The chart below gives information about the production of grains, measured in million metric tons, from the years 2010 to 2015, with projections until 2030.

The table illustrates the amount of wheat, barley,

maize

and rice produced between 2010 and the present day, it

also

includes estimations till 2030. Units are measured in

million

metric

tons

.

Overall

, the

production

of all the grains grew from 2010 to the present day and is predicted to grow until 2030. The most significant changes can be observed in the

production

of barley

whereas

the manufacture of

maize

marginally increased. With regard to barley, it was the second most produced grain at 50

million

metric

tons

in 2010.

This

figure increased by 30

million

metric

tons

in 2020 and is projected to increase two-fold the original amount by the final year. Moving ahead, the

production

of wheat in 2010 was at 100

million

metric

tons

making it the most produced grain. In 2020, the

production

of wheat increased to 107

million

metric

tons

and it is estimated that

this

manufacture will rise to 110 metric

tons

by 2030. Analysing the graph

further

, the manufacture of

maize

and rice stood at 34 and 24.7

million

metric

tons

respectively and increased by 0.5

million

metric

tons

each in 2020. It is forecasted that the figures for

maize

will be 35

million

metric

tons

and for rice it is estimated to reach 25.5

million

metric

tons

in 2030.
