Line and Table

The line graph shows changes in water use for the whole world over a one hundred year period, spilt between three different sectors, while the table looks at just two countries-Brazil and the Democratic Republic of Congo-for the year 2000.

Over the one-hundred-year period, it is obvious that all three water types of water use increased significantly, although none of them changed position. Throughout the whole period, agricultural purposes required more water than any other, beginning at about 500km³ and soaring to more than 3,000 km³ a century later. Industrial use was much lower, at about 100km³ in the year 1900, but also soared, finishing the period about 1,500km³. Domestic use required slightly less water than industrial use at the beginning of the period, but grew to use around 500km³ by the millennium.

In the year 2000, Brazil had population and area of irrigated land vastly larger that of the Domestic Republic of Congo. Similarly, the amount of water used per person was more than forty times greater than that of the D.R. Congo.
