Water footprint promotes sustainable and fair use of water resources

17.10.2008
Together with six global partners including the World Wide Fund for Nature (WWF) and UNESCO, the University of Twente in The Netherlands will found the Water Footprint Network on October 16, 2008.

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 This includes the water needed to produce goods: the water withdrawn from surface as well as ground water and soil water.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.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
