How is water used in food production?

To produce food, water is consumed by the plants in the field through evaporation and transpiration. The amount of water needed varies with crops and depends from place to place, on local productivity and conditions of available water supply through rainfall or irrigation.

Plants are about 80-95% water and need water for multiple reasons as they grow including for photosynthesis, for cooling, and to transport minerals and nutrients from the soil and into the plant. “We can grow food without fossil fuels, but we cannot grow food without water.”
