Collection of monitoring data at specific time intervals during the project to aid evaluation

Neptune Grass or Mediterranean tapeweed (Posidonia oceanica) is endemic to the Mediterranean Sea. This priority seagrass species forms large underwater meadows that are an important part of the marine ecosystem. However, there have been declines in its population due to mechanical damage, coastal development and eutrophication.
The main objective of the intervention was to safeguard and to restore 2 Natura 2000 network sites for the conservation of P.oceanica habitat in the Lazio region(1), being the NBS intervention the restoration/protection of the underwater meadows and the improvement of the awareness/importance of this marine habitat type, a priority for conservation(EU Habitats Directive).

The redevelopment of the Alcantara square is part of the program A SQUARE IN EACH NEIGHBOURHOOD, implemented by the Municipality of Lisbon in 2017 onward. Besides the road re-organization, the project includes specific elements. The NBS includes the creation of a public garden, cycling path, playground facilities and introduction of new trees (Ref.1). The residents of the neighbourhood were asked to participate. The participation process aimed at obtaining from the citizens an evaluation on different pertinent questions in the experience of the public space, results showed: space for pedestrians, improve green spaces and urban living (Ref.1).

The Water of Leith is home to a wide diversity of plants and animals. The river performs an important flood control function in the city. A management plan envisions to create a healthy river that flows through a green corridor from the hills to the sea and is a haven for wildlife, is enjoyed and managed by the public, and is valued for its built and cultural heritage. The current intervention is about an extensive Flood Prevention Scheme. Walls and other flood defence measures have been constructed from Murrayfield downstream to Bonnington. A re-modelling exercise is being carried out to include the impact of climate change on the river system and the efficacy of the flood prevention scheme. The Water of Leith Conservation Trust works to conserve and enhance the river, its heritage and wildlife. It also promotes education and recreation and works with volunteers and community groups (ref 1, 2, 3).

"The desire to integrate trees in the heart of Nancy constitutes a long-standing commitment. The first Charter for Trees of Nancy was signed in 1996. Plant diversity was strengthened and the protection of trees accentuated, in particular thanks to the requirements of the Local Urban Planning. In 2013, the new version of the Charter will make it possible to engage all the actors of urban policy to increase protection of the tree, to be vital to biodiversity and to the quality of the living environment" (Ref. 1). "New legal, urban, ecological and social issues have emerged. The old charter now requires improvements in the face of certain evolutions. It was decided to renew it. This new document is in line with the previous one and faces the new issues of the trees in the city" (Ref. 1, p 9).

The £1 million project aimed to transform the area from arable land to a high-quality wetland by creating a number of interconnected reed beds and water bodies. The project recreates part of the old wetland landscape that used to exist on the edge of Doncaster 200 years ago before it was drained for other uses. A major benefit of expanding the wetland will be to provide better quality water for local communities and reduce the impact of flooding in the area. The project is a collaboration among WWF, HSBC, Yorkshire Wildlife Trust and the European Union. (Ref 1)

In 2017 the municipality of Lisbon approved the program called "A Square in each neighbourhood". The municipality was seeking to revamp different neighbourhoods' green areas with the help of the citizens and collect contributions from the population most directly linked to the intervention sites. In this context the redevelopment of Campolide Street was based on the need to create better pedestrian accessibility in the detriment of traffic, improving the circulation of elderly in wheelchairs and children, the creation of a playground and the increase of green areas by planting more trees and create an element of water (Ref. 1).

The project area comprises the morphological floodplain of the Rhine to the north and south of the city of Karlsruhe and sections of the river Alb, covering an area of about 7.665 hectares in total. Alongside Karlsruhe, five smaller communities in the neighbourhood contribute to the project as partners. Due to the channelling of the Rhine, the construction of dykes and the isolation of river channels, the area has lost its natural floodplains and precious habitats and became more vulnerable to flooding. Major objectives of the project are the re-introduction of natural floodplains and the enhancement of natural habitats for local flora and fauna. (Ref. 7). The project included an exceptionally wide range of measures including species protection measures, the complete desludging of parts of the Rhine, the re-establishment of softwood and hardwood forests typical of the floodplain, the construction of bridges, the natural remodelling of the entire river Trench systems and the creation of new bodies of water. (Ref. 9) The project also provides environmental education, informing the public about activities and encouraging their participation (Ref. 7)

The Mab Lane Community Woodland was planted on a former playing field at Mab lane and Croxdale Road West in Liverpool. It is a part of the larger Mersey Forest initiative which has been increasing the amount of woodland and green spaces across Cheshire and Merseyside since 1991.
The new woodland which has a network of native trees, wildflower meadows a community orchard as well as seasonal wetland areas and footpaths, was officially opened by the local community in 2010. It also includes new pathways for walkers and cyclists and areas for family picnics (Ref. 2, 10). Mab Lane Community Woodland is a partnership project involving the Forestry Commission, Northwest Development Agency, Mersey Forest, Big Lottery, Riverside Group, Liverpool City Council and the Local Community (Ref. 10).

Nancy has the most community gardens in France. While these gardens are generally designed at the initiative of associations or collectives of inhabitants, in Nancy, they are part of the urban development plans.
This demonstrates a real desire from the city to bring the inhabitants closer to sustainable development while providing them with the means to create greenery in the heart of the city (Ref. 1). The Plateau-de-Haye district, where green space was recently created, allowed the emergence of many plots (Ref. 2).

In 2007 the Lisboa City Hall began the development of a strategy for urban agriculture, having created in 2011 several allotment parks. Beyond the provision of plots, the Council also provided the fences, shelters for storage, water irrigation, training and technical support. In 2011 there were already 56 plots of 150 m2 at a location named Granja Farm (2)
