Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs Oct 2018

Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs

Honors Theses, University of Nebraska-Lincoln

This appraisal attempts to remove subjectivity from the appraisal process and replace it with quantitative analysis of known data to generate a fair market value of the subject property. Two methods of appraisal were used, the income approach and the comparable sales approach. For the income approach, I used the average cash rent for the region, the current property taxes for the subject property, and a capitalization rate based on Stokes' (2018) capitalization rate formula to arrive at my income-based valuation. For the comparable sales approach, I utilized Stokes' (2018) research in optimization modeling to estimate a market value for ...

Agronomy Publications

Switchgrass (Panicum virgatum L.) has been the principal perennial herbaceous crop investigated for bioenergy production in North America given its high production potential, relatively low input requirements, and potential suitability for use on marginal lands. Few large trials have determined switchgrass yields at field scale on marginal lands, including analysis of production costs. Thus, a field-scale study was conducted to develop realistic yield and cost estimates for diverse regions of the USA. Objectives included measuring switchgrass response to fertility treatments (0, 56, and 112 kg N ha−1) and generating corresponding estimates of production costs for sites with diverse soil ...

Building From The Hiv Response Toward Universal Health Coverage, Jonathon Jay, Kent Buse, Marielle Hart, Robert Marten, Scott Kellerman, Morolake Odetoyinbo, Jonathan D. Quick, Timothy Evans, Peter Piot, Mark Dybul, Agnes Binagwaho

Open Dartmouth: Faculty Open Access Articles

Universal health coverage (UHC) has gained prominence as a global health priority. The UHC movement aims to increase access to quality, needed health services while reducing financial hardship from health spending, particularly in low- and middle- income countries.
As a policy agenda, UHC has been identified primarily with prepayment and risk-pool- ing programs. While financing policies provide important benefits, increasing access to health services will require broader reforms.
For lessons, the UHC movement should look to the global HIV response, which has confronted many of the same barriers to access in weak health systems. Considerable success on HIV has resulted ...

Transforming Ecosystems: When, Where, And How To Restore Contaminated Sites, Jason R. Rohr, Aïda M. Farag, Marc W. Cadotte, William H. Clements, James R. Smith, Cheryl P. Ulrich, Richard Woods Apr 2016

Transforming Ecosystems: When, Where, And How To Restore Contaminated Sites, Jason R. Rohr, Aïda M. Farag, Marc W. Cadotte, William H. Clements, James R. Smith, Cheryl P. Ulrich, Richard Woods

Integrative Biology Faculty and Staff Publications

Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. This has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require it. Nevertheless, ecological restoration remains a young and rapidly growing discipline and its intersection with toxicology is even more nascent and underdeveloped. Consequently, we provide guidance to scientists and practitioners on when, where, and how to restore contaminated ecosystems. Although restoration has many benefits, it also can be expensive, and in many cases systems can recover without human intervention. Hence, the first question we address is: "When ...

USDA National Wildlife Research Center - Staff Publications

The economics of managing disease transmission at the wildlife–livestock interface have received heightened attention as agricultural and natural resource agencies struggle to tackle growing risks to animal health. In the fiscal landscape of increased scrutiny and shrinking budgets, resource managers seek to maximize the benefits and minimize the costs of disease mitigation efforts. To address this issue, a benefit-cost analysis decision framework was developed to help users make informed choices about whether and how to target disease management efforts in wildlife and livestock populations. Within the context of this framework, we examined the conclusions of a benefit-cost analysis conducted ...

Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores Jul 2014

Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores

Honors College Theses

The human has caused a far greater impact on the planet's biodiversity than any other species in existence, due to the impact of population, afflluence, and technology. This thesis will argue the importance of biological diversity and how affluent populations are reducing biodiversity through the consumption of meat, electronics, and motor vehicles. Aldo Leopold's "The Land Ethic" and Herman Daly's "The Impossibility Theorem", among others, create a rubric evaluating human activities and provide alternative views on economic impossibilities. Consumption is reviewed from an ecocentric perspective, a holistic outlook placing emphasis on the ecosystem. The reader will become ...

