Sam Bliss is a postdoctoral fellow in two departments at the University of Vermont: he does research in the Department of Nutrition and Food Sciences and teaches ecological economics in Community Development and Applied Economics. In 2023, he completed a PhD in Natural Resources on how and why Vermonters produce and distribute food that's not for sale. Sam is continuing this line of research as a postdoc, studying how home and wild food production influence food security, health, and environmental outcomes in high-income societies. During his seven years of fieldwork on non-market food practices in northern New England, he has not only interviewed more than one hundred practitioners but also gardened, foraged, spearfished, dumpster-dived, raised chickens, slaughtered livestock, and coordinated Food Not Bombs Burlington, a mutual aid project that has shared lunch with all comers behind a downtown parking garage every day since March 2020. Sam is also a frequent public speaker on non-market economies and degrowth. Before coming to Vermont, he was a Fulbright Fellow at the Autonomous University of Barcelona.
