La vulnerabilità alla desertificazione della Sicilia
2009
Città e deserto. Appunti di un viaggio in Giordania. City and desert. Notes from a journey in Jordan
2012
The book is the result of some thoughts that I have gained during my stay in Jordan, where, for a few years, I have been teaching and researching, following an intense exchange activities developed productively thanks to the cooperation agreements between the University of Palermo, the University of Jordan in Amman and Al al-Bayt University of Mafraq.
La vulnerabilitè alla desertificazione della Sicilia
2009
Viene applicata una nuova metodologia che,i cui criteri di analisi vengono illustrati,che può essere considerata un'implementazione del modello DESERT e può costituire un supporto tecnico scientifico per il monitoraggio e la programmazione degli interventi nelle aree identificate a rischio desertificazione.

Defining minimum runoff length allows for discriminating biocrusts and rainfall events
2021
This study was started in the context of the research projects PECOS (REN2003-04570/GLO) and PREVEA (CGL2007-63258/BOS) , both funded by the Spanish National Plan for RD&I and by the European ERDF Funds (European Regional Development Fund) , and continued during the project SCIN (Soil Crust In-terNational, PRI-PIMBDV-2011-0874, European project of ERA-NET BIODIVERSA, the Spanish team being funded by the Spanish Ministry of Economy and Competitiveness) . The work was finally supported and culminated by the DINCOS project (CGL2016-78075-P, Spanish State Programme for Scientific Research) and by the European ERDF Funds (Euro-pean Regional Development Fund) . Consuelo Rubio's partici-pation was…

Effects of Biochar on Irrigation Management and Water Use Efficiency for Three Different Crops in a Desert Sandy Soil
2020
This paper aimed at investigating if the application of biochar (BC) to desert sand (DS) from the United Arab Emirates (UAE), characterized by a very poor soil-water retention (SWR) and by a very low value of the maximum water available for crops (AWmax), could positively affect soil water balance, by reducing the irrigation needs (VIRR) and improving the irrigation water use efficiency (IWUE) and the water use efficiency (WUE). The analysis was performed for three crops, i.e., wheat (Triticum aestivum), sorghum (Sorghum vulgare) and tomato (Lycopersicon esculentum). BC was applied to the DS at different fractions, fBC (fBC = 0, 0.091, 0.23 and 0.33). Drip irrigation was adopted as a highly…

Rimboschimenti e lotta alla desertificazione In Italia
2009
Questa monografia propone una lettura critica sul ruolo attuale del rimboschimento nella prevenzione e mitigazione dei processi di desertificazione in Italia. Le potenzialità del rimboschimento sono inquadrate in una prospettiva multifunzionale e sinergica che comprende le ricadute ambientali di questa attività anche in termini di assorbimento del carbonio atmosferico e potenziamento della biodiversità, oltre che di conservazione del suolo e recupero e riqualificazione di paesaggi degradati. L’obiettivo è delineare una strategia di lotta alla desertificazione applicabile a livello regionale, nel quadro degli strumenti programmatici e di governo del territorio rurale e fornire orientamenti t…
Effect of Chitin Whiskers on the Molecular Dynamics of Carrageenan-Based Nanocomposites
2019
[EN] Films of carrageenan (KC) and glycerol (g) with different contents of chitin nanowhiskers (CHW) were prepared by a solution casting process. The molecular dynamics of pure carrageenan (KC), carrageenan/glycerol (KCg) and KCg with different quantities of CHWs as a filler was studied using dielectric relaxation spectroscopy. The analysis of the CHW effect on the molecular mobility at the glass transition, T-g, indicates that non-attractive intermolecular interactions between KCg and CHW occur. The fragility index increased upon CHW incorporation, due to a reduction in the polymer chains mobility produced by the CHW confinement of the KCg network. The apparent activation energy associated…
