Improved water quality

A new lake with green banks was built in the district of Altenhof in Essen in order to improve the quality of life in the neighborhood, create new recreational facilities and prolong the existing transport and green infrastructural developments in Essen. The water is supplied to the lake by means of groundwater from a separate well, as well as rainwater from the surfaces of neighboring roofs (Ref. 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 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)

In 2012 Marks & Spencers funded a volunteering initiative, the Big Beach Clean-up, through which their staff were able to volunteer to clean local beaches and waterways to make local environmental improvements. This initiative is part of M&S’ Forever Fish campaign which is funded by the profits from the 5p carrier bag charge in M&S foodhalls. The 4th annual Big Beach Clean Up (which took place in 2015) aimed to clean 135 beaches and canals up and down the country with over 8,000 people (3,000 M&S employees and 5,000 M&S customers) (ref. 5). As part of this initiative, around 30 members of staff from Nottingham’s local high street store went down to the canal, between Castle Meadow retail park and Meadow Lane Lock, and spent the day removing masses of litter from the water (ref. 3).

The biotope Schladitz is the regenerated remains of a former installation for the dehydration of sewage sludge implemented in 1952 by the communal waterworks company which used to pump its sewage sludge into the municipality of Rackwitz North of Leipzig. Upon its termination (1990), the company conducted large regeneration works of the contaminated sites from 1991 until 2011. The area was renaturalized, a biotope was implemented with plants species to retain the toxic substances. Now the area is also used for nature experience, observation and environmental education for children and adults (4, 7).

The Bahlui river was prone to floods especially during spring and autumn and as a result of the fact that for almost 40 years there has been no work for the decolouration and sanitation of the river and the industrial enterprises in the county have discharged polluting substances in water (mainly nitrogen and phosphates), Bahlu River has become a polluted river. In addition, some citizens of Iaşi have discarded waste in its bed (especially in peripheral areas). In 2011, a larger project funded by the EU, implemented the regularization of the river. (1)

Numerous developments have been carried out at the National Veterinary School of Toulouse's (ENVT) green campus to make the site more conducive to the maintenance and development of biodiversity as result of the school's "VERT VET" (GREEN VET) club (Ref. 2). The green changes began as a result of the school's 2008 sustainable development policy (Ref. 1). Among its many functions and activities, the policy helped raise awareness, clean ponds, and a well, construct a vegetable garden and make beehives and bird nest boxes in the campus's two classified forests (Ref. 3).

The Rohrschollen island, located near Strasbourg, is representative of a particular environment in Europe: the Rhine alluvial forests. These forests are known for the exuberance of their vegetation and their richness of species: it is a rare ecosystem both at the national and European level. These forests are regressing nowadays and as a result, the four major European rivers from the Alpine range (Rhine, Rhone, Danube, Po) have lost most of their riparian forests. The objective of the project is to restore a dynamic flood regime on the island of Rohrschollen that is modeled on the Rhine's hydrological rhythm (Ref. 1).

The project of Nature Oasis Auwiesen is creating new habitats for animals and plants in Stuttgart. The project is one of a total of six “Neckar pearls” that are to be completed by 2022 as part of the Neckar Landscape Park master plan in Stuttgart. In the project with a predominantly ecological focus, grassland in the Neckaraue near the Aubrücke is to be transformed into a near‐natural, ecologically valuable wetland biotope. In the course of straightening the Neckar, the wet and floodplain biotopes that were typical and widespread in the floodplains have been lost. The aim of the project is to restore these habitats for animals and plants, which have become very rare today. A network of marshes, water surfaces, islands, and bushes is to be created in the district of Hofen. On an area previously used as grassland, new habitats will be created for rare animals and plants, which are dependent on water areas. Initially, the planned implementation time was 2016-2022, but now it has been delayed and is expected to start by the end of 2021. (2, 7).

On November 5, 2019, the Committee for Urban Development and Technology passed the building decision for the riverside park Austraße - Neckarterrassen. To the north of Münster, the Neckar has cut deeply into the shell limestone and describes a wide arc on the Prallufer. There is little space between the cliff and the river - that is what makes this place so special. This is where the Austraße riverside park is being built with the elements Freienstein water playground (element 1), Neckarterrassen and Tapach-Link (element 2) as well as Austraße, Neckarufer and Neckarstrand (element 3). The first component has already been implemented: children will find their favorite spot on the Freienstein water playground south of the Max-Eyth-Steg. Students from the Elise von König School in Münster contributed their ideas as part of a child participation program. With the second component and its sub-projects “Tapach-Link” and “Neckarterrassen”, there are beautiful prospects for Münster: Those who have overcome the relay to the Neckarterrassen can rest in the shade and let their eyes wander up and down the Neckar. The third component of the Austraße riverside park - in addition to the Freienstein water playground, Neckarterrassen and Tapach-Link - focuses on the banks: podiums and platforms are planned on the river to linger while the freighters transport their goods on the water. Insects, small crabs and small fish find optimal living conditions on the renatured bank zones with stones and diverse flora. (1, 7).
