At global scale, the majority of world water withdrawal is for the agricultural sector, with differences among countries depending on the relevance of agri-food sector in the economy. Virtual water and water footprint could be useful to express the impact on the water resources of each production process and good with the objective to lead to a sustainable use of water at a global level. International trade could be connected to the virtual water flows, in fact through commodities importation, water poor countries can save their own water resources. The present paper focuses on the bilateral virtual water flows connected to the top ten agri-food products traded between Italy and China. Comparing the virtual water flow related to the top 10 agri-food products, the virtual water flow from Italy to China is bigger than the water flow in the opposite direction. Moreover, the composition of virtual water flows is different; Italy imports significant amounts of grey water from China, depending on the different environmental strategies adopted by the two selected countries. This difference could be also related to the fact that traded commodities are very different; the 91% of virtual water imported by Italy is connected to crops products, while the 95% of virtual water imported by China is related to the animal products. Considering national water saving and global water saving, appears that Italy imports virtual water from China while China exerts pressure on its water resources to supply the exports to Italy. This result at global scale implies a global water loss of 129.29millionm3 because, in general, the agri-food products are traded from the area with lower water productivity to the area with the higher water productivity.

In the agribusiness wine is certainly a very interesting sector to analyze. The specific aim of this work is to assess water efficiency and economic water productivity for the Italian wines with Appellation of Origin (AO). This assessment could represent a potential management instrument to improve production performances from a more integrated perspective, pursuing new market trends. The study is related to Italy, the first worldwide producer, and analyzes the available data of AO wines, which globally have specific features, being strictly connected with the territory and its background. The results show the top and bottom five AO wines in terms of crop water use and economic water productivity and their trends during the period 2011-2015, based on average annual change rates. Results of this study are relevant for the wine sector since they can guide decision makers on vine variety selection in the context of micro- and macro-level sustainability of water resource use.

In this paper, we present a new approach based on the Grey Water Footprint (GWF) concept for the determination of groundwater nitrate contamination, with a focus on the agricultural impact in the Southern Apulia Region (Italy). The GWF assessment allows us to highlight wells where nitrate contamination is higher and for which a verification of the nature of contamination is necessary, potentially identifying certain contexts associated with risk factors present in the area. Data show higher nitrate GWF values for vineyards than for olive groves, particularly in areas used for the production of table grapes. Indeed, it is possible to observe that the Western Ionian-Tarantino arch is characterized by a high average level of the GWF indicator, area characterized by an agricultural land use (vineyards, orchards, simple arable land). Another important area is the Brindisi plain, predominantly characterized by an agricultural vocation and a related fertilizer use. The situation in the whole Salento peninsula is more heterogeneous. The results of the GWF show high values in equally distributed points with a clear frequency in the coastal areas of the Ionic arch (Eastern Tarantino and Salento). The Water Footprint methodology and in particular the GWF approach used in this study conceives a useful indicator for the agricultural policy planning processes, a criterion to establish land use management according to the status of hydrological basin and a tool for assessing the pollution monitoring programs.
