Analisi sistemica del paesaggio agrario tradizionale dell’albero in ambiente mediterraneo
2010
Il paesaggio coltivato dell’albero rappresenta una fisionomia distintiva di vaste aree territoriali italiane, dalle zone di montagna a quelle costiere. Le diverse tipologie di coltivazioni agrarie arboree si sono evolute rapidamente negli ultimi decenni in termini di assortimenti varietali e di modelli di impianto, portando ad una specializzazione e polarizzazione delle coltivazioni nelle aree a maggiore vocazione produttiva e gestibili con maggiore sostenibilità ambientale e economica. I paesaggi agrari tradizionali (PAT) dell’albero rappresentano, di contro, delle realtà residuali e resilienti a cui vengono riconosciuti funzioni multiple e valori complessi. Scopo della ricerca è stata l’a…
The Viticulture of Lampedusa, a heritage which is disappearing before being known.
2010
The study is focused on the viticulture of the island of Lampedusa, located in the strait of Sicily 113 km from the African coast and 205 km from the Sicilian coasts. It is a study that has no previous recorded documentations. The research was conducted on the island to a various number of vineyard farmers in order to describe cultivation techniques and the grape germplasm utilized. Viticulture is present on several tens of hectares but in recent years is vanishing quickly and currently survives thanks to a small number of old farmers who still practice agriculture. Moreover, the strong competition for land use strongly linked to tourism, makes the survival of farming in general even more p…

Il ruolo delle precipitazioni occulte nella formazione e mantenimento della vegetazione forestale: il caso studio di Pantelleria
2019
Le testimonianze storiche indicano per le isole circumsiciliane la presenza di floridi boschi che sono stati distrutti a seguito dei processi di deforestazione. In alcuni casi, dopo gli interventi di rimboschimento, la vegetazione riesce a ricostituirsi con difficoltà come a Lampedusa mentre in altri casi i processi di recupero sono molto rapidi. Un ruolo non indifferente viene svolto dalla presenza di piante in grado di diffondere propaguli ma anche dalle condizioni climatiche locali determinate sia dalla morfologia delle singole isole come, ad esempio, la presenza di rilievi montuosi, che dal particolare contesto oceanografico. I dati medi riportati dalle stazioni climatiche in termini di…
First assessment of natural regeneration and seed dispersal of Persian walnut (Juglans regia L.) in Mediterranean agroecosystems
2020
Persian walnut (Juglans regia L.), which is native to Central Asia, has been widely cultivated throughout Europe over millennia as a multipurpose tree. However, only recently the naturalization process outside cultivation has been studied, mostly in temperate Europe, with no information regarding the Mediterranean region. Here we provide the first field investigations about the natural regeneration of walnut in two traditional Mediterranean agroecosystems: an irrigated mixed orchard in suburban areas and a non-irrigated prickly pear (Opuntia ficusindica [L.] Mill.) orchard. The natural regeneration densities were statistically different in the two agroecosystems, ranging from 75 individuals…
The role of loquat to maintain entomological diversity in the Conca d'Oro orchards
2014
The loquat [Eriobotryo japonica (Thumb.) Lindl.] is an allochthonous species long cultivated in Sicily. In some parts of Sicily such as the Siracusa province, the loquat is cultivated in mono-specific orchards. In other sites, like Conca d'Oro and other places near the town of Palermo, loquat is intercropped with other tree species such as citrus, apricot, peach, mulberry, walnut, Mediterranean hackberry. The loquat plays an important role in order to increase biodiversity within these orchards. The old or dead loquat trees host a variety of xylophagous insects and more in particular Coleoptera: Cerambycidae beetles Dynastidae, and Cetoniidae. Longhorn beetles, rhinoceros beetles and flower…

Lost in space? Using geo-narratives to interpret land use changes in a rural landscape of inner Sicily
2021
Intercropping landscapes characterised by the presence of certain plant features (i.e. old-century olive trees) are usually considered traditional landscapes, extremely important for their biocultural heritage. Olive agroforestry systems were widespread in the past throughout Sicily. Recent evolution processes involving intensification have switched to olive grove monocultures. Here we present ongoing work on the application of geo-narratives to interpret transformation dynamics of land use practices in a rural landscape of inner Sicily. Based on the assumption that spatial patterns are the expression of transformation processes, where the spatial variation of human activities is a signific…
IoT monitoring of urban tree ecosystem services: Possibilities and challenges
2020
Urban green infrastructure plays an increasingly significant role in sustainable urban development planning as it provides important regulating and cultural ecosystem services. Monitoring of such dynamic and complex systems requires technological solutions which provide easy data collection, processing, and utilization at affordable costs. To meet these challenges a pilot study was conducted using a network of wireless, low cost, and multiparameter monitoring devices, which operate using Internet of Things (IoT) technology, to provide real-time monitoring of regulatory ecosystem services in the form of meaningful indicators for both human health and environmental policies. The pilot study w…
Quali formazioni boschive in un clima più caldo?
2016
La plurimillenaria azione dell'uomo sugli ecosistemi sudalpini, e mediterranei in particolare, ha fortemente alterato i consorzi vegetali e spesso cancellato le specie arboree che in natura dominerebbero nelle attuali condizioni ambientali. Tale lacuna rende molto difficile pronosticare quali specie sarebbero le meglio adattate a eventuali futuri cambiamenti climatici.
