The agricultural heritage of Lampedusa (Pelagie Archipelago, South Italy) and its key role for cultivar and wildlife conservation
2011
As occurred on many other little Mediterranean islands, agricultural activity at Lampedusa (Strait of Sicily) underwent a very strong decline in terms of surface area during the second half of the last century. In particular, cereal crops have ceased and horticulture is disappearing, while vineyards still occupy a reduced area but are quickly vanishing and currently survive thanks to a small number of old farmers. Here are presented the results of a research carried out by interviewing seven farmers in order to study not only the techniques and the germplasm used in local viticulture, but also the final use of grapes and an evaluation on the connection between traditional farming and agro-e…
Study of energetic properties of different tree organs in six Olea europaea L. cultivars
2021
AbstractPruning is an important horticultural practice for the management of olive orchards (Olea europaea L.) that generates a considerable amount of residues every year. Olive orchards are increasingly expanding beyond the Mediterranean Basin to new growing Countries (Australia, California, Argentina, Chile and Uruguay) and this will certainly lead to larger availability of pruning material. Currently, the interest in use of olive tree pruning residues for energy purposes is increasing but unfortunately, the information on the differences among organs of the tree, in terms of calorific value and ash content, is scarce. Another unknown aspect is the effect of cultivar vigour on dry matter …
L’utilizzo di specie alloctone invasive per la produzione di legno: rischio o opportunità?
2017
L’arboricoltura da legno, così come l’attività di rimboschimento propriamente detta, ha da sempre fatto ricorso anche a specie estranee alla flora locale, che si sono spesso rivelate particolarmente adatte a questo scopo. Tali scelte sono state principalmente legate alla notevole rapidità di crescita iniziale di alcune specie alloctone rispetto a quelle autoctone, e quindi alla possibilità di ottenere un’elevata produzione legnosa in tempi brevi, carattere fondamentale soprattutto nel caso di impianti realizzati a fini energetici. Tuttavia, in conseguenza della mancata valutazione dell’effettiva idoneità ecologica delle aree di impianto, spesso gli impianti non hanno raggiunto livelli produ…
1° Convegno Nazionale Alberi Monumentali - Conoscenza, Conservazione, Valorizzazione - Riassunti Relazioni e Poster
2016
Dal 18 al 19 giugno 2016, nei territori del Parco dei Nebrodi (Santo Stefano di Camastra) e del Parco delle Madonie (Castelbuono), è stato organizzato il primo convegno nazionale sugli alberi monumentali. Il convegno è stato promosso dal Parco dei Nebrodi, dall’Università di Palermo (C.I.R.I.T.A. e Dipartimento SAF), dal Parco delle Madonie, dal Dipartimento Regionale dello Sviluppo Rurale e Territoriale, dalla Fondazione Ecosistemi - Roma, da D.B.I. srl Bagheria, dal GAL Natiblei, dall’Istituto Idimed e dal Corpo Forestale della Regione Siciliana. Il convegno è stato rivolto in particolar modo agli studiosi del settore, ai tecnici (agronomi, forestali, architetti, biologi, naturalisti, ecc…
Sustainable management systems to prevent and adaptat to desertification: Case Studies from the LIFE Desert Adapt project
2021
Around 40% of the ice-free terrestrial surface is under desertification risk, and the Mediterranean is one of the most sensible regions. Concomitantly, most areas occupied by agriculture suffer from lack of organic matter in the soil, as well as very low tree cover, making them more vulnerable to climate change. The LIFE (Desert Adapt) project aims to develop a desert adaptation model to enhance resistence and resilience of farms, both public and private, to desertification by appliyng an integrative sustainable land management in Italy, Spain and Portugal. In Italy three sites in Sicily are involved, two private areas in Caltanissetta and Catagirone and the municiaplity of Lampedusa.The mo…
Evaluation of benefits and limitations of a Desertification Adaptation Model framework for sustainable land management in areas under desertification…
2022
The LIFE project Desert-Adapt (LIFE16 CCA/IT/000011) has designed a Desertification Adaptation Model (DAM) framework of land management to respond to two of the most critical problems experienced by farmers, public land and communities of the Mediterranean Basin, given the need to adapt to current Climate Change and reduce or counteract the increasing phenomenon of land degradation and desertification risk. These two issues are interrelated, as land degradation often characterizes fragile areas where the co-occurrence of climatically unfavourable conditions, mostly prolonged aridity and high temperatures, and inappropriate land management, leads to loss of ecosystem quality, biodiversity, p…
Study of green Sicilian table olive fermentations through microbiological, chemical and sensory analyses.
2010
The production of five different green table olive cultivars was studied by a combined strategy consisting of chemical, microbiological and sensory analyses. Cultivable microflora of samples collected during processing was monitored by plate counts on seven synthetic culture media. In all samples Enterobacteriaceae, Pseudomonaceae, staphylococci, lactic acid bacteria and spore-forming bacteria were undetectable. Yeasts and moulds were countable from the day 42 (2 log CFU/ml) till the end of fermentation (6 log CFU/ml). The use of three different approaches for microorganism detection, including a culture-independent methodology, revealed the presence of barely three yeast species during the…
uality Evaluation of “Tardivo di Ciaculli” Mandarins in Post-Harvest Processing on an Industrial Scale Using a Portable Vis/NIR Device
2016
Abstract. Vis/NIR technology is widely used today to quickly and non-destructively evaluate fruit and vegetable qualities, and many applications have been found since the 1990s. However, no industrial-scale applications can further consolidate the use of non-destructive techniques in post-harvest processing. This study aims to test the possibility of applying vis/NIR technology in a modern citrus-processing plant to assess the damage that the fruits eventually suffer when they are processed on an industrial scale and the evolution of their key quality parameters in a period of 10 days after harvest. The spectral acquisitions were performed using a portable vis/NIR device, which operated in …
PBAT Based Composites Reinforced with Microcrystalline Cellulose Obtained from Softwood Almond Shells
2021
This study explores the processability, mechanical, and thermal properties of biocompostable composites based on poly (butylene adipate-co-terephthalate) (PBAT) as polymer matrix and microcrystalline cellulose (MCC) derived from softwood almond (Prunus dulcis) shells (as-MCC) as filler at two different weight concentration, i.e., 10 wt% and 20 wt%. The materials were processed by melt mixing and a commercial MCC (c-MCC) was used as filler comparison. The fibrillar shape of as-MCC particles was found to change the rheological behavior of PBAT, particularly at the highest concentration. The melt mixing processing allowed obtaining a uniform dispersion of both kinds of fillers, slightly reduci…
Perspectives of the encapsulation technology in the nursery activity of Citrus
2007
The genetic and phytosanitary certification has to guarantee the quality of the propagation material also in Citrus. Traditional methods can be assisted by the techniques of in vitro culture, which are fundamental for the mass production of high quality plants. The encapsulation technology represents an innovative tool to combine the advantages of micropropagation with handling ease, storability, reduced size of the propagules, mechanization potentiality, transportability of the gamic seeds. In this work somatic embryos obtained from in vitro anther culture of the cultivar Mandarino Tardivo di Ciaculli (Citrus reticulata Blanco) were encapsulated in a sodium alginate matrix and synthetic se…
