Service Description: Concentration of areas considered gaps in genebank collections for high priority species for the Yam Water (Dioscorea alata). Gap richness on the crop genepool level, i.e. the number of crop genepools that display gaps in any particular area. The genebank collections of the crop wild relative (CWR) are threatened in the wild by habitat modification, the modernization of agricultural areas, and invasive species, among other factors, and climate change is likely to exacerbate their vulnerability.
The gap analysis methodology relies on taxonomic, geographical, and environmental occurrence information, which is used to model the potential distribution of each CWR species of interest. Also includes an expert evaluation, in which researcher with knowledge of the conservation status and distribution of CWR in specific genepools are asked to analyze the gap analysis results. Furthermore results for multiple crop genepools may be overlaid, which allow a global analysis of gaps in ex situ collections of the world's plant genetic resources. The full results of the gap analysis can be found on the Crop Wild Relatives Global Atlas on the Adapting Agriculture to Climate project website
