Harmful Algal Blooms: Risks For Food In Utah, Jose Brandao, Sarah Erwin, Stephanie Vaughn, Clare Entwistle

All Current Publications

Harmful algal blooms (HABs) are a problem because they can produce toxins that make water unsafe for people, animals, and the environment. In recent years, HABs have emerged as a growing concern in freshwater systems throughout Utah, including irrigation canals, reservoirs, and livestock ponds. HABs in freshwater are caused by cyanobacteria, also called blue-green algae. These microorganisms can release dangerous toxins that can harm swimmers, pets, and the food supply. Unlike foodborne pathogens, these toxins cannot be removed by boiling, cooking, or washing the food. Therefore, regular monitoring is essential to detect HABs early and reduce exposure risks. This fact …

From Insight To Impact: Segmenting Consumers By Their Regenerative Agriculture Priorities, Lourival Carmo Monaco Neto, Gustavo Stevanin De Souza, Owen Jerome Zakrzewski, Allan Wayne Gray

Department of Agricultural Economics Faculty Publications

Regenerative agriculture is gaining traction in agrifood value chains, yet its definitional ambiguity and the heterogeneity of consumer priorities create strategic challenges for commercialization. Firms commonly assume a homogeneous ‘sustainable consumer’ motivated by environmental outcomes, but research on consumer food values suggests that economic attributes often outweigh environmental concerns when trade-offs are required. This study segments U.S. consumers based on how they prioritize seven core attributes of regenerative agriculture: soil health, biodiversity, greenhouse gas emissions, water use, food prices, crop yield, and farmer profitability. Using forced-ranking data from 1231 nationally representative U.S. consumers surveyed in August 2024, we apply a …

Cultivating Narratives: A Critical Discourse Analysis Of Higher Education Student-Led Farms And Gardens, Maximilan Sherard, Marc T. Sager

Publications

Despite extensive research on community agriculture, little attention has been paid to student-led farms or gardens (SFGs) in higher education contexts. SFGs represent a unique site for community agriculture due to their diverse stakeholders, academic affiliations, and the institutional policies they navigate. This study examines online promotional materials from 42 SFGs located on land-grant higher education campuses across the United States. Using critical discourse analysis, we (1) map these organizations’ practices and (2) identify competing discourses about community and agriculture within their promotional narratives. We identify and explain four core practices (membership, growing, distribution, and purpose) and connect these practices …

Nebraska And The Midwest Agtech Ecosystem: Benchmarking Innovation Investment And Translation Gaps, Ankit Chandra, Ishani Lal, Brennan Costello

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

Agricultural innovation is central to the sustainable transformation of food systems, yet the capital that finances it is unevenly distributed relative to where food is produced. This paper develops a diagnostic framework for measuring this mismatch and applies it across the U.S. Midwest from 2021 to 2025, with particular emphasis on Nebraska's structural position within this landscape. Drawing on venture capital deal-flow data, 17 stakeholder interviews, and a novel strength-weakness-opportunity-gap (SWOG) ecosystem mapping methodology, we document $736 million in tracked Midwest AgTech funding across eight states (Nebraska, Iowa, Missouri, Illinois, Indiana, Kansas, North Dakota, and South Dakota).
