Flood protection

The river Emscher is the symbol of one of the internationally most renowned industrial regions: the Ruhr area with its 5 million inhabitants and an important location of key industries such as steel, chemical, and materials industry. The revitalisation of the Emscher over the last 20 years marks a new phase in the region‘s history and is an impressive example of ecological and socio-economic transformation affecting all aspects of life along the river (Ref. 1).

The aim of the project is to implement a sustainable rainwater management in Hamburg that is adjusted to the heavy rainfalls attributed to global climate change. The project involves the analysis of pilot projects, including GIS-based analysis and the development of the city's rainwater structure plan 2030, Strukturplan Regenwasser 2030, (Reference 1) that will serve as a basis for the Integrated RainWater Management (IRWM) in Hamburg (Reference 5).

EPAEM (Euromediterranean public development establishment) launched the development a new park of 14 hectares. Located in former industrial area at the gates of the northern districts of Marseille, it is considered to be one of the poorest districts in France (Ref. 1). The planned park Aygalades is divided into two parts: the southern part of 4 hectares called Bougainville Park and the northern part of 10 hectares which runs along the Aygalades river (Ref. 1). Development work on Bougainville Park is set to begin in September 2020 with completion in 2023 (Ref. 12). The park is described as "the first step of a large project to restore a highly degraded industrial site" (Ref. 12).

This NBS refers to a curtain protection forest that was planted 6 km out of the city of Iasi in 2015 by the mayor of a commune next to the city. The benefits of this NBS embrace also the city of Iasi as a method to prevent flooding and to avoid strong winds in the area. Afforestation was seen also as a response to the existence of arid soil and abandoned crop fields in the area due to a large population movement of immigration towards Western countries (1)

The Ciric Entertainment Area is a bordering area of ​​the city, located 6 km away from the city center. Before the Second World War Ciric did not exist on the map, being a hollow valley without a forest. Nowadays, being arranged as a recreational site, Lake Ciric is surrounded by a beautiful forest. The rehabilitation aimed at creating easy access to the area, to include it in the functional green area of the city and to increase the quality of life for Iasi's inhabitants (1, 2).

The Grand Park Garonne urban project aims to rehabilitate and develop the banks of the river Garonne that runs 32 kilometers through the city. From 2015, several development projects was planned to be carried out for a total of 28.7 million euros across 3 areas: the Garonne downstream, Toulouse center and the city's "green lung" Island of Ramier (Ref. 1, 4). Within these are 12 sites that consist of 40 pilot projects for operations. Among these are projects focused on protecting and restoring natural habitats and species in order to create a citywide green corridor (Ref. 8).

In 2016 the Environmental Protection Division of Hannover's Department of Environment and Urban Environment started a common pilot project, KlimaWohL, with Bothfelder Kamp GmbH & Co. KG and the Gundlach Group. The building project in Hanover-Bothfeld, formerly called “Hilligenwöhren”, was renamed to “Herzkamp”. By 2021, the family company Gundlach will build approx. 300 terraced houses, rental and freehold apartments. The aim of the project is to implement a new residential area where the researchers of KlimaWohL can systematically test the climate adaptation strategy of Hanover. The new residential area that aims to be an innovative example of climate-adaption for other cities will be equipped with extensive green surfaces and will pay attention to protect the natural environment and species. (Reference 1, 3). In 2018, planting the edge of the forest was started, wherein a tiered 20m wide border consisting of shrubs and trees were planted between the forest and the residential area. Construction of the rental apartments was started and by 2019, the row houses and semi-detached houses have started to be sold. The shell has been completed and the interior work has started. By 2022, overall completion of the project is foreseen.

Andromeda is the first eco-district of Toulouse Métropole. Extended on the municipalities of Blagnac and Beauzelle, it brings together 210 hectares of green spaces, housing estates, residences and corporate offices. The district has been designed around the principles of sustainable development and the preservation of the environment (Ref. 1). The district includes a green corridor network, rainwater management systems (sumps, gutters, recovery tanks, landscaped basins, etc.), 12,000 trees, and the majority of buildings are equipped with green roofs, while green and blue spaces total 70ha and natural areas are 1/3 of the total area (Ref. 2, 3).

The project is the reforestation of the peri-urban parks of the city of Malaga in order to make the city greener while adhering to the dry and hot climactic condition of the region. It consists of phases, where native trees to the region were planted totaling over 50 000 new trees in the city. (ref 1-10)

A major housing development is proposed at Chapelgarth’s 112-acre site as part of a 20-year regeneration programme in Sunderland. The landscape strategy aims to enhance the natural green space and provide parks and green spaces for current and new residents. There will be a green buffer between Weymouth road and the new development which will include drainage ponds for water management. At the heart will be Central Park, defined by the mature trees and hedge grows, which are already in place. A large "Sustainable Alternative Natural Greenspace" will be created and Sustainable Drainage Systems will be installed throughout the neighbourhood (Ref1).
