The national water saving of a country as a result of trade in a certain commodity is calculated as the net import volume of this commodity times the water footprint of the commodity per commodity unit in the country considered. A negative sign means a net national water loss instead of a saving. Here, blue water savings through the trade of industrial and agricultural products are considered. Annual estimations are given for the period 1996-2005, in million cubic meter per year. In the table, data are also disaggregated per commodities: crop products, animal products, and industrial products.Methodology and results can be found here: http://temp.waterfootprint.org/Reports/Report50-NationalWaterFootprints-Vol1.pdf For more information, visit the Water Footprint Network: http://temp.waterfootprint.org/?page=files/WaterStat
