The Influence Of Local Embeddedness On The Economic, Social, And Environmental Sustainability Practices Of Regional Small Firms, Jalleh Sharafizad, Janice Redmond, Craig Parker

Research outputs 2022 to 2026

Despite growing research on economic, social, and environmental sustainability, few studies explore all three sustainability pillars and implemented practices, in the context of regional small firms. This study uses a novel integration of two theoretical concepts, local embeddedness, and sustainability embeddedness orientation, to fill this knowledge gap. Using 26 interviews, the study highlights the nuanced interconnectedness of three new theoretical concepts that link local embeddedness and sustainability embeddedness–locally embedded sustainability values, spatially-driven sustainability and locally adapted sustainability. An integrated theoretical framework is provided that uses the three new concepts to explain how and why small firm local embeddedness in regional …

Saving The Campus Farm: One Approach To Leveraging Institutional Support For A Campus Farm Space, Julia L. Angstmann

Scholarship and Professional Work - LAS

The number of university and college campus farms have increased 13-fold since 1992 to over 300 campuses (LaCharite, 2016). According to reporting by the Association for the Advancement of Sustainability in Higher Education (AASHE) (2018), 80% of campus farm spaces are less than 5 acres in size and 86% are located on campuses with no agriculture school (AASHE, 2018). Campus farms provide a rich interdisciplinary social context of community based, sustainable agriculture that spans the entire suite of social and physical sciences as well as non-STEM fields such as business, religious studies, and communication. Yet, the majority of these farm …

The Use Of Microalgal Sourced Biodiesel To Help Underground Mines Transition To Battery Electric Vehicles, Corey A. Laamanen, Kyle Moreau, Sabrina M. Desjardins, Shannon H. Mclean, John A. Scott

Journal of Sustainable Mining

The use of fossil fuel sourced diesel underground has various associated health and environmental hazards, and additional energy demand and costs associated with necessary ventilation. One way to reduce these impacts is by utilizing a biodieselblend, which generates lower levels of harmful emissions from underground equipment and can be produced regionally, reducing the impact of transportation. Furthermore, this would help allow use of existing machinery during transition towards more widespread electrification underground. Therefore, the concept of an integrated supply and use chain within the mining industry is examined based on biodiesel from acidophilic photosynthetic microalgae cultivated using CO 2 in …

Ferrihydrite Enrichment In The Rhizosphere Of Unsaturated Soil Improves Nutrient Retention While Limiting Arsenic And Uranium Plant Uptake, Arindam Malakar, Daniel D. Snow, Michael Kaiser, Jordan Shields, Bijesh Maharjan, Harkamal Walia, Daran Rudnick, Chittaranjan Ray

Nebraska Water Center: Faculty Publications

Improvement of nutrient use efficiency and limiting trace elements such as arsenic and uranium bioavailability is critical for sustainable agriculture and food safety. Arsenic and uranium possess different properties and mobility in soils, which complicates the effort to reduce their uptake by plants. Here, we postulate that unsaturated soil amended with ferrihydrite nanominerals leads to improved nutrient retention and helps reduce uptake of these geogenic contaminants. Unsaturated soil is primarily oxic and can provide a stable environment for ferrihydrite nanominerals. To demonstrate the utility of ferrihydrite soil amendment, maize was grown in an unsaturated agricultural soil that is known to …

Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson, Fiona Goggin

Inquiry: The University of Arkansas Undergraduate Research Journal

Plant elicitor peptides (Peps) – endogenous chains of amino acids involved in natural plant defense – have been shown to decrease damage from herbivores and pathogens by inducing an immune response, increasing the emission of volatile organic compounds (VOCS), transcripts, and metabolites. Exogenous treatment of soybean seeds with plant elicitor peptide GmPep3 has been shown to induce these broad-spectrum defenses and offers a new method for increasing crop yield. However, the effects of GmPep3 on indicators of soybean health – root characteristics, growth stages, etc. – have not been fully realized. Using the root-phenotyping platform RhizoVision Explorer, several root traits …

Future Climate Streamflow Estimation In The Donnelly River Catchment, Justin Hughes, Bill Wang

Natural resources commissioned reports

The Donnelly River is located in the south-west of Western Australia. An irrigation development has been proposed in the catchment that would extract water from the Donnelly River and store this in an off stream reservoir for irrigation use. Given the known issues related to non-stationarity and hydrological prediction, the Department of Primary Industries and Regional Development (DPIRD) contracted CSIRO to review the hydrological model that was used to estimate future climate streamflow in the Donnelly River. This model was owned and operated by the Department of Water and Environmental Regulation (DWER). The CSIRO review of the model, which also …

An abundance of waste methane gas is produced on the International Space Station (ISS) as a result of the Sabatier Reaction, a part of the Environmental Control and Life Support System (ECLSS). In order to manage this organic waste, this experiment seeks to understand how microgravity impacts the methane-oxidizing metabolism of methanotrophic bacteria, namely Methylorubrum podarium. As methanotrophs have never been studied in space, this investigation may unlock a novel understanding of their behavior in microgravity, leading to promising future applications such as improved life support systems in deep space. In this experiment, cameras will capture snapshots of the bacterial …

Disability And Climate Change: A Critical Realist Model Of Climate Justice, Molly M. King, Maria A. Gregg

Sociology

Existing literature on climate change as an issue of environmental justice documents the heightened vulnerability of people with disabilities to the effects of climate change. Additionally, there are numerous studies showing that access to information is a prerequisite for perceiving risk and taking action. Building on this work, our review seeks to understand how physical disability relates to perceptions of climate-related risk and adaptations to climate-related events. We introduce a critical realist model of climate justice to understand the relationships between the environmental features that disable, risk perception and information seeking, and adaptive capacity and resilience to climate change. In …

Regenerating Agroecosystems By Overcoming Human Exceptionalism In Designing For Increased Equity Of Benefits From Ecoservices, Ali Loker, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Our commentary explores three critical issues related to ecosystem services. First is how ecoservices are currently designed and implemented primarily for human benefit without concern for how these impact other species. We conclude that awareness of this imbalance is the first step toward meaningful change. Second we observe that human exceptionalism guides most decisions, and ask whether we can overcome this mind-set to embrace ecoregeneration and design of resilient and mutually beneficial agroecosystems. Our attitude toward the challenge and moving toward greater humility about human roles that guide management decisions in the ecosystem is a requisite for change. Third we …
