Colombia Benefits Economically and Environmentally from 15 Years of Planting GM CropsFebruary 12, 2020
A study conducted by Graham Brookes of PG Economics Ltd. published in the journal GM Crops and Food finds that since 2003, crop biotechnology has helped Colombian farmers grow more food, feed, and fiber, using fewer resources and farm incomes increased by a total of over US$300 million. Crop biotechnology has enabled Colombian farmers to obtain higher yields from better pest and weed control, reducing the environmental footprint associated with the production of cotton and maize.
The study finds that since 2003, about 1 million hectares of biotech cotton and biotech maize were planted in Colombia and in 2018, the technology was used on the equivalent of 90% and 36% respectively of the total cotton and (commercial) maize crops.
The extra production and reduced cost of pest and weed control helped maize farmers attain higher incomes equal to an average of US$294/ha and an average return on investment equal to +US$5.25 for each extra US$1 spent on GM maize seed relative to conventional seed. For cotton farmers, the average increase in income has been +US$358/ha, with an average return on investment equal to +US$3.09 for each extra US$1 spent on GM seed relative to conventional seed. The study also found that crop biotechnology facilitated cuts in fuel use, resulting in a reduction in the release of greenhouse gas emissions from the GM cotton and maize cropping area and contributed to saving scarce land resources.
