This research provides a method for determining the water footprint of the main agricultural products sold from the Junín region to market of the Lima city. To this end, a conceptual model that starts with meteorological data in the area was developed, based on these data the reference evapotranspiration (ETo) was estimated, after being selected crops to which the crop coefficient values were assigned (Kc) according to studies in this area. This has allowed to determine crop evapotranspiration (ETc), which together with the soil surface (per unit of hectare) were used to estimate crop water requirements (RAC). With this result and the crop production (RC) has determined the virtual water content (V) of each agricultural product which is expressed in liters of virtual water per kilogram of product. With this value and the amount of product sold (Ej) the virtual water that is transferred (AVt) to the market Lima was estimated. Virtual water values for agricultural products such as potatoes, wheat, corn, grain corn, green bean, beans, green peas, artichokes, carrots, onion, garlic, barley, quinoa, and root vegetables, ranging from 0,008 to 75,52 Hm3, with a total water footprint of 161,28 Hm3/ year for the 14 crops studied. Virtual water values of each product vary, from one year to another, in their amounts marketed; and it depends on production in the Junín region, which in turn is conditioned essentially to several factors such as climate, consumer demand and the technology used in production systems. Additionally, the results show that the volumes of virtual water between products vary by the quantities marketed. For example, the consumption of a kilogram of potatoes in Lima involves the transfer of 290,92 liters of “virtual water“ from the region of Junín, where the product is produced.
