Development Of A Framework To Support Community-Scale Nutrient Recovery For Local Crop Fertilization And Production, Scott A. Lopez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nutrient and resource recovery (NRR) has become increasingly crucial as regions face deteriorating sanitation infrastructures, limited support, and growing environmental challenges. Implementing region-specific NRR technologies and systems could provide effective circular economy insights into addressing these challenges. Because of the multidisciplinary challenges associated with the design and implementation of NRR strategies, various government and local decision-makers need to collaborate effectively in the decision-making process. Structured decision-making (SDM) methodologies are practical when determining the most appropriate NRR strategy for nutrient-rich waste streams. However, applications of computational SDM limited because of the vast amounts of data that are needed to analyze the …

Pollution Emissions And Economic Growth In Asia Through The Lens Of The Environmental Kuznets Curve, Brian Jason H. Ponce, Yolanda T. Garcia, Gideon P. Carnaje, Agham C. Cuevas

Journal of Economics, Management and Agricultural Development

The nonlinear relationship of pollution emissions with economic growth alongside energy consumption variables was examined to test the Environmental Kuznets Curve (EKC) hypothesis using a panel sample comprising 34 Asian economies from 2001 to 2013. Panel Autoregressive Distributed Lag models in the forms of Pooled Mean Group and Mean Group models were estimated and tested against one another using the Hausman test. For robustness checks, the same econometric techniques were applied to disaggregated panel groups based on income classifications. The study reveals that, while the EKC hypothesis holds in Asia, the findings were not robust across the disaggregated panel groups. …

Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on the carbon balance of tundra ecosystems. In this study, we address some of these uncertainties through a novel record of 119 site-years of summer data from eddy covariance towers representing dominant tundra vegetation types located on continuous permafrost in the Arctic. Here we found that earlier snowmelt was associated with more tundra net CO2 sequestration and higher gross primary productivity (GPP) only in June …

Natural Resource System Size Can Be Used For Managing Recreational Use, Derek S. Kane, Kevin L. Pope, Keith D. Koupal, Mark A. Pegg, Christopher J. Chizinski, Mark A. Kaemingk

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Outdoor recreation provides societal benefits that are often measured by the amount of use natural resource systems receive. Still, the amount of resource use natural resource systems receive is often unknown or unstudied. Monitoring and quantifying resource use is often logistically difficult and costly but is paramount to optimize societal benefits. Identifying a simple and readily available metric that can indicate the quantity of recreational use of natural resource systems would benefit natural resource management. Using recreational angler participation data during an 11-year study period from 73 public waterbodies in Nebraska, USA, we developed a resource size-use model that demonstrates …

Mechanical and Aerospace Engineering Working Papers

Despite the climate commitments made by countries in the Paris Climate Agreement adopted in 2015, and reinforced during COP 21, world carbon emissions have increased in both 2021 and 2022. It is increasingly unlikely that the world can achieve the targeted 50% carbon reduction by 2030; the reduction approximately needed for reducing global temperature rise since the beginning of the industrial revolution to less than 1.5 deg. C. At the same time, the carbon intensive loads associated with bitcoin mining have grown, thereby contributing to growing worldwide carbon emissions. In this context, the role of cryptocurrency and particularly bitcoin is …

Development Of A Modified Screen Printed Electrode For The Determination Of Heavy Metals In Water Before And After Remediation With Food Grade Pectin And Citrofortunella Microcarpa Rinds, Shirley Palisoc, Natividad Michelle, Marissa Noel

Angelo King Institute for Economic and Business Studies (AKI)

The rapid increase in population, urbanization, and industrialization, along with inadequate water quality monitoring and wastewater management, contribute heavily to the pollution of water resources. Among the water contaminants of major concern, heavy metals are particularly considered as the most worrisome. Heavy metals tend to accumulate in the tissues of aquatic organisms (Ahmed et al., 2019; Rajeshkumar & Li, 2018; Tabrez et al., 2021) and thus increase in concentration upon moving higher up the food chain. This indicates that once humans ingest these organisms, they have a high risk of experiencing health problems as heavy metals are absorbed into their …

Intensifying permafrost thaw alters carbon cycling by mobilizing large amounts of terrestrial substrate into aquatic ecosystems. Yet, few studies have measured aquatic carbon fluxes and constrained drivers of ecosystem carbon balance across heterogeneous Arctic landscapes. Here, we characterized hydrochemical and landscape controls on fluvial carbon cycling, quantified fluvial carbon fluxes, and estimated fluvial contributions to ecosystem carbon balance across 33 watersheds in four ecoregions in the continuous permafrost zone of the western Canadian Arctic: unglaciated uplands, ice-rich moraine, and organic-rich lowlands and till plains. Major ions, stable isotopes, and carbon speciation and fluxes revealed patterns in carbon cycling across ecoregions …

Yankees In The Indian Ocean : American Commerce And Whaling, 1786–1860, Jane Hooper

Ohio University Press Open Access Books

The history of US imperialism remains incomplete without this consideration of long-overlooked nineteenth-century American commercial and whaling ventures in the Indian Ocean.

