This study provides a preliminary agro-environmental, economic and energetic analysis to critically evaluate the biomass potential ofan area of central Italy (Tuscia Romana). This area is selected as representative foragro-forestry from its orographic characteristics, climatic conditions, land use and potential energy sources. Accordingly, the model we have obtained could be used forother similar areasof central Italy. We have assessed the potential agro-forestry biomass availability, energy potential and transport infrastructure using multi criteria analysisand geographic information system approaches. Finally,optimum locations to develop an energy plant were identified. This model could be applied at alocal levelto help deliver environmental policy.
A comprehensive temporal analysis of precipitation and temperature regimes from 1951 to 2010 has been carried out at a national and regional scale in Italy to investigate the impact of climate aridity on the agricultural system. Trends in climate aridity have also been analyzed using the UNEP aridity index, which is the ratio of rainfall to reference evapotranspiration on a yearly basis. During the time period examined, and particularly in the most recent years, a gradual reduction in rainfall and increase in temperature have been observed, which further widened the gap between precipitation and agricultural water demand
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
