“The Southeast may be in a sweet spot,” said Dr. Richard McNider from The University of Alabama in Huntsville. “We are one of the few places in the country with both the water and the land that will be needed to substantially increase farm production.
“That could become very important in the near future, as California and other western states continue to struggle with escalating water shortages. Southern New Mexico, for instance, recently set an all-time record for consecutive days without rain.”
Supported by a $2.2 million grant from the U.S. Department of Agriculture, McNider leads a team that will spend the next four years studying the environmental and economic impacts that widespread expansion of irrigated agriculture might have in the Southeast. The test region includes Alabama, Mississippi, North Florida, Georgia and South Carolina.
“If the forecasts for climate change are accurate, the dry western states will get drier and the wet states will get wetter,” said McNider, a professor emeritus of atmospheric science at UAHuntsville. “Whether we have climate change or not, the western region is very likely to return to the ‘normal’ climate of the previous 500 years, which is much drier than the climate of the past 100 years.“In either case, the impact on our food, fiber and now energy security will be significant. Now is the time to start thinking about how we deal with these issues, instead of waiting for the crisis that we can see coming at us.”
The research team includes climate and weather modeling experts at UAHuntsville, ecologists at The University of Alabama (Tuscaloosa), agricultural economists at the University of Georgia, crop modelers at Washington State University, water policy experts at California State University at Long Beach, and hydrology modelers at the U.S. Forest Service.
The study’s goals include determining how much surface water is available for irrigation, and how much is needed for optimum farm production. The team will look at the environmental impact of taking water out of local ecological systems and whether large-scale irrigation can be sustained over long periods of time.
Several factors in addition to climate change may be coming together that will make irrigation-assisted farming in the southeast more economically attractive, McNider said. Rising fuel costs are raising the price of shipping across the country fruits and vegetables that once were raised east of the Mississippi River. The growing demand for alternative fuels, especially ethanol and biodiesel, means droughts or flooding in the Midwest might cause drastic swings in prices for both food and gasoline in the future.
“We have made ourselves vulnerable to drought in the Midwest, at the same time we deal with almost inevitable water shortages in the West,” McNider said.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
