The line graph and table illustrate the data on water use worldwide and water consumption in Brazil and the Democratic Republic of Congo. Overall, global industries’ water use significantly increased over the period, and Brazil consumed much more water than Congo in 2000.
Looking at the line graph, Agricultural water consumption saw a sharp increase from around 500 km³ in 1900 to nearly 3000 km³ in 2000. Similarly, industrial water use remained constantly low until around 1950, after which it grew considerably, reaching approximately 1200 km³ by 2000. Additionally, domestic water consumption followed an upward trend, although at a slower rate, rising drastically from around 50km³ in 1900 to roughly 500 km³ by the end of the period.
Turning to the table, it is evident that Brazil had a significantly larger population with 176 million people, than Democratic Republic of Congo with just 5.2 million people. Moreover, Brazil also had a vast amount of irrigated land, covering 26,500 km², whereas Congo only stretched over an area of 100 km². As a result, Brazil’s water utilization per person was remarkably higher at 359 m³, than the figure for Congo which was merely 8 m³.
