Assessment of agricultural production sustainability is a multi-dimensional task that involves the quantification of various economic,social and environmental indicators at different scales and uncertainty *** this context,a particularly challenging approach is proposed involving the appropriate selection of the most representative criteria that ensure economic viability,eco-friendliness and social development,in order to overcome the limitations of other methodological approaches that are often vague and *** this study,a holistic methodology that integrates life cycle analysis(LCA),environmental risk assessment(ERA)along with on-site farm and regional surveys using the multi-criteria environment of the Analytical Hierarchy Process(AHP)is designed for the identification of the most sustainable agricultural management practices at regional *** on a set of 13 representative sub-criteria,the proposed approach was applied to Pistacia vera *** in Aegina island,Greece,where narrow range of resources is available,groundwater supply is scarce and of poor ***,three alternative scenarios,*** scenario representing the current production(BL)as well as Composting(CO)and Biochar Use(BU)scenarios aiming at sustainability improvement were *** of multi-criteria and sensitivity analyses suggest that the optimal sustainable management scenario is CΟ,which involves on-site composting of organic solid waste,mainly produced at farm site,and subsequent application in the *** proposed methodology shows significant potential as a valuable multi-criteria tool that can be easily adapted at regional level to assist decision makers such as farmers and their associations,policy makers,local and regional authorities to efficiently explore a range of alternative farm management practices and thus identify pathways toward sustainability.

In the present paper,a life cycle assessment(LCA)study regarding barley and lettuce production in Spain(Barrax and Santomera regions)and Italy(Albenga region)in both open field(OF)and standard greenhouse(GH)cultivations was performed in order to evaluate energy consumption and environmental *** study examines also the impact of the use of compost produced from agricultural wastes(AW).In this context,a detailed life cycle directory was created,based on site-specific experimental data,and used for a holistic cradle-to-gate LCA analysis using the GaBi 6 software package and specific related *** order to reveal the importance of system boundaries,factors that are often excluded from LCA studies,such as agricultural machinery manufacture,nursery production,waste management and raw materials transportation have been *** to the results of this study,the use of compost for fertilization of both crops is considered a good agronomic and ecological strategy in order to maintain productivity in terms of yield,especially in the case of greenhouse cultivation,and improve overall sustainability in the agricultural ***,the phases of compost production,irrigation system,and greenhouse construction and operation were identified as the three main‘‘hotspots”with the highest environmental impact and energy contribution in all studied ***,improvements to reduce those impacts were proposed.

In the present study a specific approach is followed,considering the Pesticide DRASTIC and Susceptibility index(SI)methods and a GIS framework,to assess groundwater vulnerability in the agricultural area of Albenga,in north *** results indicate"high"to"very high"vulnerability to groundwater contamination along the coastline and the middle part of the Albenga plain,for almost 49%and 56%of the total study area for Pesticide DRASTIC and SI methods,*** sensitive regions depict characteristics such as shallow depth to groundwater,extensive deposits of alluvial silty clays,flat topography and intensive agricultural *** distribution of nitrates concentration in groundwater in the study area is slightly better correlated with the SI(0.728)compared to Pesticide DRASTIC(0.693),thus indicating that both methods are characterized by quite good *** analysis was also performed to acknowledge statistical uncertainty in the estimation of each parameter used,assess its impact and thus identify the most critical parameters that require further investigation in the *** to water is the parameter that exhibited the largest impact on the Pesticide DRASTIC vulnerability index followed by the impact of the vadose zone and *** the other hand,the SI method is more sensitive to the removal of the topography parameter followed by the aquifer media and the depth to water parameters.
