Geography of virtual water trade WATER MANAGEMENT JOURNAL

Virtual water is the amount of water consumed in the process of producing a commodity that is traded abroad. Virtual water Trading Geography is determined based on the calculation of the amount of water consumed by the goods being imported or exported. Although virtual water trade can be calculated for all agricultural and nonagricultural commodities, But the virtual water water of agricultural products is paying more attention. Many countries preserve their precious water by importing some products that consumed more water and produce products that can be produced with less water inside the country. Although in level global, virtual water trade in agricultural products has led to an increase in water efficiency on the earth and has resulted in savings. But some countries, with their additional exploitation of their water resources, produce products to the global marketplace. Studies and research on the "virtual water" and "water footprint" and its trade have so far been carried out more internationally and across countries, but this can also be very important in the federal regions.
