- 요약Iowa, a leading state in agricultural production, faces significant environmental challenges due to nitrogen pollution from nutrient runoff, primarily driven by its dominant corn, soybean, and livestock farming practices. This dissertation investigates sustainable management strategies for Iowa's Food-Energy-Water (IFEW) nexus, focusing on a county-level, framework-based, and data-driven approach to reducing nitrogen pollution. By examining the interdependencies between agricultural productivity, energy production, and water management, the research provides insights into mitigating nitrogen surplus and enhancing the sustainability of Iowa's agricultural systems.The first chapter introduces Iowa's agricultural landscape and the environmental issues related to nitrogen management. It emphasizes the critical need for integrated approaches to address the interactions between food production, energy use, and water quality in the state.Chapter two presents a comprehensive county-level analysis of Iowa's nitrogen fluxes, drawing on data from cropland, livestock, and ethanol production systems. This spatial-temporal analysis reveals the variability of nitrogen surplus across Iowa's counties and the key role of ethanol production in influencing nitrogen dynamics. The results highlight the need for region-specific management strategies to effectively address nitrogen pollution and promote environmental sustainability.In chapter three, the dissertation introduces the IFEWs Miles framework, which expands the traditional Food Miles concept to include energy systems and their environmental impacts. This framework examines the transportation logistics of corn for ethanol production and manure for nutrient recycling, assessing how these factors affect nitrogen management. While ethanol production shows potential for reducing nitrogen surplus, logistical challenges, particularly related to manure transportation, limit its broader application as a sustainable nitrogen source. The findings call for infrastructure improvements and policy support to enhance nutrient management and reduce nitrogen pollution from nutrient runoff.The fourth chapter focuses on the development of a Multi-Criteria Decision-Making (MCDM) framework that optimizes land use by balancing agricultural productivity, environmental sustainability, and economic viability. This decision-support tool evaluates trade-offs between economic and environmental outcomes at the county level, allowing stakeholders to assess the impact of different land-use strategies. The MCDM framework offers a practical approach to sustainable resource management, providing insights for land-use planners and policymakers.In combining these diverse but interconnected studies, this dissertation offers insights into the challenges and opportunities associated with managing IFEWs. By addressing nitrogen management through both spatially detailed data and decision-support frameworks, this research provides practical pathways for improving nutrient management and reducing pollution in Iowa's agricultural systems. The findings contribute to a more comprehensive understanding of the Food-Energy-Water (FEW) nexus and offer valuable guidance for policymakers, land-use planners, and stakeholders aiming to promote sustainable practices in regions with similar agricultural and environmental challenges.
