Agriculture uses 68% of the world's freshwater.
In terms of both consumptive and nonconsumptive use,
agriculture uses 68% of the freshwater from rivers, lakes, and groundwater.
Domestic and industrial use comes in at 19%, power at 10%, and evaporation from reservoirs at 3%.
This number is significant for many reasons.
Firstly, improvements in agriculture are going to be necessary as the global population grows,
not simply in terms of food produced, but in water used.
Creating more efficient means of irrigation will have significant impacts on the global water supply.
In addition, agriculture is a huge source of water pollution,
with 49 US states pointing to nitrates originating from agriculture as one of their major water pollutants.
All over the world, people are looking for fresh new ideas, even digging up some old ones.
