marsh, tidal creeks, and upland habitats using beneficially reused dredged material. Native planting and long-term monitoring support habitat performance and adaptive management.
These solutions aim to reduce wave energy, limit erosion, buffer storm surge, and maintain navigation, while restored marshes provide habitat for fish, shellfish, and birds. Designed to withstand nearly one foot of projected sea-level rise over the next 25 years, the project enhances shoreline protection, restores critical coastal habitats, and helps secure a resilient waterfront for Bayou La Batre’s economy and community (Ref. 1 - 4).

Eagle Reef Project
The Eagle Reef Project was launched to restore the health of Mobile Bay in response to habitat loss and declining fish populations due to the degradation of oyster and seagrass beds [REF 1, REF 6]. Originally planned in 2022 as an Eagle Scout service project by John Shell of Boy Scout Troop 147, the project has grown into a regional environmental initiative supported by Partners for Environmental Progress (PEP), the University of South Alabama’s Stokes School of Marine and Environmental Sciences, and municipalities such as the City of Fairhope [REF 3, REF 4, REF 7].
The project deploys preassembled mini reefs—constructed from plastic and PVC—beneath docks and piers across Mobile and Baldwin counties. These reefs, once colonised by filter feeders like oysters and barnacles, can filter up to 20,000 gallons of water daily and serve as habitats for fish, shrimp, and crabs [REF 1, REF 4]. The initiative aims to improve water quality, sequester nutrients, reduce algae, and restore marine biodiversity [REF 1, REF 6].
The Eagle Reef Project addresses critical coastal hazards, including water pollution, fish habitat loss, and the legacy of environmental disasters such as the Deepwater Horizon oil spill [REF 4]. It combines scientific monitoring, civic engagement, and scalable design to enhance the region’s climate resilience and ecological health [REF 1, REF 6, REF 7].

Municipal biodiversity conservation project
The Waliwa project, launched in 2017 by the municipality of Sainte-Luce, is a collaborative effort dedicated to restoring marine biodiversity, enhancing the ecological balance of the bay area, revitalizing the local ecosystem and supporting sustainable economic activities. By focusing on marine biodiversity conservation, Waliwa addresses several critical environmental challenges. The project helps mitigate coastline erosion, support the blue economy through artisanal fishing and tourism, and foster an environmentally friendly culture among the local community.
So far, the Waliwa project has implemented three initiatives: it restored the Gros Raisin backshore to address erosion and provide nesting sea turtles with protected space (Ref 4). The project also intervened to restore the Pont Café pond, which was covered in Salvinia Molesta, preventing the intake of oxygen and hampering its role as a water filter, habitat for species and flood regulator .
Furthermore, the project has conducted studies and raised awareness about the challenges posed by wastewater management on the health of municipal water bodies. Through these efforts, Waliwa is working to create a more sustainable and resilient marine environment for future generations. (Ref 4, 5, 6; 12)

