Increased protection against flooding

Isar River had been regulated at the end of the 19th century by forcing the river into a canal-type bed with embankments. This regulation made a negative impact on the flow velocity of the river, on its temperature balance, and increased the risk of flooding. The goal of the recent development was to restore the river's natural character on an 8-kilometre-long section of the river and to create a semi-natural riverside. (Reference 1, 2) This was considered especially important because the effects of climate change have already increased the frequency of heavy rain events and major floods. (Reference 3) The new concept leaves space for the river to shape and change its bed with every flood. Further aims of the project were to increase biodiversity and recreational quality.

Little France Park is the city’s newest park reclaiming unmanaged grassland for the local community and carving out a green corridor from the city centre to Midlothian. It will establish a new corridor for wildlife whilst offering a network of paths, cycleways spread across 45 hectares. ELGT have submitted a Pre Application Notice to create new public parkland. It will establish a new corridor for wildlife whilst offering a network of paths, cycleways spread across 45 hectares. It is expected to provide a valuable green asset to new and existing communities. The parkland will be an important part of the green network with enhanced biodiversity. The existing landscape features will be enhanced, including wetland habitats, woodland planting, meadow grassland and space for events or informal sports. It is an opportunity to create active travel routes integrated with green infrastructure. The fully realized Little France Park will include 3 parkland areas, which together create habitat and species-rich areas. The project is due in late 2020. (ref 1, 2, 5, 6)

Hailes Quarry Park (HQP) is a large open space in the south-west of Edinburgh. It covers an area of 12.15ha. HQP was a very boggy area in the centre of the park which was effectively out of use. A project was planned which aimed to make environmental improvements and engage the local community and encourage healthy living. One of the main features of the park’s recent development is the creation of a wetland area with a range of wetland plant species. This new habitat will be home to birds, amphibians and native wetland plants, and will be a part of the green corridor. Additionally, a Biodiversity enhancement project was carried out at the site (ref 1, 7).

“The Living Environment Trust is an environmental charity based in Coventry, which aims to promote environmental and sustainability awareness within local communities. Accordingly, the Trust uses the restoration of neglected inner-city green spaces as a way to engage a range of community groups, whilst also serving to enhance and expand the existing biodiversity and develop important community and educational resources.” (Ref. 1) “The Living Environment Trust was formed in 2007 to transform the neglected land around the Alan Higgs Centre into a community ecological and leisure resource.” (Ref. 2)

In 2016 the Municipality of Lisbon started the renovation of the Botanical Garden of Lisbon, declared in 2010 as a national heritage monument. The botanical garden is both a vital urban open space and a significant cultural landscape of the city. This Botanical Garden is home to an important collection of plants with economic value, reflecting the strong links to the Portuguese expansion and the routes of the navigators that spread them across the various continents. The intervention is expected to provide improvements in the irrigation and water circulation systems, in the rainwater harvesting system, in the reorganization and improvement of garden green spaces, and in the restoration of paths. With the objective of requalifying the space, bringing significant improvements in terms of sustainability of resources, visitors safety, new cultural and recreational opportunity spaces (Ref. 3, 4, 8).

This area of Keighley is drained by a combined sewer system operated by Yorkshire Water. The natural drainage system is poorly defined.
During extreme rainfall, water from the park and adjacent housing flows down the hill and into the surrounding area and causes flooding. Storage in the form of SuDS was provided in Devonshire Park using a series of “trench trough” structures. These take the form of depressions (swales) with gently sloping sides (ref. 1). Extensive flooding in 2008 and 2012, the local resilience group has been working tirelessly to reduce flooding in Devonshire Park areas (ref 4). Up to £170m of this has been brought forward to accelerate work on ‘shovel-ready’ flood defence schemes to begin construction in 2020 or 2021. The Keighley and Ilkley constituency are one of the beneficiaries, with improvements set to be made to Natural Flood Management aspect of the Leeds Flood Alleviation Scheme, providing an immediate boost to jobs supporting the local economy (ref 4).

A five-year project, would be the largest sustainable water drainage system project to be implemented in Glasgow. The investment follows years of study by the Metropolitan Glasgow Strategic Drainage Partnership, which includes Scottish Water, the Scottish Environment Protection Agency and Glasgow City Council.

Liko-Noe is a business office building that meets all of its energy demands on its own and has a sophisticated system of water reuse and management. The building features a green roof, a green facade, and water storage ponds on the outside (Ref. 1). The building has a constructed treatment wetland for the wastewater treatment, uses solar energy for photovoltaic panels as well as thermal wall (Ref. 4). The aim of the project is to demonstrate that nature-based building techniques can significantly help address the challenges of soil and water degradation, and climate change (Ref. 1).

The Seven Lochs Wetland Park is an urban park that is due to be created in Scotland. It will comprise nearly 20 km² of land and water between Glasgow and Coatbridge. The park will combine many existing features, including four local nature reserves; Bishop Loch, Cardowan Moss, Commonhead Moss (a raised bog) and Hogganfield Park; Drumpellier Country Park which includes Woodend Loch SSSI and Lochend Loch; Frankfield Loch; Johnston Loch; Garnqueen Loch; Provan Hall a 15th-century category A listed building. It will be Scotland's largest urban heritage and nature park. The vision for the Seven Lochs Wetland Park is of a new park of national significance, sustaining and enhancing a high quality, innovative wetland environment that will (a) protect and enhance biodiversity and heritage (b) promote health and well-being (c) contribute to environmental, economic and social regeneration (Ref 1).

The project started in 2013, when a group of private companies started a collaboration with the municipality of Bari to build a series of gardens on the top of households roofs in the city. With a total extension of 2000 sqm for the experiment, the main goal is to create a small micro-climate. The main advantages of this experiment is an improvement in the process of absorption of rain and to reduce energetic costs for heating. The green roofs are expected to play a role in facing the challenges posed by climate change. (Ref.1.)
