The indicators of water stress rely on the ratio of water withdrawal to hydrological availability, along with a variation factor to account for variability of precipitation.

Simply put, a “water footprint” is a numeric representation of water usage. Many types of water footprinting tools are available; each is designed to measure water usage in some capacity. Water usage can be measured many ways, so not all of the tools are the same, and each one serves a specific purpose. For example, some focus on volumetric measurements, others focus on quality parameters.
