Gestione sostenibile delle foreste Mediterranee e uso energetico delle biomasse forestali residuali
2014
he book describes the reasons that led the Regional Department of Rural and Territorial Development to take part in the PROFORBIOMED Project. They can be summarized by the need to dispose of a tool for the sustainable management of all the state-owned forests of the Region. As a matter of fact, the Project aims at developing a model of sustainable forest management, through the recovery and reuse of wood scraps from ordinary silvicultural operations, to be used for the production of power and heat inside of a process adopting natural renewable energy sources. The main actions taken and the methodologies adopted are described, as well as the principles and instruments required for the settin…

Nuovi dati sulla nidificazione del rigogolo Oriolus oriolus (L.) (Aves Oriolidae) in Sicilia

Linee guida per la valutazione della resilienza delle foreste Mediterranee ai cambiamenti climatici [Guidelines for assessing the resilience of Medit…

We have defined optimal management models for improving or strengthening the resilience of forest environments: in particular, five best management practices aiming at improving the Mediterranean forests resilience with reference to the desertification risk. The 5 Best ManagementPractices are: BMP1 - Actions favoring mixing of species and hydrogeological stability of forests; BMP2 - Renaturalization of forest plantations; BMP3 - Remedial measures and restoration of degraded forests; BMP4 - Actions aimed at enhancing complex structural forests; BMP5 - Actions favoring connectivity in agro-forestry systems. The best management practices have been then applied adapting them to 16 different int…
Brevi considerazioni su piogge intense e potenzialità di produzione del deflusso superficiale in Sicilia
2013
Vengono presentati i metodi aggiornati per la stima delle precipitazioni intense massime annue di fissato tempo di ritorno in Sicilia. Dall‟osservazione della distribuzione spaziale dei parametri assunti nei modelli di stima emergono aree a maggior rischio riguardo l‟intensità di pioggia, qui commentate. Il richiamo a recenti studi che riguardano la produzione del deflusso superficiale a scala media annua o a scala di evento, consente di avanzare alcune considerazioni di tipo spaziale, con particolare attenzione all‟area del messinese, su questa importante propensione idrologica notoriamente fonte di dissesto idrogeologico e di pericolo alluvionale. The updated methods for the estimation of…
Castelporziano: una smart forest
2015
Il Consiglio per la Ricerca in Agricoltura (CRA) – con la sua Unità di Ricerca per il Monitoraggio e la Pianificazione Forestale di Trento – in collaborazione con la società di spin-off del CRA “EFFETRESEIZERO” Srl (specializzata in geomatica e informatica forestale) ha messo a punto uno strumento informatizzato “geografico” innovativo, per descrivere e quantificare minuziosamente il patrimonio boschivo della Tenuta Presidenziale di Castelporziano al 2014.
Assessing Hydrus-2D model to investigate the effects of different on-farm irrigation strategies on potato crop under subsurface drip irrigation
2019
The objective of this paper was to assess the performance of Hydrus-2D model to simulate the effects of different on-farm irrigation strategies applied on potato crop. The ability of the model to simulate the stress coefficient (Ks), obtained as the ratio between actual and maximum transpiration, and to define the productive function of potato crop under the semi-arid conditions of central Tunisia were also evaluated. Experiments were carried out on potato crop under full (FI) and deficit irrigation (DI) and two different water qualities supplied by means of a subsurface drip irrigation system. Results evidenced that the model, despite some discrepancies locally observed, can fairly accurat…
Morphometric characterization of a calanchi inventory in Sicily, Italy
2015
Calanchi are a frequent type of badland landscape of Sicily (Italy), usually located in the middle of crops or forests. They are characterized by heavily dissected terrains with unvegetated slopes, knife ridge edges, V-shaped valleys and channels with a dendritic pattern, which incise and extend headwards. Calanchi exhibit, in smaller temporal and spatial scales, many of the geomorphic processes and landforms that may by observed in a fluvial landscape, hence, this type of badland may be considered as micro-watersheds where geomorphic dynamics can be related to their geometric features. The aim of this investigation was to evaluate the morphometric characteristics of calanchi landforms in S…
Ability of soil bacterial composition as an indicator of levels of soil erosion in a badland
2022
Calanchi (plural of calanco) are typical Italian badlands created by a combination of morphogenetic processes (rill and interrill erosion, gullying, piping, and mass movements) mainly originated by the effect of water. Calanchi are characterized by the sparse and patchy distribution of vegetation, and, in interplant areas, the soil surface is colonized by an association of organisms known as biological soil crust (BSC). A morphometric analysis of 45 basins in the studied calanchi area, based on a high-resolution digital elevation model, showed those basins are sediment removal systems characterized by rapid and relevant erosion processes. The goal of the current research is to evaluate the …
