Changing patterns in genebank acquisitions of crop genetic materials: An analysis of global policy drivers and potential consequences
研究了1993年《生物多样性公约》和2004年《粮食和农业植物遗传资源国际条约》等全球政策变化如何影响基因库作物遗传材料的获取和国际交换，发现政策导致获取量下降，可能对粮食安全产生负面影响。
During the past two decades, a series of global policy changes affecting genetic resource conservation, use, and exchange have entered into force: the 2004 International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA), and more recently, the 2014 Nagoya Protocol on Access and Benefit Sharing (NP), a follow-on to the 1993 Convention on Biological Diversity (CBD). This paper characterizes the changing policy landscape governing international exchanges of plant genetic resources for food and agriculture (PGRFA). Emphasis is placed on understanding how global and national policy changes associated with the CBD and ITPGRFA are significantly associated with the movement of genetic resources to draw lessons about the potential effects of the NP. We examine crop-specific historical trends in genebank acquisitions, changes in germplasm exchange networks over time, and correlates of such exchanges for seven crops that are important to food security in many developing countries. We observe sharp declines in genebank acquisitions in 1993 (when the CBD came into effect) followed by reductions in germplasm exchange network sizes. These trends and patterns change after 2004 (when the ITPGRFA came into effect), but only for some crops. We also find that a country’s membership in the CBD is closely associated with reductions in genetic resource flows, while ITPGRFA membership has an opposite association. Despite important crop and country variations, results suggest the considerable influence of both the CBD and ITPGRFA, further suggesting that the NP may affect global PGRFA flows in a potentially negative and unintended manner.
