Diving Into Food Justice: Food Waste In The Anthropocene, Kathleen P. Hunt, Abby Dubisar 2016 Iowa State University

Diving Into Food Justice: Food Waste In The Anthropocene, Kathleen P. Hunt, Abby Dubisar

Abby Dubisar

The Anthropocene calls for greater attention to the various and complicated ways by which humans interact with the environment and compels critical dialogue to identify and implement alternative solutions. With few exceptions, organisms (including human and more-than-human) require food as a biological need for survival. The global agrifood system has broad environmental consequences. For example, “getting food from the farm to our fork eats up 10 percent of the total U.S. energy budget, uses 50 percent of U.S. land, and swallows 80 percent of all freshwater consumed in the United States” (Gunders, 2012). Food ranks among the top ...

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford 2016 University of Montana, Missoula

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford

STAR (STEM Teacher and Researcher) Presentations

Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that ...

The Demand For Agricultural Research By State Governments, Jyoti Khanna, Wallace E. Huffman, Todd Sandler 2016 Iowa State University

The Demand For Agricultural Research By State Governments, Jyoti Khanna, Wallace E. Huffman, Todd Sandler

Wallace Huffman

Public agricultural research in 'the United States is conducted- by state agricultural experiment stations (SAES) and'by the' research agencies of the USDA.. Both have research.'activities 'in ;every state." A. vast^ amount "of research and experiments has shown that the'-performance of plants and to-a lesser extent animals', ' in which! new technologies are frequently-embodied,' is altered by ,local geoclimatic conditions-that; differ within' and between states. Basic research and livestock .research"^ to- some extent lead to new knowledge or technologies that spill widely across^ state boundaries^; '-Thus, public-^ agricultural-.research produces-knowledge .that/is both^ state specific' and general.


Setting Efficient Incentives For Agricultural Research: Lesson From Principal-Agent Theory Ii, Wallace E. Huffman, Richard E. Just 2016 Iowa State University

Setting Efficient Incentives For Agricultural Research: Lesson From Principal-Agent Theory Ii, Wallace E. Huffman, Richard E. Just

Wallace Huffman

At least since the 1950s, studies have shown unusually high productivity of public agricultural research (e.g., Griliches; Huffman and Evenson; Ruttan; Schultz). In response, many have asked why more funds are not allocated to public agricultural research. More recently, following the large budget deficits of the 1980s, funding conditions have tightened and forced both the research agencies of the U.S. Department of Agriculture and many of the state agricultural experiment stations (SAES) into a contracting mode. Under unprecedented budget pressures, administrators and public decision makers have struggled to set priorities to reduce budgets without significant loss of productivity ...


Measuring Public Agricultural Research And Extension And Estimating Their Impacts On Agricultural Productivity: New Insights From Us Evidence, Yu Jin, Wallace E. Huffman 2016 Iowa State University

Measuring Public Agricultural Research And Extension And Estimating Their Impacts On Agricultural Productivity: New Insights From Us Evidence, Yu Jin, Wallace E. Huffman

Wallace Huffman

In order to feed the growing population of the world, expected to reach 9.6 billion people—a 29 percent increase over 2013—by 2050 without causing immense environmental damage and hunger, society must increase agricultural productivity. Investing further in public agricultural research and extension will help alleviate this problem. Developed countries, like the United States, have been a leader in this area for most of the twentieth century. For example, US public agricultural research grew rapidly from 1960–1980, but slowed considerably from 1980–1995, showed negative growth from 1995–1998, then flattened by 2010.


Human Capital: Education And Agriculture, Wallace E. Huffman 2016 Iowa State University

Human Capital: Education And Agriculture, Wallace E. Huffman

Wallace Huffman

This chapter presents a review and synthesis of effects of education in agriculture, summarizes major contributions, and suggests major research gaps in the literature. Although growth in knowledge enables skill acquisition and specialization of labor, which generally raises labor productivity, and technical change, the dominant effect on agriculture has been technical change. A puzzle remains why schooling does not have broader direct impacts in agriculture. Furthermore, as we proxy education or general intellectual achievement by schooling in our empirical research, this has led to biased interpretations of impacts when general intellectual achievement of school graduate changes over time and perhaps ...


