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 research 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.展开更多

Especially, it is said, winter-flooding is control paddy weeds and there is the farming potential that the annual rice yield is high. However, there is no detailed research about the effects of weed communities by winter-flooding, as the purpose of this study, we investigated the effects of the inhibition of weed communities (life cycle, harmful weed) by winter-flooding at a shore of Inba Lake, Chiba Prefecture, Japan, and compared them to paddy weeds in a dry paddy field. Methods examined the plant height (cm) and the cover degree class of all appearance species in each quadrant frame (1 m2). Quadrant in the two type paddies were 10 frames (D1-D10) at the control, and were 10 frames (W1-W10) at the treatment (Figure 1). In a winter-flooded paddy field, species number and plant volume of winter-annual plants decreased in the third winter after winter-flooding, In particular, the plant volume of Alopecurus aequalis, Cardamine flexuosa decreased significantly. We considered that the cause of this decrease was due to the depth of flooding (more than 10 cm). Eleocharis kuroguwai and Echinochloa oryzoides, which are perennial plants, Sagittaria trifolia, which is an annual plant, increased in a winter-flooded paddy field in the third summer after winter-flooding. We considered that these species grew thicker at places where the seeds germinated, and grew easily, because the conservation situation of the seeds fitted well under the winter-flooding conditions. They started to grow immediately after the drainage of water. The period of drainage coincided with increasing light intensity and temperature. In addition, the annual rice yield of the third year after winter-flooding was higher than that of the habitual practice rice field.展开更多

In this context, the methodology of LCA （life cycle assessment） is certainly one of the most innovative methods in the field of environmental protection as it allows evaluating the environmental burdens associated with a product, process or activity by identifying and quantifying material and energy consumption and environmental emissions. The objectives focus on finding the main impacts of the wine life cycle, as well as identifying crucial activities/stages in the wine production which establish the largest impacts. This paper＇s objective is to expose the advantages resulting from the use of the LCA method in the wine production sector, with a specific application to wine production in the Tuscany region.展开更多
