The Effects Of Property Rights On Ocean Resources: Two Possible Solutions To The Tragedy Of The Commons, Nathan David Miller
The Effects Of Property Rights On Ocean Resources: Two Possible Solutions To The Tragedy Of The Commons, Nathan David Miller
Honors Program Theses
Property rights affect how people use resources. Enforcement regimes are able to set clear laws with well-defined property rights. Governments set laws for conservation and economic success. Ocean resources suffer from overuse. Industry and the environment both benefit from regulations that promote ocean conservation. This paper will analyze how the current state of ocean property rights leads to the depletion of ocean resources. Though there are many possible solutions to overfishing, I will analyze two potential solutions to overexploitation in the commercial fishing industry: marine protected areas (MP As) and individual transferable quotas (ITQs ). A synthesis of previous research …

Mathematical Modeling Of Fluid Spills In Hydraulically Fractured Well Sites, Oluwafemi Michael Taiwo
Graduate Theses and Dissertations
Improved drilling technology and favorable energy prices have contributed to the rapid pace at which the exploitation of unconventional natural gas is taking place across the United States. As a natural gas well is being drilled, reserve pits are constructed to hold the drilling fluids and other materials returned from the drilling process. These reserve pits can fail, and when they do, plant and animal life of the surrounding area may be adversely affected. This project develops a screening tool for a suitable location for a reserve pit. This work will be a critical piece of the Infrastructure Placement Analysis …

Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis, Phillip Mykleby
Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis, Phillip Mykleby
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Vegetation and climate both play integral roles in water availability, particularly for arid to semi-arid regions. Changes in these variables can lead to extreme shortages in water for regions that rely on water for crop irrigation (i.e., the Great Plains). The objective of this study is to evaluate the impacts of vegetation on water availability in the Republican River basin in central Nebraska. Decreases in streamflow have been observed in the river basin for many years and, as a result, an invasive riparian plant species (Phragmites australis) is being removed in an effort to reduce evapotranspiration and reclaim …

Predictors Of Insect Diversity And Abundance In A Fragmented Tallgrass Prairie Ecosystem, Kody M. Unstad
School of Natural Resources: Dissertations, Theses, and Student Research
Despite providing many services, the tallgrass prairie and its ecological community is one of the most endangered ecosystems in North America. Remaining habitat exists as remnants in a highly-fragmented landscape. To make informed conservation decisions we need to better understand the effects of this fragmentation. Using the ecologically important insect groups, ants and ground beetles, this study provides baseline data on the biological diversity of southeast Nebraska prairies and investigates what management, landscape, and habitat characteristics affect them. Pitfall trap sampling was conducted in 23 tallgrass remnants scattered throughout the Southeast Prairies Biologically Unique Landscape in 2010 and 2011. Multi-model …
Fourteen Years Of Sustainable Charcoal: The Case Of Ankitsakalaninaomby, Dan Raudonis
Fourteen Years Of Sustainable Charcoal: The Case Of Ankitsakalaninaomby, Dan Raudonis
Independent Study Project (ISP) Collection
All over the world, different sources of energy are harnessed by populations looking to fulfill their needs, be it electricity, heating, or cooking. In Madagascar, fuel wood and wood charcoal provide the bulk of daily energy needs – for over 85% of the population they are the only available sources of domestic energy (GREEN-Mad 6). These two sources provide a cheap alternative to other fuels such as natural gas, which can be more than three times as expensive as charcoal (GREEN-Mad 51). In an impoverished country such as Madagascar, where 90% of the population live on less than two US …
Implications For Old-Field Restoration: Diversity And Abundance Of Arbuscular Mycorrhizal Fungi In Soils Of Restored York Gum (Eucalyptus Loxophleba Subsp. Loxophleba) Sites Vs. Remnants., Jessica Wong
Independent Study Project (ISP) Collection
Arbuscular mycorrhizal fungi (AMF) may be critical to the restoration of ecosystem function in old-fields. Whether the diversity of the plant community is promoted by the AMF community or is the driving force of AMF diversity is unknown. We investigated two questions in the context of old-field restoration in southwestern Australia: 1) Does restoration of the plant community achieve the restoration of AMF and 2) Is AMF species diversity and abundance influenced by the plant species composition? Our study sites were located in the Ridgefield Experiment in the University of Western Australia’s “Future Farm”. Soil samples were collected from beneath …
Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea
Independent Study Project (ISP) Collection
Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …

When asked what the top three issues of the Las Vegas region were, the reply was “water, water, water!" This was the result of a survey done a few years ago of Las Vegas Valley TV anchors. The reason for this response is that sustainability of the urban environments requires sufficient water resources as does population growth. With the advent of global climate change, this resource is in danger. Water flow and mountainous ice packs are impacted by this change in climate there by impacting the amount of water the the region. This is compounded over time as the population …

West Of Eden: Resource Wars And Nature-Cultures In The American West, Scout Calvert
University of Nebraska-Lincoln Libraries: Faculty Publications
The richness and variety of the western landscape is what is at stake in hot political contests for the resources of the West: much of this public land is available to economic activity, including for mining, grazing, logging, and recreation. These uses threaten to outpace the land’s ability to renew these resources along with others, like air and water. Now in the first decade of the millennium with a new environmental awareness emerging partly from media coverage of global warming and peak oil, The American West at Risk offers a wide-ranging look at the degradation of the environment in the …

Global Monthly Water Scarcity: Blue Water Footprints Versus Blue Water Availability, Arjen Y. Hoekstra, Mesfin Mekonnen, Ashok K. Chapagain, Ruth E. Mathews, Brian D. Richter
Daugherty Water for Food Global Institute: Faculty Publications
Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values. We analyzed 405 river basins for the period 1996–2005. In 201 basins with 2.67 billion inhabitants there was severe water scarcity during at least one month of the year. The ecological and economic consequences of increasing …

The Water Footprint Of Humanity, Arjen Y. Hoekstra, Mesfin Mekonnen
Daugherty Water for Food Global Institute: Faculty Publications
This study quantifies and maps the water footprint (WF) of humanity at a high spatial resolution. It reports on consumptive use of rainwater (green WF) and ground and surface water (blue WF) and volumes of water polluted (gray WF). Water footprints are estimated per nation from both a production and consumption perspective. International virtual water flows are estimated based on trade in agricultural and industrial commodities. The global annual average WF in the period 1996–2005 was 9,087 Gm3 ∕y (74% green, 11% blue, 15% gray). Agricultural production contributes 92%. About one-fifth of the global WF relates to production for export. …
