This article explores how the discipline of Environmental History can enhance the coherency of East Asian Studies as a field that is defined by geographical scope and linguistic ability, while simultaneously addressing intra- and transregional currents of people, practices, ideas, and objects. Concurrently, it asks how schol-arship focused within East Asia can enrich the practice of Environmental History at local, regional, national, and global scales. The article is organized into four sections followed by a conclusion. The first section considers the nationally-focused synthetic works of Environmental History from which a broader picture of East Asia can be compiled. The following three sections examine different ways of clustering the practice of Environmental History within East Asia. These are: 1) early modern Sinograph texts on pharmacology and natural history; 2) cultural overlays in one locality over time; and 3) movement through space of objects alienated from their original context and people who bear culture-specific practices to different areas. The conclusion considers the challenges of training scholars in an interdisciplinary field with significant language demands.
