Water management (SDG 6)

Haukåsvassdraget is a vulnerable watercourse threatened by urban development and water run-offs from agriculture. The intervention included local use of surface water based on principles such as retention and infiltration, retaining and using the natural watercourses. The plan involved restoring the meandering river courses, ponds and pools and safeguarding the rich biodiversity and the landscape qualities linked to the Haukås watercourse and adjacent marshlands. The Haukås marshland park, combined with modern local handling of surface water, aims to prevent flooding in the development areas at Haukås and to improve the aesthetics of the area. (Ref. 1)

Royal Botanic Garden Edinburgh (RBGE) is endorsing - Edinburgh Adapts - the city’s first climate change adaptation action plan as a demonstration site of the ClimateXChange project. The 2012 persistent heavy raining incident brought flooding and damage to beds, lawns and paths at RBGE. A study is being carried out to see the impact of weather events on their gardens and how this can be used to best deal with projected climate change. Horticulture and visitor services staff at the Royal Botanic Garden Edinburgh (RBGE) and its Regional Gardens are already adapting to climate uncertainty. (ref 2, 3)

The Braid Burn is a highly urbanised watercourse that has been significantly modified to improve drainage. Prior to re-meandering of the Braid burn, it was constrained in a narrow, brick-lined channel with little character, offering a poor habitat and possessing low species diversity. The restoration work reintroduced diversity to allow natural morphological and ecological processes to take place (ref. 2). A new wetland habitat was created, along with a flood storage area. It was a small component of a wider flood alleviation scheme by the City of Edinburgh (ref. 1).

Love Square is a combination of nature and wildlife with a social space for residents and workers. The area has wildflower meadows, lawns and a mini wetland lined with bird-friendly trees (ref 2). Love Square is one of the examples of a new type of ‘smart’ -urban eco-park, combining nature and wildlife with artworks, social and activity spaces. It has a ‘Rain Garden’ and mini wetland that will soak up excess rainwater. It is a prime example of ‘water-sensitive Urban Design (ref1). The rain garden is designed to provide essential urban “greening”; increased soil and vegetation coverage will be able to soak up extra rainfall after a storm, will help to reduce the danger of flash flooding (ref 5).

This intervention is about the restoration of the riverbanks of the Janon River along a street in the Terrenoire District of Saint Etienne. This area was abandoned for more than 10 years, without maintenance and cleaning. Therefore, this intervention was mandatory for clean up to avoid flood as well as bringing back vegetation and offering some quality walking areas for citizens (Ref. 1).

In 2012, the City of Lisbon has implemented a 2,5 km green corridor connecting Monsanto Forest Park ( 900ha) and the city centre through Eduardo VII Park. (1) It is a concept of continuous natural structure, consisting of a coordinated set of green spaces that intend to continuously bring the natural space to the interior of the city (ref.3)
This corridor is a fundamental part of the Ecological Structure, a matrix formed and articulated by systems: the Mobility System, the Water and Air Circulation System, the Fluvial-Estuarine Transition System and the Structural Ecological Units System.

The petrol station is a result of a long-term project of MOL, called as the “The petrol station of the future”. The designers created a building with excellent thermal insulation, green walls, a green roof, solar panels, rainwater utilization and an alternative heating system. Even the interior of the building was created with as much environmentally friendly materials as possible. The building uses LED lighting only to save energy. These environmental efforts resulted in Energy savings of more than 50 percent, and the neutralization of 10 tons of CO2 gas emissions. (Reference 1)

Blackburn Meadows Wastewater Treatment Plant (WWTP) has a mesophilic anaerobic digestion facility, which enables the recycled sludge to be used on neighbouring farmlands as manure. It also enables the generation of renewable energy using combined heat and power units. All the upgrade works were to improve the quality of effluent being discharged into the River Don (ref 3). Sheffield City Council and Yorkshire Water leased an unused part of the former sewage works, to turn into a nature reserve which provides habitat for migrating birds. A water meadow created on vacant land promotes ecological biodiversity and floodwater attenuation (Ref5). In 2013, the works handle a dry weather flow of more than 158,000 cu m of sewage per day, with the treated effluent pumped into the river. It is one of Yorkshire Water’s biggest assets, but with a projected dry weather flow set to hit 368,000 cu m per day by 2025, it is in need of an upgrade (ref 6). The project is fragmented into two phases as the 1st phase was completed in 2013 and the 2nd phase will be completed by 2021 (ref 3).

The University of Sheffield has embraced green roof technology for its benefits to the built environment, and to support Sheffield City Council vision of Sheffield as the UK’s green roof capital. Most buildings the University feature intentionally vegetated green roofs and some existing buildings with suitable structures have been retrofitted with green roofs (ref 1). The first instrumented test plot for the green roof was installed on the Mappin Building roof. In 2009, Jessop West building and the Robert Hadfield – Green Roof Centre Demonstration Site are studied for replicating the model (ref 4).

The areas around MarselisborgCenter in Aarhus get a new and better life. The project will contribute to the world's first city park that handles excess rainwater and invites citizens to health-promoting lifestyles. The area around MarselisborgCenter will be converted into a public city park for both MarselisborgCenter's users (people in rehabilitation) and the citizens of Aarhus in general. At the same time, the area will make the city more robust to future heavy rainfall. (Ref. 1)

The purpose of SPARK is to create a new, vibrant urban space in and around the Marselisborg Center, which partly meets the need for outdoor rehabilitation activities for the center's users, and partly the need for a fully-fledged climate adaptation effort in the area. These needs are united by the construction of a new public park, which also has the potential to increase social inclusion by creating meetings between the users of the Marselisborg Center and the many residents in the district.
