La poesia della terra. Poesia e geografia
2009
recensione al libro di Flavia Cristaldi nella "Rivista Geografica Italiana"
Recensione di La geografia del racconto. Sguardi interdisciplinari sul paesaggio urbano nella narrativa italiana contemporanea, a cura di Davide Papo…
2015
Il volume ha un impianto spiccatamente duale, che riflettendosi sul testo e marcandone la struttura riesce a produrre un confronto serrato nel quale la specificità degli sguardi non si disperde né confonde, alimentando un fitto gioco di rimandi e allacciamenti. L’introduzione, nella versione sdoppiata messa a punto dai curatori, svela pur non tematizzandolo esplicitamente il primo punto di contatto fra i due oriz- zonti disciplinari. Tanto la geografia quanto lo studio della letteratura vengono infatti presentati al lettore come discipline in crisi, attraversate cioè da trasformazioni profonde che ne hanno in tempi recenti messo radicalmente in questione i confini. Ed è proprio a partire da…
Luoghi comuni. Pratiche di reinvenzione urbana ai Cantieri Culturali della ZIsa
2018
L’8 Dicembre 2011 il Comune di Palermo pubblica un “invito a manifestare interesse” verso i Cantieri Culturali alla Zisa, un luogo che da anni versa in grave stato di abbandono. L’invito, rivolto ad imprenditori individuali, società commerciali o cooperative, operatori economici ed altri soggetti privati interessati alla gestione dei padiglioni che compongono il complesso, trova però un destinatario inatteso. Dieci giorni dopo, infatti, un gruppo di artisti, associazioni e liberi cittadini rispondono all’invito del Comune, indicendo tre giornate di assemblee, incontri, performance, proiezioni e dibattiti che riaprissero quello spazio di mezzo che l’opprimente sinergia fra amministrazione pu…
Development of marginal destinations: the case of Menfi
2016
This paper aims to analyse the promotion development of Menfi’s territory. This paper fits the scientific debate about the critical role that Destination marketing and management play in the development of marginal destinations. This paper moves from a geographical approach and, trough a Stake Holders perceptions analysis, wants to emphasise the role of territorial milieu for Menfi’s competitiveness.

Geomorphological, chemical and physical study of “calanchi” landforms in NW Sicily (southern Italy)
2012
Abstract This work deals with an integrated geomorphological and chemical–physical study of “calanchi” landforms in two sites (Ottosalme and Catalfimo) of NW Sicily (southern Italy), developed on dominant silty-clay deposits. The calanchi fronts are characterized by different morphological features and dominant geomorphic processes. Sharp knife-edged ridges and concentrated water runoff dominate at Ottosalme, and smoother landforms affected by mass movements (mud flows and translational slides) prevail at Catalfimo. We focused on some geochemical and physical parameters such as pH , total dissolved salts, sodium adsorption ratio ( SAR ), porosity, plastic and liquid limits as possible cause…
Ground motion phenomena in Caltanissetta (Italy) investigated by InSAR and geological data integration
2008
Urban areas are frequently affected by ground instabilities of various origins. The location of urban zones affected by ground instability phenomena is crucially important for hazard mitigation policies. Satellite-based Interferometric Synthetic Aperture Radar (InSAR) has demonstrated its remarkable capability to detect and quantify ground and building motion in urban areas, especially since the development of Advanced Differential Interferometric SAR techniques (A-DInSAR). In fact, the high density of re.ectors like buildings and infrastructures in urban areas improves the quality of the InSAR signal, allowing sub-centimetric displacements to be reliably detected. The A-DInSAR techniques a…
Some Considerations on 3-D and 2-D Numerical Models for the Assessment of the Stability of Underground Caves
2014
The application of numerical modeling to the analysis of the stability of both natural and man-made underground caves is rapidly increasing due to the availability of powerful numerical codes, that can account for either continuum or discontinuum behavior of the rock masses. Numerical methods allow to overcome traditional methods for cave stability analysis that assume too simplified geometrical, geological and geomechanical conditions. Further, they are also able to assess the potential failure mechanisms of underground systems. On the other hand, the application of numerical methods requires availability of a detailed geo-structural survey of the cave, as well as a proper geomechanical ch…
The Santa Ninfa Cave (Belice Valley): hydrogeochemical features and relationships with neotectonics
2020
The Santa Ninfa Cave (SNC) develops in an outcrop of Messinian gypsum, located in the heart of the zone struck by the 1968 seismic sequence of the Belice valley. It is composed of different levels of sub-horizontal galleries, the lowest of which is characterized by perennial flowing water, running along the water table. From the hydrogeological point of view, it configures as an open circuit, both inflowing and outflowing from/to neighboring aquifers. The geochemical facies of groundwater collected in the SNC is compatible with a meteoric recharge chemically interacting with evaporitic deposits. The most relevant geochemical feature is the mixing between a small tributary of sulfur water wi…
Rockfall hazards of Mount Pellegrino area (Sicily, Southern Italy)
2020
A map derived by rockfall analysis at Mount Pellegrino is presented herein. The study area is affected by several phenomena of rockfall which caused numerous damage and a strong social and economic impact. Official reports and maps that give a general assessment of rockfall hazard are available in this respect, however, it would be advisable to provide a more specific cartographic support useful for land management and planning. The drafting of new maps showing the rockfall runout areas is an additional tool that may be used in conjunction with the existing maps as a means of risk mitigation and reduction. On the basis of geological, geomorphological, and geomechanical analysis and exploiti…
