The given line graph illustrates global water expense over 10 years’ time period while the table compares the water utilized for land irrigation in Brazil and Congo in 2000. Overall, it is evident that water expenditure increased over the years for all the given sectors and water consumption in Brazil was much higher than that of Congo.
Getting back to the details, throughout the time period agriculture sector required the highest amount of water and this increased dramatically from 500 km2 in 1900 to 3000 km2 in 2000. The water requirement in the industrial and domestic area remained nearly the same and negligible until 1940, followed by a slight increase in the year 1960. After 1960, rise in water usage can be seen in both sectors with industrial sector surpassing the amount used compared to domestic. In the final year, the water utilization reached as much as 1000km2 for industrial while the usage remained below 500km2 for domestic purposes.
Brazil’s population was 35 folds more than Congo’s and its irrigated land was 26 times greater than Congo’s. Similarly, water spending per residents in Brazil was as high as 359m3 whereas Congo’s resident’s spending was limited to only 8m3.
