I "attended" an email conference a year ago sponsored by the FAO:
Learning from the past: Successes and failures with agricultural biotechnologies in developing countries over the last 20 years.
I really enjoyed it. The vast majority of "presentations" were given by scientists working in the developing world and the topics ranged through sustainability, biotech and appropriate technology.
They've published the official summary of it now and asked the attendees to distribute it, so here you go.
