Monitoring water use efficiency (indicator 6.4.1)
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, and what resources that are available for countries to do so
The indicator tracks the value added (US dollars) per volume of water withdrawn (cubic metres), by a given economic activity over time.
By reporting on trends in water-use efficiency, the indicator highlights to what extent a country’s economic growth is dependent on the use of water resources.
This indicator includes water use by all economic activities, with a focus on agriculture, industry and the service sector.
How to progressively monitor?
Data on water withdrawals will come from the monitoring of indicator 6.4.2 on water stress, and data on value generation in different sectors are commonly available from the NSO, which makes the monitoring of this indicator very cost-efficient.
