Coastal resilience and marine protection (SDG 14)

Larkhill Gardens Lake improvement is a collaborative project between the City Council, the Environment Agency and the local community. It is part of the long-term project, Liverpool Park Lakes Project, whose aim is to tackle many problems faced by shallow park lakes. Larkhill Gardens Lake (4936m2) a circular shaped, steep, vertical hard-banked lake, situated in a small estates garden in the city. Like many lakes, Larkhill Gardens Lake experienced problems linked to structural decline, lack of water, poor water quality, poor habitat quality, loss of management of the user and lack of proactive management by the City Council. The improvement of the lake included changing its structure to create a deep-water fishing area, shallow water area and wetland.
The project was funded by a partnership between Liverpool City Council and the Environment Agency (Reference 1).

“Xarxa de Sendes Urbanes de Alacant(Catalan)/Red de senderos urbanos (Spanish)” (Red of Urban Trails) is a network project developed by the city council consisting of urban trails classified into three types: environmental or natural trails, cultural or heritage trails and city trails, the latter as network connectors. The NBS focus on the first type (environmental and natural trails). (Ref 1) With the implementation of interconnected trails system and signage, the trails offer walks, educative explanation on the different species found in the area and provide leisure, relaxing and physical (running, hiking) opportunities to visitors and citizens. (Ref 2)

The initiative is comprised of a project to recover the coastal line of Alicante, from El Campello to Elx (approx. 21 km long). The Municipality called an ideas' competition with the aim of developing a sustainable coastal corridor project that includes an intervention on the entire Alicante coastline and generates a continuous itinerary integrated into the landscape with new places of opportunity for the residents of the city (Ref. 7). The two-stage competition sought proposals for a new ‘coastal passage’ featuring the creation of new multi-purpose public spaces promoting biodiversity and accessibility (Ref 13). The winner was announced on the beginning of 2019 and the Municipality planned to start the development of the first 2 parts of the project. The winning project of the competition bears the slogan "My connected archipelago" and is the work of the Grupo Aranea and Subarquitectura studios from Alicante (Ref 14), a project that considers ecological and sustainable principles (Ref. 9).

The Port of Alicante is finalizing the installation of a new environmental barrier at Pier 17, where bulk unloading is carried out, based on a water atomization method that allows dust particles to fall to the ground of the port area and not arrive by air to the city. (Ref 11) This initiative comprises activities to reduce pollution in the port, such as a vegetable barrier against the air pollution produced by the dust during the unloading of bulk materials, supplied by an irrigation system that recovers non-drinkable water from a nearby plant. It includes the extension of the Parque del Mar, to recover historical points for tourism and the funding of a research project on air pollution (Ref. 12). “This measure is integrated within the Plan of Urban Integration of the Port of Alicante, improving the landscape impact and the port-city boundary zones from the southern access of the urban environment, along with the “Parque del Mar”, to the west zone with the installation of vegetal screens in the inner zone of the port, contributing to an important particle retention and CO2 reduction.” (Ref. 1). Inside the park, which can be traversed through paths, there is a small ornamental lake with rockery and it has children's games and petanque courts, gymnastics courts and recreational areas. The green corridor has been created with the creation of artificial mounds, for which 65,000 cubic meters of earth have been necessary, which act as a vegetal screen and visually and acoustically isolate the port facilities of the city. (Ref 7)

The Venice Lagoon is characterised by intensive agriculture and by a web of drainage channels discharging into the rivers. The Veneto Region, through the “Plan for diffuse pollution prevention and restoration of water in the draining basins of the Venice Lagoon” financed measures of re-calibration of riverbeds aimed at the renaturation of the hydraulic web, to increase the time of permanence of water and phytodepuration processes in the draining basin. This case study, in particular, includes measures on the drainage channels discharging into the Dese river, one of the main water bodies of the Venice Lagoon basin. In particular, it aimed at re-structuring the effluents of the mid-course of the Dese river (Rio S. Martino, Rio S. Ambrogio and Scolo Desolino). (1).

The project LIFE SeResto (LIFE12 NAT/IT/000331) aimed to trigger a process of aquatic recolonisation in “Northern Lagoon of Venice”, mainly through the transplantation of "Zostera marina" and "Zostera noltei" to small sites distributed throughout the area. The proposed intervention technique involved transplanting a small number of plants, with advantages in terms of lower costs and impact on the donor sites (1).

Bundek Park is one of the urban planning projects aimed to create a recreational and sports area for the citizens and tourists to support a healthy lifestyle (Ref 3). The lake is surrounded by Bundek Park which stretches for 2,000 meters in length with an area of 35 hectares. The lake is about 5 hectares. the lake was initially used for fishing, walking and swimming. With the increased and carefree use of the lake, the lake and the environment became a waste disposal site. In 2005, by the decision of the Mayor, Mr. Milan Bandić, the renovation of Bundek began. The project included cleaning of the informal waste disposal site and shrubs blocking access to the lakes, renovation of the access to the lakes, planting flowers and introduction of the benches and water also to allow citizens to use the lake for recreation and enjoy the nature (Ref 2).

‘Slussen and a new water regulation plan for Lake Mälaren’ is part of the rebuilding of the city district Slussen (The Slussen Project) (Ref. 1). In connection with the rebuilding of Slussen, SMHI (Swedish Meteorological and Hydrological Institute) was in 2007 commissioned by Stockholm City to review and propose a new regulatory strategy for the lake Mälaren (Ref. 2). A new regulation prevents floods, reducing the risk of saltwater entering the lake, benefiting the natural environment around Mälaren. Further effects will also benefit the ecosystem of the lake (Ref. 3).
