At 4 p.m. next Sunday, Central Congregational Church will welcome Erin Stack, owner and manager of New Harmony Farm in West Newbury, for a discussion about organic farming. Her talk, “Can Organic Farming Save the World?,” will explore the farm’s model of regenerative agriculture, which focuses on organic, biological, and permaculture farming practices, as well as ecology education and research. Stack is the founder of the Green Artists League and developer of the New Eden Collaborative Community Gardens of First Parish Church in Newbury. Immediately following Stack’s presentation, the church will host a local flavor community potluck dinner. Participants are asked to bring a potluck dish that features locally sourced ingredients and nondisposable eating utensils, plates, and napkins. This event is free and open to the public; all ages are welcome to attend. Stack’s talk and the potluck dinner are being cosponsored by Transition Newburyport, which is dedicated to building community resilience in challenging times, and Community Resilience Circles, a small support group that strives to help people enhance their personal security through education, mutual aid, and community support. Central Congregational Church is located at 14 Titcomb St. For more information, visit www.transitionnewburyport.org or call 978-462-1308.
