Multi-Objective Water Management In Idaho's Henrys Fork Watershed: Leveraging Reservoir Operation And Groundwater Pathways To Benefit Aquatic Habitat, Christina N. Morrisett
All Graduate Theses and Dissertations, Fall 2023 to Present
Multi-user water management is a challenging arena further complicated by climate change. This research is based in the Henrys Fork, Snake River, Idaho—an agricultural watershed that exemplifies those throughout the semi-arid American West. This dissertation uses an integrated approach that considers groundwater-river relationships, farm-scale decisions and basin-scale outcomes, upstream reservoir operation for downstream aquatic habitat, water rights, and collaborative stakeholder management to identify drought adaptation strategies accordingly.
Chapter 2 uses an interdisciplinary approach to quantify how improvements to irrigation efficiency at the farm-scale (i.e., converting from flood to sprinkler irrigation) can add up to affect hydrology at the landscape-scale and …
Inundated Vegetation Response To Ongoing Restoration And Its Impacts On Fish Community Structure, Emmanuel J. May
Inundated Vegetation Response To Ongoing Restoration And Its Impacts On Fish Community Structure, Emmanuel J. May
All Graduate Theses and Dissertations, Fall 2023 to Present
Shallow lake ecosystems and their associated wetland habitats globally are subject to non-native species introductions, nutrient loading, and water level fluctuations, each of which can decrease vegetated habitat availability, exposing vulnerable native aquatic species to predation. Managers are frequently tasked with mitigating native species declines by restoring vegetation considered crucial for their survival. However, restoring vegetation can be challenging in the presence of multiple stressors, requiring managers to assess the relative importance of the different stressors limiting vegetation recovery.
Utah Lake is a large shallow lake subject to multiple stressors and has shifted from a mesotrophic lake with abundant aquatic …
Fire And Flow: Assessing The Long-Term Effects Of Wildfires And Impact Of High Flow Events On Phosphorus Concentrations In Mountain Streams, Rachel Watts
All Graduate Theses and Dissertations, Fall 2023 to Present
Climate change has led to significant shifts in the Earth’s weather patterns, often leading to longer, more intense droughts, irregular but extreme storms, and more severe wildfires with longer burn durations. These weather pattern changes have frequently led to shifts in ecosystem dynamics, impacting aspects such as nutrient flux, species diversity, and overall habitat health. Regarding nutrient flux specifically, changes in phosphorus (P) concentrations can negatively impact stream systems as elevated levels can lead to toxic algal blooms, which can cause habitat degradation, loss of usable recreational areas, and large fish kills. A common trigger of these P spikes is …
Movement Patterns Of A Federally Endangered Minnow In A Fragmented Desert River, Martinique J. Chavez
Movement Patterns Of A Federally Endangered Minnow In A Fragmented Desert River, Martinique J. Chavez
All Graduate Theses and Dissertations, Fall 2023 to Present
Fishes are unified in their need to move within the systems they occupy, and their movement patterns can be fundamental to their ecology and survival. Many large rivers in North America are fragmented by dams that modify natural flow regimes, compromise connectivity, and imperil freshwater fishes dependent on unrestricted movement in order to complete their life history. Coincident with widespread river fragmentation, are the declines of numerous endemic desert fishes in the American southwest. The Rio Grande Silvery Minnow (Hybognathus amarus, RGSM), has experienced a 95% reduction in its historical range and is now restricted to a highly …

