The Influence Of Invasive Species On Fishers’ Satisfactions, Caroline M. Laplante Dec 2023

The Influence Of Invasive Species On Fishers’ Satisfactions, Caroline M. Laplante

School of Natural Resources: Dissertations, Theses, and Student Research

Invasives species are prevalent and widespread in North America. Outdoor recreational activities, such as fishing, introduce a point in which humans may interact with invasive species and have to adapt their own behaviors. Bigheaded carp in the Missouri River below Gavin’s Point Dam are a group of invasive fish species that were thought to be negatively relating to recreational fishers’ satisfactions. Using a content analysis and an importance-grid, we conclude that invasive species do not strongly relate to recreational paddlefish fishers’ satisfactions. Paddlefish fishers represent a small sub-set of recreational fishers in Nebraska and South Dakota. The content analysis revealed …


Understanding Avidities Of Recreational Activities For People Possessing Fishing Licenses And Residing In Urban Environments, Kyle F. Hansen Dec 2023

Understanding Avidities Of Recreational Activities For People Possessing Fishing Licenses And Residing In Urban Environments, Kyle F. Hansen

School of Natural Resources: Dissertations, Theses, and Student Research

Recreational fishing is one of the world's most popular pastimes, wherein participation is associated with sociodemographic factors. Even so, fishing license sales are declining in the USA in conjunction with a reduction in rural populations as people move to urban areas. Thus, urban areas are constantly growing in population size, population diversity, and geographic size suggesting a need to understand fishing participation in these growing areas. Natural resource managers often use participation to understand recreationists, yet avidity could provide a new way to understand recreationists. The goal of our study is to understand what sociodemographic factors influence the fishing avidity …


Human Dimensions Of Woody Encroachment Management In Nebraska, Emily Rowen Dec 2023

Human Dimensions Of Woody Encroachment Management In Nebraska, Emily Rowen

School of Natural Resources: Dissertations, Theses, and Student Research

Woody plant encroachment (WPE) is a social-ecological problem that will challenge conservation professionals and agricultural producers to adapt their management strategies. This research first examined WPE from the perspective of individual conservation professionals through an online survey. Conservation professionals’ attitudes about adaptation to vegetation transitions, such as WPE, were of interest because these attitudes are one measure of how prepared this group is to respond to WPE. Hypothesized predictors of adaptation attitude were tested through linear regression modeling. These predictors included ecological change, observation of WPE, or risk perception. It was found that risk perception was the strongest predictor of …


Costs Of Wind Erosion In The Northern Agricultural Region, Anne Bennett Dec 2023

Costs Of Wind Erosion In The Northern Agricultural Region, Anne Bennett

Natural resources published reports

Summary

  • To date, the Department of Primary Industries and Regional Development’s (DPIRD) estimated opportunity cost of wind erosion for Western Australia’s (WA) agricultural region has only included the costs of forgone production income and therefore underestimates the broader costs of wind erosion events.
  • This underestimation of costs was the impetus to create a case study to give an indication of the magnitude of the costs of wind erosion from agricultural land.
  • Farmers in the Northern Agricultural Region (NAR) were contacted to seek information about the on-farm costs of wind erosion events that occurred in 2020. Seventeen farmers responded to the …

The Perception Of Natural Resource Management In Nebraska: Efforts For Cross-Boundary Collaborative Management, Daniel Morales

School of Natural Resources: Dissertations, Theses, and Student Research

Nebraska’s agricultural landscapes are rapidly changing, affecting natural resources and their successful management. I utilized two surveys and scenario planning (Chapters 1: statewide survey, 2: local survey, and 3: scenario-planning workshop) to investigate attitudes and perceptions of natural resource management and cross-boundary collaboration. My first objective focused on determining what prevents Nebraskans from addressing natural resources challenges, considering demographics amongst generations and the type of areas they live in (rural versus urban). The second objective focused on whether landowners engaged with their community in managing natural resources. The third objective was to develop alternative future scenarios for the Denton Hills …


Including The Human Dimension Into Resilience Planning For Maine’S Lobster Fishery, Katherine Maltby, Katherine E. Mills Dec 2023

Including The Human Dimension Into Resilience Planning For Maine’S Lobster Fishery, Katherine Maltby, Katherine E. Mills

Maine Policy Review

The American lobster fishery is one of the most valuable in the US but is being affected by climate-driven shifts in lobster availability, impacting people’s ability to harvest the resource and sparking broader adaptation challenges. Since the late 1990s, lobster landings in the Gulf of Maine (GOM) have climbed to record levels while those in Southern New England (SNE) have experienced significant declines. The experiences of SNE lobstermen during these declines can offer important lessons for both individual lobstermen and communities in the GOM, where lobster abundance is currently at high levels but facing future uncertainty given continuing climate trends. …

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 …


Through The Lens Of A Naturalist: How Learning About Nature Promotes Nature Connectedness Via Awe, Shu Tian Ng, Angela K. Y. Leung, Sarah Hian May Chan Dec 2023

Through The Lens Of A Naturalist: How Learning About Nature Promotes Nature Connectedness Via Awe, Shu Tian Ng, Angela K. Y. Leung, Sarah Hian May Chan

Research Collection School of Social Sciences

Environmental educators stress the importance of engaging with the wonders of the Earth in promoting nature connectedness. However, it remains unclear if learning about nature has an incremental effect beyond mere exposure to nature and what psychological mechanism can explain such a learning effect if it exists. To fill this gap, we propose a mediation model in which learning about nature promotes a sense of awe—a self-transcendent emotion associated with the recognition of vastness in nature. A sense of awe, in turn, promotes nature connectedness. Study 1 employed a cross-sectional survey and offered preliminary support for the proposed model, with …

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 Nov 2023

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 Nov 2023

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 …

Solar Radiation Modification Governance In The Context Of Temperature Overshoot, Janos Pasztor Nov 2023

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 Nov 2023

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 …
