    摘要:

    本文概述了作物生物技术对全球农业产生的经济和环境影响。分析结果表明,在农场水平上生物技术的应用产生了非常显著的净经济收益,2012年总计达到188亿美元,从1996年到2012年的17年间共计达到1 166亿美元,这些经济收益为发展中国家和发达国家的农民的经济收入增长各贡献了大约50%。转基因技术也对全球四大农作物的生产水平提高作出了重要的贡献。自从1990年中期采用这种技术之后,大豆和玉米的世界产量分别增加了1.22亿t和2.3亿t。在关键的环境影响因素方面,这种技术的应用减少了5.03亿 kg杀虫剂的用量(降低了8.8%),将使用除草剂和杀虫剂对环境的影响(基于环境影响指数EIQ衡量)降低了18.7%。这种技术也显著降低了农业地区温室气体的排放,在2012年减少的排放量相当于马路上的汽车减少了1 188万辆。

    Abstract:

    This paper summarises the economic and key environmental impacts that crop biotechnology has had on global agriculture.The analysis shows that there have been very significant net economic benefits at the farm level amounting to $18.8 billion in 2012 and $116.6 billion for the seventeen year period 1996-2012 (in nominal terms).These economic gains have been divided roughly 50% each to farmers in developed and developing countries.GM technology have also made important contributions to increasing global production levels of the four main crops,having added 122 million tonnes and 230 million tonnes respectively,to the global production of soybeans and maize since the introduction of the technology in the mid 1990s.In terms of key environmental impacts,the adoption of the technology has reduced pesticide spraying by 503 million kg (-8.8%) 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 18.7%.The technology has also facilitated a significant reduction in the release of greenhouse gas emissions from this cropping area,which,in 2012,was equivalent to removing 11.88 million cars from the roads.
