Effective management

"The Urban forest strategy (UFS) is a central part of an innovative overarching policy framework of the City of Melbourne underpinning the city's aim to create healthy ecosystems for people and nature" in the period between 2012-2040 (1 p9). The UFS outlines a scientifically-vetted long-term process to re-nature the city with a diverse selection of urban trees and open space for and with the citizens, combining elements of an eco-managerial governance arrangement with an open and reflexive co-governance approach. (1 p11). The Strategy concentrates on 6 areas to achieve its goals: canopy cover, forest diversity, vegetation health, water quality and soil moisture, urban ecology and environmental stewardship among citizens.

Henteleff Park is a 'passive park' located along the banks of the Red River and Normand Creek in Winnipeg where the rural character of a landscape that nurtured early Métis culture, Winnipeg’s budding market garden industry and the Henteleff family has been reserved (2). In the 1980s and '90s after being the city's tree nursery it was up for real estate development when "a group of volunteers from the nearby residential area, led by the Henteleff family, presented a convincing plan that showed the value and potential of the site as a public park. As a result of successful lobby efforts, the land was rezoned as a park in 2002 and named Henteleff Park after the original owners of the farm" (1 p21).
With its grasslands, riparian forests, Red River banks and the Normand Creek, the Park is home to a diverse plant and wildlife, providing refuge for songbirds, a spawning area for fishes and a serene sanctuary for community residents to enjoy a quiet respite from the bustle of the city life all around (2).

Parc Marianne is an ecodistrict that aims to address multiple challenges such as climate action for adaptation, environmental quality, flooding, and in response to the high population growth in Montpellier. Parc Marianne is connected to public transportation, has bicycle lanes and car parks, and the sidewalk is shared between pedestrians and bicyclists and structured with trees and other greenery. The park was certified with the ecodistrict label in 2015 following requirements like environmental sustainability, thermal performance, quality of life, nature and biodiversity, and mobility (Ref. 1). Parc Marianne is a mixed neighbourhood with an ability to combine city and nature, quality of life and centrality (Ref. 2).

The Tree Strategy is a municipal action plan in progress, aiming to address some of the main sustainability challenges described in the Environmental Program of Malmö City. Its main relations to sustainability challenges include improved health and well-being, decrease differences in those among different social groups and increase biodiversity. The Strategy includes a range of possibilities for evaluating its ecological and social success (ref. 1).

Initiated by the City Administration, NGOs and citizen groups, public funds have in recent years been used alongside partnerships with local businesses, landowners and citizen initiatives to invigorate the East Quarter. This initiative was proposed through the redesign, extension and new development of parks, greening and communal use of vacant plots, the establishment of new urban forests, the setting up of new communal gardens, and the planning and partial implementation of a green corridor for cyclists and pedestrians.
Within this large project, three NBS areas actively contributed to the improvement of the Quarter: Querbeet, Bunte Gärten and Parkbogen Ost (1).
Querbeet is a community garden in the Eastern district of Leipzig, formed in 2012. The garden is lead by democratic self-governance principles where the focus is on shared space, with a focus on enhancing cultural interactions and encouraging active citizenship (1). Since 2017, the plot of the garden has reduced, however, the non-profit organisation formed two new gardens: a community garden and a school garden where environmental education the main activity (2)
Bunten Garten (Colorful Garden) is a community garden and registered refugee aid association that aims to bring residents and refugees together (3) The garden was revived in 2015, and since offers opportunities for recreation, wellbeing and informal support to refugee families (1).
Parkbogen Ost is a scheme focusing on developing unused railway tracks as an arch-shaped, green mobility corridor running along the perimeters of much of Leipzig’s East Quarter and connecting the quarter’s green spaces and providing easier access, by foot or bike, to the city centre as well as to surrounding areas.

