“Japan has a lot of rain and enough water, but Japan imports a huge amount of water.”(Minoru Okazaki, a specialist of water problems)

Virtual Water
Virtual water is the total amount of water consumed during its process of production.
For example, the total volume of water used in a food product would include the water used in
the agricultural process and the water used in packaging and shipping. Virtual water isessentially all of the “hidden” water behind a product. Every product we consume contains
virtual water.
Virtual water is indirect water use, as opposed to direct water use, which includes
drinking water, bathing, and cooking. It is said that the average consumers use 15 water-filled
bathtubs. Every product has a unique water footprint. Meat is the most incredible virtual waterconsuming product. For example:
A hamburger uses approximately 2,400 liters of virtual water. Water is consumed during
the entire process, from growing feed crops for the cows to slaughtering and processing
the meat.

A cup of coffee uses approximately 140 liters of virtual water to produce. Water isconsumed throughout the production process, from growing to producing to packaging
and shipping.
When we export a product, we export our water supply — nations export and importbillions of liters of water each year. Trades of agriculture-based products make up
approximately 80 percent of international virtual water. When Argentina exports beef, it isexporting water. When Canada exports grain, it is exporting water. The list goes on.
Food is the primary source of virtual water consumption. The average American
consumes about 33,000 glasses of virtual water every day. These numbers are only expected toincrease with increasing populations. Understanding virtual water is a crucial consideration forsustainable water management.
The majority of the public is unaware of how much water they consume in their daily
lives. It is easy to over-consume, especially when we don’t know how much we are consuming.
Without understanding our consumption, it is unlikely that we will succeed in reducing ourvirtual water footprint. Communities and countries around the world face water issues ofscarcity, sustainability, sanitation, and accessibility.
