The line graph illustrates three sectors in terms of the amount of water that they used in the world between 1900 and 2000, while the table gives information about water expenditure in two countries ( Brazil and Congo) in 2000. Units are measured in km³ and m³ respectively.
Overall, the global water rose significantly in each sector over the period given, although the highest water used by the agriculture sector, the lowest used was domestic. It could be seen that water consumption was considerably higher in Brazil than in Congo.
In 1900, around 500km³ of water was used by the agriculture sector worldwide. The figures
for industrial and domestic water consumption stood at around one fifth of that amount. By 2000, global water use for the agriculture sector reached almost 3000km³, industrial water use increased to just over 1000km³, and domestic use rose to approximately 400km³.
In 2000, the population of Brazil was overwhelmingly more than Congo. Furthermore, water consumption per person in Brazil, at 359m³, was much higher than in Congo, at 8 m³, and it is clear that there was a significant difference by the fact that Brazil had 265 times more irrigated land.