With the progressive monopolization of the seed trade and the industrial cultivation of hybrid varieties as well as the restrictive seed legislation, the cultivation of old crops has steadily declined and about 90 per cent of the old crops have been lost. This initiative aimed to reverse the trend by the cultivation of old crops, dissemination of their seeds among farmers and educational workshops to protect and increase their biodiversity.

The project involved the building of the propagation garden on an approximately 4500 square meter area in Ricklingen. This project started in 2013 and it involves interested residents, cooperating with Transition Town Hannover (TTH). The city of Hanover supported the initiative by providing the property and financial aid for the construction of the garden. The project has been provided with professional network from BUND (Kreisgruppe Region Han­nover), the School Biology Center, the VEN (Association for the Conservation of Crop Diversity eV) and Leibniz University, Institute of Horticultural Production Systems and the Chamber of Agriculture In 2014, the basic restoration work on the property was completed. (Reference 1, 5).
Frame beds were installed in 2016 while a garden house was built in 2017. The project was funded by the City of Hannover until 2017 but it continues until the present with the help of volunteers (Reference 9).

The project "Sustainable Support Program for Greening Buildings and Minimizing the use of space using the example of Hanover" was established jointly by BUND (Bund für Umwelt und Naturschutz Deutschland) and the state capital of Hanover. The goal of the project is to transform as many barren house walls and dull grey roofs and asphalted areas into green oases throughout the city. Since May 2013, all house and landowners, housing associations and building communities have been able to apply to the BUND for a subsidy for green roofs and facades. On 2017, the project was expanded to include unsealing of areas like inner courtyards, driveways, etc, thus creating new green areas. Advice on the correct greening measures and on professional unsealing have been also offered by BUND.
The project is funded by the state capital of Hanover, the German Federal Environmental Foundation (DBU), the Sparkasse Hannover and by proKlima. The "Green Hanover" funding program will end on December 31, 2020. (Reference 1)

The project is a close-to-nature maintenance concept that combines the diverse usage requirements in public green spaces and the promotion of biological diversity through near-natural care. (Reference 1) It aims to promote biodiversity in the area through the plantings of local trees, installation of deadwood stacks, dry stone walls and boulders, which will help in the increased interconnectedness of the green areas and provide for structured habitat for the local species. The initiative also involves development of ecological standards for the handling of green spaces in the country, such as natural care practices that will protect local biodiversity (e.g. adapted mowing regime for lawns, flower meadows). (Reference 1, 2)
The "Urban green - species-rich and diverse" project is a cooperation project of the alliance "Municipalities for Biological Diversity eV" (Alliance) and the German Environmental Aid eV and with the participation of the five partner municipalities Frankfurt am Main, Hanover, Wernigerode, Kirchhain and Neu- Response. The project is funded in the Federal Biodiversity Program by the Federal Agency for Nature Conservation with funds from the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety. The experiences and results of the pilot project are further incorporated into the maintenance requirements for public green spaces in the urban area in other municipalities (Reference 1, 7).

The civil society association "Permaculture vorm Eichholz" has made it their agenda to turn a since 2016 abandoned farmhouse into an experience-based, educational, co-design space around the concept of permaculture which is an ecologically inspired design concept for creating resilient and durable agricultural areas while maintaining the diversity of cultural and natural habitats. The farm, which was established in 2017, promotes alternative cultivation methods and energy concepts via seminars and workshops and constitutes an experimental lab for interested citizens who can implement their own ideas or even take over responsibility for parts of the farm they develop and cultivate themselves (Ref. 1, 2, 3). The leaders of the project also plan to implement a sustainable energy concept, with the goal of making the farm self-sufficient in it’s energy consumption by producing renewable energies in a variety of ways.

After relevant local regulations had been adapted and allowed for keeping apiaries in the city of Białystok, in 2016, the Institute of Biology at the University of Bialystok put six beehives on its rooftop. The initiative aims at increasing biodiversity and pollination in the city. It promotes beekeeping and sustainable production and consumption patterns, and the honey is a brand product of the University [1,3,4].
