This study assesses the economic and environmental impacts that have arisen from the adoption and use of genetically modified (GM) herbicide tolerant (HT) and insect resistant (IR) soybeans in South America in the five years since first planted in 2013/14. A total of 73.6 million hectares have been planted to soybeans containing these traits since 2013/14, with farmers benefiting from an increase in income of $7.64 billion. For every extra $1 spent on this seed relative to conventional seed, farmers have gained an additional $3.88 in extra income. These income gains have arisen from a combination of higher yields (+ 9.2% across the four countries using the technology) and lower costs of weed and pest control. The seed technology has reduced pesticide spraying by 10.44 million kg (-15.1%) and, as a result, decreased the environmental impact associated with herbicide and insecticide use on these crops (as measured by the indicator, the Environmental Impact Quotient (EIQ)) by 30.6%. The technology has also facilitated important cuts in fuel use and tillage changes, resulting in a significant reduction in the release of greenhouse gas emissions from the GM cropping area. In 2017/18, this was equivalent to removing 3.3 million cars from the roads.

Intacta 大豆对南美洲农场层面的经济和环境贡献：前五年。


本研究评估了南美洲自 2013/2014 年首次种植以来五年内采用和使用转基因 (GM) 耐除草剂 (HT) 和抗虫 (IR) 大豆所产生的经济和环境影响。自2013/2014年以来，共有7360万公顷的土地种植了含有这些性状的大豆，农民的收入增加了76.4亿美元。相对于传统种子，在这种种子上每多花 1 美元，农民就能额外获得 3.88 美元的额外收入。这些收入增长源于更高的产量（使用该技术的四个国家的产量增加了 9.2%）和更低的杂草和害虫防治成本。种子技术减少了农药喷洒量 1044 万公斤（-15.1%），从而减少了与这些作物使用除草剂和杀虫剂相关的环境影响（通过环境影响商数 (EIQ) 指标衡量） 30.6%。该技术还促进了燃料使用和耕作方式的大幅削减，从而显着减少了转基因种植区的温室气体排放。 2017/18 年，这相当于道路上减少了 330 万辆汽车。