Development, Voice, And Vulnerability: A Rhetorical Analysis Of The Policy-Making Discourse Regarding The Paris Agreement As An Organizational Response To Climate Change, David Almanza-Canas
UNLV Theses, Dissertations, Professional Papers, and Capstones
On December 12, 2015, the Paris Agreement was officially ratified by 196 sovereign entities. This treaty represents a global call to action to ameliorate the impact of human activities on our environment, and it creates a means of cooperation through financial support and transparent industrial practices with the goal of promoting accountability across the world. This treaty and the discourse surrounding it present fertile ground for the academic understanding of persuasive practices in policy-making. By examining the rhetorical implications of the Paris Agreement as a global policy, scholars can gain new insight about the communities represented in the conversation as …
Beyond Corporate Greenwashing: Discourse Of A 'Just' Electric Energy Transition Materialized At The Thacker Pass Lithium Mine, Laekyn Kelley
Beyond Corporate Greenwashing: Discourse Of A 'Just' Electric Energy Transition Materialized At The Thacker Pass Lithium Mine, Laekyn Kelley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Thacker Pass in Northern Nevada is a rich desert ecosystem with spiritual significance to local Indigenous peoples, and it is also the site for what will be, for now, the United States’ largest open-pit lithium mine. Lithium is one mineral constituent of electric batteries which are essential to current U.S. electric energy transition policy, a transition which policymakers and other public groups have called on to be done in a way which is just. However, what exactly a just electric energy transition looks like in places like Thacker Pass is under continued negotiation in theoretical and practical senses. Existing research …

Painting Our Treescapes: A Visual, Gretel Olson, Ingrid Olson, Stephanie Schuurman-Olson
Occasional Paper Series
Two children (ages 6 and 9) represent an afternoon spent in their urban, wintery treescape through visual art, photo documentation, and written narrative. The first piece, "My Imaginary Forest", considers the seasons, animals, and issues of artistic representation of nature. The second piece describes the relationship between a favourite tree and a child, and considers others -- both present and future -- who also occupy "Our Knotty Tree". All of the words, visual art, and photo selection are those of the children.
Sustainable Energy Distribution Methods At The Azraq And Za’Atari Refugee Camps In Jordan: A Refugee Perspective, Lucie Lagodich
Sustainable Energy Distribution Methods At The Azraq And Za’Atari Refugee Camps In Jordan: A Refugee Perspective, Lucie Lagodich
Capstone Collection
The looming climate change crisis requires research and development of mitigation strategies to protect those most vulnerable. This study uses semi-structured interviews to capture the refugee perspective of the successes and shortcomings of large-scale solar farm projects installed at the Azraq and Za’atari Syrian refugee camps in the west and north of Jordan, respectively. These perspectives may be utilized to improve each camp's current renewable energy distribution system. Results suggest that at both camps the current renewable energy systems are deeply flawed with limited hours with rampant distrust among camp residents in the management of the solar farms. Most refugees …

Data From: Root Distributions Predict Shrub-Steppe Responses To Precipitation Intensity, Andrew Kulmatiski, Karen H. Beard
Browse all Datasets
Precipitation events are becoming more intense around the world, changing the way water moves through soils and plants. Plant rooting strategies that sustain water uptake under these conditions are likely to become more abundant (e.g., shrub encroachment). Yet, it remains difficult to predict species responses to climate change because we typically do not know where active roots are located or how much water they absorb. Here, we applied a water tracer experiment to describe forb, grass, and shrub root distributions. These measurements were made in 8 m by 8 m field shelters with low or high precipitation intensity. We used …

