The provided graph illustrates information about global water consumption divided into three main areas (Domestic use, Industrial use, and Agriculture) over the period from 1900 to 2000. Additionally, the table compares water use in Agriculture in Brazil and the Democratic Republic of Congo for the year 2000. Overall, all three areas showed an upward trend; meanwhile, the largest quantity of water was used for agricultural purposes, and in some areas of the world, Population and Irrigated land have a direct relationship to water consumption.
Throughout the century, the largest amount of water was used for farming, and this increased dramatically from 500 to around 3,000 km3 in the year 2000. Water used in the industrial and domestic sectors also increased, but consumption was minimal until mid-century. From 1950 onwards, industrial use grew steadily to just over 1,000, while domestic use rose more slowly to only 400.
Turning to the table, the data highlights the differences in agricultural consumption in some areas of the world. Brazil, with a population of 176 million and 26,500 km² of irrigated land, had a per-person consumption of 359 m³. In contrast, the D-R-C, with a much smaller population of 5.2 million and only 100 km² of irrigated land, had a minimal per-person consumption of just 8 m³
