Over the last 25 years, genetically modified crops significantly improved farmers’ productivity while reducing their environmental footprint, offering an essential tool for feeding the world sustainably, shows a study released Wednesday.
The key finding: Crop biotechnology enabled an increase in global food, feed, and fiber production of nearly 1 billion tons between 1996-2020, with an environmental footprint decrease of 17.3% thanks to a 748.6 million kilogram reduction in use of crop protection products like insecticides, according to the study from PG Economics.
Greenhouse gas reduction: Because biotech-enhanced crops can be grown more sustainably, for example with less tilling, fossil fuel use declined during 1996-2020, reducing carbon emissions by 39.1 billion kilograms (43 million tons), or the equivalent of removing 25.9 million cars from the roads, the report says.
Financial benefits to farmers included large increases for those in developing countries—$5.22 for each dollar invested in genetically modified seeds during 1996-2020—and a global farm income benefit of $261.3 billion during that period. And making land more productive means less new land needs to be cultivated for agriculture.
Biotech helps to ensure food security sustainably. “Increasing food security involves not only growing more food and improving crop nutrition but also quickly breeding crops to thrive under changing weather patterns,” says an opinion piece in Foreign Policy last month arguing for passage of the UK’s Genetic Technology Bill. The bill would make it easier for researchers to test-grow gene-edited crops.
Regulatory improvements to help unlock the benefits of biotechnology for agriculture are also needed in the United States, and are proposed under the new executive order advancing biotechnology biomanufacturing. BIO outlined specific improvements needed in a recent letter to the administration.
