NASA’s Soil Moisture Active Passive (SMAP) satellite to help Farmers manage Drought conditions

 

Written by Alan Buis

NASA - National Aeronautics and Space AdministrationPasadena, CA – About 60 percent of California is experiencing “exceptional drought,” the U.S. Drought Monitor’s most dire classification. The agency issued the same warning to Texas and the southeastern United States in 2012. California’s last two winters have been among the driest since records began in 1879. Without enough water in the soil, seeds can’t sprout roots, leaves can’t perform photosynthesis, and agriculture can’t be sustained.

Currently, there is no ground- or satellite-based global network monitoring soil moisture at a local level. Farmers, scientists and resource managers can place sensors in the ground, but these only provide spot measurements and are rare across some critical agricultural areas in Africa, Asia and Latin America.

For several months, California has been in a state of "exceptional drought." The state's usually verdant Central Valley produces one-sixth of the U.S.'s crops. (White House via Wikimedia Commons)

Tennessee Department of Agriculture reports seven additional Counties quarantined for Emerald ash borer

 

The Tennessee Department of AgricultureNashville, TN – A quarantine for Emerald Ash Borer (EAB), an invasive insect that destroys ash trees, has been expanded to seven additional counties in Middle and East Tennessee. Clay, Fentress, Macon, Morgan, Overton, Pickett, and Rhea counties have been added to the list of areas restricted for the movement of ash trees and ash tree products.

This brings the total number of Tennessee counties under a state and federal EAB quarantine to 34.

Austin Peay State University Botanical Garden showcases area’s rare and endangered plants

 

Austin Peay State University - APSUClarksville, TN – A few years ago, three tall, flowering cherry trees grew on the western side of Austin Peay State University’s Sundquist Science Complex. They provided a nice, welcoming entry into the building, but in 2007, Tennessee suffered from a record-setting drought.

Temperatures reached 113 degrees Fahrenheit that summer, and by the fall, the 20-foot tall trees were dead.

American Heart Association says eating more fruits, vegetables may cut stroke risk worldwide

 

American Heart AssociationDallas, TX – Eating more fruits and vegetables may reduce the risk of stroke worldwide, according to new research in the American Heart Association’s journal Stroke.

Researchers conducted a meta-analysis of 20 studies published over the last 19 years to assess the effects of fruit and vegetable consumption on risk of stroke globally. The combined studies involved 760,629 men and women who had 16,981 strokes.

NASA scientists study changes to Earth’s Ozone levels

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth’s atmosphere probably won’t be affected much by projected future strengthening of the circulating winds that transport ozone between Earth’s two lowest atmospheric layers.

The finding is good news, since human and plant health are harmed by exposure to ozone near the ground. Significant increases in ozone in Earth’s lowest atmospheric layer, the troposphere, would also lead to additional climate warming because ozone is a greenhouse gas.

Astronauts aboard the International Space Station captured this photograph of Earth's atmospheric layers on July 31, 2011, revealing the troposphere (orange-red) to the stratosphere and above. Earth-observing instruments in space allow scientists to better understand the chemistry and dynamics occurring within and between these layers. (NASA/JSC Gateway to Astronaut Photography of Earth)

NASA’s Aqua and Terra Spacecraft take images of California Rim Fire endangering Yosemite National Park

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Rim Fire burning in and near Yosemite National Park in California continues to grow and move its way up in the record books. As of August 27th, CAL FIRE (California Department of Forestry and Fire Protection) reports that the fire, which started August 17th, had consumed nearly 180,000 acres, making it the seventh largest wildfire in California’s recorded history.

The fire is one of 10 active major wildfires burning across California as of August 27th.

Visible image of California's Rim Fire acquired Aug. 23rd, 2013 by the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra spacecraft, showing extensive, brownish smoke. The imaged area measures 236 by 215 miles (380 by 346 kilometers). (Image credit: NASA/GSFC/LaRC/JPL, MISR Team)

Tennessee Department of Agriculture says Emerald Ash Borer findings continue to spread

 

The Tennessee Department of AgricultureNashville, TN – Emerald Ash Borer, an invasive insect that destroys ash trees, has been found in Jackson and Scott counties. The identification was made recently and has been confirmed by USDA.

Both counties will now be placed under quarantine. Earlier this summer, Hamilton County was also placed under quarantine when EAB was found in trees near a rail hub in Chattanooga, TN.
