Global food security depends on the continual improvement of a relatively small number of food and feed crops. Today's food supply is heavily dependent on the movement of seed and other forms of plant germplasm for these crops across national and regional borders. As occurred during the Green Revolution, facilitated and widespread exchange of the major food crops is critical for food security. Plant breeders, molecular biologists, and agronomists, using scientifically guided processes and working collaboratively around the world, are achieving greater gains in crop yields and quality in shorter times than in the past. However, newer policies emerging from international environmental negotiations are giving rise to restrictions that are limiting access and exchange of germplasm and threatening food security. We argue that these evolving policies and practices are having far-reaching and negative impacts on plant breeding, agriculture, and food security. We provide some ideas on how to steer future policy negotiations to encourage germplasm exchange and thereby support food security and other important environmental objectives.

种质交换对于保护生物多样性和全球粮食安全至关重要

全球粮食安全取决于数量相对较少的粮食和饲料作物的持续改良。今天的粮食供应严重依赖于这些作物的种子和其他形式的植物种质跨越国家和地区边界的流动。正如绿色革命期间发生的那样,促进主要粮食作物的广泛交流对粮食安全至关重要。植物育种家、分子生物学家和农艺师使用科学指导的过程并在世界各地通力合作,正在比过去更短的时间内实现更大的作物产量和质量收益。然而,国际环境谈判中出现的新政策正在引起限制,限制了种质资源的获取和交换,并威胁到粮食安全。我们认为,这些不断发展的政策和做法正在对植物育种、农业和粮食安全产生深远的负面影响。我们提供了一些关于如何指导未来政策谈判以鼓励种质交换从而支持粮食安全和其他重要环境目标的想法。
