Reintroducing Hemp (Rongony) In The Material Palette Of Madagascar: A Study On The Potential Of Hemp Clay Components And Its Impact On Social And Ecological Communities., Henintsoa Thierry Andrianambinina

Masters Theses

When mentioning the word hemp, especially in the local language of Madagascar, the literal translation does not set it apart from marijuana, as they are both called “rongony” - creating the stigma around hemp as the negative stereotype of marijuana. However, the material has been used by the ancestors of Madagascar, as well as across cultures, in its fibrous form to produce fabrication like textile goods and packaging. During colonization, the prohibition of hemp intensified, and since then, any activity related to either of these plants is prohibited and will end in severe punitive measures. This thesis explores the strengths …

Analyzing Youth Engagement And Gender Roles In The Groundnut Value Chain In Uganda Using The Photovoice Research Methodology, Annie Faye Carter

Masters Theses

In regions of East Africa, groundnut (Arachis hypogaea L.) is cultivated as a common cash crop in areas of food insecurity and agricultural-dependent communities. Groundnut, also known as peanut, is a legume with a variety of important uses. This crop is especially popular with small-scale farmers and youth, who seek to harvest a crop which is affordable. As an expected 440 million young people enter the global labor market by 2030, those living in rural areas are at a disadvantage when searching for job opportunities. In Africa, this rural-urban divide has impacted the economic sector and the activities …

Impact Of Far-Red Light Supplementation On Yield And Growth Of Cannabis Sativa, Thomas Benjamin Carter

Masters Theses

Far-red light(700-780nm) induces shade avoidance response in many different species of plants. The shade avoidance response triggers a number of changes in the plant such as cell expansion and stem elongation. This cell expansion has shown to increase yields in leafy greens and increase flower set in tomatoes. Despite there being a void in the literature for Cannabis sativa, far-red lights are often advertised to provide several benefits. This study will evaluate the effects of far-red light supplementation on the yield and height of Cannabis sativa. Five cannabis clones were grown under white (410-730nm) light emitting diodes (LED’s) at …

Food Security Through Disaster Planning In Tanzania: How Agriculture-Based Disaster Preparedness Can Improve Food Security In Tanzania, Savannah A. Emerich

Masters Theses

In Tanzania, half the population lives below the poverty line and suffers from food insecurity. Of the population, women and children primarily suffer from malnutrition due to food insecurity. For Tanzania, the problem is so severe that some women do not name their newborns for weeks or months due to their unlikely survival. This problem worsens for those who have a significant reliance on agriculture and live in the nation’s rural areas. These rural communities face more traumatic burdens when floods and droughts destroy crops, fields, and tools and ruin livelihoods. A solution has not been implemented thus far due …

Strong Women Breaking Ground: Roles Of Women In Agriculture In Michigan, April L. Shirey

Masters Theses

Agriculture in Michigan is changing. While the number of farms and farmers continue to decrease, women are increasingly taking on the role of farmer instead of the “farmer’s wife”. The number of female producers increased from 8,275 to 26,059 where the number of producers in Michigan decreased from 56,014 to 47,641 from 2007 to 2017 (USDA, 2007, 2017). Women are becoming the face of farming in Michigan, yet little research examines the impacts of these shifts. In this research, I conduct semi-structured interviews with female farmers throughout lower Michigan beginning in the summer of 2020 to learn more about these …

Spatiotemporal Observations Of Water Stress In Kansas Winter Wheat And Corn From Remotely Sensed Evapotranspiration And Ndwi, Lindi Diane Oyler

Masters Theses

"Optimizing water use is a growing concern, especially in agricultural communities where water use is high. An important challenge in agricultural water optimization is knowing when and where crop water stress is occurring, particularly on large scales where in-situ measurements are no longer practical to obtain. In an effort to combat this challenge, this study utilizes remotely sensed evapotranspiration (ET) and Normalized Difference Water Index (NDWI) to evaluate the responses of integrated satellite datasets to water-stressed conditions over fields of irrigated corn, irrigated winter wheat, and rainfed winter wheat from 2007 to 2017 in southwestern Kansas. Using two different ET …

Agritourism Development In Southwest Michigan: Motivations Of Agritourists And Operators, Esther Akoto Amoako

