Indicator 6.4.1 “Change in water use efficiency over time”

Target 6.4 aims to increase water use efficiency across all sectors – this page explains why and how to monitor progress towards the target.

The indicator at a glance

Indicator 6.4.1 tracks the value added in US dollars per volume of water used in cubic meters, by a given economic activity over time. It considers water use by all economic activities, with a focus on agriculture, industry and the service sector.

The indicator allows countries to assess to what extent their economic growth depends on the use of their water resources. Regional differences in climate and water availability must be considered in the interpretation of this indicator, in particular for agriculture.

Data on water use will come from the records of the  national line ministries and institutions (e.g. for Water, Agriculture and Environment), and data on value generation in different sectors are commonly available from the National Statistical Office.

Why monitor water use efficiency?

Is national economic growth dependent on use of water resources? Data enables targeted interventions to sectors with high water use and low use efficiency.
