Enhancing The Federal Natural Resource Damage Assessment And Restoration Process Through Bayesian Networks: A Case-Study On The Little Mississinewa River, Indiana, April D. Reed
WWU Graduate School Collection
The Federal Natural Resource Damage Assessment and Restoration (NRDAR) program gives Tribes and certain government agencies the authority to assess injury to natural resources and to pursue and implement compensatory action for any resources lost or injured due to unlawful releases of chemicals into the environment. This study was centered around the development of a Bayesian network (BN) decision support tool tailored to the needs of NRDAR practitioners. The goal was to design a probabilistic BN tool that could lend quantitative insight into natural resource injury. A case study was used to develop and demonstrate the tool’s functionality and propriety …
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 …

A Look At Land Cover Classification Methods In Northern California With The Use Of High Spatial Resolution Geospatial Data, Lucila Corro
Cal Poly Humboldt theses and projects
Land use and land cover (LULC) mapping plays a vital role in understanding the state of the world, showing us a visual representation of the natural and anthropogenic features covering our planet. Northern California in the United States is home to many critical habitats that provide for a variety of endemic and some threatened and engendered species, making it an area of particular concern to better understand and monitor. There is a greater need to identify specific methods for vegetation modeling in Northern California due to its unique species; to do this we examined two case studies with the following …
Can A Remote Sensing Approach With Hyperspectral Data Provide Early Detection And Mapping Of Spatial Patterns Of Black Bear Bark Stripping In Coast Redwoods?, Shayne R. Magstadt
Can A Remote Sensing Approach With Hyperspectral Data Provide Early Detection And Mapping Of Spatial Patterns Of Black Bear Bark Stripping In Coast Redwoods?, Shayne R. Magstadt
Cal Poly Humboldt theses and projects
The prevalence of black bear (Ursus americanus) bark stripping in commercial redwood (Sequoia sempervirens) timer stands has been increasing in recent years. This stripping is a threat to commercial timber production because of the deleterious effects on redwood tree fitness. This study sought to unveil a remote sensing method to detect these damaged trees early and map their spatial patterns. By developing a timely monitoring method, forest timber companies can manipulate their timber harvesting routines to adapt to the consequences of the problem. We explored the utility of high spatial resolution UAV-collected hyperspectral imagery as a …
Modeling Community Resource Management: An Agent-Based Approach, Maya M. Lapp
Modeling Community Resource Management: An Agent-Based Approach, Maya M. Lapp
Senior Independent Study Theses
As the human population continues increasing rapidly and climate change accelerates, resource depletion is becoming an international problem. Community-based natural resource management (CBNRM) has been suggested as a method to conserve resources while simultaneously empowering traditionally marginalized communities. Because classical equation-based modeling methods fail to capture the complexity of CBNRM, Agent-Based Modeling (ABM) has emerged as a primary method of modeling these systems. In this investigation, we conduct a sensitivity analysis and thorough evaluation of an existing ABM of community forest management. We then modify the original model by providing a new enforcement mechanism that improves the validity of both …
Effects Of Thinning And Prescribed Burning On Tree Resistance To Extreme Drought In A Sierra Nevada Mixed-Conifer Forest, California Usa, Chance C. Callahan
Effects Of Thinning And Prescribed Burning On Tree Resistance To Extreme Drought In A Sierra Nevada Mixed-Conifer Forest, California Usa, Chance C. Callahan
Cal Poly Humboldt theses and projects
Drought-induced tree mortality can drastically alter forest composition, structure, carbon dynamics, and ecosystem function. Increasingly, forest policy and management focuses on how to improve forest resistance and resilience to drought stress. This study used tree ring data at Teakettle Experimental Forest (TEF), a historically frequent fire mixed-conifer forest in the California Sierra Nevada, to quantify how prescribed fire and mechanical thinning conducted in 2001-2002 influenced stand and tree-level growth responses to the extreme California drought of 2012-2016. Overstory thinning and understory thinning significantly enhanced growth responses to treatments alone and treatments during the drought at the stand-level. In each year …

