Please calculate the Waterfoodprint with your students for our project "EuroWater".

Your individual water footprint is equal to the water required to produce the goods and services consumed by you.

Please use it to discuss the water consumption.

 

 

Why bothering about your water footprint?

Freshwater is a scarce resource; its annual availability is limited and demand is growing. The water footprint of humanity has exceeded sustainable levels at several places and is unequally distributed among people. There are many spots in the world where serious water depletion or pollution takes place: rivers running dry, dropping lake and groundwater levels and endangered species because of contaminated water. The water footprint refers to the volumes of water consumption and pollution that are ‘behind’ your daily consumption. 
 

Water footprint reduction at home

As a consumer, you can reduce your ‘direct water footprint’ (home water use) by installing water saving toilets, applying a water-saving showerhead, closing the tap during teeth brushing, using less water in the garden and by not disposing medicines, paints or other pollutants through the sink.
 

Save water in the supermarket

Your ‘indirect water footprint’ – the water consumption and pollution behind all the goods you buy – is much larger than your direct water footprint at home. You have basically two options to reduce your indirect water footprint. One option is to substitute a consumer product that has a large water footprint by a different type of product that has a smaller footprint. Examples: eat less meat or become vegetarian, drink tea instead of coffee, or even better drink plain water. And replacing cotton clothes by clothes from artificial fibre saves a lot of water.

But this approach has limitations, because you may find it difficult to drastically change your consumption pattern. What still remains, however: you can select the cotton, beef or coffee that has a relatively low water footprint or that has its footprint in an area that doesn’t have high water scarcity. This requires that retailers provide you with proper information to make such choices. In this respect, ask product transparency from businesses and regulation from governments!
