"Peak water" is a concept that refers to the point at which the availability of freshwater reaches its maximum rate of use, after which the production and availability decline. The idea is derived from "peak oil," which describes the point in time when the maximum extraction of petroleum is reached, leading to a terminal decline in production rates. Despite being a concept, there's no widespread consensus that "peak water" has been reached globally, though some regions experience significant water stress.
