The charts compare the amount of water used for agriculture, industry and homes
around the world, and water use in Brazil and the Democratic Republic of Congo.
It is clear that global water needs rose significantly between 1900 and 2000, and that
agriculture accounted for the largest proportion of water used. We can also see that
water consumption was considerably higher in Brazil than in the Congo.
In 1900, around 500 km3 of water was used by the agriculture sector worldwide. The
figures for industrial and domestic water consumption stood at around one fifth of
that amount. By 2000, global water use for agriculture had increased to around 3,000
km3, industrial water use had risen to just under half that amount, and domestic
consumption had reached approximately 500 km3.
In the year 2000, the populations of Brazil and the Congo were 176 million and 5.2
million respectively. Water consumption per person in Brazil, at 359 m3, was much
higher than that in the Congo, at only 8 m3, and this could be explained by the fact
that Brazil had 265 times more irrigated land.