The Impact Of Dutch Disease: The Case Of Nigeria, Halimat Atinuke Laguda
Masters Theses
Nigeria, over the years, has been showing a rapid appreciation of the domestic currency, a rise in real wages and the service sector and a slow-down in the industrial production which are all signs of presence of Dutch disease which predicts that a country with large natural resource rents may experience a de-industrialization and a lower long term economic growth. This paper analyses the impact of Dutch disease in Nigeria Ordinary Least square method, Two-Stage Least Square and Autoregressive Distributed Lag with a system of equation from 1981 to 2017 and found that the real wage rate emphasizes on the …
Northern San Francisco Bay Ecological Risk Assessment: Potential Crude By Rail Incident, Meagan Bowis
Northern San Francisco Bay Ecological Risk Assessment: Potential Crude By Rail Incident, Meagan Bowis
Master's Projects and Capstones
Oil spill models, ecological risks, response options, and costs were assessed for a discharge of Bakken crude oil into the Northern San Francisco Bay from a train derailment. This assessment was based on the risk of crude by rail derailments into the San Francisco Bay; in 2014, California oil refineries imported over 240 million gallons of Bakken crude oil by rail for processing. A hypothetical scenario was developed from a derailment on the Union Pacific Railroad Bridge and discharging 100,000 gallons of Bakken crude oil into the Northern San Francisco Bay. The oil trajectory impacted the Carquinez Strait, Suisun, San …
Soil Water Flux Estimates From Streaming Potential And Penta-Needle Heat Pulse Probe Measurements, Pawel J. Szafruga
Soil Water Flux Estimates From Streaming Potential And Penta-Needle Heat Pulse Probe Measurements, Pawel J. Szafruga
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Growing populations, coupled with climate change and resource depletion, have heightened concern about water management. The growing need to better manage agricultural systems, including irrigation and fertilizer application, as well the lasting consequences of excess application of nitrogen and other nutrients, could be remedied with an improved method to monitor soil water movement. Despite huge technological advances, a tool to measure soil water flow at the low rates found in the field has not been developed. Current methods lack the precision to provide the needed accuracy to fully understand soil-water dynamics, as well as the ability to provide instantaneous information. …
Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce
Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce
Electronic Theses and Dissertations
Common pool resource management systems are complex to manage due to the absence of a clear understanding of the effects of users’ behavioral characteristics. Non-cooperative decision making based on individual rationality (as opposed to group rationality) and a tendency to free ride due to lack of trust and information about other users’ behavior creates externalities and can lead to tragedy of the commons without intervention by a regulator. Nevertheless, even regulatory institutions often fail to sustain natural common pool resources in the absence of clear understanding of the responses of multiple heterogeneous decision makers to different regulation schemes. While modeling …
Turning Water Into Wine: The Political Economy Of The Environment In Southern California's Wine Country, Jason Simms
Turning Water Into Wine: The Political Economy Of The Environment In Southern California's Wine Country, Jason Simms
USF Tampa Graduate Theses and Dissertations
This dissertation examines questions of water sustainability in contexts of wine production and state-led neoliberal development in the Temecula Valley, southern California, where wine tourism is at present being harnessed as an engine of economic growth. Natural and anthropogenic forces, such as global climate change, desertification, urban development, and the marketization and commodification of natural resources, affect the distribution and availability of water throughout the globe. As a result, the use of water, and associated political and environmental processes and consequences, in the production of global commodities, including wheat, citrus, and coffee, recently have come under increased scrutiny. Given wine's …
The Politics Of Rsfs: An Antidote To Reversing The Resource Curse In Latin America?, Sarah Gagnon
The Politics Of Rsfs: An Antidote To Reversing The Resource Curse In Latin America?, Sarah Gagnon
Honors Theses
Over the past three decades, the world has become highly globalized. As such, most countries around the world depend on exports for a large portion of their national income. However, some countries’ dependency on exports is extreme, especially those that heavily rely on natural resource commodities. Despite the natural resource wealth that these commodities grant countries, due to the instability of global prices and the intensive focus of the resource extraction industry, scholars have theorized this type of dependency as a “resource curse.” The resource curse is a paradox where countries that are so rich in natural resources have not …
Tackling Tax Evasion: Transfer Price Manipulation, Extractive Natural Resources And A Strategy For The Southern African Customs Union, Patrick Grant Mclennan
Tackling Tax Evasion: Transfer Price Manipulation, Extractive Natural Resources And A Strategy For The Southern African Customs Union, Patrick Grant Mclennan
Electronic Theses and Dissertations
An increase in the number of multinational enterprises (MNEs) has increased the attention on cross-border challenges, such as transfer price manipulation (TPM). TPM is a development issue - it undermines institutions as well as siphons money from government revenues that could be directed towards programs for human development. Pervasive corruption in the natural resource sector supports an environment where TPM can flourish. This paper develops a strategy for combating TPM within the countries of the Southern African Customs Union. It does this by 1) defining the terrain of illicit flows, both generally and specifically to the abuse of transfer pricing …
Developing Tools To Identify Factors That Limit Production In Coastal Marshes, Vanessa Danielle Tobias
Developing Tools To Identify Factors That Limit Production In Coastal Marshes, Vanessa Danielle Tobias
LSU Doctoral Dissertations
Marsh loss is a problem in many areas around the world. In Louisiana’s coastal marshes, where Spartina patens is the most common plant, restoration and management seek to slow wetland loss rates that average approximately 77.4 km2/year. To combat the problem, scientists and managers require tools to determine local causes and evaluate the effectiveness of management techniques. Current methods for identifying factors that limit productivity in marshes are too time-consuming or expensive for wide-spread, regular use. Critical values of elemental concentrations in plant tissue are widely used to diagnose mineral deficiencies and toxicities in agricultural crops, however. I used the …

