Virtual Water

The basic building block of Water Footprint is the concept of virtual water, which is the total amount of water used up to produce agricultural produce and other commodities.  This water is said to be virtual – because it is used up in the various stages of the production process and is no longer contained in the final product. By revealing this “hidden” water, the Water Footprint concept enhances our understanding of the many connections between our consumption habits and freshwater resources.

Water Footprint

Water Footprint is a multidimensional indicator. In addition to presenting the virtual water content of a product, it also tells us the composition of a product’s Water Footprint in regard to the types of water consumed in the production process, as well as the spatial and temporal dimensions of that consumption. Water Footprint captures the total amount of water used up in the various stages of a production process of a commodity.

Do we need to carry "water" ?

 

This time we don’t need to carry actual water, because we are already carrying a lot of precious water resources on us. We introduce the concept of Water Footprint to help our participants visualize and understand the many connections between our buying habits and our world’s shrinking freshwater bodies.

*The number represents the Water Footprint of the item produced. Since each item is made of different materials and methods, this data is for reference only.
