From these different pie chart graphs, we can compare and make the following comparisons and assumptions about water usage in different regions of the world.
First of all, we can see that the water usage repartitions in Central Asia, South eastern Asia, Africa and South america are fairly similar. This could be because of their position the south hemisphere. Or from their similar ground resources and opportunities.
Secondly we can observe that Europe and North america are practically the same, arguably also because of their position on the north hemisphere, ground resources and opportunities.
In the end, different regions of the world have similar water usage repartition because of their ground’s structure, their main soil’s occupation and industrial development.
