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
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!
