Regarding this, how is water scarcity measured?

One of the most commonly used measures of water scarcity is the 'Falkenmark indicator' or 'water stress index'. The water stress index method is commonly used because it is straightforward, easy to use, and the data needed is readily available.

Also Know, what are the two types of water scarcity? There are two general types of water scarcity: physical and economic. Physical, or absolute, water scarcity is the result of a region's demand outpacing the limited water resources found there.

    What is water stress index?

    Water stress index is typically defined as the relationship between total water use and water availability. The closer water use is to water supply, the more likely stress will occur in natural and human systems.

    What do you mean by water stress?

    Water stress occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use. Water stress causes deterioration of fresh water resources in terms of quantity (aquifer over-exploitation, dry rivers, etc.)
