The pie charts compare the percentage of water usage and the amount of income earned from six products in 2004.
Overall, a significant percentage of water was used for vegetables and fruits which together contributed the largest share to total income, comparing with other products. In contrast, cereal and lime recorded equal figures in both categories, showing balanced proportion between water usage and income. Of particular note is that the amount of revenue from dandelion that consumed the lowest share of water similar to rice, was almost three times higher than the percentage of its water consumption, whereas the reverse was true for rice, which produced the least income despite using a relatively higher proportion of water.
Focusing first on vegetables and fruits, the largest percentage of water was used for vegetables (46%), which was 18 percentage points higher than fruits. Although fruits required 28% of water, followed by vegetables, they contributed the highest percentage of total income, accounting for 40% compared with only 31% earned from vegetables.
When it comes to cereal and lime, the percentages of water and income were moderately balanced between cereal and lime. In 2004, lime generated 8% of total revenue while consuming 8% of water, whereas cereal produced comparable outcome, contributing 12% of revenue after using 12% of water.
Meanwhile other remaining products – dandelion and rice – consumed the lowest percentage of water, despite giving three times higher outcomes. They both recorded the same amount of water consumption (3%), dandelion generated 8% income, while the least income (1%) was earned from rice.
