Infrastrutture verdi e servizi eco-sistemici in area urbana: prospettive di ricerca per la progettazione ambientale / Green Infrastructure and Ecosystem Services in Urban Areas: research Perspectives in Environmental Design

This article is a critical essay about the relevance of green infrastructures in reducing urban vulnerability with respect to the climate change impacts. The Author aims at demonstrating the relations between the presence of urban green infrastructures and the amount of the eco-systemic services provided by. The study takes as a key reference the naturalness gradient expressed by the different typologies of urban green areas, including artificial surfaces (roofs and green facades ), bare soils, brownfield areas. The study outlines a research perspective for the urban green infrastructures according to the technological and environmental requirements of the intervention, resulting from listing, cataloging and hierarchization of the ecosystem services provided by both the different components of a green infrastructure, as well as the specificity of techniques and plant materials used in the project. This article is part of a wider research on human-made soils in urban areas, and it summarized some of the main advances that the Author has produced since the 2012.
