“Stay-green” crop phenotypes have been shown to impact drought tolerance and nutritional content of several crops. We aimed to genetically describe and functionally dissect the particular stay-green phenomenon found in chickpeas with a green cotyledon color of mature dry seed and investigate its potential use for improvement of chickpea environmental adaptations and nutritional value. We examined 40 stay-green accessions and a set of 29 BC2F4-5 stay-green introgression lines using a stay-green donor parent ICC 16340 and two Indian elite cultivars (KAK2, JGK1) as recurrent parents. Genetic studies of segregating populations indicated that the green cotyledon trait is controlled by a …

Payment For Ecosystem Services: Incentives To Support Environmental Quality & Farming In Vermont, Stephen Posner, Taylor Ricketts, Eric Roy

Reports and Policy Briefs

Environmental quality is an ongoing concern in the Lake Champlain Basin. Vermont farmers are in a unique position to manage land in a way that maintains and improves environmental quality. A payment for ecosystem services (PES) program for Vermont would both support the economic vi- ability of Vermont farms and incentivize farmers to improve water quality and soil health. How- ever, conceptual and practical implementation challenges remain.

H-2a Temporary Agricultural Workers On Small Farms: Case Study Observations And Lessons Learned, Barrett Vaughan, Lerosha Ford, Silvia Brashier, Miles Robinson

Professional Agricultural Workers Journal

Abstract

The experiences of two small farmers in their efforts to employ and retain temporary agricultural workers through the H-2A Program were documented through an illustrative case study. Interviews of the farmers were conducted regarding the measures that they had to take in preparing for, employing, housing, hosting, managing, and financing the workers. These temporary agricultural workers were sought in support of these farmers’ continued participation in an initiative to assist small and limited-resource farmers in supplying produce to a major retailer. It was concluded that there are at least four priority areas for employing H-2A workers: planning, applying, maintaining …

Toward Effective Rural Community Development In Black Belt Counties: Conceptual And Methodological Issues, Andrew Zekeri

Professional Agricultural Workers Journal

Abstract

The objectives of this paper are to (1) specify what “rural”, “community”, and “development” mean, and (2) what should be the essential steps to be taken to achieve an effective rural community development. Rural is a territorial concept, and it means an extent of dispersion of people in a local ecology. Community is a natural disposition among people who interact with one another on different matters that compromise a common life. Development is an organized intentional effort of local people to work together towards a shared goal. Community development is building the capacity of community residents to act effectively …

Knowledge, Attitudes, Beliefs And Behaviors Regarding Fruits And Vegetables Among Cost-Offset Community-Supported Agriculture (Csa) Applicants, Purchasers, And A Comparison Sample, Karla L. Hanson, Leah C. Volpe, Jane Kolodinsky, Grace Hwang, Weiwei Wang, Stephanie B. Jilcott Pitts, Marilyn Sitaker, Eretii Timeon, Alice S. Ammerman, Rebecca A. Seguin

College of Agriculture and Life Sciences Faculty Publications

Community-supported agriculture (CSA) participation has been associated with high fruit and vegetable (FV) consumption, which may be due to better access to FV for CSA purchasers, or to positive knowledge, attitudes, and beliefs (KAB) regarding healthy eating among CSA applicants. The objective of this study was to examine KAB and consumption, in association with application to a cost-offset CSA (CO-CSA) program, and with CO-CSA purchase among applicants. We conducted a cross-sectional survey of CO-CSA applicants and a comparison sample in August 2017. All respondents were English-reading adults with a child 2–12 years old and household income of < 185% of the federal poverty level. Among CO-CSA applicants, some were CO-CSA purchasers (n = 46) and some were not (n = 18). An online comparison sample met equivalent eligibility criteria, but had not participated in CSA for three years (n = 105). We compared CO-CSA applicants to the comparison sample, and compared purchasers and non-purchaser sub-groups, using Mann- Whitney U tests and chi-square analysis. CO-CSA applicants reported better knowledge, selfefficacy, home habits, and diet than the comparison sample. Among applicants, CO-CSA purchasers and non-purchasers had equivalent KAB, but children in purchaser households had higher FV consumption than in non-purchaser households (4.14 vs. 1.83 cups, P = 0.001). Future research should explore associations between CO-CSA participation and diet using experimental methods.

