It isn’t just agricultural biodiversity that needs looking after; sometimes it is the agriculture itself. In my in-basket today two stories of farms saved for the future. Coincidence, I’m sure, but it is not hard to glean a single message of nostalgia combined with urban alienation from the rescue of College Farm in north London and Gellatly Nut Farm in British Columbia. I’ve often thought that we should make more of the commonalities between developed and developing countries than we do. Maybe these stories will help.
