Jenny Kehl (in his blog: how virtual water is lost) said that one often does not hear of water "moving" across oceans, locked in sacks and cartons of food. Yet food exports hide the significant global trade in water, which could be made transparent and reorganised to reduce water stress and increase global food security. Several of the world's most water-scarce regions are producing the most water-intensive crops - for example, water-intensive rice grown in arid parts of Australia, Mexico and the American West for export to Asia or Europe. http://wildsingaporenews.blogspot.in/2013/03/how-virtual-water-is-lost.html
