Strengthened capacity to address climate hazards/natural disasters

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.

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).

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).

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).

Trees and a park have been created and designed for the double building project called CEMAGREF/ENGREF in Clermont-Ferrand which was planned in 1994 (Ref. 2 and 4). CEMAGREF (Center for the Study of Agricultural Mechanization of Agricultural Engineering of Water and Forests) and ENGREF (National School of Agricultural Engineering of Water and Forests) are located within the IRSTEA (National Science and Technology Research Institute for Environment and Agriculture) (Ref. 3).

The Forest of Belfast is an imaginative label for urban tree initiative launched in the 1990s with the aim of conserving and managing existing trees, increasing the planting of suitable trees, particularly in places of public access like parks, and in promoting an interest in and an appreciation of trees and forestry(Ref 3). The project was officially launched in June 1992 (Ref 1). It is active throughout the urban area of Greater Belfast, including Belfast City. It brings together partners from the statutory sector, voluntary groups, businesses, and individual residents who become volunteer Tree Wardens. It shows how urban forestry can forge partnerships between central and local government, environmental organizations and city dwellers. (Ref 1). Forest of Belfast initiative was wound up towards the end of 2010 (Ref 6).

Győr and its surroundings boast many rivers, streams and lakes, and experiences intense flooding almost every year. The main goal of Nagy-Pándzsa project was to reduce the risk of flood and to regenerate the Nature 2000 area (Reference 7). Due to the reconstruction of the water transporting feature and the reconstruction of the flood-gate, the flood protection could improve and the pollution of waters could decrease. Therefore, the conditions of flora and fauna of waters improved and the size of the utilizable area increased (Reference 8).

Situated in park Spilberk, the garden features a building with a green roof and a garden with various plots. The building is designed to be carbon neutral and reuses rainwater for toilet flushing and for watering the garden plots. The garden is used for horticultural purposes and environmental education, as well as animal and beekeeping. The complex improves the local micro-climate through cooling and humidification and promotes biodiversity. (Ref. 1; Ref. 2; Ref. 5; Ref. 6)

This project worked to revitalize the area along the river Old Ponávka. This involves the creation of walking paths, bike paths, and public playgrounds. (Ref. 1). Stará Ponávka and the adjoining Svitavy drive were built in the 13th century in the original riverbeds of Ponávka and Svitava before their regulation. By revitalizing this watercourse, the city returned water back to the city, made it accessible to people and improved the natural state of the site (Ref. 14).

The Water of Leith is home to a wide diversity of plants and animals. The river performs an important flood control function in the city. A management plan envisions to create a healthy river that flows through a green corridor from the hills to the sea and is a haven for wildlife, is enjoyed and managed by the public, and is valued for its built and cultural heritage. The current intervention is about an extensive Flood Prevention Scheme. Walls and other flood defence measures have been constructed from Murrayfield downstream to Bonnington. A re-modelling exercise is being carried out to include the impact of climate change on the river system and the efficacy of the flood prevention scheme. The Water of Leith Conservation Trust works to conserve and enhance the river, its heritage and wildlife. It also promotes education and recreation and works with volunteers and community groups (ref 1, 2, 3).