Results Of Cop27 And Expectations For Cop28, Cecilia Kinuthia-Njenga, Fareed Yasseen
New England Journal of Public Policy
Since 1995, government representatives from around the world have gathered nearly every year for the United Nations Conference of the Parties (COP) to advance work on multilateral agreements and to provide a way forward in tackling the significant challenges of climate change. The last of these conferences took place on November 6–20, 2022, in Sharm el-Sheikh, Egypt.
COP27 brought together more than 35,000 people from across the globe to deliberate on important actions for addressing the climate. Hailed as the “African COP” and “Implementation COP,” it raised expectations that decisions from previous conferences, reflecting the needs and priorities of the …
The Perfect Is The Enemy Of The Good: Carbon Credits And Funding For Decarbonization In Developing Countries, Andrew A. Bernstein
The Perfect Is The Enemy Of The Good: Carbon Credits And Funding For Decarbonization In Developing Countries, Andrew A. Bernstein
New England Journal of Public Policy
Carbon credits issued in the voluntary carbon market are an important source of funding for projects in developing countries designed to reduce greenhouse gas emissions, such as forest preservation and renewable energy. Beyond their potential to provide billions of dollars of private sector financing for decarbonization, carbon credits can generate economic opportunity, employment, and biodiversity. But they are controversial, mainly (but not only) because it is difficult to confirm and to quantify their emissions benefits. This article argues that policymakers should nonetheless support voluntary carbon market growth, so long as companies use carbon credits to mitigate emissions they cannot avoid …
Joint Global Responsibility Fund For Climate, Conservation, And Communities: A Proposed Innovative Tax-Based Funding Mechanism, Tamar Ron
New England Journal of Public Policy
Nature-based solutions address biodiversity loss, climate change, and societal challenges at the local, national, regional, and global levels. The costs of their conservation, however, are mostly local and national in nature. Confronting the rolling dual crisis of biodiversity loss and climate change requires us to recognize nature’s intrinsic value. Moreover, we must find practical ways for their monetary valuation to be channeled as payment for the services of conservation custodians. It is suggested here to translate the value of natural assets and the understanding of the local costs and global benefits of their conservation, into an innovative and ambitious funding …

In this article Stéphanie Heckman examines the process and outcomes of her graphic recording work and other forms of visual practice in the context of UN climate negotiations, reflecting on three years of collaboration with the UN Climate Change Secretariat, particularly during the eighteen-month Global Stocktake process. After a review of the history and science behind visual storytelling, she analyses one of the graphic recordings made for the third meeting of the Technical Dialogue of the Global Stocktake through the lens of Kelvy Bird’s ‘Levels of Scribing’ model. Drawing on comments from delegates at COP27 in Sharm el-Sheikh, Egypt and …
Solar Radiation Modification Governance In The Context Of Temperature Overshoot, Janos Pasztor
Solar Radiation Modification Governance In The Context Of Temperature Overshoot, Janos Pasztor
New England Journal of Public Policy
As the climate crisis escalates, governments—and recently even those in the wealthier countries in the Global North—are struggling to manage the impacts we are experiencing around the world in frightening abundance, including record-setting temperatures, fires, floods, and glacial and ice melt. Behind closed doors, policymakers are concerned as they contemplate the increasing likelihood, even under the most ambitious emission reduction pathways, that the world will overshoot the goal agreed upon in the Paris Agreement to limit global average temperature rise to 1.5oC beyond pre-industrial levels.
It is in this “overshoot context” that interest is growing in an emerging, potentially supplementary …
Cop27 And The New Rise Of The Global South, Janice Golding
Cop27 And The New Rise Of The Global South, Janice Golding
New England Journal of Public Policy
Developing countries require direct and indirect financial and non-financial assistance to address the climate crisis. The COP27 announcement of a new Loss and Damage Fund as well the unveiling of the Bridgetown Initiative collectively hold substantial promise to alter the course of climate multilateralism. The outcome of COP27 has presented unprecedented opportunities for the Global South to build global solidarity for climate justice, but the path ahead will not be easy. Materialization of support to developing countries may be, at best, not sustainable, or at worst, unforeseeable without consistent application of principles and values enshrined in historic, moral accountability for …
The Role Of Carbon Management Technologies In Meeting Net Zero, Ali Al-Saffar
The Role Of Carbon Management Technologies In Meeting Net Zero, Ali Al-Saffar
New England Journal of Public Policy
The pathway toward implementing the changes necessary in the energy sector to keep global temperature rises from breaking through catastrophic barriers is narrow and tenuous and will require a range of zero- and low-carbon technologies to be dispatched at a speed and scale that is virtually unprecedented. Decarbonization through renewables, matched with the more efficient use of energy in the end-use sectors will play a large part. But there is growing realization that there will be residual fossil fuel use long into the future, and that the emissions from the burning of these fossil fuels in power plants and factories …
