A new study on the introduction of Bt cotton in Vidarbha reveals that it has failed in the region. Suman Sahai, Director of Gene Campaign, told journalists on Wednesday that despite specific knowledge that Bt cotton would not work in rainfed areas, the government had introduced it in Vidarbha. The result was that in an area with a history of indebtedness, the high input costs of Bt cotton had increased indebtedness. The study had shown that 70 per cent of small farmers had already lost their landholdings as collateral for loans that they could never repay.
