  • Lamb Growth and Seasonal Herbage Production from Simple, Diverse, and Legume Pastures Established in an Agrivoltaic System

    Creator:
    Andrew, Alyssa C.
    Abstract:
    Agrivoltaic systems promote dual use of land by combining solar energy and agricultural production. Grazing sheep in these systems is popular but research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pasture mixes...

  • Leveraging the Food-Energy-Water Nexus for Planet Resilience

    Creator:
    Steadman, Casey L.
    Abstract:
    We have sufficient evidence that our historical management of natural resources is not sustainable. Food production is stagnating or declining. Nonrenewable energy sources on which the energy sector has historically depended are being rapidly depleted. Water resources, for which the energy and food sectors compete, are being depleted and impaired....

  • Modeling the effect of longwave radiation from solar panels on soil moisture

    Creator:
    Shepard, Laurel A.
    Abstract:
    Agrivoltaics, which integrates photovoltaic power production with agriculture in the same plot of land, has the potential to reduce land competition and crop irrigation. To optimize agrivoltaic systems for crop growth, energy pathways must be characterized. While solar panels shade the crops, they also emit longwave radiation. At the end...

  • Environmental Impacts of Renewable Energy (solar and wind) on Water, Food and Energy Nexus

    Creator:
    Hassanpour Adeh, Elnaz
    Abstract:
    Rapid increasing of renewable energies and the knowledge about their environmental effects are very limited. As a result, the renewable energies (e.g. solar or wind energies) will play a vital role in the future because it is well accepted by environmental friendly industries. This dissertation presents the modeling, data analysis...

  • Irrigation Innovations to Increase Efficiency and Sustainability

    Creator:
    Al-agele, Hadi A.
    Abstract:
    The first part of the dissertation chronicles irrigation technology changes to progressively improve water application efficiency, water use efficiency, irrigation water productivity and crop production. Technological innovation in irrigation, from 6000 BC to present, has been driven by an unchanging need to provide support for growing populations. The first irrigation...

  • The field edge flux paradox

    Creator:
    Barr, Colleen M.
    Abstract:
    Precision irrigation has made spatially explicit water management a reality. However, detailed knowledge about the spatially variable evapotranspiration is often unavailable. One example location where we can begin to understand the impact of spatial variability on evapotranspiration is at the field edge, which contains a sharp discontinuity in surface conditions....

  • An Experimental Investigation of Interstitial Air Movement in Seasonal Snow

    Creator:
    Drake, Stephen A.
    Abstract:
    Atmospheric pressure changes do not stop at the permeable snow surface but rather propagate into it. These pressure changes range from high-amplitude, low-frequency events caused by seasonal cycles and synoptic weather systems to small-amplitude, high-frequency events caused by topographic features and turbulence. The effect of pressure changes on interstitial air...

  • Hydraulic Conductivity of The Hemp Stems Under Water Stress

    Creator:
    Yuksel, Mehmet
    Abstract:
    Hydraulic conductivity of hemp stems under water-stress conditions was investigated. When plants face with water-stress conditions, embolies (cavitation) are triggered in xylem channels and water transport from the root to the leaves is affected. The relation between percentage loss of water transfer ability within the xylem channels can be described...

  • Measuring Tomato Production and Water Productivity in Agrivoltaic Systems

    Creator:
    Al-agele, Hadi A.
    Abstract:
    Growing populations and industrialization rates across the world are leading to increased food and energy demand. The challenge of meeting this demand while also mitigating climate change impacts serves as a driving force for the development of renewable energies technologies. This study focuses on the role of Agrivoltaic systems in...

  • Harvesting Sunshine: A Modular Integrated Framework for Modeling the Agrivoltaic System

    Creator:
    Proctor, Kyle W.
    Abstract:
    Understanding the interplay between energy and water is central to effective natural resource management. With enough energy it is possible to secure sufficient water, with enough water it is possible to produce nearly boundless energy. The sun is the engine which drives the availability of both these resources; nearly every...
