Episode 24: Why anaerobic digestion?
Anaerobic digestion is a biological process in which microbes break down organic matter to produce biogas. This process captures the biogas, which can be harmful to the atmosphere and uses it for energy. Dr. Brandon Gilroyed, a professor in the School of Environmental Science at the Ridgetown Campus, chats with Graeme about his research in this area, highlighting how it works and the environmental benefits. This is our last podcast episode for a little while, but we will be back soon! A transcript for episode 24 can be found here. [9]
Episode 23: How does cannabis legalization affect rural B.C. communities?
Before recreational cannabis became legal in Canada in 2018, some rural communities in British Columbia relied on the illicit market for economic well-being. Legalization disrupted these communities’ way of life. Tracey Harvey, a PhD candidate in the School of Environmental Design and Rural Development, is researching the implications of cannabis legalization on these communities. She talks to Graeme and Jordan about the history of the illicit market, her methods for conducting research, and how her research will help support these rural economies. A transcript for episode 23 can be found here. [10]
Episode 22: How do we get research in the right hands?
Producing informative research is the goal of all our guests, but ensuring that groundbreaking research is actually used is the focus of Dr. Amy Lemay. Amy, who is a post-doc researcher in the Department of Plant Agriculture, is working to determine why Integrated Pest Management practices (based on research findings) have been so widely adopted by farmers. She explains the “sociology of science”, why knowledge translation and transfer is critical to research adoption and how she’s hoping her own research will help others translate theirs into common practice. A transcript for episode 22 can be found here. [11]
Episode 21: How do the processed foods (we love) affect our health?
Ultra-processed foods are dominant in our Western diet, and this doesn't just include pop and chips. Many processed foods that consumers consider to be healthy (based on their ingredients) are negatively affecting our health. Dr. Mike Rogers, a professor in the Department of Food Science, explains the evolution of our diet and the impacts of processed food on our bodies. He also unpacks the complications of our current food system, which prioritizes technological innovation over understanding the impacts on our health. A transcript for episode 21 can be found here. [12]
Episode 20: How is cow health connected to farmer mental health?
Using robots to care for dairy cows might sound a bit cold or even dystopian to some, but researcher Dr. Meagan King found a connection between automation and positive health benefits for both dairy cows and the farmers who care for them. In this episode, Meagan talks to Graeme and Jordan all about dairy cows and explains how her research in the Department of Animal Biosciences showcases the linkage between automation, strong herd health and benefits for farmer mental health. Note: Meagan received permission to visit and work with farms/farmers and followed policy set by the University of Guelph Research Ethics Board. The research discussed in this episode, and all animal research at the University of Guelph, is done in adherence to the University of Guelph Animal Care Policy and Procedures.
