The project was part of a series of development projects which addressed the water management issues of the city. (Reference 1) The rehabilitation of a lake in the Adyváros neighbourhood included the renewal of the water reservoir, surrounding green areas, footpaths, and vegetation, as well as the installation of a new street light system, benches, trash cans, and unique street installations such as an interactive message board. (Reference 2) The interventions transformed the lake and its surroundings into a popular recreational area, frequented by locals. Since the completion of the project in 2014, there have been minor developments to the lake and its area, such as the renovation of the playground. (Reference 4) Apart from Adyváros, several other lakes were rehabilitated in several neighbourhoods (Adyváros, Győr-Szabadhegy, Marcalváros). (Reference 6)

Győr and its surroundings boast many rivers, streams and lakes, and experiences intense flooding almost every year. The main goal of Nagy-Pándzsa project was to reduce the risk of flood and to regenerate the Nature 2000 area (Reference 7). Due to the reconstruction of the water transporting feature and the reconstruction of the flood-gate, the flood protection could improve and the pollution of waters could decrease. Therefore, the conditions of flora and fauna of waters improved and the size of the utilizable area increased (Reference 8).

In 2014, the municipality of Győr initiated a large-scale tree-planting programme which has planted approximately 1000 trees each year since it was started (Reference 6). As part of the programme, old trees that have become dangerous, withered or have outgrown their base are cut down, but much more are planted each year than the ones that are removed. (Reference 1). In the course of the program, mostly manna ash, European dwarf cherry, Norway maple, European hornbeam, large-leaved linden, London plane, and chestnut trees are planted, taking into account the local conditions. About 200 shrubs and thousands of flowers are planted each year. Flower seedlings have also been donated to citizens, with the goal of involving citizens in green space creation (Reference 6). An addition to the programme started on 1 July 2020 (Reference 6) and since then, after every child born in Győr, the parents can claim a tree that they can plant on their own or with the company Győr-Szol Zrt.

The Sowe Valley Project was a community-based project focusing on rivers restoration. It aimed to link the local community with the Sowe River Valley and to improve the valley’s biodiversity and habitats for the benefits of people and wildlife. (Ref. 2, 6, 11-13)

The renewal of the 220 sqm roof terrace of the Ministry of the Environment in 2010 focused on improving the thermal insulation of the building and the remaking of its green roof. The project was planned by the city council’s department for urban nature in collaboration with a landscape architect and implemented by a professional outdoor greening company (Ref. 2). The green roof won the award “green roof of the year 2013” and is also actively promoted as a model for green roofs, frequently shown to international guests of the Ministry. (Ref. 1).

The Bio Washing Machine is a combination of an Aquifer Thermal Heat Storage (ATES) system and biological natural attenuation of groundwater and is thereby mainly focused on groundwater decontamination and energy storage. The ATES system accelerates the biological degradation of groundwater contamination and provides sustainable energy because cold water is pumped through buildings during the summer to cool the buildings and hot water during winter for heating. The groundwater decontamination measurements are aimed at protecting water in order to provide safe drinking water (ref. 1, 2, 3)

“The Environment and Me project (TEaM) is operated by Warwickshire Wildlife Trust and CWMind (Coventry and Warwickshire Mind) and supported by Coventry City Council. (Ref. 1) It is an ecotherapy-based project which aims to enhance mental health and wellbeing. (Ref. 1, Ref. 2). It provides opportunities for outdoor activities at allotment sites, gardens, woodlands, parks and nature reserves – giving people some much-needed breathing space in the fresh air, whilst learning new skills, meeting new people and giving back to nature.” (Ref. 1)

The surface water system in the VINEX location Leidsche Rijn near Utrecht is a special water system. Nowhere in the Netherlands is the surface water of such a large urban area treated in such a sustainable and climate-proof manner (ref. 2). In Leidsche Rijn, a relatively new city district of Utrecht, a sustainable closed circuit water system was introduced including natural wetlands, bioswales, pumping stations and permeable paving which filters stormwater organically. It is viewed as a more sustainable solution compared to traditional stormwater infrastructure because it benefits biodiversity (e.g. by means of fish passages) and prevents the need for storm water facilities and the influx of unfiltered surface water from elsewhere (ref. 1-3).

Persistently low water levels on the Moson-Danube since 2002, caused by the sinking of and loss of supportive effect from the Danube, caused severe ecological, agricultural and water flow problems (Reference 12). The project, funded by the EU through the Széchenyi Development Plan, was aimed at improving water management and rehabilitating the degraded ecosystem of the area (Reference 1).
The project consists of two phases: the reconstruction and regeneration of the river in the entire Moson-Danube area, and the creation flood gate at the delta. The first phase was completed in 2015, the second phase started in 2017 and is planned to finish in 2021 (Reference 12 and 13).

A project of 200 plots for an urban orchard on-site at Parque de las Aguas was created, where individual citizens, social groups, and companies can rent the lots to cultivate their own produce. The orchards hold educational programming for patrons and visitors as well. (Ref. 1,2,4)
