AbstractThis study estimates the benefits from adopting Bt cotton seeds in Punjab, Pakistan over two cropping seasons - 2008 and 2009. The study uses the panel modeling approach to determine the average effects of Bt cotton technology on short-run profits, yields and farm inputs. This approach controls for biases resulting from self-selection and endogenous farm inputs. The study shows that, on average, Bt adopting farmers receive 9 per cent higher yields per hectare (ha), reduce per-ha pesticide use by 21.7 per cent, and increase per-ha use of irrigation water by 6 per cent. Our estimates of the increase in cotton yield are far below estimates from previous studies conducted in Pakistan and India, which do not use panel methods. Allowing more Bt cotton varieties and ensuring the availability of quality Bt cotton seeds in the market is likely to lead to further increase in the private benefits from Bt cotton.

Systems Simulation

The use of systems simulation modelling to predict crop loss and cost/effectiveness of pesticide use may reduce the need for schedule spraying of crops as an “insurance policy” against disease. The barley leaf rust (Puccinia hordei) model described here will form part of an information system designed to provide rapid feedback of information on disease development which the farmer can then use to assess benefits to be expected from spraying as opposed to the costs of application.
