Why Agtech Startups Fail? Evidence From Global Shutdown Patterns In 2025 And The Cost-Adoption Mismatch Effect, Ankit Chandra, Ishani Lal

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural technologies are widely seen as a driver for sustainability, resilience, and food-system transformation. Yet in 2025, agtech startup across North America, Europe, Asia, and Africa experienced multiple shutdowns. Although each company closed for its own reasons, the failures highlight consistent underlying patterns. We analyze 18 publicly reported shutdowns across controlled-environment agriculture (CEA), robotics, insect protein, digital platforms, sensors, and ag-biotechnology. We find that most ventures struggled not with scientific feasibility but with economic and adoption dynamics at the farm level. We identify a Cost-Adoption Mismatch Effect, in which the capital and operational burden of a technology exceeds farmers’ capacity …

Digital models aim to reduce natural environments into controllable game-like situations and undermine …

Brewing Resilience: Cooperatives, Micro-Mills, And The Quest For Survival In Costa Rica's Changing Coffee Landscape, Leila N. Iredell

Honors Theses

This thesis examines how different organizational models in Costa Rica's coffee sector shape producers’ ability to capture value, build resilience, and sustain rural livelihoods in a rapidly changing global market. In comparing traditional cooperatives and new micro-mills, I examine specifically how control over the value chain, access to markets, and social infrastructure differ across models and what these differences mean for the farmers who depend on them. This project analyzes how the collapse of international price agreements and decades of market volatility drove producers toward new strategies, from independent processing and direct trade to coffee tourism. Costa Rica stands as …

Between The Rails: Experiential Education And Its Impact On Compliance And Consistency In Racetrack Surface Management, Heather Mackenzie

Theses and Dissertations--Community & Leadership Development

Recent regulatory requirements within the Thoroughbred racing industry have increased expectations for consistent collection and reporting of racetrack surface data. Despite clear standards, implementation in daily operations remains inconsistent, highlighting a gap between regulation, knowledge, and practice. This study examined the impact of an experiential education curriculum on racetrack personnel’s self-efficacy and reporting consistency.

Using a quantitative design, data were collected through pre- and post-surveys measuring self-efficacy and records of the number of days surface data were entered.

To explore the potential of GM crops, this paper examines their production, adoption, economic and environmental impacts, adoption barriers, and policy implications in Africa and globally. This is done using a structured narrative review of peer-reviewed literature, reports, and policy documents (2014–2024) sourced from different databases complemented by stakeholder consultations. The findings show that GM has expanded considerably worldwide driven by high productivity, reduced pesticide …

From Fruit To Nut: Revisiting Pili Nut (Canarium Ovatum Engl.) Production Capacities And Value-Adding Activities In Sorsogon, Philippines, Joey Richard V. Dio, Ryan V. Dio, Dulce Corazon F. Lacson

The Philippine Agricultural Scientist

The value chain of agricultural products significantly influences their profitability and socio-economic contribution. This study developed a descriptive model of the pili (Canarium ovatum Engl.) nut value chain in Sorsogon, the primary producer in the Philippines, and the only province with large-scale commercial operations. Using a descriptive research approach, data were collected through purposive interviews with 15 key informants—farmers, processors, and traders—guided by Porter’s value-chain framework. Results indicate that Sorsogon produces about 3 times the quantity required daily (< 2,233 kg) by Bicol-based processors, leading to underutilization and post-harvest losses attributed to limited storage facilities and market linkages. The processing stage, which converts pili fruits into nuts and kernels, demonstrates the highest operational efficiency, while the trading stage remains constrained by limited market access. Stakeholders often perform overlapping functions, and traditional sun-drying methods remain common. Furthermore, an aging farming population, limited succession planning, and inconsistent implementation of food safety standards continue to pose challenges to industry growth. These inefficiencies result in reduced profitability and restrict expansion. Strengthening the value chain through improved processing systems, broader market integration, and streamlined production activities is necessary to enhance economic returns and support the sustainable growth of Sorsogon’s pili nut industry.

