Green Glaciers: The Melting Grasslands of the Tibetan Plateau
Adaptation choices for the plateau are both difficult and limited in the face of such extremely rapid environmental change. Clearly, local livelihoods need to be diversified to reduce human-wildlife conflicts as well as grazing pressure on grasslands. Erosion control mechanisms will be viable in some regions, while other areas should be left fallow to recover slowly. And management strategies for agriculture and endangered species need to shift to reflect the changing characteristics of the landscape.

Fecon BioMass Harvester Seeks To Turn Fire Hazards into Gold
Lebanon, OH—It has been said that one man’s trash is another man’s treasure. That could well be the driving force behind a new product development effort at Fecon. Here design engineers are working to adapt their proven mulching technology to harvest (rather than merely mulch) the woody biomass that is cluttering much of the forested lands in North America. Early indications are that this new technology will be a winner – not only from a sustainable energy production standpoint, but also from the viewpoint of wildland fire control, environmentalists, and from the viewpoint of the forest service contractors who serve these diverse groups.

Absorbing organic pollutants in soils
A new study closely examines the role degrading plant materials play in absorbing organic pollutants in the soil. These “biopolymers” are the waxy, water resistant barriers between the plant cells and the environment. This information is important to evaluate the role of these biopolymers as a natural sorbent for organic pollutants in the environment.

Protecting soil in fire-ravaged landscapes
Following a wildfire, there is often the potential for devastating storm-induced erosion and mudslides. To prevent this possibility, teams of scientists work on these scared landscapes to quickly assess the erosion potential and potential mitigation strategies. By using digital soil and fire severity data, coupled with a Geographic Information Systems (GIS), the process is made much simpler.

Forest fires help power the nitrogen cycle
When fire burns down a forest, nitrate levels go up, and the effects are persistent, according to recent research from University of Montana scientists. They found that charcoal deposited during fire events has the potential to stimulate the conversion of ammonia to nitrates, an important step in the nitrogen cycle.

Thinking the Unthinkable: Fires in Russia Fan Nuclear Fears
(Aug. 11) -- The United States has spent hundreds of millions of dollars and years of effort to help Russia secure its nuclear stockpiles from what is euphemistically referred to as "diversion." But the 600 wildfires raging across the Russian countryside spotlight another risk to the nuclear-industrial complex: natural disaster.

What Causes Mudslides?
Heavy rains in China set off mudslides that washed away part of the town of Zhouqu, in the province of Gansu, and left more than 330 people dead and many more missing.
But heavy rains aren't the only thing that can trigger a mudslide, according to experts.
A sub-category of landslides, mudslides are rivers of rock, earth and other debris that are saturated with water, according to the U.S. Geological Survey (USGS). Mudslides can be slow- or fast- moving, though they tend to grow in size and momentum as they pick up trees, boulders, cars and other materials.

Arsenic in field runoff linked to poultry litter
Fields amended with poultry litter can accumulate significant levels of arsenic, according to studies by USDA-Agricultural Research Service (ARS) scientists and associates. These findings provide key information about the agricultural pollutants that can build up in agricultural soils over time—and possibly migrate into nearby streams and rivers.

Study to gauge Badlands' life span
Wind and water are conspiring to level the iconic South Dakota feature that is the Badlands.
Not to worry, though. The forces of nature move about as fast as glaciers crawl.
Still, two researchers - Badlands National Park paleontologist Rachel Benton and Larry Stetler, a professor at the South Dakota School of Mines - will begin a three-year study this fall to answer the question, "Just how fast are the Badlands eroding?"
