Figure 12 illustrates the yield effects in the OECD when each of the five R&D and water management adaptation scenarios are combined with the Reference scenario and with each of the four climate change yield scenarios discussed in Section 3 (the Alternative SSP scenario is not included). The largest price decreases for any specific commodity occurs in the R&D scenarios, which assume increases in maize and wheat yields. The price for maize decreases by more than 4% in the technology transfer scenario.
