The FUTURE - a project of 100,000 trees in the Porto Metropolitan Area - is a planned and coordinated effort of various organizations and citizens to create and maintain native urban forests in this region, which needs to enrich its biodiversity, sequester carbon, improve quality of air, protect their soil and contribute to a better quality of life for regional people. The 100,000 Trees Project for the Porto Metropolitan Area” intends to restore 100 hectares of urban forest with native trees. (1, 2)

The "Ciobarciu wetland" project resulted in the creation of a wetland area of ​​about 224 hectares near the city of Iasi (30 Km distance). The area of ​​nature thus became in spring and autumn a significant resting place for migratory birds, and the specific types of natural vegetation are growing again, constituting a natural habitat for the locales specific to these places. The project was developed by the National Administration of the Romanian Waters alongside the Dutch Government in order to restore the area and to include it in the ecosystem of the place (1)

This NBS is a part of the "Horta à Porta" (allotments at the door) programme which enhances the economic, environmental and social dynamics of the Porto region through the creation of community organic gardens and the promotion of active involvement which empowers local people and institutions. The program is led by the Greater Porto Metropolitan Waste Management Service, LIPOR. Implementation of vegetable gardens began in 2003. In the Metropolitan Region of Porto, there are 23 of these community gardens totalling four hectares, and the forecast is for a large-scale increase in the near future(1)

Due to human interventions into the natural river flow with dykes, drainage of agricultural and grassland or cutting off its water bodies, the wetland Elster-Luppe had lost its groundwater base which decreased its biodiversity. With the support of the regional biodiversity fund and building on previous efforts, the city of Leipzig, together with partners such as the NABU Sachsen and research institutions, has revitalized, renaturalized and connected the water bodies of Leipzig's North-Western wetlands to one continuous watercourse since 2012. Its objective is restoring its ecosystem functions and increasing awareness for the importance of wetlands (4, 5).

In 2010, rehabilitation works on the Huveaune riverbanks, in the city of Marseille, were carried out by volunteers from three associations: Rives & Cultures, Planète Sciences Méditerranée, and Hunamar. Work included clearing, revegetation, and maintenance of riverbanks (Ref. 1). Since this initiative took place, the l'Huveaune Watershed Union has been formed and taken steps to formalize the rehabilitation of the Huveaune riverbanks (Ref. 2, 3, and 4).

The river Emscher is the symbol of one of the internationally most renowned industrial regions: the Ruhr area with its 5 million inhabitants and an important location of key industries such as steel, chemical, and materials industry. The revitalisation of the Emscher over the last 20 years marks a new phase in the region‘s history and is an impressive example of ecological and socio-economic transformation affecting all aspects of life along the river (Ref. 1).

Maritza Gardens is a residential complex with an abundant park environment along the north bank of the Maritza River. The inner part is a 5000 sq.m. park with luxuriant vegetation and facilities for recreation. The purpose of the complex is to allow residents to successfully combine city life with well-being. (Ref. 1; Ref. 2).

Citizen Farm was a start-up founded by Pierre Osswald (Ref. 3). The project began with an experimental urban farm in a vegetable garden of Raymond 6. The ozarium farm (a vegetable aquarium) uses a technique called aquaponia (Ref. 5). This technique grows all kinds of plants and vegetables indoors in an entirely natural way. Fertilizer or watering are not needed. Plants feed on the nutrients in the aquarium: water and fish discharges. In return, they purify and oxygenate fish water. It is an ecological and educational innovation which is surfacing as an "eco-responsible" trend. (Ref. 1, 2). The Citizen farm initative was ended in 2018 due to financial difficulties (Ref. 35).

This NBS refers to a curtain protection forest that was planted 6 km out of the city of Iasi in 2015 by the mayor of a commune next to the city. The benefits of this NBS embrace also the city of Iasi as a method to prevent flooding and to avoid strong winds in the area. Afforestation was seen also as a response to the existence of arid soil and abandoned crop fields in the area due to a large population movement of immigration towards Western countries (1)

The Werd Administration Centre contains a green park that provides a good variety of trees with an aesthetic view of the city. Ornamental cherry trees create a lively atmosphere, in the spring with their double-blossom flowers, and in the autumn as their canopy changes colour. This park has been renovated a few years back to increase habitat diversity. The building itself got another renovation in 2014. (Ref 1)
