Book excerpt: At a time when environmental humanities and sustainability studies are creating new opportunities for curricular innovation, this volume examines factors key to successful implementation of cross-curricular initiatives in language programs. Contributors discuss theoretical issues pertinent to combining sustainability studies with foreign languages, describe curricular models transferable to a range of instructional contexts, and introduce program structures supportive of teaching cultures and languages across the curriculum. Exploring the intersection of ecocritical theory, second language acquisition research, and disciplinary fields, these essays demonstrate ways in which progressive language departments are being reconceived as relevant and viable programs of cross-disciplinary studies. They provide an introduction to teaching sustainability and environmental humanities topics in language, literature, and culture courses as well as a wide range of resources for teachers and diverse stakeholders in areas related to foreign language education.
