The pie charts compare the proportion of water used for three different objectives in six regions
Overall, the vast majority of water used in the world is for agriculture whilst water usage for domestic use is the lowest in most regions.
As can be seen from the charts, the most significant water usage in most regions is for agricultural needs, and the highest proportion is in Central Asia, at 88 per cent. It is followed by Africa, South East Asia, and South America respectively with a gap ranging from 3 to 10 per cent. Additionally, it is worth noticing that of the 4 regions mentioned before, South East Asia is the only region which has industrial use as the second highest purpose while other regions have the opposite.
North America and Europe have different patterns than the other four. Both of them used to utilize their water for industrial purposes at 48 per cent (North America) and 53 per cent (Europe). Additionally, water usage for agricultural needs in both regions appears to be the second highest at less than 40 per cent, while domestic use is the lowest, at only approximately 15 per cent.
