Public regional budget

In 2015, 20,000 British Pounds have been raised to help wildlife in the Elba Park in Sunderland. The funding was granted to create new habitat for priority species in Shiney Row in Elba park. Community groups and schools were one of the major parts of the project. People were engaged to enhance their learning experience. This project was partly crowd-funded (Ref 1).

The renaturalization of streams is a common strategy for improving the ecological quality of water bodies as mandated by the European Water Directive. For that reason, parts of the Aa stream in Münster upstream until its flow into the Aa lake covering 2.6 km were renaturalized from 2012 to 2013. Renaturalization is a means to restore the natural river banks, local ecosystems of the Aa rive and improve the water quality of the Aa lake (Ref. 1 and 3).

Grangetown is the site for a flagship environmental programme to tackle flood risk and water waste (ref 5). This scheme catches, cleans and diverts rainwater directly into the River Taff instead of pumping it over 8 kilometres to the sea. It will make Grangetown a greener, cleaner place and enhance local biodiversity (ref 2). Every year more than 40,000m³ of rainwater is diverted from entering the combined sewer network (ref 1). Interventions include planters, swales, bio-retention ponds, permeable paving and curb drainage, making use of the existing streetscape. 108 rain gardens have been created, and 130 trees have been planted; the area has been deemed the 1st "bicycle street" in Wales (ref 8). Wider benefits include education, health, well-being (ref 1).

Forests fulfil several important climate functions, they are carbon sinks, regulate the local climate or buffer heatwaves and cloudbursts. Based on climate projections, longer dry periods are to be expected during summer months which have major implications for local humid forests. The “fit for climate change” project was initiated to develop and implement climate adaptation measures for the latter, for instance via hydrological regulation, the use and reinstatement of resilient, adapted tree species or revitalizing moors and swamps. It was administered by the regional forestry authority and the nature conservation station Münster (Ref. 1 and 2).

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 Aa promenade, created in 1950 to provide the citizens of Muenster with a green experience trail in the inner city, was redeveloped in the 90s with several planting measures on riverbanks, walls and in adjacent areas. Next to a brochure, a nature trail which combines the existing recreational with an educational component was created with 18 site-specific signposting points. They cover multiple benefits and ecological functions of urban green spaces, city trees and green facades/walls (microclimate regulation, air quality, CO2 capture), anthropogenic threats, unknown biodiversity hotspots and natural monuments (Ref. 1, 3 and 6).

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).

The Park Killesberg serves as the green centre of the newly constructed district in Stuttgart and continues the long history of the area as a garden show site with a contemporary expression of landscape architecture and as a model for interconnected green spaces. The design is the result of a collaborative process with the local authorities, citizens and neighbours (1).

The construction of a new main bus station inaugurated in 2014, is part of a desire to reduce greenhouse gas emissions and to encourage users to favor bus routes (Ref. 1). Part of this construction project, a vegetal wall of 210 meters long and 8 meters high has been implemented in order to act on noise (-20 decibels) and visual pollution, and improve air quality. It will be the largest public vegetal wall in France. (Ref. 4, page 26)

After its abandonment by the British military in 2012, the development of a new utilization concept and plan for the former military base in Gremmendorf was encouraged by the city’s planning department. Intensive citizen participation efforts were identified and ideas conceptualized, followed by an architectural competition based on which the spatial development plan was elaborated. The plan, which is currently being developed further by the winning architecture bureaus in coordination with the spatial development authority, intends the development of an attractive living quarter as a "garden town" with several green and sustainable drainage elements (Ref. 1 and 5).
