Some facts and figures
The production of one kilogram of beef requires 15 thousand litres of water (93% green, 4% blue, 3% grey water footprint). There is a huge variation around this global average. The precise footprint of a piece of beef depends on factors such as the type of production system and the composition and origin of the feed of the cow.

The water footprint of a 150-gram soy burger produced in the Netherlands is about 160 litres. A beef burger from the same country costs about 1000 litres.

The water footprint of Chinese consumption is about 1070 cubic meter per year per capita. About 10% of the Chinese water footprint falls outside China.
Japan with a footprint of 1380 cubic meter per year per capita, has about 77% of its total water footprint outside the borders of the country

The water footprint of US citizens is 2840 cubic meter per year per capita. About 20% of this water footprint is external. The largest external water footprint of US consumption lies in the Yangtze river basin, China.
The global water footprint in the period 1996-2005 was 9087 Gm3/yr (74% green, 11% blue, 15% grey). Agricultural production contributes 92% to this total footprint.
Water scarcity affects over 2.7 billion people for at least one month each year.

Water footprint reduction at home
• installing water saving toilets• applying a water-saving showerhead, • closing the tap during teeth brushing • using less water in the garden • not disposing medicines, paints or other
pollutants through the sink. • using rain water

How comunities could save water
The goverment has to put in new pipes to make sure there are no leaks and no water will be lost.
