  8. 8. Why Gap Analysis? • CG collections suffer from both over- and under- collecting • Duplications increase costs • But also significant gaps in the collections
  9. 9. Why Gap Analysis? • Tool to assess crop genetic and geographical diversity. • Allows detecting non-fulfilled species collections as well as defining which species should be collected and where these collections should be focused. • Assesses the current extent at which the ex situ conservation system is correctly holding the genetic diversity of a particular genepool.
