Pesticide use increases from supposedly pesticide-decreasing GM crops – new scientific analysis
 An incisive new analysis from an international team of authors, including Glenn Davis Stone and K. R. Kranthi, finds that pesticide use increases from supposedly pesticide-decreasing GM crops. The paper states, “Genetically modified (GM) crops are a technology with the theoretical potential to make agriculture more efficient as a function of yield per input (e.g., water, fuel, fertiliser and pesticide) or unit of land. Like other technological efficiencies, however, the increased use of GM crops over the past 30 years has not contributed to input reductions nor to land reclamations, but to the expansion of agricultural land and increased use of the very pesticides these technologies are purported to curtail. Here, we present a global analysis of Herbicide Tolerant crops and an empirical case study from Bacillus thuringiensis (Bt) cotton in India. In lowering the costs for pesticide applications at the farm level, GM crops not only induce greater overall consumption of those pesticides but also help to sustain this larger system of chemical-intensive monoculture.” The paper adds, “Though promoted with the potential to reduce agrichemical applications, purporting to make the system less costly, dangerous and environmentally destructive, their [GM crops’] aggregate adoption and subsequent normalisation has had the opposite effect of spurring ever-greater agrichemical use.” |
