The graph and table below give information about water use worldwide and water consumption in two different countries.

The charts compare the amount of

water

used for

agriculture

, industry, and homes around the world between 1990 and 2000, and the

water

use in

Brazil

and

Congo

in 2000. Looking from an

overall

perspective, it is readily apparent that global

water

needs

increased

significantly over a period of 100 years, and

agriculture

made up the largest proportion of

water

used. It is

also

notable that

water

consumption was considerably higher in

Brazil

than in the

Congo

. A deep analysis of the charts provided reveals that in 1900, around 500 km3 was used by the

agriculture

sector,

while

the data for industrial usage and domestic usage stood at around one-fifth of that amount. By 2000, global

water

purpose for

agriculture

rose significantly, at around 3000 km3,

whereas

industrial purposes accounted for just under half that amount, and domestic consumption

also

saw a gradual growth to 500 km3. Looking at the charts in more detail, it can be seen that in the year 2000, the populations of

Brazil

and

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 Democratic Republic of

Congo

, at 8 m3.

Moreover

, the use of

water

for irrigated land in

Brazil

was 26.5 times higher than that in

Congo

, with 26.500 km3 and 100 km3 respectively.
