Which activity utilizes the greatest proportion of water globally?

Agricultural use utilizes the greatest proportion of water globally, as it accounts for approximately 70% of freshwater extraction worldwide. This is due to the extensive water requirements needed for irrigation to grow crops, raise livestock, and support other agricultural practices. Agriculture relies heavily on water supply to ensure food security and support the growing human population, making it the largest consumer of water when compared to domestic and industrial uses.

Domestic use, which includes water for drinking, cooking, and sanitation, represents a smaller fraction of global water consumption. Though important, it does not match the volume of water needed for agricultural purposes. Industrial use also requires significant amounts of water, particularly for processes like cooling, cleaning, and as a solvent in manufacturing. However, it typically falls below agricultural use in terms of total consumption.

Mining requires water, mainly for mineral processing and controlling dust, but its overall water usage is substantially lower than that of agriculture. Thus, when considering the total global allocation of water resources, agricultural usage remains the predominant activity.
