GM crops have once again come under the spotlight with the recent news that Burkina Faso will no longer be growing Bt cotton (a genetically modified cotton variety, which produces a pesticide to counter the insect pest bollworm). Originally an early adopter of the technology, Burkina Faso became one of the first African countries to develop and release, with Monsanto, crosses of local and Bt cotton crops in 2008. As one of Africa’s largest cotton producers, their adoption of GM technology was ground-breaking. And, at least for some time, successful, increasing cotton production, yields and profits while reducing the number of pesticide sprays needed. With some 140,000 smallholders cultivating Bt cotton, it was also seen to de driving rural development, the average Bt cotton farming family reaping 50% more profits than families growing conventional cotton.
So why the reversal? The lint quality of Bt cotton varieties is poor and, as such, results in economic losses for the Burkinabè cotton companies that market it. Since they provide all seeds and inputs to cotton farmers, they have the power to phase out Bt cotton growing in the industry, which will take place over the next two years. In this case while the technology was boosting production and reducing pesticide use, an unintended impact on lint quality has become too big a hurdle for cotton companies to overcome. Now questions are being asked as to whether the same is likely to happen in other locations and situations, perhaps as a side effect of a “narrow, trait specific approach to addressing agricultural development”.
Despite this news from Burkina Faso, the argument in support of GM crops has somewhat intensified, with a recent article from Tim Benton, Professor of Population Ecology, University of Leeds reasserting that GM crops are one of a myriad of technologies and practices that we will need to feed the world. Since growth in yields are no longer increasing fast enough to meet projected food demand, we will need to expand crop land by an estimated 42% by 2050. This has broader consequences for biodiversity and ecosystem services as well as for greenhouse gas emissions, of which those associated with farming and food are currently set to push us past the 1.5℃ temperature-rise target set in Paris in 2015.
As Professor Benton explains, to avoid food shortages or the broader impacts of agricultural expansion we must either reduce demand for food or increase supply. The latter is about employing more efficient forms of agriculture, better land management but also technology to raise yields. How much of this technology will be comprised of biotechnology or genetic modification is unknown.
Some would like to see this be zero – for genetic modification to have no role in shaping future food supply. But could this opinion and the campaigning of anti-GM groups be harmful to food security? The Information Technology and Innovation Foundation (ITIF), in their new report, estimates that “the current restrictive climate for agricultural biotech innovations could cost low- and lower- middle-income nations up to $1.5 trillion in foregone economic benefits through 2050”. They also calculate that due to regulations and export limits that prevent widespread adoption of biotechnology, the lack of access to biotech innovations in farming has cost African agricultural economies at least $2.5 billion between 2008 and 2013.
