Analyzing Youth Engagement And Gender Roles In The Groundnut Value Chain In Uganda Using The Photovoice Research Methodology, Annie Faye Carter
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 …
Assessing The Impact Of Parental Involvement On The Scaling Of Agricultural Technologies From School Garden To Home Farm Through Experiential Learning, Gracie Pekarcik
Assessing The Impact Of Parental Involvement On The Scaling Of Agricultural Technologies From School Garden To Home Farm Through Experiential Learning, Gracie Pekarcik
Masters Theses
Cambodia is a predominantly rural nation with a heavy dependence on agriculture, particularly smallholder rice farming systems. While several sustainable agricultural technologies have been successfully piloted on research stations or with small numbers of early adopters, questions remain on how to extend these technologies to large numbers of resource-poor smallholders. The Scaling Suitable Sustainable Technologies Project (S3-Cambodia) seeks to examine pathways for scaling sustainable intensification (SI) technologies to smallholder farmers. One of the identified pathways to scaling SI is through the education system. Cambodian youth serve as an entry point to extend target technologies to farm families through experiential learning …
Songbird-Mediated Insect Pest Control In Low Intensity New England Agriculture, Samuel J. Mayne
Songbird-Mediated Insect Pest Control In Low Intensity New England Agriculture, Samuel J. Mayne
Masters Theses
Global agricultural intensification has caused large-scale wildlife declines, but agricultural lands that maintain natural habitats can support healthy wildlife populations and receive significant ecosystem services from these natural communities. However, how on-farm biodiversity results in beneficial ecosystem services is highly variable and is reported to differ among taxa and guilds. One group that has attracted attention for their potential beneficial role in reducing pest abundance are birds. Understanding the role of bird communities and individual species in pest control could be important for managing farms under a low intensity agroecological framework. In New England, farmers are increasingly applying low intensity …
Strong Women Breaking Ground: Roles Of Women In Agriculture In Michigan, April L. Shirey
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 …
Effects Of Am Fungi From Conventional And No-Till Michigan Crop Fields On Plant And Soil Health, Derek Bennett
Effects Of Am Fungi From Conventional And No-Till Michigan Crop Fields On Plant And Soil Health, Derek Bennett
Masters Theses
Centuries of conventional till (CT) management in agriculture has depleted soil organic matter (SOM) by over 50%. While only comprising 5% in most soils, SOM provides soil with fertility and productivity. To compensate for SOM depletion, producers have been forced to increase their reliance on fertilizer and irrigation to maintain yields. In the coming decades, climate change is expected to challenge food production and threaten an already fragile system. With no remaining land left to cultivate, conservation management strategies such as no-till (NT) look to restore SOM and increase the resilience of food production for an ever growing, increasingly food …
Spatiotemporal Observations Of Water Stress In Kansas Winter Wheat And Corn From Remotely Sensed Evapotranspiration And Ndwi, Lindi Diane Oyler
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 …
Phosphorus Retention In West Michigan Two-Stage Agricultural Ditches, Emily Kindervater
Phosphorus Retention In West Michigan Two-Stage Agricultural Ditches, Emily Kindervater
Masters Theses
Input of excess nutrients into a water body can negatively impact ecological structure and function, as well as the economic vitality of surrounding communities, by contributing to eutrophication. For example, phosphorus (P) and sediment inputs from agricultural drainage have facilitated the development of hypereutrophic conditions in Lake Macatawa, a drowned river mouth lake located in Holland, Michigan. Two-stage ditches, an agricultural best management practice (BMP), are used in some areas of the Midwest to reduce N export downstream via denitrification. This BMP simulates a mini-floodplain by replacing a traditional, trapezoidal ditch with a channel that has excavated benches on each …
Long-Term Impacts Of Conservation Management Practices On Soil Carbon Storage, Stability, And Utilization Under Cotton Production In West Tennessee, Candace Brooke Wilson
Long-Term Impacts Of Conservation Management Practices On Soil Carbon Storage, Stability, And Utilization Under Cotton Production In West Tennessee, Candace Brooke Wilson
Masters Theses
Biogeochemical cycling of soil carbon (C) is heavily influenced by conservation agricultural (CA) practices. This study examined SOC stability under three CA practices: reduced nitrogen (N) fertilizer application rate, cover cropping, and zero-tillage implemented for 31 years. Respiration rates measured from a 602-day incubation period were fitted to a double-pool first order exponential model of SOC decomposition. The active [respired] SOC pool showed distinct differences between applications of reduced (34N kg ha-1 [-1]) and high fertilization rates (101N kg ha-1) combined with tillage, and suggest that high fertilizer applications with conventional tillage allocated more C into a …
Generating Best Management Practices For Avian Conservation In A Land-Sparing Agriculture System, And The Habitat-Specific Survival Of A Priority Migrant, Jeffrey D. Ritterson
Generating Best Management Practices For Avian Conservation In A Land-Sparing Agriculture System, And The Habitat-Specific Survival Of A Priority Migrant, Jeffrey D. Ritterson
Masters Theses
A large amount of the world’s biodiversity is located in a disproportionately small amount of area, namely the tropics. Many of these areas are experiencing rapid landscape changes, mainly in the form of deforestation for agricultural practices. Current conservation efforts are focused on agricultural areas and their ability to provide habitat. The conservation value of a novel land-sparing agroforestry system, known as Integrated Open Canopy (IOC), was recently demonstrated on the study site when applied to coffee. IOC coffee supports forest species that are uncommon or absent in shade grown coffee. I generated best management practices for IOC farms relative …
