The pie charts present information on the proportion of water utilized for six products and the revenue generated from each in 2004.
Overall, the vast majority of water was used for vegetables and fruits, whereas rice and dandelion used the least. Profit from these products largely reflected water usage, except for fruits and dandelion, which yielded higher profit margins. Fruits and rice, on the other hand, generated less revenue relative to their water usage.
Turning to details, fruits and vegetables were responsible for more than 70 percent of water usage, the latter accounting for 46 percent, which was higher than four other products combined. Among those 4 products, the largest contribution was made by cereal (12 percent) followed by lime (8 percent). The remaining 2 products, however, made up only 3 percent each.
With regards to revenue from all of these products, cereal and lime justified their water consumption. Similarly, fruits and rice showed even higher profit margins, at 40 percent and 8 percent respectively. Vegetables and rice, on the other hand, yielded lower returns. The former generated 31 percent of revenue compared to 46 percent water usage, while the latter generated only 1 percent as opposed to 3 percent water usage.
