V. Ernesto Méndez, PhD, is an associate professor of agroecology and environmental studies at the University of Vermont, where he leads the Agroecology and Rural Livelihoods Group, a community of practice that studies and contributes to developing practical solutions to key issues in our current agrifood system. He earned his PhD in agroecology and environmental studies from the University of California at Santa Cruz. His empirical work is mostly with smallholder coffee farmers and cooperatives in Mesoamerica as well as a variety of growers in Vermont. His research uses agroecology as a transdisciplinary, participatory, and action-oriented approach, focusing on the interactions among agriculture, food, farmer livelihoods, and environment. Most of his work utilizes a participatory action research (PAR) approach to directly support agroecological practice and farmer livelihoods.
