Propensity-Score Matching Beginning And Experienced Farmers On Stress And Coping Mechanisms To Predict Suicidal Ideation, Anne Montgomery, Stephanie M. Basey, Chris T. Scoggins, Lily Baucom

Georgia Public Health Association Annual Meeting and Conference

This presentation is an extension of a roundtable from last year; we added propensity-score matching thanks to suggestions from the roundtable:

The suicide rate among farmers is much higher than that of the overall working population. Literature on farmer mental health in Georgia has been scarce and mostly focused on farmer suicide. This study looks at the influence of being a beginning farmer (less than 10 years of experience) on farm-related stressors and coping mechanisms.

This cross-sectional study inventories mental well-being, stressors, and coping mechanisms for different types of farmers. Participants (N=1,328) were asked demographics, household composition, work descriptors, healthcare …

Gender-Based Differences In Stress And Coping Among Farmers: A Cross-Sectional Study With Propensity Score Matching, Anne Montgomery, James B. Dunaway, Stephanie M. Basey, Chris T. Scoggins, Lily R. Baucom

Georgia Public Health Association Annual Meeting and Conference

This cross-sectional study compares the mental health experiences of male and female farmers, with a particular focus on stress levels, stressors, and coping mechanisms. The research aims to shed light on gender-based differences in stress experiences and coping strategies among agricultural workers. The study involved 1,394 farmers (67.7% male, 32.3% female) from Georgia, USA, who completed an online survey on aspects of mental well-being.

Findings indicate that female farmers were more likely to hold farm manager roles and less likely to be farm owners. Notably, a higher proportion of female farmers were first-generation farmers, indicating potential unique challenges for this …

IGC Proceedings (1997-2023)

The PLANTS database provides basic plant information to the United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS), its clients, cooperators, and the general public via the World Wide Web (Fig. 1). The foundation of PLANTS is a taxonomic backbone (checklist) of the vascular and nonvascular plants of North America (north of Mexico) and United States territories in the Caribbean and Pacific regions. Attribute data are appended to this backbone pertaining to distribution, vegetative specifications, nativity, federal and state status, crop data, growth form, growth parameters, species abstracts, and images.

Development Of Forage Curriculum For Extension Educators In The Southeast Usa, L. S. Silva, L. Dillard, K. Mullenix, M. Wallau, J. J. Tucker, C. Vasco

IGC Proceedings (1997-2023)

In the Southeast USA, livestock production is one of the largest agricultural activities, and forages are the primary feed source. Most livestock systems are highly dependent on off-farm inputs to support forage production and animal performance, which elevates production costs and the activity's carbon footprint. There is a strong need to develop forage educational resources to enhance productivity, environmental sustainability, resilience, and profitability of agricultural systems in the region. This multi-disciplinary initiative was a collaboration among several land-grant Universities across the region. The objective was to develop decision tools and provide in-classroom training associated with hands-on demonstrations to Extension agents …

The Detection Of Putative Recessive Lethal Haplotypes In Irish Sheep Populations, Rory Mcauley

ORBioM (Open Research BioSciences Meeting)

In livestock populations, recessive lethal alleles are a known contributor to poor reproductive performance due to embryonic death in homozygous individuals. Despite their lethal effect in the recessive form, these alleles may be maintained at high frequencies among carrier animals because of their positive pleiotropic effects on economically important traits. Although several such recessive alleles have been identified in cattle and pig populations, limited studies have been completed in sheep, and none within Irish sheep populations. Genotype data for 69,034 animals from five major Irish sheep breeds genotyped on a variety of panels was available for this study. Only animals …

My Summer Working With Two-Spotted Spider Mites, Renée A. Smith

Undergraduate Student Research Internships Conference

Two-spotted spider mites are a polyphagous pest, capable of eating a magnitude of food crops which causes a large problem for Canadian agriculture. Their ability to consume various crops stems from their ability to adapt to various chemical defence mechanisms. This ability allows them to acquire resistance to many commonly used pesticides. This has resulted in large infections in Canadian farms with few options to prevent the pests from affecting crop yields. Take a look at my project if you'd like to see how the Grbic lab is working to combat this issue using genetic engineering techniques!

