Brookley by the Bay
Brookley by the Bay is a 98-acre new waterfront park project along Mobile Bay's western shore (Ref 1). The park aims to reconnect people with the Mobile waterfront and coastal ecosystem (Ref 2). The area, once an abundant mosaic of tidal marshes, forested wetlands, and shallow lagoons, became a port, leading residents to lose contact with the natural landscape (Ref 2).
The park serves both recreational and environmental purposes, aiming to create and restore areas that enhance habitat resilience and allow coastal ecosystems to thrive (Ref 1). It features sports facilities, including kayaking, volleyball, golf, and biking, along with social gathering and educational spaces such as an amphitheatre lawn, a performance pavilion, and picnic tables (Ref 3, Images 1-3). The park provides safe and equitable access for all Mobile residents to nature, beaches, tree canopies, open fields, and varied shorelines, all connected by pedestrian and bike lanes (Ref 2). The project also focuses on habitat enhancement and restoration for biodiversity (Ref 3, Images 1 & 4), as well as flood protection through shoreline get-downs, vegetated edges (Image 4), and undulating berms and swales that serve as a layered protection system against stormwater and coastal flooding (Ref 2).
The development of Brookley by the Bay was guided by input from over 300 community members (Ref 1), local stakeholder organizations, and project partners, with the goal of establishing a more resilient, accessible, and enduring space for generations to come (Ref 2).

The Three Mile Creek Watershed Restoration
The Three Mile Creek Watershed project is part of the City Council watershed management plans (Ref 2) to stabilize the banks and the stream along the Twelve Mile Creek and Langan Park Lake, both of which drain into Three Mile Creek and Mobile Bay (Ref 1). The project aims to address the issues of degradation of the banks and destabilization of the creek, undercutting of sanitary sewer crossings and sedimentation in the creek and Langan Park Lake because of the increased water flow speed due to stormwater conveyance (Ref 2). Besides, major pollutants from run-off and sewage water contribute to the degradation of Three Mile Creek (Ref 5). Key initiatives include stabilizing the banks and streambed of the Twelve Mile Creek, dredging and restoring Langan Park Lake, and implementing instream structures to reduce erosion and protect infrastructure (Ref 2). The project also emphasizes reducing pollutants from stormwater runoff, improving water quality, and helping to protect the area’s estuarine and marine water resources (Ref 1). The project will increase natural habitat and contribute to regulating biodiversity by aiding in the abatement of invasive species such as the apple snail (Ref 2). It is expected to contribute to enhancing recreational access through the development of trails, educational programs, and water sports facilities. The overall goal is to restore ecological health, support flood control, improve the quality of life in the Mobile and Prichard communities and make the Three Mile Creek a recreational destination (Ref 6).
A Green Promenade for Cagliari
Cagliari's waterfront is currently characterized by extensive soil sealing, which has rendered the soil impermeable, leading to a loss of biodiversity and contributing to the urban heat island effect. Additionally, the waterfront is disconnected from the city due to heavy traffic. In 2023, the Municipality of Cagliari launched the "Green Promenade for Cagliari’s Seafront" project, aimed at revitalizing the waterfront and reconnecting the city with its coastal heritage. Led by Stefano Boeri Architetti, the project seeks to transform the area into a continuous green space that integrates pedestrian pathways with shaded public areas, functioning as a "green lung" to mitigate urban heat and enhance biodiversity.
The initiative will introduce over 200 new trees and 5,700 square meters of green space, creating a park that beautifies the area, improves air quality, and lowers local temperatures. A key focus of the project is fostering cultural and social inclusion by developing new community hubs that encourage diverse activities and strengthen social cohesion. Additional features include recreational areas, sports fields, and outdoor seating. (Ref. 1, 2,3)
The project also aims to enhance social inclusion, environmental sustainability, and urban connectivity, ultimately transforming the waterfront into a vibrant public space that reflects Cagliari’s identity.
However, the lengthy construction process has disrupted local businesses and reduced foot traffic, making the area less attractive during the redevelopment phase. (Refs. 10, 11, 12 & 13).

