Over the next two decades, Asia experienced a steady decline, falling to 30% in 1980. During the period from 1960 to 2000, there was an increase in Asia’s share of production from 30% to 35%.
in 1920 Europe accounted for 40% of the total wheat production, while rest of the world contributed only 10% during the same period. after that, Europe slightly and peaked at roughly 48% in 1920; nevertheless, it fell to nearly 28% in 2000. by contrast, in 1920 the rest of the world was 10% being lower than Europe by 30% after that, it jumped considerably to the highest mark, which was nearly the same as Europe, then it being higher than Europe by 5% at the end of the period
