Three types of hermetic storage systems were assessed for a period of 12 months: Purdue Improved Crop Storage (PICS) bags, including both 2- and 3-layer variants, and Ecotact® …

Assessing The Use Of Regenerative Agriculture In California Almonds As Climate Change Resilience, Skyler M. Seamons

Master's Projects and Capstones

The agriculture sector is responsible for 10% of the United States’ greenhouse gas emissions. In turn, anthropogenic climate change threatens crops. With its Mediterranean climate, California is the country’s largest agricultural-producing state. Many California crops are at risk due to increasing temperatures and changed precipitation patterns. This paper investigates regenerative farming techniques as a tool to protect California crops from a changing climate. Almonds are used as a case study to analyze the soil management practices, finances, and policies underlying regenerative agriculture in California. A literature review and comparative analysis are used to compare regenerative and conventional soil management practices …

Impact Of Temperature On Children’S Nutrition: A Comparative Study Of Three Ecological Regions Of Nepal, Prakriti Shakya

Master's Theses

Nutrition obtained during the growth period of childhood significantly influences long-term well-being and overall productivity, ultimately contributing to the economy of a society. However, weather shocks can wreak havoc by damaging crops, changing yields of important crops and disrupting market access, which directly impacts the food intake of both adults and children. When these adverse events occur during childhood, short term and long term inadequacy in nutrition as well as disease incidence can cause malnutrition leading to stunted growth and cognitive impairment that may persist into adulthood, affecting the labor market and increasing health expenditure. To address this issue, we …

The Impact Of Index Based Livestock Insurance (Ibli) On Child Nutrition In Marsabit County, Kenya, Jackson Kadyampakeni

Master's Theses

The study uses six rounds of Index-Based Livestock Insurance (IBLI) panel surveys (2009 – 2015) for Northern Kenya’s Marsabit county to investigate the impact of IBLI on child nutrition and household food security. We employ Ordinary Least Squares (OLS) and Instrumental Variable (IV) regressions to account for potential endogeneity in IBLI uptake. The results indicate that while IBLI uptake significantly improves the intake of key nutrients such as Vitamin A, protein, iron, and fruits and vegetables, it does not translate into significant improvements in child nutrition status, as measured by Mid-Upper Arm Circumference (MUAC) z-scores. Significant negative effects of age …

An Exploration Of Learning And Teaching Methods In Agricultural Extension, Jeremy Levinson, Dave Lamie, Michael Vassalos, Chris Eck, Juang Chong, Francis P. F. Reay-Jones

Journal of Extension

Abstract

The Train-the-Trainer approach is widely used in Cooperative Extension education to efficiently disseminate research-based information to many clientele groups, including farmers. This paper compares the traditional Train-the-Trainer model to a comprehensive Collaborative Train-the-Trainer model and discusses weaknesses of the traditional model that are addressed in the Collaborative model. Sources of information used by farmers (growers) and overall effectiveness were measured through a survey instrument created and distributed to farmers in South and North Carolina. The Collaborative Train-the-Trainer model, which emphasizes peer-to-peer interaction and feedback loops, represents an enhanced approach for conceptualizing and implementing Extension educational programs.

This tool can be used regardless of geographic location and will benefit a diverse audience including Extension educators, equine business owners, and horse owners.

Ancient Wisdom, Modern Prosperity: Harnessing Traditional Ecological Knowledge To Revitalize Australia's Economy, Environment, And Human Wellbeing, Annabelle L. Baulch

Student Theses 2015-Present

This paper explores the traditional knowledge of Australia’s Indigenous people and how it can improve Australia's environment, health, and economic prosperity to shape a more sustainable future. Indigenous Australians managed the land for thousands of years; however, being forced off the land following European colonization resulted in terrible cultural, social, and environmental disruption for Aboriginal Australians and made conservation efforts difficult. Wildfires, imported species, mining, and agriculture is steadily destroying the Australian ecosystem, contributing to climate change, species extinction, and gaps in our cultural and ancestral knowledge. Chapter One overviews Australia's environmental issues; it uses quantitative data to explore the …

Does Rural Transformation Affect Rural Income Inequality? Insights From Cross-District Panel Data Analysis In Bangladesh, Al Amin Al Abbasi, Subrata Saha, Ismat Ara Begum, Maria Fay Rola-Rubzen, Andrew M. Mckensie, Mohammad Janghir Alam

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Rural transformation plays a crucial role in enhancing the income and employment prospects of the rural labor force. We investigate the effects of rural transformation on rural income inequality at the district level in Bangladesh using data from five years of nationally representative Household Income and Expenditure Surveys. The Gini coefficient is used to measure rural income inequality. In contrast, the share of high-value agricultural outputs and the share of rural non-farm employment are used as indicators of rural transformation. We find that rural income inequality is positively associated with the share of high-value agricultural outputs and the share …

Evaluating The Effect Of Garden-Based Education On Young Learners’ Preferences For And Willingness To Try Healthy Food, Sierra Gregory

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Childhood obesity in American children has tripled in the last 20 years, and 85% of current healthcare spending is linked to diet-related diseases. The consumption of highly processed foods is linked to these trends and makes up more than half of an average American youths’ diet. Reducing the consumption of highly processed foods in children’s diets can be addressed, in part, by addressing childhood neophobia (willingness to try new foods) associated with whole foods like fruits and vegetables. Influence over behavioral areas such as nutrition and in early childhood is essential to long-term sustained health, and garden-based interventions shows promise …

Navigating Challenges For Locally Produced Food, Paul Cook

SACAD: Scholarly Activities

There is much interest in locally produced food and the benefits it can have on communities across the state of Kansas. By interviewing city managers, we have identified some of the unique factors and challenges that city officials face when considering their community’s local food systems. Through interview and survey data, we sensed that there is a desire for more local food in communities but lack of resources, lack of policies and the nature of large commodity agriculture in Kansas appear as challenges. Ad-hoc groups coming from schools, churches, and committees at the county level make up the majority of …

Climate Insurance - Using Weather Data And Ai To Manage Agricultural Risk In Developing Countries, Scott A. Denning

All Theses

Weather index-based crop insurance has promised to be a lifeline for low-income farmers in developing countries. However, high-basis risk, high administration costs, and low willingness to pay have caused the demise of many pilot programs. Building onto the principles of index insurance we propose Climate Insurance, a new form of insurance based on predictive crop models that overcomes most of the primary objections of index insurance while achieving its goals of low administration costs, greatly reduced adverse selection, and the elimination of moral hazard. The crop model presented herein utilizes an artificial neural network to predict county- level yield per …

Heterogenous Impacts Of Pathogenic Avian Diseases On Global Poultry Production, Elsbeth Hamilton

Graduate Theses and Dissertations

Globally, poultry is one of the most versatile and cost-effective sources of animal-based protein. Due to its wide variety of uses and variability of growing styles, poultry production is applicable in nearly every country. With the increase of scale and concentration of production, pathogenic diseases have decreased the efficiency of production through worsened feed conversion, morbidity, and mortality. In addition to physiological health, climate largely impacts the suitable conditions for growing. With more extreme climate events, locations once ideal for poultry are less efficient due to increased resource cost. This analysis seeks to determine the heterogeneity of production and the …
