A recent report by the United States Department of Agriculture (USDA) Foreign Agricultural Service welcoming the Government of Ethiopia’s (GOE) approval of commercial cultivation of genetically modified (GM) cotton and confined field trail on GM maize has ignited a public debate over deployment of GM seeds.

Proponents of GM argue that adoption can lead to increased yields, decreased insecticide applications, reduced drudgery, and the use of environmentally friendly herbicides.
…[A] meta-study published in 2014 estimates a 22% increase in global yield from GM crops while reducing pesticide …. usage by 37% and environmental impact (insecticide and herbicide use) by 18%. For countries with foreign currency bottlenecks like Ethiopia, reduced usage of inputs such as pesticide, insecticide, and herbicide translate to substantial foreign currency savings.
An additional misconception that should be untangled from the ongoing conversation is one that alludes to [Ethiopia’s] approval of a GM crop as a “breakaway” position from an “African consensus” on the ban against GM …. GM crops have been commercially cultivated in Africa since as early as 1998. Commercial cultivation in South Africa begun in 1998 reaching 2.1 million hectares of land covered with biotech maize, including Bt maize, by 2014.
Burkina Faso and Egypt followed in 2008. Sudan initiated commercial GM cotton in 2012 and by the end of 2018 had 0.2 million hectares of land covered with biotech crops, a significant part of which was Bt cotton. Other African countries were conducting trials on GM crops with approvals for commercial cultivation widely expected soon. Kenya, for instance, had already approved field trials for Bt maize back in 2016. In 2019, the Kenyan government further granted approval for Bt cotton cultivation, in a move welcomed by its agricultural research community.
There appears to be a tendency to equate The Cartagena Protocol on Biosafety, adopted on 29th January 2000, as a consensus on a collective ban against GMOs. The Protocol is an international agreement which aims to ensure the safe handling, transport, and use of living modified organisms (LMOs) resulting from modern biotechnology on the precautionary principle (PP). Opponents often invoke the PP to justify a ban on GM, but proponents see these as selective applications of the PP.
