The graph elucidates how much water was consumed by three distinct sectors globally, measured in km³, over a one-century period (from 1910 until 2010).
Overall, it can be seen that agriculture was a predominant sector in water usage along with domestic use as a least water consumption. Moreover, the general trend was for the consumption of water to increase in all sectors within the timeline.
To begin with, in 1910, agriculture showed its superiority over those of the other sectors in the amount of water usage as the highest consumption, accounting for 500 km³, twenty five times as much as those of industrial use and fifty times as much as those of domestic use. Furthermore, the figure for water consumption in agriculture grew with the amount rising from 500 to 580 km³ from 1910 to 1940, then climbing twice as much as the former number in 1950 and 1960. Finally, the amount of water used surged significantly, commencing at 1500 km³ in 1970 and hitting the high of 3000 km³, which was the maximum amount recorded shown on the chart, in the last period of 2010.
Turning to Industrial and Domestic use, the amount of water used in both sectors appeared to slightly increase, ranging from 10 to 150 km³ in 1910 to 1970, before reaching a more than threefold increase in 1980. Subsequently, the demand for water consumption inclined and peaked at 1500 and 150 km³ in 2010 for industrial and domestic use, respectively.
