Adaptation options

• Impact of a 100mm more drought resistant bean in
  Africa
• Change in range with Ropt less 100mm
• Yellow Green areas show regions that will
  benefit from such a technology but where are
  the drought tolerant genes?

Loss of species richness in peanuts

Impact on species survival
16
Plant genetic resources conservation for
adaptability and transition

• Increasing importance of ex situ conservation
• Increasing importance of evolution and change in
  in situ conserved populations
• Increased importance of information availability,
  and accessibility and distribution of materials
