Matching water supply and water demand A new assessment of available water resources, published today by the Joint Research Centre (JRC), reveals that large areas in Spain and Eastern Europe have on average less than 200 mm freshwater available every year while the demand for water is three to ten times higher. The report 'Current Water Resources in Europe and Africa' shows variations in yearly freshwater generation from 10 mm to over 500 mm for Europe and from less than 0.1 mm to over 500...

A new species adds to evidence that subarctic regions with vanishing waters contain unique aquatic animals Freshwater ecosystems in northern regions are home to significantly more species of water fleas than traditionally thought, adding to evidence that regions with vanishing waters contain unique animal life. The new information on water fleas -- which are actually tiny crustaceans -- comes from a multi-year, international study that was published Feb. 24 in the journal Zootaxa....

In the heart of the Mojave Desert vast torrents of water flow freely in massive fountains, pirate lagoons, wave machines and casino waterfalls: the prodigality that characterizes Las Vegas is sucking America dry, says one of the world´s leading water authorities. The issue of overexploitation of precious groundwater resources in an arid land faces Australia too, cautions Robert Glennon, Professor of Law at the University of Arizona and author of the book Unquenchable: America´s...

Humans Found Gradual Transition To Agriculture

According to a new study of ancient pottery, humans may have undergone a gradual transition from fishing, hunting and gathering to farming. Researchers from the University of York and the University of Bradford analyzed cooking residues preserved in 133 ceramic vessels from the Western Baltic regions of Northern Europe to establish whether these residues were from terrestrial, marine or freshwater organisms. The team studied ceramic pots from 15 sites that dated back to about 4,000...

"Of the 675 fish species found in southeastern waters, more than 25 percent are considered imperiled," Donald J. Orth, the Thomas H. Jones Professor of Fisheries and Wildlife Sciences in Virginia Tech's College of Natural Resources and Environment, told the audience of scientists during his keynote address at the Southeastern Fishes Council annual meeting in mid November 2010 in Athens, Ga. The theme of the meeting was "Got Water? At the Crossroads of Fish Conservation and Water Supply."...

Helping understand ecosystem changes and improving restoration with soil data Rising sea levels and coastal development are threatening coastal freshwater wetlands with saltwater intrusion. While most ecosystem restoration projects have focused on surface water and groundwater, new research finds that conditions in the vadose zone, the unsaturated soil below the surface but above the water table, are of particular importance to seedling survival in coastal floodplain ecosystems. ...

Michigan State University scientists have developed a pioneering, comprehensive approach that makes conserving and managing freshwater lakes, streams and wetlands more integrated and effective. "We call our approach landscape limnology," said Patricia Soranno, MSU associate professor of fisheries and wildlife. "It's a new way to study freshwater that considers all freshwaters together "“ lakes, rivers and wetlands "“ as they interact with one another and with natural and human...

Researchers in India have demonstrated that microscopic aquatic creatures could be used as the ecological equivalent of a canary in a coalmine for assessing inland freshwater lakes and ponds. Writing in the World Review of Science, Technology and Sustainable Development the team explains how diatoms respond badly to pollutants and sewage contamination. Bijaya Kumar Padhi, Jnanendra Rath, and Pratap Kumar Padhy of the Visva-Bharati University, in Santiniketan, India, have looked at the...

Biodiversity in freshwater systems is impacted as much or more by environmental change than tropical rain forests, according to University of Oklahoma Professor Caryn Vaughn, who serves as director of the Oklahoma Biological Survey. "When we think about species becoming extinct, we don't necessarily think of the common species in freshwater systems, many of which are declining," says Vaughn. "We need to be concerned about these declines, because these common species provide many goods and...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...

Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface. Some rain evaporates as it falls, especially through dry air. This type of rainfall is known as...
