>> The relation between consumption and water use
"The interest in the water footprint is rooted in the recognition that
human impacts on freshwater systems can ultimately be linked to human
consumption, and that issues like water shortages and pollution can be
better understood and addressed by considering production and supply
chains as a whole," says Professor Arjen Y. Hoekstra, creator of the water footprint concept and scientific director of the Water Footprint Network.

"Water problems are often closely tied to the structure of the global
economy. Many countries have significantly externalised their water
footprint, importing water-intensive goods from elsewhere. This puts
pressure on the water resources in the exporting regions, where too
often mechanisms for wise water governance and conservation are
lacking. Not only governments, but also consumers, businesses and civil
society communities can play a role in achieving a better management of
water resources."
>> 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.
