Breaking The Loop: Strategies For Fighting Climate Change On U.S. Farms, Ashley Barry
Honors Capstones
Climate change is an increasingly urgent area of research due to the hardships it causes for lands and communities across the globe. Specifically in regard to the United States (U.S.), climate change has many concerning implications on our agricultural system. Increased weather hazards, decreased crop production, and drought are just a few of the hardships American farmers are facing in their fight to keep their farms alive and feed their communities, despite a rapidly changing climate. This study investigates how farmers can fight and prevent climate change through the use of specific mitigation and adaptation strategies on their farms. Semi- …
The Influence Of Framing And Recent Experience On Farmer Choices In Experimental Games Depicting Risk-Reducing Agricultural Technologies, Ana Maria Ospina Tobar
The Influence Of Framing And Recent Experience On Farmer Choices In Experimental Games Depicting Risk-Reducing Agricultural Technologies, Ana Maria Ospina Tobar
Electronic Theses and Dissertations
Climate change is a major threat to food security, particularly in low and middle-income countries that are highly dependent on staple crops for subsistence. The vulnerability of staple crops, like maize, in the face of climate change, is increasing due to the increasing frequency of droughts. This thesis aims to evaluate two mechanisms through which farmers may be more willing to adopt new technologies that increase their resilience to climate change: First, I evaluate the effectiveness of a new virtual maize farming game as a learning tool to teach farmers about the outcomes they could obtain under different weather events …
Assessment Of Historical Climate Variability In Maine With Implications For Future Agricultural Productivity And Adaptation, Carly Frank
Electronic Theses and Dissertations
Climate change is a wicked problem with global impacts, one of which being the sustainability of the existing global food system. As temperatures and variability in precipitation are projected to increase, the challenges to agriculture are expected to intensify. This thesis examines the Maine historical climate record over the growing season, in combination with future projections, to assess how conditions have changed and will change with agricultural implications. In this analysis, relevant climatic variables are analyzed, and agriculture-significant measures are derived for Maine’s three climate divisions using four decades of daily and monthly gridded datasets. In addition, this thesis explores …

The situation manifests in terms of low productivity, low production level, and poor income to the farmers. The purpose of this qualitative study was to investigate the experiences and perceptions of the cassava farmers on cassava policies and the effect on their income and livelihoods in the Ikorodu local government of Lagos State. This qualitative study adopted a case study research design using participatory …
Assessing Impacts Of Winter-Hay Feeding On Soil And Forage Nutrient Dynamics In A Rotationally-Grazed Pasture System In Arkansas, Lawrence Gordon Berry Iv
Assessing Impacts Of Winter-Hay Feeding On Soil And Forage Nutrient Dynamics In A Rotationally-Grazed Pasture System In Arkansas, Lawrence Gordon Berry Iv
Graduate Theses and Dissertations
More than 38 % of United States’ rural land area was used for grazing (i.e., pastureland or rangeland) ruminant animals in 2017, constituting the largest private land use group. The expansive nature of these lands means that grazing and pasture management decisions have potential to impact water quality as well as profit margins. As a result, beef producers are under increased pressure from economic and environmental standpoints to limit application of nutrients beyond those required to grow the forage needed for animal consumption. At the same time, a large amount of nutrients is recycled back to pasture systems directly from …
Estimation Of Spatial Change In Cropland Area And Evaluation Of Irrigation Performance In Imperial Valley Using Remotely Sensed Data, Usha Poudel
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Imperial Valley (IV) in the US is an extensively irrigated agricultural region, which includes multiple crops changing on an annual and semiannual basis. The valley is facing grave concerns about water management due to its semi-arid environment, water intensive crops, and limited water supply. A simple, inexpensive, and repeatable method to detect changes in cropping patterns may assist irrigation managers to understand crop diversification and associated consumptive use. In addition, a spatial assessment of existing water irrigation system performance and productivity is crucial to benchmark and improve current water management strategies. This thesis estimates the spatial pattern of change …

Theses and Dissertations
This paper will explore the Burkinabé revolution and the governmental structure which formed out if it, as an ideological entity with some governing capabilities but not simply a political body as it did not possess the capacities at any time to fully govern the country in terms of the implementation of intended social and economic programs. However, these programs were extremely widespread encompassed swaths of rural society in ways that it had not since the Mossi Empire became centralized and rose to regional prominence in the 18th century. The ideological identity of the revolution in Burkina Faso was not a …

