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
Full text linkThis 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
Riconoscere la sostenibilità. La manutenzione dei caratteri della città storica
No full textIl contributo da conto dei risultati della ricerca sviluppata in seno al DICATA avente ad oggetto la messa a punto di criteri per la valutazione della compatibilità ambientale dell'intervento di manutenzione negli spazi urbani. In particolare, si sviluppa la tesi della manutenzione urbana come occasione per meglio integrare il paesaggio urbano con il contesto naturale nel rispetto dell'identità dei luoghi e delle valenze ambientali storicamente espresse. L'analisi del ciclo di vita degli elementi tecnici costitutivi dello spazio urbano aggiunge un ulteriore elemento di riflessione sulla sostenibilità intrinseca della città storica e definisce alcuni possibili scenari per gli interventi a farsi
Identification and Assessment of Urban Coastal Areas Problems and Issues
No full textSite features could have a great importance in EMAS application. The assumption concerns the adoption of an holistic approach to site description, including social issues and the existent policies and measures for the urban development. The Italian proposal takes references from ICZM programme and from ICAM research on coastal environment so the site description methodology is based on indicators coming from the studies of ICZM programme. By the site analysis, methodology tries to carry out an easy approach to EMAS finalized to point out the focal issues (and, of course, the most severe impacts) for deeming the site vulnerability

La gestione sostenibile delle aree urbane costiere Limiti ed opportunità della certificazione EMAS nell'esperienza comunitaria MedCOAST.Net (Mediterranean Cooperation for On-Shore Accessibility and Sustainability Themes. Network for managing urban coastal areas)
No full textIl libro si propone di definire un quadro di riferimento scientifico entro cui ricondurre le procedure per la registrazione EMAS da parte di enti pubblici di piccole dimensioni che vogliono qulificare la gestione di parti del territorio caratterizzate da specificità ambientali. Se infatti nell’ambito industriale la corrispondenza tra processo produttivo, impatti e ambiente risponde ad una logica causale molto precisa, di cui l’impresa governa tutti i passaggi, lo stesso non vale per le amministrazioni comunali le cui attività (sia dirette che indirette) possono determinare impatti su un maggiore numero di siti caratterizzati da performance ambientali molto diverse e che – in aggiunta – ricadono sotto la responsabilità di più enti. In particolare la ricerca condotta dal DICATA in qualità di partner scientifico del progetto ARCHIMED (anche supportata dall’interazione con l’Università della Tessaglia) ha cercato di verificare le possibilità di utilizzare EMAS come strumento di governance integrata in ambiti caratterizzati da condizioni di pregio e/ o vulnerabilità ambientale. I risultati della ricerca sono la definizione di una Best Practice che ha nel caso studio del promontorio di Punta del Capo, nel Comune di Sorrento, il suo riscontro applicativo
Environmental performance of the urban form
No full textThe paper deals with the experience of a four-year research at the University of Naples “Federico II” focused on environmental performances of urban space in small towns and villages of Southern Italy. The study proposes a knowledge-oriented methodology aimed at enhancing the value of the urban form in terms of relationships between natural and built environment, empirically demonstrating the existence of a (somehow implicit) ecological design approach of the primary urban patterns that characterizes “urban signatures” in terms of pattern itself, building shape, use of materials, construction technologies.
The research wants to point out the value of the original construction process and it aims at highlighting the coherence between city form and the natural environment notably focused on the sustainable use of local resources (vegetation, soil and water) corresponding to ecological cycles and fit on human activities.
Ancient towns and villages in Southern Italy are a meaningful example of ecological design in which built technologies were strongly oriented by the site and by the availability of natural resources. They intermediate the relationship between natural and built environment and supply dwelling performances coherently with local context. Harmonization of nature and architecture in many historic towns shows this positive integration and represents an important topic in terms of urban management and urban planning.
Ancient villages, especially, present urban patters deeply linked to topography and to the natural environment thus also urban signatures are designed in such a way to give environmental benefits to the whole built-up area in terms of improving microclimate, managing rain fall water and controlling environmental risk. Moreover urban signatures are featured by a common constructive approach aimed at a sustainable use of local resources, as some sort of “instinctive care” to Life Cycle of building materials.
This kind of implicit sustainability of urban space is now treated by the impact of modern transformation of historic assets - even by the aim of rehabilitation or maintenance - in which the misunderstanding of primary, sustainable building processes could upset local ecological balance and site identity. The common and acceptable instance of updating services and performances of historic urban space by modern dwelling functions – such as accessibility by car, improving infrastructure and nets, developing commerce, etc. - ought to be compared to the original state of the site and ought be adequate to local, specific carrying capacity.
According to these remarks, the purpose of the study is to propose a methodology for “scanning” city space in a way of emphasizing the coherence between the urban pattern, urban signatures and some key constructive elements.
Three key assumptions drive the study. First assumption is the ante litteram sustainability of ancient town, tangible evidence of building tradition devised by economic opportunity and by environment understanding, a special condition that drove constructive solutions towards forms and functions adequate to local carrying capacity According to this, the second assumption regards the application of LCA to the urban signatures. The study aims at recognizing the original life cycle design approach aimed at preserving natural resources, reducing transport costs and optimizing the life service of each element. Third and last assumption concerns the qualitative approach to LCA. It is targeted on a sort of eco-balance more than an inventory itself, focusing on pre-industrial constructive process and local design strategy. From this side, attention will be given at some environmental parameters such as the use of natural resources (local and global), the life cycle management (urban and natural), the re-use and re-cycling of materials that could act as constrains in rehabilitation or management projects
Environmental Management of Urban Coastal Areas. Results of EMAS Application and Evaluation of the Pilot Actions
No full textThe Italian contribute concerns the opportunity of registering the site of Punta del Capo in Sorrento Municipality through the EMAS process. The approach works on a key site based methodology, by means of representing site environmental specificity and the territorial dynamics. Such approach integrates the wider MedCoast.Net Project in terms of :
- methodology, giving priority to first step of Registration in order to highlight precise issues of urban coastal area;-
- opportuntity, working under the umbrella of Regional Urban Park destination;
- consistency, providing technical and operative solution for promoting sustainable tourism at local level.
Further, the key site approach looks a good opportunity for extending EMAS registration to other homogeneous area of the Sorrento Municipality and to the traditional landscape of Sorrento Peninsula. The approach is consistent with some recent EU project experience based on simultaneous registration of a number of firms and Authorities operating in the same geographic territory (Cluster Approach) providing a kind of Territorial EMAS that could improve both competitiveness and environmental quality in the territory
