The Transaction Costs Of Federal Environmental Policy Changes: The Effects Of The Temporary Covid-19 Cwa Rollback On Local Water Systems, Jesse Lee Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

An institutional dilemma exists between the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). US surface waters are protected from point-source pollution by the CWA. Community Water Systems (CWSs) that draw from these surface waters for potable purposes are required to treat that water to a level that meets SDWA health standards. Therefore, decreases in CWA regulations could lead to surface water quality declines and, thus, higher SDWA compliance costs for CWSs. This area of inquiry has become increasingly relevant due to Trump-era executive actions to try to decrease the federal government's role in multiple environmental policies, …

Congressional Preferences And The Advancement Of American Nuclear Waste Policy, Rhoel Gonzales Ternate

UNLV Theses, Dissertations, Professional Papers, and Capstones

The problem of nuclear waste disposal has existed since the time of the Manhattan Project in World War II. Although there exist a number of technological hurdles, the main cause that has consistently plagued a solution to nuclear waste has been the politics behind it. This thesis attempts to add to the political literature behind nuclear waste disposal by examining the nuclear waste disposal preferences of members of the United States House and Senate. It then compares and contrasts those preferences with a report by President Obama's Blue Ribbon Commission on America's Nuclear Future. The hope was to determine if …

Understanding Urban Sustainability And Quality Of Life: A System Dynamics Approach, Abby Elizabeth Beck

UNLV Theses, Dissertations, Professional Papers, and Capstones

For an urban area to be sustainable, its resources cannot be depleted faster than they can replenish. If an urban area is to provide a high quality of life (QOL), it must offer and maintain an amenity package that satisfies its resident's preferences. Past studies on these topics all have a common thread: sustainability and QOL both pertain to people's relationship to capital. Capital is something that can accumulate and add value to a person or society. If sustainability and QOL are a function of people's relationship with capital, how they use it, deplete it, replenish it and transform it …

Redefining Security In Sub-Saharan Africa, Winta Sintayehu Gebremariam

UNLV Theses, Dissertations, Professional Papers, and Capstones

New and challenging threats to humans are currently on the rise. These threats to human well being have been neglected and ignored within the traditional conception of security. Security studies have mainly focused on traditional threats, mostly military and political. Although still important, this perspective lacks the ability to address nontraditional threats that are killing and injuring millions each year. Each year, millions die of diseases such as HIV/AIDS, tuberculosis, malaria, hunger, and water related diseases among others. Although these threats are widespread throughout the world, Sub-Saharan Africa bears the brunt of these threats. This thesis proposes an ecological approach …

Climate Change In Rural Nevada: The Influence Of Vulnerability On Risk Perception And Environmental Behavior, Ahmad Safi

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this research, I examine the impact of vulnerability on risk perception, stated willingness to adopt individual mitigation behavior, and support for climate change mitigation policies. My major research question is, "Does vulnerability to climate change increase risk perception, encourage more energy-efficient individual behavior, and enhance support for climate change mitigation policies?" But to understand the role of vulnerability I also pursue answers to questions regarding its three components: Physical vulnerability; sensitivity and adaptive capacity. I investigate the following sub-questions:

• Do physical vulnerability, and sensitivity to climate change increase risk perception, encourage more energy-efficient individual behavior, and enhance support for …

Estimating Wildfire Potential On A Mojave Desert Landscape Using Remote Sensing And Field Sampling, Peter F. Van Linn Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

Landscape level wildfire prediction can be used to allocate wildfire resources and guide land management practices. Wildfire prediction in arid habitats in the Southwestern United States is of specific concern because of the negative ecological impacts of fire on desert habitats and the current lack of accurate fire prediction tools for such areas. This study examines the ability to predict previous fire occurrences and estimate future fire potential using satellite imagery and on the ground field survey techniques along with ignition potential data (lightning strikes and distance to roads), topographical data (elevation and aspect), and climate information (maximum and minimum …

Consensus On The Colorado: Issues In The Allocation Of A Limited Resource, Jeffrey D. Tilton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to identify current issues in water allocation in the Lower Colorado River Basin and to locate existing areas of consensus among its stakeholders. Surveys, both paper and web-based provided the data required to measure overwhelming agreement on issues. The data analysis served to locate the areas of agreement within and between interest groups. While overwhelming agreement between all groups proved to be a relatively rare occurrence, the existence of issue specific agreement between two or more groups was more common than expected. Accord was demonstrated in all four major areas: allocation, augmentation, conservation, and …

