The Role Of Farmer Heterogeneity In Nutrient Management: A Farm-Level Analysis, Hua Wang, Naveen Adusumilli, Daniel Fromme, Keith Shannon

Journal of Applied Farm Economics

Understanding farmer heterogeneity regarding nutrient management decisions is crucial for the success of any nonpoint source pollution prevention programs. Data from a farm- level experiment of cover crops in corn production were used in the Stochastic Efficiency with Respect to a Function framework to examine preference for nitrogen strategies over a range of risk aversion levels. We show the highest net return and certainty equivalent to the consideration of N supplied by cover crops. The results provide insights into policy discussions about the level of conservation incentives and plans that offer solutions to mitigate nonpoint source pollution.

The Custom Service Industry's Role In Precision Agriculture Adoption: A Literature Review, Scott W. Fausti, Bruce Erickson, David Clay, Sharon Clay

Agronomy, Horticulture and Plant Science Faculty Publications

This literature review focuses on the role of the precision agriculture (PA) custom services industry in facilitating farmer adoption of PA technology. Based on the review, a series of stylized facts are developed that characterize the custom services industry's role in the PA adoption process in the United States. The literature suggests that increasing the availability of custom services in local agricultural production markets will positively influence the rate of PA adoption. Recent PA custom services industry field surveys, however, indicate that skilled labor, proficient in PA technology, is critical to develop and provide custom services needed to increase the …

Is The Custom Service Industry's Role In Precision Agriculture Linked To Workforce Development?, Scott W. Fausti, Bruce Erickson, David Clay, Sharon Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Retail dealership survey data suggests that the lack of a qualified precision agriculture (PA) workforce limits the ability of the PA service industry to provide technological knowledge and services to producers who have adopted PA technology. The key empirical findings suggest that retail dealerships have the greatest difficulty finding workers who have, a) the capability to operate and collect data using specialized PA technology, b) the capability to interpret and develop management strategies using PA generated data, and c) a basic generalized competency in PA technology and its applications. The perceived shortage of skilled workers suggests that there is a …

Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

Farmers’ Adoption And Perceived Benefits Of Diversified Crop Rotations In The Margins Of U.S. Corn Belt, Tong Wang, Jin Hailong, Yubing Fan, Oladipo Obembe, Dapeng Li

Economics Faculty Publications

Monoculture and simplified two-crop rotation systems compromise the ecosystem services essential to crop production, diminish agricultural productivity, and cause detrimental effects on the environment. In contrast to the simplified two-crop rotation, diversified crop rotation (DCR) refers to rotation systems that contain three or more crops. Despite multiple benefits generated by DCR, its usage has dwindled over the past several decades. This paper examined determinants of farmers' adoption decisions and perceived benefits of DCR in the west margins of the U.S. Corn Belt where crop diversity has declined. We analyzed 708 farmer responses from a farmer survey conducted in the eastern …

Non-Tax Incentives And Agricultural Output In Nigeria, Elias A. Udeaja, Elijah O. Akanni, Emomotimi M. Question, Peter F. Offum, Titoluwa P. Eyinla

Economic and Financial Review

This study investigates the impact of non-tax incentives on agricultural sector output in Nigeria from 1981 to 2019, using Autoregressive Distributed Lag (ARDL) Model/Bounds test technique. The findings of this study show that non-tax incentives have a significant positive impact on agricultural sector output growth in the long-run; however, the effect was negative and statistically insignificant in the short run. On the other hand, government expenditure on agriculture was negative and significant on agricultural sector output growth in the short-run, while its long-run impact was also negative but not significant. Therefore, the study recommends targeted expansion of non-tax incentives to …

The key areas of advice that were progressed during the year were:

• mechanisms for funding biosecurity in WA
• the effectiveness of WA’s border biosecurity system
• how Western Australians perceive ‘biosecurity’ and their role in pest, weed and disease prevention, surveillance and response; and
• the quadruple bottom line of biosecurity.

An Examination Of Retail-Level Purchasing Behavior For Healthful Food In Louisiana, Marcus Coleman

LSU Doctoral Dissertations

Consumer access and choice for quality and affordable healthful foods at the retail-level is at the forefront of discussions related to the nutritional status of consumers in many communities across the United States. In Louisiana, many consumers live in food environments where retail options for quality and affordable healthful foods are limited, not affordable, or not available. Addressing these issues is complicated by the fact that literature focused on consumer access and choice for healthful foods at the retail-level in Louisiana is inadequate to play a significant role in addressing issues related to purchasing behavior for healthful foods faced by …

Apiculture Adaptations In A Shifting World: The Beekeeper’S Experience Across The Globe, Katherine Lloyd

