Results also showthat there is a large variation in yields between
current and future climate conditions and across locations and crops
(Figs. 6 and 8) and this implies crop species have differing sensitivities
to climatic variations (Huntingford et al., 2005). For example, this
study suggests field peas are more sensitive to changes in climate,
than cereals or canola. The ensemblemedian changes in field pea yield
range from at least a decrease of 12% in 2030 to up to a decrease of
45% in 2090. In contrast, the ensemble median changes in wheat yield
range from at least a decrease of 5% in 2030 to up to a decrease of
30% in 2090. However, when viewed froma national perspective, the
disproportionally larger impact of climate change on the yield of field
peas is likely to be less economically significant than the impact on
cereals. This is due to the volume of field pea production only being
~1% of the combined volume of wheat, barley and canola in the last
five years (ABARES, 2013).
