The line graph demonstrates the amount of global water use in three sectors measured by cubic kilometres between 1900 and 2000, while the table compares the water consumption of Brazil and Congo in 2000. Overall, an upward trend was recorded in all categories throughout the surveyed period. In addition, Brazil consumed substantially more water than Congo in 2000.
Looking at the line graph, it can be seen that water was mostly used in agricultural activities; to be more specific, the amount of water initially stood at around 500 before soaring to above 3000 in the final year. Notably, water was not used in industrial and domestic sectors from 1900 to 1920. Then, the figure for industrial use surged to approximately 1100 in 2000, exceeding nearly 300 of domestic activities at the same time.
Concerning the table, the population in Brazil in 2000 was 176 million people, significantly higher than 5.2 million in Congo. Moreover, the amount of water consumed per person in Brazil in 2000 was 359 cubic metres, with 26,500 square kilometres of irrigated land. Meanwhile, in Congo, only 100 square kilometres was used for irrigation, followed by only 8 cubic metres consumed per person in this country.
