The Global Water Footprint of Humanity is a project based on research carried out by Unesco and University of Twente in The Netherlands. The project aims to visualize the Water Footprint of 132 countries and to make tangible the impact of human consumption on our freshwater environment. Facing water issues means to understand the use we make of this precious resource. The project aims to illustrate that 86% of our water footprint per capita is due to food consumption (Agricultural Products). In addition we have to bear in mind that when we consume and trade products, we consume and trade all the water that has been used to produce those products (virtual water). There are invisible virtual water flows that happen every second on a global level. When we move products from a country to another, we are moving not only the real products, but virtually all the water that has been used to produce them. It can be much more preferable, for water-scarce countries, to import virtual water via food products rather than using the limited domestic water resources for their production. Virtual water could be the solution to the lack of symmetry of where water is needed and where water is. Taking into account virtual water flows can help Humanity to manage water better, to manage water interdependencies better, to face water needs more efficiently. (Data: Per Capita values expressed in thousands litres per annum).

TOTAL WATER FOOTPRINT The Water Footprint of a nation is the sum of the Internal and External Water Footprint, namely the volume of National and Foreign water resources used to produce, inside and outside the country, all the goods and services consumed by the inhabitants of the country.
