Gli interventi per lo sviluppo locale all'interno delle Regioni ad autonomia speciale
2022
Il tema dello sviluppo locale interessa in modo particolare le aree marginali. Se queste sono dal punto di vista giuridico autonomie speciali si pongono all’analisi dinamiche e sviluppi che meritano una particolare attenzione. È questo il caso delle tre realtà regionali che saranno prese in esame: Valle d’Aosta, Sardegna e Sicilia. Interventions for local development within special self-governing regions. The issue of local development is of particular interest to marginal areas. If these are from a legal point of view, special autonomies arise from the analysis of dynamics and developments that deserve particular attention. This is the case of the three regional realities that will be exam…
Lo spazio bergmaniano ne Il posto delle fragole
2016
Una delle prerogative della Geografia è quella di essere spiegata e illustrata agli allievi attraverso molteplici strumenti a disposizione del docente. Uno di questi strumenti è la visione di un opera filmica o di parte di essa. La proposta didattica di questo contributo riguarda la visione di un opera del regista svedese Ingmar Bergman al fine di discutere principalmente del significato del concetto di luogo. One of the opportunities of Geography is to be explained and illustrated to students through various resources available to the teacher. One such tool is the vision of a movie or part of it. This paper is the outcome of a didactic proposal for students regarding the vision of a film o…
SEA LEVEL CHANGES DURING THE HOLOCENE IN MALTA AND BARI, CENTRAL MEDITERRANEAN
2012
During the last decade several papers have been published to estimate the relative sea-level change from coastal archaeological indicators in many locations of the Italian coasts and the Mediter-ranean Sea. Anyway, the use of the archaeological information has been poorly focused for Middle Ages and the Bronze Age, due to a few of available coastal installations for these periods. In this paper, we focus on two areas of the Mediterranean, namely the coasts of Malta island and Bari, in Apulia (Southern Italy), that displays coastal archaeological markers of the Bronze age and Middle ages, respectively. The elevation of the selected markers were compared against the latest model prediction of…
Dendrolatrie della scia. Corpi arborei e semi della memoria
2021
Invisibilizzazione, disumanizzazione, dolore del trauma, naufragio: la scia si produce e si riproduce in mare, in un attraversamento in cui il Mediterraneo diviene eco dell’Atlantico e viceversa. Centrale per questo riecheggiare è la memoria. La memoria di un passato che non è mai passato, che torna a fratturare il presente e continua a riprodursi in un tempo circolare della schiavitù, inteso come futuro creato da essa (Hartman 2007). E la creazione del futuro passa per la coltivazione dei semi della memoria: semi in movimento, che creano così una trama filiforme che unisce l’Atlantico Nero al Mediterraneo Nero. Depositari del passato e base per la creazione del futuro, i semi della memoria…
Tidal notches, coastal landforms and relative sea-level changes during the Late Quaternary at Ustica Island (Tyrrhenian Sea, Italy)
2017
In this paper we present and discuss data concerning the morphostructural evolution at Ustica Island (Tyrrhenian Sea, Italy) during Late Quaternary. New insights on the relative sea-level changes of Ustica are coming from data collected during a geomorphological field survey around the island, together with the bathymetric analysis of the surrounding seabed and 14C datings on samples of speleothems, flowstones and marine shells found inside three selected sea caves. The survey was mainly accomplished on June 2015 through the first complete snorkel investigation off the about 18 km-long volcanic coast of the island, which allowed to precisely define location, relationship and morphometric fe…
Morphometric and hydraulic geometry assessment of a gully in SW Spain
2016
Abstract Gully erosion represents one of the most significant types of land degradation in the Mediterranean areas, giving place to important on- and off-site effects. In this paper, a second-order gully located in SW Spain is analyzed. Along the gully, 28 cross-sections were established and measured with a Leica TCRM1102 laser total station, approximately every 6 months from 2001 to 2007. The sections were located at variable distance, placing them in areas where active erosion was evident. In total, 13 field measurements were carried out, and the geometric characteristics of 28 cross-sections were obtained. Morphometric analyses were carried out in both the main gully and a tributary reac…
Geomorphology of the Anthropocene in Mediterranean urban areas
2019
Urban-geomorphology studies in historical cities provide a significant contribution towards the broad definition of the Anthropocene, perhaps even including its consideration as a new unit of geological time. Specific methodological approaches to recognize and map landforms in urban environments, where human-induced geomorphic processes have often overcome the natural ones, are proposed. This paper reports the results from, and comparison of, studies conducted in coastal historical cities facing the core of the Mediterranean Sea – that is, Genoa, Rome, Naples, Palermo (Italy) and Patras (Greece). Their settlements were facilitated by similar climatic and geographical contexts, with high gr…
Multi-method evaluation of denudation rates in small mediterranean catchments
2015
The paper presents the results of the research tasks of the Quantitative Geomorphology Working Group (of the Italian Association of Physical Geography and Geomorphology) focused on multi-method evaluation of denudation rates in small catchments of Italy. Several study areas are compared with the goal of quantifying the morphodynamic evolution in different response times and with traditional and innovative techniques. The final aims are the direct erosion monitoring, the geomorphic analysis for the comprehension of drainage basin morphodynamics, up to the geomorphological hazard evaluation. The catchments are key Mediterranean areas particularly sensitive to climatic and anthropic modificati…
Human settlements in the Mediterranean and the sea level changes from 12 ka to the present
2012
Understanding past sea-level change plays an important role in determining the underlying causes, and also allows the extrapolation of past sea levels to locations and epochs for which there are no instrumental data. A compilation of global sea-level estimates based on deep-sea oxygen isotope ratios at millennial-scale resolution or higher was published since ‘70. These global sea level curves do not take in account isostasy and tectonics. Observed sea level change can be reconstructed from dated fossils, coral reef terraces, speleothems, emerged and forming terraces on coastal areas, archaeological and other markers well connected with sea level. Because of the lack of coral reefs in the M…
Relationships between a new slope morphometric index and calanchi erosion in northern Sicily, Italy
2012
The Italian badlands, or “calanchi”, are common landforms in Mediterranean areas including central and southern Italy. Calanchi landforms may be compared to small hydrographic basins. These landforms are characterised by dense, hierarchical and rapidly evolving drainage systems carved into steep clayey slopes and by a sharply alternating pattern of furrows and narrow, generally sharp crests. This work presents a study of morphometric characteristics and a statistical analysis for two sites in northern Sicily (Italy), on outcrops of silty-clay deposits affected by active erosion processes, which give this area a typical calanchi landscape. In particular, factors closely linked to the charact…
