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.
Which are Southern Italy’s fastest growing tree species? Lessons from the past for future perspectives, with a special focus on Sicily
2020
Fast growing tree species can generate high wood production in a short time frame. However, maximum productivity is dependent on environmental and management conditions as well as intrinsic plant traits. Within this framework, our research was into tree species with the highest Mean Annual Increments (MAIs) in southern Italy, particularly in Sicily. Eucalyptus spp., Acacia saligna (Labill.) H. L. Wendl., Ailanthus altissima Mill. (Swingle), Pinus halepensis Mill. (including Pinus brutia Ten.), Pinus canariensis C.Sm. and Pinus radiata D. Don. were identified. In particularly suitable conditions, the MAI of eucalypt coppices ranged from 8 to 12 m3 ha-1, and from 13 to 19 m3 ha-1, in Eucalypt…
The use of species in plantations: renaturalisation and reforestation in Sicily
2017
Afforestation and reforestation activities in Sicily have been widespread in the last century, in order to increase the forest cover that was seriously reduced in the former centuries. Notwithstanding this, Sicily is still characterized by only the 12% of the regional surface covered by woods and forest. The reforestation in the last century was carried out using conifers and eucalypts, just in order to ensure a quick protection of slopes and pastureland, coping diffuse erosion events, and those intervention had a remarkable success. Nowadays, the target of enlarging the forest areas in the island is still compulsive, but the use of species, considering the actual knowledge and nature consc…
I patriarchi verdi dei Monti Sicani
2016
Gli alberi vetusti costituiscono un segno della capacità e plasticità di adattamento di alcune specie ma sono anche spesso frutto del caso o di una considerazione particolare da parte di alcune comunità locali rispetto ad alcune piante. Sui Monti Sicani, situati nel settore centro-occidentale della Sicilia, si rileva la presenza di numerosi alberi monumentali, la cui conservazione è stata assicurata, nonostante le trasformazioni del paesaggio avvenute nel corso di un lunghissimo periodo, dalla positiva influenza delle conoscenze, tradizioni e buone pratiche delle popolazioni locali (De Gregorio, 2008). Tuttavia, ad eccezione del censimento dei grandi alberi di Sicilia (Schicchi e Raimondo, …
