Chad Hellwinckel

Chad’s work with the BEAG focuses on agricultural land use policies, climate change mitigation, biofuels analysis and defining appropriate long-term agricultural policy in a post peak-oil world. He maintains and uses computer models designed to estimate the local and national effects of implementing agricultural policies upon land-use, farm incomes and the environment. Recent projects include building a geographically precise terrestrial carbon sequestration model which can also estimate potential quantities of biomass available from agricultural lands for energy uses. This model has been used to analyze the interactions between simultaneous climate change and biomass policies.

Chad received a doctorate in geography at the University of Tennessee in 2008. He received his MS in Agricultural Economics from the University of Tennessee in 1996, and a BS in Economics and Urban Studies from St. Olaf College in 1991. Chad has worked at The Land Institute, in Salina Kansas, and served as a Peace Corps volunteer in Panama and with the US Forest Service in Arizona, New Mexico and Utah. He is also the founder of the Knoxville Permaculture Guild.
