Until the 1960s, there were fewer than half the number of people on the planet as of 2024. People were not as wealthy as today, consumed fewer calories and ate less meat, so less water was needed to produce their food. They required a third of the volume of water humans presently take from rivers.

In the US, some 80% of the fresh water withdrawn from rivers and groundwater is used to produce food and other agricultural products. [1] Farm water may include water used in the irrigation of crops or the watering of livestock. Its study is called agricultural hydrology. Water is one of the most fundamental parts of the global economy.
Greenhouses allow for greater crop production and also use less water since they are closed systems. [84] Desalination techniques can turn salt water into fresh water which allows greater access to water for areas with a limited supply. [85] This allows the irrigation of crops without decreasing natural fresh water sources. [86]
Alternate wetting and drying (AWD) is a water management technique, practiced to cultivate irrigated lowland rice with much less water than the usual system of maintaining continuous standing water in the crop field. It is a method of controlled and intermittent irrigation.
In the 1894-1895 season, Florida’s citrus crops were largely destroyed from a devastating freeze prompting growers to move farther south. By 1950, more than 100 million boxes of citrus were ...
Crop water productivity (WP) or water use efficiency (WUE) [5] expressed in kg/m³ is an efficiency term, expressing the amount of marketable product (e.g. kilograms of grain) in relation to the amount of input needed to produce that output (cubic meters of water). The water used for crop production is referred to as crop evapotranspiration.
