Executive Summary
The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and …
Moving From Final To Useful Stage In Energy-Economy Analysis A Critical Assessment, Matthew K. Heun
Moving From Final To Useful Stage In Energy-Economy Analysis A Critical Assessment, Matthew K. Heun
University Faculty Publications and Creative Works
Given the climate change emergency, reducing energy consumption, which is responsible for most greenhouse gases emissions worldwide, is a priority. However, the strong historical link between energy consumption and economic growth questions whether continued economic growth is compatible with energy conservation targets. Conventional final energy analysis (common analysis methods applied at the final energy stage) has provided limited insights to this nexus. In response, this paper explores the extent to which useful stage analysis provides additional insights using three common methods: aggregate energy-economy analysis (growth rates, energy intensities, and Index Decomposition Analysis), energy-GDP causality testing, and Aggregate Production Function modelling, …
A Systematic Review Of The Use Of Environmental Economics In The Mining Industry, Maria Menegaki, Dimitris Damigos
A Systematic Review Of The Use Of Environmental Economics In The Mining Industry, Maria Menegaki, Dimitris Damigos
Journal of Sustainable Mining
Environmental economics is increasingly being used in project appraisals, environmental liability estimates and design of market-based instruments. Mining, an actor capable of causing adverse effects on the environment, human health and well-being, has already been affected by these developments, at a great extent. Up to date, several research studies have been carried out to monetise the externalities of mining projects. Nevertheless, a systematic review of these publications has not been carried out, yet. This paper aims to fill this gap in the literature by investigating (i) the main non-market valuation techniques used; (ii) the main external costs or benefits of …

Moving Beyond ‘More Crop Per Drop’: Insights From Two Decades Of Research On Agricultural Water Productivity, Meredith Giordano, Susanne M. Scheierling, David O. Tréguer, Hugh Turral, Peter G. Mccornick
Moving Beyond ‘More Crop Per Drop’: Insights From Two Decades Of Research On Agricultural Water Productivity, Meredith Giordano, Susanne M. Scheierling, David O. Tréguer, Hugh Turral, Peter G. Mccornick
Daugherty Water for Food Global Institute: Faculty Publications
Concern over increasing water scarcity has led to the introduction of the concept of agricultural water productivity and an emphasis on interventions to achieve ‘more crop per drop’. Yet, a strong debate continues on how the concept is to be defined and used. Drawing largely from the irrigation literature, the origins of the concept and its methodological developments are reviewed, and its use in applied work over two decades is discussed. Based on this analysis of conceptual and applied research, key insights into the concept’s contributions and limitations are presented, as well as opportunities for further refinements.

Technical Efficiency Of Milkfish Production In The Province Of Iloilo, Philippines, Lylve Maliz L. Zeller, Salvador P. Catelo, Nora Dm. Carambas
Journal of Economics, Management and Agricultural Development
The Philippine aquaculture sector is primarily dominated by milkfish, with the province of Iloilo as one of the key producing areas. However, the production in the province has exhibited a decreasing trend since 2011. In this light, this study is undertaken to determine the technical efficiency of milkfish production in the province of Iloilo and identify the factors that significantly affect such efficiency. Utilizing the maximum likelihood estimation method, a Cobb-Douglas production function was specified to estimate farm-level efficiency using the data from 181 milkfish producers interviewed. The technical efficiency scores ranged between 12.38% to 90.00%, with a mean of …
An Ardl Approach In Studying The Impact Of Asf And Selected Factors On The Philippine Pork Market Retail Price, Lara Paul A. Ebal
An Ardl Approach In Studying The Impact Of Asf And Selected Factors On The Philippine Pork Market Retail Price, Lara Paul A. Ebal
Journal of Economics, Management and Agricultural Development
This study aimed to explore the impact of the farmgate price of hogs, the volume of hog production, the volume of imported pork, the market retail price per kilo of dressed chicken, the quantity of pork consumed by the population, the GDP per capita, and African Swine Fever (ASF) on the pork market retail price in the Philippines. The Autoregressive Distributed Lag (ARDL) approach was implemented to model the pork price using quarterly data from 2000 to 2020. The long-run model showed that farmgate price, hog production, and imported pork during the presence of ASF could affect pork price. Moreover, …

