An Economic And Production Analysis Of Seaweed Farms In California And The Pacific Northwest, Brian Donovan

Cal Poly Humboldt theses and projects

Since the early 2010s, the seaweed aquaculture industry has steadily expanded in the United States, with states like Alaska, Maine, Hawaii, and Connecticut leading the way in the development of this emerging sector. However, information gaps remain concerning certain aspects of the domestic seaweed aquaculture industry. The purpose of this study was to examine the status of the seaweed aquaculture industry along the West Coast of the United States; specifically in the states of California, Oregon, and Washington. Seaweed farmers in these states were invited to voluntarily complete surveys asking important production, economic, and commercial questions regarding their operations. Data …

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

The Effectiveness Of The Minnesota Buffer Law And Its Impacts On People, Ellen P. Isakson

Journal of Earth and Life Science

In January 2015, the then-governor of Minnesota Mark Dayton announced new legislation that would require 50-foot vegetation buffers along all waterways in Minnesota; this legislation would come to be known as the Minnesota buffer law, exact requirements being “perennial vegetative buffers of up to 50 feet along lakes, rivers, and streams and buffers of 16.5 feet along ditches” (Albert, 2017; MN Board of Water and Soil Resources [MN BWSR] 4 ). A buffer in the context of vegetation and natural resource management is a strip of vegetation around a body of water “designed to intercept stormwater runoff and minimize soil …

A Study Of Collegiate Equine Team Funding, Expenditures, And Recruitment Strategies, Sydni Marie Nilles

Graduate Theses/Dissertations

Collegiate equine teams (including horse judging, equestrian, ranch horse teams) have been recognized for their contributions to students' personal and professional development for post- graduation success. Teams have been used to provide opportunities, a sense of belonging and allow for experiences students may not have elsewhere. However, there is a notable gap in knowledge as to where funding comes from and how much teams may be able to budget for expenditures. Recruitment tactical knowledge provides other teams with knowledge of potential areas they may be lacking or unaware of. I used an online survey to understand current ranges of support …

Next In Line: Exploring Owner, Business, And Family Characteristics And Farm Succession Planning, Tucker Lane Bittick

Graduate Theses/Dissertations

The growing average age of the American farmer raises concerns about who will be involved in the future agricultural economy. Efficient succession in family farms keeps farm values high, and farms that plan for succession have an incentive to invest more resources into the farm. Knowing what factors on family farms are common when succession occurs could help encourage earlier succession planning. The research questions were: “Are family, business, and owner characteristics significantly related to the presence of a farm succession plan on farms in the Midwest?” and “Are family, business, and owner characteristics significantly related to principal operators’ preference …

Cost-Effective Strategies For Feral Swine Control: Exploring Trapping Equipment Cooperatives, Phil Kenkel, Riza Radmehr, Rodney Holcomb, Mckenzie Boyce

Human–Wildlife Interactions

Feral swine (Sus scrofa) in the United States have become a growing concern, with a population of ≥6 million and causing annual damages of ≥$1.5 billion USD. Because of their high reproductive capacity, effective control methods are crucial to reducing or slowing their population growth. While remotely monitored and triggered traps have proven to be an effective control strategy, the cost of sophisticated trapping equipment, which can cost ≥$7,000 USD, is often cost prohibitive for many landowners. Despite the pressing need to address the challenge of making effective feral swine control methods more affordable, there are few studies …

Estimating The Carbon Footprint Of Sheep Production In Western Australia, Tafesse Estifanos, Christophe D'Abbadie, Johnny Machon, Amir Abadi Abadi Ghadim, Gus Manatsa, Paul Mattingley, Ross Kingwell, Kevin Foster

Farm Systems and Economics published reports

Western Australia’s broadacre mixed farming systems combine cropping and sheep production and are the largest component of the state’s agricultural sector. The south west Western Australia (WA) agricultural area hosts about 98% of the state's sheep flock. The sheep industry contributed $1.5 billion to the state’s economy in 2021-22 and accounts for about a quarter of on-farm greenhouse gas (GHG) emissions. Most sheep industry emissions (over 80%) come from methane produced by the sheep. Despite this environmental impact, only 9.9% of Australian sheep producers have estimated their emissions, which limits the industry's ability to monitor and manage carbon footprints effectively. …

Aflatoxin Prevalence And Association With Maize Grain Physical And Nutritional Qualities In The Informal Markets In Meru County, Kenya, C. Cherotich, M. W. Okoth, Abong’ Go, S. W. Kariuki, E. R. Omuse

All Peer-Reviewed Publications

In Kenya, aflatoxin contamination in maize remains a persistent issue, with potential negative impacts on both public health and economic growth. Aflatoxins are toxic secondary metabolites produced by certain mold species, primarily Aspergillus flavus. The extent of Aspergillus fungal invasion in maize grains and the resulting increase in aflatoxin levels is heavily influenced by pre-and post-harvest practices. Before harvest, factors such as insect damage and exposure to warm, humid conditions increase the crop's susceptibility to Aspergillus infection and subsequent aflatoxin formation. Post-harvest, additional risks arise when kernels are damaged by pests like rats or when they are stored in unfavorable …