Coastal erosion measures at Glose, Kungälv
The Swedish Geotechnical Institute, a government agency, and the county administrative boards in Västra Götaland and Scania are running a project which tests methods to prevent erosion of coastal salt meadows. Erosion risks destroying unique ecosystems, and the aim is to develop cost-efficient, nature-based mitigation methods that can be replicated in other sites with similar problems. The project is part of an EU-funded Interreg North Sea project called MAinstreaming NAture BAsed Solutions through COASTal systems (MANABAS COAST), which involves other countries in the region [Ref. 1, 5]. Four different salt meadows are included in the Swedish part of the project. The sites are called pilot areas and are meant to test and showcase NBS to inform policy and develop methods that can be used in larger scales in the future. One of the sites is located at Glose in Kungälv municipality within the Gothenburg FUA [Ref. 2-4]. Here, the biodiversity of a salt meadow used for grazing and the adjacent coastal waters are threatened by erosion. According to a new management plan, NBS such as natural barriers will be implemented to break waves and halt erosion, preserving the ecosystems, improving water quality and ensuring the land continued use as a pasture for grazing cattle [Ref. 4].
City of Fairhope: Working Waterfront and Greenspace Restoration Project
Fairhope's Municipal Pier is a popular bayfront destination featuring a 1/4-mile pier, swimming areas, picnic spots, a landscaped rose garden, benches, restrooms, a marina, a restaurant, walking trails, and a duck pond. However, the area has been fragilized over the years. The beaches are absent and less prominent now, due in large measure to the presence of shoreline hardening (Ref 5), making the shoreline more vulnerable to climate hazards (Ref 5).
The main goal of the Working Waterfront and Greenspace Restoration Project is to introduce safe and user-friendly improvements to the 10-acre South Beach Park area, which encompasses the Municipal Pier (Ref 2). These upgrades aim to enhance the public's use and access of the waterfront, while ensuring the park's long-term resilience and sustainability (Ref 2). The new design tackles both the structural issues of the bulkhead/seawall and the overall aesthetics of the Fairhope Pier area (Ref 2).
Over the years, storms, particularly Hurricanes Sally and Zeta, have compromised the structural integrity of the anchoring hardware of the bulkhead/seawall, causing parts of the wall to shift. Additionally, water intrusion behind the wall has eroded the soil supporting the walkway in certain areas (Ref 2). Other important features include new handrails, decking, restroom facilities, and lights on the pier. The project will also add new stairs leading to the bluff, restore the fountain, and renovate the parking lot. A funicular lift will be installed at the bluff to enhance accessibility (Ref 5).
Pedestrian safety will be improved to meet the requirements of the Americans with Disabilities Act. Other enhancements include landscaping with new irrigation, and the construction of new sidewalks (Ref 2, Ref 4).

"Green country" : planting 1 million trees
Martinique is a biodiversity hotspot, home to over 1,500 endemic plants, 70% of which are under threat from human activities. In response to these pressures, the Péyi Vert [Green Country] initiative was launched to plant endemic trees and strengthen the island's biodiversity. Beyond simply preserving species, these trees are crucial in maintaining healthy ecosystems, as they provide essential services such as carbon sequestration, shade, food for human consumption, soil decontamination, pollination, and protection against coastline erosion.
Launched in June 2020 by Entreprises et Environnement (EE), a not-for-profit business association representing 80 Martinican companies, the Péyi Vert initiative aims to plant 1 million native trees (either Martinican or Caribbean) over five years. It can be seen as a Martinique-wide strategy to adapt to and mitigate climate change. Péyi Vert facilitates connections between people who want to plant trees and Martinican companies that serve as financial sponsors. The initiative emphasizes conserving natural heritage by planting endangered species, as well as promoting native species that, while not necessarily threatened, provide valuable ecosystem services or contribute to biodiversity restoration.
Between 2020 and 2023, EE reported planting 50,000 trees (Refs 1, 4, 6, 7). Although individuals can make donations, Péyi Vert primarily seeks funding from companies looking to offset their carbon emissions or enhance their Corporate Social Responsibility (CSR). To achieve its goals, the initiative mainly collaborates with municipalities, companies, and farmers (Ref 3).

Extension of the Tagus Estuary Linear Riverside Park
The Tagus Estuary Linear Riverside Park is a significant environmental and recreational project in Vila Franca de Xira. As part of a broader urban regeneration initiative, the park aimed to enhance the natural and cultural landscape by promoting ecological regeneration while providing public access to the Tagus River (Ref 1). Created in 2013, the park has won several international awards and since then, the park has undergone several extensions. In 2017, another 700-meter walkway was added towards Santa Iria, and the inhabitants of this urban area of Vila Franca de Xira widely use it (Ref. 6). The park covers over 14 hectares and includes pedestrian and cycling paths, environmental education facilities such as the Bird Observatory, and the Environmental and Landscape Interpretation Centre (Ref 2).
Recently announced in 2023, the park's newest expansion is set to extend the riverside trails further, creating a continuous route from Lisbon to Alhandra (Ref 5). With future phases planned, the project is expected to significantly increase public interaction with the riverfront and its biodiversity (Ref 5). In this new project phase, the Vila Franca de Xira Municipal Council begins the requalification and environmental and landscape conservation of another section of the riverfront of the Municipality of Vila Franca de Xira, between Alverca and Sobralinho, covering an extension of approximately 4.9 km and an area of approximately 14.1 hectares (Ref. 7). The extension of the park will be developed similarly to its existing infrastructure. New paths for pedestrians and cyclists will be created using elevated wooden structures (walkways). In total, two new cycle-pedestrian trails will be created – Trilho das Comportas (3.32 kilometres long) and the Trilho dos Salgados (594 metres long) –, and the Trilho do Tejo will be extended by a further 990 metres (Ref. 5).

