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…

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…

Urban shrinkage became a central issue in both the scientific debate and the political agenda of several European cities. According to EUROSTAT data (2019) about 40% of European cities with more than 200000 inhabitants are losing population. A shrinkage that is more explicit in a progressive underutilization of the built heritage as well as in the concomitant increase of abandoned areas. In this controversial framework of structural mutation of the city urban policies in Europe try to decline the degrowth as a strategic opportunity to invest in green areas in order to increase urban quality and to act simultaneously on the development of local economies. With respect to the above framework this contribution focuses on the evaluation of the effects that the project of new public green spaces have generated on some sample areas on the outskirts of the city of Palermo. An urban context where according to the latest Svimez Report (2019) the phenomenon of urban shrinkage represents a constantly growing trend and on which the new Master Plan operates through a revival of interventions on environmental capital and urban green areas of the city.Settore ICAR/21 - Urbanistica
