Achieved impacts

A digital tree path was launched in Nancy in 2011. This is a path linking 24 trees equipped with QR codes (Quick Response Codes) throughout the city in order to discover them and their richness by scanning the code with a smartphone (Ref. 2). Information on the trees is also available online through the city's website as well as an Instagram account (Ref. 6).

This audit, consisting of two parts, maps all green spaces in the Doncaster borough and presents an analysis of the quality and quantity of these areas as subdivided into 88 communities in Doncaster. It aims to better understand the multi-functionality of these spaces as well as what are the leverage points to improve their quality.
The first part of the audit contributes toward the evidence base required for the Local Development Framework (LDF) Sites and Policies Development Plan Document. It will also be a useful reference document complementing Core Strategy policy (CS17) providing green infrastructure. Part two of the green space audit investigated the quality and value of the sites. It allows the council to identify priority green spaces, ascertain their formal and informal intended use and allow the council to make strategic decisions on priorities and long term management. It also looks at community profile areas where provision exceeds the defined standards and investigates if green spaces in these areas are surplus to requirement. (Ref 1 & 5).

Bercsényi grove, a large public park, was rehabilitated and functionally extended as part of the socially sensitive urban regeneration project of Győr-Újváros, a stigmatized, relatively underdeveloped area (Ref. 1, 3). The area of the park is divided into three main parts, 1. a recreational park including playgrounds, 2. a sports park and 3. a "traffic park" where children can learn interactively learn the rules of the road in a playful way. Although the project was mainly aimed at creating a place for active recreation, the intervention included the rehabilitation of the green areas and the plantation of several tree lines (Ref. 4). As a result, the area could become a popular meeting point for different generations.

The North Green Belt was developed and built up in connection to investments and structures for the 2008 Expo. (Ref. 1,2) The North Green Belt is a series of connections extending the green corridor and network of green spaces in Zaragoza, with the Ebro and Gallego rivers as the two main axes of the belt. (Ref. 1,2)

The project involves building two green roofs on saunas in Water Park ‘Termy Maltanskie’ in Poznan. The roofs serve multiple purposes including rainwater retention, thermal insulation, habitat for insects, improvement of the air quality by the production of oxygen and absorption of CO2, and aesthetic functions for the visitors to the amenities [1,2,3].

Püspökerdő is a 250-hectare large forest in Győr, situated in the inner part of the city. The forest is split into two parts by Moson-Danube river. The forest is maintained by the company Kisalföld Erőgazdálkodási Zrt, which since 1998, has added new facilities to the area with the primary goal of serving the needs of those who visit the forest (Reference 1). It is equipped with educational trails, fireplaces, a clearing suitable for playing ball games, an outside gym and a playground. The educational trails give information about the flora and fauna of the forest in their natural environment. In 2013, a new adventure park was established to attract the nature-lover visitors looking for active recreational opportunities. In 2017, the local government planned a large-scale watersports project in the area, but it was cancelled due to criticism from citizens. In 2020, the forest was granted environmental protection by the local municipality (Reference 9).
Step by step the area has been developed since 1998, with the help of municipal and regional funds (educational trails), and private investment (adventure park). The adventure park was opened in 2013 and the latest development happened there in 2016.

The Schwanheimer dune is one of the few inland dunes in Europe. Sand, silver grass and gnarled pines shape the landscape, but also orchards and ponds are part of it (8). The area was designated as a nature reserve by the State of Hesse in 1984. Since its expansion in 2002, it now covers 58.5 hectares. Since 2003 it has also been protected as a Flora-Fauna Habitat area under European law contributing to the Natura2000 landscape (8). An approximately 400-meter-long boardwalk made of chestnut wood leads through the center of the dune on which visitors can enjoy nature on site - without harming it (8, 10). It was built in 1999 and completely rebuilt in 2017 with a lot of effort on the old route (8).

"The Imperial Canal of Aragon acts like a green corridor crossing the city of Zaragoza from Montecanal to Torrero and passing through Casablanca and the Great Park." (Ref 2) The more than 200 years old waterway runs through 7 regional parks and green areas and it is 41 km long. (Ref. 1 and Ref 3) Its rehabilitation has been planned in 2003 for parts of the canal with bike paths built, pedestrian walkways, strengthening of its hydrological structure, and protection of its greenery. (Ref 6)

The once rich in fish Nidda river in the north of Frankfurt was canalized and dammed in the 20th century. River loops were pierced, filled in or made into oxbow lakes. Newly built weirs stopped the fish migration. The expansion provided good protection against flooding, but the river became a canal (2).
In the 1990s, the Nidda neighbours developed a program for the renaturation of the river, the concept "Natural Nidda". It was decided by the city council of Frankfurt am Main in 1998 (2). The project consisted of many measures aiming at the restoration of the natural course and ecosystem of the Nidda river, the creation new habitats for flora and fauna, the expansion of the floodplain area and thus the river's retention capacity, the deconstruction of weirs, the renovation and building of bridges and the reconnection of disconnected branches of Nidda. Besides the environmental aspects, another project goal was to make the riverside more accessible for local offering various ways for relaxation and recreation. (2,7)

Saltersgate Junior School has unveiled its new eco-friendly ‘living wall’ - believed to be the first of its type in a UK school. This was part of a larger refurbishment project. The 98-square metre architectural feature will help insulate the building and use surplus rainwater from the roof to water plants. The Scawsby school’s pupils have been involved in the creation. They will also be looking after it and use it as an educational area for studying different types of plants and insects (Ref 1 & 2)
