Seth Denizen, an assistant professor of architecture, and Montserrat Bonvehi Rosich, a visiting assistant professor of architecture, both at the WashU Sam Fox School, have won the 2026 John Brinckerhoff Jackson Book Prize for “Thinking Through Soil: Wastewater Agriculture in the Mezquital Valley.”

Coordinated by the University of Virginia (UVA), the juried prize recognizes outstanding scholarship that breaks new ground on a subject in landscape studies. “Thinking Through Soil,” published last year by Harvard Design Press, explores the largest wastewater agricultural system in the world, centering soil as a way to examine complex environmental challenges.
Jury chair Elizabeth K.
