Adaptive forest governance to face land use change impacts in Italy: a review
2015
Il cambiamento dell’uso del suolo è uno dei driver principali della riduzione della resilienza ecosistemica, così come della perdita di biodiversità e approvvigionamento di servizi. Rappresenta una sfida peculiare, specialmente negli ambienti mediterranei, dove i fenomeni di abbandono e ricolonizzazione naturale stanno minacciando in modo sempre più crescente la capacità delle foreste di fornire benefici alle comunità locali. In queste condizioni, il sistema di governance forestale è chiamato a bilanciare gli impatti del cambiamento dell’uso del suolo con l’assicurazione della salute e della stabilità degli ecosistemi forestali, al fine di garantire la sostenibilità a lungo termine degli am…
Zastosowanie metodyki audytu krajobrazowego do identyfikacji krajobrazów w skali lokalnej na przykładzie gminy Szczyrk
2018
W artykule przedstawiono wyniki identyfikacji i oceny krajobrazów gminy Szczyrk. W badaniach zastosowano metodę audytu krajobrazowego i trzy kryteria delimitacji: ukształtowanie terenu, kompozycję przestrzenną oraz pokrycie terenu. Badania prowadzono na obszarze górskim, gdzie dotychczas metoda nie była testowana. Stwierdzono występowanie 58 jednostek krajobrazowych należących do 13 typów. Powierzchniowo dominują krajobrazy leśne. Układ jednostek nawiązuje do pięter klimatyczno-roślinnych. Wraz ze zwiększaniem skali badań maleją powierzchnie jednostek, nie maleje znacząco ich liczba. W górach kryterium formy ukształtowania terenu nie wpływa znacząco na liczbę zidentyfikowanych typów krajobr…
Diversità paesaggistica e multifunzionalità dei sistemi agro-forestali dell’Etna
2010
Il paesaggio dell’Etna è un complesso di paesaggi ricchi e diversissimi grazie alla estrema variazione di quote ed esposizioni che da sempre condizionano attività umane e crescita degli organismi; il cono vulcanico etneo rappresenta il principale rilievo e contemporaneamente la formazione geologica più giovane dell’Isola. Tra la fascia basale, maggiormente soggetta ad intesificazioni colturali e quella montana a carattere forestale domina la fascia pedemontana caratterizzata da un’importante valenza paesaggistica e biologica. Allo scopo di prevenire la degradazione o peggio ancora la perdita di questi particolari agroecosistemi è necessario colmare le lacune conoscitive sulla classificazion…
Recognition of earthquake-induced damage in the Abakainon necropolis (NE Sicily): results from geo-morphological, geophysical and numerical analyses
2017
Seismotectonic activity and slope instability are a permanent threat in the archaeological site of Abakainon and in the nearby village of Tripi in NE Sicily. In recent times, signs of an ancient earthquake have been identified in the necropolis of Abakainon which dating was ascertained to the first century AD earthquake. The site is located on a slope of Peloritani Mts. along the Tindari Fault Line and contains evidence for earthquake-induced landslide, including fallen columns and blocks, horizontal shift and counter slope tilting of the tomb basements. In this paper, we used an integrated geomorphological and geophysical analysis to constrain the landslide. The research was directed to th…
Derivation of critical rainfall thresholds for landslide
2016
Rainfall is the primary trigger of shallow landslides that can cause fatalities and economic losses in many areas of the world. For this reason, determining the rainfall amount responsible for landslide occurrence is important, and may contribute to mitigate the related risk. In particular, the definition of critical rainfall-triggering thresholds for landslide is one of the most used approach, which is based on empirical methods. The creation of the rainfall-landslide database represents one of the main efforts in this kind of analysis, which requires a perfect agreement between the rainfall and landslide information in terms of timing. This requirement is easily obtained in the case of th…

ANALYSING RELATIONSHIPS BETWEEN URBAN LAND USE FRAGMENTATION METRICS AND SOCIO-ECONOMIC VARIABLES
2016
Abstract. Analysing urban regions is essential for their correct monitoring and planning. This is mainly accounted for the sharp increase of people living in urban areas, and consequently, the need to manage them. At the same time there has been a rise in the use of spatial and statistical datasets, such as the Urban Atlas, which offers high-resolution urban land use maps obtained from satellite imagery, and the Urban Audit, which provides statistics of European cities and their surroundings. In this study, we analyse the relations between urban fragmentation metrics derived from Land Use and Land Cover (LULC) data from the Urban Atlas dataset, and socio-economic data from the Urban Audit f…
Extremophilic microbial communities on photovoltaic panel surfaces: a two‐year study
2020
Solar panel surfaces can be colonized by microorganisms adapted to desiccation, temperature fluctuations and solar radiation. Although the taxonomic and functional composition of these communities has been studied, the microbial colonization process remains unclear. In the present work, we have monitored this microbial colonization process during 24 months by performing weekly measurements of the photovoltaic efficiency, carrying out 16S rRNA gene high‐throughput sequencing, and studying the effect of antimicrobial compounds on the composition of the microbial biocenosis. This is the first time a long‐term study of the colonization process of solar panels has been performed, and our results…
The summertime Boreal forest field measurement intensive (HUMPPA-COPEC-2010): an overview of meteorological and chemical influences
2011
This paper describes the background, instrumentation, goals, and the regional influences on the HUMPPACOPEC intensive field measurement campaign, conducted at the Boreal forest research station SMEAR II (Station for Measuring Ecosystem-Atmosphere Relation) in Hyyti¨al¨a, Finland from 12 July–12 August 2010. The prevailing meteorological conditions during the campaign are examined and contrasted with those of the past six years. Back trajectory analyses show that meteorological conditions at the site in 2010 were characterized by a higher proportion of southerly flow than in the other years studied. As a result the summer of 2010 was anomalously warm and high in ozone making the campaign rel…
Land surface temperature representativeness in a heterogeneous area through a distributed energy-water balance model and remote sensing data
2010
Land surface temperature is the link between soil-vegetation-atmosphere fluxes and soil water content through the energy water balance. This paper analyses the representativeness of land surface temperature (LST) for a distributed hydrological water balance model (FEST-EWB) using LST from AHS (airborne hyperspectral scanner), with a spatial resolution between 2–4 m, LST from MODIS, with a spatial resolution of 1000 m, and thermal infrared radiometric ground measurements that are compared with the representative equilibrium temperature that closes the energy balance equation in the distributed hydrological model. <br><br> Diurnal and nocturnal images are analyzed due to the non s…