Masters Theses

National agricultural statistics show that the number of agritourism farms and the proportion of agritourism related revenues in the United States has steadily increased during the last ten years, especially among small family farms. The recent growth in agritourism is both demand - and supply-driven. However, there are limited studies that explore agritourism motivations from both the visitors' and operators’ perspectives. This study examines what the agritourists' and operators’ motivations are and the challenges facing the industry to provide information for those currently involved and those wanting to include agritourism in their operations. Online and in-person surveys and unstructured interviews …

Spatial And Temporal Heterogeneity Of Carbon Storage And Optimal Provision Of Carbon Storage, Amine Mohamed Ben Ayara

Masters Theses

Human activity, particularly the conversion of natural land cover into human-dominated cover types, is putting increasing pressure on the health of the global ecosystem. Loss of forestland is a major contributor to greenhouse gas (GHG) emissions, which cause climate change because forests can help sequester GHG emission in the atmosphere. However, mitigating climate change by sequestering carbon through reforestation and/or avoiding deforestation is an appealing option because of the potential scale of such sequestration, the possible cost advantages over other mitigation efforts, and the opportunity it provides to incentivize the sustainable use of rural lands. Incentive payments can support forest-based …

4-H Wildlife Habitat Education Program: A Qualitative Study On Career Exploration, Ronnie Lee Cowan

Masters Theses

There are documented studies on the Wildlife Habitat Education Program (WHEP) that relate to building life skills of participants. However, no literature was found that measured the perceptions of the participants towards a career in wildlife after participating in WHEP. To add validity to the program a focus group was conducted at the Tennessee 4-H wildlife judging contest to describe the WHEP participants’ perceptions of careers in wildlife after the completion of the annual program. Focus group participants indicated that participating in WHEP peaked their interest in wildlife and provided an opportunity to experience the importance of natural resource management.

Economic And Environmental Optimization In The Supply Of Switchgrass In Tennessee, Jia Zhong

Masters Theses

The low efficiency of collection, storage and transportation in the switchgrass supply chain has hindered the commercialization of a switchgrass-based biofuel industry, even given its ecological and environmental advantages in carbon sequestrate, soil quality, water use, and pollution pressure. Thus, designing a switchgrass-based supply chain balancing both environmental and economic performance is important to expedite the development of the cellulosic biofuel industry to meet the national energy plan.

The objectives of this study are to 1) determine economic cost and multiple environmental outcomes in feedstock supply chains and 2) identify the relation between the economic and environmental performances. The first …

Data Storage Alternatives For A Gridded Crop Disease Risk Forecasting System, Paul J. Roehsner

Masters Theses

Three separate storage technologies able to serve gridded data were selected for comparison of performance in terms of providing speed and expandability to a crop disease forecasting system. The three storage technologies chosen were PostgreSQL (a relational database management system), MongoDB (NoSQL system), and netCDF files. Speed tests were performed for each by running two different crop disease risk forecasting models requiring data of different spatiotemporal resolutions. Multiple trials were done using different storage hardware. Systems were then qualitatively compared for expandability by noting the process involved in adding successive crop disease forecasting models.

It was found that due to …

Intensity Of Adoption Of Direct Marketing Strategies Among Fruit And Vegetable Farmers In Tennessee, Carey Ann Wolanin

Masters Theses

Consumer interest in fresher foods has increased over the past few years and has stimulated the growth of direct-to-consumer outlets. Tennessee currently hosts many types of direct food outlets, including farmer markets, CSAs, roadside stands, and pick-your-own operations. Using data from a 2011 survey of Tennessee fruit and vegetable producers, factors associated with the percentage of sales fruit and vegetable producers make through direct-to-consumer outlets or intensity of adoption of direct-to-consumer marketing strategies are evaluated using fractional logit and logit regressions. Findings suggest that the percentage of sales a producer makes through direct-to-consumer outlets is associated with farmer age, the …

Factors Influencing Precision Farming Technology Adoption Over Time In Southern U.S. Cotton Production, Pattarawan Watcharaanantapong

The Suburban Rice Farmers: Economic And Cultural Change In Japan, Makoto Chiwaki

Masters Theses

The world economic situation is forcing the Japanese government to initiate policies designed to make its rice farming industry more competitive on the world market. These new policies, along with the growth of Japan's urban areas, are causing certain stresses on the cultural institution called bunke among the part-time rice farmers in the Kaizuka region of Chiba City, Japan.

An ethnographic study of these farmers reveals that the farmers of the Kaizuka region have responded to recent changes differently from the farmers of other regions because of their cultural institutions and traditions.
