Nonpoint source pollution from agriculture is the main source of nitrogen and phosphorus in the stream systems of the Corn Belt region in the Midwestern US. The eastern part of this region is comprised of the Ohio-Tennessee River Basin (OTRB), which is considered a key contributing area for water pollution and the Northern Gulf of Mexico hypoxic zone. A point of crucial importance in this basin is therefore how intensive corn-based cropping systems for food and fuel production can be sustainable and coexist with a healthy water environment, not only under existing climate but also under climate change conditions in ...


Degraded Water Quality In Lakes: Consequences For Use, Hocheol Jeon, Catherine L. Kling, Yongjie Ji 2017 Iowa State University

Degraded Water Quality In Lakes: Consequences For Use, Hocheol Jeon, Catherine L. Kling, Yongjie Ji

Catherine Kling

Iowa, like many states in the Midwest, suffers from poor water quality. Excess nutrients in the state’s lakes and streams contribute to odor, limited clarity, excess algae and plant growth, and can contribute to a number of other undesirable changes to habitat and water quality. These changes, in turn, can reduce the usage and enjoyment of lakes and streams. Likewise, improvements in water quality brought about by reduced nutrient pollution or lake improvement projects can increase the number of visitors and their enjoyment of natural environments. To better understand what Iowans value about their natural environment and how changes ...

Environmentally Friendly Industries: An Examination Of Ecotourism As The Solution To The Environmental Degradation Caused By The International Tourism Industry, Whitney Michael 2017 Johnson & Wales University

Environmentally Friendly Industries: An Examination Of Ecotourism As The Solution To The Environmental Degradation Caused By The International Tourism Industry, Whitney Michael

Honors Theses – Charlotte Campus

The increasing visibility of ecological alterations due to global climate change have required high-impact industries to reexamine their environmental impact. Transnational organizations such as the United Nations have identified the current management practices of the international tourism industry as a significant contributing factor to global warming. The high volume implications of the large-scale establishments necessary to lodging facilities in the tourism trade are responsible for damages such as resource depletion and pollution. Existing levels of environmental impact show irreparable and imminent damage to the world environment if current methods of the industry are allowed to continue.

New trends in consumer ...

The Irreversible Momentum Of Clean Energy, Barack Obama 2017 President of the United States

The Irreversible Momentum Of Clean Energy, Barack Obama

US Department of Energy Publications

The release of carbon dioxide (CO2) and other greenhouse gases (GHGs) due to human activity is increasing global av-erage surface air temperatures, disrupting weather patterns, and acidifying the ocean (1). Left unchecked, the continued growth of GHG emissions could cause global average tem-peratures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations (1). Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is ...

Can Community Structure Track Sea-Level Rise? Stress And Competitive Controls In Tidal Wetlands, Lisa M. Schile, John Callaway, K M. Suding, N M. Kelly 2017 University of San Francisco

Can Community Structure Track Sea-Level Rise? Stress And Competitive Controls In Tidal Wetlands, Lisa M. Schile, John Callaway, K M. Suding, N M. Kelly

Environmental Science

Climate change impacts, such as accelerated sea-level rise, will affect stress gradients, yet impacts on competition/stress tolerance trade-offs and shifts in distributions are unclear. Ecosystems with strong stress gradients, such as estuaries, allow for space-for-time substitutions of stress factors and can give insight into future climate-related shifts in both resource and nonresource stresses. We tested the stress gradient hypothesis and examined the effect of increased inundation stress and biotic interactions on growth and survival of two congeneric wetland sedges, Schoenoplectus acutus and Schoenoplectus americanus. We simulated sea-level rise across existing marsh elevations and those not currently found to reflect ...


