The observed variation in year-to-year annual rainfall at the four
locations is critical in determining future yields in Australian rainfed
broadacre crops, as demonstrated by data summarised in Fig. 6 and
reported by van Ittersum et al. (2003); Turner (2004); ABARES (2011,
2013). Interestingly, despite substantial decreases in mean rainfall,
the bias corrected downscaled data projected to 2030, 2060 and
2090 show broadly similar coefficient of variation values compared
to baseline (1961–2010)
