Bayou La Batre, also known as the seafood capital of Alabama, has been facing severe flooding problems, including the occurence of combined sewerage overflows. The Nature Conservancy has secured funding to install a green stormwater project in Bayou La Batre, adjacent to the library, sports fields and the community center. Alongside the aim of the green stormwater project to decrease flooding events in the community by infiltrating water, it also serves as an education and engagement project [1]

To reduce the risk of urban flooding, the city of Seville, through its metropolitan water company Emasesa, established several "sustainable urban drainage systems". One of the pilot locations is on the Avenida de las Ascociaciones de Vecinos, where a rain garden complemented by an infiltration zone was established. The main aim of the project is to reduce the risk of flooding, but the system can also improve the urban landscape by offering green space, preventing desertification and reducing pollutants carried by runoff [Ref. 1-4]. After implementation, the project was shown to be effective during heavy rain [Ref. 5]. The system can store up to 34 m2 of water and reduce flow rates to the sewage network by 69 % and the total runoff to sewage by 93 % [Ref. 3-5]. The project was initiated and led by Emamesa, while two different companies were employed to design and construct the system [Ref. 1, 2, 6, 7]. The total budget of the project, which also included some renovations of grey infrastructure along the street, was 165000 EUR [Ref. 1].

Assemini, a municipality in Cagliari, has long grappled with hydrogeological instability, marked by major floods in 1999 and 2002. To mitigate future risks, the municipality launched a series of interventions focused on improving the hydraulic management of its waterways. These projects are part of a broader strategy to address recurring flood hazards exacerbated by the effects of rapid urbanization in the 1970s, which disrupted the natural water drainage systems (1,3). The central goal of the project is to reduce the risk of flooding by enhancing the functionality of existing waterways. This includes both preventative measures and structural improvements to the canal system to manage stormwater more effectively. These efforts aim to safeguard urban and rural areas from severe meteorological events. The project development involved a multi-phased approach starting in 2013, focusing on cleaning and maintaining minor waterways such as the Gutturu Lorenzu, Sa Nuxedda, and Giaccu Meloni streams. These efforts expanded over time, culminating in an agreement with the Land Reclamation Consortium of Southern Sardinia in 2015, securing both local and regional financial support. The interventions have covered over 24 kilometers of canals and streams, targeting key flood-prone areas (1,2).
Key interventions include the cleaning and maintenance of over 35 km of canals and streams, in partnership with the Land Reclamation Consortium of Southern Sardinia, supported by regional funding. A separate, large-scale intervention in Truncu Is Follas involves constructing an open-air diversion canal, a retention basin (44,500 m³), and new pipelines to redirect floodwaters, thus reducing risk for residents downstream in both Assemini and Elmas.

This project aims to increase water retention capacity in the landscape around urban areas and promote biodiversity by restoring wetlands and natural streams in the forested areas on the island of Hisingen in northern Gothenburg. Many wetlands and streams in the area have been drained or otherwise affected by human activity, reducing biodiversity, increasing the risk of floods and droughts and causing greenhouse gas emissions from peatland. The goals of the project are to reduce the risk of floods downstream, reduce the effects of dry periods, increase groundwater infiltration and benefit species living in and around wetlands and streams in the forest [Ref. 1-3]. The Swedish Anglers Association has initiated the project in cooperation with the City of Gothenburg and the environmental engineering company Miljöteknik I Väst AB [Ref 1]. The project's first stage is a continuation of an earlier project to make an inventory of wetlands and their status [Ref 1, 2]. For the second part, 6,9 ha of wetlands and streams on land owned by the city were restored [Ref. 1, 3]. The project will lead to further efforts in wetland restoration around Gothenburg [Ref. 2, 4].

This series of projects in the Trinity Garden aims to improve sports fields, enhance drainage, and replace HVAC (Heating, Ventilation, and Air Conditioning) systems at the community center in the Trinity Garden community (Ref 1). The first project involves a complete renovation of the playground area at Trinity Gardens Park. The entire playground will be rebuilt with a new drainage system, along with the installation of a new play structure, benches, and trash receptacles (Ref 2). Another key component of the project includes the construction of a new natural baseball/football combo field, with a new infield, bases, outfield fencing, foul poles, and with improved drainage (drain piping, inlets, sodding, and irrigation) for the sports field (Ref 3). On the subject of recreation and public health, Councilman Fred Richardson emphasised the significance of Trinity Park, stating, “Good public parks are key to creating healthy children and, in turn, strong communities. I am so happy that we are able to bring these major improvements so local children will have a great place to come play, and their caregivers will have a place to watch them from” (Ref 2).
Additionally, another major project on the agenda focuses on street and drainage improvements within the community. This will address issues on Warsaw Avenue and Collins Avenue, from Main Street to Jessie Street, aiming to resolve several hazardous open ditches that currently run through the neighborhood (Ref 2).