Governing Water Quality Limits In Agricultural Watersheds, Courtney Ryder Hammond Wagner
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 …
The Power Law Distribution Of Agricultural Land Size, Lauren Chamberlain
The Power Law Distribution Of Agricultural Land Size, Lauren Chamberlain
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This paper demonstrates that the distribution of county level agricultural land size in the United States is best described by a power-law distribution, a distribution that displays extremely heavy tails. This indicates that the majority of farmland exists in the upper tail. Our analysis indicates that the top 5% of agricultural counties account for about 25% of agricultural land between 1997-2012. The power-law distribution of farm size has important implications for the design of more efficient regional and national agricultural policies as counties close to the mean account for little of the cumulative distribution of total agricultural land. This has …
Understanding The Food Water Nexus: Characterizing The Impact Of Climatological Anomalies On Agrosystems, Patrick M. Wurster Jr.
Understanding The Food Water Nexus: Characterizing The Impact Of Climatological Anomalies On Agrosystems, Patrick M. Wurster Jr.
Graduate Student Theses, Dissertations, & Professional Papers
Climate variability at global and regional scales is escalating with increased atmospheric carbon and is expected to magnify the intensity and duration of meteorological extremes, especially droughts. From the many environmental stresses that diminish crop production (e.g., soil salinity, frost, soil erosion) drought is one of the most prevalent. This study focuses on the sensitivity of three key crops produced in the northwestern United States to climatological anomalies, while controlling for attribution using anomalies in price. The study differs from similar studies in that we focus on variability in production which captures both yield (tonnes/ha) and cropping area (ha), as …
Attracting Beneficial Insects To Your Farm: A Comparison Of Habitat Modification Strategies, Kelly Rourke
Attracting Beneficial Insects To Your Farm: A Comparison Of Habitat Modification Strategies, Kelly Rourke
Master's Projects and Capstones
Thoughtful planning to enhance diversity in agricultural landscapes can present a multitude of ecological, cultural and economic benefits. Land managers have many options when considering which habitat modification techniques they can implement on their agri-environment schemes. This comparative analysis of 47 peer reviewed journal articles assesses which landscape enhancements are most effective in attracting beneficial insects, namely pollinators and natural enemies to pests. Through biological control, natural invertebrate predators inhibit vegetative pests that can be detrimental to croplands. The promotion of natural enemies can decrease the need for chemical use and maintenance on farms. Pollinators contribute tremendous benefits to crop …
Financial Assessment Of Agricultural Lands At Risk To Coastal Salt Marsh Migration In Relation To Climate Change Induced Sea Level Rise In Dorchester County, Maryland, Jewell Porter
International Development, Community and Environment (IDCE)
The increasing rate and effects of sea level rise is a major environmental concern in the Chesapeake Bay. This paper evaluates the impacts of rising sea level on coastal salt marshes and the surrounding agricultural lands at risk in Dorchester County, Maryland to build off existing environmental monitoring work performed by NOAA’s Sentinel Site Program. The results of the spatial analysis were used to estimate monetary benefits to incentivize farmers to protect these marshes by making their land available for marsh migration to occur. Looking at three scenarios of sea level rise and marsh migration, grain crops (corn, soybeans, and …
Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras
Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras
Electronic Thesis and Dissertation Repository
The repeated occurrence of Lake Erie’s harmful algal blooms suggests an inadequate phosphorus management system that results in excessive loads to the lake. In response, Canadian and United States’ governments have issued a new management objective, a 40% reduction in total and dissolved reactive phosphorus loads relative to 2008. To provide scientific evidence to guide managers toward achieving their management objective, we used the International Organization of Standardization (ISO) 31010 Bowtie Risk Analysis Tool to analyze the performance of the phosphorus management system. The effectiveness of agricultural best management practices (BMPs) and their adoption were combined into a Bayesian belief …

I review the existing urban agriculture policies Chula Vista has and compare them to other cities in California. The second part of the project is concerned with how to choose and develop a site for …
The Golden Pandemic, Leo Dylan Stevens-Lubin
The Golden Pandemic, Leo Dylan Stevens-Lubin
Senior Projects Spring 2016
The work in my senior show is a representation on how I feel about conventional focusing specifically on corn. The reason that I have chosen corn is because it is one of the most detrimental crops that we are growing in the US. It is grown specifically for livestock feed and ethanol with a minimal fraction for direct human consumption. Corn itself offers minimal nutritional benefits in comparison to most other vegetable crops and the overproduction of corn crops decreases the benefits all the more.