Suas Agricultural Aerial Application Operational Field Test, David Thirtyacre, Joseph Cerreta, Scott S. Burgess

International Journal of Aviation, Aeronautics, and Aerospace

One of the most promising uses of aerial applications by a sUAS is on small farms where traditional crewed aerial applicators were not practical due to the limited size of the operations. This controlled field test aimed to assess the feasibility and cost-effectiveness of using a sUAS spreading system compared to the traditional manual application of weed killer and fertilizer on cranberry bogs in Western Washington that were less than 10 acres. The aerial application took place over two separate days as scheduled by the farmer for maximum product efficiency. A total of sixty-three flights were necessary to apply the …

An Assessment Of Vegetable Production Constraints, Trait Preferences And Willingness To Adopt Sustainable Intensification Options In Kenya And Uganda, Rose N. Okoma, Evanson R. Omuse, Daniel M. Mutyambai, Dennis Beesigamukama, Marius F. Murongo, Sevgan Subramanian, Frank Chidawanyika

All Peer-Reviewed Publications

Global food production systems are under pressure due to population increase, limited farmland, biotic and abiotic constrains, and ongoing climate change. Sustainable intensification is needed to increase agricultural productivity with minimal adverse environmental and social impacts. Vegetable-integrated push pull (VIPP) technology coupled with black soldier fly (BSF) frass offer such opportunities to smallholder farmers. However, farmers’ vegetable preferences and willingness to adopt these innovations remain unknown and are variable across various geographic scales. Focus group discussions (FGDs) and in-person interviews with smallholder farmers were conducted to assess vegetable production constraints and select vegetables to be integrated into VIPP coupled with …

Consumer Preferences For Low-Methane Beef: The Impact Of Pre-Purchase Information, Point-Of-Purchase Labels, And Increasing Prices, Kelly A. Davidson, Brandon R. Mcfadden, Sarah Meyer, John C. Bernard

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Cattle production is estimated to be the largest methane (CH₄) emitter associated with consumer demand in the United States of America (U.S.). With a national commitment to reducing methane emissions by 30% before 2030, methane-reducing additives (MRAs) in livestock feed are being explored as a viable solution. This study investigated consumer preferences for low-methane ground beef produced using one of three MRAs with varying levels of methane mitigation: Aspagopsis taxiformis (seaweed), the organic compound 3-nitroxypropanol (3NOP), or a blend of essential oils (e.g. garlic extract and citrus). In a nationally representative survey, 3,009 respondents completed a labeled discrete …

Parting The Corn Rows: Nikita Khrushchev’S Visit To Iowa, 1959, Jordan Stiles

Dissertations and Theses @ UNI

On September 23, 1959, Soviet leader Nikita Khrushchev visited Roswell Garst to inspect US hybrid corn and agricultural methods. Khrushchev’s initial reforms are discussed to show why Khrushchev sought agricultural knowledge abroad. The details of Khrushchev’s and Garst’s life regarding their work in agriculture are explored up to the visit. The visit would leave an indelible mark on the USSR and Iowa. Khrushchev and his successors would use Garst’s model for hybrid corn farming as the template for Soviet farming. Garst would use his limelight to catapult his corn diplomacy into action around the world. Lastly, the legacy of Khrushchev’s …

Nexus Between Rural Agricultural Land Ownership And Agricultural Credits Access: A Case Of Tanzania, Gelas Rubakula

Journal of Humanities and Social Sciences

Agricultural investment in low- and middle-income countries faces credit access challenges. Several financial institutions, particularly banks, normally impose some conditions where the possession of a land title deed is required to access agricultural credits. This paper examines whether, and to what extent, rural agricultural land ownership influences agricultural credit access for rural farmers in Tanzania. The study focuses only on rural farmers and tries to find out whether these smallholder farmers can use their land, which is largely unformalized, as a collateral for credit access. The study survey was cross-sectional, using quantitative data collected in December 2017 to March 2018 …

Leveraging Social Ties To Financial Gains: Exploring The Impact Of Social Capital In Rural Development, Mallory L. Rahe, Andrew J. Van Leuven, Trey Malone

Department of Agricultural Economics Faculty Publications

Social capital, defined as networks of individuals linked through bonding or bridging relationships, plays a crucial but poorly conceptualized role in place-based development. The word “capital” implies an underlying value of the social connections throughout a community, and this study explores how these social relationships are used to initiate, plan, access financial capital, and implement economic development projects in rural areas. We avoid county-level aggregation bias and use a divergent pathway case study of projects across eight communities to examine how social ties are used during rural development in places with both high and low financial capital. Both types of …

Place Branding: More Than Just A Logo, Marilyn R. Schlake

Cornhusker Economics

Place branding can distinguish one community from another. In a landscape of locations that provide the same amenities, environments, and opportunities, branding can help a community “stand out.” However, what is usually missing is a place brand developed in association with the community’s history, values, social connections, and organization associations that have evolved.
