Abstract. Introduction to Biosystems Engineering is a coherent, dynamic educational resource targeted at 1st- and 2nd-year university-level students. The chapters stimulate interest and curiosity across the breadth of Biosystems Engineering and provide an international perspective. Faculty anywhere in the world can select interesting and engaging chapters of local relevance. This resource will grow over time with chapters contributed by Biosystems Engineers around the world. While the inaugural chapters are aligned with six ASABE technical communities, contributions of new chapters across the full scope of ASABE technical communities are very welcome. See the Biosystems Engineering Textbook and Digital Library home page ( for more details.

General areas and chapters as of June, 2021, include:
