The project focused on the creation of a rooftop community garden located near a metro station in Bilbao that aims at educating the residents of the neighborhood on how to grow vegetables, how to eat healthily but also offers free practice hours for every person that wants to have their own plot. The project was initiated by the Bilbao's Center of Innovation, a center that aims to contribute to the economic, strategic and solidarity development of the Municipality of Bilbao (Ref 1).

As part of World Tree day celebrated on March 21, 2017 the Sintra Service for Protection of the Nature and the Environment (SEPNA) as well as the Sintra Branch Segura School carried out several education workshops for school children to inform about the importance of tress for our natural environment and carried out afforestation and reforestation actions inside the green spaces of Sintra.

The lake, which is fed by brook Rio Archetti, is located in the highest section of the park, immediately down from the Villa Doria camping ground, in an area of the public park that is not very frequented. It used to be in great decline, because of many maintenance and environmental factors. This intervention brought it back to its original estate, recreating the original historical and natural value the area had, highly popular among local residents as a green place where to enjoy calm and silence in the center of the city.

The environmental NGO Dodo started their Guerilla Gardening projects in 2009 with a garden on the wasteland by the main railroad tracks in Helsinki, Pasila. The key idea was to make use of temporary derelict spaces. Raised beds were constructed from old pallets and filled with donated soil. Crops were grown by local citizens and provided both food and aesthetic beauty on the otherwise unused area.
In 2012 the project developed into "Turn Table - The Urban Garden", as the garden was supplemented by a small pop-up restaurant and café in a movable greenhouse (Ref 1, 2, 7). The Turn Table garden space was organized to promote awareness and discussion on the ecological and social aspects of food. The urban garden project included not just the greenhouse, but also an apiary, cultivation beds, a summer café with a terrace, and a market (ref. 4).

There is a quickly growing number of residents, who want to grow their own food within a short distance of their locality, but new areas for allotments are not sufficient. The environmental NGO Dodo started a "guerilla gardening" movement, part of which is the temporary use of otherwise abandoned spaces. Specifically, at Kalastama area, an empty space waiting to be built upon, 36 farmers created an urban farm with recycled industrial bags to grow crops that can be removed afterwards (ref. 1). The garden in Kalasatama is a collaboration with the city of Helsinki, part of the temporary uses of the area, which in the next 20 years will be built into a new urban district of Helsinki (ref. 4)

The Zabalburu square is a square located in the city of Bilbao at the confluence between the streets Autonomía and Hurtado de Amézaga . In 2008, the creation of the square, situated on one of the main roads leading into the city, enabled the recovery of almost 3,000 m2 for leisure and recreation space. It was designed as a forest that protects citizens from road traffic, and has 77 different sized trees that act as a plant barrier. This NBS was necessary since it is located in a quite crowded area (Ref 1)

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.

An enterprise called Alicante Forestal constructed a vertical garden in Mallorca, in an office in Santa Ponca (Ref 1). The garden was installed indoors, making a green wall in the headquarters of the local business (Ref 1). There is in 2020 not only this garden, but a service given by Alicante Forestal in Mallorca to design and install these in other parts of Spain, as well as courses for building these gardens in different countries in the world including Spain, Colombia, Ecuador, Argentina and Mexico (Ref 3).

This project deals with the creation of a green roof and a green area around the new headquarters of the IDOM Group (an independent multinational company that offers professional integrated services in Consulting, Engineering and Architecture around the world), located in an old French warehouse (a customs warehouse) on the Deusto canal in the port of Bilbao. It has an area of ​​14,400 m2 dedicated to offices, research and development spaces such as white room and workshop prototypes, and social spaces. (Ref 1)

As part of the EU Life+ CITYWATER project (of 3 cities), a sustainable stormwater management solution based on biofiltration was implemented in Maunulanpuisto Park in Helsinki, in order to purify rainwater and meltwater and improve water quality in the Haaganpuro Brook.
As the drainage area is heavily trafficked and paved with asphalt, high solid, nutrient and oil levels have occasionally been measured in the rainwater and meltwater entering the Haaganpuro brook. Such contamination is harmful to the fish stocks (e.g. trout) and other organisms in the brook. The biofiltration solution was the first of its kind in Helsinki. The solution also supported the City of Helsinki stormwater strategy, which aims at changing management towards sustainable solutions and states that stormwater should in first hand be infiltrated on spot, where it is created (ref. 1).
