Resumen:
Mendoza is one of the 9 World Wine Capitals, a dryland in the mid-west of Argentina where the wine industry has shown a fast growth over the last years. In this province, there are three irrigated oasis occupying only 3% of its total area, where agriculture, residential settlements and industry share the available water to satisfy their needs. In drylands, agriculture is conditioned by the availability of blue water, since green water is not enough to fit the water requirements. These types of lands are characterized by the aridity index, which relates the annual precipitation with the potential evapotranspiration. When this ratio is below 0,05 or between 0,05 and 0,20 the land is classified as hyperarid and arid, as it is the case of Mendoza. This work is intended to determine the water footprint inventory of one of the most emblematic products in the considered region. The study also assesses the impact of water use in terms of availability and water scarcity, in order to have a complete picture of the use of water footprint as sustainability indicator. Results show that water footprint could be an accurate indicator in drylands, useful for assessing the opportunities given by sustainable agriculture management practices, for proposing efficient irrigation systems or for considering the expansion of agriculture borders in terms of land use according to water availability.
