There are some communities that have proof of concept food foreststo inspire farmers to adopt them. This one in the KC Metro is a half acre. It may not be all-the-way scalable to the acreage of farms but the sustainability and fewer work hours to provide yields is hopefully appealing enough to have them adopted on some of the acreage they own.