Caricrop: Can A Digital Payment System Support Fairer Agricultural Trade?, Kruakae Pothong, Larissa Pschetz, Arlene Bailey, Billy Dixon

DRS Biennial Conference Series

What difference can new technologies make for small-scale farmers facing a multitude of uncertainties that could affect not only the value of their crops but also when and whether they get paid? To understand how Distributed Ledger Technologies such as Blockchains, could be leveraged to address such uncertainties in agricultural trade, we engaged small-scale farmers in a problem delineation exercise and designed CariCrop, a payment system and currency that specifically addresses the issue of delayed payments. We investigated the potential impact of this system through immersive drama and deliberative workshops. We found that although digital payment systems can give farmers …

Debe Ser Dirigida: Theories Of Community Organizing For Research Management In The Context Of Rural Ecuador, Meghan Edwards

Student Symposium

This research analysis and literature review discusses the factors that mobilize individuals to take an active role in community-led resource management. After reviewing major contemporary theories of resource management such as Elinor Ostrom's polycentric theory, CPR theories, and Arnstein's ladder, the essay then applies these theories to the context of the Quijos Valley in Ecuador, where the author conducted informal interviews with community members both involved and not-involved in managing fragile soil ecosystems. The literature review considers the idea that individuals are more likely to take an active role in research management when there are strong community bonds, and highlights …

Conversion Of Forest To Agro-Silvo-Pastoral System – Montado – In Mediterranean Environments, J. Potes, F. Jorge, T. Montes, D. Palha

IGC Proceedings (1997-2023)

The Mediterranean environment regions are characterized by climate and soil specificities that justify low productive capacity for primary production when compared to other environments on earth. The Mediterranean forests are essentially formed by trees and shrubs. The shrubs are the perfect fuel to feed the forest fires that occur in a natural and cyclical manner in these environmental conditions. Therefore, the Mediterranean Systems of Agriculture have evolved to control the shrubs and the extensification of the systems because of low productivity. Sustainability is achieved by increase of productivity through improvement of the soil and irrigation. The application of these principles …

Tonal Variation In An Agricultural Field In Greene County, Ohio, Kenan Estes

Scholars Symposium

This project examined the tonal differences in an agricultural field in Cedarville, Ohio to determine what environmental or historical factors contributed to the distinct light and dark patches when observed using aerial imagery. Historical photos going back as far as 1948 consistently show these tonal differences. Lidar data was gathered and turned into a topographic map which closely corresponded to the tonal patterns. Soil samples taken from six locations to a depth of three feet indicated that the topsoil color closely matches the light and dark colors seen from the air. These samples also match the soil color and composition …

The ease of use and accessibility of these devices has paved the way for many technological advancements, especially in the agricultural sector. In this study, the impact of piezoelectric, electrochemical, optical, and molecular biosensors in agricultural settings were analyzed using a bibliometric analysis software called VOSviewer. Various parameters and data sets such as biosensor trends, keyword relationships, and biosensor citation prevalence were used. The created maps showed that in the variable for co-authorship, Chinese …

Genetically Modified Organisms Are Important But Also Controversial, Masen Pelletier

Thinking Matters Symposium

Genetically modified organisms (GMOs) are organisms containing a set or multiple sets of genes that have been introduced into the organism using laboratory techniques. In the instance of agriculture, the genes introduced provide advantages for the farmer and consumer by yielding plants that produce greater yields, longer growing seasons, longer shelf lives, greater concentrations of vitamins or add additional vitamins that are novel to the plant. There are two general ways that GM (genetically modified) crops are produced: the addition or removal of genes. This review focuses on an example of each strategy. An example of the latter is GM …

A Group Model Building Approach For Climate Change Adaptation Of Agricultural Systems In Northeast Lower Saxony, Rodrigo Valencia

International Congress on Environmental Modelling and Software

Climate change is expected to affect water availability for agriculture and increase the risk of crop loss. While in North East Lower Saxony (NELS) an intensification of irrigation might be a temporary solution, a long-term increase in water extraction, especially during drought periods, is not a sustainable option. Based on this issue, we implemented a participatory system dynamics approach, namely Group Model Building (GMB), to develop a qualitative system dynamics model (QSDM) describing the agricultural system and its relation to water resources in the study region. Through the development of such a model, we seek to understand the complexity of …

Demonstration Of Agricultural Progress On Water Quality: Modelling The Effectiveness Of The Usda-Nrcs Eqip Conservation Practices, Tyler Wible

International Congress on Environmental Modelling and Software

Water quality degradation is one of the world’s most pressing environmental concerns. As regulations tighten on most point source pollutants, many are now looking to nonpoint source improvements for water quality. Of particular interest is the impact of agricultural best management practices (BMPs) on water quality through incentive and voluntary programs. The Natural Resources Conservation Service (NRCS) of the United States Department of Agriculture (USDA) has administered the Environmental Quality Incentives Program (EQIP) under the Farm Bill to assist producers with applying sustainable on-farm conservation practices. However, there has been few if any studies quantifying the benefits to water quality …

