Measurement of Water Scarcity

Abstract

When the balance between availability and demand of water is disturbed, problems of water scarcity begin. In this chapter an attempt is made to explain the methods of measuring water scarcity based on secondary and primary data for which Thornthwaite’s water balance method and Sullivan’s water scarcity index method have been taken, respectively. The paper explains how water scarcity can be calculated by using different data sets by different methods, and their positive and negative aspects have also been evaluated with respect to the outcome.
