Though studies after studies are being brought out by the biotech proponents and industry, claiming that they have findings to show that Bt technology has improved cotton yields in India, and therefore net returns of farmers (increase that more than makes up for the increased cost of cultivation, is the claim) and from those net returns, everything from women's empowerment to better quality education is being claimed, nobody has been able to give a convincing answer to a fairly common sensical question, based on something that everyone accepts – that bollworm incidence itself has been low since 2002 – if pest pressure is low, how did the Bt technology end up contributing to yield increases?
