From Drop to Delta: Optimizing Water Footprint for Food Security

Abstract

Due to population growth and decreasing freshwater resources, many countries may face a decline in their ability to be self-sufficient in food production. The issue of freshwater contamination and scarcity needs to be addressed globally because a sizeable majority of the world's population lives in areas where water scarcity occurs for at least one month every year. The world economy plays a role in localized water contamination and depletion, especially as water is increasingly used for exporting goods. The idea of water footprints is a practical way to gauge how much water is needed to produce goods and services and to promote sustainability in industrial and food production. The use of water for various reasons can result in the appropriation of valuable data that can be used to examine the environmental, social, and economic effects and advance conversations about fair and sustainable water use. The idea of a water footprint ultimately aims to encourage wise and effective water use.
