The line graph and table below display information on water usage and consumption in two different nations.
Overall, all three sectors witnessed an increase throughout the period. Water consumption by agricultural means was by far the most, being followed industrial use, and finally followed by domestic means as the least used.
Water usage by agriculture displayed a significant increase throughout the period, starting with about 500km3 in 1900, climbing to a little over 2000 in 1980, before ending the period with around 3000 in 2000. Industrial use didn’t show any significant increase until 1960, starting the period with about 100, before witnessing a shift in 1960, and ultimately ending the period with a little over 1000km3 in 2000. Domestic use witnessed barely any changes until the year 1960, starting the timeframe with 0, before finishing with a little around 400km3 in 2000.
Brazil had by far a much larger population, irrigated land, and thus more water consumption per person than Congo. Brazil had a population of 176 million, irrigated land mass of 26,500km2, and water consumption per person of 359m3. Compared to that of Brazil, Congo had a much lower population of 5.2 million, therefore resulting in less irrigated land of 100km2 and water consumption of 8m3 per person.
