Now look at the shape and spread of the curves for each of the countries, which tells us about the year-to-year variability of the yields. For all four countries, the yield in the present day has variability around the meansome years are expected to be better than average, some worse. How does this variability change in the future? For all countries, in the future scenarios, the variability (the range of yields, or the difference between a good growing year and a bad year) is expected to [ Select ] . This change in variability affects farmers, who rely on stable crop yields for a stable income
