Global food production has increasingly affected both the environment and human health in substantial and remarkable ways. Among the many concerns global community has to face, Earth’s freshwater resources have been identified as dangerously subject to increasing pressure in the form of consumptive water use and pollution. A deep understanding of the water-food nexus is crucial to support the exploration of more suitable avenues for a sustainable development. In this work, the concept of water footprint (WF) presented by different methodologies – volumetric and impacts oriented approach – has been applied to link impacts on water consumption to the food production and consumption. With regard to the study of the production side, comparison of environmental performances of two vineyard where conventional and organic viticulture were applied, has been performed.

La produzione globale di cibo provoca impatti sia sull’ ambiente che sulla salute umana. Tra le molteplici sfide che la comunità globale deve affrontare, le risorse di acqua dolce della Terra sono state identificate come pericolosamente soggette a una crescente pressione sia in termini quantitativi che qualitativi. Una profonda comprensione del nesso acqua-cibo è pertanto cruciale per lo sviluppo sostenibile. Nella presente tesi è stato applicato il concetto di Water Footprint (WF) calcolata attraverso differenti metodologie – ovvero attraverso approcci di tipo volumetrico e per la quantificazione dei potenziali impatti – al fine di stimare gli impatti sul consumo di acqua conseguenti produzione e consumo di cibo. Per valutare diverse tecniche di produzione, sono state confrontate le prestazioni ambientali di due vigneti coltivati con metodi di agricoltura convenzionale e biologica. Inoltre, sono stati studiati gli impatti sulle risorse idriche in relazione a diversi scenari di consumo alimentare in Italia e Danimarca, per indagare come le scelte alimentari dei consumatori rappresentino una strategia di riduzione degli impatti sull’ acqua. Nel calcolo degli impatti ambientali, i risultati hanno evidenziato il ruolo chiave dell'origine dei prodotti alimentari consumati, insieme alla tipologia dei prodotti e la riduzione di sprechi alimentari.

Abstract
Global food production has increasingly affected both the environment and human health in substantial and remarkable ways. Among the many concerns global community has to face, Earth’s freshwater resources have been identified as dangerously subject to increasing pressure in the form of consumptive water use and pollution. A deep understanding of the water-food nexus is crucial to support the exploration of more suitable avenues for a sustainable development. In this work, the concept of water footprint (WF) presented by different methodologies – volumetric and impacts oriented approach – has been applied to link impacts on water consumption to the food production and consumption. With regard to the study of the production side, comparison of environmental performances of two vineyard where conventional and organic viticulture were applied, has been performed. Additionally, impacts on water resources related to different Italian and Danish dietary patterns have been investigated to understand the positive impacts that demand-side solutions can have. The studies highlighted that the origin of consumed foodstuffs played a key role in the calculation of local environmental impacts. Finally, the analysis showed that consumer’s choices could tackle environmental impact on water use by changing their consumption patterns, selecting less water-demanding products and reducing food waste.File | Dimensione | Formato | |
