The water footprint

La huella hídrica es el volumen total de agua utilizado para producir un producto o un servicio consumidos por un individuo o comunidad.

According to the United Nations, mankind consumes half the water resources available in practice. But this use is not homogeneous. The water footprint is a way of measuring this consumption by regions or countries of the world.

In water consumption, climatic parameters are also involved, such as evapotranspiration, which is water that plants lose as a result of heat. Number of months of a year with water shortage

The map shows the number of months per year with water scarcity, ie, where evapotranspiration exceeds rainfall.
