On the 'Failure of Bt Cotton': Analysing a Decade of Experience

Given that the controversy over success and failure of Bt technology still exists, this paper discusses the available field studies that have addressed agro-economic questions of Bt cotton cultivation in India. Since a meta-analysis of studies can give only partial conclusions, owing to differences across study methodologies and coverage, this paper takes a different strategy, i e, looking not simply at differences between Bt farms and non-Bt farms, but at the experience of farmers before growing Bt and after switching to Bt. It also examines the more general problem of comparing field studies and suggests ways to use farmer behaviour as a proxy for settling different interpretations of agro-economic effects of the new technology. The study explains why there has been so much controversy given virtually universal adoption of Bt technology in cotton and concludes that in the battle of numbers around Bt cotton, those of the farmers have been curiously missing.