Investigating The Intention To Work Overseas Among Filipino Engineering Students By Testing A Structural Equation Model Based On An Extended Theory Of Planned Behavior, John Lester Remot, Maria Liezel P. Caroche, Alan Marco S. Mercado, Marc Joseph S. Villanueva
Journal of Economics, Management and Agricultural Development
This study examined the antecedents of Filipino engineering students’ intention to work overseas, applying the theory of planned behavior (TPB) (involving attitude, subjective norm, and perceived behavioral control) extended with migration push and pull factors (PPF) (involving salary and compensation, career prospects, and quality of life). Structural equation modeling using 1,706 questionnaire responses proved that the PPF dimensions were indistinguishable, while another factor distinct from attitude, evoking the perceived enjoyment of working overseas (PEJ), emerged. The TPB and PPF were identified as important antecedents of intention (R2 = 0.667). PEJ had no direct effect on it but was significant along …

We All Want To Change The World: How Behavioral Insights Can Help Reduce Carbon Emissions, Thomas C. Gifford
We All Want To Change The World: How Behavioral Insights Can Help Reduce Carbon Emissions, Thomas C. Gifford
Electronic Theses and Dissertations
The world is in the midst of an unprecedented environmental crisis driven primarily by human behavior. As the world has globalized, countries have developed, and standards of living have improved, global pollution has skyrocketed and has resulted in a wide range of environmentally destructive outcomes. All paths to environmentally sustainable development involve a dramatic cut in carbon emissions from current day levels. In this thesis, I explore how the omission of behavioral factors from mainstream neoclassical models has contributed to, and can aid in reducing unsustainably high levels of carbon emissions. Throughout the history of economic thought, classical economists such …
Evaluating Nuclear Energy As A Component Of U.S. Energy Innovation Systems, Bryce Jones
Evaluating Nuclear Energy As A Component Of U.S. Energy Innovation Systems, Bryce Jones
Electronic Theses and Dissertations
Nuclear energy is contentious in policy discussions that evaluate its role in the current U.S. clean energy innovation system. OECD nations, on average, have begun to reduce their dependence on nuclear energy. However, the United States has remained invested in its nuclear energy infrastructure and the role that it plays within federal research and development. This thesis examines the Neo-Schumpeterian perspective and the National Innovation System’s approach, the economic history of nuclear energy in the United States, and given insight from these factors, discusses the current role of nuclear energy in the U.S. energy innovation system. The objective is to …

Vegetation indices (VIs) data derived from satellite imageries play a vital role in land surface vegetation and dynamic monitoring. Due to the excessive noises (e.g., cloud cover, atmospheric contamination) in daily VI data, temporal compositing methods are commonly used to produce composite data to minimize the negative influence of noise over a given compositing time interval. However, VI time series with high temporal resolution were preferred by many applications such as vegetation phenology and land change detections. This study presents a novel strategy named DAVIR-MUTCOP (DAily Vegetation Index Reconstruction based on MUlti-Temporal COmposite Products) method for normalized difference vegetation index …

Temporal Invariance Of Social-Ecological Catchments, Mark A. Kaemingk, Christine N. Bender, Chris Chizinski, Aaron J. Bunch, Kevin L. Pope
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Natural resources such as waterbodies, public parks, and wildlife refuges attract people from varying distances on the landscape, creating “social-ecological catchments.” Catchments have provided great utility for understanding physical and social relationships within specific disciplines. Yet, catchments are rarely used across disciplines, such as its application to understand complex spatiotemporal dynamics between mobile human users and patchily distributed natural resources. We collected residence ZIP codes from 19,983 angler parties during 2014–2017 to construct seven angler–waterbody catchments in Nebraska, USA. We predicted that sizes of dense (10% utilization distribution) and dispersed (95% utilization distribution) angler–waterbody catchments would change across seasons and …

Bats are important bio-indicators of ecosystem health and provide a number of ecosystem services. White-nose Syndrome and habitat loss have led to the decline of many bat species in eastern North America, including the federally threatened northern long-eared bat, Myotis septentrionalis. White-nose Syndrome was only recently found in Nebraska, which lies on the western extent of this species geographic range. To better understand how this forest-dependent species persists in an agriculturally dominated landscape amid a growing number of pressures, we investigated the roosting habits of this bat at the Homestead National Monument of America, located in southeast Nebraska. We …

