In recent years, the agrifood sector has been relevantly impacted by resource shortage, food loss and waste across the whole supply chain. This study assesses, from a life cycle perspective, the water footprint of the fruit and vegetable losses occurring within the Italian agrifood supply chain, analyzing the potential linkages between circular economy policies and water management. The study methodology consists of three consequential steps: the definition of system boundaries, the data collection from databases and reports, and the processing of said data. Based on data availability of food losses, the following food items were chosen for the analysis, representing about 60% of the Italian fruits and vegetables domestic supply: tomatoes and onions for the macro-group of vegetables; orange, lemons, apples and grapes for the macro-group of fruits. Assessing the water footprint for the six categories of products, this study found out that, although less than other products, the amount of grapes lost along the supply chain determines a very high percentage of water loss. The tomato supply chain has proved to be the most sustainable in terms of water loss, due to the low amount of water needed to cultivate tomatoes. The analysis of the Italian trade market of fruits and vegetables has shown that water losses are mainly due to imports from France and Spain, in line with the high trade volumes. Finally, a weakness of the Italian fruit and vegetable supply chain was observed in the transport phase, because in this phase large quantities of food loss are associated with large volumes of water loss. Far from being the only tool to be used in the decision-making processes, the assessment of water loss embodied in the food loss, can be useful for managing the supply chain processes of perishable foods, ensuring process yield improvements, food quality traceability and environmental impact mitigation.
