I have been following Stone's writings for a few years (links to some of his work here and here. See also http://www.anthropology-news.org/index.php/2012/01/06/genetically-modified-crops/)but missed the recent posts in his blog due to a trip to India. Here is a recent post:
Bt Cotton, Remarkable Success, and Four Ugly Facts .
He also discusses BT brinjal controversy in the post Decide for Yourself in view of Manmohan Singh's remarks in February “Biotechnology has enormous potential and, in due course of time, we must make use of genetic engineering technologies to increase the productivity of our agriculture. But there are controversies. There are NGOs (non-governmental organizations), often funded from the United States and the Scandinavian countries, which are not fully appreciative of the development challenges that our country faces.”.