Population Genomic Analysis Of Mango (Mangifera Indica) Suggests A Complex History Of Domestication, Emily J. Warschefsky, Eric J.B. Von Wettberg

College of Agriculture and Life Sciences Faculty Publications

Trust Humans have domesticated diverse species from across the plant kingdom, yet much of our foundational knowledge of domestication has come from studies investigating relatively few of the most important annual food crops. Here, we examine the impacts of domestication on genetic diversity in a tropical perennial fruit species, mango (Mangifera indica). We used restriction site associated DNA sequencing to generate genomic single nucleotide polymorphism (SNP) data from 106 mango cultivars from seven geographical regions along with 52 samples of closely related species and unidentified cultivars to identify centers of mango genetic diversity and examine how post-domestication dispersal shaped the …

A Comparative Analysis Of Governance And Leadership In Agricultural Development Policy Networks, Jessica Rudnick, Meredith Niles, Mark Lubell, Laura Cramer

College of Agriculture and Life Sciences Faculty Publications

Agricultural development initiatives feature many public and private organizations working together across sectors and scales to pursue the goals of food security and climate resilience. Policy networks are considered a crucial ingredient for the learning and cooperation needed to effectively implement agricultural development projects and increase community resiliency, yet very little comparative empirical data has been collected to assess where and how these networks operate. We contribute to filling this gap by characterizing the governance and leadership patterns within agricultural development policy networks that connect organizations working on climate resilience and food security activities in 14 smallholder farming communities across …

Evaluation Of Drought Tolerance In Arkansas Cowpea Lines At Seedling Stage, Qirui Cui

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Cowpea [Vigna unguiculate (L.) Walp.] is not only a healthy, nutritious and versatile leguminous crop, it also has a relatively high adaptation to drought. Researches have shown that cowpea lines have a high tolerance to drought, and many of them can survive over 40 days under very hot and dry conditions. The cowpea (Southern pea) breeding program at the University of Arkansas (UA) has been active for over 50 years and has produced more than 1,000 advanced breeding lines. And the purpose of this study is to evaluate the drought-tolerant ability in Arkansas cowpea lines and use the drought tolerant …

The Farmers’ Federation: Regional Racial Mythologies As Agricultural Capital, Jama Mcmurtery Grove

Graduate Theses and Dissertations

In 1927, the Farmers’ Federation agricultural cooperative in Western North Carolina launched an organization to solicit funds from wealthy donors. The money raised through philanthropic campaigns enabled the cooperative to fund large-scale agricultural projects, which helped members navigate the dramatic agricultural transformations of the early twentieth century. Although the cooperative advocated a progressive program of business-minded, scientific farming, its leadership modified programs to reflect farmer members’ limited resources and the realities of mountain production. As a result, the co-op provided a crucial bridge between white farmers and new methods of agricultural production that reached deep into peoples’ familial and productive …

Resisting Industrial Food Systems On The Web: How Non-Profit Organizations Use Digital Technology For Sustainability Education, Aleksandr Segal

Dissertations, Theses, and Capstone Projects

This thesis examines the link between how community-based organizations use digital tools with the fundamentally resistance-based philosophy that these organizations have at the core of their mission. It aims to uncover how non-profit organizations (NPOs) that work in community development through food and agriculture use digital tools, and how their digital communication strategies relate to issues of resistance to neoliberalism and industrialization in the food and agriculture sectors.

Using a foundation of existing literature on food and agriculture, climate change and waste management, critical theory, and technology in pedagogy, this thesis will contextualize how non-profits resist neoliberal regimes of de-traditionalization …

Spatial Considerations For Implementing Two Direct-To-Consumer Food Models In Two States, Marilyn Sitaker, Jared T. Mcguirt, Weiwei Wang, Jane Kolodinsky, Rebecca A. Seguin

College of Agriculture and Life Sciences Faculty Publications

To open new markets, some farmers have adapted direct-to-consumer (DTC) models, such as Community Supported Agriculture (CSA), to reach new settings or audiences. We compared sociodemographic and geospatial contexts to farmers' experience with one of two DTC innovations: a cost-offset CSA for low-income families and food boxes distributed through rural convenience stores. We geocoded addresses of thirteen farms and DTC pickup sites in two U.S. states (Vermont and Washington) and calculated road network distances from pickup to supermarket, farmers' market, and farm. We compiled Census block-level demographic and transportation data, and compared it to postseason interviews to explore the effect …

Living With Bees: A Look Into The Relationships Between People And Native Bees In Western Nepal, Alexandra Cobb

