Sensitive Dependencies and Separation Distances for Genetically Modified Herbicide-Tolerant Crops

Abstract

The amount of land available for the coexistent growing of both organic and genetically modified herbicide-tolerant (GMHT) crops depends on the separation distance between the two types of crop. The form of the decline in the proportion of land available for growing one of these crop types due to increasing separation distance is linear on a suitable scale, but with a slope and intercept that are sensitively dependent on the proportion of the other crop already present. Spatially explicit simulations from realistic scenarios indicate that a major increase in separation distances, currently under review by the UK government, may have serious implications for the future coexistence of organic and GMHT crops in the UK.
