Water Footprint in a Basket of Exportable Agricultural Products of San Juan Province

This paper calculates the water footprint (WF) and virtual water (VW) for a basket of exportable agricultural products of San Juan province. This basket includes: onion, white garlic and grapes for raisins. The VW of these three productions is calculated and the consumption is evaluated in relation to the theoretical water reservoir capacity of the province. It is compared with results of other jobs. The methodology used is based on the WF assessment manual and on Food and Agriculture Organization’s (FAO’s) CROPWAT 8.0 model to identify the crops’ water requirements and on the CIMWAT 2.0 climate database. Finally, recommendations are made for a more efficient use of water for agricultural production.
