Renowned expert Charles J. Vörösmarty addresses global water crisis

The world’s streams, rivers and lakes are under increasing stress because of human water management – and mismanagement – that threaten aquatic biodiversity and the water supply, Charles J. Vörösmarty said recently during the second annual John R. Mather Visiting Scholars Lecture.

Vörösmarty, professor of civil engineering with the City College of New York, presented “Global Water Crisis: The Slippery Slope” on May 3 at the University of Delaware’s Roselle Center for the Arts.

“The contemporary water system is really defined increasingly by the actions of humans,” he said. (more…)

Testing the Water for Bioenergy Crops

*Water significant limiting factor in growing crops like switchgrass*

Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.

They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.

“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)
