NSF partners with international team to gather new information on hidden environments and past climate conditions in Antarctica National Science Foundation- (NSF) funded researchers have successfully tested equipment to map the hidden distribution of groundwater and ice in the McMurdo Dry Valleys region for the first time in Antarctica. The mapping technique, an airborne electrical resistivity instrument, will enable researchers to study microbial ecosystems in sub-glacial environments....

As the UN marked World Food Day earlier this week, international representatives convened in Korea to discuss ways to curb the loss of productive land to desertification. Satellites play an important role in the monitoring and assessment of drylands.   Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. It is caused primarily by human activities and climatic variations because dryland ecosystems are extremely vulnerable to over-exploitation,...

Sediments Frozen in Time Provide Clues Focusing on a controversial hypothesis that ice existed at the equator some 300 million years ago during the late Paleozoic Period, two University of Oklahoma researchers originated a project in search of clues to the Earth's climate system. "The Paleozoic Period was a rare time in history," says Gerilyn Soreghan, OU professor of geology. "Broadly speaking, it was the last time our planet experienced the type of climate system we have today and in the...

The forests of Argentina have suffered a loss of between 60 percent and 70 percent overall, the Environmental Secretariat reported on Friday. "In 100 years, we have lost between 60 and 70 percent of our forest heritage," said Environmental Undersecretary Sergio La Rocca. Forests have fallen from 100 million hectares in 1900 to 33.19 million hectares currently, officials said during the ninth session of a conference for the United Nations Convention to Combat Desertification (UNCCD). A study...

Scientists gather in Buenos Aires to find a way forward for agriculture in vast dry areas, where the poor are most vulnerable to land degradation and climate change As climate change negotiators continue to skirt the role of agricultural land use in reducing greenhouse gas emissions, top scientists working on land management in the world's vast dry areas will gather this week in Buenos Aires, Argentina, determined to make the case that thwarting desertification in drylands is viable and also...

In a new study, researchers have found what they believe to be a new pathway that allowed modern humans to spread beyond their ancestral homeland about 120,000 years ago. Rivers once flowed from the central Saharan watershed all the way to the Mediterranean, the team of researchers from the Universities of Bristol, Southampton, Oxford, Hull and Tripoli in Libya explain in the journal PNAS. These rivers could have made up a "wet corridor" through Libya for ancient human migrations out of...

On an almost daily basis, Jeff Peterson, MD, would be informed that there were "beaucoup de malades nomads" --many sick people--who had come by camel in search of medical assistance. Most of them had never received any medical care before. Peterson, who was the physician in Running the Sahara, a documentary film that chronicles the incredible journey of three runners' ultra-endurance expedition through Africa's Sahara Desert, had anticipated that such a need might arise. What he...

Sahara Energy, engaged in oil and gas exploration and development, has sold its 30% operated working interest in one gas well located at Gold Creek, Alberta, for proceeds of approximately C$180,035. Proceeds from the sale will be used to pay down Sahara's existing bank debt. Subsequent to the application of the proceeds from the sale, Sahara's current bank indebtedness will be approximately C$20,000. Sahara will reportedly continue to focus on developing its lands in its core area of...
