Comparing Organic And Conventional Yield Responses To Climate Variations, Joost Wilken Meyer
Comparing Organic And Conventional Yield Responses To Climate Variations, Joost Wilken Meyer
Graduate Theses and Dissertations
This thesis compares the responses of organic yields and conventional yields towards climate variations. To achieve this objective, weather variables such as growing season weather conditions (average temperature, precipitation, cloud cover, relative humidity, drought index), weather anomalies, the occurrence of severe or extreme droughts and excessive rainfalls, are combined with 23 data sets gathered from previous studies that compare organic and conventional yields from the same location and time periods. To narrow the scope, the thesis focuses on soybean, maize, and wheat production in Europe and North America. Study-level fixed-effects models are used to control for any time-invariant factors such …
Poultry Labeling: Knowledge, Perceptions, And Preferences Among Adolescents, Eleni L. Parsons
Poultry Labeling: Knowledge, Perceptions, And Preferences Among Adolescents, Eleni L. Parsons
Graduate Theses and Dissertations
The purpose of this study was to determine the knowledge, perceptions, and preferences of adolescents in regard to the labeling of poultry products. The theory of planned behavior (TPB) and Elaboration Likelihood Model (ELM) were used to display the relationship of perceptions, attitude, and behavior intentions. Quantitative data was collected in a descriptive research design. The population included youth, aged 14 – 18 years, involved in the Arkansas 4-H State O’Rama competition (N = 400). The sample (n = 80) ensured a 90% confidence interval of the population. Data was collected by administering paper surveys that addressed four product labels …
Consumers’ Willingness To Pay For Hydroponic Lettuce, Daniel Gilmour
Consumers’ Willingness To Pay For Hydroponic Lettuce, Daniel Gilmour
Graduate Theses and Dissertations
With continued advances in hydroponic plant production technology, an increasing number of farms have begun using hydroponic techniques to grow leaf lettuce and other food crops in a controlled environment. Recent controversy about the ongoing inclusion of hydroponics in the USDA organic program has highlighted uncertainty about marketing for hydroponic crops. In November 2017, the National Organic Standards Board voted not to recommend that hydroponic farms be banned from applying for organic certification. Since then, continued controversy has led a group of organic producers to start an additional independent certification program that would exclude hydroponic crops. While hydroponic production may …
Purchaser Preferences On Carbon Labels: Conventional Vs. Organic Milk, Mustafa Ozkan
Purchaser Preferences On Carbon Labels: Conventional Vs. Organic Milk, Mustafa Ozkan
Graduate Theses and Dissertations
Over the past several years, there has been growing attention concerning global warming/climate change and how humans are contributors. It is known that agricultural production is a main contributor of greenhouse gas emissions and the livestock sector is particularly significant because it is quoted as having between 3 and 18% of greenhouse gas emissions measured in CO2 equivalent pending different assumptions. Due to this, carbon footprint labeling has been described as a potential tool to inform consumers about greenhouse gases associated with food products and assist them with the necessary information to purchase products that help reduce greenhouse gas emissions. …