Landscape Ecological Analysis Of Patterns Influencing Bat Activity In Southeast Glacial Plains Of Wisconsin, Angela Leckie Jackson
Landscape Ecological Analysis Of Patterns Influencing Bat Activity In Southeast Glacial Plains Of Wisconsin, Angela Leckie Jackson
Theses and Dissertations
Nearly half of the world's bat species are threatened by anthropogenic land use. To contribute to the conservation of these cryptic mammals, it is imperative to understand bat habitat selection in human-dominated landscapes. Bat activity was calculated using active acoustic surveys conducted June and July for three years along river and lake transects in an agricultural matrix. Using multiple logistic regression and ANOVA regression tree analyses, I examined the relationship between bat activity of four species and habitat structure at multiple scales.
Aquatic features were determined to be the greatest predictor of bat activity with rivers supporting greater amount of …
Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh
Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh
Pomona Senior Theses
This thesis uses an efficiency analysis of agricultural systems to assert that, in lieu of rising prices of fossil fuel, people need to come into more direct contact with their food systems. With a switch to smaller, more efficient farms that rely less on fossil fuel and are connected with the communities they supply for, we can avoid an energy crisis turning into a famine. These smaller-scale systems can help create self-contained, carbon-neutral communities.
A Landscape Approach To Late Prehistoric Settlement And Subsistence Patterns In The Mojave Sink, Tiffany Ann Thomas
A Landscape Approach To Late Prehistoric Settlement And Subsistence Patterns In The Mojave Sink, Tiffany Ann Thomas
UNLV Theses, Dissertations, Professional Papers, and Capstones
The environment of the Late Prehistoric period (1200 A.D. to Historic Contact) Mojave Sink was wetter than modern conditions. The settlement and subsistence patterns of the occupants of the region during this period were driven by the availability of water, subsistence resources, raw material sources, and tradition. These people utilized the regional landscape based upon the seasonal availability of these resources. Supplemental agricultural production has been proposed for the Mojave River Delta due to the more favorable environmental conditions of this period. If agriculture was being practiced it would have affected the regional land-use patterns. For this thesis I propose …
Go Farm, Goleta: Urban Agriculture Protection For Eastern Goleta Valley, Eli M. Krispi
Go Farm, Goleta: Urban Agriculture Protection For Eastern Goleta Valley, Eli M. Krispi
Master's Theses
This paper explores two potential land use planning strategies that can be used to preserve and enhance the economic viability of agricultural operations surrounded by suburban development in Santa Barbara County’s Eastern Goleta Valley: buffers between agriculture and other land uses, and agritourism. In the case of buffers, academic literature is examined to determine how effective buffers are at various tasks (filtering runoff, mitigating dust and wind, providing habitat, etc.) and how to construct buffers to maximize their effectiveness. Land use plans and codes from several California jurisdictions are studied to see how buffers are put to use. Academic literature …
Farmers Motivations To Practice Sustainable Agriculture, Kimberly A. Floeser
Farmers Motivations To Practice Sustainable Agriculture, Kimberly A. Floeser
Honors Theses
An increasing awareness of human and environmental health issues and the destruction of family farms and rural communities have caused a significant change in the way many farmers, consumers, and policy‐makers are thinking about and relating to food, the results of which can be seen largely in the growth of the organic and sustainable food industry. This paper attempts to examine and explain farmers’ attitudes towards sustainable agriculture, and their motivations to use sustainable methods of production. A survey was distributed to 533 farms that are members of the Northeast Organic Food Association of New York (NOFA‐NY). The data obtained …
Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott
Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott
CMC Senior Theses
For several decades following its independence from Great Britain, Ghana’s policies continued to promote over-extraction of natural resources to the detriment of its economy and rural communities. Agricultural and forestry policy has gradually evolved to foster more sustainable and equitable practices, as in building partnerships with the private sector to fund infrastructure improvements. Policy has recently recognized the dire need to adopt agricultural practices and means of forest resource extraction that are compatible with ecological stewardship. However, many shortcomings are still apparent. Large logging operations completely disregard forestry regulations with impunity, whereas rural sustenance extractors are severely punished in the …
Random Forests Applied As A Soil Spatial Predictive Model In Arid Utah, Alexander Knell Stum
Random Forests Applied As A Soil Spatial Predictive Model In Arid Utah, Alexander Knell Stum
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Initial soil surveys are incomplete for large tracts of public land in the western USA. Digital soil mapping offers a quantitative approach as an alternative to traditional soil mapping. I sought to predict soil classes across an arid to semiarid watershed of western Utah by applying random forests (RF) and using environmental covariates derived from Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and digital elevation models (DEM). Random forests are similar to classification and regression trees (CART). However, RF is doubly random. Many (e.g., 500) weak trees are grown (trained) independently because each tree is trained with a new randomly …
