GIS Seminar: Understanding IFEWs Miles: Navigating the Nexus of Manure and Energy in Iowa

April 22 @ 12:00 pm - 12:50 pm

Presenter: JĂșlia Brittes Tuthill, Agricultural and Biosystems Engineering, GIS Certificate Candidate
Advisor: Dr. Amy Kaleita


Excess nitrogen from agriculture, particularly in Iowa, poses environmental risks like eutrophication, affecting ecosystems and water safety. Understanding the water-related impacts of agricultural nitrogen is vital for environmental improvements. The Iowa Food-Energy-Water (IFEW) nexus links food, energy, and water production and distribution, which is crucial in Iowa due to its substantial agricultural output and ethanol production. The IFEWs Miles initiative concentrates on tracing the routes and water quality implications of transporting corn and soybeans to ethanol and biodiesel plants, as well as the feasibility of using manure as organic fertilizer for corn crops within a specific radius, typically limited to 20 miles. This approach aims to deepen the understanding of the logistical and ecological aspects of biofuel production and organic fertilization in Iowa’s agricultural system. However, this agricultural intensity creates a nitrogen surplus, harming water quality. Challenges in transporting by-products like manure exacerbate environmental issues. The IFEWs Miles framework aims to detail the environmental impact of Iowa’s agricultural practices, guiding sustainable farming policies to enhance water quality and ecosystem health.

The GIS Seminar Series is hosted by the Department of Community and Regional Planning.
