River Restoration: Institutions, Boundaries, And Social Ecological Dynamics, Eileen Sylvan Johnson 2015 The University of Maine

River Restoration: Institutions, Boundaries, And Social Ecological Dynamics, Eileen Sylvan Johnson

Electronic Theses and Dissertations

This human dimensions research, consisting of three manuscripts, explores the social and ecological dimensions of river restoration through an examination of the restoration trajectories of the Androscoggin, an impaired system, and the Kennebec, a restored system. Manuscript one examines the influence of biophysical and community attributes and institutional rules on policy stakeholders goals and actions within the two watersheds. For manuscripts one and two, we conducted semi-structured interviews with key informants, assembled documents pertaining to restoration actions, and conducted participant observation at stakeholder meetings. We qualitatively analyzed transcripts and documents. Results suggest that policy stakeholders’ understandings of biophysical and community ...

Simulation Of An Air Cooled Single-Effect Solar Absorption Cooling System With Evacuated Tube Collectors, Mohsen Jahandardoost

UNLV Theses/Dissertations/Professional Papers/Capstones

Consistently increasing CO2 emission and ozone depletion from synthetic refrigerants are serious environmental issues challenging the scientific community. Absorption cooling systems give scope of utilizing low grade energy source for generating cooling effect. Solar energy is one of these low grade energy sources and with considering the fact that cooling demand increases with the intensity of solar radiation, solar refrigeration has been considered as a logical solution.

This thesis consists of two different simulation stages, in the first stage, a single effect lithium bromide absorption cooling system with constant cooling capacity is modeled and the effect of ambient and generator ...

On The Brink: The Melting Of Earth’S Polar Ice Caps, Stephanie Kelley 2015 University of Kentucky

On The Brink: The Melting Of Earth’S Polar Ice Caps, Stephanie Kelley

Kaleidoscope

Research indicates that earth’s polar ice caps are melting at a faster rate than ever before, a product of continued global warming. Unfortunately, side effects of this melting may negatively impact the lives of humans who dwell on this planet. Consequences may include: a significant loss of albedo, a considerable rise in sea levels, damage to aquatic ecosystems, and/or an ice age resulting from the shutdown of major oceanic currents. Although the situation is not yet imminent and the causes not yet pinpointed, the present outlook is too grim to ignore.

Evaluating Sub-Lethal Effects Of Orchard-Applied Pyrethroids Using Video-Tracking Software To Quantify Honey Bee Behaviors, Erin M. Ingram, Julie Augustin, Marion D. Ellis, Blair Siegfried 2015 University of Nebraska-Lincoln

Evaluating Sub-Lethal Effects Of Orchard-Applied Pyrethroids Using Video-Tracking Software To Quantify Honey Bee Behaviors, Erin M. Ingram, Julie Augustin, Marion D. Ellis, Blair Siegfried

Faculty Publications: Department of Entomology

Managed honey bee, Apis mellifera L., colonies are contracted to pollinate fruit and nut orchards improving crop quality and yield. Colonies placed in orchards are potentially exposed to pyrethroid insecticides used for broad-spectrum pest control. Pyrethroids have been reported to pose minimal risk to bees due to their low application rates in the field and putative repellent properties. This repellency is believed to alter foraging behavior with the benefit of preventing bees from encountering a lethal dose in the field. However, sub-lethal exposure to pyrethroids may adversely impact bee behavior potentially resulting in social dysfunction or disruption of foraging.

Environmental Issues In The 1995 Farm Bill, P. G. Lakshminarayan, Bruce A. Babcock 2015 Iowa State University

Environmental Issues In The 1995 Farm Bill, P. G. Lakshminarayan, Bruce A. Babcock

Iowa Ag Review

The perception is growing that U.S. agricultural policy has reached a major turning point increased trade opportunities with GATT, a continued decline in rural population, increased budgetary (fiscal) pressure, and growing environmental concerns are among the primary reasons. Because of these trends, nontraditional interest groups representing urban and environmental interests will play an increasingly important role in shaping future farm legislation.


Implications Of Extending The Consertation Reserve Program For Iowa, John R. Kruse 2015 Iowa State University

Implications Of Extending The Consertation Reserve Program For Iowa, John R. Kruse

Iowa Ag Review

A variety of alternatives have recently been proposed for the future of the Conservation Reserve Program (CRP) program. Among the proposals are: elimination of the program, targeting specific land types for reentry into the program, allowing renewal of all contracts, and redefining the program to bid land in for a one lime permanent easement payment.


