What is the concept of "embedded water" used for?

The concept of "embedded water" refers to the volume of water that is used in the production of goods and services. This includes the water required for growing crops, manufacturing products, and all the processes involved from extraction to production. By assessing embedded water, we can gain insights into the environmental impact associated with producing specific items. This is essential for understanding how much water is indirectly consumed through everyday products such as food, textiles, and electronics, which helps in making informed decisions regarding sustainability and resource management.

Considering the context of the other options, estimating water consumption of homes is more direct and does not take into account the broader supply chain, while determining water rights involves legal frameworks rather than production impacts. Measuring annual water usage is also a more straightforward assessment, focusing solely on direct consumption rather than the complex interrelations and impacts involved in production processes. Thus, embedded water allows for a comprehensive understanding of water use within the lifecycle of products, highlighting the importance of responsible consumption and production practices.
