Barn Owls Exert Top-Down Effects On The Abundance And Behavior Of Rodent Pests, Katherine C. Larson

Cal Poly Humboldt theses and projects

Predators can exert top-down effects on their prey by direct consumption, by imposing risk of predation, or a combination of both. However, empirical evidence for these effects is mixed and inconsistent. Barn owls in agriculture present a system with attributes that should, according to theory, lead to strong top-down effects, but research is limited and the distinction between effects on prey abundance and behavior remains unresolved. Understanding the top-down effect of predators on pests is a cornerstone of integrated pest management and important where barn owls may contribute to the control of rodents on farms. Vegetation can mediate the top-down …

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- …

Emulating Evolutionary Principles For Agriculture: Designing A Biomimetic Vertical Garden By Mimicking Tracheophyte Evolution, Earl M. Riddell

Honors Theses

Biodiversity, particularly in the world’s equatorial regions, is under threat from human industry. Among the most daunting problems facing these biomes is that of the food industry’s continual expansion into what was once rainforest. Expansive monoculture (large cultivated swaths of a single crop species) are the primary threat to tropical biodiversity. This method of agriculture is harmful because it requires the clearing of land that once supported thousands of species in order to replace it with rows of a single crop. If more plants could be grown in a smaller horizontal square footage, farms need not rely so heavily on …

Pronghorn Survival And Resource Selection In Western Nebraska's Agriculturally Dominated Landscape, Katie Piecora

School of Natural Resources: Dissertations, Theses, and Student Research

Nebraska’s pronghorn population has been stable over the last decade, yet their presence on the landscape remains a contentious subject amongst private landowners. Conversion of grassland for crop production and increased anthropogenic activity has drastically altered pronghorn behavior throughout their current range, however basic ecology and resource use by pronghorn in Nebraska remains poorly understood. Establishing baseline population metrics and seasonal patterns of resource use for this population at the eastern periphery of the species range is critical to guide management actions. We deployed GPS collars on 110 adult pronghorn to quantify survival, mortality risk, and seasonal resource selection in …

Sweet And Timely Insurance: The Role Of Honey In Reducing Coffee Producer Food Insecurity Exposure In Mexico, Grant Xavier Storer

Master's Theses

Smallholder coffee producers face a combination of pre- and post-harvest risk factors that leaves them particularly vulnerable to food insecurity. A popular form of on-farm diversification is honey production through beekeeping, that has both nutritional and commercial value. This study investigates the role of honey production as means of food security management due to the heightened pollinating activity during the coffee flowering stage that follows the annual coffee harvest provides an additional non-contemporaneous source of income. Using primary data collected in coffee-producing regions of Chiapas, Mexico, I find that during the honey harvest months, which occurs during the early stage …

Early Life Exposure To Enso And Adult Human Capital, Ashley J. Stewart

21st Century Political Agronomy: Between Collapse And Apocalypse In The Capitalist World System, Harrison Raskin

Honors Scholar Theses

Examinations of the causal chain between ecological impacts and food shortages reveal significant impending global disturbances. This paper draws a causal link between ecological impacts and low food productivity which will lead to food insecurity and economic crises in the near term. Further, this paper argues that food insecurity may lead to the collapse of the capitalist world system. This threat is contrasted with “business as usual” climate models which, rather than depicting the collapse of the capitalist world system, depict its persistence throughout the collapse of the world ecology.

Integrated Agriculture-Aquaculture As An Alternative To Improving Small-Scale Fish Production In Zambia, Oliver J. Hasimuna, Sahya Maulu, Kundananji Nawanzi, Benjamin Lundu, Joseph Mphande, Chisomo J. Phiri, Edwin Kikamba, Enock Siankwilimba, Sillah Siavwapa, Moses Chibesa

School of Biological and Marine Sciences

Aquaculture is a significant industry in food production, and its contribution to food and nutrition security is well acknowledged. Zambia’s aquaculture production has continued to increase significantly, thus playing a key role in supplying animal protein sources for human consumption. However, recent estimates show that 75% of the national aquaculture production comes from large-scale commercial producers despite being by far the minority while the majority of small-scale producers contribute the remaining 25% of the total annual production. This low production by small-scale producers is attributed to insufficient financial resources, poor management and utilization of farm resources, lack of access to …

Application Of A High-Resolution Climate Model Dataset To Assess Habitat Suitability For Spotted Wing Drosophila In Southwest Idaho, Elizabeth Padian

