The image shows the number of water used worldwide (km3) divided into three different sectors, from 1910 to 2010. Overall, each sector experienced an increasing trend throughout the years. The agriculture sector was the highest, followed by industrial use in second place, and domestic use in third place. In addition, the positions were unchanged from the beginning to the end of the period.
In the first four decades, from 1910 to 1940, water use in the agriculture sector grew steadily from 500 to 580 km3. A decade later, the number jumped to 1,000 km3. After the number increased slightly by 20 km3 in 1960, five decades later, the number rose significantly, and the amount of water used for agriculture reached its peak at around 3,000 km3 in 2010.
Initially, the amounts of water used for industrial and domestic use were not far apart, with only a 10 km3 difference (20 km3 for industrial use and 10 km3 for domestic use). But, after growing steadily for six decades, in 1980, the amount of water used for industrial purposes had a massive increase, to around 500 km3, and continued increasing for the next three decades, reaching around 1,500 km3 in 2010. Meanwhile, the water used for domestic purposes grew steadily throughout the decades with only a noticeable jump in 1980. In 2010, the water used for domestic purposes peaked at 150 km3.
