Abstract

As per the recent statistics the population is increasing rapidly and the need of food and water is increasing as well but the amount of freshwater is rapidly decreasing leading to major water scarcity. Water scarcity is increasingly recognized as a global challenge, necessitating a deeper understanding of water consumption across different products. Hence, the need for water footprint increases so as to monitor the water usage of an individual and thereby implement measures to decrease the unnecessary usage of water. In the recent decade there have been studies that have calculated the water footprint based on different measures like the amount of water required to assimilate the pollutants in the freshwater reserves, based on the direct and indirect usage of water in the different day to day activities.
