City specific climate change policy or plan

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).

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).

After being abandoned for more than 10 years following the collapse of a building, a piece of land inside the city's "Le Panier" district was approved by the city in 2017 to become a "neighborhood garden" combining green space and a community vegetable garden (Ref. 1). After many delays the project was completed in early 2020 and the garden opened on February 28, 2020 (Ref. 11). The district "Le Panier" (where this intervention occurs) attracts many tourists every year for the charm of its narrow streets and colorful facades (Ref. 1).

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.

The City of Marseille has three pedagogical farms which are intended to raise awareness of nature and encourage citizens to "discover to love and respect the environment; Study and experiment to act responsibly" (Ref. 1). "Among the various awareness-raising and environmental education tools developed by the City of Marseilles, pedagogical farms are the most concrete way to re-establish contact between urban youth and the rural world" (Ref. 1). The "Collet des Comtes" is one such farm and its "three hectares of land are occupied by open-field and greenhouse crops, grazing areas, an orchard, a pond and a pedagogical garden" (Ref. 1). The farm hosts educational events for children and organic markets (Ref. 5,6).

The planned intervention focuses on creating accessible green spaces for meaningful social exchanges. The City Council seeks to achieve this through a ground plan of connecting green spaces and ease of access into buildings. The intervention, proposed as a lineal green area, centers its structural organization around green spaces and public spaces. Accessibility for pedestrians is facilitated through spines of green spaces that cross the planned neighbourhood horizontally and vertically. These green spaces are planned to be watered with collected rain water, consequently the smart use of water is also a focus of the intervention. (ref 1)

Since October 2015, the City of Marseille has implemented a vegetation permit called "Visa Vert" (Green Visa), as well as a "Charter for the vegetation of public spaces in Marseille", which allow individuals to install plants in public spaces
while respecting the safety and use of the tracks by other users. Plants, flowers and shrubs can thus contribute to the beautification of the living environment and "bring a bit of nature into the city" (Ref. 1). The charter aims to “ accompany and support initiatives to revegetate the streets and promote collective actions that contribute to embellishing the living environment ”, but also to “ enhance the presence of plants in the city, to respect the public space which belongs to all and thus to improve living together ” (Ref. 5).

The Werd Administration Centre contains a green park that provides a good variety of trees with an aesthetic view of the city. Ornamental cherry trees create a lively atmosphere, in the spring with their double-blossom flowers, and in the autumn as their canopy changes colour. This park has been renovated a few years back to increase habitat diversity. The building itself got another renovation in 2014. (Ref 1)

The Urban Environment Observatory Building (OMAU) was built in Malaga as part of the URB-AL 1998 project, it is a construction planned for environmental conservation and includes an ecological cover for the use of rain water in the supply to the structure's watering system. (Ref 2, 3)
