The pie charts compare the proportion of water used for various purposes in six regions of the world.
In general, it is evident that North American and European people use water primarily for industry while the rest of the world spends it for agriculture.
Looking at more details, Central Asia and Africa make the most of the water for agriculture, with 88% and 84% respectively. However, these two regions see an opposite trend in using water for an industry which only accounts for 5% (Central Asia) and 7% (Africa). On the other hand, a great amount of water mainly used for the industry can be seen in North America and Europe, with 48% for the former and 53% for the latter.
Of all the six areas, South America is the only region that spends nearly a fifth of total water usage for domestication, followed by Europe (15%) and North America (13%). The minimum usage of water for domestication can be seen in South East Asia and Central, with both only accounts for 7% of total water usage.
