The pie charts illustrates the proportion of water used in America(North and South), Europe, Africa and Asia(Central and South East) for industrial, agricultural and domestic purposes.
Overall, it can be easily noticed that for the majority of areas, the percentage of water used for agriculture is the highest, with the exception of North America and Europe. In contrast, the proportion of water used for home purposes is the lowest in all zones.
While for North America roughly half of the water is used for industry compared to agriculture with approximately 40 percents, for South America the pattern is opposite with more water being used for agriculture(71%) and marginal 10 percents being spent for industry. The smallest amount of water used for agriculture, which is about one third, is in Europe. However, the portion of water used in households is more or less the same in all North America, South America and Europe(13, 19 and 15 respectively)
As for Africa, Central and South East Asia, patterns are quite similar. The majority of water is used on agriculture(84, 88 and 81 accordingly). In both Central and South East Asia only 7 percents of all water are used for domestic purposes. However, whereas in Central Asia only 5 percents are used in industry, for South East Asia this percentage is more than twice as high. In terms of Africa, there are minor differences with Asia: around 10 percents for domestic use and 7 for industrial.
