The given charts illustrate the distribution of water over the world and the usage of water in three nations, namely Egypt, Saudi Arabia, and Canada.
Overall, salt water dominates fresh water regarding all water in the world, while the proportion of water from ice and glaciers makes up the largest portion of all fresh water. In addition, most of the mentioned countries spend the largest amount of water on agriculture, except for Canada.
In the first two graphs, they report the distribution of water in the world. In particular, 97% of water in the world is salt water, compared to 3% that is drinkable water. In terms of fresh water, 79% of all fresh water stems from ice and glaciers, nearly quadrupling the figure for ground water. Meanwhile, only 1% of it is surface water.
With regard to the utilisation of water in the given nations, Egypt shares the water allocation with Saudi Arabia. Specifically, Egypt and Saudi Arabia spend up to 80% and 79% of their water on agriculture respectively. Additionally, both of them spend the same amount of water on domestic activities (at around 15%), in comparison with only around 10% allocated to industry in Egypt and 13% used for industry in Saudi Arabia. Conversely, Canada spends most of its water on industry (around 79%), more than five times as much as that of household activities and cultivation.