Environmental Kuznets Curve: Some Econometric Analyses., Soumyananda Dinda Dr.
Doctoral Theses
This dissertation explores some issues of environmental economics and development. A concept crystallizing in the development and environmental economics literature is the notion that socioeconomic and environmental measures follow predictable paths associated with growing per capita income. In this context, the nature of relationship between economic development and environmental quality has become the focus of increasing attention. The issue of whether environmental degradation increases monotonically, decreases monotonically, or at first increases and then declines along a country’s development path, has critical implications for policy. Whilst development through industrialization brings higher incomes and well-being, this seems to act as a magnifier …

Theoretical Issues In The Economics Of International Trade And Environment., Meeta Keswani Mehra Dr.
Doctoral Theses
In the wake of substantial trade liberalization in the world economy over the last two decades and growing environmental consciousness, the issues of the impacts of international goods trade and foreign direct investment (FDI) on local and global environment are becoming increasingly contentious. Whilst trade and FDI have been said to bring higher incomes and well-being for all, these are seen to act as "magnifiers" of environmental deterioration - especially in the developing countries. On the other hand, growing environmentalism is perceived to act as an impediment to freer trade and investment flows across countries. Hence, the central issues are …

High-Grade Paper Recycling: A Program Management Perspective, Rodger L. Carter
Theses and Dissertations
Recycling of high-grade paper is one method of reducing the use of natural resources and the amount of waste being emitted into the environment, both in the process of manufacturing and in the disposal of unneeded documents. The Air Force Materiel Command (AFMC) is a significant user of high-grade paper, thus recycling represents a potential saving to society in the form of lessened negative impact on the environment as the result of AFMC operations. The possibility also exists for AFMC to reduce operating costs. The purpose of this study is to explore means of reducing high-grade paper disposal by AFMC, …
Disparities In Development: A Case Study Of Karnataka State (India)., Jayalaxmi Jayaram Dr.
Disparities In Development: A Case Study Of Karnataka State (India)., Jayalaxmi Jayaram Dr.
Doctoral Theses
The Five Year Plans have recognised the need to bridge the developmental disparities across the regions and have formulated strategies for accelerated development of backward are as. However, the widening disparities between a few highly developed centres and vast areas of under development only bring out the inadequacies of the plans which are yet to integrate the resources of a region to its people. This study is an attempt to understand the spatial processes and patterns of development which offer an explanation to the intra/inter-regional contrasts in development. The study while high-lighting the importance of the Spatial approach has, in …
