The given line graph present information about global water use by sector from 1900 to 2000, while the table illustrates water consumption in countries, namely Brazil and Congo in 2000.
Overall, agriculture, industrial use, and domestic use showed an upward trend throughout the period. Regarding two countries, Brazil consumed more amount of water than Congo.
Moving to a more detailed analysis, at the beginning of the period agriculture used approximately 500 km cubes, while the figures for industrial and domestic consumption stood at round one fifth of that amount. At the end of the period, 2000 experienced a significant growth in the amount of water consumption. Additionally, there was a noticeable increase in the agricultural water use by roughly 2500 km cubes, whereas the figures for industrial and domestic uses rose to slightly above 1000 and 300 km cubes, respectively.
In terms of water consumption by countries, 176 million Brazil people consumed 359 m cubes per person, while Congo with 5.2 million population used 8 m cubes per person. That huge gap could be explained not only by the difference between populations, but also by a significant difference between areas. While Brazil owns 26,500 km squares, the Congo’s territory is only about 100 km squares.