Slowing down the erosion of the 'Salines' beach
Salines Beach, a popular destination for over a million visitors annually (Ref 9), is facing severe erosion due to rising sea levels and poor coastal management. Since 1995, the beach has lost more than 20 meters in width. This loss has been worsened by vehicle traffic and the introduction of coconut trees in the 1950s, which reduced the native root systems that once helped to stabilize the coast (Ref 5). Now, the encroaching sea threatens to swallow the road that runs along the beach.
In response, the Salines Conservation Committee—comprised of concerned community members and environmental groups—has been advocating for urgent action to halt the erosion. They have called for a renaturalization of the area through the replanting of endemic species and restrictions on car traffic, both aimed at restoring the beach’s natural resilience.
When part of the road collapsed in July 2022, the committee took immediate action, organizing community-based interventions. These efforts included blocking traffic, raising public awareness, and planting over 60 endemic plants in the damaged area. The aim was to reestablish a root network capable of anchoring the coastline and capturing shifting sands (Ref 1; 2). The intervention was described as "a response to the urgent need to rebuild the root network, an ecological engineering solution recognized as the most effective method for retaining beach sand and slowing coastal erosion" (Ref 2; 1). The intervention on this section of the coast was first completed, then discarded by the municipality of Sainte-Anne (Ref 2). Regional and National agencies are currently undertaking the restoration works but it is unclear the stage of completion (See Ref 3).

Saving the mangrove of Morne Cabri
The mangrove area of Morne Cabri, located in the municipality of Le Lamentin and sharing the bay of Fort-deFrance, is the largest mangrove area in Martinique. Since 2011, the municipality has led efforts to understand and better manage the area (Ref 1). The natural regeneration of the mangrove is threatened by fresh water run-off (from waste and rainwater), invasive species and pollution. However, it is an important protection against extreme weather events, operates as a carbon sink for the island and provides recreational activities (Ref 1). The municipality has led several initiatives supported by volunteers, local businesses, national subsidies and private donations (See: Ref 2, 3, 4, 11).
Deer River Coastal Marsh Stabilization and Restoration
The Mobile Bay National Estuary Program is one of 28 National Estuary Programs established by the United States Environmental Protection Agency, focused on safeguarding and restoring the water quality and ecological health of nationally significant estuaries (Ref 2). One of the four main areas of work of the project (Ref 2) is focused on Ecosystem Restoration and Protection (ERP), aiming at restoring and protecting ecosystem function and services (Ref 4). One of the projects implemented in 2023-2024 in the ERP category is the Deer River Coastal Marsh Stabilization and Restoration project, aiming at restoring and protecting the saltwater marshes of the area (Ref 8).
The issues faced in the Deer River Shoreline are shoreline recession, marsh deterioration, and loss of natural function from erosion, apparently caused by heavy storms, tidal impacts, and wakes from cargo ships entering or exiting the Theodore Ship Channel (Ref 8). Indeed, the saltwater marshes of this area have started to erode at a rapid rate, up to 12 feet per year (Ref 7).
The project aims to enhance the natural function of ecosystem services to improve the area's resilience. It will restore the eroded marsh by creating offshore structures to protect the shoreline and attenuate the waves. The project also aims to restore the water quality of the Deer River by dredging it out, thus improving the water flow. The material dredged out will be used to nourish the marsh (Ref 9).