Capstone Collection

Existing research suggests that changes in climate, such as rainfall and temperature shifts, will threaten bees’ main food sources and cause detrimental impacts on apiculture globally. Despite this, to the best of the author’s knowledge, there is little available by way of research relating to how beekeepers themselves experience these increased pressures to their practices. This research project investigated the experiences of beekeepers in the United States, Malawi, and Cameroon. Surveys of US beekeepers, and interviews with Malawian and Cameroonian beekeepers were coded for emergent themes and surveys were analyzed via descriptive statistics. Major differences in challenges reported by beekeepers …

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young

Faculty & Staff Research and Creative Activity

It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …

Comparing Heavy Metal Content Found In Spinach (Spinacia Oleracea) Grown On The Roof And Ground Sites At Portland State University, Tyler Robin, Gwynn R. Johnson, Olyssa Starry

McNair Symposium

As a result of urbanization, fresh, healthy food can be expensive and easily contaminated but space for local farming is limited. Roofs can be underutilized in densely populated cities and can offer a space for local fresh farming. The purpose of this study is to find if growing leafy vegetables on the roof can limit heavy metal exposure from air pollutants. By growing Spinach on five roofs and five ground locations around the Portland State University campus, at varying heights, we can extract the heavy metals found in these greens and compare them to each other. The expected results show …

Embodied Engineering : Gendered Labor, Food Security, And Taste In Twentieth-Century Mali, Laura Ann Twagira

Ohio University Press Open Access Books

Foregrounding African women’s ingenuity and labor, this pioneering case study shows how women in rural Mali have used technology to ensure food security through the colonial period, environmental crises, and postcolonial rule.

By advocating for an understanding of rural Malian women as engineers, Laura Ann Twagira rejects the persistent image of African women as subjects without technological knowledge or access and instead reveals a hidden history about gender, development, and improvisation. In so doing, she also significantly expands the scope of African science and technology studies.

Using the Office du Niger agricultural project as a case study, Twagira argues that …

Yield And Economic Performance Of Crop Rotation Systems In South Dakota, Hanxiao Feng, Tong Wang, Shannon L. Osborne, Sandeep Kumar

Economics Faculty Publications

Crop yield and economic profitability, both highly dependent on local crop management, soil characteristics, and weather conditions, are among the most influential factors to consider when considering a cropping system. The objective of this study was to compare the economic returns of three different 4-yr diverse crop rotations with that of a 2-yr traditional crop rotation in eastern South Dakota. The rotations included were (a) corn (Zea mays L.)–soybean [Glycine max (L.) Merr.]–spring wheat (Triticum aestivum L.)–pea (Pisum sativum L.) (CSSwP), (b) corn–pea–winter wheat–soybean (CPWwS), (c) corn–oat (Avena sativa L.)–winter wheat–soybean (COWwS), and (d) corn–soybean …

Cash Transfers And Temptation Goods: An Analysis On The Impact Of Cash Transfers On Poor Households’ Consumption Of Sugar-Sweetened Beverages In The Philippines, Janelle S. Tiu, Vince Eisen C. Yao

Angelo King Institute for Economic and Business Studies (AKI)

Sugar intake has been increasing globally and locally for individuals. Meanwhile, Philippine institutions continue to provide cash transfers (CTs) to poor households. Past literature found varying results of the impact of transfers on expenditure, consumption, and temptation goods. Most studies focused on alcohol and tobacco consumption and neglected the impact of cash transfers on the consumption of sugar-sweetened beverages (SSBs). Thus, this paper used propensity score matching and average treatment effects on the treated (ATET) evaluation method to compare the consumption of poor households with transfers to their consumption if they had not received cash transfers and determine the characteristics …

Climate Adaptation And Water Conservation Decision-Making In Paso Robles, California Vineyards, Christopher R. Klier

Master's Theses

A survey was distributed to all 220 vineyards and vineyard management companies that operate in the AVA, with a 53.64% response rate. The objective of the survey was to determine vineyard manager and owner attitudes towards climate change and adaptation, as well as their perceptions of how these threats would impact their operation. A second objective was to document the current level of water conservation and climate adaptation while identifying the barriers and opportunities for further adoption …

Perceptions Of Future Community And Individual Well-Being In Rural Nebraska, Amanda L. Kowalewski

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Populations of rural areas continue to decline, yet some communities are more vibrant than ever. While past research has studied current satisfaction or well-being, few have examined future well-being. Using an ordinal logistic regression and combining primary and secondary data sources, this study investigates the predictors of rural Nebraskan’s sense of future well-being, both at the community and individual levels. The model indicates that resilience may be more important in well-being than social capital. Additionally, certain satisfaction indicators are more important than others. Factor analysis was employed to re-index variables, and findings were similar. Social capital, resilience, and quality of …