Design Standards Within Constructed Wetlands For The Reduction Of Mosquito Populations In Clark County, Nevada, Phillip C. Bondurant

UNLV Theses, Dissertations, Professional Papers, and Capstones

Wetlands are considered one of the most productive ecosystems in the world and provide many benefits to the environment. However, the slow moving and sometimes stagnant water created by the vegetation in the wetland creates an ideal environment for the proliferation of mosquitoes. Mosquitoes are the most important insect disease vector worldwide. The presence of mosquitoes within wetlands increases the risk of disease transmission among workers and visitors creating a public health concern. Effective design standards aimed at reducing mosquito breeding habitat should be implemented during the construction and planning phase of wetland development to effectively reduce the mosquito populations. …

Perception Of Ecological Risk To Water Environments And How It Affects Water Consumption And Water Resource Management In Southern Nevada, Tanju Kiriscioglu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate is harsh in southern Nevada where there is (and has been) a drought alert in effect for over a decade now (Kerr, 2007; Southern Nevada Water Authority, 2009). Las Vegas Valley is a major center of population in the region (1.9 million people), receiving only 4.5 inches of average annual precipitation yet in need of securing more water resources in the near future (SNWA, 2009). Water resource management in southern Nevada is a challenge, especially when 90% of the area’s water needs are met by a single source, the Colorado River, the flow rates of which have been in …

Adaptive Management Of Complex Environmental Problems – Comparison Of National Nuclear Waste Management Policies, Carmel Letourneau

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many of today's challenging environmental problems, to the point of manifesting themselves on a scale that has global, political consequences, likely result from long-term evolutionary developmental processes. The degree to which humans can manage the evolution of these problems remains an open question. Faced with such challenges, since the mid 1980s, an increasing number of scholars have developed other forms of management, in particular, adaptive management. Scholars suggest that improving the performance of adaptive management requires that environmental problems be understood as 'complex', open, evolving systems of interacting social and environmental subsystems. To date, narrative has been the primary approach …

The Integration Of Biomimicry Into A Built Environment Design Process Model: An Alternative Approach Towards Hydro-Infrastructure, Timothy Lee Albertson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current methods and processes that support the planning, design and construction of a sustainable built environment include ambiguous principles (Roseland 2000), lack feedback loops (Van Bueren and Jong 2007) and lack a common language between disciplines (Brandon et al 1997). As a result of 3.8 billion years of "research and development" (evolution), nature provides a set of design blueprints that may be used to guide us to create elegant, sustainable, and innovative designs for human technologies (Benyus 1997). The field of biomimicry analyzes nature's best ideas and adapts them for human use (Benyus 1997). The built environment could benefit from …

Transforming Space Into Place: Development, Rock Climbing, And Interpretation In Red Rock Canyon National Conservation Area, 1960-2010, Megan Sharp Weatherly

UNLV Theses, Dissertations, Professional Papers, and Capstones

Though Americans tend to view wilderness as separate from nature, environmental historians have argued that wilderness is a cultural construct more than a quantifiable geographic category. Red Rock Canyon National Conservation Area (NCA), a 195,000-acre tract located west of Las Vegas, Nevada, is one such cultural construction. Since 1960, this BLM-managed parcel has served as a local and regional expression of broader, national trends in outdoor recreation, interpretation, and development and thereby forced visitors to engage (often unknowingly) in a cultural dialogue about consumerism, technology, and identity. With information from newspapers, archival collections, oral histories, and government documents, this thesis …

The Environmental And Economic Benefits Of Highway Access Management: A Multivariate Analysis Using System Dynamics, Dan Andersen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Better management of highway operations can be achieved, in part, by controlling vehicular access to adjacent properties and cross streets. This tactic, referred to as access management, has proven safety and operational benefits. However, doubts remain regarding its environmental and economic benefits.