Boise State University Theses and Dissertations

As global climate change continues to produce large deviations from the normals of the 19th and 20th centuries, the agricultural sector will need to adapt to these changes in order to maintain yields and feed the global population. Crop selections, yield amounts, and pest management techniques may need to be adjusted to adapt. The Spotted Wing Drosophila (SWD) is a small fruit fly-like bug that can infest berries and stone fruit crops by burrowing into the fruit (at most points in the fruit’s lifecycle) and laying its eggs. These eggs will hatch and the larvae will burrow back out of …

Ireland V. United States: Agricultural And Environmental Sustainability Policies, Lauryn O'Grady

Accounting Undergraduate Honors Theses

The United States and Ireland have varying practices to achieve similar objectives in regard to environmental sustainability. While the European Union has maintained and updated a uniform policy throughout its existence--the Common Agricultural Policy--the United States instead created short-term solutions to a long-term problem. Not only does the United States tend to solve issues in the short-term, the policies between agricultural production and environmental sustainability are not necessarily aligned or remotely relative to the other. While the United States’ new Global Food Security Strategy implements parts of both agricultural and environmental sustainability, much of the history was not based off …

Agricultural Literacy And Food Production In Nigeria, Tor-Akwer Helen Famaren, Dominic Aondohemba Ihongo, Comfort Member Tyopev

Library Philosophy and Practice (e-journal)

There are growing concerns relating to current Nigerian agricultural food production practices and its impact on human nutrition. There is mounting evince that our current food system is responsible for diseases such as diabetes and obesity. Agricultural literacy is possessing knowledge and understanding of our food and fiber system. For citizens to be minimally educated about agricultural practices, agricultural literacy is important for both the individual and for the industries. An individual must be well informed to make responsible choices in matters of food and fiber. Improving agricultural literacy by understanding the needs of the society, as it relates to …

Reviving The Roots: A Qualitative Phenomenological Study Of Black Women In Agriculture And The Influence Of Post-Secondary Education, Alvianna Woodard-Davis

Doctoral Dissertations and Projects

The purpose of this qualitative phenomenological study was to explore the perceptions and lived experiences of twenty Black women in the southern United States and the influence of post-secondary education on agricultural science. Two theories guided this study, Maslow's hierarchy of needs and Crenshaw’s intersectionality theory. When considering the five levels of Maslow's hierarchy, coupled with Black women's marginality as identified by the intersectionality theory, the research helped better define the relationship between Black women in agriculture and the referenced theories. Criterion sampling was used to identify ten experienced Black female producers and ten agriculture students to determine the trend. …

Agriculture: A Feminist Commodity Chain Analysis, Shriraksha Mohan

Student Papers in Local and Global Regional Economies

Feminist Commodity Chain analysis enables economists to situate women within the framework of the global commodity chains, and recognize their roles in creating values in various stages of the commodity chain. Unlike in the “realist” commodity chain, when feminist commodity chain concepts are applied to agriculture, there is emphasis on women as the agents in various nodes of agriculture commodity chain, from the beginning of farming, with sowing of seeds, to the end as consumers of agricultural products. This approach allows researchers to understand how gender ideologies shape the social and structural hierarchies within commodity chains, and account for how …

The Effect Of Rhizophagus Intraradices Mycorrhizal Fungus On Iron Uptake Of Corn: A Global Overview On The Effects Of Climate Change On The Nutritional Content Of Crops, Caitlin R. Costello

PSU McNair Scholars Online Journal

Global iron deficiency is a major factor contributing to malnutrition and varied health conditions. One way to combat this is to maintain or increase the iron uptake of the globe’s major crops. Research has shown that certain types of mycorrhizal fungi can increase the nutrient uptake of plants. To further this research, we looked at the arbuscular fungi Rhizophagus intraradices and its potential relationship with the corn variety “Golden Bantam 8 Row”. This type of mycorrhizal fungi improves plant nutrition including the plant’s ability to source iron from the natural environment. Much of the iron found in the natural environment …

Food, Freedom, Fairness, And The Family Farm, Robin Rotman, Sophie Mendelson

West Virginia Law Review

The concept of the “family farm” holds powerful sway within the American narrative, embodying both nostalgia for an imagined past and anxiety for a future perceived to be under threat. Since the founding of the United States, this cultural ideal has been invoked in support of a rosy vision of agrarian democracy while obscuring the ways in which the U.S. Department of Agriculture’s codified definition of “family farm” has unfairly aggregated advantages for the benefit of a particular kind of family (nuclear) and farmer (white, male, straight). At the same time, consumers are misled by an under-interrogated conflation of family …
