Abstract:
Transforming today’s economic system from a linear “take-make-waste” model to a circular bioeconomy—focused on reducing, recycling, recovering, reusing, and regenerating resources—has emerged as a critical strategy for meeting global food and fuel demands sustainably. While this transition is widely viewed as essential, Dr. Khanna emphasizes the need to move beyond purely technological solutions. Her lecture will explore how economic frameworks can help balance the costs, benefits, and broader environmental and societal impacts of circular systems. She will also discuss the mechanisms sustaining the current linear economy, potential pathways toward a circular bioeconomy, and the policy decisions required in a decentralized market system.
The Filley-Garey Lecture is a longstanding tradition that brings leading scholars to campus to engage with students, faculty, and the public on pressing issues in agricultural and environmental economics.