Independent Study Project (ISP) Collection

Nepal is home to four native species of bees and as many methods to produce and gather their honey. In recent decades, several domestic and international organizations and governments have researched bee populations and provided financial and technical support through subsidies, trainings, and materials in efforts to conserve biodiversity and develop beekeeping in Nepal. However, little attention has been given to human-bee connections, the factors that shape them, and how they can provide a lens for understanding human-environmental relationships. Thereby, this study aims to exploring a selection of people’s experience with beekeeping and perspective of bees in order to illuminate …

Regenerative Grazing And The Benefits Of Livestock On Soils In Northern New South Wales, Raymond Mooney

Independent Study Project (ISP) Collection

Conventional cattle grazing has received criticism for environmental degradation in the past. Regenerative grazing and the principles of regenerative agriculture show encouraging signs that proper livestock management and planned grazing can reverse degradation and mitigate climate change. An emphasis on soil health and increasing soil carbon and organic matter levels reveals positive feedback for environmental health, the economic security of farmers, and nutritional health of consumers.

In this study I looked to investigate the benefits of regenerative agriculture, reasons why it is being practiced, and the extent it is practiced within the grazing in comparison to traditional methods within Northern …

The Impacts Of Tourism On Subak, Sawah, And The Environment, Reiley Adelson

Independent Study Project (ISP) Collection

In this paper I wish to explore the topic of Sawah, Subak, and the impact tourism has on both of these important parts of Balinese culture. By starting with the history of subak, moving into the Green Revolution, then into the start of mass tourism, and coming all the way up until today, I would like to see how subak has changed and developed or how it hasn’t. I would also like to get a sense of what people see for the future of farming in Bali. To go about this, I talked with rice farmers, who are being directly …

Humanitarian Assistance In Protracted Emergencies: Rethinking The Role Of Food Aid In Adjumani, Victoria Puglia

Independent Study Project (ISP) Collection

Humanitarian food assistance is incredibly susceptible to funding cuts, which reduces the quantity of food available to refugees. If refugees depend solely on food aid for survival, the implication of reductions is increased food insecurity at a household level. The Government of Uganda champions a self-reliance strategy that has failed to support refugees to the desired extent, especially when food rations are low. This study aims to assess the impact of humanitarian food assistance on the socioeconomic structures of refugee settlements in Adjumani, Uganda to understand the consequences of unstable food aid. The research was conducted over a four-week period. …

Local Perceptions Of Cannabis And Cannabis Laws In Morocco: Unpacking Past Laws, Moroccans' Perceptions, And Exploring Organizational Efforts, Shadae Tingman

This research will explore many aspects of cannabis in Morocco. There is much literature that exists surrounding the agricultural, economic, and political implications of cannabis, but this research will focus on social perceptions of cannabis and cannabis laws of local Moroccans. This research will explore past government attempts to legalize marijuana and why they did not pass. It will also explore the work of local youth organizations (that focus on cannabis) to understand what they …

Seeing Is Not Always Believing: Crop Loss And Climate Change Perceptions Among Farm Advisors, Meredith T. Niles, Sarah Wiener, Rachel E. Schattman, Gabrielle Roesch-Mcnally, Julian Reyes

College of Agriculture and Life Sciences Faculty Publications

As climate change is expected to significantly affect agricultural systems globally, agricultural farm advisors have been increasingly recognized as an important resource in helping farmers address these challenges. While there have been many studies exploring the climate change belief and risk perceptions as well as behaviors of both farmers and agricultural farm advisors, there are very few studies that have explored how these perceptions relate to actual climate impacts in agriculture. Here we couple survey data from United States Department of Agriculture farm service employees (n = 6, 514) with historical crop loss data across the United States to explore …

Non-Linear Regression Models For Time To Flowering In Wild Chickpea Combine Genetic And Climatic Factors, Konstantin Kozlov, Anupam Singh, Jens Berger, Eric Bishop-Von Wettberg, Abdullah Kahraman, Abdulkadir Aydogan, Douglas Cook, Sergey Nuzhdin, Maria Samsonova

College of Agriculture and Life Sciences Faculty Publications

Background: Accurate prediction of crop flowering time is required for reaching maximal farm efficiency. Several models developed to accomplish this goal are based on deep knowledge of plant phenology, requiring large investment for every individual crop or new variety. Mathematical modeling can be used to make better use of more shallow data and to extract information from it with higher efficiency. Cultivars of chickpea, Cicer arietanum, are currently being improved by introgressing wild C. reticulatum biodiversity with very different flowering time requirements. More understanding is required for how flowering time will depend on environmental conditions in these cultivars developed by …

