The ‘water footprint’, developed by UT Professor Arjen Hoekstra, gives a detailed insight into the water consumption of individuals, companies and countries. The new network will promote sustainable, fair and efficient use of water on a global scale.
The ‘water footprint’ measures the amount of water that a country, company or individual uses each year. This includes the water needed to produce goods: the water withdrawn from surface as well as ground water and soil water. For a simple cup of coffee, for example, an average of 140 litres of water is needed, 2,700 litres for a cotton shirt, 16,000 for a kilo of beef. Taking all this into account on a global scale, we get a water footprint of 7,500 billion cubic metres a year. Per individual this is an average of 1,250 cubic meters a year. An American citizen uses twice that amount, a Chinese or Indian citizen far less. In The Netherlands, just 20 percent of the water footprint is Dutch water, the rest of it is foreign.
Thus, the water footprint also indicates the geographic spread: where on the planet do we use most of the water for our goods? The concept has been developed by Professor Arjen Hoekstra, who heads the Twente Water Centre at his university and is the scientific director of the new Water Footprint Network: “Many countries do not produce the typical water-intensive products themselves. This puts a huge pressure on the water resources of exporting countries, where too often wise water governance is lacking. The water footprint doesn’t just help governments in better management of water resources; companies and public organisations can take their responsibility as well.”
The Water Footprint Network helps increasing awareness by developing new standards and tools. “A unique opportunity for governments and businesses to apply the water footprint methodology and reduce the water risks to economy, society and nature,” says executive director Derk Kuiper. The Water Footprint Network will soon be open to all relevant stakeholders including academic institutions, government and non-government organisations, companies and UN organisations.
The Water Footprint Network is a joint initiative of the University of Twente, the World Wide Fund for Nature, UNESCO-IHE Institute for Water Education, the Water Neutral Foundation, the World Business Council on Sustainable Development, the International Finance Corporation (part of the World Bank group) and the Netherlands Water Partnership. The public launch of the network will be in December 2008.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
