There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...
How does transboundary water cooperation begin at the initial stages? Countries in many transboundary basins either do not cooperate at all or have ceased cooperation altogether. Yet cooperation does often prevail, resulting in 688 water-related treaties signed between 1820 and 2007. The question we address here is, by which practices...
This study examined patterns and controls on 35-years of forest succession following logging in the 236 ha South Umpqua Experimental Forest within the Umpqua National Forest in southwestern Oregon. Prior to logging, the overstory in all three watersheds (~50% cover) was composed of Douglas-fir (30-40% cover), grand fir (2 to...
This research provides details of water resource conflict and cooperation in Oregon between 1990 and 2004 by using an event database methodology. Events were concentrated in four of 18 basins. No basin accounted for more that 25% of the total water rights events, the most evenly distributed issue type. Overall...
The conflict over water resources exploitation and sharing in the Aral Sea Basin is one of the most pressing environmental issues yet to be resolved in Central Asia. The fall of the Soviet Union in 1991 and establishment of the New Independent States (NIS) within the Aral Sea Bain led...

The conflict over water resources exploitation and sharing in the Aral Sea
Academics and practitioners agree that in water governance, the quality of a decision making process should influence the quality of the outcome and the degree to which it is accepted by interested parties. However, finding a feasible way to evaluate and then improve the quality of a decision making process...
American Indians presently face health risks posed by exposure to environmental pollutants through different exposure routes including: inhalation (e.g., air particles), ingestion (e.g., fish, water), and dermal contact (e.g., contact with water, soil). Geographic Information Systems (GIS) are increasingly being used in the Environmental Health arena as a tool for...
The U.S. Forest Service on the Willamette National Forest currently employs the “Disturbed Water Erosion Prediction Project” (WEPP) model to determine potential suspended sediment delivery from timber harvests or other treatment scenarios given user-defined hillslope parameters. At the time of this study there was no known calibration or testing of...
In transboundary river basins, political borders oftentimes trace shared rivers across a basin. A border between territories can be seen as a space that is separated; however, it is actually one with the potential to unite populations and environments. A river basin is generally defined by its topography and hydrology....
Over 90 percent of the soy, cotton, and corn sold in the United States are genetically modified crops (GM crops). However, there was a 209 percent growth in USDA certified organic food from 2005-2015, reflecting a growing interest in non-GMO food. The policy debate over GM crops takes place between...
