Given are two graphs showing water use in the world by sectors and illustrating water consumption of Brazil and Congo.
It is obvious that global water demands had an upward trend throughout the century. Among the three purposes, the figure for agriculture accounted for the largest proportion in water use graph. Also, it is noticeable that water consumption was significantly higher in Brazil than Congo.
According to the line graph, the agriculture sector used the largest amouts of water in 1990, was about 500km^3, whereas the figures for industrial and domestic water maintained, at nearly 100km^3 from 1990 to 1940. However, the water use for agriculture rose dramatically to around 300km^3, while the industrial sector's consumption increased to just over 1000km^3 and domestic consumption reached around 300km^3. Finally the expenditure of agricultural purpose showed six times the figure for domestic use in 2000.
When it comes to the table, the amount of irrigated land in Brazil was 26,500km^3 with the population of 176 million, whereas 1000m^3 land was irrigated and there were 52 million people in Congo. Therefore, Brazilian consumed 265 times more water than Congo. |
