Without water, life would not have appeared on Earth some 3.8 billion years ago. Water, an essential element for life, “heritage of the nation” (article 1is of the law of January 3, 1992 on water), is obviously a constant concern of all times and all places. The total amount of water on Earth has been constant for more than 4 billion years: under the effect of the sun, the water evaporates, condenses in the atmosphere to form clouds and then falls back in the form of precipitation. , then flows, infiltrates, before resurfacing and evaporating once more: this is the water cycle.
There are many uses of water and it seemed essential to us to provide readers with a certain amount of data and statistics concerning these uses.
The data presented in this article come from several sources dependent on institutional bodies, private operators, etc. Great efforts have been made by various actors to produce reliable data, while often acknowledging the lack of basic figures. In addition, the final validation requires a lot of time in order to cross-check all the available information. This is the reason why it is not yet possible to have all the validated data for the current period, end of 2022.
