The given line graph indicates the data of global water employed in three different sectors during a 100-year period starting from 1900 while the table demonstrates the amount of water used in two distinct nations in 2000.
Overall, one basic trend in the graph which could be recognised is upward. It is also highlighted that Agriculture accounted for most water and Brazil had the highest water consumption.
As regards the first, the figure of Agriculture uplifted significantly by roughly 2500 km and reached a peak at about 3000 km after a century. Additionally, a stability at approximately 100 km was witnessed in either the information of Industrial and Domestic between 1900 and 1940. After 60 years, water consumption for Industrial purpose rose moderately to above 1000 km, which was more than double to those data of Household use in the last year.
In 2000, the population of Brazil and Congo was 176 and 5.2 million respectively. Also, the former had an area of 26500 km for irrigation and a per capita water consumption of 359 m. In comparison, the corresponding figures of the latter were only 100 km and 8 m.
