Introduction to Biosystems Engineering is designed as a coherent, dynamic educational resource targeted at 1st- and 2nd-year university-level students. It is designed as a coherent resource, also available for download as individual digital chapters. The chapters are intended to 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 How to Contribute a Chapter.

Development of this resource was supported by ASABE’s Harold Pinches and Glenn Schwab Teaching Materials Fund and Virginia Tech Publishing.
