Green Infrastructure (GI) is a network of natural and engineered ecological systems, localized at landscape scale and fully integrated with the built environment. GI provides a wide and diversified range of Urban Ecosystem Services and is able to increase the resilience of the urban systems toward several risk categories (i.e. hydrological and Climate Change risk). Particularly, two main components of the GI are here presented and discussed: Non-Urbanized Areas (NUAs) and Best Management Practices (BMPs). NUAs include cultivated land, abandoned farmlands, grassland, woods and shrubs, often located at the peri-urban cities’ fringes and provide all the major categories of Ecosystem Services. BMPs are technics developed to control pollution, runoff and, in general, to ensure a sustainable urban water management, such as: green roofs, pervious surfaces, constructed wetlands, detention basins, infiltration basins, filter drains. BMPs aim to mimic the natural and semi-natural structures present in the environment furnishing similar provisioning, regulating, supporting and cultural functions and services. An Ecosystem Services conscious planning and design of GI that is based on these components might be able to integrate human activities and environment looking both at ecological and cultural/social issues. We first present a methodology for characterizing NUAs as a planning support tool for enhancing the current land-use assets aimed at the enhancement of the overall provision of ecosystem services in an high sprawled urban context. The UGI’s capacity to control the urban storm water is then discussed by presenting a modelling approach applied in a compact district of Bari city.

Abstract
Green Infrastructure (GI) is a network of natural and engineered ecological systems, localized at landscape scale and fully integrated with the built environment. GI provides a wide and diversified range of Urban Ecosystem Services and is able to increase the resilience of the urban systems toward several risk categories (i.e. hydrological and Climate Change risk). Particularly, two main components of the GI are here presented and discussed: Non-Urbanized Areas (NUAs) and Best Management Practices (BMPs). NUAs include cultivated land, abandoned farmlands, grassland, woods and shrubs, often located at the peri-urban cities’ fringes and provide all the major categories of Ecosystem Services. BMPs are technics developed to control pollution, runoff and, in general, to ensure a sustainable urban water management, such as: green roofs, pervious surfaces, constructed wetlands, detention basins, infiltration basins, filter drains. BMPs aim to mimic the natural and semi-natural structures present in the environment furnishing similar provisioning, regulating, supporting and cultural functions and services. An Ecosystem Services conscious planning and design of GI that is based on these components might be able to integrate human activities and environment looking both at ecological and cultural/social issues. We first present a methodology for characterizing NUAs as a planning support tool for enhancing the current land-use assets aimed at the enhancement of the overall provision of ecosystem services in an high sprawled urban context. The UGI’s capacity to control the urban storm water is then discussed by presenting a modelling approach applied in a compact district of Bari city.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
