Studies on sedum taxa found in Sicily (Italy) for mediterranean extensive green roofs

2018

One type of green roof whose function is ecological and environmental rather than aesthetic is the extensive green roof. Many studies have shown that Sedum performs very well compared to other hardy species in substrates of less than 10 cm. It seems that Sedum species are able to survive in very thin substrates; they tolerate extreme temperatures and sudden variations in temperatures, high levels of solar radiation, strong winds, poor substrate fertility and extreme drought. In particular, this paper looks at the potential of a number of species from the Sicilian taxa of the genus Sedum (Crassulaceae), which are considered to be those xerophytes most suited for use in extensive green roof s…

Rosmarino

2009

Il genere Rosmarinus appartiene alla famiglia delle Lamiaceae. Diverse sono le interpretazioni sull’origine del nome del rosmarino. Per molto tempo si è pensato che il nome generico derivasse dal latino “ros” (rugiada) e “marinus” (marino), da cui “rugiada di mare”. Attualmente, gli etimologi sono concordi nel sostenere che la parola rosmarino provenga dal greco “rhos” (arbusto) e “myrinos” (aromatico), da cui “arbusto aromatico”. Questa seconda spiegazione sembra la più convincente in quanto rileva il carattere tipicamente aromatico della specie. Per l’Italia, il Pignatti riporta la specie Rosmarinus officinalis L., che si trova allo stato spontaneo nelle isole e lungo le coste della penis…

Production and energetic performance of Carthamus tinctorius L. in the Mediterranean environment

2012

One of the most important aspects when managing an agro-energy crop is the energy gain factor, that is, the surplus in energy which remains following an appraisal of the relevant inputs and outputs. This aspect is of fundamental importance when choosing a species in a particular growth environment as it gives crucial information on the economic and energetic feasibility of a species and allows us to evaluate potential costs in order to obtain a given production and energy performance. In the agro-energy sector, this indicator is not always included in the evaluation process, making the agronomic and energy results obtained often incomplete. In the Mediterranean area, one potential crop for …

The role of biomass in the production of electricity in agriculture. Current state and development opportunities

2012

The farming sector is currently affected by a continuous fall in the number of people employed in the sector and underemployment in farming families. This is largely due to the world economic crisis and the constant increase in the cost of primary goods coupled with a fall in value of agricultural products. This has caused, in various weak areas of many regions in Italy, a tendency towards rural depopulation with evident signs of land abandonment, leaving the area vulnerable to the risk of hydrogeological instability. It is therefore of the utmost importance to promote activities aimed at diversifying the rural economy by offering incentives to create/increase non-farming activities. Amongs…