Phylogenomics Reveals Ancient And Contemporary Gene Flow Contributing To The Evolutionary History Of Sea Ducks (Tribe Mergini), Philip Lavretsky, Robert E. Wilson, Sandra L. Talbot, Sarah A. Sonsthagen
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Insight into complex evolutionary histories continues to build through broad comparative phylogenomic and population genomic studies. In particular, there is a need to understand the extent and scale that gene flow contributes to standing genomic diversity and the role introgression has played in evolutionary processes such as hybrid speciation. Here, we investigate the evolutionary history of the Mergini tribe (sea ducks) by coupling multi-species comparisons with phylogenomic analyses of thousands of nuclear ddRAD-seq loci, including Z-sex chromosome and autosomal linked loci, and the mitogenome assayed across all extant sea duck species in North America. All sea duck species are strongly …

Political attacks against scientists and scientific research are nothing new, though the Trump Administration appears to have increased both the breadth and the depth of such attacks. What is new, it seems, are attacks on science that are not in service of protecting any identifiable regulated industry. Under the Trump Administration, the attacks on science are more systemic, and aimed more at reducing scientific capacity in the federal government, rather than mere one-off policy interventions to help an individual industry.
This Article suggests that the Trump Administration, more than previous administrations, has sought to use science as part of a …
Exploring The Determinants Of Aspects Of Rotational Grazing In The U.S. Great Plains, Iftekhar Uddin Ahmed Chowdhury
Exploring The Determinants Of Aspects Of Rotational Grazing In The U.S. Great Plains, Iftekhar Uddin Ahmed Chowdhury
Electronic Theses and Dissertations
Pasture and rangeland make up about 45 percent of the agricultural land in the U.S. Great Plains and one of the most common form of mismanagement of this pasture is overgrazing. Which results in many detrimental effects on environment. Many practitioners endorsed Rotational grazing (RG) as an improved grazing management practice over season-long continuous grazing. The overall goal of the current study is to assess the certain aspects of using RG in the U.S. Great Plains. Using mail survey data of the of 874 beef cattle producers of North Dakota, South Dakota, and Texas, the study found that neighborhood practice, …

A Hand-Held Structure From Motion Photogrammetric Approach To Riparian And Stream Asseessment And Monitoring, Joseph M. Dehnert, Joseph Dehnert
Graduate Student Theses, Dissertations, & Professional Papers
Two of the biggest weaknesses in stream restoration and monitoring are: 1) subjective estimation and subsequent comparison of changes in channel form, vegetative cover, and in-stream habitat; and 2) the high costs in terms of financing, human resources, and time necessary to make these estimates. Remote sensing can be used to remedy these weaknesses and save organizations focused on restoration both money and time. However, implementing traditional remote sensing approaches via autonomous aerial systems or light detection and ranging systems is either prohibitively expensive or impossible along small streams with dense vegetation. Hand-held Structure from Motion Multi-view Stereo (SfM-MVS) photogrammetric …

Effective conservation for listed migratory species requires an understanding of how drivers of population decline vary spatially and temporally, as well as knowledge of range-wide connectivity between breeding and nonbreeding areas. Environmental conditions distant from breeding areas can have lasting effects on the demography of migratory species, yet these consequences are often the least understood. Our objectives were to 1) evaluate associations between survival and extreme environmental disturbances at nonbreeding areas, including hurricanes, harmful algal blooms, and oil spills, and 2) estimate migratory connectivity between breeding and nonbreeding areas of midcontinental piping plovers (Charadrius melodus). We used capture …
Analyzing The Potential Of Bioelectrical Impedance Analysis In Identifying The Effects Of Freezing In Atlantic Sea Scallop Products (Placopecten Magellanicus), Joseph Ehrhard
All Theses And Dissertations
The sensitivity of bioelectrical impedance analysis (BIA) was investigated to assess the potential of identifying the effects of freezing in market-ready Atlantic sea scallops (Placopecten magellanicus). Measurements of resistance (R) and reactance (Xc) were recorded using a Certified Quality Reader (CQR) (Certified Quality Food Inc., Clinton Township, MI 48035) BIA device at 50kHz. Prior to investigating the effects of freezing on BIA measurements a standard operating procedure (SOP) was established to limit sources of error. BIA measurements were used in establishing an SOP which focused upon the preparation of samples through blot drying, as well as, proper orientation …

Nanomaterials (NMs), both natural and synthetic, are produced, transformed, and exported into our environment daily. Natural NMs annual flux to the environment is around 97% of the total and is significantly higher than synthetic NMs. However, synthetic NMs are considered to have a detrimental effect on the environment. The extensive usage of synthetic NMs in different fields, including chemical, engineering, electronics, and medicine, makes them susceptible to be discharged into the atmosphere, various water sources, soil, and landfill waste. As ever-larger quantities of NMs end up in our environment and start interacting with the biota, it is crucial to understand …
