Environmental regulation

As a consequence of the rehabilitation of a highway that connects Craiova to Bucuresti, the municipality of Craiova implemented ecological parking spaces in the areas that went alongside this road. It was a much-needed solution in a city that lacks in green spaces. The first experimental parking space was implemented in 2008. Most of the parking spaces are located near building blocks (1).

The Restoration of degraded wetlands in Wolfschlugen (in the administrative district of Stuttgart) was conducted within the wider regional level of sustainable urban development to enhance resilience, protect the city from flooding, support sustainable development, and safeguard biodiversity. Ditches and craters line the 700 metres long and 50 - 70 metres wide strip of landscape northeast of the development boundary behind the Wolfschlugen forest cemetery. This is formed by the Riederwiesen, which absorb water to protect the place from flooding. The wetland should protect people at least during a so-called hundred-year flood and at the same time offer animals and plants a habitat. (ref 3, 11)

“The Went Water Vole Project, a two year project working with local people and landowners throughout the River Went catchment to secure the future survival for one of the most significant water vole populations in West Yorkshire. Work also involves carry out habitat restoration and creation schemes across the area to link up isolated water vole colonies and encourage the re-population of some of their old ranges.” (Ref. 1)

A long-awaited flood defence scheme which is designed to protect the city from a repeat of the devastating floods in 2007. "The ambitious project has taken 14 years of planning" and will protect the city's gateway (Westgate). The project manager from EA, said: "The work we're doing on the Ings Beck scheme will mean Wakefield is protected against the kind of flood that only has a one in 100 chance of happening in a year." The scheme involves solving the flooding problem and encourage wildlife habitat. (Ref. 1)

The Green Ventilation Corridors network in Stuttgart, Germany is an implemented nature-based solution coupled with regulatory policies and incentives. Within this initiative, Green ventilation corridors were created to enable fresh air to sweep down from hills surrounding the city (4).

Greened-over urban railway tracks (grass tracks) is a city-wide program in Stuttgart which assumes the construction of tram lines with grassed-over tracks. This applies not only to planning and construction but also long-term maintenance (ref 1).

"Anglers Country Park (and a local nature reserve) is dominated by a lake, surrounded by grassland, woodland and a wetland area." "This originally farmed landscape was dramatically changed when it became one of the deepest opencast mines in Europe, reaching a depth of 250 feet." Restoration work began after the mine closed, creating the country park. (Ref. 1, 2)

Wakefield Council is "responsible for managing over 2650 acres of grass in parks and countryside areas across the Wakefield district (this includes cutting the grass)". Since 2015, there are small areas where "the grass is being left to grow" naturally for environmental benefits. (Ref. 1) The objective of the project by leaving derelict some grass areas are that "the environmental benefits of leaving some grass to grow naturally include encouraging wild flowers to grow which will support bees and other insects, and aiding drainage to reduce flood risk" (Ref 1).

Due to the challenges caused by climate change, Hamburg decided to become greener and developed a comprehensive, pioneering green roof strategy. The strategy aims at creating 100 hectares of new green walls by 2019 by providing grants for building owners for greening roofs and offering them rain water fee reduction owing to the rain water retention of the green roofs. (Reference 1) The financial support offered until the end of 2019 is 3 million EUR. (Reference 2) The services offered by the city in this plan consist of four pillars: promotion (financial incentive), dialogue, regulation, and scientific support. (Reference 7)

With the relocation of the railways between the Hauptbahnhof and Pasing a large area became available for an infill development strategy. The redevelopment of central railway areas of Munich is in line with the city's guidelines for sustainable development (Perspective München) referred to as compact - urban - green. The initiative is aimed at implementing 7500 new flats and creating 15000 new workplaces in total, which are supported by green recreational areas. (Reference 1) The project consists of six separately planned parts, some are already partially finished. (Reference 2) This NBS discusses Birketweg, one of these parts, which is 60 hectares large.
