OverviewAI-generated summary
Greg Thoma's research focuses on the environmental and economic impacts of agricultural systems, with a particular emphasis on life cycle assessment (LCA). His work investigates the environmental footprints of various food production processes, including dairy, swine, and beef cattle operations, as well as fruit, vegetable, and rice cultivation. Thoma has examined greenhouse gas emissions associated with milk production and consumption, and explored strategies for managing manure in dairy and swine operations to promote sustainability.
His research also extends to understanding the environmental consequences of agricultural challenges, such as the impact of the rice blast pathogen. He has investigated the phytoremediation of contaminated soils and considered the broader implications of environmental sustainability within food supply chains, especially in the context of climate change. Thoma's scholarly contributions are reflected in his h-index of 38 and over 170 publications, with significant collaborations with researchers at the University of Arkansas at Fayetteville, including Marty D. Matlock, Lauren F. Greenlee, Zahra Anari, and Karla G. Morrissey.
