Impact of climate change on European wheat (a-c), potato (d-f) and grass (g-i)
yields, expressed as percentage difference relative to current yields (2005) for the
year 2050 with climate change projected by the ukmo_hadcm3 climate model under
the A1 scenario taking into consideration climate change (a,d,g), climate change and elevated CO2 concentration (b,e,h) and climate change, elevated CO2 concentration
and technical progress (c,f,i). (Illustration based on data from Hermans et al., 2010; source: Supplementary data, Appendix C)
