Opportunities For Nebraska In Future Carbon Markets: Final Technical Report For Ncesr Project 3-#303, Richard K. Perrin, Adam J. Liska, Lilyan E. Fulginiti

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

This study was funded to explore potential opportunities for Nebraska in future carbon markets, most explicitly those opportunities related to the possibility of replacing fossil fuels with biomass at Nebraska corn ethanol plants. The most direct and significant finding is that biomass-fired CHP (combined heat and power) technology is not economically viable for Nebraska corn ethanol plants under current conditions. We estimate in the study that corn stover price would have to be at least $50 per ton of dry matter for the requisite amounts to be delivered to any of the three ethanol plant locations considered (Adams, Norfolk and …

The 'Goldilocks Hypothesis' : A Political Ecology Of The Land-Sparing/Wildlife-Friendly Farming Debate, M. Jahi Chappell

Systems Science Friday Noon Seminar Series

Proposals for biodiversity conservation as related to the dominant form of human land use, agriculture, have broadly coalesced around two paradigms: "Land sparing" and "Wildlife-friendly farming." Neither paradigm is sufficiently grounded in the more complex socioeconomic realities of the food system with regards to another paramount problem of our time: widespread malnutrition. However, the "land sparing" paradigm's simplistic approach to food, policy, and ecosystem dynamics is arguably more egregiously out of sync with current knowledge. The talk will present a conceptual view of food systems, hunger, and biodiversity conservation, with the goal of generating discussion on how to systematically integrate …

Increasing Returns To Marketing In Zambian Maize Markets, Gelson Tembo, Thomas S. Jayne

Zambia Social Science Journal

The article investigates the existence of market externalities due to increasing returns to marketing. Panel data on 198 pairs of maize markets in Zambia and correlated random effects linear and tobit estimators were used to model the relationship between market externalities and producer-to-wholesale marketing margins. This article is one of the first to explicitly account for unobserved local market heterogeneity in a developing country context. The results suggest that Zambian smallholder maize markets are substantially specialized with significant margin-reducing own externality effects and insignificant cross-externality effects. The results also indicate that the unobserved market effects exert a systematic influence on …

An Analysis Of Supply Contracts In The Livestock Markets Of The United States, Doussou Traore

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

In this report, we discuss market relations in the cattle and beef sector of the United States by setting up a sequence of optimization decisions taken by cattle feeders (producers, sellers) and meat packers (processors, buyers) to solve for the equilibrium supply and demand proportions in the contract market in a first stage given the respective degrees of risk aversion for the representative producer and processor. Subsequently we derive the impacts of contracts, namely impacts on the spot market price and the processors’ ability to exercise oligopsony power, in a second stage. Using a model for a fixed-price contract, the …

Sorghum And Pearl Millet Improved Seed Value Chains In Zambia: Challenges And Opportunities For Smallholder Farmers, Priscilla Hamukwala, Gelson Tembo, Don Larson, Mark Erbaugh

INTSORMIL Scientific Publications

Sorghum and millet are a very important source of food and farm income for smallholder farmers, which can be enhanced especially if linked to new markets. These two crops have been widely viewed as minor traditional crops in the Zambian food systems. The two crops were displaced by maize in the 1900s with the opening of the copper mines. However, they remain important food crops for semi-arid areas of the country. In recent years, there have also been new market developments requiring farmers to increase productivity and production. Unfortunately significant productivity enhancements are impeded by low access to improved technologies …

Semillas Y La Ciudad: La Agricultura Urbana En Oaxaca De Juárez Como Un Aporte A La Soberanía Alimentaria, Katie Oberwager

Independent Study Project (ISP) Collection

Este proyecto trata de examinar el movimiento creciente de la agricultura urbana en Oaxaca de Juárez, México como un aporte potencial a la soberanía alimentaria. Las políticas económicas en los Estados Unidos tienen un efecto directo en las vidas mexicanas, y esto es especialmente la verdad con los campesinos mexicanos. Por ejemplo, el Tratado de Libre Comercio de América del Norte ha causado la inundación de México con maíz barato. La mayoría de los campesinos mexicanos no pueden competir con estos precios bajos y han sido obligados a huir de su tierra en busca de trabajo en las ciudades o …

The Prospects Of Using Athrospira Platensis As A Malnutrition Treatment In Kenya, Kari N. Harris

Independent Study Project (ISP) Collection

The purpose of this research was to explore the current efforts using spirulina as a malnutrition treatment in Kenya. There are currently five spirulina cultivation sites that growing spirulina, four of which are located in the Nyanza Province. Their production and scope of advocacy efforts are limited. Some of the cultivation sites have a better quality control measures and strategic plan in place for expanding cultivation. Significant efforts need to be made to improve the scope of production and create links with nutrition experts in other non-governmental organizations and at the national level.

