The line graph illustrates global water use in three different sectors from 1900 to 2000, while the table shows comparison of water consumption in Brazil and the Domestic Republic of Congo in 2000.
Overall, water use increased in all three sectors during the period. The most usage of water was in Agriculture. In addition, Brazil had all three figures, included population, irrigated land, and water consumption per person, more than Congo.
In 1900, agriculture used about 500 km3 of water, while industrial and domestic rarely used of water. Agriculture water use increased slowly until 1940s and then rose rapidly, reaching approximately 3,000 km3 in 2000. Industrial water use also grew steadily to about 1,000 km3, whereas domestic use increased gradually to below 1,000 km3 by the end of the period.
According to the table, Brazil had a population of 176 million, compared with only 5.2 million in Congo. Brazil also had far more irrigated land, at 26,500 km2, while the Domestic Republic of Congo had just 100 km2. Furthermore, water consumption per person in Brazil was higher than Congo followed by 359 m3 and 8 m3 respectively.
