摘要：Integrated water protection implies not only protection of water quality; but also protection of the quantity of useable water as one of the most important natural resources. This includes virtual water; which is water as an integral part of the product; used during its production process and contaminated by it. It connects water with trade. Virtual water can be qualitatively determined by the water footprint concept; which refers to the amount of water used by any defined body; ranging from an individual to the entire nation. Further studies of water consumption and usage in food production led to the development of water footprint as a three-part system; comprising blue; green and grey water. A shift from the previous exclusive importance of blue water to the newly emerged significance of green water zone; led to a conclusion that with adequate water management; even countries suffering from a serious water shortage could produce enough food. The concept of virtual water led to new perspectives in understanding the ways water is traded worldwide; in terms of volumes virtually contained within the traded products.
