The provided line graph illustrates global water consumption across agricultural, industrial, and domestic sectors between 1900 and 2000, while the table presents water usage data for Brazil and the Democratic Republic of Congo in the year 2000. Overall, global water consumption experienced a substantial rise over the century, with agriculture consistently accounting for the vast majority of usage. A significant disparity in water consumption per person and irrigated land is also evident between Brazil and the Democratic Republic of Congo in 2000. According to the graph, water consumption in all three sectors increased steadily throughout the period. Agricultural water use, which commenced at approximately 500 Km³ in 1900, soared to around 3,000 Km³ by 2000, maintaining its position as the primary consumer. Industrial consumption, initially a mere 50 Km³, showed a considerable rise to roughly 1,200 Km³ by the end of the century. In contrast, domestic water use remained the lowest, increasing from about 25 Km³ to around 400 Km³ over the same hundred years, demonstrating the least dramatic expansion among the sectors. Turning to the table, a striking contrast is observable between Brazil and the Democratic Republic of Congo in 2000. Brazil had a significantly larger population of 176 million, dwarfing that of the Democratic Republic of Congo at 5.2 million. This difference is mirrored in the extent of irrigated land, with Brazil utilizing 26,500 km² compared to the mere 100 km² in the Democratic Republic of Congo. Consequently, Brazil’s water consumption per person was substantially higher, at 359 m³, a stark difference when set against the Democratic Republic of Congo’s 8 m³.