Food And Earth Systems: Priorities For Climate Change Adaptation And Mitigation For Agriculture And Food Systems, Ana Maria Loboguerrero, Bruce M. Campbell, Peter J.M. Cooper, James W. Hansen, Todd Rosenstock, Eva Wollenberg

Rubenstein School of Environment and Natural Resources Faculty Publications

Human activities and their relation with land, through agriculture and forestry, are significantly impacting Earth system functioning. Specifically, agriculture has increasingly become a key sector for adaptation and mitigation initiatives that address climate change and help ensure food security for a growing global population. Climate change and agricultural outcomes influence our ability to reach targets for at least seven of the 17 Sustainable Development Goals. By 2015, 103 nations had committed themselves to reduce greenhouse gas emissions from agriculture, while 102 countries had prioritized agriculture in their adaptation agenda. Adaptation and mitigation actions within agriculture still receive insufficient support across …

Now I See: Photovisualization To Support Agricultural Climate Adaptation, Rachel E. Schattman, Stephanie Hurley, Martha Caswell

College of Agriculture and Life Sciences Faculty Publications

Published with license by Taylor & Francis Group, LLC. To remain viable, agricultural producers will need to adapt to changing climatic conditions in coming decades. Agricultural advisers play an important role in helping producers decide to adopt appropriate adaptation practices. Photovisualizations have the potential to complement currently utilized outreach and education strategies. This research uses a focus group approach to explore (1) whether photovisualizations can aid in decision-making about climate change adaptation, and (2) what characteristics of photovisualizations are most effective at conveying spatial aspects of adaptation practices. We found that photovisualizations generate rich discussions about ecological and economic effects …

Does Household Capital Mediate The Uptake Of Agricultural Land, Crop, And Livestock Adaptations? Evidence From The Indo-Gangetic Plains (India), Sameer H. Shah, Courtney Hammond Wagner, Udita Sanga, Hogeun Park, Lia Helena Monteiro De Lima Demange, Carolina Gueiros, Meredith T. Niles

College of Agriculture and Life Sciences Faculty Publications

Farmers in the Indo-Gangetic Plains produce much of the wheat and rice grown in India. However, food production and millions of farm-based livelihoods in this region will continue to be adversely affected by hydro-climatic change and variation, reduced land productivity, and declining groundwater levels. Thus, agricultural adaptations are essential for protecting and improving upon intersecting goals of food security, poverty alleviation, and wellbeing. Household “capital” (e.g., natural, human, financial, physical, and social) is commonly cited as an indicator of livelihood adaptability and innovation. We develop a series of mediated structural equation models to empirically evaluate the validity of capital as …

Scaling Up Sustainability In Commodity Agriculture: Transferability Of Governance Mechanisms Across The Coffee And Cattle Sectors In Brazil, R. Hajjar, P. Newton, D. Adshead, M. Bogaerts, V. A. Maguire-Rajpaul, L. F.G. Pinto, C. L. Mcdermott, J. C. Milder, E. Wollenberg, A. Agrawal

Rubenstein School of Environment and Natural Resources Faculty Publications

A number of governance mechanisms address socio-environmental challenges associated with commodity agriculture in tropical forested countries. Governance mechanisms that prove effective in one agricultural sector are often applied to other sectors as well. For example, voluntary certification programs have been adopted by producers of commodities as diverse as beef, coffee, palm oil, and soy. However, there are substantial differences in the extent to which governance mechanisms scale up and achieve impact in different sectors. This paper analyzes how the potential for scaling up a particular governance mechanism is influenced by environmental, market, and social geographies that differ between sectors. Through …

Governing Water Quality Limits In Agricultural Watersheds, Courtney Ryder Hammond Wagner

Graduate College Dissertations and Theses

The diffuse runoff of agricultural nutrients, also called agricultural nonpoint source pollution (NPS), is a widespread threat to freshwater resources. Despite decades of research into the processes of eutrophication and agricultural nutrient management, social, economic, and political barriers have slowed progress towards improving water quality. A critical challenge to managing agricultural NPS pollution is motivating landowners to act against their individual farm production incentives in response to distant ecological impacts. The complexity of governing the social-ecological system requires improved understanding of how policy shapes farmer behavior to improve the state of water quality. This dissertation contributes both theoretically and empirically …
