The line graph presents
how much water was used by three main sectors in the world in the
century whereas the table provided shows how much water was consumed in two
different countries.
As is presented in the chart, the trend movement of water use
can be divided into three distinct periods: from 1900 to 1940, from 1941 to
1950, and from 1951 to 2000. The period between 1900 and 1940, water use by
agriculture sector increased gradually while in contrast, industrial and
domestic use remained unchanged. Thereafter, the trend movement varied from
1941 to 1950 which agriculture use continued to have an upward trend, followed
by the gradual rise in industrial use but unlike the other sectors, water use
by domestic was still static over the period. In the last period, all sectors
rose significantly which domestic use had the least significant increase
throughout the period. In addition, the highest position was reached by agriculture, industry and domestic in the year 2000 with about 3,000 Km3,
1,200 Km3 and 300 Km3 consecutively.
Turning to the table, it can be seen that there is an extreme
gap between the amount of water consumption per person in Brazil and the
amount of water consumption per person in Democratic Republic of Congo. With a
population of 5.2 million and only 100 Km2 irrigated land, the
average amount of water which is consumed by a person in the Congo is just
merely 8 m3, a small amount compared to Brazil which every person
consumes water with 359 m3.