The project for Tricentennial Park involves a series of improvements aimed at enhancing its overall infrastructure and appeal. Among the planned upgrades is an enhancement of the pavilion, along with the addition of other site amenities (Ref 1). A lake is also being created as part of the project (Ref 2). Currently, work is underway on phase two, which includes landscaping, the construction of a group picnic pavilion, walking trails, a parking area, and even a misting machine to provide relief during hot weather (Ref 2).
One of the key highlights of the project is the opening of a new playground in 2024, featuring a unique design. The park is laid out in a figure-eight pattern, and a sign within the park highlights its recognition for following “best practices in youth fitness,” encouraging children to stay active through sliding, swinging, spinning, climbing, brachiating, and balancing (Ref 2). This park is the first in Mobile designed exclusively for passive use, without ball fields, providing a space for families and individuals to enjoy the playgrounds (Ref 4). The park fosters social interaction, allowing children to build friendships and create lasting memories while spending time with their families (Ref 4). The park also boasts beautiful scenery, adding an aesthetic dimension to the overall experience (Ref 2).
Tricentennial Park is part of the larger Three Mile Green Trail, a 6.5-mile linear park. A one-mile segment of the trail is located within Tricentennial Park. The trail will be expanded east to MLK Boulevard and west to Bush Park by 2024 (Ref 1).

The Torre Sevilla is a commercial building complex with extensive green roofs. The green roofs cover 11000 or 12000 m2 (different sources report different numbers) and aim to contribute to thermal isolation and energy efficiency of the building, improve air quality and provide an urban green space for relaxation and recreation [Ref. 1-3]. The green roofs include a mosaic of different vegetation types and about 60 mostly native plant species. There is a rainwater recovery system that allows the gardens to be irrigated in a sustainable way [Ref. 1-3, 6]. The building finished construction in 2017 and the gardens were initially not available to the public. In 2023, the owner applied for a permit to host events in the gardens, which will allow the public to visit on occasion [Ref. 1, 3-5].

In Sjöhåla, west of Kungälv, an abandoned pasture on a wet meadow by the coast was restored by reintroducing grazing, clearing bushes and reeds, digging ponds and renovating stone walls. The aim was to increase biodiversity in the area and to promote the production of local organic meat. Additionally, the project made it easier for visitors to pass through the area for recreational purposes. The project was carried out by the municipality of Kungälv and the non-profit organisation Omställning Kungälv, and involved other local associations, farmers and citizens. It was funded through the "Local nature conservation investment" by the Swedish Environmental Protection Agency. As a result of the project, the area is more accessible, and many species of plants, insects, and birds have been found. [Ref. 1-3]

Perch Creek is one of the many meanders that drain into Dog River (Ref 2), located just west of Mobile Bay (Ref 3). These areas include sensitive, tidally influenced marshes and flats where the brackish water of the Bay meets fresh waters (Ref 1). The Perch Creek Nature Trail & Preserve project aims to protect 96 acres on Perch Creek (Ref 3). It is part of efforts to revitalise Mobile’s coastal community and improve the water quality of the city's urban river (Ref 2), following the devastation of the BP oil disaster in 2010.
The project focuses on two main aspects: creating a low-impact recreational destination to spark economic redevelopment, and preserving Mobile’s coastal wetlands (Ref 1).
The conservation aspect involves wetland acquisition, marsh restoration, and invasive species management, improving water quality in both waterbodies (Ref 1). The area, rich in wildlife, requires habitat protection, including for migrating birds, foxes, alligators, manatees, and bald eagles (Ref 1). Brackish marshes on the property serve as nurseries for fish, while forested areas provide natural corridors for wildlife (Ref 3). The wetlands also play a role in flood control, acting as natural sponges to absorb rising tides and cleanse stormwater runoff before it reaches Mobile Bay (Ref 1). Additionally, they store stormwater, helping mitigate flooding as storms intensify (Ref 3).
The recreational aspect includes developing nature-based recreation, such as nature trails and kayak launches, as well as expanding public access to natural resources (Ref 3). In 2018, the Perch Creek section was added to the Alabama Coastal Birding Trail, with educational signage for kayakers (Ref 1).
This comprehensive project preserves vital habitats and flood-absorbing wetlands, while providing outdoor recreation opportunities and supporting the coastal community's recovery (Ref 2). It combines high-quality water resources, wildlife connectivity, scenic beauty, and outdoor recreation (Ref 3).

Located in the Lima district of San Isidro - the heart of commercial activity in Peru - the Real Dos Tower is a prime office building in the Centro Empresarial Real de San Isidro. It was inaugurated in 2018, and it is distributed over 23 levels (14 floors and 9 basements) and enjoys a landscaped green roof (1162 m2) at the crown of the building and numerous outdoor vertical gardens at full height (2365 m2) on the three main fronts (1, 4). This project was a finalist in the 2018 Mipim Awards, considered the ‘Oscars’ of world architecture, and stood out for its architecture and design, due to its attributes of innovation and sustainability (2).
This building has managed to create harmony between design and efficient use of resources. It is characterised by a glass façade with colourful movable shutters and symbolic Peruvian designs (2, 3, 6). It has green walls on the three main fronts, four daylight fronts and a roof garden (2). The architect, Jean Nouvel, worked together with ARVE Peru on the overall landscape plans for the Real Dos tower (1, 3).
This is part of the façade remodelling project of the Camino Real Towers in the Real Business Centre, led by the real estate company Grupo Centenario (1, 2, 3, 4, 5, 6). This overarching Project has sought to develop 4,475 m2 of vertical gardens and roof gardens, which have a technified irrigation system to generate efficiencies in water use, meeting the plants' water requirements in the different seasons of the year. Their implementation helps to filter CO2 and renew the O2 in the office complex.
The ARVE group describes these actions as conducive to creating thermal barriers and sound insulation, a better environment for rest, work and entertainment and increasing property value (7)
