Philip Ackerman-Leist, farmer, author and Green Mountain College associate professor, will present "Rebuilding the Foodshed: Remapping Our Expectations for the Food We Share," a lecture on local food systems at 7 p.m. Tuesday, April 30, in room 206 of the Valders Hall of Science on the Luther College campus.

A signing session with Ackerman-Leist will follow the lecture.

Both the lecture and the book signing are open to the public with no charge for admission.

The lecture focuses on the complexities involved in building a stable, community-based foodshed. According to Ackerman-Leist, in order to create a lasting system, foodsheds need in-depth planning and consideration, keeping in mind the unique needs of the people they service. Models proposed for these systems are meant to transform how we grow, purchase and eat our food. Ackerman-Leist explores food production on a local scale and proposes strategies for creating more democratic and secure food systems.

Ackerman-Leist serves as both an associate professor of environmental studies and the director of the Farm and Food Project at Green Mountain College in Poultney, Vt. He also established the college's farm and sustainable agriculture curriculum.

He has published two books: "Rebuilding the Foodshed: How to Create Local, Sustainable and Secure Food Systems," an in-depth examination of how to craft a community-based food system, and "Up Tunket Road: The Education of a Modern Homesteader," a narrative that examines the role of the modern homesteader.

Ackerman-Leist and his wife, Erin, are currently involved in a homesteading and farming venture in Pawlet, Vt.
