Community of practice. FAO and the IAEA, through their ca. half a century partnership, is investing considerable resources in training, technology transfer, strengthening of infrastructure, provision of services and in research. To achieve the greatest impacts through engagements at scale, a critical mass of partners that are engaged in similar endeavors and whose activities complement those of this partnership need to be assembled. Such a community could arise around a theme, such as climate change, for instance. Induced mutations can unmask alleles of genes that can be introgressed into breeding materials. This would clearly complement several ongoing activities by a multitude of potential partners, even on global scales, but efforts need to be invested in coalescing these efforts. The TCP and CRP models of the Joint FAO/IAEA Division of Nuclear Techniques for Food and Agriculture can be further scaled up to achieve this purpose.