Yankees in the Indian Ocean shows how nineteenth-century American merchant and whaler activity in the Indian Ocean shaped the imperial future of the United States, influenced the region’s commerce, encouraged illegal slaving, and contributed to environmental degradation. For a brief time, Americans outnumbered other Western visitors to Mauritius, Madagascar, Zanzibar, and the East African littoral. In a relentless search for commodities and provisions, American whaleships landed at islands throughout the ocean and stripped them of resources. Yet Americans …

Low Levels Of Hybridization Between Sympatric Cold-Water-Adapted Arctic Cod And Polar Cod In The Beaufort Sea Confirm Genetic Distinctiveness, Robert E. Wilson, Sarah A. Sonsthagen, Philip Lavretsky, Andrew Majewski, Einar Árnason, Katrín Halldórsdóttir, Axel W. Einarsson, Kate Wedemeyer, Sandra L. Talbot

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

As marine ecosystems respond to climate change and other stressors, it is necessary to evaluate current and past hybridization events to gain insight on the outcomes and drivers of such events. Ancestral introgression within the gadids has been suggested to allow cod to inhabit a variety of habitats. Little attention has been given to contemporary hybridization, especially within cold-water-adapted cod (Boreogadus saida Lepechin, 1774 and Arctogadus glacialis Peters, 1872). We used whole-genome, restriction-site associated, and mitochondrial sequence data to explore the degree and direction of hybridization between these species where previous hybridization had not been reported. Although nearly identical …

Causal Forest Approach For Site-Specific Input Management Via On-Farm Precision Experimentation, Shunkei Kakimoto

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Estimating site-specific crop yield response to changes to input (e.g., seed, fertilizer) management is a critical step in making economically optimal site-specific input management recommendations. Past studies have attempted to estimate yield response functions using various Machine Learning (ML) methods, including the Random Forest (RF), Boosted Random Forest (BRF), and Convolutional Neural Network (CNN) methods. This study proposes use of the Causal Forest (CF) model, which is one of the emerging ML methods that comprise “Causal Machine Learning.” Unlike previous yield-prediction-oriented ML methods, CF focuses strictly on estimating heterogeneous treatment effects (changes in yields that result from changes in input …

The Ddt-Induced Decline Influenced Genetic Diversity In Naturally Recovered Peregrine Falcons (Falco Peregrinus) Nesting Within The Alaska Arctic And Eastern Interior, Sarah A. Sonsthagen,, Ted Swem, Skip Ambrose, Melanie J. Flamme, Clayton M. White, George K. Sage, Sandra L. Talbot

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We assessed the influence of the severe mid-20th century population decline on genetic diversity in nonaugmented Peregrine Falcon Falco peregrinus populations nesting within the Alaska Arctic and eastern Interior. Microsatellite and mitochondrial DNA (mtDNA) data were analysed for Peregrine Falcons sampled from three periods: pre-decline, decline and post-decline. The influence of the decline on genetic diversity differed between the two locales. The Alaska Arctic was characterized by shifts in mtDNA haplotype frequencies, increased inbreeding coefficient, reduction in effective population size and increase in private haplotypes, and a signature of post-decline population growth was detected; by contrast, the eastern Interior showed …

Blue Resilience: Is There A Need For An Alaskan Coastal Career Development Framework?, Jared Fuller

All Theses And Dissertations

Youth career outmigration has increased in Alaska’s coastal communities in the last few decades. The ocean and ocean-adjacent industries that comprise the blue economy make up the majority of the employment options in places have experienced declines within these regions which has been attributed to the outward movement of young people. The dynamic history of Alaska has had specific impacts with regards to Alaskan coastal communities, their ocean-resource economies, and thus, the potential for young people to find career paths within them. Potential economic-resource vulnerabilities could be mapped along with the complex systems to help build resilience within those communities. …

Valuing Angling On Reservoirs Using Benefit Transfer, Richard T. Melstrom, Mark A. Kaemingk, Nicholas W. Cole, John C. Whitehead, Christopher J. Chizinski, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two …

Vermont Global Warming Solutions Act: The Costs Of Inaction From Land Conversions, Grayson L. Younts

All Theses

The Vermont (VT) Global Warming Solutions Act (GWSA, 2020) sets greenhouse gas (GHG) emissions reduction targets as 26% below 2005 by 2025, 40% below 1990 by 2030 and 80% below 1990 by 2050 for energy-related emissions only. Vermont’s omission of GHG emissions from land conversions can result in significant costs of inaction (COI), which can hinder state’s mitigation and adaptation plans and result in a climate crisis-related risks (e.g., credit downgrade). Science-based spatio-temporal data of GHG emissions from soils as a result of land conversions can be integrated into the conceptual framework of “action” versus “inaction” to prevent GHG emissions. …
