Green densification model

The program aims to change gray urban courtyards into friendly places - the green oasis for neighborhood meetings and resting areas. Small project proposals developed by the housing associations for the revitalization/transformation of courtyards from all over the city compete for co-funding (up to 75%) from the city council. Many projects (over 86 by the year 2015) have been funded and implemented since the beginning of the initiative in 2008.(1)(2)

The Anfield Regeneration project was founded in 2013 with the aim to improve the area and its neglected housing stocks. It was set up by the Liverpool council and the Liverpool Foot Club, along with developers Your Housing Group and Keepmoat. The activities include the development of new and refurbished housing, the development of a new public square including commercial and retail premises, a revitalised high street and the expansion of Anfield Stadium (Reference 6) . It also includes the creation of public spaces and selective garden extensions in the area following the demolition of a number of derelict homes (Reference 1).
The partnership has stated that more than 600 new homes have been built, with 600 existing properties refurbished. The project aims to create 1000 new homes and is scheduled to be completed in 2020 (Reference 6, 8).

The present intervention is about the rehabilitation of the freedom square (Námestie hraničiarov) (formerly Gottwald square) in the city district of Petržalka of the city of Bratislava (9, 11). The area of the intervention is about 1 ha. The pavement was replaced by grass areas, trees, and flower beds in the square’s alleys. A water capturing and irrigation system was also installed to ensure resilience to drought. The project was implemented by the city district of Petržalka, which is - with 100,000 inhabitants - one of the larger and most densely populated districts of Bratislava. (1)

The intervention was planned to revitalize and clean a derelict area close to the university hospital in Blato. Before the project was implemented, the area was an informal waste disposal site for the locals. The area was neglected for more than 30 years. Initially, Mayor Milan Bandić planned a large urban park with a thermal spa in the spot. The area was cleaned and some of the constructions had begun, but later it stopped due to some political hurdles (Ref 1, 2).
The first phase, cleaning the shrubs and waste from the area has been completed in 2015, but the use of the area has not been determined yet, therefore the project has not been completed (Ref 1).

The curtain forest at the end of the city is a project that was initiated by the Timisoara's Municipality in 2001 by planting different tree species and creating a barrier for high-temperature summers. It's 60 m high and it was designed to stand in front of very strong winds especially since Timisoara is a city located in a very plain area. Now, it comprises 23 hectares and the municipality aims at 50. (2)

Sofielund invests in a sustainable area. Carpool/joint recycling centre were some of the proposals discussed when property owners, Malmö city and some experts discussed how Sofielund could become more sustainable in the future. The idea is that the environmental days in Malmö (e.g. a workshop) will lead to an action plan to make Sofielund greener. Property owners Sofielund has been at the forefront of a local sustainability work that can be a model for the rest of the country. In February 2017, a memorandum of understanding was signed about concrete efforts to strengthen the Sofielund area (Ref. 1, 2). There is a strong political support for the work that is being done in Sofielund and the BID concept is now upscaled to a sixth project area called Case Sofielund. (Ref. 6).

With its parking areas, ponds, the Lutter stream, playground facilities, walking and jogging paths, the green corridor of Bielefeld, called Luttergrünzug offers recreation opportunity to around 36, 000 people, living in the surrounding areas. As a link between the eastern city center and the district of Heepen, it also enables walking and cycling routes for commuting and shopping away from the busy streets of the city (7). However, the green corridor has been showing some structural and functional defects such as the silting up of the ponds, conflicts between pedestrians and cyclists and the increasing overgrowth of the green belt (8). In order to solve these problems, the renovation and redesign of the Green Corridor was proposed. The regeneration project addresses different needs and requirements of the municipality, namely providing the comfortable infrastructure for pedestrians and cyclists, and the increase of attractiveness of the neighbouring residential areas. In the planning process, special attention was paid to the improvement of the draining system and the reservoirs of the area that will protect the Belt from flooding. (8)

Two regeneration plans were developed with citizens' involvement and presented to the political committee. In 2017, the implementation of the "smaller" variant was voted for, which was already presented in the first citizens' workshop (1, 4).

The Svoradova small park is an NBS site of the Bratislava zelenaj project. The newly renovated park (once part of the historical Pálffy Garden) on Svoradova Street in Old Town was previously abandoned and neglected. (14) It is part of the citywide Bratislava zelenaj project aimed at protecting and promoting the welfare of the city’s vulnerable citizens from the effects of climate change, (1) providing a safe recreational space for children (with a small playground for playing and swings). The park also has new lighting, and the whole space is home to new flowers, bridges and trees. (10, 12, 18)

The BiodiverCity-project aimed to develop products, services and processes which support and enhance the city’s biodiversity and thus contribute to a vision of a green, attractive and healthy city (ref. 1). The project had been divided in three steps, step 1 involving preliminary studies and step 2 was practical work for two years. During step 2 different cases were identified to test new ways to e.g. increase the city's biodiversity. Step 3 included spreading to other sectors through seminars, education and exhibition activities. It also included the commercialization of green solutions (ref. 2).

Agora Budapest is a large scale urban redevelopment project initiated by private investors. Besides implementing five high-quality office buildings, the investors aim at creating green public spaces the size of 7000 square metres in order to provide a healthy and vivid working environment. The green surface involves green roofs, parks and tree lines, all which will be irrigated using collected rainwater. The solar panels on the roofs of the buildings are also part of the sustainability plans of the investors. (Ref 1. and Ref 4.)