Foodshed Foundations: Law's Role In Shaping Our Food System's Future, Margaret Sova Mccabe

Law Faculty Scholarship

[. . .] This symposium Article analyzes how we can rethink the architecture of law based on a foodshed model to provide a greater role for local, state, and regional government in the American food system. In turn, greater roles for different levels of government may help America achieve greater efficiencies in domestic food safety, nutrition and related public health issues, sustainability, and international trade.

Americans need a greater voice in the food system. The foodshed model is a powerful vehicle that allows us to conceptualize change, allowing greater citizen participation and a more nuanced approach to food policy. The …

Guano Exploitation In Madagascar, Christina Buliga

Independent Study Project (ISP) Collection

Agriculture in Madagascar continues to remain largely undeveloped. Out of the eighty percent of Malagasy individuals that live in rural areas an overwhelming sixty five percent practice subsistence agriculture. With respect to the country as a whole this means that out of Madagascar's 58.2 million hectares of available land only 5.2 percent (3 million hectares) are farmed. And out of these 3 million hectares only 67% are cultivated permanently and only 11% are fertilized.

While there are several reasons for why Madagascar’s agriculture has remained largely undeveloped and for why Madagascar continues to rely on imported crops to meet its …

Environmental Efficiency Among Corn Ethanol Plants, Juan P. Sesmero, Richard K. Perrin, Lilyan E. Fulginiti

Department of Agricultural Economics: Faculty Publications

Economic viability of the US corn ethanol industry depends on prices, technical and economic efficiency of plants and on continuation of policy support. Public policy support is tied to the environmental efficiency of plants measured as their impact on emissions of greenhouse gases. This study evaluates the environmental efficiency of seven recently constructed ethanol plants in the North Central region of the U.S., using nonparametric data envelopment analysis (DEA). The minimum level of GHG emissions (per gallon of ethanol produced) feasible with the available technology is calculated for each plant and this level is used to decompose environmental efficiency into …

Subcritical Contraction For Improved Open-Channel Flow Measurement Accuracy With An Upward-Looking Advm, Daniel Howes, Charles M. Burt, Brett F. Sanders

BioResource and Agricultural Engineering

Acoustic Doppler velocity meters (ADVMs) provide an alternative to more traditional flow measurement devices and procedures such as flumes, weirs, and stage rating for irrigation and drainage canals. However, the requirements for correct calibration are extensive and complex. A three-dimensional computational fluid dynamics (CFD) model was used to design a subcritical rapidly varied flow contraction that provides a consistent linear relationship between the upward-looking ADVM sample velocity and the cross-sectional average velocity in order to improve ADVM accuracy without the need for in situ calibration. CFD simulations validated the subcritical contraction in a rectangular and trapezoidal cross section by showing …

Getting Honest With Oil, Bruce B. Johnson

Cornhusker Economics

In this year of the monumental oil spill off our shores, Americans are being brought face-to-face with some stark realities of our time. First, we are seeing that current technology and human processes can’t insure the prevention of environmental disasters, creating havoc to large economic regions as well as to fragile ecosystems. In fact, if a single 21-inch pipe spewing millions of barrels of oil from the floor of the Gulf can continue for months on end, without effective correction, just how ingenious are we as humans?

Grid Pricing: An Empirical Investigation Of Market Signal Clarity, Scott Fausti, Bashir Qasmi, Jing Li

Economics Staff Paper Series (1969 - 2017)

The ability of the grid marketing system for fed cattle to provide an efficient price transmission mechanism is investigated. Nerlove' s (1958) adaptive expectations approach is adopted to model the relationship between grid premiums (discounts) and the weekly relative supply of carcass quality attributes. Linear regression techniques are used to estimate Nerlove's supply response function. Granger Causality tests are conducted to investigate the relationship between grid premiums (discounts) and the relative supply of carcass quality attributes. Regression estimates and the Granger Causality tests provide empirical support for the 2005 National Beef Quality Audit call for clearer market signals.