I hypothesize that one environmental indicator, carbon emissions, will decrease with proper access management. Controlling access increases the speed at which vehicles travel, improving fuel efficiency and reducing carbon emissions. My hypothesis relative to financial impacts is that access management will neither help nor harm businesses. Controlling access can reduce travel time which has the effect of increasing …

Understanding The Motivations Of Rock Climbers: A Social Worlds Study, Amy Miller Ansari

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rock climbing affects public lands through erosion, destruction of vegetation, and disturbance to historical sites. Minimum impact messages can help reduce impacts but requires understanding characteristics of the message recipient. The purpose of this study was to understand the motivations of rock climbers to help land managers design more effective minimum impact messages. This study assesses the motivations of rock climbers using a social worlds approach, focusing on the sub-worlds of. traditional climbers, sport climbers, and boulderers. I found that traditional climbers are most motivated to pursue a wilderness experience, climb in a natural wilderness setting, and climb in quiet …

Streamlining The National Environmental Policy Act Reporting Requirements: A Hard Look At The Healthy Forests Initiative, Jeffrey Alan Geller

UNLV Theses, Dissertations, Professional Papers, and Capstones

The U.S. Forest Service (USFS) has implemented the Healthy Forests Initiative (HFI) (2002), which streamlines the NEPA process for proposed forest fuel reduction projects. A key question is whether the USFS’s streamlined NEPA process produces an adequate environmental document and fulfills regulatory requirements. This thesis evaluates whether the streamlined approach practiced by the USFS under the HFI satisfies the NEPA requirements. A review of four streamlined documents assesses whether these requirements are met. The following NEPA requirements in particular are explored for each project to determine whether the NEPA requirements are met: consideration of a reasonable range of alternatives to …

An Exploratory Study That Examines Perceptions, By The Regulated Community, On The Effectiveness Of Air Quality Permitting For Clark County, By The Department Of Air Quality And Environmental Management, Scott Jelinek

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Clean Air Act of 1970 (CAA) made the Environmental Protection Agency (EPA) responsible for establishing and maintaining federal programs that control air quality. In turn, each state was delegated responsibility for air quality within its borders, although this responsibility may be shared with Native Americans or tribal lands. In many states, jurisdiction has been delegated to regional or local agencies that are then responsible for air quality in their respective air basins. Even though terrain or water bodies define the physical boundaries of air basins, they are usually designated by County boundaries for regulatory convenience (Wooley, David R., 1997).

Remote Sensing And Geographic Information Systems For Decision Analysis In Public Resource Administration: Case Study In A Southwestern Watershed, William G. Kepner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alternative futures analysis is a scenario-based approach to regional land planning that attempts to synthesize existing scientific information in a format useful to community decision makers. Typically, this approach attempts to investigate the impacts of several alternative sets of choices preferred by representative stakeholder groups relative to selected environmental or economical endpoints. Potential impacts from each of the scenarios are compared to current conditions of the region in terms of a set of processes that are modeled within a geographic information system. Future conditions are generally examined from the perspective of a recent baseline condition (versus empirically determined using a …

Examination Of The Bureau Of Land Management's Implementation Of The Wild, Free-Roaming Horse And Burro Act At Red Rock National Conservation Area, Christine E. Brehm

UNLV Theses, Dissertations, Professional Papers, and Capstones

For unknown reasons horses went extinct on the North American continent approximately ten thousand years ago and were subsequently reintroduced by Spanish settlers in the 1400's. As European settlers moved westward, horses were perceived as competition for grasslands and their numbers were curtailed. Wild horses were granted Federal protection in 1959 with the passage of the 'Wild Horse Annie' law and further protected with the passage of the Wild, Free-Roaming Horse and Burro Act of 1971. Through the Department of the Interior, the Bureau of Land Management was charged with management of wild horses on public lands. Physical searches of …

Golf Courses In Southern Nevada Will Significantly Impact The Water Management Efforts By Using Recycled Water Rather Than Potable Water To Irrigate Their Turf, Sean D. Ainsworth

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the number of people continually move to the Las Vegas Valley and take up residence, the possibility of "running out of water" can become a reality. Having large water users (i.e. golf courses) irrigate their turf with recycled water, they will significantly impact the water management efforts in the Las Vegas Valley. When each course is irrigating their turf with recycled water, this will help ease the drinking water demand in the valley, especially during the peak demand season (summer).