Mangrove Protection Project for Etang Z’Abricots Marina
Trade winds from the east over the Bay of Fort-de-France increase agitation at the "Étang Z’Abricots" marina, reducing user comfort and raising maintenance costs for port equipment and vessels. Climate change worsen these problems, increasing the risks of coastline erosion, extreme weather events, and rising sea levels, which may diminish the protective effect of "Pointe des Sables," leaving the marina more exposed to the winds (Ref 1; 2).
The Z’AB project aims to address these challenges by creating a protective barrier for the port by using mangroves. This involves installing lightweight, reversible devices to elevate the sea floor and accumulate sediments, encouraging the natural colonization of mangroves south of Pointe des Sables. Natural colonization refers to the growth of mangroves through processes like seed dispersal and sediment buildup. Once established, the mangrove will act as a natural buffer, protecting the marina from rough seas and adapting to rising sea levels. The project also includes educational efforts to raise awareness about the importance of mangroves for the region’s environmental issues and biodiversity (Ref 1).
Although the Z’AB project has been in planning since 2018, in 2021, a separate project to extend the marina, costing 7 million euros, was approved by the water park authorities (Ref 5). The extension will add 77 new vessel spaces (Ref 7), but it threatens portions of the mangrove and a strictly protected coral species, Oculina Diffusa, found in the area (Ref 6, p.17). While the marina extension project aims to offset the loss of coral and mangrove with various solutions, "Projet Z'AB" is not explicitly mentioned as a compensation mechanism (Ref 6, p.24). However, stakeholders involved in Projet Z'AB are also participating in the development of the marina extension (Ref 6). It remains unclear to what extent Projet Z'AB will be used to mitigate the environmental impact of the extension.

Bangpu Nature Education Center
Due to the decreasing number of mangrove forests in the inner Gulf of Thailand, WWF Thailand aspires to protect the remaining mangroves. Supporting this objective, WWF worked with Royal Thai Army (RTA) and several other partners to establish the Bangpu Nature Education centre. The centre is located on the land of the army, which contains one of the last indigenous mangrove forests in the inner Gulf of Thailand area. The education centre offers knowledge about mangroves, mudflat ecology and biodiversity through educational programs tailored for different visitor groups. Apart from the main visitor center and auditorium, the educational centre also has an outdoor area that includes an existing mangrove forest, salt marshes and mudflats with natural trails, observation towers and canopy walkways. The natural area is home to various native plants and wildlife, especially local and migratory birds. The site harbours 65 floras and 60 benthic faunas, and between 8,000 and 15,000 birds are estimated to use the site annually. Part of the area is an abandoned shrimp farm, waiting for nature to restore

Selangor Maritime Gateway and Klang River Rehabilitation
The rehabilitation of the Klang River or Selangor Maritime Gateway (SMG) is a project that was put into effect in 2018 by the Selangor State Government. The project aimed to transform the Klang River, considered the most polluted river in Malaysia, into a beautiful and clean river which can be a new source of economic growth in the state of Selangor, Malaysia. The river has been polluted with trash, plastic bottles, and sewage, which harmed the vegetation and the aquatic ecosystem (1). The project proved to be highly complex as it included rehabilitation of the river through several green solutions such as the creation of a community park, the conservation of various species of mangroves, and the implementation of riverfront greens as a measure of slope protection. The intervention is set to be developed on an area of 56 Km along the Klang River corridor. It is expected to promote and support the integrated management of river basins with particular emphasis on ensuring that biodiversity and wetland conservation and community considerations are incorporated into river basin management that includes the development of eco-city (3,5,6). Furthermore, the project intends to conduct an awareness campaign about river cleaning and rehabilitation activities to educate the public on the importance of rivers and the environment in our lives while consequently highlighting the critical state of pollution faced by the River (1).
Constructed wetland
In 2005, a constructed wetland was established in Barangay Villareal, Bayawan City in order to improve a peri-urban settlement and promote domestic wastewater treatment with reed beds. The wetland covers an area of 2680 square metres and comprises two reed beds, with the first bed utilizing perforated pipes beneath a sand and gravel substrate for vertical flow filtering, and the second bed utilizing horizontal flow for biological filtering. The roots of the Phragmites karka reeds, which are used in the system, act as a natural filter, removing microorganisms and pollutants. The treated effluent is reused for various purposes, such as watering plants, firefighting, and irrigating ornamental plants and agricultural crops. The overarching objective of the initiative is to safeguard coastal waters from pollution caused by domestic wastewater and enhance residents' quality of life by providing safe sanitation and wastewater treatment facilities. Furthermore, the initiative seeks to showcase the effectiveness of constructed wetlands, encourage the use of locally available reeds for wastewater treatment, and conserve water and nutrients by reusing treated wastewater. [1,2].
