In the monographic issue, there is an interview with Carme Rosell, Director of MINUARTIA, on ecoducts, which are large infrastructures above roads and railroads with complete habitat restoration to favour the continuity of habitats on both sides of the infrastructure. Rosell points out that drafting a good project requires deep knowledge of ecosystems to establish where the infrastructure should be established, and attention should be paid to three key factors that determine its effectiveness: 1) location of the infrastructure, 2) restoration of its surface and 3) fitting-out of the entrances. Often attention is paid only to the building type, but focusing on the restoration and integration of the infrastructure into the environment ensures its effectiveness. Finally, she underlines the need for cooperation among engineers, fauna experts and landscape experts to obtain functional and effective structures.
The leading article in this landscape issue defines a ‘green corridor’ as an element that can play diverse roles, ranging from ecological connectivity and territorial permeability, to the creation of the urban fabric or spaces for social and cultural exchange. An article by Richard T.T. Forman opens the issue, in which he explains general and theoretical concepts of green corridors. The issue also includes several articles on case studies from around the world, projects that arose from tenders in Barcelona and a scholar’s work. It focuses in particular on the role of green corridors in metropolitan areas.
