Germplasm exchange is critical to conservation of biodiversity and global food security

Abstract

AbstractGlobal 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.