Integrating Remote Sensing And Expert Knowledge For Agricultural Monitoring, Ana Stritih Stritih

International Congress on Environmental Modelling and Software

Increasingly available remote sensing products can provide valuable up-to-date information to land managers and decision-makers. For example, land-use monitoring can support the implementation of agricultural policies, such as direct payments, and provide timely information on risks such as erosion. However, local experts and stakeholders already have a wealth of knowledge about the land they manage, and integrating this knowledge can help improve the accuracy and usability of remote sensing products. We are developing a tool for the agricultural administration of the Swiss Cantons of Bern, Solothurn, and Fribourg, which aims to use remote sensing data to monitor agricultural land use …

A Leverage Points Analysis Of A Qualitative System Dynamics Model For Climate Change Adaptation In Agriculture, Sabine Egerer

International Congress on Environmental Modelling and Software

In the area of Northeast Lower Saxony (NELS), Germany, climate model projections until the end of the century show rising temperatures throughout the year, slightly lower precipitation and higher evaporation rates during summer when water for agriculture is highly demanded. The changing climate conditions are likely to cause a substantial net water deficit. Responding to these challenges, we analyze a qualitative system dynamics model (QSDM) of the agricultural sector in NELS that is based on a participatory modeling approach. Stakeholders were directly involved in the model building process through individual interviews and by co-developing a common group model. We develop …

Global Sensitivity Analysis Of A Generic Agent-Based Approach To Model Diverse Behaviour Of Farmers, Robert Huber

International Congress on Environmental Modelling and Software

We present a global sensitivity analysis of a generic agent-based modelling approach called FARMIND (FARM Interaction and Decision-making). The purpose of the model is to simulate agricultural production decisions. FARMIND reflects the heterogeneity in farmers decision-making processes based on standard and behavioural economic concepts. The key functionality of the model is to consider farmers’ individual characteristics such as attitudes and risk preferences and the farmers’ social network in the decision-making process. The model allows to inject diverse behaviour into existing bio-economic simulation models and is intended to improve the understanding and explanation of farmer’s decision-making trough hypothesis testing. Applications of …

Strengths And Weaknesses Of National Agricultural Research Systems: Attracting The Next Generation Of Grasslands Researchers, James E. Pratley, Casper W. Roxburgh

IGC Proceedings (1997-2023)

In the 1960s and 1970s the world faced up to the poverty and hunger facing a significant proportion of the global population, which at the time was around 4 billion people. The efforts of Norman Borlaug and the Green Revolution resulted in food production increasing as the technologies and knowledge known at the time were directed to that task. The success of the Green Revolution was such that governments and the world communities turned attention to other issues and agricultural development slid down the list of priorities. The world population is now over 7 billion and projected to be over …

Quantifying The Concentration Of 33-Mer In Wheat Flour, Abigail E. Rivas, Kaylee A. Howell, Robert Paris

Scholars Symposium

Celiac Disease is a type IV hypersensitive response to gluten caused by HLA-DQ2 or HLA-DQ8 T-cell presentation, initiating destruction of intestinal epithelial cells. Currently, the only remedy for those suffering from celiac disease is the complete elimination of all gluten from the diet. Studies indicate that an indigestible fragment of the gluten molecule, alpha-gliadin subcomponent 33-mer, rich in proline and glutamine, is responsible for the hypersensitivity response. Determination of 33-mer concentration in wheat lines could be beneficial to the future development of wheat lines with reduced 33-mer concentration. In this study, gliadin protein from wheat flour was extracted and separated …

Panel 3 Paper 3.3: Māori Ancestral Landscapes And The Celebration Of Prowess In Cultivation And Resource Gathering: Digesting Natural Heritage As An Expression Of Culture, Xavier Forde

ISCCL Scientific Symposia and Annual General Meetings // Symposiums scientifiques et assemblées générales annuelles de l'ISCCL // Simposios científicos yy las Asambleas Generales Anuales

The provision of food and other natural resource for subsistence is celebrated in the histories of Māori tribes, in episodes relating to the ancestors who brought crops from Hawaiki in their migration to Aotearoa New Zealand, or who demonstrated prowess in the cultivation or gathering of resource. The oral histories of these ancestors and their feats of provision are still evidenced in aetiological stories, place names, and expansive archaeological fields, and artefacts that shape cultural landscapes, map out the natural resource around the country, and continue to act as a repository of indigenous knowledge today.
