Noted permaculture designer and teacher Dick Pierce will present a slide show and talk called An Introduction to Permaculture: Practical Sustainability on Thursday, April 17, at 5 p.m. at the Chilmark Public Library.

Permaculture, a movement begun in the 1970s, initially focused on soil management to promote agricultural sustainability. It has segued into a holistic approach to sustainable living.

The idea is this: develop ecologically suitable design systems for sustainable living in all parts of your existence.

Since its inception, permaculture has gained international attention and there are now hundreds of certified permaculture practitioners worldwide.

Dick Pierce is from Austin, Tex. His talk is appropriate for beginners and seasoned veterans. It aims to appeal to anyone interested in organic food gardens, green building, alternative energy, resource reuse, and living locally.

Mr. Pierce also will be available to answer questions about the nine-day permaculture design certificate course scheduled to take place on the Vineyard Sept. 10 to 18.

Admission is free for this event sponsored by the Friends of the Chilmark Free Public Library. All are welcome.
