Cost-Benefit Analysis Of Farmer Training In Ghanaian Cocoa Farming, Michael Norton

Agricultural Economics and Agribusiness Undergraduate Honors Theses

While billions of dollars flow into low-income countries each year to help alleviate poverty, assessing the effectiveness of these dollars is a challenging task. The literature is rich in studies that measure the benefits of rural development programs. However, many of these studies lack a temporal dimension because they measure cost and benefits for only capital investments and for only a single, static year, while not accounting for skill enhancement. By only measuring net producer benefits during the life of the development program, the cost-benefit analyses (CBA) may not truly capture the full net benefits of a given program. In …

Effect Of Ph And Temperature On The Binding Interactions Of Caffeine And Chlorogenic Acid With Sodium Caseinate, Emily S. Kong

Master's Theses

Coffee is a popular and well-loved beverage consumed worldwide by millions of people every day. While most patrons of coffee do so because of its unique and satisfying taste, consumers may be unaware of the potential beneficial health effects it also imparts. The antioxidants found in green coffee beans collectively known as chlorogenic acids (CGA) and caffeine are two of the most abundant bioactive compounds present in coffee. Both these bioactive compounds have been implicated in many studies to impart a wide range of health benefits, from reducing the risk of Type 2 diabetes, to their use as aides in …

Using The Ceres-Maize Model To Create A Geographically Explicit Grid Based Estimate Of Corn Yield Under Climate Change Scenarios, Ryan Zachary Johnston

Graduate Theses and Dissertations

The CERES-Maize model was evaluated in its capacity to predict both regional maize yield and water use within the United States Department of Agriculture (USDA) Economic Research Service (ERS) Region 1 between the years 1997-2007. A grid based, geospatially explicit method was developed to express the various rainfed and irrigated maize cultivars grown across the region. Overall, the calibrated model compared well for both physiological and yield parameters, producing significant linear relationships (p

The calibrated and validated CERES-Maize model was used to predict potential evapotranspiration and yield under three IPCC weather scenarios for the year 2050 to evaluate crop production …

The Impact Of The U.S. Sugar Program Redux, John C. Beghin, Amani Elobeid

Department of Agricultural Economics: Faculty Publications

We analyze the various welfare costs, transfers, trade, and employment consequences of the current U.S. sugar program for U.S. consumers, other sugar users, sugar refiners, cane and beet growing and processing industries, other associated agricultural sectors, and world markets. The removal of the sugar program would increase U.S. consumers’ welfare by $2.9 billion to $3.5 billion each year and generate a modest job creation of 17,000 to 20,000 new jobs in food manufacturing and related industries. Imports of sugar containing products would fall dramatically, especially confectioneries substituting for domestic inputs under the sugar program. Sugar imports would rise substantially to …

Dogs, Pine Trees, And Carbs, Neil P.J. Price, Marcia Wood

Agricultural Research Magazine

Carbohydrates from a perhaps surprising source—pine trees—may have beneficial effects on dogs’ digestive-system health, according to collaborative studies by Agricultural Research Service, university, and corporate scientists.

The carbs, predominantly a group known as “GGMOs”—short for galactoglucomannan oligosaccharides—are a key ingredient in Previda, an all-natural dietary ingredient marketed to makers of pet food, aquaculture feed, and other animal-nutrition products.

ARS chemist Neil P.J. Price began his studies of these fiber-rich carbs in 2007, working under the auspices of a cooperative agreement with Temple-Inland, a Texas-based producer of lumber, fiberboard, and other wood products made from loblolly, longleaf, and other kinds of …

Nourishing America’S Preemies Scientists Confront The Challenges Of Iv Feeding, Douglas G. Burrin, Marcia Wood

Agricultural Research Magazine

Each year, more than a half-million infants are born prematurely in the United States. Many of these preemies, particularly those whose tiny digestive systems are simply too underdeveloped to handle mother’s milk or infant formula, may need to be nourished exclusively via intravenous feeding, known as “total parenteral nutrition,” or TPN.

TPN solutions, usually administered at the hospital for anywhere from a few days to a month or more, provide essential nutrients broken down into a very basic form. This liquid is gently and continuously infused into the infant’s bloodstream, completely bypassing the digestive tract.

“TPN helps save the lives …

Viral Infection In Sheep Linked To Gene, Michael P. Heaton, Kreg A. Leymaster, Sandra Avant

Agricultural Research Magazine

The discovery of a gene associated with a persistent viral infection that causes an incurable disease—ovine progressive pneumonia (OPP)—in sheep has led to the development of a genetic test that can be used to help reduce the impact of the disease.

A slow-acting, wasting disease, OPP affects millions of sheep worldwide and is one of the most costly diseases to producers in North America. Previous research revealed that 36 percent of sheep operations and 24 percent of sheep tested in the United States were infected with ovine progressive pneumonia virus (OPPV)—lentivirus strains that target the immune system and cause OPP. …

Western Australian Farmer Survey 2011, Mandy Curnow, Andrew Van Burgel, Jackie Bucat, Anne Jones

Animal production and livestock published reports

DAFWA commissioned this WA sheep producer survey as an additional data set to the Cooperative Research Centre for Sheep Innovation (Sheep CRC) national producer survey. The data was collected by telephone survey in February and March 2011 for the purposes of gathering benchmark information on a range of sheep management practices. The data collected mostly relates to flock management during the 2010 season. The same survey will be run again in 2014 and a comparison of the information collected will be used to measure how producers have changed their practices during that time.

Producers were phoned and invited to contribute …

Studies On Nitrogen And Silicon Deficiency In Microalgal Lipid Production, Curtis Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Microalgae are single celled plants that inhabit aquatic and terrestrial environments across the planet. Many species are oleaginous, which means they are capable of producing oils, similar to many higher plants we are familiar with like canola, safflower and coconut. Different from higher plants, however, algae have simple structures that allow them to grow at very high rates. Due to these characteristics—oil production and rapid growth rates—algae are considered a promising future source of oil. Algal oils could be useful for production of food for people, feed for animals, biodiesel, detergents, and many other applications.

Algae have not been heavily …

Predicting Groundwater Trading Participation In The Upper Republican River Natural Resource District, Elizabeth M. Juchems

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

The goal of this thesis is to predict participation in groundwater trading and the directions of trades among participants. Specifically, the paper considers both formal and informal trading of groundwater used for crop irrigation purposes and attempts to identify those characteristics that predict the probability of trade participation and whether an individual is a buyer or seller of groundwater rights. While the public benefits from efficient use of groundwater include adequate stream flow in hydrologically connected areas and future use of groundwater supplies, there are significant private benefits to landowners especially in water-short areas. Groundwater trading can help move water …

Agricultural Development In The Northern Savannah Of Ghana, Tara N. Wood

Doctor of Plant Health Program: Dissertations and Student Research

Since declaring independence in 1957, the Republic of Ghana has become a stable constitutional democracy. Ghana’s economy has grown substantially over the past decade, yet remains primarily agrarian, accounting for 50% of the total employment and 25% of the country’s Gross Domestic Product. Smallholder rain-fed farming using rudimentary technologies dominates the agricultural sector accounting for 80% of total agricultural production. Approximately 90% of smallholder farms are less than two hectares in size, and produce a diversity of crops. The major crops cultivated in Ghana include numerous cereal, root and tuber, leguminous, fruit, vegetable and industrial crops. Maize is the most …