The Conservation Reserve Program, John R. Kruse 2015 Iowa State University

The Conservation Reserve Program, John R. Kruse

Iowa Ag Review

The Conservation Reserve Program (CRP) was originally created in the 1985 Food Security Act to "assist owners and operators of highly erodible cropland in conserving and improving the soil and water resources of their farms or ranches."

The near future of ethanol production in Iowa appears to be on safer footing than it was just a few weeks ago, but nothing is certain given the political volatility in Washington.


The Agricultural Footprints On The Environment, Philip Houtz 2015 University of Kentucky

The Agricultural Footprints On The Environment, Philip Houtz

Kaleidoscope

Industrialized agricultural systems have given America a convenient and affordable means to supply a surplus of food products to its citizens. Transgenic technology, synthesized fertilizers, advanced pesticides, concentrated animal feeding operations (CAFOs), and the use of farm machinery have all contributed to humanity’s ability to feed the world’s rapidly growing population. However, the energy-intensive food operation of today may not be as ideal as we assume. Fossil fuels are burned to meet the energy requirements for the continual production of large quantities of fertilizer and to keep farm machines operational. Fertilizer and pesticide runoff from farmland ultimately drains ...


The Look Of The "New" Conservation Reserve Program, Steven L. Elmore, Darnell B. Smith 2015 Iowa State University

The Look Of The "New" Conservation Reserve Program, Steven L. Elmore, Darnell B. Smith

Iowa Ag Review

In recent years some prognosticators envisioned that the amount of acreage enrolled in the Conservation Reserve Program (CRP) would shift from west to east. This expectation is based on a perceived increase in the social valuation for water quality versus other CRP benefits. Some west-to-east shifts did occur after CRP rules were revised under the 1990 Farm Bill. However. the latest sign-up results reveal the opposite- an east-to-west movement.

Capstone Collection

This research paper focuses on how the power crisis is impacting the social and economic livelihoods of the citizens in the Santo Domingo, Dominican Republic. The Dominican Republic, an island located in the Caribbean, for years has been in a vulnerable state due to its exposure to flooding caused by tropical storms. Coastal communities are not only vulnerable to flooding issues but electrical as well. Citizens must adapt to frequent power outages that occur multiple times during the week and for long period of times. Therefore, it is important to understand the various ways power outages may be impacting social ...


Is Soil Quality Linked To Psnp Graduation In East And West Hararghe, Ethiopia?, Elizabeth Gladding 2015 SIT Graduate Institute

Is Soil Quality Linked To Psnp Graduation In East And West Hararghe, Ethiopia?, Elizabeth Gladding

Capstone Collection

Many households in Ethiopia have struggled to remain food secure and meet their nutritional needs. In response to chronic food insecurity the Ethiopian government developed the Productive Safety Net Program (PSNP) to provide support to households in the form of food or cash transfers in exchange for public service work. The idea of the program is that households will develop their livelihoods through the public work and eventually become self-sufficient, food secure and graduate from the PSNP.

Some households graduate from PSNP in a shorter time than others, attributing to many different factors. This study looks at soil quality as ...


Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman 2015 Colby College

Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman

Journal of Environmental and Resource Economics at Colby

With global population increasing faster than ever, the need to protect land from development is at an all-time high. This paper seeks the measure the public preference for a new national park located in northern Maine. A national park will both protect the land and inject a much-needed economic stimulus to the surrounding communities. The study uses the choice experiment valuation method to quantify its results. Through this revealed preference we can quantify which characteristics are most important to the public so that these characteristics may be considered if the project is ever approved.

Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, Gregory Ladd, Jason Buco

Journal of Environmental and Resource Economics at Colby

Many studies have been conducted analyzing the economic impact of golf courses on the local communities. These studies examine economic impacts of tournaments, endorsements, and vacation expenses of the major golf courses in the United States. However, there is little research conducted on the environmental impact of Golf courses, specifically in Maine. This paper performs a hedonic pricing analysis using housing prices in proximity to golf courses and compares it to the valuation of various land types in Maine. Housing prices were collected in the towns of Auburn, and North Yarmouth both near and distant from the local golf course ...


Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. DeFrancis 2015 Colby College

Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis

Journal of Environmental and Resource Economics at Colby

The global agriculture sector is responsible for close 20% of the aggregate anthropogenic greenhouse gas (GHG) emissions emitted since the start of the industrial age. Much of these emissions are attributed to the degradation of soils due to land use change when native ecosystems were converted to agricultural fields. Soil organic carbon (SOC) has been found to decrease in temperate soils when the native (such as a forest or grassland) ecosystem is replace by croplands. The aggregate amount of organic carbon stored in soils globally is estimated be 3.3x the size of the atmospheric carbon pool. Further soil degradation ...
