@xavier your link was really interesting, the summary gives us an excellent outline of what to expect in the book, which I think is author Arnaud Kaba’s published thesis.
According to the South East Asia Multidisciplinary Journal,
“It deals with ‘fair trade’ as a recent model of production often idealized but also criticized as it has been sometimes used as a simple marketing tool by companies. Taking Dharmabari, a tea garden plantation located in Darjeeling as a case study, the objective is to study this specific management instrument and its social consequences.”
All I can say is to everyone, read the English summary! I wasn’t familiar with Dharmabari estate, but the book sounds promising! Wish it were in English somewhere?