Convergence In U.S. Tfp Growth For Agriculture: Implications Of Interstate Research Spillovers For Funding Agricultural Research, Alan McCunn, Wallace E. Huffman 2016 Iowa State University

Convergence In U.S. Tfp Growth For Agriculture: Implications Of Interstate Research Spillovers For Funding Agricultural Research, Alan Mccunn, Wallace E. Huffman

Wallace Huffman

This paper examines state agricultural total factor productivity (TFP) data, 1950- 1982, for evidence of convergence, i.e., TFP growth rates of the future are inversely related to the TFP level at the starting data. After finding evidence of convergence, the paper examines the contributions of public and private R&D to convergence and presents implications for a more efficient organization of public agricultural research. For example, we &id that increasing a states own investment in public agricultural research reduces the rate of TFP convergence but larger public investments in surrounding areas that potentially spilling increase the rate of convergence ...


A Brief History Of Corn: Looking Back To Move Forward, Jon Derek Pruitt 2016 University of Nebraska-Lincoln

A Brief History Of Corn: Looking Back To Move Forward, Jon Derek Pruitt

Doctoral Documents from Doctor of Plant Health Program

Maize was domesticated from teosinte in Mexico some 7,000 to 10,000 years ago and quickly spread through the Americas. It has become one of the most important crops at a local and global level. Two types, Northern Flint corn and Southern Dent corns provided the basis of the genetic background of modern maize hybrids. The development of hybrids, first double-cross and later single-cross hybrids, along with a transition to high input farming provided huge yield increases, which have continued to improve with improving technology.

Increase in maize production also caused a rise in Western corn Rootworm (Diabrotica virgifera ...


Evaluation Of Fungicide Efficacy Against Cercospora Sojina And Selection For Qoi-Fungicide Resistance In Soybean, Alicia Mercedes Cochran 2016 University of Tennessee - Knoxville

Evaluation Of Fungicide Efficacy Against Cercospora Sojina And Selection For Qoi-Fungicide Resistance In Soybean, Alicia Mercedes Cochran

Masters Theses

Frogeye leaf spot (FLS) of soybean is caused by Cercospora sojina. In 2010, resistance to the quinone outside inhibitor (QoI) fungicides was reported. Since then, evaluating FLS for QoI-resistance has been of particular interest in Tennessee and other soybean-producing states. In order to determine alternative fungicide options, fungicides with solo and combination mode of action were tested in 2013-2014. The objectives were,1) to evaluate fungicide efficacy for disease control and yield protection, and 2) evaluate selection pressure for QoI-resistance. Treatments included the following fungicide groups: QoI, DMI, MBC, Chlorothalonil, QoI+DMI, SDHI+QoI, SDHI+QoI+DMI, and DMI+MBC ...


Improved Microplate Fluorometric Soil Enzyme Assay For Β-Glucosidase Detection, Emily C. Hoehn 2016 University of Nebraska-Lincoln

Improved Microplate Fluorometric Soil Enzyme Assay For Β-Glucosidase Detection, Emily C. Hoehn

Dissertations & Theses in Natural Resources

Soil microbes produce extracellular enzymes responsible for degrading complex organic compounds to release energy and nutrients. Measurement of soil enzymes can be considered an indicator of soil health and microbial community composition because of its sensitivity to agricultural and management practices. Fluorescence enzyme assays tend to be more sensitive than spectrophotometric (ie. colorimetric) assays and a 96-well plate has the potential capacity for high-throughput use. Development of a newly modified enzyme assay using fluorometric (4-methylumbelliferone), automated pipetting system and sonication, as well as a reduction in replicates allows for a higher sample throughput rate suitable for service laboratory use. The ...

Agricultural and Biosystems Engineering Publications

In 2007, a Virtual Education Center for Biorenewable Resources was initiated that offered three online courses, one being Biorenewable Resources and Tech¬nology (BRT) 501 – Fundamentals of BRT. The objective was to assess student perceptions on two delivery methods, course assessments, module material, and student learning. Twenty students completed the survey of qualitative aspects of student experiences in BRT 501. The biomass production module brought non-farm students closer to the knowledge level of farm students as demonstrated by students’ self-assessed knowl¬edge and their BRT 501 assessment scores. Students desired a stronger connection with the course instructor and peers, whether ...
