cultural landscape. Overturning the traditional approach, which starts from
open spaces, in particular from what remains of the peri-urban countryside, it
proposes new urban planning and infrastructure directions and new strategies
for sustainable development.
The Marche REM also confronts these themes of contacts between the eco-
logical network and the city . It concretizes the idea of a city penetrated by
environmental networks that communicate with the other networks and con-
nect green areas and white areas, contaminating consolidated fabrics and
undefined city fragments, contributing, together with other infrastructure net-
works, to the definition of the city structure . Projecting environmental net-
works for urban areas can produce important strategies for “ green networks
intended as “large parks” [22], within which welfare strategies unfold (Figs.

Cities and Territories
The city is a fertile element with a vital relationship to the territory. The design
