Accessibilità post-pandemia: riflessioni sullo spazio pubblico
2021
The correlation between the psycho-physical well-being of citizens and the provision of green areas has been one of the cornerstones of urban planning since its inception, as its constant commitment to adapt cities and territories to emerging challenges. The spread of SARS-Cov-2 has changed the relationship between citizens and urban space. The public space, has been limited and banned, confining citizens within their private space and the psycho-physical well-being of citizens depended only on the quality of the domestic space.The pandemic represents a moment of reflection and research for the disciplines that deal with the quality of life of citizens. The pandemic crisis may be an opportu…
Urban green spaces and urban planning instruments for the protection of ecosystem services: proposals for re - thinking urban legislation in Sicily
2016
According to the Ecological Society of America (2014), more than half of the world population (3.9 billion inhabitants on a total of 7.2 billion) resides in urban areas where 75% of energy consumption and 80% of the greenhouse gases emissions are concentrated (UN-HABITAT, 2012). This data, inevitably, show cities as a patchwork of environmental issues (as well as social and economic issues) and of threats to the integrity of the ecosystem services. The damages suffered by these services, due to transformations of basic territorial resources in the name of an illusory global prosperity, continue to have negative consequences not only in environmental terms, but also in economic terms, as hig…
More nature in the city
2020
According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
Valorisation of urban green areas for producing renewable energy and biochar as growing substrate of Sicilian aromatic and nutraceutical species in a…
2020
This work is aimed at evaluating the possible building up of a gasifier for the energy valorisation of residual biomass deriving from urban areas and their surroundings. The area and the volumes of supply and economic convenience have been determined by implementing a GIS-based geographic method to the localisation and quantification of non-uniform elements of plant biomass. The pyrolysis and gasification processes of the lignocellulosic biomass obtained from pruning and maintenance operations of the urban and ornamental green include the production of a residual amount of biochar. The biochar can be used in agriculture as a soil improver and a substrate alternative to peat in the sustainab…
Public and Private Economic Feasibility of Green Areas as a Passive Energy Measure: A Case Study in the Mediterranean City of Trapani in Southern Ita…
2022
Green infrastructure in urban environments provides a wide range of ecological, social, aesthetic, and health co-benefits. Urban plant covers in particular contribute to improved outdoor environmental conditions that, in turn, influence the energy behavior of buildings and their indoor thermo-hygrometric comfort performance. Within this context, this study illustrates a methodology aimed at verifying the economic feasibility of alternative types of green areas for public and private stakeholders, which are analyzed as passive energy measures. Therefore, our methodology integrates approaches from different disciplines and consists of a microclimatic analysis of different vegetation scenarios…
Informazione floristica e qualità ambientale: analisi delle brioflore di alcune aree verdi dello spazio urbano di Palermo
2006
The results of a study on the bryofloras of three historical gardens (Villa Giulia, Parco d'Orléans and Giardino Garibaldi) and other four smaller green areas (at Niscemi, Stazione Lolli, Castelnuovo e Kalsa squares) of Palermo are provided. These bryofloras (including 65 taxa) are analyzed from the taxonomic, ecological and chorological point of view and compared with Botanical Garden one. Bryofloristic indices, used as instrument of environmental evaluation, show that bryophyte flora of smaller green areas is more affected by building and traffic density of surrounding zone
Giustizia ambientale e recupero delle aree verdi: il caso di Palermo
2021
L’urban shrinkage è diventata una questione centrale tanto nel dibattito scientifico quanto nell’agenda politica di diverse città europee. Secondo i dati EUROSTAT (2019), circa il 40% delle città europee con più di 200.000 abitanti stanno perdendo popolazione; una contrazione che si esplicita maggiormente, sotto il profilo spaziale, in una progressiva sottoutilizzazione del patrimonio edificato, così come nel contestuale incremento di aree e terreni in stato di abbandono. In questo quadro controverso di mutazione strutturale della città, così come l’abbiamo conosciuta, le politiche urbane alla prova in Europa tentano di declinare la decrescita quale occasione strategica di investimento sull…