Characterizing The Relationship Between Parturition In Beef Cattle And The Lunar Phase And Meteorological Factors., Caroline E. Chambers

Honors College Theses

For beef cattle, parturition is one of the most critical stages in the reproductive process. It is crucial that farmers understand the factors that may influence the timing of parturition. There is a persistent preconception that the onset of parturition is influenced by the lunar phase and weather factors. The objective of this study is to characterize the association between parturition in beef cattle, the lunar phase, and/or different weather factors such as barometric pressure and temperature. Cattle records were obtained from Chambers Family Farm in Cumberland Furnace, TN. Data was collected from 142 calvings from January 2017 to October …

National Halo And Culture Mixing: U.S. Consumer Acceptance Of Korean Cultivated Meat Made With Seaweed Components, Mark Chong, Angela K. Y. Leung, Tricia Marjorie Fernandez

Research Collection Lee Kong Chian School Of Business

The purpose of this qualitative study was to investigate U.S. consumers’ perception and acceptance of a “culturally mixed” product – i.e., cultivated meat (beef) made with Korean seaweed components – a product that involves the blending of a foreign cultural element (Korean seaweed) with a local cultural element (cultivated beef) to create a mixed cultural representation. Subsequently, it aimed to assess if the product’s country of origin (i.e., South Korea) would influence consumer perception and acceptance. Online in-depth interviews were conducted with 20 U.S. consumers recruited through two market research companies. The interview transcripts were analyzed by two trained coders …

Human Capital, Immigration, And Growth: A State-Level Dynamic Panel Study, William R. Cooper

Graduate Theses and Dissertations (2019 - present)

This study examines whether who immigrates, rather than how many, matters for state economic growth in the United States. It integrates a policy-relevant proxy for skill (H-1B approvals) into an augmented Solow framework that separates immigration's quantity channel from its human capital channel and estimates dynamic effects in a balanced quarterly panel of 50 states (2010 to 2023 ). The empirical strategy estimates a two-step difference GMM Arellano-Bond model that reinforces identification using a double/debiased machine learning (DML) variant that orthogonalizes high-dimensional nuisance components via cross-fitting. This design targets the distinct roles of immigrant headcount versus skill in per capita …

Economically Optimal Soil Sampling Density And Application Technology For Potassium Fertilizer For Soybean In The Mid-Southern Us, Bayarbat Badarch, Aurelie Poncet, Shelby Ridar, Nathan Slaton, Michael Popp

Agricultural Economics and Agribusiness Faculty Publications and Presentations

To maximize beneficial potassium (K) fertilizer use in irrigated soybean (Glycine max. (L.) Merr.) fields with spatially varying soil-test K (STK), the value of added information from more precise STK maps must be greater than the associated information collection costs. In eleven fields, we modeled the impact of soil sampling densities (SD) ranging from 2.2 samples ha-1 in the largest field (41.2 ha) to 13.59 samples ha-1 in the smallest field (7.4 ha) on STK maps with 0.4 ha grid size. The accuracy of profit-maximizing fertilizer rate prescription maps varied by SD and subsequent yield estimates using either uniform …

Sentiment Analysis Of Public Commentary On U.S. Farm Bills, Frank Tenkorang, Fletcher Ziwoya

Mountain Plains Business Conference

This study applies sentiment analysis to public commentary on U.S. farm bills to assess patterns of support and opposition. Using Reddit posts from relevant subreddits, we employed two natural language processing models, VADER and RoBERTa, to evaluate sentiment over time. While both models yielded differing sentiment distributions, they revealed increased public engagement during farm bill years, particularly in 2018. Most sentiments were neutral, but negative opinions outweighed positive ones. Posts with stronger sentiments tended to attract more user interaction, especially controversial ones. These findings highlight the polarized yet active public discourse surrounding agricultural policy and the potential for data-driven policy …

Will Labor-Saving Automation Save Western Agriculture?, Lynn Hamilton, Bryan Lohmar, Michael Mccullough

Agribusiness

Among the most salient and intractable challenges facing labor-intensive western agriculture is the rapidly rising cost of labor, driven primarily by reduced availability of workers. Unlike field grains, oilseeds, and cotton, producers of fresh fruit and vegetables still rely extensively on hired manual labor to carry out multiple tasks, particularly harvesting. Nearly one third of total U.S. agricultural labor expenses occur in California alone, a state dominated by fruit, vegetable and horticultural (FVH) crops (Win, Rutledge, and Maredia, 2024). To address the rising cost of labor, producers have been adopting several innovations leading to automated irrigating, weeding, and crop protection …
