The potential impact of genetically engineered (GE) crops on biodiversity has been a topic of interest both in general as well as specifically in the context of the Convention on Biological Diversity. In a recent review, I took a biodiversity lens to the substantial body of literature that exists on the potential impacts of GE crops on the environment, considering the impacts at three levels: the crop; farm; and landscape scales1. Overall, the review finds that currently commercialized GE crops have reduced the impacts of agriculture on biodiversity, through enhanced adoption of conservation tillage practices, reduction of insecticide use, and use of more environmentally benign herbicides. Increasing yields also alleviate pressure to convert additional land into agricultural use...
