Yesterday I visited Tablehurst farm near here as part of a group organised by the Food academics group at the local universities. This is a community supported agriculture scheme run by a co-op of around 600 local people.
The organiser is active on the management team but in his day job is prof of land economy at the University of Brighton.
The relevance to this thread is that they got some money to do a research project into the motivation Ot the group. They chose to do this by involving one of the activists in creating an oral history.