Why Do Different Drought Indices Show Distinct Future Drought Risk Outcomes In The U.S. Great Plains?, Song Feng, Miroslav Trnka, Michael Hayes, Yongjun Zheng 2017 University of Arkansas, Fayetteville

Why Do Different Drought Indices Show Distinct Future Drought Risk Outcomes In The U.S. Great Plains?, Song Feng, Miroslav Trnka, Michael Hayes, Yongjun Zheng

Drought Mitigation Center Faculty Publications

Vigorous discussions and disagreements about the future changes in drought intensity in the U.S. Great Plains have been taking place recently within the literature. These discussions have involved widely varying estimates based on drought indices and model-based projections of the future. To investigate and understand the causes for such a disparity between these previous estimates, the authors analyzed the soil moisture at the near-surface soil layer and the entire soil column, as well as the Palmer drought severity index, the Palmer Z index, and the standardized precipitation and evaporation index using the output from the Community Climate System Model ...

Changes In Arctic Climate And Central U.S. Weather Patterns Is There A Link?, Donald A. Wilhite, Kimberly C. Morrow, Martha Shulski

Drought Mitigation Center Faculty Publications

Earlier snowmelt, decreasing soil moisture, decreased corn yields, increasing extreme precipitation events—these are some of the weather effects currently observed in the central United States that might well have their origin in the rapidly warming Arctic. These and other implications of Arctic warming were among the topics discussed at a fall 2015 workshop, Implications of a Changing Arctic on Water Resources and Agriculture in the Central U.S (Wilhite and Morrow 2016).

The United States assumed chairmanship of the Arctic Council in April 2015, making the workshop topic timely. Given the importance of the Midwest and Great Plains region ...


A Self-Calibrating Runoff And Streamflow Remote Sensing Model For Ungauged Basins Using Open-Access Earth Observation Data, A Poortinga, W Bastiaanssen, G Simons, David Saah, G Senay, M Fenn, B Bean, J Kadyszewski 2017 University of San Francisco

A Self-Calibrating Runoff And Streamflow Remote Sensing Model For Ungauged Basins Using Open-Access Earth Observation Data, A Poortinga, W Bastiaanssen, G Simons, David Saah, G Senay, M Fenn, B Bean, J Kadyszewski

Environmental Science

Due to increasing pressures on water resources, there is a need to monitor regional water resource availability in a spatially and temporally explicit manner. However, for many parts of the world, there is insufficient data to quantify stream flow or ground water infiltration rates. We present the results of a pixel-based water balance formulation to partition rainfall into evapotranspiration, surface water runoff and potential ground water infiltration. The method leverages remote sensing derived estimates of precipitation, evapotranspiration, soil moisture, Leaf Area Index, and a single F coefficient to distinguish between runoff and storage changes. The study produced significant correlations between ...

Data

This dataset includes data used in the publication Kaufman et al., 2017, JGR-Oceans in revision, which investigates how these climatic changes in the Ross Sea, Antarctica, may alter phytoplankton composition, primary productivity and export. A one-dimensional version of the Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification was adapted for use in the Ross Sea (MEDUSA-RS). Glider measurements were used to force MEDUSA-RS, which includes diatoms and both solitary and colonial forms of Phaeocystis antarctica. Model performance was evaluated with glider observations, and experiments were conducted using projections of physical drivers for mid- and late-21st century. Additional scenarios examined ...


Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles 2017 Pomona College

Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles

Pomona Senior Theses

Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster ...

Estimating The Number Of Recreational Anglers For A Given Waterbody, Kevin L. Pope, Larkin A. Powell, Brian S. Harmon, Mark A. Pegg, Christopher J. Chizinski

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Knowing how many anglers use a given body of water is paramount for understanding components of a fishery related to angling pressure and harvest, yet no study has attempted to provide an estimate of the population size of anglers for a given waterbody. Here, we use information from creel surveys in a removal-sampling framework to estimate total numbers of anglers using six reservoirs in Nebraska, USA, and we examine the influence of the duration of sampling period on those estimates. Population estimates (N ± SE) of unique anglers were 2050 ± 45 for Branched Oak Lake, 1992 ± 29 for Calamus Reservoir, 929 ...

Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

To a ten year old boy on a tedious trip across the country side, few views are more fascinating than a wind farm. Massive turbines spin slowly as if to emphasize their preposterous size and magnificence. In an era where increasing global attention is brought to climate change, renewable energy is carving its way into the minds of billions. This once free roadside attraction is now something that in the near future, we must pay and patronize, and this is where my literature begins, how willing are we to pay for renewable energy? Are you willing to pay to give ...
