The Role of Models in Farm Systems for GHG Mitigation 18Nov2021
From Jenifer Wightman
As part of the Working Lands & GHG webinar Series "Understanding and Reducing Greenhouse Gas (GHG) Emissions in Agriculture & Forestry", this talk features Kristan Foster Reed and her exploration of different models for managing Livestock GHG emissions and mitigation.
ABSTRACT: Dairy farms are complex systems with the main sources of GHG emissions coming from enteric methane, manure management, and feed production. However, opportunities exist to mitigate emissions from each of these sources and due to the nature of the dairy farm system, a single management decision can mitigate multiple emission sources. Models are tools that help us understand the downstream impacts of management practices and quantify emissions and other environmental impacts. I will review some existing dairy farm system models and introduce the Ruminant Farm Systems model currently under development.
Bio of Kristan Foster Reed
Kristan grew up on St. Croix in the US Virgin Islands before earning her B.S. in Animal Science from Cornell University. She spent three years as a Peace Corps Volunteer in the mountain nation of Lesotho before returning to school to complete a Ph.D. in Animal Biology at the University of California at Davis. She has a research and extension position in the Department of Animal Science at Cornell focused on using modeling tools to support dairy farm management. The Ruminant Farm System model is a major component of her research program, through which, she aims to improve dairy production efficiency and sustainability.
Some models she explores in this talk include;