Cypress Shore Park
A new park is being planned for the Cypress Shores area in Mobile (Ref 1). Five civil engineering students from the University of South Alabama contributed to the design of the park (Ref 1). This collaboration offers students practical experience while providing city designers with innovative ideas for the site (Ref 2). The design emphasizes sustainability and cost-effectiveness (Ref 3). The project will feature a small park and boat launch on a 5.6-acre plot (Ref 1) located within a residential neighbourhood (Ref 3).
The park's societal goal is to improve public access to Halls Mill Creek, giving the community a new way to enjoy the waterway, and this focus aligns with the Mobile Bay National Estuary Program (MBNEP) goals (Ref 3). Historically, the property was used as a shipyard with a nearby railroad crossing (Ref 1), marking its transition from an industrial site to a public park.
Several amenities have been identified for the park’s development, including a boat ramp and kayak launch, a boardwalk adapted to sea-level rise, a pavilion and gazebo designed for flood resilience, a wetland nature trail with solar lighting and educational signage, and composting toilet restroom facilities (Ref 3). An armoured shoreline will be implemented to withstand medium water currents, and wave action will be constructed. Additionally, a living shoreline will be restored with local plants (Ref 3). While the project is still in its preliminary design phase, the timeline for completion is estimated at 12 to 18 months (Ref 1). The designers highlighted a potential trade-off, noting that an influx of visitors to the park could disturb the surrounding residential area (Ref 3).

Thessaloniki's New waterfront
Thessaloniki, Greece's second-largest urban center, is a key hub for economic growth and outward trade in the Balkans. The city hosts the country’s second-largest export port, which plays a crucial role in connecting European trade routes with Asia and China. However, until 2014, Thessaloniki's waterfront was poorly maintained, largely inaccessible, and unattractive. Moreover, major flooding events, connected to extreme weather events, exposed significant deficiencies in the city's flood mitigation infrastructure, leading to damage to housing and critical services. (5, 10, 11)
To address these issues, the Municipality of Thessaloniki launched an International Architectural Competition for the redevelopment of the New Waterfront. From 2006 to 2014, Thessaloniki's waterfront underwent a significant regeneration aimed at benefiting the city's population of 1.1 million and stimulating the local economy. The revitalized waterfront now stretches 3 kilometers between land and sea, featuring 58,000 acres of green space an playgrounds.. In total, 2,353 new trees and 118,432 plants were added across an area of 238,800 m² (Refs 1, 3, 4).
The project also introduced walking routes, sports and recreational facilities, seating areas, and scenic viewing points. The waterfront now has a bicycle path along the entire walkway, and an arbour of 660 umbrella pine trees, serving as shade from the midday sun. Completed in 2014, the New Waterfront has already become a vibrant urban green space, enjoyed by both Thessaloniki's citizens and visitors alike (Ref 4).

Sand Dunes Restoration in Almada
The ReDuna project, initiated in 2014, focuses on restoring the sand dune ecosystem in Costa da Caparica (Almada) in response to severe coastal erosion exacerbated by sea-level rise and winter storms. It aims to strengthen the resilience of dunes to environmental pressures while restoring ecological balance. Actions include sand nourishment, the installation of willow sand fences, and the planting of 100,000 native species. Community engagement was a key factor, involving local residents, NGOs, and schools in maintenance and replanting efforts. The project has been successful, with significant biodiversity recovery, establishing deep-rooted vegetation, and stabilising the dunes. Ongoing monitoring and adaptive management are central to its strategy, ensuring long-term sustainability. The ReDuna project serves as a replicable model for similar coastal protection initiatives globally (Ref 1).
