Abstract:The wine sector is going through a significant evolution dealing with the challenges of competition issues in international markets and with necessary commitments to sustainability improvement. In the wine supply chain, the agricultural phase represents a potential source of pollution and costs. From the farmers' point of view, these contexts require them to be more attentive and find a compromise among environmental benefits, economic benefits, and costs linked to farming practices. This paper aims to make a sustainability assessment of different wine-growing scenarios located in Calabria (Southern Italy) that combines conflicting insights, i.e., environmental and economic ones, by applying Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) to identify the main hotspots and select the alternative scenarios closest to the ideal solution through the VIKOR multicriteria method. In particular, the latter allowed us to obtain synthetic indices for a two-dimensional sustainability assessment. Conventional practices associated to the espalier training system represent the best compromise from both environmental and economic points of view, due to the higher yield per hectare. The choices regarding Functional Unit (FU) and indicators were shown to have a high influence on results.

The low resilience of ecosystems imposes a sustainable management of natural resources through more rational uses, land protection, energy saving and low carbon production technologies. Agriculture has a great responsibility in managing these resources that are the principal inputs of its processes. Production systems must pay attention, at the same time, to economic viability and environmental protection. Since decades, the international scientific community is facing the great challenge of assessing the sustainability of agricultural engineering techniques, in order to help both private and public decision making, but also to meet consumer's requirements for high quality and low impact products. To achieve that, widely accepted assessment instruments, whose results have to be clear and understandable to a broad public, and that are necessary. In this direction, Life Cycle Thinking (LCT) is gaining consensus as conceptual model, considering goods and services production and consumption all along the whole life cycle, from planning to disposal. Its methodological frame-work, the Life Cycle Management (LCM), offers many standardised tools to assess impacts of products and processes: Life Cycle Assessment (LCA), to evaluate environmental impacts and Life Cycle Costing (LCC) for economic ones. Among many impacts categories LCA also allows to identify the carbon footprint, that can be quantified in terms of Global Warming Potential (GWP). This re-search has analyzed and compared different scenarios of wine grapes production in Cirò, an important viticultural area located in Calabria region (Southern Italy). LCA and LCC methodologies have been useful to assess them from an environmental and economic standpoint. Results have allowed the authors to rank training and farming systems performances.

Farming systems need to be planned to provide suitable levels of economic profitability and, at the same time, ensure an effective energy use, in order to perform environmentally friendly production strategies. The herein present work aims to assess the efficiency of energy use and economic impacts of the main farming methods (conventional, organic and integrated) of Clementine’s crops in Calabria (South Italy), through a combined use of Life Cycle Energy Assessment (LCEA) approach and economic analysis. For this purpose, data were collected from clementine producers by using face-to-face interviews. The results revealed that average energy consumption in the organic farming systems was 72,739 MJ, lower than conventional and integrated systems equal to 95,848 MJ and 94,060 MJ, respectively. This is mainly due to the ban of chemicals. Economic analysis showed that organic farms were more profitable compared with the other farming methods, because of the greater selling price and the EU economic support, reaching an average net profit of 4255 € ha−1 against 3134 € ha−1 of integrated farms and 2788 € ha−1 of conventional ones. The economic efficiency of energy from clementine production was 0.058 € MJ−1 in the organic farming, higher compared to the other two farming systems equal to 0.033 € MJ−1 on average.
