The two diagrams show the global usage of water over the 20th century and compare water consumption in Brazil and Congo in the year of 2000 by populations, irrigated lands, and water consumption per capita.
From an overall perspective, it is evident from the line graph that the period of 1900 and 2000 witnessed a dramatic rise in the amount of water used globally. Noticeably, agriculture consumed the largest amount of water, while household use accounted for the smallest. Looking closer at the table, Brazil obviously used more water than Democratic Republic of Congo, as Brazil had more populated residents and irrigated lands in 2000.
With regard to the line graph, an increasing trend can be seen in the three sectors in the 20th century. The period of 1990 to 2000 witnessed a surge in the amount of water used for farming, increasing from 500 km3 in 1990 to 3000 km3 in 2000. The amount of water used in the industrial sector also grew by nearly 900 kms in 100 years, whereas water used in households gradually developed over the same period.
Regarding the table, it is clear that Brazil’s usage of water was superior to Congo’s, with 359 m3 and 8 m3 respectively. Its population and farming lands were also larger, with 176 million people and 26,500 km2 in comparison to 5,2 million people and 100 km2 in Congo.