Rabies transmitted by the common vampire bat is a major public health concern in subtropical and tropical areas of Latin America, and there is some concern that the species will eventually spread into south Texas. The objective of this study was to estimate the total economic impact of the potential spread of vampire bats into south Texas. Data on livestock populations and values in the relevant counties was combined with expected mortality rates to calculate livestock losses. An IMPLAN model of the regional economy was then used to estimate the secondary impacts experienced by other businesses in the region. These ...


Estimating The Total Economic Impact Of Black Bear Peeling In Western Oregon Using Gis And Remi, Jimmy D. Taylor Ii, Anita Morzillo, Aaron M. Anderson Jan 2014

Estimating The Total Economic Impact Of Black Bear Peeling In Western Oregon Using Gis And Remi, Jimmy D. Taylor Ii, Anita Morzillo, Aaron M. Anderson

USDA National Wildlife Research Center - Staff Publications

In parts of the Pacific Northwest, black bears emerge from winter dens with depleted fat reserves and feed on mature conifers by stripping bark and consuming sugar-rich sapwood. Peeling by bears affects commercial conifers through direct loss of the tree or degraded log quality at stand harvest. Bears generally peel trees from 15-30 years old in intensively managed forests until preferred foods such as fruits and berries are available, and a single bear can peel several trees per day. Dying trees have a signature red canopy and are detected in annual aerial forest health surveys; however, trees that scar over ...

Natural Resource Ecology and Management Publications

While grain crops are meeting much of the initial need for biofuels in the US, cellulosic or second generation (2G) materials are mandated to provide a growing portion of biofuel feedstocks. We sought to inform development of a 2G crop portfolio by assessing the profitability of novel cropping systems that potentially mitigate the negative effects of grain-based biofuel crops on food supply and environmental quality. We analyzed farm-gate costs and returns of five systems from an ongoing experiment in central Iowa, USA. The continuous corn cropping system was most profitable under current market conditions, followed by a corn–soybean rotation ...

Techno-Economic Modeling Of A Degummed Soybean Oil Biorefinery In 2005 & 2012, Bailley A. Richardson, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

As the biofuels industry expands, it is important to identify and quantize potential capital, operational, material, and utility costs, as well as possible sales prices for the biofuels and coproducts. Many industries use computer simulation programs for this function, as well as to see how using different operations can affect the overall production at the plant. The objective of this project was to determine how various operation scenarios affected capital, operational, material, and utility costs of a biodiesel biorefinery. These costs were examined using a techno-economic modeling program for a degummed soybean oil plant. It was clear after seeing economic ...


Techno-Economic Modeling Of Coproduct Processing In A Corn Based Ethanol Plant In 2012, Christine Wood, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan Jul 2013

Techno-Economic Modeling Of Coproduct Processing In A Corn Based Ethanol Plant In 2012, Christine Wood, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Coproducts, such as Distillers Dried Grains with Solubles (DDGS), produced during ethanol production are essential to the economic sustainability of each ethanol plant as they provide an additional source of revenue. DDGS is extensively used as animal feed, but has a relatively low market value compared to the biofuel. By fractioning DDGS into lighter and heavier fractions, the overall composition changes potentially increasing the value of the coproducts as they become more desirable to different markets. Earlier studies have examined fractionating DDGS using sieves and aspirators. This project examined the techno-economics of adding fractionation systems onto an existing 40 million ...

Delayed Planting, Prevented Planting And Replanting Crop Insurance Coverage, Steven D. Johnson, William M. Edwards May 2013

Delayed Planting, Prevented Planting And Replanting Crop Insurance Coverage, Steven D. Johnson, William M. Edwards

Integrated Crop Management News

The frequent rains that have soaked Iowa this year have left many corn and soybean fields unplanted or with flooded areas. Many producers are wondering what options they have under their multiple peril crop insurance (MPCI) policies.

In Iowa, the crop insurance “late planting period” for corn begins on June 1. Corn can still be planted after this date, but the insurance guarantee on those acres is reduced by 1 percent per day until the acres are planted. Corn acres planted after June 25 will receive insurance coverage equal to 60 percent of their original guarantee. Producers should keep accurate ...
