EcoSummit 2012, which starts on Sept. 30 in Columbus, includes a number of field trips for the delegates, who will have come here from 75 countries. This one features agricultural stability and food security and goes to two places that exemplify just that: the Richland County farm of a world-famous sustainable-agriculture pioneer (video, 7:21) … and 28 miles up the road, the Wooster campus of our very own OARDC (video, 2:00).
