dc.description.abstract [ES] California es el estado con mayores ingresos por exportación de productos agrícolas en Estados Unidos. En la definición de agua exportada se contabiliza el agua contenida físicamente en los productos agrícolas cultivados y transportados fuera de una frontera geográfica, adicionalmente se incluye la evapotranspiración inducida por el riego del cultivo. Como consecuencia de las condiciones climáticas, el agua evapotranspirada se pierde y no está disponible en el ciclo hidrológico local. En el presente estudio, para la estimación del agua exportada se utilizaron datos de los 50 productos agrícolas más exportados desde California (período 2000-2012). Los resultados muestran que, en promedio, el agua exportada en productos agrícolas corresponde a 2.88×1010 m3 año-1, lo que equivale al 68.3% del agua utilizada en riego del cultivo. La mayor parte del agua exportada (67.7%) está representada en la evapotranspiración inducida por el riego del cultivo. El agua contenida físicamente en los productos agrícolas exportados se calculó en 2.32×108 m3 año-1, esto representa menos del 1% del total anual de agua utilizada en California para riego. es_ES
dc.description.abstract [EN] California is the state with the highest income from export of agricultural products in the United States. The total exported water is defined as the physical water contained in crops transported outside a geographic border plus the water lost as induced evapotranspiration as a result of crop irrigation. As a consequence of environmental conditions, the evapotranspiration water is no longer available inside the local hydrologic cycle. In this research, a data set for California’s 50 most exported agricultural commodities (in the period 2000-2012), has been used to quantify exported water. The results show that, on average, the overall exported water in California’s agricultural products was 2.88×1010 m3 yr –1, equivalent to 68.3% of the total water used in agricultural irrigation. The majority of the exported water is in the form of induced evapotranspiration, totaling 67.7% of the annual total water used in irrigation. The physical water content contained in crops was approximately 2.32×108 m3 yr –1, representing less than 1% of the total water used in irrigation and of the induced evapotranspiration. es_ES
