The graph shows how the amount of water used worldwide changed between
1900 and 2000.

Throughout the century, the largest quantity of water was used for agricultural
Purposes, and this increased dramatically from about 500 km³ to around
3,000 km.3 in the year 2000. Water used in the industrial and domestic sectors
also increased, but consumption was minimal until mid-century. From 1950
onwards, industrial use grew steadily to just over 1,000 krrf, while domestic
use rose more slowly to only 300 km^, both far below the levels of consumption

by agriculture.

The table illustrates the differences in agriculture consumption in some areas
of the world by contrasting the amount of irrigated land in Brazil (26,500 km^)
with that in the D.R.C. (100 km²). This means that a huge amount of water is
used in agriculture in Brazil, and this is reflected in the figures for water
consumption per person: 359 m.3 compared with only 8    in the Congo. With a
population of 176 million, the figures for Brazil indicate how high agriculture
water consumption can be in some countries.
