Abstract(s)
In the Mediterranean region, climate change is likely to generate an increase in water
demand and the deterioration of its quality. The adoption of precision viticulture and the best
available techniques aiming at sustainable production, minimizing the impact on natural resources
and reducing production costs, has therefore been a goal of winegrowers. In this work, the water
footprint (WFP) in the wine sector was evaluated, from the vineyard to the bottle, through the
implementation of a methodology based on field experiments and life cycle assessment (LCA) on
two Portuguese case studies. Regarding direct water footprint, it ranged from 366 to 899 L/FU
(0.75 L bottle), with green water being the most significant component, representing more than 50% of
the overall water footprint. The approach used in the current study revealed that although more than
97.5% of the water footprint is associated with vineyard, the winery stage is responsible for more than
75% of the global warming potential indicator. A linear correlation between the carbon footprint and the indirect blue water footprint was also observed for both case studies. Climate change is expected
to cause an earlier and prolonged water stress period, resulting in an increase of about 40% to 82% of
blue WFP.
